Friction Power Loss of Swing Movable Teeth Transmission under Elastohydrodynamic Lubrication

摘要

摘要: 为了准确获得弹流润滑下摆动活齿传动的摩擦功率损失，根据摆动活齿传动的啮合原理，探讨了弹流润滑状态下，活齿与内齿圈之间滑动摩擦因数的计算方法，分析了传动过程中滑动摩擦因数的时变规律.在对活齿与内齿圈间的接触正压力和相对速度进行计算的基础上，建立了弹流润滑下，摆动活齿传动在一个啮合周期内不同啮合点处的瞬时滑动摩擦功率损失的计算模型.应用最小二乘法拟合了啮合周期内的瞬时滑动摩擦功率损失函数，通过对其进行积分运算导出了平均滑动摩擦功率损失的计算公式.实例计算表明：本文提出的摆动活齿传动啮合过程摩擦功耗的计算模型是可行的，当活齿与内齿圈在齿廓曲线拐点处啮合时，瞬时滑动摩擦功率损失最大，其值为118.4 W.

Abstract: To obtain the sliding friction power loss of swing movable teeth transmission under elastohydrodynamic lubrication accurately, the calculation method of the sliding friction coefficient between movable teeth and the internal gear under elastohydrodynamic lubrication was discussed, and the time-varying law of the sliding friction coefficient in the transmission process was analyzed, according to the meshing principle of swing movable teeth transmission. Then, a calculation model for the instantaneous sliding friction power loss of each point in a meshing period of the transmission under elastohydrodynamic lubrication was built, which is based on the analysis of the normal contact pressure and the sliding velocities between movable teeth and the internal gear. In this model, the function of instantaneous sliding friction power loss in a meshing period was established by the least square fitting method; by integrating the function, the calculation formulae of the average sliding friction power loss were derived. The results of a case study show that the calculation model of frictional power loss is feasible, and the instantaneous sliding friction power loss at the inflection point of internal gear profile curve reaches the maximum value of 118.4 W.
