Wear-compensation device for a gear

摘要

The wear-compensation device for a gear comprises a fixed support (16) capable of being fixed axially on an external element (18) in order to keep the device on the said external element, a bearing (20) designed to be mounted on a shaft (14b) comprising one of the wheels of the gear, an eccentric (22) mounted on the bearing and designed to be in contact with the external element, the said eccentric being able to move angularly relative to the fixed support. The device also comprises a torsion spring (24) mounted axially between the fixed support and the eccentric and capable of exerting a circumferential preload force on the said eccentric, the said spring (24) comprising a first end mounted inside a recess (40) of the eccentric and a second end interacting with the fixed support (16).
