Abstract (en)

[origin: WO2011015184A1] The invention relates to a method for producing a flanged disk (16) for a spherical roller bearing (1). According to the invention, a straight pipe section is first bent to form a ring (28) having two ring ends (29, 30) separated by a gap (31), the two ring ends (29, 30) of which ring are then joined. The therefore closed, for example welded, ring preform (28) is finally shaped into a flanged disk (16) having the desired axial section geometry (35), which generally deviates from a circular shape, in a pressing device having a suitable contour tool in a single pass. Said production process ensures a practically waste-free and energy-efficient production process of the flanged disk (16) designed as a hollow body (17), said production process having short cycle times. In addition, the flanged disk (16) has a significantly reduced mass compared to conventional flanged disks produced from solid material. Furthermore, the invention relates to a spherical roller bearing (1) having a flanged disk (16) produced according to the invention and designed as a hollow body (17).
