Description

雙軸輸出馬達、馬達單元、動力模擬器、扭力測試裝置、轉動扭力測試裝置、輪胎測試裝置、線性致動器及勵磁裝置 Two-axis output motor, motor unit, power simulator, torque test device, rotational torque test device, tire test device, linear actuator and excitation device

本發明係關於一種雙軸輸出馬達、串聯連結包含雙軸輸出馬達之複數個馬達的馬達單元、具備雙軸輸出伺服馬達之扭力測試裝置、轉動扭力測試裝置、輪胎測試裝置、線性致動器及勵磁裝置。 The present invention relates to a two-axis output motor, a motor unit in which a plurality of motors including a two-axis output motor are connected in series, a torque test device having a two-axis output servo motor, a rotational torque test device, a tire test device, a linear actuator, and Excitation device.

本發明人等藉由採用對先前之伺服馬達大幅減低慣性之超低慣性伺服馬達，使得可施加數10~數100Hz之高頻反復負載的伺服馬達式之各種疲勞測試裝置及振動測試裝置實用化(例如專利文獻1)。 The inventors of the present invention have applied various types of fatigue test devices and vibration test devices that can apply a high-frequency repeated load of 10 to 100 Hz by applying an ultra-low inertia servo motor that greatly reduces the inertia of the previous servo motor. (for example, Patent Document 1).

上述之伺服馬達式測試裝置，由於解決過去油壓式測試裝置存在之許多嚴重問題(例如，需要設置油槽及油壓配管等大規模之油壓供給設備，需要定期更換大量液壓油，因液壓油洩漏造成作業環境、土壤污染)，因此適用範圍急遽擴大。 The above-mentioned servo motor type test device solves many serious problems in the past hydraulic type test device (for example, it is necessary to provide a large-scale oil pressure supply device such as an oil groove and a hydraulic pipe, and it is necessary to periodically replace a large amount of hydraulic oil due to hydraulic oil. The leakage caused the working environment and soil pollution), so the scope of application is rapidly expanding.

為了使伺服馬達式測試裝置之適用範圍進一步擴大，而要求維持超低慣性伺服馬達之高加速特性、及更高輸出化。 In order to further expand the range of application of the servo motor type test apparatus, it is required to maintain the high acceleration characteristics of the ultra-low inertia servo motor and to increase the output.

此外，因為伺服馬達式測試裝置之製造成本中，伺服馬達之成本所佔的比率大，所以要求使用1台伺服馬達可同時測試複數個受測體之伺服馬達式測試裝置。 In addition, since the cost of the servo motor is large in the manufacturing cost of the servo motor type test device, it is required to use a servo motor to simultaneously test a plurality of servo motor type test devices of the test object.

但是，單純將伺服馬達高輸出化時，因為需要提高伺服馬達各部之強度，所以超過輸出之增加部分而尺寸大型化，且重量增加。此外，藉此，由於伺服馬達之慣性力矩的輸出比(慣性力矩對伺服馬達之輸出的比率)增大，因而產生加速特性(包含躍度)降低，且可輸出之變動負載的頻率範圍降低之問題。 However, when the servo motor is simply outputted, it is necessary to increase the strength of each part of the servo motor. Therefore, the size is increased and the weight is increased by exceeding the increased portion of the output. Further, by this, since the output ratio of the inertia moment of the servo motor (the ratio of the moment of inertia to the output of the servo motor) is increased, the acceleration characteristic (including the hop) is lowered, and the frequency range of the variable load that can be output is lowered. problem.

此外，過去之伺服馬達因為僅有1支輸出軸，所以，為了可同時進行複數個受測體的測試，需要設置分配動力之齒輪機構等，因而有摩擦阻力增大及測試裝置大型化之問題。 In addition, since the servo motor of the past has only one output shaft, in order to test a plurality of test bodies at the same time, it is necessary to provide a gear mechanism for distributing power, and thus there is an increase in frictional resistance and an increase in size of the test device. .

(第一實施形態) (First embodiment)

首先，說明本發明實施形態之雙軸輸出伺服馬達150A。第一圖係雙軸輸出伺服馬達150A之側視圖。雙軸輸出伺服馬達150A係具備二個輸出軸150A2a、150A2b之高輸出(額定輸出37kW)的超低慣性伺服馬達。雙軸輸出伺服馬達150A具備本體框架150A1、驅動軸150A2、第一托架150A3及第二托架150A4。 First, a two-axis output servo motor 150A according to an embodiment of the present invention will be described. The first figure is a side view of the dual axis output servo motor 150A. The two-axis output servo motor 150A is an ultra-low inertia servo motor having high output (37kW rated output) of two output shafts 150A2a and 150A2b. The two-axis output servo motor 150A includes a main body frame 150A1, a drive shaft 150A2, a first bracket 150A3, and a second bracket 150A4.

本體框架150A1係概略圓筒狀之框架，並在其內周設置具有線圈之定子(無圖示)。在本體框架150A1之軸方向兩端部，以堵塞本體框架150A1之開口的方式，分別安裝有第一托架150A3與第二托架150A4。藉由本體框架150A1、第一托架150A3及第二托架150A4形成馬達箱。在第一托架150A3與第二托架150A4中分別設有自由轉動地支撐驅動軸150A2之軸承150A3b、150A4b。在驅動軸150A2之長度方向中央部的外周設有轉子(無圖示)，藉由定子所產生之轉動磁場與設於驅動軸150A2之轉子的相互作用，而對驅動軸150A2賦予轉動力。 The main body frame 150A1 is a frame having a substantially cylindrical shape, and a stator (not shown) having a coil is provided on the inner circumference thereof. The first bracket 150A3 and the second bracket 150A4 are attached to both ends of the main body frame 150A1 in the axial direction so as to close the opening of the main body frame 150A1. A motor case is formed by the body frame 150A1, the first bracket 150A3, and the second bracket 150A4. Bearings 150A3b, 150A4b that rotatably support the drive shaft 150A2 are provided in the first bracket 150A3 and the second bracket 150A4, respectively. A rotor (not shown) is provided on the outer circumference of the central portion of the drive shaft 150A2 in the longitudinal direction, and a rotational force is applied to the drive shaft 150A2 by the interaction between the rotating magnetic field generated by the stator and the rotor provided on the drive shaft 150A2.

驅動軸150A2之一端部150A2a(第一圖之右端部)貫穿第一托架150A3，從馬達箱突出於外部，而成為輸出軸150A2a。此外，驅動軸 150A2之另一端部150A2b貫穿第二托架150A4，從馬達箱突出於外部，而成為第二輸出軸150A2b。在第二托架150A4中內藏用以檢測驅動軸150A2之另一端部150A2b的轉動之旋轉編碼器(無圖示)。 One end portion 150A2a (the right end portion of the first figure) of the drive shaft 150A2 penetrates the first bracket 150A3 and protrudes from the motor case to the outside to become the output shaft 150A2a. In addition, the drive shaft The other end portion 150A2b of the 150A2 penetrates the second bracket 150A4 and protrudes from the motor case to the outside to become the second output shaft 150A2b. A rotary encoder (not shown) for detecting the rotation of the other end portion 150A2b of the drive shaft 150A2 is housed in the second bracket 150A4.

此外，在第一托架150A3及第二托架150A4之下面，分別設 有用於固定雙軸輸出伺服馬達150A之一對塞孔150A3t及150A4t。過去之伺服馬達僅在負載側(輸出軸突出側)之托架的安裝座面(第一圖之右側面)設有與驅動軸平行延伸之固定用塞孔。在精密機械測試以外之用途上，僅藉由設於負載側托架之安裝座面的塞孔固定即可，但特別是施加數10Hz(例如20Hz)以上的高頻之動載荷的精密機械測試裝置(例如疲勞測試裝置及振動測試裝置)中，使用額定輸出為10kW程度以上之高輸出的伺服馬達之情況下，僅以托架之安裝座面固定，無法在與驅動軸垂直之方向完全固定伺服馬達，會發生例如數μm~數10μm程度之微小振幅的振動，而造成對測試結果無法忽視之誤差。 In addition, under the first bracket 150A3 and the second bracket 150A4, respectively There is a pair of plug holes 150A3t and 150A4t for fixing the two-axis output servo motor 150A. In the past, the servo motor was provided with a fixing plug hole extending parallel to the drive shaft only on the mounting seat surface (the right side surface of the first drawing) of the carrier on the load side (the output shaft protruding side). For applications other than precision mechanical testing, it can be fixed only by the plug hole provided on the mounting surface of the load side bracket, but in particular, precision mechanical testing using high frequency dynamic loads of several 10 Hz (for example, 20 Hz) or more is applied. In a device (for example, a fatigue tester and a vibration tester), when a servo motor with a high output of a rated output of 10 kW or more is used, it is fixed only by the mounting surface of the bracket, and cannot be completely fixed in a direction perpendicular to the drive shaft. In the servo motor, a small amplitude vibration of, for example, several μm to several 10 μm occurs, and an error that cannot be ignored in the test result is caused.

本發明人等經過多次振動分析及測試結果，發現在各托架之 下面，藉由各2處增設延伸於與驅動軸垂直的方向之固定用塞孔，可顯著(例如1位數程度)改善振動雜訊。除了負載側托架的安裝座面之外，藉由也在各托架之下面設置塞孔，使用此等塞孔以螺栓固定伺服馬達，振動雜訊減低，且可進行更高精度之機械測試。 The inventors of the present invention have repeatedly analyzed the vibration and the test results and found that in each of the brackets Next, by adding a fixing plug hole extending in a direction perpendicular to the drive shaft at each of the two places, vibration noise can be remarkably improved (for example, at a single digit). In addition to the mounting surface of the load side bracket, by inserting a plug hole under each bracket, the servo motor is bolted using these plug holes, vibration noise is reduced, and mechanical testing with higher precision can be performed. .

此外，伺服馬達150A係構成為，因額定輸出高達37kW，運 轉時之發熱量亦較大，而藉由水冷將內部產生之熱向外部散熱之方式。在本體框架150A1之上部設有連接有用於供給及排出冷卻水之外部配管的2個管接頭150A6。 In addition, the servo motor 150A is configured to operate at a rated output of up to 37 kW. The heat generated during the turn is also large, and the heat generated inside is dissipated to the outside by water cooling. Two pipe joints 150A6 to which an external pipe for supplying and discharging cooling water is connected are provided above the main body frame 150A1.

本實施形態係使用串聯連結上述之雙軸輸出伺服馬達150A 與具有一個輸出軸150B2a之伺服馬達150B的伺服馬達單元150。第二圖係本發明實施形態之伺服馬達單元150的側視圖。伺服馬達單元150具有1個驅動軸152。 In this embodiment, the above-described two-axis output servo motor 150A is connected in series. A servo motor unit 150 with a servo motor 150B having an output shaft 150B2a. The second drawing is a side view of the servo motor unit 150 of the embodiment of the present invention. The servo motor unit 150 has one drive shaft 152.

另外，關於伺服馬達單元150之以下說明中，將驅動軸152 突出之側(第二圖之右側)稱為負載側，將其相反側稱為反負載側。雙軸輸出伺服馬達150A及伺服馬達150B係分別產生最大達到350N‧m之轉矩，將轉動部之慣性力矩抑制在10-2(kg‧m2)以下的額定輸出為37kW之大輸出超低慣性伺服馬達。 In the following description of the servo motor unit 150, the side on which the drive shaft 152 protrudes (the right side in the second diagram) is referred to as the load side, and the opposite side is referred to as the counter load side. The two-axis output servo motor 150A and the servo motor 150B generate torques up to 350 N·m, respectively, and the inertial torque of the rotating portion is suppressed to 10 -2 (kg‧m 2 ) or less. The rated output is 37 kW. Inertial servo motor.

伺服馬達150B具備本體框架150B1、驅動軸150B2、負載側 托架150B3、反負載側托架150B4及旋轉編碼器150B5。本體框架150B1及負載側托架150B3係與雙軸輸出伺服馬達150A之本體框架150A1及第一托架150A3相同者，且在本體框架150B1之上部設有連接有用於供給及排出冷卻水之外部配管的2個管接頭150B6。反負載側托架150B4係與雙軸輸出伺服馬達150A之第二托架150A4為概略相同構成者，不過並未內藏旋轉編碼器，而係如後述將旋轉編碼器150B5外加於第二托架150A4。此外，亦在負載側托架150B3與反負載側托架150B4之下面分別設有一對塞孔150B3t及150B4t。 The servo motor 150B includes a main body frame 150B1, a drive shaft 150B2, and a load side. The bracket 150B3, the counter load side bracket 150B4, and the rotary encoder 150B5. The main body frame 150B1 and the load side bracket 150B3 are the same as the main body frame 150A1 and the first bracket 150A3 of the biaxial output servo motor 150A, and an external pipe for supplying and discharging cooling water is connected to the upper portion of the main body frame 150B1. 2 pipe joints 150B6. The counter-load side bracket 150B4 is substantially the same as the second bracket 150A4 of the two-axis output servo motor 150A. However, the rotary encoder is not incorporated, and the rotary encoder 150B5 is applied to the second bracket as will be described later. 150A4. Further, a pair of plug holes 150B3t and 150B4t are respectively provided on the lower surface of the load side bracket 150B3 and the counter load side bracket 150B4.

驅動軸150B2之負載側的一端部150B2a貫穿負載側托架 150B3，並從馬達箱突出於外部而成為輸出軸150B2a。另外，在反負載側托架150B4之安裝座面(第二圖之左側面)安裝有檢測驅動軸150B2之角度位置的旋轉編碼器150B5，驅動軸150B2之另一端部150B2b貫穿反負載側托架 150B4，並收容於旋轉編碼器內。 One end portion 150B2a of the load side of the drive shaft 150B2 penetrates the load side bracket 150B3, and protrudes from the motor case to the outside to become the output shaft 150B2a. Further, a rotary encoder 150B5 for detecting the angular position of the drive shaft 150B2 is attached to the mounting surface (the left side surface of the second drawing) of the counter load side bracket 150B4, and the other end portion 150B2b of the drive shaft 150B2 is inserted through the counter load side bracket. 150B4, and is housed in a rotary encoder.

如第二圖所示，伺服馬達150B之輸出軸150B2a與雙軸輸出 伺服馬達150A之第二輸出軸150A2b係藉由耦合器150C連結。此外，伺服馬達150B之負載側托架150B3與雙軸輸出伺服馬達150A之第二托架150A4係藉由連結凸緣150D隔開指定間隔而連結。 As shown in the second figure, the output shaft 150B2a of the servo motor 150B and the two-axis output The second output shaft 150A2b of the servo motor 150A is coupled by a coupler 150C. Further, the load side bracket 150B3 of the servo motor 150B and the second bracket 150A4 of the two-axis output servo motor 150A are coupled by a connection flange 150D at a predetermined interval.

連結凸緣150D具有圓筒狀之胴體部150D1、以及從胴體部 150D1之軸方向兩端部分別延伸於半徑方向外側的2個凸緣部150D2。在各凸緣部150D2中，在對應於設於負載側托架150B3及第二托架150A4之安裝座面的塞孔之位置設有螺栓固定用貫穿孔，並以螺栓固定於負載側托架150B3及第二托架150A4上。 The connecting flange 150D has a cylindrical body portion 150D1 and a body portion Both end portions of the 150D1 in the axial direction extend through the two flange portions 150D2 on the outer side in the radial direction. In each of the flange portions 150D2, a bolt fixing through hole is provided at a position corresponding to a plug hole provided in the mounting seat surface of the load side bracket 150B3 and the second bracket 150A4, and is bolted to the load side bracket. 150B3 and second bracket 150A4.

另外，伺服馬達單元150中設有用於檢測驅動軸150B2之角 度位置的2個旋轉編碼器(內藏於雙軸輸出伺服馬達150A之第二托架150A4者、與安裝於伺服馬達150B之反負載側托架150B4的旋轉編碼器150B5)，不過伺服馬達單元150之驅動控制時通常僅使用一方旋轉編碼器，另一方使用於維修及驅動狀態之監視。 In addition, the servo motor unit 150 is provided with a corner for detecting the drive shaft 150B2. Two rotary encoders at the position (the second encoder 150A4 of the two-axis output servo motor 150A and the rotary encoder 150B5 of the counter load side bracket 150B4 of the servo motor 150B), but the servo motor unit In the case of 150 drive control, only one rotary encoder is usually used, and the other is used for maintenance and drive state monitoring.

例如，進行振動測試及動力傳達裝置之耐久測試(轉動扭力 測試)時，需要高速(高頻)且變動大之軸轉矩。如此，為了產生高頻且變動大之轉矩，需要轉子之慣性力矩(慣性)小、且大容量(高輸出)之馬達。為了實現此種伺服馬達，需要使轉子細長。但是，使轉子超過某種程度而細長時，因為轉子(轉動軸)之剛性降低，所以呈弓形翹曲之轉子的振動顯著，馬達將無法正常動作。因此，如習知所示藉由一對軸承僅在兩端部軸撐轉動軸之構成，在維持低慣性力矩狀態下大容量化仍有限度。 For example, performing vibration testing and endurance testing of power transmission devices (rotating torque) When testing), high-speed (high-frequency) and large-variation shaft torque is required. As described above, in order to generate a high-frequency and variable torque, a motor having a small inertia moment (inertia) and a large capacity (high output) of the rotor is required. In order to realize such a servo motor, it is necessary to make the rotor elongated. However, when the rotor is elongated over a certain extent, since the rigidity of the rotor (rotating shaft) is lowered, the vibration of the rotor which is bowed and warped is remarkable, and the motor cannot operate normally. Therefore, as shown in the prior art, by the configuration in which the pair of bearings only pivots the rotation shaft at both end portions, there is still a limit to increase the capacity while maintaining the low moment of inertia.

本實施形態之伺服馬達單元150，因為藉由耦合器150C連結 之長的轉子係在長度方向之兩端部與連結部附近之2處的合計4處藉由軸承支撐，所以即使轉子長條化仍可保持較高的剛性而穩定地動作，藉此，可產生過去伺服馬達所達不到之高頻且變動大的轉矩。例如，伺服馬達單元150單體(無負載狀態)可達成30000rad/s2以上之角加速度。 In the servo motor unit 150 of the present embodiment, the long rotor connected by the coupler 150C is supported by the bearing at the total of four places in the longitudinal direction and the vicinity of the connecting portion, so that the rotor is elongated. It is possible to maintain a high rigidity and to operate stably, whereby a high frequency and a large fluctuation torque which cannot be obtained by the servo motor in the past can be generated. For example, the servo motor unit 150 can achieve an angular acceleration of 30,000 rad/s 2 or more in a single (no load state).

另外，本實施形態之伺服馬達單元150係連結2個伺服馬達(2 個馬達箱與2個轉動軸)而構成，不過如第三圖所示，亦可在1組長條馬達之長度方向中途設置一個以上軸承，並在兩端部及其中途之1處以上軸撐驅動軸而構成。 Further, the servo motor unit 150 of the present embodiment is connected to two servo motors (2). One motor box and two rotating shafts are included, but as shown in the third figure, one or more bearings may be provided in the middle of the length direction of one set of long motors, and one or more ends of the two ends and one of them The drive shaft is constructed.

其次，說明本發明第一實施形態之轉動扭力測試裝置1的構 成。第四圖係本發明第一實施形態之轉動扭力測試裝置1的側視圖。轉動扭力測試裝置1係將汽車用離合器作為受測體T1進行轉動扭力測試之裝置，且使受測體T1轉動，並在受測體T1之輸入軸與輸出軸(例如離合器蓋與離合器圓盤)之間施加設定之固定或變動轉矩。轉動扭力測試裝置1具備支撐轉動扭力測試裝置1之各部的架台10；與受測體T1一起轉動，並在受測體T1上施加指定之轉矩的載荷賦予部100；自由轉動地支撐載荷賦予部100之軸承部20、30及40；電性連接載荷賦予部100內外之滑動環部50及60；檢測載荷賦予部100之轉數的旋轉編碼器70；以設定之轉動方向及轉數轉動驅動載荷賦予部100之變頻調速馬達(Inverter motor)80；驅動滑輪91及驅動皮帶92(定時皮帶)。 Next, the structure of the rotational torque testing device 1 according to the first embodiment of the present invention will be described. to make.

In particular, by using a servo motor unit 150 that is connected in series with a plurality of ultra-low inertia servo motors, it is possible to control a large torque with a high angular acceleration (angular jump), and the output of the automobile engine can be correctly reproduced ( Especially the torque vibration of the reciprocating engine). Further, by using the servo motor unit 150, the responsiveness of the torque control is also improved, and a response time of 3 ms or less can be achieved. The rotational driving device of such a configuration is not limited to the rotational torque testing device, but can be used as a power source for various devices. Especially in automotive (or automotive parts) test equipment, it can be used as a power simulator (simulation engine) that can output the power to simulate the output of various engines. Further, since the torque generated by the servo motor unit 150 is controlled with high precision, the reproducibility is extremely high and there is no difference from each other. Therefore, it is possible to give a more uniform load and test with higher reproducibility than the test using the physical engine in the past.

第七圖所示之動力模擬器1a與上述轉動扭力測試裝置1的不同之處為具備軸承部1020、滑動環1401及安裝部173。軸承部1020係與後述之第二實施形態的軸承部1020為相同構成者，且內藏檢測連結軸170(第二實施形態係連結軸1170)之轉矩的轉矩感測器。滑動環1401安裝於軸承部1020，並將從內藏於軸承部1020之轉矩感測器輸出的信號取出至外部。此外，安裝部173係凸緣接頭，且安裝於連結軸170之前端部。如此構成之動力模擬器1a使用於引擎輔機類(例如緩衝滑輪、交流發電機、平衡軸、起動馬達、環形齒輪、水泵、油泵、鏈條、定時皮帶、耦合器、VCT)、動力傳達裝置、輪胎等耐久測試等。 The power simulator 1a shown in the seventh embodiment is different from the above-described rotational torque testing device 1 in that it includes a bearing portion 1020, a slide ring 1401, and a mounting portion 173. The bearing portion 1020 is the same as the bearing portion 1020 of the second embodiment to be described later, and includes a torque sensor that detects the torque of the connecting shaft 170 (the second embodiment is a coupling shaft 1170). The slide ring 1401 is attached to the bearing portion 1020, and takes out a signal output from the torque sensor built in the bearing portion 1020 to the outside. Further, the attachment portion 173 is a flange joint and is attached to the front end portion of the coupling shaft 170.

第十五圖係本實施形態之轉矩賦予單元130及第一齒輪盒141的側剖面圖。轉矩賦予單元130具備機殼131、固定於機殼131內之轉矩賦予用伺服馬達單元132及減速機133。另外，轉矩賦予用伺服馬達單元132係與第一實施形態之伺服馬達單元150為相同構成者，不過亦可取代伺服馬達單元150而單獨使用第一實施形態之伺服馬達150B。在機殼131之軸方向一端側(圖中右側)形成有管狀部131a。管狀部131a經由軸連接部141b1而***第一齒輪盒141內，可在第一齒輪盒141內轉動地支撐。此外，在管狀部131a上裝設齒輪141b3。 The fifteenth diagram is a side cross-sectional view of the torque applying unit 130 and the first gear case 141 of the present embodiment. The torque applying unit 130 includes a casing 131, a torque applying servo motor unit 132 and a speed reducer 133 that are fixed in the casing 131. Further, the torque applying servo motor unit 132 is the same as the servo motor unit 150 of the first embodiment, but the servo motor 150B of the first embodiment may be used alone instead of the servo motor unit 150. A tubular portion 131a is formed on one end side (the right side in the drawing) of the casing 131 in the axial direction. The tubular portion 131a is inserted into the first gear case 141 via the shaft connecting portion 141b1, and is rotatably supported in the first gear case 141. Further, a gear 141b3 is attached to the tubular portion 131a.

減速機133具有輸入軸133a與輸出軸133b，將輸入於輸入軸133a之轉動運動減速而輸出至輸出軸133b。減速機133之輸入軸133a係藉由耦合器134而與轉矩賦予用伺服馬達單元132之輸出軸132a連結。此外，減速機133之輸出軸133b可在機殼131之管狀部131a的內部轉動地支撐，並且從管狀部131a之前端部突出。從管狀部131a突出之減速機133的輸出軸133b連接於第一齒輪盒141之軸連接部141b2。 The speed reducer 133 has an input shaft 133a and an output shaft 133b, and decelerates the rotational motion input to the input shaft 133a, and outputs it to the output shaft 133b. The input shaft 133a of the speed reducer 133 is coupled to the output shaft 132a of the torque applying servo motor unit 132 by the coupler 134. Further, the output shaft 133b of the speed reducer 133 is rotatably supported inside the tubular portion 131a of the casing 131, and protrudes from the front end portion of the tubular portion 131a. The output shaft 133b of the speed reducer 133 protruding from the tubular portion 131a is coupled to the shaft connecting portion 141b2 of the first gear case 141.

如第十四圖所示，減速機133之輸出軸133b係經由耦合器151而連結於測試對象之傳動單元W1的輸入軸W1a。傳動單元W1之輸出軸W1b係經由轉矩感測器160而連接於第二齒輪盒142之軸連接部142b。 As shown in Fig. 14, the output shaft 133b of the speed reducer 133 is coupled to the input shaft W1a of the transmission unit W1 of the test object via the coupler 151. The output shaft W1b of the transmission unit W1 is coupled to the shaft connection portion 142b of the second gear case 142 via the torque sensor 160.

在第二齒輪盒142之軸連接部142a上經由中繼軸143而連接 傳動單元W2之輸出軸W2b。傳動單元W2之輸入軸W2a係經由耦合器152而連接於第一齒輪盒141之軸連接部141a2。 Connected to the shaft connecting portion 142a of the second gear case 142 via the relay shaft 143 Output shaft W2b of transmission unit W2. The input shaft W2a of the transmission unit W2 is coupled to the shaft connection portion 141a2 of the first gear case 141 via the coupler 152.

此處，裝設於第一齒輪盒141之軸連接部141a1的從動滑輪 123之軸123a、與裝設於軸連接部141a2之軸，係構成在第一齒輪盒141之內部經由耦合器153而連結，且兩者成為一體而轉動。此外，在裝設於軸連接部141a1之從動滑輪123的軸123a上裝設齒輪141a3。在連接於軸連接部141b1之管狀部131a上，於第一齒輪盒141之內部裝設齒輪141b3。如第十四圖(a)所示，齒輪141a3與齒輪141b3經由中間齒輪141i而咬合，在連接於軸連接部141a1及141a2之軸、與連接於軸連接部141b1的軸之間可彼此傳達轉動運動。另外，由於中間齒輪141i係介於齒輪141a3與齒輪141b3之間，因此從動滑輪123與中繼軸143及轉矩賦予單元130的機殼131可在相同方向轉動。 Here, the driven pulley mounted on the shaft connecting portion 141a1 of the first gear case 141 The shaft 123a of 123 and the shaft mounted on the shaft connecting portion 141a2 are connected to each other via the coupler 153 inside the first gear case 141, and are integrally rotated. Further, a gear 141a3 is attached to the shaft 123a of the driven pulley 123 mounted on the shaft connecting portion 141a1. A gear 141b3 is attached to the inside of the first gear case 141 on the tubular portion 131a connected to the shaft connecting portion 141b1. As shown in Fig. 14(a), the gear 141a3 and the gear 141b3 are engaged via the intermediate gear 141i, and can transmit and rotate with each other between the shaft connected to the shaft connecting portions 141a1 and 141a2 and the shaft connected to the shaft connecting portion 141b1. motion. Further, since the intermediate gear 141i is interposed between the gear 141a3 and the gear 141b3, the driven pulley 123 and the relay shaft 143 and the casing 131 of the torque applying unit 130 can be rotated in the same direction.

在連接於軸連接部142a之軸部(中繼軸143之一端部)裝設 有齒輪142a1。此外，在連接於軸連接部142b之軸部連接有齒輪142b1。齒輪142a1與142b1在第二齒輪盒142之內部經由中間齒輪142i而咬合，在連接於軸連接部142a之軸與連接於軸連接部142b的軸之間可彼此傳達轉動運動。另外，由於中間齒輪142i介於齒輪142a1與齒輪142b1之間，因此連接於軸連接部142a之軸與連接於軸連接部142b之軸可在相同方向轉動。 Mounted on a shaft portion (one end portion of the relay shaft 143) connected to the shaft connecting portion 142a There is a gear 142a1. Further, a gear 142b1 is connected to a shaft portion connected to the shaft connecting portion 142b. The gears 142a1 and 142b1 are engaged by the intermediate gear 142i inside the second gear case 142, and the rotational motion can be transmitted to each other between the shaft connected to the shaft connecting portion 142a and the shaft connected to the shaft connecting portion 142b. Further, since the intermediate gear 142i is interposed between the gear 142a1 and the gear 142b1, the shaft connected to the shaft connecting portion 142a and the shaft connected to the shaft connecting portion 142b are rotatable in the same direction.

因此，本實施形態中，驅動工件轉動用伺服馬達121(第十 四圖)時，即轉動驅動從動滑輪123及經由齒輪與從動滑輪123連接之機殼131(第十五圖)。如前述，因為轉矩賦予用伺服馬達單元132固定於機殼131，所以機殼131與轉矩賦予用伺服馬達成為一體而轉動。因而，在機殼131轉動狀態下驅動轉矩賦予用伺服馬達單元132時，減速機133之輸出軸 133b係以機殼131之轉數與輸出軸133b藉由轉矩賦予用伺服馬達單元132之轉數相加的轉數來轉動。 Therefore, in the present embodiment, the servo motor 121 for driving the workpiece is driven (tenth In the case of FIG. 4, the driven pulley 123 and the casing 131 connected to the driven pulley 123 via a gear are rotated (fifteenth figure). As described above, since the torque applying servo motor unit 132 is fixed to the casing 131, the casing 131 and the torque applying servomotor are integrally rotated. Therefore, when the torque applying servo motor unit 132 is driven in the state in which the casing 131 is rotated, the output shaft of the speed reducer 133 133b is rotated by the number of revolutions of the casing 131 and the output shaft 133b by the number of revolutions of the torque applying servo motor unit 132.

傳動單元W2係與傳動單元W1同型(相同減速比)。此外， 齒輪盒141及142之齒輪比均為1：1。因而，連接於第一齒輪盒141之軸連接部141a2與141b2的軸之轉數概等。另外，傳動單元W2如上述，係用於調整連接於軸連接部141a2與141b2之軸的轉數而利用的一種虛擬工件，並非扭力測試之對象。 The transmission unit W2 is of the same type as the transmission unit W1 (same reduction ratio). In addition, The gear ratios of the gear boxes 141 and 142 are both 1:1. Therefore, the number of revolutions of the shaft connected to the shaft connecting portions 141a2 and 141b2 of the first gear case 141 is equal. Further, as described above, the transmission unit W2 is a virtual workpiece used for adjusting the number of revolutions of the shafts connected to the shaft connecting portions 141a2 and 141b2, and is not the object of the torque test.

本實施形態中，例如藉由定速驅動工件轉動用伺服馬達 121，並且藉由轉矩賦予用伺服馬達單元132(第十五圖)使輸出軸132a往復驅動，可使傳動單元W1之輸入軸W1a轉動，並施加周期性變動之轉矩。 In the present embodiment, for example, a servo motor for rotating a workpiece is driven by a constant speed. 121, and the output shaft 132a is reciprocally driven by the torque applying servo motor unit 132 (fifteenth drawing), the input shaft W1a of the transmission unit W1 can be rotated, and the periodically varying torque can be applied.

(第四實施形態) (Fourth embodiment)

其次，說明本發明之第四實施形態。第十六圖係本發明第四實施形態之扭力測試裝置的仰視圖。如第十六圖所示，本實施形態之扭力測試裝置100A除了不使用虛擬工件，而藉由中繼軸143A直接連結耦合器152與第二齒輪盒142之軸連接部142a之外，與第三實施形態之扭力測試裝置100相同。另外，以下之第四實施形態的說明中，對具有與第三實施形態相同或類似功能之要素註記相同或類似符號，而省略重複之說明。 Next, a fourth embodiment of the present invention will be described. Figure 16 is a bottom view of a torque testing device according to a fourth embodiment of the present invention. As shown in the sixteenth embodiment, the torque testing device 100A of the present embodiment directly connects the coupler 152 and the shaft connecting portion 142a of the second gear case 142 by the relay shaft 143A, except that the dummy workpiece is not used. The torque testing device 100 of the third embodiment is the same. In the following description of the fourth embodiment, the same or similar elements as those of the third embodiment are denoted by the same or similar reference numerals, and the description thereof will not be repeated.

本實施形態中，中繼軸143A之轉數(亦即，轉矩賦予單元130之機殼131的轉數)與連接於第一齒輪盒141之軸連接部141b2的軸之轉數(亦即，傳動單元W1之輸入軸W1a的轉數)不同。因而，本實施形態中，係以彌補傳動單元W1之輸入輸出軸上轉數的變化之方式，而轉動驅動轉矩賦予單元130之轉矩賦予用伺服馬達單元132(第十五圖)。例如，傳動單元 W1之減速比係1/3.5，將輸入軸W1a之轉數設為4000rmp，將輸出軸W1b之轉數設為1143rpm來進行扭力測試時，藉由設定工件轉動用伺服馬達121之轉數，以使1143rpm之轉動賦予轉矩賦予單元130的機殼131，並且設定轉矩賦予用伺服馬達單元132之轉數，以使機殼131對減速機133之輸出軸133b的相對轉數成為2857rpm，可將傳動單元W1之輸入軸W1a的轉數設為4000rrpm。 In the present embodiment, the number of revolutions of the relay shaft 143A (that is, the number of revolutions of the casing 131 of the torque applying unit 130) and the number of revolutions of the shaft connected to the shaft connecting portion 141b2 of the first gear case 141 (that is, The number of revolutions of the input shaft W1a of the transmission unit W1 is different. Therefore, in the present embodiment, the torque application servo motor unit 132 (fifteenth diagram) of the torque-driven torque applying unit 130 is rotated so as to compensate for the change in the number of revolutions of the input/output shaft of the transmission unit W1. For example, the drive unit The reduction ratio of W1 is 1/3.5, the number of revolutions of the input shaft W1a is 4000 rpm, and the number of revolutions of the output shaft W1b is 1143 rpm. When the torque test is performed, the number of revolutions of the servo motor 121 for workpiece rotation is set. The rotation of 1143 rpm is given to the casing 131 of the torque applying unit 130, and the number of revolutions of the torque applying servo motor unit 132 is set so that the relative number of revolutions of the casing 131 to the output shaft 133b of the speed reducer 133 becomes 2857 rpm. The number of revolutions of the input shaft W1a of the transmission unit W1 was set to 4000 rpm.

如此，本實施形態中，可進行動力循環，同時不使用虛擬工 件而進行傳動單元W1之扭力測試。 In this way, in the present embodiment, the power cycle can be performed without using the virtual worker. The torque test of the transmission unit W1 is performed.

此外，本實施形態中，為了藉由響應性高之伺服馬達進行工 件之轉動驅動及轉矩賦予，亦可在進行扭力測試中變更傳動單元W1之齒輪比。亦即，本實施形態中，因為可與變更傳動單元W1之齒輪比而改變輸出軸W1b之轉數同步，使轉矩賦予用伺服馬達單元132之轉數急速改變，所以，即使變更傳動單元W1之齒輪比，仍不致對齒輪盒141、142內之齒輪及傳動單元W1施加過度負載而造成破損。 Further, in the present embodiment, in order to work with a servo motor having high responsiveness The rotational drive and torque imparting of the piece can also change the gear ratio of the transmission unit W1 during the torque test. In other words, in the present embodiment, since the number of revolutions of the output shaft W1b can be changed in synchronization with changing the gear ratio of the transmission unit W1, the number of revolutions of the torque applying servo motor unit 132 is rapidly changed. Therefore, even if the transmission unit W1 is changed, The gear ratio does not cause excessive damage to the gears and the transmission unit W1 in the gear cases 141, 142 to cause damage.

Specifically, the output shafts DG1a and DG1b of the differential gear DG1 are connected to the relay shafts 143B1 and 143B2 via the second gear cases 142B1 and 142B2, respectively.

此外，第一齒輪盒141B除了分別安裝有轉矩賦予單元130之 機殼131的管狀部131a以及傳動單元TR1的輸入軸TR1a之軸連接部141Bb1、141Bb2(與第三實施形態之軸連接部141b1、141b2相同功能)，以及連接工件轉動用伺服馬達121之輸出軸121a與中繼軸143B1的軸連接部141Ba1、141Ba2之外，還具有與中繼軸143B2連接之軸連接部143Bc。此外，工件轉動用伺服馬達121之輸出軸121a與中繼軸143B1，係經由配置於第一齒輪盒141內之耦合器153B而連結。再者，傳動單元TR1之輸入軸TR1a與轉矩賦予單元130之減速機133的輸出軸133b，係經由配置於第一齒輪盒141內之耦合器151B而連結。 Further, the first gear case 141B is mounted with the torque imparting unit 130, respectively.

如第十八圖所示，動力傳達系統W4係概略平行地形成有傳 動單元TR2之輸入軸TR2a、與差速齒輪DG2之輸出軸DG2a、DG2b的橫放引擎用動力傳達系統。因而本實施形態中，將差速齒輪DG2之一方輸出軸DG2a照樣連接於第一齒輪盒141C，而僅將另一方輸出軸DG2b經由第二齒輪盒142C連接於中繼軸143C。 As shown in the eighteenth figure, the power transmission system W4 is formed in a schematic parallel manner. The power transmission system for the horizontal direction of the input shaft TR2a of the movable unit TR2 and the output shafts DG2a and DG2b of the differential gear DG2.

此外，本實施形態中，與第四及第五實施形態同樣，因為傳 動單元TR2之輸入軸TR2a的轉數、與差速齒輪DG2之輸出軸DG2a及中繼軸143C的轉數不同，所以係以彌補上述轉數之差的方式，控制轉矩賦予用馬達131(第十五圖)之轉數。 Further, in the present embodiment, as in the fourth and fifth embodiments, The number of revolutions of the input shaft TR2a of the movable unit TR2 is different from the number of revolutions of the output shaft DG2a of the differential gear DG2 and the relay shaft 143C.

(第十三實施形態) (Thirteenth Embodiment)

其次，說明本發明第十三實施形態之低速型轉動扭力測試裝置。第二十六圖係本發明第十三實施形態之扭力測試裝置3100的側視圖。本實施形態之扭力測試裝置3100係進行具有2個轉動軸之受測體T1(例如FR車用傳動單元)的轉動扭力測試之裝置。亦即，扭力測試裝置3100藉由使受測體T1之2個轉動軸同步轉動，並對2個轉動軸之轉動賦予相位差，負載轉矩並使受測體T1之2個轉動軸轉動。本實施形態之扭力測試裝置3100具備第一驅動部3110、第二驅動部3120、及綜合控制扭力測試裝置3100之動作的控制單元C3。 Next, a low-speed rotary torque testing device according to a thirteenth embodiment of the present invention will be described. The twenty-sixth embodiment is a side view of the torque testing device 3100 of the thirteenth embodiment of the present invention. The torque testing device 3100 of the present embodiment is a device for performing a rotational torque test of a subject T1 (for example, an FR vehicle transmission unit) having two rotational axes. In other words, the torque testing device 3100 rotates the two rotating shafts of the subject T1 in synchronization with each other, and imparts a phase difference to the rotation of the two rotating shafts, and the load torque rotates the two rotating shafts of the subject T1. The torque testing device 3100 of the present embodiment includes a first driving unit 3110, a second driving unit 3120, and a control unit C3 that comprehensively controls the operation of the torque testing device 3100.

首先，說明第一驅動部3110之構造。第二十七圖係欠缺第一驅動部3110之一部分的側視圖。第一驅動部3110具備本體3110a、及在指定高度支撐該本體3110a之基座3110b。本體3110a係具備伺服馬達單元150、減速機3113、箱3114、心軸3115、夾盤裝置3116、轉矩感測器3117、滑動環3119a及電刷3119b，本體3110a係組裝在水平配置於基座3110b之最上部的活動板 3111上。伺服馬達單元150係與第一實施形態相同者。伺服馬達單元150將輸出軸(無圖示)朝向水平方向而固定於活動板3111上。此外，基座3110b之活動板3111可滑動地設於伺服馬達單元150的輸出軸方向(第二十六圖之左右方向)。 First, the configuration of the first driving unit 3110 will be described. The twenty-seventh drawing is a side view of a portion lacking the first driving portion 3110. The first driving unit 3110 includes a main body 3110a and a susceptor 3110b that supports the main body 3110a at a predetermined height. The main body 3110a includes a servo motor unit 150, a speed reducer 3113, a case 3114, a spindle 3115, a chuck device 3116, a torque sensor 3117, a slide ring 3119a, and a brush 3119b. The body 3110a is assembled horizontally on the base. The topmost movable board of 3110b 3111. The servo motor unit 150 is the same as that of the first embodiment. The servo motor unit 150 fixes the output shaft (not shown) to the movable plate 3111 in the horizontal direction. Further, the movable plate 3111 of the base 3110b is slidably provided in the output shaft direction of the servo motor unit 150 (the left-right direction of the twenty-sixth drawing).

伺服馬達單元150之輸出軸(無圖示)藉由耦合器(無圖示) 而連結於減速機3113之輸入軸(無圖示)。減速機3113之輸出軸3113a連結於轉矩感測器3117之一端部。轉矩感測器3117之另一端部連結於心軸3115之一端部。心軸3115藉由固定於箱3114之框架3114b的軸承3114a而自由轉動地支撐。在心軸3115之另一端部固定有用於將受測體T1之一端部(轉動軸之一個)安裝於第一驅動部3110的夾盤裝置3116。驅動伺服馬達單元150時，伺服馬達單元150之輸出軸的轉動運動藉由減速機3113減速後，經由轉矩感測器3117、心軸3115及夾盤裝置3116而傳達至受測體T1之一端部。此外，在心軸3115上安裝有檢測心軸3115之轉動角的旋轉編碼器(無圖示)。 The output shaft of the servo motor unit 150 (not shown) is coupled by a coupler (not shown) It is connected to the input shaft of the reducer 3113 (not shown). The output shaft 3113a of the speed reducer 3113 is coupled to one end of the torque sensor 3117. The other end of the torque sensor 3117 is coupled to one end of the mandrel 3115. The mandrel 3115 is rotatably supported by a bearing 3114a fixed to the frame 3114b of the case 3114. A chuck device 3116 for attaching one end portion (one of the rotating shafts) of the subject T1 to the first driving portion 3110 is fixed to the other end portion of the mandrel 3115. When the servo motor unit 150 is driven, the rotational motion of the output shaft of the servo motor unit 150 is decelerated by the speed reducer 3113, and then transmitted to one end of the subject T1 via the torque sensor 3117, the spindle 3115, and the chuck device 3116. unit. Further, a rotary encoder (not shown) that detects the rotation angle of the spindle 3115 is attached to the spindle 3115.

如第二十七圖所示，減速機3113固定於箱3114之框架3114b 上。此外，減速機3113具備齒輪箱、及經由軸承並藉由齒輪箱自由轉動地支撐之齒輪機構(無圖示)。亦即，箱3114亦具有覆蓋從減速機3113至夾盤裝置3116的動力傳達軸，並且在減速機3113及心軸3115之位置自由轉動地支撐該動力傳達軸的作為裝置框架之功能。亦即，連接轉矩感測器3117之一端部的減速機3113之齒輪機構、與連接轉矩感測器3117之另一端部的心軸3115均經由軸承而自由轉動地支撐於箱3114之框架3114b上。因而，因為轉矩感測器3117中不致施加由於減速機3113之齒輪機構及心軸3115(及夾盤裝置3116)的重量而產生之彎曲力矩，而僅施加測試載荷(扭力載荷)，所以 可高精度檢測出測試載荷。 As shown in the twenty-seventh figure, the speed reducer 3113 is fixed to the frame 3114b of the box 3114. on. Further, the speed reducer 3113 includes a gear case and a gear mechanism (not shown) that is rotatably supported by a gear box via a bearing. That is, the tank 3114 also has a function as a device frame that covers the power transmission shaft from the speed reducer 3113 to the chuck device 3116, and rotatably supports the power transmission shaft at the position of the speed reducer 3113 and the spindle 3115. That is, the gear mechanism of the speed reducer 3113 that connects one end of the torque sensor 3117 and the spindle 3115 that connects the other end of the torque sensor 3117 are rotatably supported by the frame of the case 3114 via bearings. 3114b. Therefore, since the bending moment generated by the weight mechanism of the speed reducer 3113 and the weight of the spindle 3115 (and the chuck device 3116) is not applied in the torque sensor 3117, only the test load (torque load) is applied, so The test load can be detected with high precision.

在轉矩感測器3117之一端側的圓筒面上形成有複數個滑動 環3119a。另外，在活動板3111上，以從外周側包圍滑動環3119a之方式固定有電刷保持框架3119c。在電刷保持框架3119c之內周安裝有分別與對應之滑動環3119a接觸的複數個電刷3119b。在伺服馬達單元150驅動，而轉矩感測器3117轉動之狀態下，電刷3119b係與滑動環3119a保持接觸，並在滑動環3119a上滑動。轉矩感測器3117之輸出信號以輸出至滑動環3119a的方式構成，並經由與滑動環3119a接觸之電刷3119b，可將轉矩感測器3117之輸出信號取出至第一驅動部3110的外部。 A plurality of sliding surfaces are formed on a cylindrical surface on one end side of the torque sensor 3117 Ring 3119a. Further, on the movable panel 3111, the brush holding frame 3119c is fixed so as to surround the slide ring 3119a from the outer peripheral side. A plurality of brushes 3119b respectively contacting the corresponding slip ring 3119a are attached to the inner periphery of the brush holding frame 3119c. In a state where the servo motor unit 150 is driven and the torque sensor 3117 is rotated, the brush 3119b is kept in contact with the slide ring 3119a and slides on the slide ring 3119a. The output signal of the torque sensor 3117 is configured to be output to the sliding ring 3119a, and the output signal of the torque sensor 3117 can be taken out to the first driving portion 3110 via the brush 3119b in contact with the sliding ring 3119a. external.

第二驅動部3120(第二十六圖)之構造與第一驅動部3110 相同，驅動伺服馬達單元150時夾盤裝置3126會轉動。在夾盤裝置3126上固定受測體T1之另一端部(轉動軸之一個)。另外，受測體T1之外殼固定於支撐框架S。 The configuration of the second driving portion 3120 (the twenty-sixth drawing) and the first driving portion 3110 Similarly, the chuck device 3126 rotates when the servo motor unit 150 is driven. The other end portion (one of the rotating shafts) of the subject T1 is fixed to the chuck device 3126. Further, the outer casing of the subject T1 is fixed to the support frame S.

本實施形態之扭力測試裝置3100係在將FR車用之傳動單元 的受測體T1之輸出軸O與輸入軸I(引擎側)分別固定於第一驅動部3110與第二驅動部3120的夾盤裝置3116、3126之狀態下，藉由伺服馬達單元150、150同步轉動驅動，並且使兩夾盤裝置3116、3126之轉數(或轉動之相位)保持差異，藉此對受測體T1施加扭力載荷者。例如，使第二驅動部3120之夾盤裝置3126等速轉動驅動，並且以第一驅動部3110之轉矩感測器3117檢測的轉矩按照指定之波形而變動的方式轉動驅動夾盤裝置3116，對傳動單元之受測體T1施加周期性變動的轉矩。 The torque testing device 3100 of the present embodiment is a transmission unit for an FR vehicle. The output shaft O and the input shaft I (engine side) of the subject T1 are fixed to the chuck devices 3116 and 3126 of the first driving unit 3110 and the second driving unit 3120, respectively, by the servo motor units 150 and 150. The rotational drive is synchronously rotated, and the number of revolutions (or the phase of rotation) of the two chuck devices 3116, 3126 is kept different, thereby applying a torsional load to the subject T1. For example, the chuck device 3126 of the second driving unit 3120 is rotationally driven at a constant speed, and the torque detected by the torque sensor 3117 of the first driving unit 3110 is rotationally driven in accordance with the specified waveform to drive the chuck device 3116. A periodically varying torque is applied to the subject T1 of the transmission unit.

如此，本實施形態之扭力測試裝置3100，係因為可藉由伺服 馬達單元150、150精密驅動傳動單元之輸入軸I與輸出軸O兩者，所以藉由使傳動單元轉動驅動，並對傳動單元之各軸施加變動轉矩，可在接近汽車實際行駛狀態的條件下進行測試。 Thus, the torque testing device 3100 of the present embodiment is because of the servo The motor units 150 and 150 precisely drive both the input shaft I and the output shaft O of the transmission unit. Therefore, by driving the transmission unit to rotate and applying a varying torque to each shaft of the transmission unit, the condition of approaching the actual running state of the vehicle can be obtained. Test it down.

如傳動單元所示，經由齒輪等連結有輸入軸I與輸出軸O之 裝置進行轉動扭力測試時，施加於輸入軸I與輸出軸O之轉矩的大小並非一致。因而，為了更正確掌握扭力測試時受測體T1的狀態，宜可在輸入軸I側與輸出軸O側個別地計測轉矩。本實施形態中，如上述，因為在第一驅動部3110與第二驅動部3120兩者設有轉矩感測器，所以可在傳動單元(受測體T1)之輸入軸I側與輸出軸O側個別地計測轉矩。 As shown in the transmission unit, the input shaft I and the output shaft O are coupled via a gear or the like. When the device performs the rotational torque test, the magnitude of the torque applied to the input shaft I and the output shaft O does not coincide. Therefore, in order to more accurately grasp the state of the subject T1 at the time of the torque test, it is preferable to measure the torque individually on the input shaft I side and the output shaft O side. In the present embodiment, as described above, since the torque sensor is provided in both the first drive unit 3110 and the second drive unit 3120, the input shaft I side and the output shaft of the transmission unit (subject T1) can be provided. The torque is measured individually on the O side.

另外，上述之例係等速轉動驅動傳動單元之輸入軸I側，並 在輸出軸O側賦予轉矩而構成，不過本發明並非限定於上述之例者，亦即，亦可構成等速轉動驅動傳動單元之輸出軸O側，並且在輸入軸I側施加變動轉矩。或是，亦可構成使傳動單元之輸入軸I側與輸出軸O側兩者分別以變動之轉數轉動驅動。此外，亦可構成不控制轉數，而僅控制各軸之轉矩。 此外，亦可構成使轉矩及轉數按照指定之波形變動。轉矩及轉數例如可按照函數產生器產生之任意波形而變動。此外，亦可依據實際行駛測試時所計測的轉矩及轉數的波形資料，來控制受測體T1各軸之轉矩及轉數。 In addition, the above example is a constant speed rotation drive drive unit input shaft I side, and The torque is applied to the output shaft O side. However, the present invention is not limited to the above-described example, that is, the output shaft O side of the constant-speed rotational drive transmission unit may be formed, and the variable torque may be applied to the input shaft I side. . Alternatively, the input shaft I side and the output shaft O side of the transmission unit may be rotationally driven at a varying number of revolutions. In addition, it is also possible to control the torque of each axis without controlling the number of revolutions. In addition, it is also possible to configure the torque and the number of revolutions to vary according to a specified waveform. The torque and the number of revolutions can be varied, for example, according to an arbitrary waveform generated by the function generator. In addition, the torque and the number of revolutions of each axis of the test object T1 can be controlled according to the waveform data of the torque and the number of revolutions measured during the actual driving test.

本實施形態之扭力測試裝置3100係為了可對應於各種尺寸 之傳動單元，形成可調整夾盤裝置3116與3126之間隔。具體而言，第一驅動部3110之活動板3111藉由活動板驅動機構(無圖示)，可對基座3110b在夾盤裝置3116之轉動軸方向(第二十六圖中左右方向)移動。另外，進行轉動扭力測試中，活動板3111係藉由無圖示之鎖定機構而強固地固定於基座 3110b上。此外，第二驅動部3120亦具備與第一驅動部3110同樣之活動板驅動機構。 The torque testing device 3100 of the present embodiment is designed to correspond to various sizes. The drive unit forms an interval between the adjustable chuck devices 3116 and 3126. Specifically, the movable plate 3111 of the first driving unit 3110 can move the base 3110b in the rotational axis direction of the chuck device 3116 (the horizontal direction in the twenty-sixth drawing) by the movable plate driving mechanism (not shown). . In addition, in the rotational torque test, the movable plate 3111 is strongly fixed to the base by a locking mechanism (not shown). On 3110b. Further, the second drive unit 3120 also includes a movable panel drive mechanism similar to that of the first drive unit 3110.

以上說明之本發明第十三實施形態的扭力測試裝置3100，係 將FR車用傳動單元作為對象進行轉動扭力測試者，不過，本發明並非限定於上述第十三實施形態之基本例的構成者，用於進行其他動力傳達機構之轉動扭力測試的裝置也包含於本發明。以下說明之本發明第十三實施形態的第一、第二及第三變形例，係分別適於FF車用之傳動單元、差速齒輪單元、及4WD車用傳送單元之測試的扭力測試裝置之構成例。 The torque testing device 3100 of the thirteenth embodiment of the present invention described above is The FR vehicle transmission unit is used as a target for the rotational torque test.

Further, the torque test device 3200 is provided with a control unit C3a that comprehensively controls its operation. Since the configurations of the first drive unit 3210, the second drive unit 3220, and the third drive unit 3230 are the same as those of the first drive unit 3110 and the second drive unit 3120 of the basic example of the thirteenth embodiment, the description is omitted.

Inconsistent. Further, the torque applied to the left output shaft OL and the right output shaft OR is not limited to be uniform. Therefore, in order to more accurately grasp the state of the subject T2 during the torque test, it is preferable to individually measure the torque applied to the input shaft I, the left output shaft OL, and the right output shaft OR. In the present modification, since the first drive unit 3210, the second drive unit 3220, and the third drive unit 3230 are all provided with torque sensors, the respective inputs to the transmission unit (subject T2) can be separately measured.

藉由本變形例之扭力測試裝置3300進行受測體T3的轉動扭 力測試時，例如藉由第一驅動部3310以指定轉數驅動輸入軸I，同時藉由第二驅動部3320及第三驅動部3330，以分別對左側輸出軸OL及右側輸出軸OR施加轉矩之方式驅動。 The torsion testing device 3300 of the present modification performs the rotational twist of the subject T3 In the force test, for example, the first drive unit 3310 drives the input shaft I at a predetermined number of revolutions, and the second drive unit 3320 and the third drive unit 3330 respectively apply a rotation to the left output shaft OL and the right output shaft OR. The mode of the moment is driven.

如上述，藉由透過控制第一驅動部3310、第二驅動部3320 及第三驅動部3330，而轉動驅動受測體T3之各軸，並且對受測體T3之各軸施加變動轉矩，藉此可在接近實際使用狀態之條件下進行測試。 As described above, the first driving unit 3310 and the second driving unit 3320 are controlled by transmission. The third drive unit 3330 rotates and drives each axis of the subject T3, and applies a varying torque to each axis of the subject T3, whereby the test can be performed under conditions close to the actual use state.

差速齒輪單元亦與傳動單元同樣地，係經由齒輪等連結輸入 軸I與左側輸出軸OL及右側輸出軸OR之裝置，且進行其轉動扭力測試時，施加於輸入軸I之轉矩的大小與施加於左側輸出軸OL及右側輸出軸OR的轉矩大小不一致。此外，施加於左側輸出軸OL與右側輸出軸OR之轉矩大小亦不限於須一致。因而，為了更正確掌握扭力測試時受測體T3之狀態，應可個別計測輸入軸I、左側輸出軸OL及右側輸出軸OR之轉矩。本變形例中， 因為第一驅動部3310、第二驅動部3320、第三驅動部3330全部設有轉矩感測器，所以可各別計測分別施加於差速齒輪單元(受測體T3)之輸入軸I、左側輸出軸OL及右側輸出軸OR的轉矩。 Similarly to the transmission unit, the differential gear unit is connected via a gear or the like. When the shaft I is connected to the left output shaft OL and the right output shaft OR, and the rotational torque test is performed, the magnitude of the torque applied to the input shaft I does not match the magnitude of the torque applied to the left output shaft OL and the right output shaft OR. . Further, the magnitude of the torque applied to the left output shaft OL and the right output shaft OR is not limited to be uniform. Therefore, in order to more accurately grasp the state of the subject T3 during the torque test, the torque of the input shaft I, the left output shaft OL, and the right output shaft OR should be individually measured. In this modification, Since the first drive unit 3310, the second drive unit 3320, and the third drive unit 3330 are all provided with torque sensors, the input shafts I respectively applied to the differential gear unit (subject T3) can be separately measured, The torque of the left output shaft OL and the right output shaft OR.

另外，亦可構成以輸入軸I之轉數與左側輸出軸OL及右側輸 出軸OR之轉數描繪相同波形的方式控制第二驅動部3320及第三驅動部3330，或是亦可構成以兩者描繪不同(例如與輸入軸I之速度差成為反相位之)波形的方式控制第二驅動部3320及第三驅動部3330。 In addition, it can also be configured to input the number of revolutions of the axis I and the left output shaft OL and the right side. The second drive unit 3320 and the third drive unit 3330 are controlled such that the number of revolutions of the output shaft OR is the same waveform, or a waveform that is different in drawing (for example, the speed difference from the input axis I is opposite) may be configured. The second drive unit 3320 and the third drive unit 3330 are controlled in a manner.

此外，亦可構成等速轉動驅動左側輸出軸OL與右側輸出軸 OR，速度以一定周期變動之方式驅動輸入軸I。或是，亦可構成將輸入軸I、左側輸出軸OL及右側輸出軸OR之全部以轉數變動的方式來驅動。 In addition, it can also constitute a constant speed rotation drive left output shaft OL and right output shaft OR, the speed drives the input shaft I in a manner that varies in a certain period. Alternatively, the input shaft I, the left output shaft OL, and the right output shaft OR may be driven to vary in number of revolutions.

(第十四實施形態) (Fourteenth embodiment)

上述第一至第十三實施形態，係與具有1個輸出軸之伺服馬達150B連結使用本發明實施形態之雙軸輸出伺服馬達150A，不過如其次說明之本發明第十四實施形態，亦可單獨使用伺服馬達150B。 In the first to thirteenth embodiments, the two-axis output servo motor 150A according to the embodiment of the present invention is connected to the servo motor 150B having one output shaft. However, as described in the fourteenth embodiment of the present invention, The servo motor 150B is used alone.

第三十一圖係本發明第十四實施形態之扭力測試裝置4000的側視圖。扭力測試裝置4000係僅使用1台雙軸輸出伺服馬達150A，可同時進行2個受測體T3a、T3b之轉動扭力測試的裝置。扭力測試裝置4000具備固定基座4100、驅動部4200、第一反作用力部4400A、第二反作用力部4400B及控制單元C4。 A thirty-first drawing is a side view of a torque testing device 4000 according to a fourteenth embodiment of the present invention. The torque test device 4000 is a device that can simultaneously perform rotational torque testing of two test bodies T3a and T3b using only one dual-axis output servo motor 150A. The torque test device 4000 includes a fixed base 4100, a drive unit 4200, a first reaction force portion 4400A, a second reaction force portion 4400B, and a control unit C4.

第三十二圖係驅動部4200之放大圖。驅動部4200具備雙軸輸出伺服馬達150A、及一對驅動傳達部4200A、4200B。雙軸輸出伺服馬達150A連接於控制單元C4，而藉由控制單元C4來控制驅動。驅動傳達部4200A、4200B分別將雙軸輸出伺服馬達150A之第一輸出軸150A2a、第二輸出軸150A2b的轉動減速，並傳達至受測體T3a、T3b之輸入軸。因為驅動傳達部4200A與驅動傳達部4200B係相同構成，所以僅說明一方驅動傳達部4200A 之詳細構成。 The thirty-second diagram is an enlarged view of the driving unit 4200. The drive unit 4200 includes a two-axis output servo motor 150A and a pair of drive transmission units 4200A and 4200B. The two-axis output servo motor 150A is connected to the control unit C4, and the drive is controlled by the control unit C4. The drive transmitting units 4200A and 4200B decelerate the rotation of the first output shaft 150A2a and the second output shaft 150A2b of the two-axis output servo motor 150A, respectively, and transmit them to the input axes of the subjects T3a and T3b. Since the drive transmission unit 4200A has the same configuration as the drive communication unit 4200B, only one drive transmission unit 4200A will be described. The detailed composition.

驅動傳達部4200A具備框架4210、減速機4220、滑輪4230、 定時皮帶4240、旋轉編碼器4250及夾盤裝置4260。框架4210係安裝於固定基座4100上之角(L型材)狀的框架，且具備水平配置於固定基座4100上之平板的底板4212、從底板4212之上面一端部直立的平板之縱板4214、與垂直連接於底板4212及縱板4214的一對肋板4216。底板4212、縱板4214及肋板4216藉由焊接而相互連接。縱板4214係與雙軸輸出伺服馬達150A之第一輸出軸150A2a垂直配置，並具有與第一輸出軸150A2a同軸形成之開口部4214a。縱板4214之開口部4214a中***減速機4220而固定。 The drive transmission unit 4200A includes a frame 4210, a reducer 4220, a pulley 4230, and Timing belt 4240, rotary encoder 4250 and chuck device 4260. The frame 4210 is a frame having an angle (L-shaped) shape attached to the fixed base 4100, and has a bottom plate 4212 of a flat plate horizontally disposed on the fixed base 4100, and a vertical plate 4214 of a flat plate standing up from an upper end portion of the bottom plate 4212. And a pair of ribs 4216 connected perpendicularly to the bottom plate 4212 and the vertical plate 4214. The bottom plate 4122, the vertical plate 4214, and the ribs 4216 are connected to each other by welding. The vertical plate 4214 is disposed perpendicular to the first output shaft 150A2a of the biaxial output servo motor 150A, and has an opening portion 4214a formed coaxially with the first output shaft 150A2a. A reduction gear 4220 is inserted into the opening 4214a of the vertical plate 4214 and fixed.

在減速機4220之輸入側凸緣板4224上，以螺栓安裝有雙軸輸 出伺服馬達150A之第一托架150A3。第一托架150A3除了安裝座面(第三十一圖之右側面)之外，亦藉由設於其下面之塞孔150A3t，經由補強板4212而固定於輸入側凸緣板4224。藉此，以高剛性連結減速機4220之輸入側凸緣板4224與雙軸輸出伺服馬達150A之第一托架150A3，可進行高精度測試。 On the input side flange plate 4224 of the reducer 4220, a double shaft transmission is bolted The first bracket 150A3 of the servo motor 150A is taken out. The first bracket 150A3 is fixed to the input side flange plate 4224 via the reinforcing plate 4212 by a mounting hole 150A3t provided in the lower surface thereof in addition to the mounting surface (the right side surface of the 31st drawing). Thereby, the input side flange plate 4224 of the speed reducer 4220 and the first bracket 150A3 of the two-axis output servo motor 150A are coupled with high rigidity, and high-precision testing can be performed.

雙軸輸出伺服馬達150A之第一輸出軸150A2a係與減速機 4220之輸入軸(無圖示)連結。此外，在減速機4220之輸出軸4228的前端部安裝有夾盤裝置4260。夾盤裝置4260上安裝有受測體T3a之輸入軸。雙軸輸出伺服馬達150A之第一輸出軸150A2a的轉動，係藉由減速機4220減速而增大轉矩後，經由夾盤裝置4260傳達至受測體T3a之輸入軸。 The first output shaft 150A2a of the dual-axis output servo motor 150A is connected to the reducer The 4220 input shaft (not shown) is connected. Further, a chuck device 4260 is attached to the front end portion of the output shaft 4228 of the speed reducer 4220. An input shaft of the subject T3a is attached to the chuck device 4260. The rotation of the first output shaft 150A2a of the two-axis output servo motor 150A is reduced by the reduction of the speed reducer 4220, and then transmitted to the input shaft of the subject T3a via the chuck device 4260.

減速機4220中設有加油杯4222，並以潤滑油填充減速機4220 之內部空間，可使構成減速機4220之各齒輪隨時完全浸入潤滑油。扭力測試時，因為係對受測體施加常用區域的往復扭力載荷，所以扭轉受測體之 角度至多為數10°程度，即使減速機之輸入軸反覆轉動之振幅也往往不及1周(360°)。藉由以潤滑油填充減速機4220之內部空間，即使在此種使用形態下，仍可防止構成減速機之齒輪機構缺油膜，並且提高潤滑油之散熱效果，有效防止齒面之燒結。 A refueling cup 4222 is disposed in the reducer 4220, and the reducer 4220 is filled with lubricating oil. The internal space allows the gears constituting the speed reducer 4220 to be completely immersed in the lubricating oil at any time. In the torque test, since the reciprocating torque load of the common region is applied to the test body, the object to be tested is twisted. The angle is at most 10 degrees, even if the amplitude of the input shaft of the reducer is reversed, the amplitude is often less than one week (360°). By filling the internal space of the reduction gear 4220 with lubricating oil, even in such a use mode, the oil-deficient film of the gear mechanism constituting the reduction gear can be prevented, and the heat dissipation effect of the lubricating oil can be improved, and the sintering of the tooth surface can be effectively prevented.

在輸出軸4228之外周設有滑輪4230。此外，在框架4210之縱 板4214上，並在減速機4220之下方配置旋轉編碼器4250。在安裝於旋轉編碼器4250之輸入軸的滑輪4252與安裝於減速機4220之輸出軸4228的滑輪4230上捲掛定時皮帶4240，減速機4220之輸出軸4228的轉動係經由定時皮帶4240傳達至旋轉編碼器4250以進行檢測。旋轉編碼器4250連接有控制單元C4，並將顯示旋轉編碼器4250所檢測之轉動的信號傳送至控制單元C4。 A pulley 4230 is provided on the outer circumference of the output shaft 4228. In addition, in the longitudinal direction of the frame 4210 On the plate 4214, a rotary encoder 4250 is disposed below the speed reducer 4220. The timing belt 4240 is wound around the pulley 4252 mounted on the input shaft of the rotary encoder 4250 and the pulley 4230 mounted on the output shaft 4228 of the reduction gear 4220, and the rotation of the output shaft 4228 of the reduction gear 4220 is transmitted to the rotation via the timing belt 4240. Encoder 4250 is used for detection. The rotary encoder 4250 is connected to the control unit C4 and transmits a signal indicating the rotation detected by the rotary encoder 4250 to the control unit C4.

其次說明第一反作用力部4400A。另外，關於第二反作用力部4400B，因為其構成與第一反作用力部4400A相同，所以省略詳細之說明。 Next, the first reaction force portion 4400A will be described. In addition, since the second reaction force portion 4400B has the same configuration as the first reaction force portion 4400A, detailed description thereof will be omitted.

第一反作用力部4400A具備框架4410、轉矩感測器4420、心軸4440、軸承部4460及夾盤裝置4480。框架4410係以螺栓B安裝於固定基座4100上的角(L型材)狀之框架，且具備水平配置於固定基座4100上之底盤部4412、從底盤部4412之上面一端部(第三十一圖之左端部)直立的平板之縱板2414、與垂直連接於底盤部4412及縱板2414之一對肋板2416。底盤部4412、縱板2414及肋板2416藉由焊接而相互連接。此外，軸承部4460在比縱板2414及肋板2416靠近驅動部4200側，以螺栓B固定於底盤部4412上。 The first reaction force portion 4400A includes a frame 4410, a torque sensor 4420, a spindle 4440, a bearing portion 4460, and a chuck device 4480. The frame 4410 is a frame having an angle (L-shaped) in which the bolts B are attached to the fixed base 4100, and has a chassis portion 4412 horizontally disposed on the fixed base 4100, and an upper end portion from the upper portion of the chassis portion 4412 (thirtieth The left end of the figure is a vertical plate 2414 of the upright plate and a pair of ribs 2416 perpendicularly connected to the chassis portion 4412 and the vertical plate 2414. The chassis portion 4412, the vertical plate 2414, and the ribs 2416 are connected to each other by soldering. Further, the bearing portion 4460 is closer to the driving portion 4200 than the vertical plate 2414 and the rib 2416, and is fixed to the chassis portion 4412 with a bolt B.

固定基座4100具備使第一反作用力部4400A向雙軸輸出伺服馬達150A之第一輸出軸150A2a的方向平滑移動之第一反作用力部移動機構(無圖示)，在底盤部4412上旋鬆固定於固定基座4100之螺栓B的狀態下， 使第一反作用力部移動機構工作，可向第一輸出軸150A2a之方向平滑地移動第一反作用力部4400A。另外，固定基座4100亦具備使第二反作用力部4400B向雙軸輸出伺服馬達150A之第二輸出軸150A2b的方向平滑移動之第二反作用力部移動機構(無圖示)。 The fixed base 4100 includes a first reaction force portion moving mechanism (not shown) that smoothly moves the first reaction force portion 4400A in the direction of the first output shaft 150A2a of the biaxial output servo motor 150A, and is loosened on the chassis portion 4412. Fixed to the state of the bolt B of the fixed base 4100, When the first reaction force portion moving mechanism is operated, the first reaction force portion 4400A can be smoothly moved in the direction of the first output shaft 150A2a. Further, the fixed base 4100 also includes a second reaction force portion moving mechanism (not shown) that smoothly moves the second reaction force portion 4400B in the direction of the second output shaft 150A2b of the biaxial output servo motor 150A.

轉矩感測器4420、心軸4440、軸承部4460及夾盤裝置4480 係分別與雙軸輸出伺服馬達150A之第一輸出軸150A2a同軸配置。在框架4410之縱板2414上固定有轉矩感測器4420之一端部(第三十一圖之左端部)。此外，在轉矩感測器4420之另一端部固定有心軸4440之一端部(第三十一圖之左端部)，在心軸4440之另一端部安裝有夾盤裝置4480。夾盤裝置4480上安裝有受測體T3a之輸出軸。 Torque sensor 4420, spindle 4440, bearing portion 4460, and chuck device 4480 They are disposed coaxially with the first output shaft 150A2a of the dual-axis output servo motor 150A, respectively. One end of the torque sensor 4420 (the left end of the thirty-first figure) is fixed to the vertical plate 2414 of the frame 4410. Further, one end of the spindle 4440 (the left end of the 31st drawing) is fixed to the other end of the torque sensor 4420, and a chuck device 4480 is attached to the other end of the spindle 4440. An output shaft of the subject T3a is attached to the chuck device 4480.

受測體T3a之輸出軸的轉矩係經由夾盤裝置4480及心軸 4440而傳達至轉矩感測器4420進行檢測。轉矩感測器4420連接於控制單元C4，顯示轉矩感測器4420所檢測之受測體T3a的輸出軸轉矩之信號傳送至控制單元C4進行處理。 The torque of the output shaft of the test body T3a is via the chuck device 4480 and the spindle 4440 is communicated to torque sensor 4420 for detection. The torque sensor 4420 is connected to the control unit C4, and the signal indicating the output shaft torque of the subject T3a detected by the torque sensor 4420 is transmitted to the control unit C4 for processing.

此外，心軸4440在另一端部(夾盤裝置4480側之端部)的附 近藉由軸承部4460自由轉動地支撐。因此，因為轉矩感測器4420與心軸4440係藉由縱板2414與軸承部4460兩者支撐，所以防止藉由對轉矩感測器4420施加大的彎曲力矩，造成轉矩感測器4420之檢測誤差變大。 Further, the attachment of the mandrel 4440 at the other end (the end of the chuck device 4480 side) It is supported by the bearing portion 4460 so as to be freely rotatable. Therefore, since the torque sensor 4420 and the spindle 4440 are supported by both the vertical plate 2414 and the bearing portion 4460, the torque sensor is prevented from being applied by applying a large bending moment to the torque sensor 4420. The detection error of the 4420 becomes larger.

使用上述構成之扭力測試裝置4000進行轉動扭力測試時，如 上述，係在驅動傳達部4200A之夾盤裝置4260上安裝受測體T3a之輸入軸，並在第一反作用力部4400A之夾盤裝置4480上安裝受測體T3a之輸出軸。同樣地，在驅動傳達部4200B之夾盤裝置4260上安裝受測體T3b之輸入軸，並 在第二反作用力部4400B之夾盤裝置4480上安裝受測體T3b之輸出軸。在該狀態下驅動雙軸輸出伺服馬達150A時，第一輸出軸150A2a與第二輸出軸150A2b係以相同相位轉動，驅動傳達部4200A與驅動傳達部4200B之夾盤裝置4260亦以相同相位轉動。藉此，在受測體T3a與T3b上施加相同扭力量，亦即係對受測體T3a與T3b進行相同條件之扭力測試。 When the rotational torque test is performed using the torque test device 4000 constructed as described above, As described above, the input shaft of the subject T3a is attached to the chuck device 4260 of the drive transmitting portion 4200A, and the output shaft of the subject T3a is attached to the chuck device 4480 of the first reaction portion 4400A. Similarly, the input shaft of the subject T3b is mounted on the chuck device 4260 of the drive transmitting portion 4200B, and The output shaft of the subject T3b is attached to the chuck device 4480 of the second reaction force portion 4400B. When the two-axis output servo motor 150A is driven in this state, the first output shaft 150A2a and the second output shaft 150A2b rotate in the same phase, and the chucking device 4260 that drives the transmission portion 4200A and the drive transmission portion 4200B also rotates in the same phase. Thereby, the same torsion force is applied to the subject T3a and T3b, that is, the torque test of the subject T3a and T3b under the same conditions is performed.

根據上述第十四實施形態之構成，因為可使用1台伺服馬達 及控制單元C4同時進行2個受測體T3a、T3b的扭力測試(疲勞測試)，所以可有效率地進行測試。 According to the configuration of the fourteenth embodiment described above, since one servo motor can be used The control unit C4 simultaneously performs the torque test (fatigue test) of the two test bodies T3a and T3b, so that the test can be performed efficiently.

此外，例如藉由設置進給螺桿機構等線性變換器來取代驅動 傳達部4200A、4200B，可形成對2個受測體T3a、T3b反覆賦予壓縮力與拉伸力(或是，對受測體T3a、T3b之一方賦予壓縮力，對另一方賦予拉伸力)的拉伸、壓縮測試裝置。藉由該構成，可同時對2個受測體T3a、T3b反覆進行伸縮測試(或是對受測體T3a進行拉伸測試與對受測體T3b進行壓縮測試)。此外，此時藉由不用第一反作用力部4400A、第二反作用力部4400B，可同時進行2個受測體T3a、T3b之振動測試。 In addition, the drive is replaced by, for example, a linear converter such as a feed screw mechanism. The transmitting units 4200A and 4200B can form a compressive force and a tensile force against the two subject T3a and T3b (or a compressive force is applied to one of the subjects T3a and T3b, and a tensile force is applied to the other). Stretching, compression test device. According to this configuration, the two test bodies T3a and T3b can be subjected to the expansion and contraction test at the same time (or the tensile test of the test object T3a and the compression test of the test object T3b). Further, at this time, the vibration test of the two test bodies T3a and T3b can be simultaneously performed by not using the first reaction force portion 4400A and the second reaction force portion 4400B.

第三十三圖係本發明第十五實施形態之振動測試裝置(勵磁裝置)5000的上視圖。本實施形態之振動測試裝置5000係將振動測試對象 之工件固定於平台5100上，使用第一、第二、第三致動器5200、5300、5400將平台5100及其上之工件在正交3軸方向勵磁。另外，以下之說明中，將第一致動器5200勵磁平台5100之方向(第三十三圖之上下方向)定義為X軸方向，將第二致動器5300勵磁平台5100之方向(第三十三圖之左右方向)定義為Y軸方向，將第三致動器5400勵磁平台之方向，亦即垂直方向(第三十三圖中，與紙面垂直之方向)定義為Z軸方向。 A thirty-third drawing is a top view of a vibration testing device (excitation device) 5000 according to a fifteenth embodiment of the present invention. The vibration test device 5000 of the present embodiment is a vibration test object The workpiece is fixed to the platform 5100, and the first and second and third actuators 5200, 5300, and 5400 are used to excite the platform 5100 and the workpiece thereon in the orthogonal three-axis direction. In addition, in the following description, the direction of the excitation stage 5100 of the first actuator 5200 (the upper and lower directions of the thirty-third diagram) is defined as the X-axis direction, and the direction of the second actuator 5300 is excited by the platform 5100 ( The left-right direction of the thirty-third figure is defined as the Y-axis direction, and the direction of the excitation platform of the third actuator 5400, that is, the vertical direction (the direction perpendicular to the paper surface in the thirty-third figure) is defined as the Z-axis. direction.

第三十八圖係本發明實施形態之振動測試裝置之控制系統 方塊圖。在第一、第二、第三致動器5200、5300、5400中分別設有振動感測器5220、5320、5420。依據此等振動感測器之輸出，控制單元C5藉由反饋控制第一、第二、第三致動器5200、5300、5400(具體而言，係伺服馬達單元150X、150Y、150Z)，可以指定之振幅及頻率(此等參數通常作為時間函數而設定)勵磁平台5100及安裝於其上之工件。伺服馬達單元150X、150Y、150Z係與第一實施形態之伺服馬達單元150相同者。 38 is a control system of a vibration testing device according to an embodiment of the present invention Block diagram. Vibration sensors 5220, 5320, 5420 are provided in the first, second, and third actuators 5200, 5300, and 5400, respectively. According to the output of the vibration sensors, the control unit C5 controls the first, second, and third actuators 5200, 5300, and 5400 (specifically, the servo motor units 150X, 150Y, and 150Z) by feedback. The specified amplitude and frequency (these parameters are typically set as a function of time) are the excitation platform 5100 and the workpiece mounted thereon. The servo motor units 150X, 150Y, and 150Z are the same as the servo motor unit 150 of the first embodiment.

第一、第二、第三致動器5200、5300、5400係構成分別在基 板5202、5302、5402上安裝了馬達及動力傳達構件等。該基板5202、5302、5402藉由無圖示之螺栓而固定於裝置基座5002上。 The first, second, and third actuators 5200, 5300, and 5400 are respectively configured A motor, a power transmission member, and the like are attached to the boards 5202, 5302, and 5402. The substrates 5202, 5302, and 5402 are fixed to the device base 5002 by bolts (not shown).

此外，在裝置基座5002上，於接近基板5202、5302、5402 之複數個位置配置有調整器A。調整器A具有以螺栓AB固定於裝置基座5002的陰螺紋部A1、及旋入該陰螺紋部A1之陽螺紋部A2。陽螺紋部A2係在圓筒面上形成有螺紋牙之圓柱狀構件，且藉由使陽螺紋部A2結合於形成於陰螺紋部A1的螺紋孔而轉動，可使陽螺紋部A2對於對應之基板進退。陽螺紋部A2之一端部(對於對應的基板近方位之側)形成概略球面狀，藉由使該突 出部與對應之基板的側面抵接，可進行基板位置之微調整。此外，在陽螺紋部A2之另一端部(對於對應的基板遠方位之側)形成有無圖示之六角扳手用的六角孔。此外，一旦固定基板5202、5302、5402後，即將螺帽A3安裝於陽螺紋部A2上，以避免陽螺紋部A2因藉由振動測試而從基板傳達至調整器A之振動等造成鬆脫。螺帽A3係以其一端面抵接於陰螺紋部A1之方式安裝，從該狀態旋入螺帽A3而壓入陰螺紋部A1，使軸力作用於陽螺紋部A2與陰螺紋部A1，藉由該軸力在陽螺紋部A2與陰螺紋部A1之螺紋牙產生的摩擦力，避免陰螺紋部A1從陽螺紋部A2鬆脫。 In addition, on the device base 5002, near the substrate 5202, 5302, 5402 Regulator A is configured at a plurality of positions. The adjuster A has a female screw portion A1 fixed to the device base 5002 with a bolt AB, and a male screw portion A2 screwed into the female screw portion A1. The male screw portion A2 is a cylindrical member in which a thread is formed on a cylindrical surface, and the male screw portion A2 is rotated by being coupled to a screw hole formed in the female screw portion A1, so that the male screw portion A2 can be correspondingly The substrate advances and retreats. One end of the male thread portion A2 (on the side of the corresponding substrate near the azimuth) forms a substantially spherical shape by causing the protrusion The output portion is in contact with the side surface of the corresponding substrate, and the position of the substrate can be finely adjusted. Further, a hexagonal hole for a hexagonal wrench (not shown) is formed at the other end portion of the male screw portion A2 (on the side of the distal direction of the corresponding substrate). Further, once the substrates 5202, 5302, and 5402 are fixed, the nut A3 is attached to the male screw portion A2 to prevent the male screw portion A2 from being loosened due to vibration or the like transmitted from the substrate to the adjuster A by the vibration test. The nut A3 is attached such that one end surface thereof abuts against the female screw portion A1. From this state, the nut A3 is screwed into the female screw portion A1, and the axial force acts on the male screw portion A2 and the female screw portion A1. By the frictional force generated by the axial force on the thread of the male screw portion A2 and the female screw portion A1, the female screw portion A1 is prevented from being released from the male screw portion A2.

其次，說明第一致動器5200之構成。第三十四圖係從Y軸方 向(第三十三圖從右側向左側)觀看本發明之實施形態的第一致動器5200之側視圖。該測試圖為了顯示內部構造而欠缺一部分。此外，第三十五圖係第一致動器5200之上視圖的一部分欠缺而顯示內部構造者。另外，以下之說明中，將沿著從第一致動器5200朝向平台5100之X軸的方向定義為「X軸正方向」，將沿著從平台5100朝向第一致動器之X軸的方向定義為「X軸負方向」。 Next, the configuration of the first actuator 5200 will be described. The thirty-fourth picture is from the Y-axis A side view of the first actuator 5200 according to the embodiment of the present invention is viewed (from the right side to the left side in the thirty-third diagram). This test chart is missing a part in order to show the internal structure. Further, the thirty-fifth diagram is a part of the upper view of the first actuator 5200 lacking to display the internal constructor. In addition, in the following description, the direction from the first actuator 5200 toward the X-axis of the stage 5100 is defined as the "X-axis positive direction", and will be along the X-axis from the platform 5100 toward the first actuator. The direction is defined as "X-axis negative direction".

如第三十四圖所示，在基板5202上藉由焊接固定有由彼此焊 接之複數個梁5222a與頂板5222b構成的框架5222。此外，用於支撐用於勵磁平台5100(第三十三圖)之驅動機構5210、及用於使驅動機構5210之勵磁運動傳達至平台5100的連結機構5230之支撐機構5240的底板5242，經由無圖示之螺栓而固定於框架5222之頂板5222b上。 As shown in the thirty-fourth figure, soldered to each other by soldering on the substrate 5202 A frame 5222 is formed by a plurality of beams 5222a and a top plate 5222b. Further, a bottom plate 5242 for supporting the drive mechanism 5210 for the excitation stage 5100 (the thirty-third figure) and the support mechanism 5240 for transmitting the excitation motion of the drive mechanism 510 to the connection mechanism 5230 of the platform 5100, It is fixed to the top plate 5222b of the frame 5222 via a bolt (not shown).

驅動機構5210具有伺服馬達單元150X、耦合器5260、軸承 部5216、滾珠螺桿5218及滾珠螺帽5219。耦合器5260係連結伺服馬達單元 150X之驅動軸152X與滾珠螺桿5218者。此外，軸承部5216藉由對支撐機構5240之底板5242垂直焊接而固定之軸承支撐板5244支撐，且可轉動地支撐滾珠螺桿5218。滾珠螺帽5219不在其軸周圍移動而藉由軸承支撐板5244支撐，並與滾珠螺桿5218結合。因而，驅動伺服馬達單元150X時，滾珠螺桿轉動，滾珠螺帽5219在其軸方向(亦即X軸方向)進退。藉由該滾珠螺帽5219之運動經由連結機構5230傳達至平台5100，而在X軸方向驅動平台5100。而後，藉由以短周期切換伺服馬達單元150X之轉動方向來控制伺服馬達單元150X，可以希望之振幅及周期將平台5100勵磁於X軸方向。 The drive mechanism 5210 has a servo motor unit 150X, a coupler 5260, and a bearing The portion 5216, the ball screw 5218, and the ball nut 5219. Coupler 5260 is coupled to the servo motor unit 150X drive shaft 152X and ball screw 5218. Further, the bearing portion 5216 is supported by a bearing support plate 5244 fixed to the bottom plate 5242 of the support mechanism 5240 by vertical welding, and rotatably supports the ball screw 5218. The ball nut 5219 does not move around its axis but is supported by the bearing support plate 5244 and is coupled to the ball screw 5218. Therefore, when the servo motor unit 150X is driven, the ball screw rotates, and the ball nut 5219 advances and retreats in the axial direction (that is, the X-axis direction). The movement of the ball nut 5219 is transmitted to the platform 5100 via the coupling mechanism 5230, and the platform 5100 is driven in the X-axis direction. Then, by controlling the servo motor unit 150X by switching the rotational direction of the servo motor unit 150X in a short cycle, the stage 5100 can be excited in the X-axis direction with a desired amplitude and period.

在支撐機構5240之底板5242的上面，馬達支撐板5246與底板5242垂直地焊接。在馬達支撐板5246之一面(X軸負方向側之面)，以驅動軸152X與馬達支撐板5246垂直之方式，懸臂支撐伺服馬達單元150X。在馬達支撐板5246上設有開口部5246a，伺服馬達單元150X之驅動軸152X貫穿該開口部5246a，而在馬達支撐板5246之另一面側與滾珠螺桿5218連結。 Above the bottom plate 5242 of the support mechanism 5240, the motor support plate 5246 is welded perpendicularly to the bottom plate 5242. On one surface of the motor support plate 5246 (the surface on the negative side of the X-axis), the servo motor unit 150X is supported by the cantilever so that the drive shaft 152X is perpendicular to the motor support plate 5246. An opening 5246a is provided in the motor support plate 5246, and the drive shaft 152X of the servo motor unit 150X passes through the opening 5246a, and is coupled to the ball screw 5218 on the other surface side of the motor support plate 5246.

另外，因為伺服馬達單元150X係懸臂支撐於馬達支撐板5246，所以會對馬達支撐板5246特別是在與底板5242之焊接部上施加大的彎曲應力。為了緩和該彎曲應力，而在底板5242與馬達支撐板5246之間設有肋條5248。 In addition, since the servo motor unit 150X is supported by the motor support plate 5246, a large bending stress is applied to the motor support plate 5246, particularly at the welded portion with the bottom plate 5242. To alleviate the bending stress, ribs 5248 are provided between the bottom plate 5242 and the motor support plate 5246.

軸承部5216具有正面組合而組合之一對角接觸球軸承5216a、5216b(在X軸負方向側者係5216a，在X軸正方向側者係5216b)。角接觸球軸承5216a、5216b收納於軸承支撐板5244的中空部裡面。在角接觸球軸承5216b之一面(X軸正方向側之面)設有軸承按壓板5216c，藉由使用螺栓5216d將該軸承按壓板5216c固定於軸承支撐板5244，而將角接觸球軸 承5216b壓入X軸負方向。此外，在滾珠螺桿5218中，在對軸承部5216鄰接於X軸負方向側之圓筒面形成有螺紋部5218a。在該螺紋部5218a中可安裝內周形成有陰螺紋之軸環5217。藉由使軸環5217對滾珠螺桿5218轉動而移動於X軸正方向，角接觸球軸承5216a係壓入X軸正方向。如此，由於角接觸球軸承5216a與5216b係壓入彼此接近之方向，因此兩者彼此密合而將合適之預加載賦予軸承5216a、5216b。 The bearing portion 5216 has a front surface combination and combines one of the diagonal contact ball bearings 5216a and 5216b (in the X-axis negative direction side, the system 5216a, and the X-axis positive direction side, the system 5216b). The angular contact ball bearings 5216a, 5216b are housed inside the hollow portion of the bearing support plate 5244. A bearing pressing plate 5216c is provided on one surface (the surface on the positive X-axis side) of the angular contact ball bearing 5216b, and the bearing pressing plate 5216c is fixed to the bearing supporting plate 5244 by using a bolt 5216d, and the angular contact ball shaft is attached. The 5216b is pressed into the negative direction of the X axis. Further, in the ball screw 5218, a screw portion 5218a is formed on the cylindrical surface of the bearing portion 5216 adjacent to the negative side in the X-axis direction. A collar 5217 having a female thread formed on the inner circumference thereof can be attached to the threaded portion 5218a. The angular contact ball bearing 5216a is pressed into the positive X-axis direction by rotating the collar 5217 against the ball screw 5218 and moving in the positive X-axis direction. Thus, since the angular contact ball bearings 5216a and 5216b are pressed into directions close to each other, the two are brought into close contact with each other to impart appropriate preloading to the bearings 5216a, 5216b.

其次，說明連結部5230之構成。連結部5230具有螺帽導片 (Nut Guide)5232、一對Y軸軌道5234、一對Z軸軌道5235、中間載台5231、一對X軸軌道5237、一對X軸轉子塊5233、及轉子塊安裝構件5238。 Next, the configuration of the connecting portion 5230 will be described. The joint portion 5230 has a nut guide piece (Nut Guide) 5232, a pair of Y-axis rails 5234, a pair of Z-axis rails 5235, an intermediate stage 5231, a pair of X-axis rails 5237, a pair of X-axis rotor blocks 5233, and a rotor block mounting member 5238.

螺帽導片5232固定於滾珠螺帽5219。此外，一對Y軸軌道 5234係一起向Y軸方向伸出之軌道，且在螺帽導片5232之X軸正方向側的端部並列固定於上下方向。此外，一對Z軸軌道5235係一起向Z軸方向伸出的軌道，且在平台5100之X軸負方向側的端部並列固定於Y軸方向。中間載台5231係將與該Y軸軌道5234之各個結合的Y軸轉子塊5231a設於X軸負方向側之面，將與Z軸軌道5235之各個結合的Z軸轉子塊5231b設於X軸正方向側之面的方塊，且對Y軸軌道5234及Z軸軌道5235兩者可滑動地構成。 The nut guide 5232 is fixed to the ball nut 5219. In addition, a pair of Y-axis tracks The 5234 is a rail that projects in the Y-axis direction together, and is fixed in the vertical direction at the end on the positive side of the X-axis of the nut guide 5232. Further, the pair of Z-axis rails 5235 are rails that extend in the Z-axis direction together, and are fixed in the Y-axis direction in parallel at the end portion of the platform 5100 on the negative side in the X-axis direction. The intermediate stage 5231 is provided with a Y-axis rotor block 5231a coupled to each of the Y-axis rails 5234 on the negative X-axis side, and a Z-axis rotor block 5231b coupled to each of the Z-axis rails 5235 is disposed on the X-axis. A square of the surface on the positive side is slidably formed for both the Y-axis rail 5234 and the Z-axis rail 5235.

亦即，中間載台5231對平台5100可在Z軸方向滑動，且對螺 帽導片5232可在Y軸方向滑動。因此，中間載台5231可對平台5100在Y軸方向及Z軸方向滑動。因而，即使平台5100藉由其他致動器5300及/或5400而勵磁於Y軸方向及/或Z軸方向，螺帽導片5232仍不致因此而變位。亦即，因平台5100在Y軸方向及/或Z軸方向之變位產生的彎曲應力不致施加於滾珠螺桿5218或軸承部5216、耦合器5260等。 That is, the intermediate stage 5231 can slide the platform 5100 in the Z-axis direction, and the snail The cap guide 5232 is slidable in the Y-axis direction. Therefore, the intermediate stage 5231 can slide the platform 5100 in the Y-axis direction and the Z-axis direction. Thus, even if the platform 5100 is excited in the Y-axis direction and/or the Z-axis direction by the other actuators 5300 and/or 5400, the nut guide piece 5232 is not displaced thereby. That is, the bending stress generated by the displacement of the stage 5100 in the Y-axis direction and/or the Z-axis direction is not applied to the ball screw 5218 or the bearing portion 5216, the coupler 5260, or the like.

一對X軸軌道5237係一起向X軸方向伸出之軌道，且在支撐 機構5240之底板5242上並列固定於Y軸方向。X軸轉子塊5233與該X軸軌道5237之各個結合，可沿著X軸軌道5237而滑動。轉子塊安裝構件5238係以朝向Y軸方向兩側伸出之方式而固定於螺帽導片5232底面的構件，且X軸轉子塊5233固定於轉子塊安裝構件5238之底部。如此，螺帽導片5232經由轉子塊安裝構件5238及X軸轉子塊5233引導於X軸軌道5237，藉此，可僅在X軸方向移動。 A pair of X-axis rails 5237 are linked together in the direction of the X-axis, and are supported The bottom plate 5242 of the mechanism 5240 is juxtaposed and fixed in the Y-axis direction. The X-axis rotor block 5233 is combined with each of the X-axis rails 5237 to be slidable along the X-axis rail 5237. The rotor block mounting member 5238 is fixed to the bottom surface of the nut guide piece 5232 so as to protrude toward both sides in the Y-axis direction, and the X-axis rotor block 5233 is fixed to the bottom of the rotor block mounting member 5238. In this manner, the nut guide piece 5232 is guided to the X-axis rail 5237 via the rotor block mounting member 5238 and the X-axis rotor block 5233, whereby it can be moved only in the X-axis direction.

如此，因為螺帽導片5232之移動方向僅限制在X軸方向，所 以驅動伺服馬達單元150X而使滾珠螺桿5218轉動時，螺帽導片5232及與該螺帽導片5232結合之平台5100在X軸方向進退。 Thus, since the direction of movement of the nut guide 5232 is limited only in the X-axis direction, When the ball screw 5218 is rotated by driving the servo motor unit 150X, the nut guide piece 5232 and the stage 5100 coupled to the nut guide piece 5232 advance and retreat in the X-axis direction.

在轉子塊安裝構件5238之Y軸方向側的一方側面(第三十四圖中係近端側，在第三十五圖中係右側)5238a配置有位置檢測手段5250。位置檢測手段5250具有以一定間隔並列於X軸方向的3個接近感測器5251、設於轉子塊安裝構件5238之側面5238a的檢測用板5252、及支撐接近感測器5251之感測器支撐板5253。接近感測器5251係可檢測在各個接近感測器之前是否有某物體接近(例如在1毫米以內)的元件。因為轉子塊安裝構件5238之側面5238a與接近感測器5251充分離開，所以接近感測器5251可檢測在各個接近感測器5251之前是否有檢測用板5252。振動測試裝置5000之控制單元C5係例如使用接近感測器5251之檢測結果可反饋控制伺服馬達單元150X(第三十八圖)。 A position detecting means 5250 is disposed on one side surface (the proximal end side in the thirty-fourth figure, the right side in the thirty-fifth figure) 5238a of the rotor block mounting member 5238 on the Y-axis direction side. The position detecting means 5250 has three proximity sensors 5251 arranged in parallel in the X-axis direction at a predetermined interval, a detecting plate 5252 provided on the side surface 5238a of the rotor block mounting member 5238a, and a sensor support supporting the proximity sensor 5251. Board 5253. The proximity sensor 5251 is capable of detecting whether an object is approaching (eg, within 1 millimeter) before each proximity sensor. Since the side 5238a of the rotor block mounting member 5238 is sufficiently separated from the proximity sensor 5251, the proximity sensor 5251 can detect whether there is a detecting plate 5252 before each of the proximity sensors 5251. The control unit C5 of the vibration test apparatus 5000 can feedback-control the servo motor unit 150X (Thirty-eighth figure) using, for example, the detection result of the proximity sensor 5251.

此外，在支撐機構5240之底板5242上，設有從X軸方向兩側夾著而配置X軸轉子塊5233之管制塊5236。該管制塊5236係用於限制螺帽導 片5232之移動範圍者。亦即，驅動伺服馬達單元150X而使螺帽導片5232向X軸正方向繼續移動時，最後配置於X軸正方向側之管制塊5236與轉子塊安裝構件5238接觸，螺帽導片5232無法在X軸正方向過度移動。使螺帽導片5232朝向X軸負方向繼續移動時亦同，配置於X軸負方向側之管制塊5236與轉子塊安裝構件5238接觸，螺帽導片5232無法在X軸負方向過度移動。 Further, on the bottom plate 5242 of the support mechanism 5240, a control block 5236 in which the X-axis rotor block 5233 is disposed to be sandwiched from both sides in the X-axis direction is provided. The control block 5236 is used to limit the nut guide The range of movement of the slice 5232. That is, when the servo motor unit 150X is driven to move the nut guide piece 5232 in the positive X-axis direction, the control block 5236 finally disposed on the positive side of the X-axis is in contact with the rotor block mounting member 5238, and the nut guide 5232 cannot be Excessive movement in the positive direction of the X axis. When the nut guide piece 5232 is continuously moved in the negative X-axis direction, the control block 5236 disposed on the negative side of the X-axis is in contact with the rotor block mounting member 5238, and the nut guide piece 5232 cannot be excessively moved in the negative X-axis direction.

以上說明之第一致動器5200與第二致動器5300除了設置之 方向不同(X軸與Y軸互換)之外，構造相同。因此，關於第二致動器5300省略詳細之說明。 The first actuator 5200 and the second actuator 5300 described above are provided in addition to The structure is the same except that the directions are different (the X axis is interchanged with the Y axis). Therefore, a detailed description is omitted regarding the second actuator 5300.

其次，說明本發明實施形態之第三致動器5400的構成。第三 十六圖係從X軸方向(從第十六圖之下方向上方)觀看平台5100及第三致動器5400的側視圖。該側視圖亦為了顯示內部構造而欠缺一部分。此外，第三十七圖係從Y軸方向(從第三十三圖之左側向右側)觀看本發明實施形態之平台5100及第三致動器5400的側視圖。第三十七圖亦為了顯示內部構造而欠缺一部分。另外，在以下之說明中，係將沿著從第二致動器5300朝向平台5100之Y軸的方向定義為Y軸正方向，將沿著從平台5100朝向第二致動器5300之Y軸的方向定義為Y軸負方向。 Next, the configuration of the third actuator 5400 according to the embodiment of the present invention will be described. third The sixteenth view is a side view of the stage 5100 and the third actuator 5400 viewed from the X-axis direction (upward from the lower side of the sixteenth figure). This side view is also missing a part in order to show the internal structure. Further, in the thirty-seventh embodiment, a side view of the stage 5100 and the third actuator 5400 according to the embodiment of the present invention is viewed from the Y-axis direction (from the left side to the right side of the thirty-third figure). The thirty-seventh figure also lacks a part to show the internal structure. In addition, in the following description, the direction along the Y-axis from the second actuator 5300 toward the platform 5100 is defined as the Y-axis positive direction, and will be along the Y-axis from the platform 5100 toward the second actuator 5300. The direction is defined as the negative direction of the Y axis.

如第三十六圖及第三十七圖所示，在基板5402上設有由垂直 方向伸出之複數個梁5422a、與從上方覆蓋該複數個梁5422a而配置的頂板5422b構成之框架5422。各梁5422a之下端焊接於基板5402之上面，上端焊接於頂板5422b之下面。此外，支撐機構5440之軸承支撐板5442經由無圖示的螺栓而固定於框架5422之頂板5422b上。該軸承支撐板5442係用於支撐將平台5100(第三十三圖)在上下方向勵磁用之驅動機構5410、以及用於將 驅動機構5410之勵磁運動傳達至平台的連結機構5430之構件。 As shown in the thirty-sixth and thirty-seventh figures, the substrate 5402 is provided with a vertical A plurality of beams 5422a extending in the direction and a frame 5422 formed by a top plate 5422b disposed to cover the plurality of beams 5422a from above. The lower end of each of the beams 5422a is welded to the upper surface of the substrate 5402, and the upper end is welded to the lower surface of the top plate 5422b. Further, the bearing support plate 5442 of the support mechanism 5440 is fixed to the top plate 5422b of the frame 5422 via bolts (not shown). The bearing support plate 5442 is for supporting a driving mechanism 5410 for exciting the platform 5100 (the thirty-third figure) in the up and down direction, and for The excitation motion of the drive mechanism 5410 is communicated to the components of the linkage mechanism 5430 of the platform.

驅動機構5410具有伺服馬達單元150Z、耦合器5460、軸承 部5416、滾珠螺桿5418及滾珠螺帽5419。耦合器5460係連結伺服馬達單元150Z之驅動軸152Z與滾珠螺桿5418者。此外，軸承部5416固定於前述之軸承支撐板5442，可轉動地支撐滾珠螺桿5418。滾珠螺帽5419不在其軸周圍移動而藉由軸承支撐板5442支撐，並與滾珠螺桿5418結合。因而，驅動伺服馬達單元150Z時，滾珠螺桿轉動，滾珠螺帽5419在其軸方向(亦即Z軸方向)進退。藉由該滾珠螺帽5419之運動經由連結機構5430而傳達至平台5100，在Z軸方向驅動平台5100。而後，藉由以短周期切換伺服馬達單元150Z之轉動方向來控制伺服馬達單元150Z，可以希望之振幅及周期將平台5100勵磁於Z軸方向(上下方向)。 The drive mechanism 5410 has a servo motor unit 150Z, a coupler 5460, and a bearing The portion 5416, the ball screw 5418, and the ball nut 5419. The coupler 5460 is coupled to the drive shaft 152Z of the servo motor unit 150Z and the ball screw 5418. Further, the bearing portion 5416 is fixed to the aforementioned bearing support plate 5442 to rotatably support the ball screw 5418. The ball nut 5419 does not move around its axis but is supported by the bearing support plate 5442 and is coupled to the ball screw 5418. Therefore, when the servo motor unit 150Z is driven, the ball screw rotates, and the ball nut 5419 advances and retreats in the axial direction (i.e., the Z-axis direction). The movement of the ball nut 5419 is transmitted to the platform 5100 via the coupling mechanism 5430, and the platform 5100 is driven in the Z-axis direction. Then, by controlling the servo motor unit 150Z by switching the rotational direction of the servo motor unit 150Z in a short cycle, the stage 5100 can be excited in the Z-axis direction (up-and-down direction) with a desired amplitude and period.

從支撐機構5440之軸承支撐板5442的下面，經由2片連結板 5443而固定有朝水平方向(XY平面)擴大之馬達支撐板5446。在馬達支撐板5446之下面吊掛伺服馬達單元150Z而固定。在馬達支撐板5446中設有開口部446a，伺服馬達單元150Z之驅動軸152Z貫穿該開口部446a，而在馬達支撐板5446之上面側與滾珠螺桿5418連結。 From the underside of the bearing support plate 5442 of the support mechanism 5440, via two webs A motor support plate 5446 that is enlarged in the horizontal direction (XY plane) is fixed to 5443. The servo motor unit 150Z is suspended below the motor support plate 5446 and fixed. An opening 446a is provided in the motor support plate 5446, and the drive shaft 152Z of the servo motor unit 150Z penetrates the opening 446a, and is coupled to the ball screw 5418 on the upper surface side of the motor support plate 5446.

另外，本實施形態中，因為伺服馬達單元150Z之軸方向(上 下方向，Z軸方向)的尺寸比框架5422之高度大，所以伺服馬達單元150Z之大部分配置於比基板5402低之位置。因而，在裝置基座5002中設有用於收納伺服馬達單元150Z之空洞部5002a。此外，在基板5402中設有伺服馬達單元150Z通過用之開口5402a。 In addition, in the present embodiment, because of the axial direction of the servo motor unit 150Z (on Since the dimension in the downward direction and the Z-axis direction is larger than the height of the frame 5422, most of the servo motor unit 150Z is disposed at a position lower than the substrate 5402. Therefore, the device base 5002 is provided with a cavity portion 5002a for accommodating the servo motor unit 150Z. Further, an opening 5402a through which the servo motor unit 150Z passes is provided in the substrate 5402.

軸承部5416係貫穿軸承支撐板5442而設置。另外，由於軸承 部5416之構造與第一致動器5200中之軸承部5216(第三十四圖、第三十五圖)同樣，因此省略詳細之說明。 The bearing portion 5416 is provided to penetrate the bearing support plate 5442. In addition, due to the bearing The structure of the portion 5416 is the same as that of the bearing portion 5216 (the thirty-fourth and thirty-fifth views) in the first actuator 5200, and thus detailed description thereof will be omitted.

其次，說明連結部5430之構成。連結部5430具有活動框架 5432、一對X軸軌道5434、一對Y軸軌道5435、複數個中間載台5431、二對Z軸軌道5437、及二對Z軸轉子塊5433。 Next, the configuration of the connecting portion 5430 will be described. The joint 5430 has a movable frame 5432, a pair of X-axis rails 5434, a pair of Y-axis rails 5435, a plurality of intermediate stages 5431, two pairs of Z-axis rails 5437, and two pairs of Z-axis rotor blocks 5433.

活動框架5432具有固定於滾珠螺帽5419之框部5432a、固定 於框部5432a之上端的頂板5432b、及從頂板5432b之X軸方向兩緣向下方伸出而固定的側壁5432c。一對Y軸軌道5435係一起向Y軸方向伸出之軌道，並在活動框架5432之頂板5432b的上面並列於X軸方向而固定。此外，一對X軸軌道5434係一起向X軸方向伸出之軌道，且在平台5100之下面並列於Y軸方向而固定。中間載台5431係為將與X軸軌道5434結合之X軸轉子塊5431a設於上部，並將與Y軸軌道5435之各個結合的Y軸轉子塊5431b設於下部之方塊，且構成可對X軸軌道5434及Y軸軌道5435兩者滑動。另外，中間載台5431係在X軸軌道5434與Y軸軌道5435交叉之各位置各設一個。由於X軸軌道5434與Y軸軌道5435分別各設2個，因此X軸軌道5434與Y軸軌道5435在4處交叉。因此本實施形態中使用4個中間載台5431。 The movable frame 5432 has a frame portion 5432a fixed to the ball nut 5419, and is fixed. A top plate 5432b at an upper end of the frame portion 5432a and a side wall 5432c extending downward from both edges of the top plate 5432b in the X-axis direction are fixed. A pair of Y-axis rails 5435 are rails that project together in the Y-axis direction, and are fixed in the X-axis direction on the top surface of the top plate 5432b of the movable frame 5432. Further, a pair of X-axis rails 5434 are rails that project together in the X-axis direction, and are fixed in the Y-axis direction below the platform 5100. The intermediate stage 5431 is provided with an X-axis rotor block 5431a coupled to the X-axis rail 5434 at the upper portion, and a Y-axis rotor block 5431b coupled to each of the Y-axis rails 5435 is disposed at the lower square, and constitutes a pair X. Both the shaft rail 5434 and the Y-axis rail 5435 slide. Further, the intermediate stage 5431 is provided at each of the positions where the X-axis rail 5434 and the Y-axis rail 5435 intersect. Since the X-axis rail 5434 and the Y-axis rail 5435 are respectively provided in two, the X-axis rail 5434 and the Y-axis rail 5435 intersect at four places. Therefore, in the present embodiment, four intermediate stages 5431 are used.

如此，各個中間載台5431對平台5100可在X軸方向滑動，且對活動框架5432可在Y軸方向滑動。亦即，活動框架5432可對平台5100在X軸方向及Y軸方向滑動。因而，即使平台5100藉由其他致動器5200及/或5300而在X軸方向及/或Y軸方向勵磁，活動框架5432仍不致因此而變位。亦即，因平台5100在X軸方向及/或Y軸方向之變位而產生的彎曲應力不致施加於滾珠螺桿5418或軸承部5416、耦合器5460等。 In this manner, each of the intermediate stages 5431 can slide in the X-axis direction with respect to the stage 5100, and can slide in the Y-axis direction with respect to the movable frame 5432. That is, the movable frame 5432 can slide the platform 5100 in the X-axis direction and the Y-axis direction. Thus, even if the stage 5100 is excited in the X-axis direction and/or the Y-axis direction by the other actuators 5200 and/or 5300, the movable frame 5432 is not displaced thereby. That is, the bending stress generated by the displacement of the stage 5100 in the X-axis direction and/or the Y-axis direction is not applied to the ball screw 5418, the bearing portion 5416, the coupler 5460, or the like.

此外，本實施形態中，因為在活動框架5432上支撐重量比較 大之平台5100及工件，所以X軸軌道5434及Y軸軌道5435所取之間隔比第一致動器5200之Y軸軌道5234及Z軸軌道5235寬。因而，與第一致動器5200同樣地，設為僅藉由一個中間載台連結平台5100與活動框架5432之構成時，中間載台將大型化，導致施加於活動框架5432之載荷增大。因而，本實施形態中，係設為在每一X軸軌道5434與Y軸軌道5435交叉之各部分配置小型的中間載台5431之構成，以將施加於活動框架5432之載荷大小抑制在必要最低限度。 In addition, in this embodiment, the weight comparison is supported on the movable frame 5432. The large platform 5100 and the workpiece, so the X-axis rail 5434 and the Y-axis rail 5435 are spaced apart from each other by the Y-axis rail 5234 and the Z-axis rail 5235 of the first actuator 5200. Therefore, similarly to the first actuator 5200, when only one intermediate stage is connected to the movable frame 5320 and the movable frame 5432, the intermediate stage is increased in size, and the load applied to the movable frame 5432 is increased. Therefore, in the present embodiment, a configuration is adopted in which a small intermediate stage 5431 is disposed in each of the X-axis rails 5434 and the Y-axis rails 5435, so that the load applied to the movable frame 5432 is suppressed to the minimum necessary. limit.

二對Z軸軌道5437係向Z軸方向伸出之軌道，且在活動框架 5432之各側壁5432c並列於Y軸方向而各一對固定。Z軸轉子塊5433與該Z軸軌道5437之各個結合，並可沿著Z軸軌道5437而滑動。Z軸轉子塊5433經由轉子塊安裝構件5438而固定於框架5422之頂板5422b的上面。轉子塊安裝構件5438具有與活動框架5432之側壁5432c概略平行配置的側板5438a、及固定於該側板5438a之下端的底板5438b，整體成為L字形剖面形狀。此外，本實施形態中，特別是將重心高且重量大之工件固定於平台5100上時，X軸周圍及/或Y軸周圍之大力矩容易施加於活動框架5432上。因而轉子塊安裝構件5438係藉由肋條補強以承受該轉動力矩。具體而言，係在轉子塊安裝構件5438之Y軸方向兩端的側板5438a與底板5438b構成之角落設置一對第一肋條5438c，進一步設有橫跨該一對第一肋條5438c之間的第二肋條5438d。 Two pairs of Z-axis rails 5437 are rails that extend in the Z-axis direction and are in the movable frame Each of the side walls 5432c of the 5432 is juxtaposed in the Y-axis direction and fixed to each other. The Z-axis rotor block 5433 is combined with each of the Z-axis rails 5437 and is slidable along the Z-axis rail 5437. The Z-axis rotor block 5433 is fixed to the upper surface of the top plate 5422b of the frame 5422 via the rotor block mounting member 5438. The rotor block mounting member 5438 has a side plate 5438a disposed substantially in parallel with the side wall 5432c of the movable frame 5432, and a bottom plate 5438b fixed to the lower end of the side plate 5438a, and has an L-shaped cross-sectional shape as a whole. Further, in the present embodiment, in particular, when a workpiece having a high center of gravity and a large weight is fixed to the stage 5100, a large moment around the X-axis and/or around the Y-axis is easily applied to the movable frame 5432. Thus, the rotor block mounting member 5438 is reinforced by the ribs to withstand the rotational moment. Specifically, a pair of first ribs 5438c are provided at corners of the side plates 5438a and the bottom plates 5438b at both ends of the rotor block mounting member 5438 in the Y-axis direction, and a second is provided between the pair of first ribs 5438c. Rib 5438d.

如此，Z軸轉子塊5433固定於框架5422，且可對Z軸軌道5437 滑動。因此，活動框架5432可在上下方向滑動，並且管制活動框架5432在上下方向以外之移動。如此，因為活動框架5432之移動方向僅限制在上下 方向，所以驅動伺服馬達單元150Z而使滾珠螺桿5418轉動時，活動框架5432及與該活動框架5432結合之平台5100在上下方向進退。 As such, the Z-axis rotor block 5433 is fixed to the frame 5422 and can be aligned with the Z-axis track 5437. slide. Therefore, the movable frame 5432 can slide in the up and down direction and regulate the movement of the movable frame 5432 in the up and down direction. So, because the moving direction of the movable frame 5432 is only limited to the upper and lower In the direction, when the servo motor unit 150Z is driven to rotate the ball screw 5418, the movable frame 5432 and the platform 5100 coupled to the movable frame 5432 advance and retreat in the up and down direction.

此外，與第一致動器5200之位置檢測手段5250(第三十四圖、第三十五圖)同樣之位置檢測手段(無圖示)亦設於第三致動器5400。振動測試裝置5000之控制單元C5可依據該位置檢測手段之檢測結果，控制活動框架5432之高度在指定之範圍內(第三十八圖)。 Further, a position detecting means (not shown) similar to the position detecting means 5250 (thirty-fourth and thirty-fifth views) of the first actuator 5200 is also provided in the third actuator 5400. The control unit C5 of the vibration testing device 5000 can control the height of the movable frame 5432 within a specified range according to the detection result of the position detecting means (the thirty-eighth figure).

如以上之說明，本實施形態中，在驅動軸彼此正交的各致動器與平台5100之間設有二對軌道與可對該軌道滑動而構成的中間載台。藉此，平台5100對各致動器可在與其致動器之驅動方向垂直的面上之任意方向滑動。因而，即使因某個致動器造成平台5100變位，因該變位產生之載荷及力矩不致施加於其他致動器，且維持其他致動器與平台5100經由中間載台而結合的狀態。亦即，即使平台在任意位置變位，仍然維持各致動器可使平台變位之狀態。因而，本實施形態中可同時驅動3個致動器5200、5300、5400，而將平台5100及固定於其上之工件在3軸方向勵磁。 As described above, in the present embodiment, between the actuators orthogonal to the drive shafts and the stage 5100, two pairs of rails and an intermediate stage that can slide the rail are provided. Thereby, the platform 5100 can slide each actuator in any direction on a plane perpendicular to the driving direction of the actuator. Therefore, even if the platform 5100 is displaced due to an actuator, the load and torque generated by the displacement are not applied to the other actuators, and the state in which the other actuators and the platform 5100 are coupled via the intermediate stage is maintained. That is, even if the platform is displaced at any position, the state in which the actuators can displace the platform is maintained. Therefore, in the present embodiment, the three actuators 5200, 5300, and 5400 can be simultaneously driven, and the stage 5100 and the workpiece fixed thereto are excited in the three-axis direction.

本實施形態中，如前述，在致動器5200、5300、5400與平台5100之間設有具備組合軌道與轉子塊之引導機構的連結部。此外，同樣之引導機構設於致動器5200、5300、5400，該引導機構係用作引導各致動器之滾珠螺桿機構的螺帽。 In the present embodiment, as described above, a connecting portion having a guiding mechanism for combining the rail and the rotor block is provided between the actuators 5200, 5300, and 5400 and the stage 5100. Further, the same guiding mechanism is provided to the actuators 5200, 5300, 5400, which serve as nuts for guiding the ball screw mechanisms of the respective actuators.

此外，上述各種實施形態中，轉矩產生裝置中係使用超低慣性伺服馬達，不過本發明之構成不限定於此。使用轉子之慣性力矩小、可以高加速度或是高加加速度驅動之其他形式的電動機(例如變頻調速馬達)之構成亦包含於本發明。此時，與上述各種實施形態同樣地，可採用在電 動機中設置編碼器，依編碼器檢測之電動機輸出軸的轉動狀態(例如轉數及角度位置)進行反饋控制之構成。 Further, in the above-described various embodiments, an ultra-low inertia servo motor is used in the torque generating device, but the configuration of the present invention is not limited thereto. The construction of other types of motors (e.g., variable frequency speed control motors) using a small inertia moment of the rotor and capable of driving at high acceleration or high acceleration is also included in the present invention. In this case, similarly to the above various embodiments, it is possible to use electricity. The encoder is provided with an encoder, and the feedback control is performed according to the rotation state (for example, the number of revolutions and the angular position) of the motor output shaft detected by the encoder.

此外，上述實施形態主要係在汽車用動力傳達裝置之耐久測 試裝置中適用本發明之例，不過本發明不限定於此，在一般產業中可使用於各種用途。例如在兩輪車、農業機械、建設機械、鐵路車輛、船舶、飛機、發電系統、給排水系統或是構成此等之各種零件的機械特性及耐久性之評估時可使用本發明。 In addition, the above embodiment is mainly used for durability testing of a power transmission device for an automobile. The example of the present invention is applied to the test apparatus, but the present invention is not limited thereto, and can be used for various purposes in the general industry. The invention may be used, for example, in the evaluation of mechanical properties and durability of two-wheeled vehicles, agricultural machinery, construction machinery, railway vehicles, ships, aircraft, power generation systems, water supply and drainage systems, or the various components that make up such.

以上係說明本實施形態，不過本發明並非限定於上述構成 者，在本發明之技術性思想範圍內可作各種變形。例如，上述各種實施形態中，係使用兩階連結一個(具有1個輸出軸)伺服馬達150B與1個雙軸輸出伺服馬達150A的伺服馬達單元150(或轉矩賦予用伺服馬達單元132)，不過亦可使用三階以上連結一個伺服馬達150B與複數個雙軸輸出伺服馬達150A的伺服馬達單元之構成。 The present embodiment has been described above, but the present invention is not limited to the above configuration. Various modifications are possible within the scope of the technical idea of the invention. For example, in the above-described various embodiments, the servo motor unit 150 (or the torque applying servo motor unit 132) that connects one (one output shaft) servo motor 150B and one biaxial output servo motor 150A in two stages is used. However, a servo motor unit in which one servo motor 150B and a plurality of two-axis output servo motors 150A are connected in three or more stages may be used.
