Description of the Invention (1) [Industrial Use Field] The present invention relates to a drive device for a belt-type door switch, and particularly relates to, for example, an elevator door or a shop Drive devices for belt-type door switches such as automatic doors. [Previous Technology] Conventionally, a belt-type door switch driving device for opening and closing an elevator door has been known to reduce the output of a motor by a belt and a pulley, and use the deceleration output to drive a belt for a door switch ( Generally, it is called a toothed belt with an actuating belt.) The door is opened or closed, or the belt is used to drive the door by the decelerating output of a gear motor. And, in general, the elevator door switch drive device is provided with a detector that detects a person or an object trapped in the door. When this detector detects that a person or an object is trapped, it makes a The drive opens the elevator door. [Problems to be Solved by the Present Invention] In the conventional driving device, a combination of a belt and a pulley is used to transmit a motor output to a door opening and closing belt (actuating belt) by changing the input side and the output side. The pulley diameter is used to slow down the rotation of the motor. Therefore, when the gear reduction ratio is to be set high (because the diameter of the pulley on the input side is made smaller, and the pulley on the output side is made larger, the boundary is limited). Generally, there are only multiple stages. Therefore, it is difficult to reduce the weight, and there is a problem that the cost is likely to increase. In addition, although gear motors are used to reduce weight through multiple belts and pulleys @ combinations, they are loud and have an accident detector as described below. Therefore, the paper size is subject to the Chinese National Standard (CNS) A4. Specifications (210X297 mm)

比發生在各各部分之振動•騷音程度要大的振動·騷音」 之共振現象之發生，其結果，可以大幅地提高從馬達單元 含有確動皮帶以後之驅動裝置全體的靜肅性。 一方面，若關閉門1 0 1 、1 〇 2時在確動皮帶1 7 形成作用過大的負荷時，因施加於旋轉外殼1 1的負荷增 大，成爲使各滾筒3 1、3 2、3 3、4 1、_4 2、43 發生打滑。因此，即使當偵測器系統的故障等時，變成無 法檢知人或物被挾在門1 0 1 、1 0 2中並控制使停止馬 達軸6 0的旋轉，而發生在人或物被挾的狀態下使馬達單 元2繼續旋轉之狀況，也可以使其被挾的人或物不會受到 過大的力矩。也就是說，可以發揮在意外的情況的機械的 安全機能。 內藏遊星滾筒機構3 0、40之動力傳達單元3，因 爲是可在輕量的形態下設計較大的減速比的，所以藉由扁 平馬達的採用可以更容易謀求驅動全體的輕量化。 且，因爲將與牽轉具4 5 —體化之安裝凸緣12當作 馬達單元2的外殼的一部（馬達座6 1 )使用，所以可以 一邊謀求零件數量的減少，一邊增加馬達單元2及動力傳 達單元3的一體性。而且，因爲藉由將其之安裝凸緣1 2 固定在電梯的箱側的固定構件1 0 〇，設置驅動單元1， 所以成爲可謀求安裝形態的輕量化之外，也使合理的設計 (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -20- 546243 五、發明説明（18) 成爲可能。 (請先閱讀背面之注意事項再填寫本頁) 更具體的話，首先，安裝凸緣12因爲位置在遊星滾 筒機構3 0、4 0及馬達單元2的軸方向中間所以從安裝 凸緣1 2的單邊支撐距離L 1、L 2短縮。其結果，特別 是，成爲使在不會離安裝凸緣12很遠的位置承受有關旋 轉筐1 3之徑向方向及推力方向的荷重，可以將施加於安

3，直接形成供驅動確動皮帶1 7用的帶輪1 8 ( 1 0 6 )，所以不需要在驅動單元1之外另設帶輪，而可 以謀求驅動系的更輕量化之外，.並謀求構成的單純化及零 件點數的削減，期待成本的降低。 且，因爲在構成旋轉外殻1 1之軸承外殼1 4及牽轉 具4 5之間特意配置滾動軸承2 4，所以可以減輕施加於 遊星滾筒機構3 0、4 0的負擔，並可以提高旋轉外殼 1 1的旋轉支撐的安定性。也就是說，因爲在此滾動軸承 2 4承受作用在旋轉外殼1 1之推力荷重的全部及徑向荷 重的一部分，所以即使設置在承受大的推力荷重或徑向荷 重之形態下，也可以安定地旋轉遊星滾筒3 2、4 2。 且，在此驅動單元1中，因爲將遊星滾筒機構3 0、 4 0設成2段，所以減速比可以設成較大之外，因爲滾筒 間的摩擦接觸部的數量增加，所以可以謀求利用滾筒的打 滑之安全性的提昇及振動吸收性能的提昇。 且，因爲藉由使2段的遊星滾筒機構3 0、4 0朝軸 方向並排，而提高遊星滾筒機構3 0、4 0本身的軸承機 能，所以旋轉外殻1 1的旋轉安定性也提高。 然而，前述實施例的驅動單元1的情況，設有2段的 遊星滾筒機構3 0、4 0，但遊星滾筒機構也可只設成i 段，3段以上也可以。設成3段以上的多段的情況，只要 本紙張尺度適用中國國家標準（CNS ) A4規格（

Description of the invention (3), and the transmission that occurs on the belt side (door side). The passive blocking of the part of the star roller unit can prevent " The occurrence of the so-called resonance phenomenon that is caused by the vibrations that occur in each part with different solidity, and the result is the overall quietness. In addition, if the star roller unit has an increased load from its structure, each roller will slip and have a torque characteristic. Therefore, even if, for example, it is impossible to detect that a person or thing is trapped in a door and control it to reverse, the situation occurs when the person or thing is trapped, so that an object that is not too large can be applied. That is to say, in an unexpected situation. This function is particularly effective when the response of the door switch is set to be relatively large. However, the motor unit may be composed of a short motor. In this way, the motor unit is designed to be relatively small using the flat-horse-inch method, so it can block the vibration of the entire drive unit toward the motor unit side while maintaining the characteristics. Therefore, those who have a frequency can influence each other. The vibration and noise that are louder can greatly improve the unique characteristics of the driver. The measurement system is stopped and the motor torque is raised at the speed that can be generated. Progressive. Therefore, the unit of the motor is followed by the machine to perform a time-varying rotation such as a large obstacle on the output side of the motor, or the torque of a person or a safety machine that continues to rotate. The shaft is designed to be smaller in accordance with the axial direction of the star roller unit. The star roller unit may also be a basket-rotating type in which the basket member on the outer periphery of the unit is rotatable, and the basket member is integrated with the link roller. It is rotatably connected, and the basket member itself is formed to drive the aforementioned paper size to apply the Chinese National Standard (CNS) A4 specification (210X29 * 7mm). Order -6-546243 V. Description of the invention (4) Belt pulley. With this structure, since the basket member itself which is integrally rotated and linked with the link roller is formed as a pulley for driving the belt, it is not necessary to provide a separate pulley in addition to the driving device. Therefore, as compared with a case where a driving device is connected with a separate pulley, in addition to reducing the weight of the drive system, simplification of the structure and reduction in the number of components can be achieved, and cost reduction can be expected. In this case, the integration of the link roller and the basket member can also pass through the link roller to the basket member or the basket member. The fixed components up to the extension are poor. · According to this configuration, since the fixing member penetrating the link roller is supported by the basket members on both sides in the axial direction of the link roller, the integrated rigidity of the link roller and the basket member can be improved. Moreover, the link roller and the basket member can be easily integrated regardless of the number of stages of the star roller unit. In addition, the above-mentioned meteor roller unit has a plurality of stages, and the sun drum of the first stage of the meteor drum unit among the plurality of staged meteor drum units is subjected to the output rotation of the motor unit, and will support the first stage of the meteor drum unit including the first stage After the puller is sequentially connected to the sun roller of the satellite roller unit of the next stage, the puller of the final roller unit of the final stage is fixed, and the link roller of the final roller unit of the final stage is connected to the basket member at least. The basket member may be rotatably coupled together, and the basket member may be configured to be rotatable. In this configuration, because the star roller unit is set into multiple sections, the Chinese paper standard (CNS) A4 specification (210X297 mm) can be applied to this paper size. (Please note this page before filling in this page), τ Intellectual Property Bureau, Ministry of Economic Affairs Printed by the employee consumer cooperative 546243 5. Description of the invention (5) The overall outer diameter of the driving device is designed to be large, and a large reduction ratio can be easily designed on the side. In addition, since the number of frictional contact portions between the drums is increased, safety performance and vibration absorption performance are improved by slipping of the drums. In addition, because the function of the bearing of the star roller unit is improved, the rotation stability of the basket member is further improved. In addition, it is also possible to use a fixing device of the staring roller supporting the staring roller unit to the motor unit, and to form a driving device on a fixed member on the side of the anti-starring roller unit of the dragging device. The mounting flange is used as a part of the housing of the motor unit. • In this configuration, the mounting form can be reduced in weight compared to a case where a separate mounting space is provided on the motor unit side to fix it. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and this mounting flange is directly integrated with the drafting roller unit. Therefore, by fixing this mounting flange to a fixed member such as a box of an elevator, the distance between the bolt position of the mounting flange and the position where the load of the basket member is applied can be shortened. Therefore, compared with the case where a separate installation space is provided on the motor unit side for fixing, the reaction force moment applied to the installation space can be made smaller, and a design with higher installation stability can be made. Furthermore, in this configuration, since the mounting flange of the puller formed in the planetary roller unit is used as a part of the housing of the motor unit, the number of parts can be reduced. In addition, because the integration of the motor unit and the star roller unit can be increased, the rigidity of the entire device can be further improved. When the basket member and the link roller are integrally rotated, this paper G applies the Chinese National Standard (CNS) A4 (210X297 public director) Z '~ 546243 V. Description of the invention (6) Between the outer periphery of the drafting roller supporting the starring roller unit and the inner periphery of the basket member or the extension of the basket member It is also possible to configure bearings (please read the precautions on the back before filling this page). In other words, when the basket member and the link drum are rotated integrally, the reaction force or load input from the driven member side toward the basket member is directly applied to the link drum through the basket member. In general, when a simple star-walking structure of a traction roller is used, a load (particularly a thrust load) from the side of the connecting rod roller may cause smooth rotation, vibration, or noise increase of each roller. In the present invention, since a simple star-moving structure using a traction roller is used to achieve "silentness", if the basket member and the link roller are integrally rotated, in such a case, it is likely to be greatly affected by "from The load on the basket member side ". This kind of problem can be adopted by first extending the basket member from the connecting rod drum in the axial direction, and arranging the bearing (fixed to the external member) on the outer periphery of the drafting device and the extension of the basket member. Between the inner perimeter, it is solved with a very simple structure. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. If the bearing is configured in this way, the basket member for the output member is directly supported by the bearing fixed to the transfer device fixed to the external member. Therefore, even if, for example, a load is applied to the basket member from the driven member side, the load can be blocked by the bearing, the drafting device, and the external member, so the link roller can be smoothly and smoothly at any time without being affected by the load. Spin. However, the "extended material section of the basket member" does not necessarily have to be an integrated extended material, and the individual members can be combined to form the "extended material section". This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) ^ " " 546243 V. Description of invention (7) (Please read the precautions on the back before filling this page) However, this structure can also be used Applicable to power transmission device with multi-stage star roller unit. In this case, the power input from the input shaft is received by the sun roller of the star stage roller unit in the first stage of the star stage roller unit, and the draw rollers including the star stage roller unit before the first stage are sequentially connected to each other. The sun roller of the segmented roller unit is used as a fixed external member, and the link roller and the basket member can be integrally rotatably connected to each other to form a rotatable structure. The basket member can be extended from the link roller of the final stage roller unit in the axial direction, and the bearing is arranged on the outer periphery of the drafting device of the final stage and the extension of the basket member. Between weeks. However, with this bearing, the axial direction of the basket member with respect to the drafting device fixed to the external member is moved so as to be prevented by the bearing, and the thrust force applied from the basket member side by the presence of the bearing is applied It is also possible to convey the load on the side of the roller unit. Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Generally, the simple star-walking structure using traction rollers has the characteristic that the load in the radial direction is more likely to cause adverse effects than the load in the thrust direction. According to this configuration, since the bearing is disposed between the retractor and the basket member, the reaction force in the thrust direction can be slightly responded to. However, in this case, the bearing is actively used to prevent the shaft of the basket member of the retractor In the case of a directional movement structure, the link roller can be stably rotated even when a load in the thrust direction is applied from the side of the basket member to the link roller. However, in this case, the bearing itself, especially if it does not use thrust bearings, that is, does not use general ball bearings or roller bearings, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm)- 10- 546243 V. Description of the invention (9) A lightweight power transmission device with a motor. (Please read the precautions on the back before filling out this page.) Also, because there is only one central bearing for supporting the motor shaft, the cost is low. In addition, the planetary roller unit is arranged in parallel with the extended motor shaft i, and a part or all of the side surfaces in the axial direction of the retractor in contact with each stage are formed, and a plurality of connecting rod-shaped plates are arranged. The link-shaped plate in the front stage and the link-shaped plate in the rear stage may be used to limit the axial direction of the drafting device. In this configuration, for a power transmission device having a multi-stage star roller unit and a large reduction ratio, it is possible to prevent deviation of the drafting device, make the rotation smooth, and achieve quietness. In addition, by using the surface of the link-shaped plate, the axial direction of the drafting device and the star roller can be restricted by a small number of members. Furthermore, because the star roller unit is mounted on the extended motor shaft with a long span, the support for the output member of the motor shaft is stable.

A rolling bearing 2 4 is disposed between the outer periphery of the puller 4 5 and the inner periphery of the bearing housing 1 4 which is a part of the rotating housing (basket member) 1 1. In this way, the bearings 2 3, 2 4 of the revolving device 4 5 are used to enable the input shaft 20 to be rotatably supported on the revolving device 4 5, and the rotating basket 13 and the bearing housing 1 _ 4 are used. The rotating housing 11 is rotatably supported by the drafting device 45. Moreover, since the first and second planetary roller mechanisms 3 0 and 4 0 exert the function of bearings, they can be kept away from the bearings 2 3, 2 4 The position can also prevent the input shaft 20 and the rotary housing 11 from swinging.

Description of the invention (14) Special lubrication of the traction function of each roller of the mechanism 30 and 40 Here, the structure of the mounting flange 12 will be described, including the configuration of the arrangement of the aforementioned sealing member 55. The mounting flange 12 is used to fix the drive unit 1 of the present embodiment as described above. The elevator box-side fixing member 100 is used for the motor and is disposed on the motor unit 2 side of the power transmission unit 3. The mounting flange 12 is a motor seat 6 1 which also serves as a part of the housing of the motor unit 2. Structure and orthogonal to the axis direction of the drive unit 1. This mounting flange 12 is integrally formed with b at one end of the drafter 45 of the second star roller mechanism 40. Therefore, the mounting flange 12 is fixed to the box-side fixing member 1 0 of the elevator. , So that the second star roller mechanism 40 is kept in a fixed state, and it is made to take out the rotation from the rotating housing 1 1. In addition, the motor unit 2 also becomes a fixing member 100 fixed to the box side via the mounting flange 12. The side surface of the mounting flange 12 and the end surface of the bearing housing 14 are opposed to each other with some clearance, and are formed in the ring-shaped recess 1 2 a formed on the side surface of the mounting flange 12 side, and are formed in the bearing housing 1 4 The annular convex portion 1 4 a on the side is inserted in a non-contact manner. This is to form a ring-shaped convex portion 1 4 a on the side surface of the bearing housing 14 to secure a space for disposing the aforementioned sealing member 55 between the sealed bearing housing 14 and the retractor 45. That is, by forming the annular convex portion 14 a in the bearing housing 14, a space for disposing the sealing member 55 is ensured on the inner peripheral side. In order to avoid interference with the annular convex portion Γ 4 a, the The side surface on the flange 12 side forms an annular recess 1 2 a. — · II '4—, (Please read the notes on the back before filling out this page) Order printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs This paper is printed in accordance with Chinese National Standard (CNS) A4 (210X297 mm) 546243 Economy Printed by the Ministry of Intellectual Property Bureau's Consumer Cooperatives V. Invention Description (15) With this structure, while ensuring the thickness of the mounting flange 12 and the length of the shaft can be extended without the need to extend the axial direction, the sealing member 5 5 can be installed to make the mounting convex The edge 12 is arranged as close to the bearing housing 14 as possible to shorten the axial direction of the power transmission unit 3. Next, the configuration of the motor unit 2 will be described. Since this motor unit 2 is composed of the aforementioned flat commutated motor, the motor base 61 and the motor cover 63 constitute a motor housing. The motor base 6 1 also serves as the mounting flange 12 itself. The basic structure of this motor unit 2 is well-known in itself, and is mainly composed of: a motor shaft 60 integrated with the input shaft 20 of the power transmission unit 3; and a power transmission unit 3 and a support for the motor shaft 60. The opposite end is fitted with a bearing 6 at the center of the motor cover 6 3, a thin disc-shaped roller 6 5 that is combined with the outer periphery of the motor shaft 60 in the motor cover 63, and a roller The stator 6 5 with its side facing the stator 6 fixed to the inner side of the motor cover 6 3, the brush 6 (supplying a brush (not shown) 6 7) supplying current to the roller 6 5, and the brush 6 7 contacting the roller 6 5 is composed of a spring 6 8 for contact of the head. However, a roller is provided between the roller 65 and the bearing 23 on the inner periphery of the input shaft 20 on the power transmission unit 3 side. The spacer 6 for the position of 6 5 6. The drive unit 1 described above is fixed to the fixing member 1 0 0 by the mounting flange 1 2, for example, the box installed in the elevator as shown in FIG. 6. Figure 6 shows an example of the use of drive unit 1. This paper size applies to Chinese national standards (CNS> A4 size (210X297 mm) ~ '' (please first (Please read the notes on the back and fill in this page again) Reference numeral 104 is a connecting member of the door and the actuating belt. The actuating belt 17 is wound between two separated pulleys 105 and 106, and the driving unit 1 is arranged at the position of one of the pulleys 10 6 and The pulley 1 0 6 is a pulley 18 which is integrally formed in the rotating basket 1 3 of the rotating housing 11. In this mechanism, By driving the belt 17 with the drive unit 1, the doors 101 and 102 can be opened and closed simultaneously. Referring to FIG. 1, if the motor shaft 60 of the motor unit 2 rotates, its rotation is input from the input shaft 20 to the first star roller mechanism 3. 0 of the sun roller 3 1. Now suppose that when the rotating basket 1 3 is fixed, the rotation of the sun roller 31 1 is input, and the friction rotation (traction rotation) of the rollers will be based on the star roller 3 2 —drawing tool 3 5-the second star roller The order of the sun roller 41-the star roller 4 2-the retractor 45 of the mechanism 40 is conveyed. However, in fact, because the revolver 45 is fixed, by the rotation of the star rollers 3 2 and 4 2, the link rollers 3 3 and 4 3, that is, the rotating casing 11 including the rotating basket 13 is rotated, The drive actuates the belt 17 to open and close the doors 1 01 and 102. In this case, the power transmission means between the motor unit 2 and the moving belt 17 can be operated quietly because the power transmission unit 3 with the built-in star roller mechanism 30 and 40 is used. In other words, the planetary roller mechanism 30 and 40 are transmitted through the mutual rotation (frictional rotation or drag rotation) of the sun rollers 31 and 41 and the planetary rollers 3 2 and 4 2 and the link rollers 3 and 4 3. It is dynamic, so its own mute effect is very high, and the vibration of the motor unit 2 is transmitted to the moving belt side (please read the precautions on the back before filling this page) The paper size applies to the Chinese National Standard (CNS) A4 specification (2 丨 0X297 mm) 546243 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (17), and the transmission on the motor unit side of the vibration that occurs on the belt side, so as to move the same mechanism 3 Parts 0 and 40 are blocked. Therefore, it is possible to prevent the occurrence of the so-called resonance phenomenon that "vibrators with different natural frequencies interact with each other to generate vibrations and noises that are more severe than vibrations and noises that occur in each part." As a result, Significantly improves the quietness of the entire drive unit after the motor unit includes the belt. On the other hand, when the doors 1 0 1 and 1 2 are closed, when the belt 17 is actuated to generate an excessive load, the load applied to the rotating casing 11 increases, and each roller 3 1, 3 2, 3 3, 4 1, _4 2, 43 Slip occurred. Therefore, even when the detector system malfunctions or the like, it becomes impossible to detect that a person or an object has been trapped in the doors 1 0 1, 102 and controls the rotation of the motor shaft 60 to be stopped. In a state where the motor unit 2 continues to rotate in the state of being, the person or thing being trapped may not be subjected to excessive torque. In other words, the safety function of the machine can be exerted in an unexpected situation. The power transmission unit 3 of the built-in star roller mechanism 30 and 40 can be designed with a large reduction ratio in a lightweight form. Therefore, the use of a flat motor can make it easier to reduce the weight of the entire drive. In addition, since the mounting flange 12 integrated with the puller 4 5 is used as a part of the housing of the motor unit 2 (motor base 6 1), the number of parts can be reduced while the motor unit 2 can be increased. And power transmission unit 3. In addition, since the drive unit 1 is provided by fixing the mounting flange 1 2 to the fixing member 100 on the box side of the elevator, it is possible to reduce the weight of the mounting form and make a reasonable design (please Read the notes on the back before filling this page.) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -20- 546243 5. The invention description (18) becomes possible. (Please read the precautions on the back before filling in this page.) More specifically, first, the mounting flange 12 is located in the middle of the axis of the star roller mechanism 30, 40 and the motor unit 2. Therefore, the mounting flange 12 The unilateral support distances L 1, L 2 are shortened. As a result, in particular, the load on the radial direction and thrust direction of the rotating basket 13 can be received at a position not far from the mounting flange 12, and the bolt 6 2 can be applied to the mounting flange 12 The reaction torque is very small. Therefore, compared with a case where a separate installation space is provided on the motor unit side, the assembly stability when the drive unit 1 is installed in the elevator box is high. Next, because: a) The mounting flange 12 and the retractor 45 of the star roller mechanism 40 and the motor base 6 1 of the motor unit 2 are integrated and installed on the drive. The center of the unit 1, b) based on this mounting flange 12 to make the motor unit 2 and the star roller mechanism 30 in multiple stages 30, 40, the motor unit 2, the star roller mechanism (the final stage) 40, the same The sequence of the initial segment 30 is arranged next to each other on the same axis. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy. The shaft 2 0 is inserted into the star roller mechanism 3 0, which is arranged at the beginning of the farthest position from the motor unit 2. D) (the final stage) of the planetary roller mechanism 40, the puller 45 is fixed to the motor unit 2 (which is integrated with the mounting flange 1 2), so (roller or friction roller, etc.) The rotating member is assembled with the mounting flange 12 located at the center of the unit as the center. This paper size applies the Chinese national standard (CNS> A4 specification (210X297 mm> 546243). Explanation of the invention (19) The assembly rigidity of each rotating member can be maintained at a high level, and the rotation stability and the assembly stability of the box toward the elevator can be further improved. Moreover, because the link rollers 3, 4, 3 and the integral The rotating rotating basket 1 3 directly forms a pulley 18 (1 0 6) for driving the driving belt 17, so there is no need to provide a pulley outside the drive unit 1, and the drive system can be made lighter. Beyond quantification. We are also pursuing simplification of the structure and reduction of the number of parts, and we expect cost reduction. Furthermore, since the rolling bearing 2 4 is intentionally arranged between the bearing housing 14 and the retractor 45 constituting the rotating housing 11, the burden on the star roller mechanism 30 and 40 can be reduced, and the rotating housing can be increased. Stability of 1 1 swivel support. In other words, since the rolling bearing 24 receives the entire thrust load and a part of the radial load acting on the rotating housing 11 here, it can be stably set even when it is installed in a form that bears a large thrust load or a radial load. Rotate the star roller 3 2, 4 2. In addition, in this drive unit 1, the star roller mechanism 30 and 40 are set in two stages, so that the reduction ratio can be set to a large value, and because the number of frictional contact portions between the rollers is increased, it can be utilized. Improve the safety of drum slipping and vibration absorption performance. In addition, since the two-stage star roller mechanism 30 and 40 are aligned side by side in the axial direction, the bearing function of the star roller mechanism 30 and 40 itself is improved, so the rotation stability of the rotary housing 11 is also improved. However, in the case of the drive unit 1 of the foregoing embodiment, a two-stage star roller mechanism 30, 40 is provided, but the star roller mechanism may be provided only in the i stage, and three or more stages may be used. In the case of multiple segments with more than 3 segments, as long as this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling out this page) Printed 5. Description of the invention (20) The output of the motor unit is rotated by the sun roller of the first stage roller mechanism in the multi-stage star roller mechanism, and the pulling device and the second stage of the star roller mechanism including the first stage After the sun rollers of the star-shaped roller mechanism are connected in order, the drafting device of the star-shaped roller mechanism of the final stage is fixed, and the full-link rollers of the star-shaped roller mechanism of each stage can be integrally connected with the rotating basket. Even in this case, the bearing 24 may be arranged between the outer periphery of the final stage drag gear and the inner periphery of the bearing housing 14. In addition, the link rollers of each stage may be all connected, or only a part including the final stage may be connected. Fig. 3 shows an example in which the star roller mechanism is provided in one stage in the second embodiment. In this example, except that the planetary roller mechanism is changed from 2 to 丨, because it is basically the same structure as the previous embodiment, the same or similar components in Figure 3 are attached to the previous implementation The last two digits of the example have the same symbols, and duplicate descriptions are omitted. Next, a third embodiment of the present invention will be described using FIG. 4. In this third embodiment, the bearing 2 4 of the previous embodiment is abolished because the bearing 24 is abolished, especially for the load in the thrust direction or the radial direction from the rotating housing 2 1 1 side. Will back a few times than the previous embodiment, but the bearing is omitted. In part 2 and 4, the overall structure can be simplified and the axial length can be shortened. In particular, the shortening in this axial direction can not only reduce the weight of the overall shape of the power transmission unit 200, but also shorten the inch method from the mounting flange 2 12 to the load position, so that the overall assembly rigidity is reduced. (Please read the precautions on the back before filling in this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -23- 546243 V. Description of the invention (21) High, even if the thrust load is applied equally Or radial load can also make it difficult to affect the state of the link roller. Therefore, when it is applied to a place where the load in the thrust direction is not applied, sufficient performance can be maintained by this, and the weight and cost can be further reduced. However, the symbols 255, 255A, and 255B in the figure show the sealing members, respectively. The position of this seal member was arranged in parallel in the vicinity of the bearing 24 in the plural in the previous embodiment. However, because there is no part of the bearing and there is extra space, the arrangement of the sealing members 2 5 5, '2 5 5 A, and 2 5 5 B is simpler, the overall assembly is simpler, and one by one The sealing function of the sealing member can be brought into a better state. With regard to other structures, since there is basically no change from the previous first embodiment, only the same or similar parts with the same two-digit numbers are attached to the same or similar parts in the figure, and repeated description is omitted. However, omitting the structure of the bearing 24 is of course applicable to the second embodiment (single-stage type) of the previous embodiment. Next, a fourth embodiment of the present invention will be described with reference to Fig. 5. As shown in Fig. 5, the power transmission device 3 01 with a motor is also composed of a motor unit 3 0 2 and a flat commutator motor that aligns the compression shaft direction, and a two-stage star-shaped roller unit. power.

In this fourth embodiment, the bearing 3 2 4 is intentionally arranged between the rotating housing 3 1 1 and the retractor 3 4 5, so the application can be reduced. The load of the star roller units 330 and 340 can improve the stability of the rotary support of the rotary housing 3 1 1. In other words, since the bearing 3 2 4 receives a part of the thrust load and the radial load acting on the side opposite to the input shaft 3 2 0 of the rotating housing 3 1 1, even with a large thrust load or radial load, The setting can also make the star roller 3 3 2, 3, 4 2 rotate stably when the load is applied. However, when the thrust load on the motor unit 3 0 2 side is applied to the rotating housing 3 1 1, this thrust load is because Via the end cover 3 Γ 4, the side plate 3 3 9, the sun roller 3 3 1, the sun roller 3 4 1, and the side plate 3 4 9 are supported by the puller 3 4 5 without acting on the star roller 3 3 2, 3 4 2 so that the star roller 3 3 2, 3 4 2 can be stably rotated. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and since the pullers 335, star rollers 332, 342 are guided to the side plates 3 3 7, 3 3 8, 3 4 7, 3 4 8 and can be rotated, Deviations caused by processing errors can achieve smoothness and quietness of the drafting device of the star roller unit and the rotation of each drum. In addition, by using the front and back surfaces of the side plates, the axial movement of the drafting device and the star roller can be restricted by a small number of members. In addition, the retractors 335, 345 and the star roller 332, the paper size is applicable to the Chinese National Standard (CNS) A4 specifications (210X297 mm) -31-546243 V.

However, in the case of the motor-driven power transmission device 3 0 1 of the fourth embodiment, although the two-stage star roller unit 3 3 0 and 3 4 0 are provided, it is a matter of course that the star roller unit may have only one stage. There can also be more than 3 segments. Furthermore, in the foregoing embodiment, although the flat commutated motor is used as the motor unit, it is not limited to this. Furthermore, even if the drive unit 1 is not integrated with the motor unit and the power transmission unit, they can be separated and then connected to each other. Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and for the above-mentioned embodiments, although the bearing housing of "the extension of the basket member" and the rotating basket that is the body of the basket member are formed separately, they are mutually Connection, but of course these can also be a unified structure from the beginning. . And, for the above-mentioned embodiment, the so-called pure star roller unit is used as the star roller unit. This structure has many advantages in terms of weight reduction or integration of the motor unit. However, the star roller unit of the present invention does not necessarily require a simple star roller unit, and the specific type is not limited. For example: If the paper size of the special edition is suitable for financial affairs (CNS) A4 · (21GX297 mm) ~ — 546243 V.
