SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a wind-powered electricity generation gear box planet carrier structure has the advantage of convenient assembly avoiding the lubricating oil seepage again.
The technical scheme is as follows: the utility model discloses a planet carrier structure of a wind power gear box, which comprises a frame body with an axial hole and an annular oil inlet ring arranged on the axial end face of the frame body; the frame body is provided with an oil inlet assembly on the axial hole, the oil inlet assembly comprises an oil inlet nozzle penetrating through the axial hole, and the inlet part of the oil inlet nozzle is embedded into the annular oil inlet ring.
The oil inlet assembly further comprises a sealing ring used for sealing a gap between the axial hole and the oil inlet nozzle.
By adopting the technical scheme, one end of the oil inlet nozzle is embedded into the planet shaft, the other end of the oil inlet nozzle is inserted into the annular oil inlet ring, and the oil inlet nozzle and the axial hole of the frame body are in transition fit to reduce the fit clearance; a gasket is additionally arranged between the annular oil inlet ring and the oil inlet nozzle, so that the compression state between the oil inlet nozzle and the axial hole of the frame body can be conveniently adjusted, and the looseness of the oil inlet nozzle and the axial hole of the frame body is avoided. Lubricating oil enters from the annular groove of the annular oil inlet ring and then enters the oil inlet nozzle; and the lubricating oil flows to the planetary shaft holes and the oil spray holes on the distance rings through the oil inlet nozzles and finally enters the bearings for lubrication.
Has the advantages that: the oil inlet nozzle is tightly attached to the axial end face of the annular oil inlet ring, and the assembly gap between the oil inlet nozzle and the axial hole of the planet carrier is sealed, so that oil leakage is reduced, the bearing is ensured to work in a sufficient lubricating environment, and the service life of the bearing is prolonged.
