圆锥滚子轴承最小油沟尺寸设计

Dimensional Design of Minimum Oil Groove for Tapered Roller Bearings

通过理论计算和有限元法分析了油沟尺寸对轴承整体性能的影响,结果表明油沟尺寸越小越好,同时指出原油沟加工方法加工小尺寸油沟的难题,对油沟加工方法进行改进,并通过分析得到了最小油沟尺寸的计算方法。

The influence of dimension for oil groove on overall performance of tapered roller bearings is analyzed through theoretical calculation and finite element method,and the results show that the dimension for oil groove should be as small as possible.The difficulty is pointed out for processing of small-sized oil groove by original method,and the method is improved for processing of oil groove.The calculation method for dimension of minimum oil groove is obtained through analysis.
