Friction bearing arrangement of a rotary element on a bolt, in particular of a planetary wheel on a planetary wheel bolt of a planetary wheel transmission

摘要

Friction bearing arrangement of a rotating element on a bolt, comprising a bearing bolt (2), which has at least one lubricant channel (11) leading to the outer side of the bolt, a bearing bushing (4) fixedly arranged against rotation in it with a first rolling surface (6) configured on the outer periphery, and a rotating element (3) rotatably housed on the bearing bushing (4) with a second rolling surface (7) configured in the inner periphery, which is housed sliding on the first rolling surface (6), characterized in that the bearing bushing (4) has a radial groove (12) configured in the inner periphery, which communicates with the radial lubricant channel ( 11), and at least one through hole (14) open towards the rotating element (3), which is derived from it, and because the rotating element (3) has a radial groove (17) configured in the inner periphery and what was common Unique with the through hole (14), the first rolling surface (6) being harder than the second rolling surface (7).
