Embodiment Construction
[0034] figure 1 Shown is a rolling bearing cage 12 constructed according to the invention, which is milled out of a ring-shaped solid part. A multi-axis milling machine is used for this, which mills out the cage pockets 8 so that the side rings 2 are fixedly coupled to one another via a plurality of cage connecting beams 1 .
[0035] Rolling bearing cage 12 can be found in figure 2 It is clearly seen in the longitudinal section of the . The conical rolling bodies 9 are inserted into the cage pockets 8 , which in a known manner pass through the cage pockets 8 with only a part of their diameter. in sight Figure X The fully visible cage pocket 8 shown in , has pocket corners 10 that can be considered partially elliptical or partially sports-field-like in the region where the cage connecting beam 1 is connected to the two side rings 2 . These pocket corners 10 are shaped and in particular radially formed in such a way that the rolling bodies accommodated in the cage pockets ...
