AI Technical Summary

Technical Problem

In existing high-speed thrust ball bearings, the lubricating oil is easily thrown away from the friction surface of the rolling elements under high-speed operation, resulting in uneven lubrication and affecting the operating stability and life of the bearing.

Method used

A novel high-speed thrust ball bearing cage was designed, comprising an oil injection assembly including an oil reservoir, an oil distribution pipe, and an oiling sponge. Lubricating oil is injected through the oil injection port, and the oil distribution pipe and oiling sponge are used to evenly coat the lubricating oil on the surface of the balls. A sealing assembly ensures the sealing of the lubricating oil in the oil reservoir.

Benefits of technology

This achieves continuous and uniform distribution of lubricating oil during high-speed operation, reduces frictional loss between the balls and the cage, and ensures stable operation of the bearing at high speeds.
