Abstract

A slide bearing bush with an integrated sealing element permits a relatively simple and economical production of the slide bearing bush. The slide bearing bush includes a bush part and a cover part. The bush part and/or the cover part is provided with an annular groove formed for holding the sealing element, and the slide bearing bush comprised of the bush part and the cover part possesses a cylindrical outside contour.

Claims (10)

1. A slide bearing bush mounted on a shaft, the slide bearing bush possessing a cylindrical outer contour, the slide bearing bush comprising a bush part and a cover part, the bush part being provided with a through hole possessing an inner surface facing an outer periphery of the shaft, the bush part including an annular groove, the cover part being connected to the bush part so that a portion of the cover part bounds the annular groove and defines a wall of the annular groove, a sealing element positioned in the annular groove, the bush part and the cover part each having an outer surface forming a part of the cylindrical outer contour of the slide bearing bush, the cover part being connected to the bush part by at least one projection that engages at least one recess having an undercut, the projection having an axially extending part and a radially extending hooked-shaped part positioned in the recess, the projection and the recess forming a snap connection, the projection having a radial outer surface forming a part of the cylindrical outer contour of the slide bearing bush, the recess having opposing surfaces facing one another, and the cover part comprises a radially outwardly directed mounting flange.

2. A slide bearing bush mounted on a shaft according to claim 1 , wherein the projection is integrally formed with the cover part, and the recess is formed in the bush part.

3. Slide bearing bush as claimed in claim 1 , wherein the bush part and cover part possesses a cylindrical inside contour.

4. Slide bearing bush as claimed in claim 1 , wherein at least the bush part is made of plastic.

5. Slide bearing bush as claimed in claim 1 , wherein the bush part and the cover part are made of plastic.

6. Slide bearing bush as claimed in claim 1 , wherein the cover part is made of plastic and the bush part is made of metal or a fiber composite or of a combination of these materials.

7. Slide bearing bush as claimed in claim 1 , wherein the annular groove receiving the sealing element possesses a rectangular shape in radial cross-section.

8. A slide bearing bush mounted on a shaft, the slide bearing bush possessing a cylindrical outer contour, the slide bearing bush comprising a bush part and a cover part, the bush part being provided with a through hole possessing an inner surface facing an outer periphery of the shaft, the bush part including an annular groove, the cover part being connected to the bush part so that a portion of the cover part bounds the annular groove and defines a wall of the annular groove, a sealing element positioned in the annular groove, the bush part and the cover part each having an outer surface forming a part of the cylindrical outer contour of the slide bearing bush, the cover part being connected to the bush part by at least one projection that engages at least one recess having an undercut, the projection having an axially extending part and a radially extending hooked-shaped part positioned in the recess, the projection and the recess forming a snap connection, the projection having a radial outer surface forming a part of the cylindrical outer contour of the slide bearing bush, and the cover part comprises a radially outwardly directed mounting flange, wherein a first wall of the recess faces a first wall of the radially extending part, a second wall of the recess faces a second wall of the radially extending part and a third wall of the recess faces a third wall of the radially extending part.

9. Slide bearing bush as claimed in claim 8 , wherein the first wall of the recess intersects the second wall of the recess and the third wall of the recess.

10. A slide bearing bush mounted on a shaft, the slide bearing bush possessing a cylindrical outer contour, the slide bearing bush comprising a bush part and a cover part, the bush part being provided with a through hole possessing an inner surface facing an outer periphery of the shaft, the bush part including an annular groove, the cover part being connected to the bush part so that a portion of the cover part bounds the annular groove and defines a wall of the annular groove, a sealing element positioned in the annular groove, the bush part and the cover part each having an outer surface forming a part of the cylindrical outer contour of the slide bearing bush, the cover part being connected to the bush part by at least one projection that engages at least one recess having an undercut, the projection having an axially extending part and a radially extending hooked-shaped part positioned in the recess, the projection and the recess forming a snap connection, the projection having a radial outer surface forming a part of the cylindrical outer contour of the slide bearing bush, and the cover part comprises a radially outwardly directed mounting flange, wherein a portion of the outer contour of the bush part is the same radial distance from the shaft as a portion of the outer contour of the cover part.
