摘要

为了准确计算新型内啮合S型齿轮的啮合效率，引入了考虑轮齿表面滑差、润滑油状况及时变载荷等因素的弹流润滑时变摩擦模型；分析啮合齿面润滑机制，通过轮齿接触分析（Tooth Contact Analysis，TCA）及轮齿承载接触分析，计算了啮合齿面滑动摩擦因数及摩擦损失功率；在此基础上，获得内啮合S型齿轮啮合周期内的瞬时啮合效率和平均啮合效率，并给出了计算实例。研究结果表明，在相同设计参数下，新型内啮合S型齿轮较渐开线齿轮有更高的啮合效率；经螺旋线修形后，新型内啮合S型齿轮的啮合效率有所提高且随修形量的增大而增大。

Abstract

In order to accurately calculate the meshing efficiency of the new internal S-gears

a time-varying friction model of the elastohydrodynamic lubrication is established considering the surface sliding of the gear tooth

lubricating oil condition and load. The lubrication mechanism of the meshing tooth surface is analyzed

and the sliding friction coefficient and friction loss power are calculated by tooth contact analysis (TCA) and loaded tooth contact analysis. On this basis

instantaneous meshing efficiency and average meshing efficiency of internal S-gears within one meshing cycle are obtained. The results show that the new internal S-gears have higher meshing efficiency than the involute gears under the same design parameters. The meshing efficiency of the new internal S-gears is improved after the tooth direction modification and increases positively with the tooth direction modification.
