Description

Technical Field

[0001] This utility model relates to the field of electric spindle bearing housing cleaning technology, specifically to an integrated cleaning and circulating pump for wind turbine spindle bearing housings. Background Technology

[0002] During operation, the wind turbine main shaft bearing housing experiences rolling friction and a small amount of sliding friction between the balls and the cage, the inner ring of the bearing, and the outer ring of the bearing. After long-term operation, component wear will occur. Although an appropriate amount of grease is injected into the wind turbine main shaft bearing housing, a large amount of wear metal filings will still adhere to the grease, main shaft, balls, and other surfaces of the wind turbine main shaft bearing housing during actual operation.

[0003] Currently, the cleaning of wind turbine main shaft bearing housings mainly relies on manual disassembly, followed by the use of cleaning agents and high-pressure air blowing. This results in very high labor costs. Furthermore, the high altitude at which wind turbines operate further complicates the disassembly and cleaning of the bearing housings. As a result, the entire industry suffers from problems such as low cleaning efficiency and high labor costs. Utility Model Content
