摘　　要：在分析摆动活齿传动的啮合原理和载荷分布的基础上,应用弹性流体动力润滑理论对摆动活齿传动进行了研究,分析了该种传动所处的润滑状态,揭示了油膜厚度的分布规律,讨论了最小油膜厚度的影响因素。结果表明活齿与激波器啮合处,主要处于刚性-变粘度润滑区,而活齿与内齿圈啮合处,主要处于弹性-变粘度润滑区;在摆动活齿传动中,在活齿啮入、啮出以及齿圈曲线拐点附近,油膜厚度较小,容易发生磨损、胶合;摆动活齿传动低副等效机构的机构参数对油膜厚度分布和最小油膜厚度都存在不同程度的影响。在允许范围内,适当调整摆动活齿传动等效机构参数,有利于啮合副油膜的形成并可增大最小油膜厚度,从而提高摆动活齿传动的承载能力。Based on analysis of engaging theory and load distribution for swing movable teeth drive, the elastohydrodynamic lubrication theory was applied to study swing movable teeth transmission. The elastohydrodynamic lubrication condition for the drive was analyzed and oil film thickness distributions and their affecting factors were described. Several conclusions are drawn: the mesh point between the movable teeth drive and the surge wheel is in rigid and variable viscosity lubrication condition, and the mesh point between the movable teeth drive and the internal gear is in elastic and variable viscosity lubrication condition. There is less oil film thickness in the area of starting and ending engages of the movable teeth, then the binding and abrading failure is apt to occur in this field. All structural parameters of the swing movable teeth drive can influence the oil film thickness distributions.
