Patent ID: 8591371

Claim:
A planetary gear mechanism for a wind power plant, comprising: at least one sun gear, an internal gear and a planetary carrier, a plurality of planetary gears comprising planetary gear shafts supported in the planetary carrier, a plurality of radial slide bearings supporting the planetary gears, each radial slide bearing including a sleeve made of a slide bearing material, said sleeve being either attached as an inner ring to a planetary gear shaft or being mounted as an outer ring in a bore of a planetary gear, wherein an outer bearing ring cooperating with the inner ring is formed by the bore in the planetary gear or an inner bearing ring cooperating with the outer ring is formed by the planetary gear shaft, respectively, a plurality of axial slide bearings supporting the planetary gears, each axial slide bearing including a first bearing element made of a slide bearing material, said slide bearing material being applied to a contact face disposed between a planetary carrier cheek and an end face of a planetary gear either on the planetary carrier cheek or on the end face of the planetary gear, wherein a cooperating second bearing element is formed either by the end face of the planetary gear or by the planetary carrier cheek, respectively, an oil distributor ring which radially surrounds a shaft of the sun gear and comprises a connection to an oil supply duct in a transmission housing for pressure lubrication of the axial slide bearings or the radial slide bearings, or both, and at least one oil distribution duct disposed in the planetary carrier and connected to the oil distributor ring and terminating at a lubrication point for a planetary gear bearing.
