摘要：

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.
