Calculation and Analysis of Meshing Efficiency of the New Internal S-gears
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.
