高耐磨异型机械组件微孔润滑结构
By designing an oil outlet and oil reservoir structure within the cage in a non-standard mechanical component, and utilizing the cooperation of steel balls and connecting rods, automatic replenishment and uniform distribution of lubricating oil are achieved. This solves the problems of lubricant depletion and uneven distribution at high speeds or high temperatures, thereby improving lubrication performance and bearing life.

AI Technical Summary
The lubrication effect of existing irregularly shaped mechanical components relies on the fixed lubricant embedded in the oil hole. Under high speed or high temperature conditions, the lubricant may be depleted prematurely, and after long-term operation, the lubricant may be unevenly distributed, causing local dry friction.
A microporous lubrication structure for highly wear-resistant irregularly shaped mechanical components was designed. The structure features an oil outlet and an oil reservoir within the cage. Through the cooperation of steel balls and connecting rods, centripetal force is used to achieve automatic replenishment and uniform distribution of lubricating oil, thus preventing lubricant depletion.
It effectively reduces the friction coefficient of the bearing, improves the lubrication effect, extends the service life of the bearing, and prevents the lubricant from being depleted prematurely or unevenly distributed under high temperature or high speed.
