本考案は、ファクシミリ、複写機などの紙送り用、または、プリンタの印字ヘ ッド等に使用されるモータの振動および騒音防止のために用いられる防振ゴムに 関する。 The present invention relates to an anti-vibration rubber used for feeding paper for a facsimile, a copying machine, etc., or for preventing vibration and noise of a motor used in a printing head of a printer.
【０００２】[0002]
近年、オフィス等のＯＡ化に伴って、ＯＡ機器の振動や騒音が注目されるよう になった。その一つの原因は、ＯＡ機器に内蔵されたモータが駆動したとき、前 記モータの振動が機器のフレームに伝達することによるものであった。そこで従 来より、モータと機器本体のフレームとの間に防振ゴムを介し、振動の伝達を防 止し騒音を抑制していた。図３にモータの取付けに使用される従来の防振ゴム１ を示す。防振ゴム１は、取り付け孔２，２…を有する２枚の基板３，３間に、ゴ ム体４（クロロプレンゴムまたはブチルゴム等）を加硫接着したもので、モータ の駆動軸が通せるように中央に中空孔５が設けられている（実願昭６２−１６６ ２８９）。この様な防振ゴム１は、例えば図４のプリンタのプラテン駆動機構に 使用される。プリンタのプラテン駆動機構のようなギア駆動装置は、ステッピン グモータ６の駆動軸７に設けられたピニオン８から、プラテン９のプラテン軸１ ０に設けられたギア１１に回転運動が伝達され、プラテン９を駆動するものであ る。この場合、ステッピングモータ６の振動がプラテン９に伝達するのを防止す るため、ステッピングモータ６とフレーム１２の間に防振ゴム１を挿入し、それ ぞれに対して取り付け孔２，２…を用いてボルト止めして固定している。 In recent years, as offices have become OA, vibration and noise of OA equipment have come to the forefront. One of the causes was that when the motor built into the office automation equipment was driven, the vibration of the motor was transmitted to the frame of the equipment. Therefore, conventionally, a vibration-proof rubber was interposed between the motor and the frame of the main body of the device to prevent the transmission of vibration and suppress noise. FIG. 3 shows a conventional anti-vibration rubber 1 used for mounting a motor. The anti-vibration rubber 1 is made by vulcanizing and adhering a rubber body 4 (chloroprene rubber, butyl rubber, etc.) between two substrates 3, 3 having mounting holes 2, 2, ..., Through which the drive shaft of the motor can pass. Thus, the hollow hole 5 is provided in the center (Japanese Utility Model Application No. 62-166289). Such an anti-vibration rubber 1 is used, for example, in the platen drive mechanism of the printer shown in FIG. In a gear driving device such as a platen driving mechanism of a printer, a rotary motion is transmitted from a pinion 8 provided on a driving shaft 7 of a stepping motor 6 to a gear 11 provided on a platen shaft 10 of a platen 9 so that the platen 9 Is to drive. In this case, in order to prevent the vibration of the stepping motor 6 from being transmitted to the platen 9, the anti-vibration rubber 1 is inserted between the stepping motor 6 and the frame 12, and the mounting holes 2, 2 ... It is fixed by bolting with.
【０００３】[0003]
しかしながら、従来の防振ゴム１を図４のように取り付けた場合、ピニオン８ および駆動軸７にはギア１１の回転と逆方向の外力Ｆが加わる。従って、防振ゴ ム１の外力Ｆ方向（紙面奥）側部に引張り力が、外力の反対方向（紙面手前）側 部に圧縮力が作用する。これらの力を受けることにより防振ゴム１は歪みを生じ 、モータ６の駆動軸７およびピニオン８の位置をずらすことがわかった。さらに 、この状態でモータ６を駆動すると、モータ６の振動が防振ゴム１の歪みを増大 させ、プラテン装置そのものの位置決め精度を著しく低下させていた。以上、ギ ア駆動装置の場合について説明したが、ベルト駆動装置では、図５のように、ベ ルト１３の張力Ｉの方向にモータ６の駆動軸７およびピニオン８が引き付けられ るので、防振ゴム１の右半分に圧縮力が作用して経時的に圧縮歪みが生じ、また 、左半分に引張り力が作用して引張り歪みおよびクリープが発生する。 However, when the conventional anti-vibration rubber 1 is attached as shown in FIG. 4, an external force F in the direction opposite to the rotation of the gear 11 is applied to the pinion 8 and the drive shaft 7. Therefore, a tensile force acts on the side of the anti-vibration rubber 1 in the direction of the external force F (back of the paper), and a compressive force acts on the side of the anti-vibration rubber 1 in the direction opposite to the external force (front of the paper). It has been found that the vibration isolating rubber 1 is distorted by receiving these forces, and the positions of the drive shaft 7 and the pinion 8 of the motor 6 are displaced. Further, when the motor 6 is driven in this state, the vibration of the motor 6 increases the distortion of the vibration isolating rubber 1 and remarkably lowers the positioning accuracy of the platen device itself. The case of the gear drive device has been described above. However, in the belt drive device, the drive shaft 7 and the pinion 8 of the motor 6 are attracted in the direction of the tension I of the belt 13 as shown in FIG. A compressive force acts on the right half of the rubber 1 to cause compressive strain over time, and a tensile force acts on the left half to cause tensile strain and creep.
【０００４】 これらの欠点を解消するために、防振ゴム１のゴム体４として、より硬度の大 きいゴムを用いたり、より体積の大きなゴムを用いるなどして、防振ゴム１のば ね定数を大きくし、歪みを抑制する工夫が施されていたが、反面、防振効果が低 下するという問題が生じた。In order to eliminate these drawbacks, the rubber body 4 of the anti-vibration rubber 1 is made of rubber having a higher hardness, a rubber having a larger volume, or the like. Although an attempt was made to increase the constant and suppress distortion, on the other hand, there was a problem that the anti-vibration effect was reduced.
【０００５】 そこで本考案は、防振効果を低下させることなく防振ゴムの歪みや変位を小さ くし、装置の位置決め精度を向上させることを目的とする。Therefore, the present invention aims to improve the positioning accuracy of the device by reducing the distortion and displacement of the antivibration rubber without reducing the antivibration effect.

本考案の一実施例を図１にしたがって説明する。 図１の（ａ）は、本考案の一実施例のモータ用防振ゴム２０の平面図、（ｂ） は線Ｂ−Ｂに添う断面図、（ｃ）は線Ｃ−Ｃに添う断面図である。 モータ用防振ゴム２０は、第１の基板２１と、第２の基板２２と、この２枚の 基板間に介挿され、加硫接着されたゴム体２３とから構成されている。 第１の基板２１と第２の基板２２にはそれぞれ２個づつの取り付け孔２４，２ ４，２５，２５が設けられており、第１の基板２１上の取り付け孔２４，２４は 、対向して張り出した突出部２６，２６の先端部分に設けられている。そして、 第２の基板２２上の取り付け孔２５，２５は、第１の基板２１の取り付け孔２４ ，２４と約９０°ずらした位置の突部上に配設される。また、第１の基板２１の 突出部２６，２６と相対するように、第２の基板２２にも突出部２７，２７が形 成され、ゴム体２３は基板２１，２２と略同じ輪郭を有する形状に金型成型され る。そして、この様なモータ用防振ゴム２０中央には、モータの駆動軸を通す、 ほぼ円筒形状の中空孔２８が設けられる。 An embodiment of the present invention will be described with reference to FIG. FIG. 1A is a plan view of a rubber vibration isolator 20 for a motor according to an embodiment of the present invention, FIG. 1B is a sectional view taken along line BB, and FIG. 1C is a sectional view taken along line CC. Is. The motor anti-vibration rubber 20 is composed of a first substrate 21, a second substrate 22, and a rubber body 23 that is interposed between the two substrates and is vulcanized and bonded. Each of the first board 21 and the second board 22 is provided with two mounting holes 24, 24, 25, 25, and the mounting holes 24, 24 on the first board 21 face each other. It is provided at the tip of the projecting portions 26, 26 that overhang. Then, the mounting holes 25, 25 on the second substrate 22 are arranged on the projections at positions displaced by about 90 ° from the mounting holes 24, 24 of the first substrate 21. Further, the second substrate 22 is also formed with protrusions 27, 27 so as to face the protrusions 26, 26 of the first substrate 21, and the rubber body 23 has substantially the same contour as the substrates 21, 22. Molded into shape. A hollow hole 28 having a substantially cylindrical shape, through which the drive shaft of the motor passes, is provided at the center of the rubber vibration isolator 20 for such a motor.
【００１４】 上述のモータ用防振ゴム２０のゴム体２３の圧縮方向、すなわち基板に対して 垂直な断面についてのみ考察する場合、第１の基板２１の取り付け孔２４，２４ を結ぶ線にそう断面（図ｃ）の面積は、他の断面の面積よりも大きく、また、取 り付け孔２５，２５を結ぶ線に添う断面（図ｂ）の面積は最も小さくなる。ゴム は、同材料、同硬度の場合、そのばね定数は体積が大きいほど大きいという性質 を持つ。モータ用防振ゴム２０に用いるゴム体２３の体積が一定ならば、ばね定 数は一定であり、防振効果も一様である。しかし、本考案のように、ゴム体２３ のある方向にゴムを偏らせることによれば、局部的にゴムの歪みを低減すること ができる。本考案のモータ用防振ゴム２０を介してモータをフレームに固定する には、図１の線Ｃ−Ｃの方向、すなわち、圧縮方向で切断した場合の断面積が最 大となる方向を、モータに付加される力方向に平行に固定するのが好ましい。When considering only the compression direction of the rubber body 23 of the vibration isolating rubber 20 for motors, that is, the cross section perpendicular to the substrate, the cross section is taken along the line connecting the mounting holes 24, 24 of the first substrate 21. The area of (FIG. C) is larger than the area of other cross sections, and the area of the cross section (FIG. B) along the line connecting the mounting holes 25, 25 is the smallest. Rubber has the property that the larger the volume, the larger the spring constant when the same material and the same hardness are used. If the volume of the rubber body 23 used for the vibration damping rubber 20 for the motor is constant, the spring constant is constant and the vibration damping effect is also uniform. However, by biasing the rubber in a certain direction of the rubber body 23 as in the present invention, it is possible to locally reduce the distortion of the rubber. In order to fix the motor to the frame via the motor anti-vibration rubber 20 of the present invention, the direction of line C-C in FIG. 1, that is, the direction in which the cross-sectional area becomes maximum when cutting in the compression direction, It is preferably fixed parallel to the direction of the force applied to the motor.
【００１５】 また、本考案のモータ用防振ゴムの固定構造では、モータとフレームとの間に 介挿する防振ゴムは、好ましくは、基板を有するほうが取り付け作業が簡単で、 適用可能なモータも多いと考えられるが、必ずしも基板を備えたものである必要 性はない。例えば、中空孔を有する楕円柱状のゴム体の断面積が最も大きい方向 が、モータに加わる最大力の方向と一致するように、モータの底板、あるいはフ レームに直接ゴム体を接着しても、同様の効果が得られる。このとき、モータの 駆動軸は中空孔を通す。Further, in the vibration isolating rubber fixing structure for a motor according to the present invention, it is preferable that the vibration isolating rubber interposed between the motor and the frame has a substrate so that the attaching operation is easy and the applicable motor is applicable. It is considered that there are many, but it does not necessarily have to have a substrate. For example, even if the rubber body is directly bonded to the motor bottom plate or frame so that the direction of the largest cross-sectional area of the elliptic rubber body with hollow holes matches the direction of the maximum force applied to the motor, The same effect can be obtained. At this time, the drive shaft of the motor passes through the hollow hole.
【００１６】 続いて、図２に本考案の他の実施例を示す。 これは、図１に示した一実施例に存在した突出部２６，２７を廃し、第１の基 板２１および第２の基板２２およびゴム体２３の形状を、取り付け孔２４，２４ ，２５，２５が設けられた突部２９，２９，３０，３０を除いて略円柱状とした 。そして、中空孔２８を楕円柱状とし、取り付け孔２４，２４を結ぶ線を１辺と した断面積を他の圧縮方向の断面積より大きくした。この防振ゴムを固定するに は、取り付け孔２４，２４の方向をモータに加わる力方向と一致するようにして 、基板２１，２２をモータおよびフレームに固定し、荷重を支持するようにする のが好適である。この実施例では、取り付け孔２４，２４の距離と、取り付け孔 ２５，２５の距離が等しいので、通常市販されるモータの底板の規格形状に適合 しやすいという利点がある。Next, FIG. 2 shows another embodiment of the present invention. This eliminates the protrusions 26 and 27 that were present in the embodiment shown in FIG. 1 and replaces the shapes of the first base plate 21, the second substrate 22 and the rubber body 23 with the mounting holes 24, 24, 25, and 25. Except for the protrusions 29, 29, 30, 30 on which 25 is provided, it has a substantially cylindrical shape. The hollow hole 28 has an elliptic cylindrical shape, and the cross-sectional area in which one side is a line connecting the mounting holes 24, 24 is larger than the cross-sectional area in the other compression directions. In order to fix the anti-vibration rubber, the mounting holes 24, 24 should be aligned with the direction of the force applied to the motor so that the substrates 21, 22 are fixed to the motor and the frame to support the load. Is preferred. In this embodiment, since the distance between the mounting holes 24 and 24 is equal to the distance between the mounting holes 25 and 25, there is an advantage that it is easy to conform to the standard shape of the bottom plate of a commercially available motor.
【００１７】 本考案において、防振ゴムの縦横に対応するゴム体の断面積比はモータの重量 や、駆動装置から受ける力により定められるものである。In the present invention, the cross-sectional area ratio of the rubber body corresponding to the length and width of the anti-vibration rubber is determined by the weight of the motor and the force received from the driving device.
【００１８】[0018]
本考案のモータ用防振ゴムを、同体積で防振効果は等しいと考えられるゴム体 を有する防振ゴムと比較すると、従来のものより許容荷重が大きいので、防振ゴ ムを小形化することができる。さらに、同体積のゴム体を用いた従来の防振ゴム より、モータに加わる外力の作用する方向の変位および圧縮歪み、引張り歪みは 減少し、モータの位置決め精度が向上するが、防振効果は低下しない。 Compared to the anti-vibration rubber for motors of the present invention, which has the same volume and anti-vibration effect and has the same anti-vibration effect, the allowable load is larger than the conventional one, so the anti-vibration rubber can be made smaller. be able to. Furthermore, compared with conventional anti-vibration rubber that uses a rubber body of the same volume, displacement, compression strain, and tensile strain in the direction in which the external force applied to the motor acts are reduced, and motor positioning accuracy is improved, but the anti-vibration effect is Does not fall.
