Abstract
The invention relates to a wobble drive, in which a shaft supports a wobble ring by means of a pivot bearing, a finger extending from said ring. To reduce vibrations caused by the movement of the finger, at least one balancing mass is configured on the shaft. Alternatively or in addition, at least one balancing mass can be provided on the wobble ring. This allows the vibrations that are caused naturally by the movement of the finger to be compensated.
Claims18
A wobble drive, comprising
- a shaft;
- a pivot bearing that is situated on the shaft and that is inclined in relation to an axis of rotation of the shaft;
- a wobble finger that extends away from the axis of rotation of the shaft and is held by the pivot bearing;
- wherein at least one balance mass is fashioned on the shaft.

A wobble drive, comprising
- a shaft;
- a pivot bearing that is situated on the shaft and that is inclined in relation to an axis of rotation of the shaft;
- a wobble ring held by the pivot bearing;
- a wobble finger that, at a linkage point, extends from the wobble ring radially to a center axis of the wobble ring;
- wherein, on the wobble ring, at least one balance mass is provided in an area that is situated neither at the linkage point nor opposite the linkage point, in relation to the center axis of the wobble ring.
