- the sliding ring facing surface of the circumferential dome portion of the calotte-like disengagement ring is roughened.
- this has a knurling.
- a knurling is understood to mean a material processing in which a pattern is embossed in the circumferential dome section. Compared to smooth surfaces such grip surfaces allow a better connection of the slide ring with the dome-like release ring.
- a further development of the invention relates to a method for producing a shock-absorbing bearing for a self-adjusting release bearing in which a slip ring is applied to a dome-like release ring.
- the impact compensation bearing can be produced inexpensively, the dome-like release ring made of steel is punched out of a sheet metal and then the slip ring is clipped into the calotte-like release ring or welded by means of ultrasound.
- This has the advantage that a cost reduction in the production of impact compensation bearing is possible, which is not only due to the use of a sheet, but also due to a reduced mechanical reworking on the punched dome-like release ring.
- a stamped-out support ring of the dome-like release ring is turned off in a predetermined height. Due to this turning process, it is easily possible, depending on the application of the shock-absorbing bearing to adjust this to a predetermined height, so that its dimensions well with the space to match, which provides the release bearing comprehensive coupling.
- a circumferential Kalottenab mustard the calotte-like release ring is rotated in a predetermined shape and then knurled.
- the dimensions of the circumferential dome section of the dome-like disengagement ring are adjusted, while the knurling process roughens the surface of the dome section which receives the slip ring in order to realize an anti-rotation lock of the slide ring formed of plastic.
