ABSTRACT:
To seal a ball joint, a sealing bellows (3) with a bead (6) is fastened to the joint housing (1). The bead (6) is located in an L-shaped recess (4) of the joint housing (1) and is partially enclosed by an outer annular portion (8) of a retaining ring (5) deformed radially inward while an inner circular portion (7) of the retaining ring (5) engages an end surface (8) of the recess (4). To fix the sealing bellows (3) to the housing (1) in a single work step, there is machined in a cylindrical surface (12) of the L-shaped recess (4), a ring groove (11) which is engaged by an inner edge portion (10) of the inner circular portion (7) of the retaining ring (5). A tool (14) with a conical surface (15) is used for deforming of the retaining ring (5) which is advanced axially against the retaining ring (5), and the latter encloses the bead (6).
