Abstract

PURPOSE:To remove backlash of a gear by installing a disc-shaped member eccentric from the rotational center of the gear between the gear and shaft, and transmitting the torque. CONSTITUTION:An elastic member 2 is recessed in a groove 6 concentrical with the rotational center 5 of a shaft member 4, a gear 1 and the shaft member 4 are supported afloat so that they are concentrical. Another elastic member 3 is recessed in a groove 7 formed at the periphery of a disc-shaped member 8, whose center is an eccentric shaft 9, and installed in an eccentric hole 15 provided at the side face of the gear 1, which is thus supported afloat on the shaft member 4 and transmits the torque. When torque is large, an O-ring is crushed, and the end face 14 of the disc-shaped member 8 in eccentricity is in direct contact with the inner surface of eccentric hole provided at the side face of the gear to thus perform transmission of the torque. This accomplishes an uncostly backlash removing device with less generation of noise.

However, the device was not only complicated and could not transmit sufficient rotational force, but also expensive.

０リング）を介して、軸部材４に結合する。<Examples and 17> Examples will be described below. In FIGS. 1 and 2, the gear 1 is coupled to the shaft member 4 via an elastic body 2.3 (in this case, for example, a rubber O-ring).

弾性体２は、軸部材４の回転中心５に対し同心の講６に
埋設し、歯車１と軸部材４とを、同心になるように、浮
動的に支持する。The elastic body 2 is embedded in a shaft 6 concentric with the rotation center 5 of the shaft member 4, and supports the gear 1 and the shaft member 4 in a floating manner so as to be concentric with each other.

支持すると同時に、回転力を伝達する。On the other hand, the elastic body 3 is embedded in a shaft 7 provided on the outer periphery of a disc-shaped member 8 centered on an eccentric shaft 9 that is spaced apart from the rotation center 5 of the shaft member 4 by an eccentric plate a. The gear 1 is incorporated into an eccentric hole 15 provided on the side surface of the shaft member 4 to floatingly support the gear 1 on the shaft member 4 and at the same time transmit rotational force.

ｆｉ車１と軸部材４との回転力の伝達は、たとえば軸部

回転力を伝達する。When the rotational force to be transmitted is small, the rotational force is transmitted through the O-ring 3, but when the rotational force is large, the O-ring is crushed and the end face 14 of the eccentric disc-shaped member 8 is
It directly contacts the inner surface of an eccentric hole provided on the side of the I-car and transmits rotational force.

スラストワッシャー１１はナツト１２によって軸４に固

実施例では偏心した円板状の部材を用いたが、これに限
定されないで、非円形の部材を用いても良い。Although an eccentric disk-shaped member is used in the embodiment, the present invention is not limited to this, and a non-circular member may also be used.
