PROCESSO PARA A FABRICACAO DE GAIOLAS DE MANCAIS DE ROLAMENTO FEITAS DE CHAPAS METALICAS E GAIOLA

摘要

In the method of producing a rolling bearing cage a strip of metal (10) having recesses (12) at its ends is bent to form a ring and the abutting edges (11) are welded together to form joints (16). The recesses (12) form one or more apertures (15). Pockets (17) to receive rollers or balls are then punched out from the ring, the punch tool and the weld joints (16) not contacting each other since the pocket adjacent the joints has recesses (18) which previously formed part of the aperture(s) (15). Thus only short weld joints (16) are required.
