摘要

柔轮是谐波齿轮传动中的关键核心部件,其性能直接决定了谐波传动的整体状况,为了探求柔轮壁厚对其性能影响的基本规律,从而能够更好的控制其性能。采用ANSYS Workbench软件分别对其空载及负载状态下柔轮壁厚对其应力及变形的影响情况进行仿真分析,结果表明,在空载情况下随着壁厚的增加,柔轮的最大应力不断增强,最大变形整体减小;在负载情况下,随着柔轮壁厚的不断增加,柔轮的最大应力整体减小,最大变形先减弱,后趋于平缓,在相同壁厚下,随着负载的增加,最大应力与最大变形均增加,随着壁厚的减小,负载对变形的影响越来越敏感;在相同条件下,筒底修型比等壁厚结构的柔轮所产生的应力较小。柔轮壁厚对其性能影响的这一规律为相关研究人员提供一定的参考。

Abstract

The flexible gear is the key parts of harmonic gear reducers,and its performance directly determine the overall condition of harmonic drives. In order to seek the basic law of influence of flexible gears wall thickness on its performance to make use of the law,the influences of flexible gears wall thickness on stress and deformation of the flexible gears are simulated and analyzed by ANSYS Workbench software under no-load and load conditions. The results show that,the maximum stress of the flexible gear increases and the maximum deformation decreases with the increase of the wall thickness under no-load condition. With the increase of the wall thickness,under the load condition,the maximum stress decreases overall and the maximum deformation decreases first and then tends to be gentle. Under the same wall thickness,with the increase of the load,the maximum stress and the maximum deformation both enhance and the load is more sensitive to the deformation in the places whose wall thickness are relatively thinner. Under the same conditions,the stress of flexible gear with bottom modification is smaller. This law can provide some reference for researchers.
