对摆线针轮线接触弹流润滑进行数值分析，得出啮合过程中最小膜厚，与经验公式对比，验证模型的正确性。以摆线轮θ＝arccosK1处润滑状态作为判断依据，研究载荷、转速和流变指数对摆线针轮传动润滑状态的影响规律。结果表明：随着转速提高，二次压力峰高度降低并向入口区移动，膜厚相应增加；而随着载荷增加，接触区变宽，二次压力峰增加且向出口区移动，膜厚略微减小；流变指数n增加，二次压力峰先增加后减小，最后趋近于Hertz压力，并向出口区移动，膜厚相应减小。讨论了短幅系数k1对润滑的影响，表明在满足设计要求情况下，短幅系数k1减小，有利于提高润滑性能。

Numerical analysis of grease elastohydrodynamic lubrication for cycloid drives was performed.The minimum film thickness of meshing process was obtained.Comparting it with that obtained from an empirical formula,the correctness of model was verified.The average radius of cycloid wheel's lubrication state was taken as the judgment basis, the effects of rotating speed,load and rheological index on grease EHL were analyzed.Results showed that with increase in rotating speed,the second pressure peak drops and moves toward the inlet,the film thickness increases;with increase in load,the contact field width increases,the second pressure peak rises and moves toward the out let,the film thickness decreases slightly;with increase in the rhoological index n,the second pressure peak firstly increases and then decreases, finally approaches Hertz pressure,and it moves toward the outlet,the film thickness decreases.The effect of the short ampliitude coefficient k1 on lubrication was discussed,it was shown that under the conditions to meet design requirements;the decrease in k1 can improve the lubrication performance.
