Cage for e.g. retaining rollers of double-row taper roller bearing of wind power plant, has guide elements formed in side plates or non-perforated rollers for guiding rollers, where guide elements are formed as single-piece element

摘要

The cage has perforated rollers (4) and non-perforated rollers (6) arranged between an outer ring and an inner ring (3), and two cage side plates (8) connected with each other by three bearing bolts (9). The perforated rollers are rotatably supported in the bearing bolts. The non-perforated rollers are arranged between the perforated rollers and guided to the side plates at a distance to each other. Guide elements (7) are formed in the side plates or the non-perforated rollers for guiding the non-perforated rollers and formed as a single-piece element with homogenous material.
