Abstract

The invention relates to a compensation apparatus for compensating for thermally induced relative axial positional changes between two components, having a first compensation part which brings about an axial temperature-compensating movement of one of the compensation parts via a conical sliding face in a corresponding recess of a second compensation part if the radial extent of at least one of the compensation parts changes in a temperature-induced manner. In order to optimize the compensation capability of this apparatus, and to make it as far as possible independent of production tolerances of its installation surroundings with particularly simple means, there is provision for at least one compensation part to have a joint with a joint width which is variable during operation and imparts mechanical radial spring properties to the compensation part.

Claims (4)

1. A compensation apparatus for compensating for thermally induced relative axial positional changes between two components, comprising: a first compensation part and a second compensation part wherein an axial temperature-compensating movement of one of the compensation parts via a conical sliding face in a corresponding recess of the second compensation part if the radial extent of at least one of the compensation parts changes in a temperature-induced manner, wherein at least one compensation part has a joint with a joint width which is variable during operation and imparts mechanical radial spring properties to the compensation part.

2. The apparatus of claim 1 , wherein the compensation part is a resilient configuration and is held in a receptacle under resilient prestress.

3. The apparatus of claim 1 wherein both compensation parts are composed of steel.

4. The apparatus of claim 1 , wherein one of the compensation parts has an axial slot.
