摘要
运用流体动力润滑理论分析了油膜均衡行垦齿轮间载荷的机理，解释了共转滑动轴承的动态特性。利用数值方法求解了Ｒｅｖｎｏｌｄｓ方程。计算结果和试验结果有良好的一致性，并表明：共转滑动轴承的油膜柔度随载荷的增大而减小；随轴承间隙的增大而增大；随转速的增大而减小。
In this paper,the principle of equilibrating loads in planetary gears is analysed by oil film calculation,and the dynamics characteristics of co-rotating bearing(its bush rotates with journal rotating)are explained by hydrodynamics theory.The analysis results show that the co-rotating bearing has a higher load capability and a larger flexibility of oil film. The Reynolds Equation is solved by numerical method, and results are shown by curves.The experimental in-vestigation on co-rotating beariiig is made,and expcrimental results show that the oil film flexi-bility decreases as the bedring load increases,the flexibility increases as the bearing clearanee in-creases and decreases as bearing rotation rate increases.The experimental investigation on load equilibrating is made in a planetary reducer,and results show that loads among planet gears get agood distribution by using co-rotating bearing.
