Planetary gear unit for a gearbox for a wind turbine

摘要

The present invention provides a planetary gear unit (20) for a gearbox (40) for a wind turbine. The planetary gear unit (20) comprises a housing (21) and a planet carrier (22) provided with planet shafts (23) distributed uniformly around a planet carrier's axis for rotatably supporting planet gears (24) which are mounted between a sun gear (26) and a ring gear (27) for mutual interaction and which are supported by rolling bearings (25). The planet carrier (22) is rotatably mounted in the housing (21) by means of sliding bearings (28).
