Title:
WIND MOTOR GEARBOX LUBRICATING APPARATUS AND GEARBOX
Document Type and Number:
WIPO Patent Application WO/2024/083253
Kind Code:
A1
Abstract:
A wind motor gearbox lubricating apparatus, wherein a shaft inner tube is arranged in a driving shaft and a driven shaft, an annular flow channel is formed by the shaft inner tube and the driving shaft, and lubricating oil is provided in the annular flow channel. The lubricating oil in the annular flow channel can flow to flexible splines through the lubricating oil flow channel, so as to achieve lubrication and cooling between spline teeth. Since the lubricating oil flows outwards in the radial direction during lubrication, the lubricating oil can also provide sufficient lubrication for the spline teeth when a wind motor rotates at a high speed, preventing abrasion and failure of the flexible splines, and extending the service life of a gearbox. Also provided is a wind motor gearbox.
