摘要: A multi-stage planetary transmission for a wind turbine includes a transmission housing having an oil supply channel disposed therein; an input-side first planetary stage disposed in the transmission housing; at least one second planetary stage disposed downstream of and connected to the first planetary stage by a spline of a sun gear shaft of the first planetary stage; a first oil conducting channel supplied by the oil supply channel and configured to supply oil to planetary gear bearings of the first planetary stage; a second oil conducting channel supplied by the oil supply channel and disposed so as to pass through a planet carrier of the second planetary stage at least partially in an axial direction, the second oil conducting channel configured to supply oil to planetary gear bearings of the second planetary stage; and a third oil conducting channel supplied by the oil supply channel.
