動力源としてモーターを使用するのが一般的である。OA equipment such as communication terminals, printers, computers, etc.
It is common to use a motor as the power source.
このようなＯＡ機器には、モーター側から従動軸側に、
振動が伝達されないことが要望されている。In such OA equipment, from the motor side to the driven shaft side,
It is desired that vibrations are not transmitted.

例えばキ一手段により固着して、モーターｌのトルクを
従動軸４に伝達するようになっている。A drive gear 3 is fixed to a drive shaft 2 formed by extending a motor shaft, and a driven gear 5 meshing with the drive gear 3 is fixed to the driven shaft 4 by, for example, a key means, so that the torque of the motor 1 is transferred to the driven shaft. 4.
上述のように、モーターｌは、ゴム板等の弾性板を介し
て機器筐体に取付けであるので、モーター１の起動時、
停止時等の衝撃、振動等が機器筐体に直接伝達される恐
れが少ない。As mentioned above, since the motor 1 is attached to the equipment casing via an elastic plate such as a rubber plate, when the motor 1 is started,
There is little risk that shocks, vibrations, etc., such as when stopped, will be directly transmitted to the equipment housing.

するという問題点がある。However, in the conventional torque transmission mechanism described above, the motor 1
Impacts, vibrations, etc. on the drive shaft 2. Vibration is transmitted to the driven shaft 4 via the driving gear 3 and the driven gear 5, or vibrations generated when the driven gear 5 and the driving gear 3 mesh are transmitted to the driven shaft 4, causing the casing to vibrate, or There is a problem in that the equipment generates noise.

して連結されるような構造にしたものである。In order to solve the above-mentioned conventional problems, the present invention provides a drive gear 3 fixed to a drive shaft 2 of a motor 1. In transmitting torque, a driven gear 5 pivotally supported on a driven shaft 4 is connected to a disc 8 fixed to the driven shaft 4 via an elastic member 10.

或いは駆動歯車３と従動歯車５の噛み合い時に発生する
振動エネルギーが、弾性部材１０により吸収される。According to the above means of the present invention, the driven gear 5 has the elastic member 10
Vibration energy generated in the motor 1 by being connected to the disc 8 fixed to the driven shaft 4 through the
Alternatively, the vibration energy generated when the drive gear 3 and the driven gear 5 mesh is absorbed by the elastic member 10.
よって、従動軸４が振動することがなくて、筐体が振動
したり、或いは機器より騒音が発生する恐れが少ない。Therefore, the driven shaft 4 does not vibrate, and there is less risk of the casing vibrating or generating noise from the equipment.
また、弾性体による従動歯車５の支持のままでは、駆動
時に、従動歯車５は駆動歯車３との軸距離を拡げる方向
に逃げ、伝達効率の劣化とか歯飛を生じる。この逃げを
無くすために、従動歯車５を従動軸４に枢支しておき、
円滑なトルク伝達をおこなわしめている。Further, if the driven gear 5 is still supported by the elastic body, the driven gear 5 escapes in a direction that increases the axial distance from the driving gear 3 during driving, resulting in deterioration of transmission efficiency and tooth skipping. In order to eliminate this escape, the driven gear 5 is pivotally supported on the driven shaft 4,
This ensures smooth torque transmission.

。A plurality of (four in the figure) elastic members 10 connecting the disk 8 and the driven gear 5 are made of rubber, for example, and have a cylindrical shape with a desired short length, and one end surface of each elastic member 10 has a
The fixing screw 11 is integrated with the elastic member 10 by fixing its small disk-shaped head (for example, by bonding with adhesive). Further, a fixing screw 12 is integrated with the elastic member 10 by fixing its small disk-shaped head (for example, by bonding with adhesive) to the other end surface of the elastic member 10.
