Description

この発明は、弾性材や摩擦材として用いられるゴムその他の粘弾性体の特性を環境温度を変化させて測定する装置に関するものである。   The present invention relates to an apparatus for measuring the characteristics of rubber and other viscoelastic bodies used as elastic materials and friction materials by changing the environmental temperature.

高温環境下でゴムの劣化が激しいことがよく知られているように、粘弾性体の特性は、環境温度によって変化する。一方、粘弾性体は、摩擦材やクッション材として機械装置の部品に広く用いられており、用途によっては環境温度によるこれらの部品の特性の変化が機械装置の性能に影響を及ぼすことがある。   As it is well known that rubber is severely deteriorated in a high temperature environment, the characteristics of the viscoelastic body change depending on the environmental temperature. On the other hand, viscoelastic bodies are widely used as parts of mechanical devices as friction materials and cushion materials, and depending on the application, changes in the characteristics of these components due to environmental temperature may affect the performance of the mechanical devices.

摩擦材やクッション材として用いることができる粘弾性体には、非常に多くの種類がある。屋外で使用する機械装置では、冬期と夏期で機械装置の性能が変化するのを防止し、あるいは環境温度の変化による性能の変化を適切に調整できることが必要である。そのためには、部品として使用する粘弾性体の特性がどのように変化するかを試験して、適切な材料を選択する必要がある。   There are numerous types of viscoelastic bodies that can be used as friction materials and cushion materials. In a mechanical device used outdoors, it is necessary to prevent a change in the performance of the mechanical device between winter and summer, or to appropriately adjust a change in performance due to a change in environmental temperature. For that purpose, it is necessary to test how the characteristics of the viscoelastic body used as a part change and to select an appropriate material.

環境温度の変化によって、粘弾性体の特性がどのように変化するかを示す資料は、各粘弾性体のメーカによって提供されているのが普通であるが、特殊な用途に使用する場合など、メーカから提供されている資料だけでは不十分な場合も多い。このような場合、機械装置のメーカは、製造しようとする機械装置に部品として使用する粘弾性体の特性を調べて、適切な材料を選択する必要が生ずる。このような場合、従来は適当と思われる材料をいくつか選んで、大学や試験場に粘弾性の測定を依頼している。   Documents that show how the properties of viscoelastic bodies change due to changes in environmental temperature are usually provided by the manufacturer of each viscoelastic body, but when used for special purposes, etc. In many cases, the materials provided by the manufacturer are not sufficient. In such a case, it is necessary for a manufacturer of a mechanical device to select an appropriate material by examining characteristics of a viscoelastic body used as a part in the mechanical device to be manufactured. In such a case, some materials that have been considered suitable are selected and viscoelasticity measurements are requested from universities and test sites.

大学や試験場は、高性能の制御器を備えているため、粘弾性体の試験においても高精度の測定を行うことができる。しかし、それほどの高精度の測定結果を必要とせず、より簡易に短時間で測定を行いたい場合も多い。常温で簡易に粘弾性を測定できる装置はあるが、環境温度によって特性がどのように変化するかを調べるためには、制御器が設置されている部屋の温度を変えて試験をしなければならず、通常の空調機では冬期と夏期の屋外の温度に相当するほど広い温度範囲で室内の温度を変えることができない。   Universities and test laboratories are equipped with high-performance controllers, so they can perform highly accurate measurements even in viscoelastic testing. However, there are many cases where it is not necessary to have a measurement result with such a high degree of accuracy, and it is easier to perform measurement in a shorter time. There are devices that can easily measure viscoelasticity at room temperature, but in order to investigate how the characteristics change depending on the environmental temperature, the temperature of the room where the controller is installed must be changed. However, a normal air conditioner cannot change the indoor temperature over a wide temperature range corresponding to the outdoor temperature in winter and summer.

そこでこの発明は、広い温度範囲に環境温度を変えて粘弾性体の特性を簡易に計測できる装置を提供することを課題としている。   Therefore, an object of the present invention is to provide an apparatus that can easily measure the characteristics of a viscoelastic body by changing the environmental temperature in a wide temperature range.

The vibration motor 6 to be performed is controlled by a controller 8 installed outside the storage box 1 and the rotation angle and torque of the motors 3 and 6 are detected by the controller to detect the tension machine 2 and the vibration generator 5. The properties of the viscoelastic body attached to the were measured.

Connect to the controller 8 installed outside the box. And after making the internal temperature of the storage box 1 into test temperature, the tension | pulling motor 3 is driven and the rotation angle and torque are measured.

By using the characteristic tester of the present invention, it is possible to quickly and easily measure the characteristics of a normally relatively small viscoelastic body used as a component of various mechanical devices at a necessary environmental temperature when necessary. Since it becomes possible, there is an effect that it is possible to develop a mechanical device that can exhibit stable performance even in a changing environmental temperature in a shorter time.

It is a box. The storage box 1 includes a door 11 of a single opening type on the front surface, and has a through-hole 12 for inserting a cable 85 that electrically connects the tension machine 2 and the vibrator 5 and the controller 8 stored on the side surface. I have.

引張機2及び引張試料4は、図2〜4に示されている。引張試料4は、図2に示すように、中央が幅狭となるように加工して、両端に取付孔42、42を設けたゴム板41の取付孔42を設けた部分の両面にステンレス製の座金43を接着した構造である。   The tensioner 2 and the tension sample 4 are shown in FIGS. As shown in FIG. 2, the tensile sample 4 is made of stainless steel on both sides of the portion where the mounting holes 42 of the rubber plate 41 provided with mounting holes 42, 42 at both ends are processed so that the center is narrow. The washer 43 is bonded.

引張試料4の引張試験を行う引張機2は、固定台21と門形のフレーム22との間に同期ベルト32(32a、32b)を介して1台の引張モータ3で同期駆動される2本のボールねじ23(23a、23b)を配し、固定台21とボールねじ23に螺合する移動台27との間に引張試料4を架け渡して引張モータ3を駆動することにより、移動台27を上昇させて引張試料4に引張力を与える構造である。引張試料4に与える引張力は、引張モータ3のトルクを検出することで測定でき、引張試料4の伸びは引張モータ3の回転数をカウントすることで測定できる。   Two tension machines 2 for performing a tensile test of the tensile sample 4 are synchronously driven by one tension motor 3 via a synchronous belt 32 (32a, 32b) between a fixed base 21 and a gate-shaped frame 22. The ball screw 23 (23a, 23b) is arranged, the tensile sample 4 is bridged between the fixed table 21 and the moving table 27 screwed to the ball screw 23, and the tension motor 3 is driven, thereby moving the moving table 27. This is a structure in which a tensile force is applied to the tensile sample 4 by raising. The tensile force applied to the tensile sample 4 can be measured by detecting the torque of the tensile motor 3, and the elongation of the tensile sample 4 can be measured by counting the number of rotations of the tensile motor 3.

引張機2をより詳細に説明すると、収納箱1の床面に定置される固定台21に門形のフレーム22が立設されている。鉛直方向の2本のボールねじ23(23a、23b)が、固定台21とフレーム22の上部に軸受24(24a、24b)、25(25a、25b)を介して自由回転可能に軸支されている。それぞれのボールねじ23の下方の軸受24から更に下方に突出した部分にプーリ26(26a、26b)が固定されている。プーリ26aと26bとは、高さ方向にずれた位置に設けられている。   The tension machine 2 will be described in more detail. A gate-shaped frame 22 is erected on a fixed base 21 placed on the floor surface of the storage box 1. Two ball screws 23 (23a, 23b) in the vertical direction are pivotally supported on the fixed base 21 and the upper portion of the frame 22 through bearings 24 (24a, 24b), 25 (25a, 25b) so as to be freely rotatable. Yes. Pulleys 26 (26 a, 26 b) are fixed to portions that protrude further downward from the bearings 24 below the respective ball screws 23. The pulleys 26a and 26b are provided at positions shifted in the height direction.

固定台21には、平面視で2本のボールねじ23a、23bの軸心から等距離の位置に出力軸の軸心を位置させて、引張モータ3が装着されている。引張モータ3の出力軸31には、幅広のプーリ36が固定され、ボールねじ23a、23bのプーリ26a、26bと同期ベルト32a、32bで回転連結されている。移動台27は、両端に装着したボールナット28(28a、28b)で2本のボールねじ23a、23bに螺合している。   A tension motor 3 is mounted on the fixed base 21 with the axis of the output shaft positioned at an equal distance from the axes of the two ball screws 23a and 23b in plan view. A wide pulley 36 is fixed to the output shaft 31 of the tension motor 3 and is rotationally connected to the pulleys 26a and 26b of the ball screws 23a and 23b by synchronous belts 32a and 32b. The movable table 27 is screwed to the two ball screws 23a and 23b by ball nuts 28 (28a and 28b) attached to both ends.

固定台21と移動台27の2本のボールねじ23a、23bのちょうど中間の位置に、引張試料4の端部を挿入するスリットと当該スリットを直角方向に貫通するピン孔とを備えた取付板44、45が設けられている。引張試料4は、その両端を取付板44、45のスリットに挿入し、それぞれのピン孔に挿通したピン46、47を引張試料の取付孔42、42に挿通することによって、両端を固定台21と移動台27とに係止される。   Mounting plate provided with a slit for inserting the end of the tensile specimen 4 and a pin hole penetrating the slit in a right angle direction at a position just between the two ball screws 23a and 23b of the fixed base 21 and the movable base 27 44 and 45 are provided. Both ends of the tensile sample 4 are inserted into the slits of the mounting plates 44 and 45, and the pins 46 and 47 inserted through the respective pin holes are inserted into the mounting holes 42 and 42 of the tensile sample, whereby both ends are fixed to the fixing base 21. And the movable table 27.

フレーム22には、移動台の下端位置と上限位置とを検出するリミットスイッチ48、49が設けられている。下端のリミットスイッチ48で移動台27が停止したときに、固定台の取付板44と移動台の取付板45との間隔が引張試料4の取付孔42、42の間隔と一致するように下端のリミットスイッチ48の位置を設定する。この下端の停止位置からの引張モータ3の回転数は、モータに取り付けたエンコーダで検出され、そのときのモータトルクは、モータを流れる電流値で検出される。   The frame 22 is provided with limit switches 48 and 49 for detecting the lower end position and the upper limit position of the moving base. When the moving table 27 is stopped by the lower limit switch 48, the lower end of the moving base 27 is aligned with the distance between the mounting holes 42, 42 of the tensile specimen 4 so that the distance between the mounting plate 44 of the fixed base and the mounting plate 45 of the moving base matches. The position of the limit switch 48 is set. The number of rotations of the tension motor 3 from the lower end stop position is detected by an encoder attached to the motor, and the motor torque at that time is detected by a current value flowing through the motor.

粘性を測定するための加振機5及び加振試料7は、図5、6に示されている。加振試料7は、円筒形のゴム71の両端にキャップ状のアダプタ72(72a、72b)を接着した構造で、アダプタ72の中心には、ねじ孔73(73a、73b)が設けられている。加振機に取り付けたときに下方となる下アダプタ72bのねじ孔73bには、予めスタッド74とその回り止めのロックナット75が装着されている。   A vibrator 5 and a vibrating sample 7 for measuring the viscosity are shown in FIGS. The vibration sample 7 has a structure in which a cap-shaped adapter 72 (72a, 72b) is bonded to both ends of a cylindrical rubber 71, and a screw hole 73 (73a, 73b) is provided at the center of the adapter 72. . A stud 74 and a lock nut 75 that prevents the rotation of the stud 74 are attached in advance to the screw hole 73b of the lower adapter 72b, which is downward when attached to the shaker.

加振機5は、基台51に固定したガイド筒52に上下方向移動自在に案内されたピストン54と加振モータ6で回転するクランク軸61とを連結ロッド62で連結した構造で、加振モータ6の回転によってピストン54を上下振動させる構造である。加振試料7は、ガイド筒52の上部とピストン54の上端との間に装架され、加振モータ6の回転数に対応する周波数でピストン54を振動して、加振試料7を繰り返し圧縮する。   The vibration exciter 5 has a structure in which a piston 54 guided by a guide cylinder 52 fixed to a base 51 so as to be movable in the vertical direction and a crank shaft 61 rotated by a vibration motor 6 are connected by a connecting rod 62. In this structure, the piston 54 is vibrated up and down by the rotation of the motor 6. The vibration sample 7 is mounted between the upper portion of the guide cylinder 52 and the upper end of the piston 54, and the piston 54 is vibrated at a frequency corresponding to the rotational speed of the vibration motor 6 to repeatedly compress the vibration sample 7. To do.

加振機5をより詳細に説明すると、収納箱1の床面に定置される基台51に出力軸を水平にして加振モータ6が装着されている。基台51には、その上面に円筒形のガイド筒52が固定されており、ガイド筒52にピストン54が上下方向に移動自在に案内されている。   Explaining the shaker 5 in more detail, the excitation motor 6 is mounted on the base 51 placed on the floor surface of the storage box 1 with the output shaft horizontal. A cylindrical guide cylinder 52 is fixed to the upper surface of the base 51, and a piston 54 is guided to the guide cylinder 52 so as to be movable in the vertical direction.

ピストン54の下端は二股形状になっており、加振モータ6の出力軸の先端は、軸心を0.5mm偏芯させた偏芯軸61となっている。そして、ピストン54の二股部分を貫通するように挿通したピストンピン63とクランク軸61とが、軸受64、65を介して、連結ロッド62で連結されている。ピストン54の上端には、加振試料7のスタッド74をねじ込むための座ぐり付きのねじ孔76が設けられており、スタッドのロックナット75は、座ぐり部分77に収容されるようになっている。   The lower end of the piston 54 has a bifurcated shape, and the distal end of the output shaft of the vibration motor 6 is an eccentric shaft 61 whose shaft center is eccentric by 0.5 mm. The piston pin 63 inserted so as to penetrate the bifurcated portion of the piston 54 and the crankshaft 61 are connected by a connecting rod 62 via bearings 64 and 65. A screw hole 76 with a counterbore for screwing the stud 74 of the vibration sample 7 is provided at the upper end of the piston 54, and the lock nut 75 of the stud is accommodated in the counterbore portion 77. Yes.

ガイド筒52の上端には、門形の上フレーム55が固定されている。上フレーム55を門形としているのは、その開口を通して引張試料4の装脱を行うことができるようにするためである。上フレーム55には、外周上部にねじを設けた押さえ筒56が挿通されている。上フレーム55の上端には、押さえ筒56のねじと螺合するナット部材57が載置され、ナット部材の上板58に挿通した長ボルト59が加振試料7の上アダプタ72aのねじ孔73aに螺入されるようになっている。   A gate-shaped upper frame 55 is fixed to the upper end of the guide cylinder 52. The reason why the upper frame 55 has a gate shape is to allow the tensile sample 4 to be loaded and unloaded through the opening. The upper frame 55 is inserted with a pressing cylinder 56 having a screw provided on the outer periphery. At the upper end of the upper frame 55, a nut member 57 screwed with a screw of the holding cylinder 56 is placed, and a long bolt 59 inserted through the upper plate 58 of the nut member is a screw hole 73a of the upper adapter 72a of the vibration sample 7. To be screwed in.

加振試料7は、長ボルト59とを抜き取ってナット部材57と押さえ筒56を持ち上げた状態で、上フレーム55の開口(図6の左右方向に開いている。)を通して挿入し、下アダプタ72bに取り付けたスタッド74をピストン54のねじ孔76に螺入して、下アダプタ72bをピストン54の上部に固定する。次に、ナット部材57を回して押さえ筒56を螺進退させて、押さえ筒56の下端で加振試料の上アダプタ72aを押し下げて、加振試料7が自然長から2mm圧縮された状態で固定されるように調整する。そして、上板58に長ボルト59を挿通して加振試料7の上アダプタ72aのねじ孔73aにねじ込んで締め付ける。この締め付けによって長ボルト59には引張力が作用し、押さえ筒56には圧縮力が作用して、加振試料7の上アダプタ72aが所定の高さで固定される。   The vibration sample 7 is inserted through the opening of the upper frame 55 (opened in the left-right direction in FIG. 6) with the long bolt 59 removed and the nut member 57 and the holding cylinder 56 lifted, and the lower adapter 72b. The stud 74 attached to is screwed into the screw hole 76 of the piston 54, and the lower adapter 72b is fixed to the upper part of the piston 54. Next, the nut member 57 is turned and the holding cylinder 56 is screwed back and forth, and the upper adapter 72a of the vibrating sample is pushed down at the lower end of the holding cylinder 56, and the vibrating sample 7 is fixed in a compressed state of 2 mm from the natural length. Adjust to be. Then, the long bolt 59 is inserted into the upper plate 58 and screwed into the screw hole 73a of the upper adapter 72a of the vibration sample 7 and tightened. By this tightening, a tensile force is applied to the long bolt 59 and a compressive force is applied to the holding cylinder 56, and the upper adapter 72a of the vibrating sample 7 is fixed at a predetermined height.

この状態で加振モータ6を回転させることにより、ピストン54が1mmのストロークで往復動し、加振試料7を繰り返し圧縮する。ピストン54の周期は、制御器8のインバータ81で加振モータ6の回転速度を制御することによって変更できる。   By rotating the vibration motor 6 in this state, the piston 54 reciprocates with a stroke of 1 mm, and the vibration sample 7 is repeatedly compressed. The cycle of the piston 54 can be changed by controlling the rotational speed of the vibration motor 6 with the inverter 81 of the controller 8.
