slip bearing bushing, use and manufacture of a slip bearing bushing

摘要

BEARING BUSHING, USING AND MANUFACTURING A BEARING BUSHING. The invention relates to a sleeve bearing bush (1) with at least one thrust disk (10), wherein the sleeve bearing bush (1) and the thrust disk (10) have respectively a steel back (2, 11) and at least one sliding layer (3, 12). The thrust disk (10) is made in one or more parts and on the front side (4) of the sleeve bearing bushing (1) the thrust disk (10) is fixed by laser welding. The process for manufacturing hitch bushings! with at least one one-part or several-part thrust disc (10) provides for the following steps: calendering of a steel plate with at least one sliding layer (3) to form a slip bearing (1), manufacture of a one or more part thrust disc (10) from a steel strip with at least one slip layer (12) sliding bearing bushing (1) in a clamping device (20) in which the bearing bushing! (1) reaches its definitive diameter, placing and securing the thrust disk (10) on the front side (4) of the sleeve bearing bushing (1), welding the thrust disk (10) with the bearing bushing! (1) by means of a laser beam (25) and withdrawing the sleeve bearing bushing (1) from the clamping device.
