Abstract
In the case of a gear stage (1) of an actuating drive, in particular for a vehicle seat, having a bearing (12) which defines an axis (A12) and having an oscillatory body (11) which is mounted in a rotatable manner by the bearing (12), defines a further axis (A11) and, upon rotation of a driving mechanism (21), executes a rolling movement on the bearing (12), the axis (A11) of the oscillatory body (11) is inclined obliquely at an angle (α) relative to the axis (A12) of the bearing (12).
Claims22
A gear stage of an actuating drive that includes a driving mechanism, the gear stage comprising:
- fixed housing including a bearing defining an axis;
- and
- an oscillatory body defining an axis that is oblique to the axis of the bearing, the oscillatory body engaging the bearing at two contact points configured so that
- the oscillator body is for rolling on the bearing at the two contact points in response to rotation of the driving mechanism, and
- the oscillatory body rotates around both the axis of the bearing and the axis of the oscillatory body during the rolling of the oscillatory body on the bearing at the two contact points,
- wherein the bearing is configured so that the bearing is stationary with respect to the fixed housing during the rolling of the oscillatory body on the bearing at the two contact points.
A gear stage of an actuating drive that includes a driving mechanism, the gear stage comprising:
- a bearing defining an axis;
- and
- an oscillatory body defining an axis that is oblique to the axis of the bearing, the osculatory body engaging the bearing at two contact points configured so that
- the oscillatory body is for rolling on the bearing at the two contact points in response to rotation of the driving mechanism, and

- wherein the oscillatory body has a conical receptacle for receiving an output drive;
- a fixed housing;
- the fixed housing including the bearing;
- and
- the bearing being configured so that the bearing is stationary with respect to the fixed housing during the rolling of the oscillatory body on the bearing.
A gear stage of an actuating drive that includes a driving mechanism, the gear stage comprising:
- a fixed housing including a bearing defining an axis;
- and
- an oscillatory body defining an axis that is oblique to the axis of the bearing, the oscillatory body having an interior surface that extends around and along the axis of the oscillatory body to define a receptacle of the oscillatory body, the oscillatory body having a length that extends along the axis of the oscillatory body, the oscillatory body having a diameter that extends crosswise to the axis of the oscillatory body, and the oscillatory body engaging the bearing in a manner so that
- the oscillator body is for rolling on the bearing at two contact points in response to rotation of the driving mechanism,
- the oscillatory body rotates around both the axis of the bearing and the axis of the oscillatory body during the rolling of the oscillatory body on the bearing at the two contact points, and
- the rolling of the oscillatory body on the bearing at the two contact points defines a rotating eccentricity of the oscillatory body,
- wherein the oscillatory body engaging the bearing consists essentially of the oscillatory body engaging the bearing at the two contact points, and the two contact points are spaced apart from one another,
- wherein each of the two contact points is adapted for circulating during the rolling of the oscillatory body on the bearing, and
- wherein the bearing is configured so that the bearing is stationary with respect to the fixed housing during the rolling of the oscillatory body on the bearing at the two contact points.
