Description

Technical Field

[0001] This utility model relates to an oil collecting ring, specifically an oil collecting ring for the rotating shaft of a fan unit gearbox, belonging to the technical field of fan units. Background Technology

[0002] The oil collector ring on the rotating shaft of the wind turbine gearbox (hereinafter referred to as "wind turbine gearbox oil collector ring") is a key lubrication control and sealing auxiliary component on the rotating shaft (such as input shaft, output shaft, and intermediate shaft) of the wind turbine transmission system (especially wind power and industrial high-power wind turbines). Its core function is to solve the problems of "adhesion, splashing, and leakage" of lubricating oil in the gearbox caused by shaft rotation, ensure the recycling of lubricating oil, reduce losses, and assist in protecting the shaft end seals. It is the "lubricating oil steward" that maintains the long-term stable operation of the wind turbine gearbox.

[0003] Unlike internal combustion engine piston rings (which reciprocate with the piston), the core feature of wind turbine gearbox oil collector rings is "fixed installation + adaptation to rotating shaft". The oil collector ring itself is fixed on the gearbox housing or bracket, and the inner ring is tightly fitted with the surface of the rotating shaft. Oil control is achieved through "relative movement between the fixed part and the rotating shaft". It needs to be adapted to the working requirements of wind turbine gearboxes such as "low speed, heavy load, outdoor / harsh environment, and long service life".

[0004] Traditional oil collecting rings are usually made of one piece, which makes assembly difficult and easily damages parts. To address this, a rotating shaft oil collecting ring for wind turbine gearboxes is proposed. Utility Model Content
