PLANETARY GEAR MECHANISM WITH A SLIDING BEARING ASSEMBLY, IN PARTICULAR FOR A PLANETARY GEAR BEARING SYSTEM IN A TRANSMISSION OF A WIND TURBINE

摘要

The invention relates to a planetary gear mechanism stage having a sliding bearing arrangement (10; 10a-10e), in particular for a planetary gear bearing, comprising at least three planetary gear shafts (11), on each of which at least one planetary gear (12) is rotatably mounted by means of the sliding bearing arrangement (10; 10a-10e) which has a bearing bushing unit which is mounted on the respective planetary gear shaft (11) and has the purpose of providing combined axial and radial bearing for the planetary gear (12), wherein the bearing bushing unit comprises a pair of conical bearing rings (100a, 100b - 500a, 500b) which each have a cylindrical inner face (110) and an outer face (120) which runs obliquely with respect to the latter, wherein the inner face (110) comes dressed on the planetary gear shaft (11) or on at least one inner sliding bearing bushing (510a, 510b) which is mounted thereon, and the outer face (120) interacts with a bearing face, shaped so as to correspond to the latter, on the planetary gear (12) for forming a sliding bearing.
