Planet carrier lubricating structure of wind power gear box

Abstract

The invention discloses a planet carrier lubricating structure of a wind power gear box. The structure comprises a box body, a planet carrier, a planet carrier bearing, a pin shaft, a planet wheel anda planet wheel bearing; the planet carrier is mounted on the box body through the planet carrier bearing, the pin shaft is arranged on the planet carrier, the planet wheel is mounted on the pin shaftthrough the planet wheel bearing, the pin shaft forms an oil storage groove and an oil way, and the oil way is used for guiding oil in the oil storage groove to the planet wheel bearing for lubricating the planet wheel bearing, the oil way communicates with the oil storage groove, the planet carrier is provided with an oil inlet allowing oil to enter the oil storage groove, the oil storage grooveand the oil inlet are aligned, the hole opening area of the oil storage groove is smaller than the hole opening area of the oil inlet, and the planet carrier lubricating structure of the wind power gear box further comprises an oil spraying structure for spraying oil into the oil inlet when being aligned with the oil inlet. The structure has the beneficial effects that compared with a traditionallubricating manner, the structure is simple, and machining cost is low.

Description

technical field [0001] The invention relates to a planet carrier lubricating structure, in particular to a planet carrier lubricating structure of a wind power gearbox. Background technique [0002] Wind power gearbox, also known as wind power gearbox or wind power speed increaser, is a very critical component in the whole machine, which plays a role in transmitting power in the whole machine, and its quality directly affects the safety performance and economic performance of the wind turbine. Due to the particularity of wind power, once the gearbox fails, it is difficult to disassemble it at high altitude. Therefore, once a failure occurs, it cannot be repaired at high altitude, but can only be replaced as a whole, resulting in high operating costs of wind turbines. [0003] However, when the planetary level lubrication is poor, it may cause a gearbox failure and affect the service life of the gearbox. In order to ensure reliable lubrication, the traditional lubrication st...

AI Technical Summary

Problems solved by technology

Due to the particularity of wind power, once the gearbox fails, it is difficult to disassemble it at high altitude. Therefore, once a failure occurs, it is generally impossible to repair it at high altitude and can only be replaced as a whole, resulting in high operating costs for wind turbines.

[0003] However, when planetary grade lubrication is poor, it may cause gearbox failure and affect the service life of the gearbox

In order to ensure reliable lubrication, the traditional lubrication structure has a complex structure and high processing costs
