ABSTRACT:
The invention relates to a method of producing a cage for constant velocity universal joints. The method involves a chipless forming operation. The method improves radial guidance of the balls by using larger window faces which are also produced in a chipless way. In a first step, starting from a circular plate metal blank, a dish with a rim is deep-drawn. At the same time, projections are formed which are circumferentially distributed along the inner and/or outer circumference of the dish in accordance with to be produced windows. The projections are directed inwardly and outwardly, respectively, away from the longitudinal axis. Also, starting from the dish opening, the projections extend over a distance which is greater than the width of the to be formed windows. In a second step, the base of the dish and the rim, either simultaneously or successively, are punched out while leaving parts to form the projections at the outer circumference. In a third step, either simultaneously or successively, the outwardly directed projections and the guiding face are transferred into their finished condition by profile stamping, and in a further step, the windows are punched out.
