    摘要:

    为了提高凸轮分割器的运动精度,通过分析凸轮分割器的运动结构原理,建立凸轮分割器的凸轮滚子和锥度支撑胁在润滑过程中的磨损功率模型;通过研究凸轮分割器的凸轮滚子和锥度支撑胁轮廓表面存在的边界润滑状态,建立边界润滑中最小润滑膜厚度的数学模型,分析速度、温度、黏度对边界润滑油膜形成的影响律。提出保持凸轮分割器良好润滑环境的策略,保证边界润滑油膜能有效地形成。

    Abstract:

    In order to improve the motion accuracy of cam indexer,the model of wear power was established between the cam roller and the taper support flank after analyzing the motion structural principle in the lubrication process.Through studying the boundary lubrication between the cam roller and the surface of taper support flank,the mathematical model about the minimum film thickness of boundary lubrication was established.The effects of oil film formation were explored among the velocity,the temperature and the viscosity of boundary lubrication.The strategy was put forward to keep the good lubricating environment of cam indexer,and ensure the formation of boundary lubricant film.
