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).
Claims21
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 oscillatory body being mounted
- for rolling on the bearing in response to rotation of the driving mechanism, and
- so that 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.
The gear stage as claimed in claim I in combination with both the driving mechanism, which is for driving the rolling of the oscillatory body on the bearing, and an output drive operatively connected to the oscillatory body for being driven by the rolling of the oscillatory body on the bearing, whereby the combination is the actuating drive.
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 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 being mounted
- for rolling on the bearing in response to rotation of the driving mechanism,
- so that 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,
- so that the rolling of the oscillatory body on the bearing defines a rotating eccentricity of the oscillatory body, and
- so that the oscillatory body engages the bearing at two contact points, the two contact points being spaced apart from one another along the length of the oscillatory body, and the two contact points being substantially diametrically opposite one another with respect to the diameter of the oscillatory body.
