Planetary gear stage for use in planetary gear box utilized for transmitting e.g. rotational torques, has roller bearing cage for retaining rolling members, where axial length of bearing cage corresponds to width of planetary gear

摘要

The gear stage (1) has a bolt (11) for rotatably supporting a planetary gear (5) at a planetary gear carrier (3), where the bolt is arranged in a bearing bush (10). A roller bearing (13) has rolling members (15, 17) for supporting the planetary gear, where the rolling members are axially arranged at a distance from each other. A roller bearing cage (19) retains the rolling members, where axial length of the bearing cage corresponds to width of the planetary gear. The cage has a set of partial cages arranged at a distance to each other.
