Planetary gear, in particular fûr a wind power plant with a supply of lubricating oil in a planet spider designed to bearing points

摘要

The present invention relates to a planetary gear with at least one planetary stage, comprising a cast planet carrier (4) with a plurality of planet gears arranged around the periphery of the bolt holes (9) for the accommodation of the planet pins (10) for pinion (5) of planetary gears (2), the toothing of at least with the toothing of a central sun gear (6), in the planet carrier (4) a plurality of channel sections (11a, 11b, 11c) for the supply of lubricating oil to the planet bearings (5) are formed, wherein at least one radially between the planet bolt bore (9) and a the sun wheel bearing (7a, 7b) which receives the sun wheel shafts bore (12) in the planet carrier (4) a first channel section (11a) by means of a in the planet carrier (4) integrally moulded part made of metal tube.
