摘要

介绍了肖南平先生提出并获得发明专利的一种新型少齿差行星减速器的结构组成,利用ANSYS Workbench软件建立此减速器箱体的有限元模型。对箱体各实际受载情况进行静力学分析,得出箱体所受最大应力和变形量的变化曲线,为箱体结构后续结构改进和轻量化设计提供相关分析数据。对箱体进行有限元模态分析,得到箱体固有频率及相应振型,将其与减速器的转频和啮合频率进行对比分析,可确定减速器是否会发生共振现象。对相应振型的分析为减速器结构的优化设计及振动问题提供理论依据。

Abstract

The structure of the new-type of the planetary reducer with few teeth difference,which is proposed by Xiao Nanping and received the patent for this invention are introduced. The finite element model of this reducer box is established by using the software ANSYS Workbench. The statics analysis is carried out,the changing curve for each actual loading conditions of the reducer box,and the changing curve of the maximum stress and the deformation are obtained,this analysis results can provide the data support for the subsequent structure improvement and weight reduction. The natural frequency and vibration type are obtained by completing the modal analysis of this box,and whether the resonance phenomenon happens can be determined by comparing the natural frequency of this reducer with the meshing frequency and the rotational frequency. It also offers a theoretic reference for the structure optimization design and following research of vibration problems for reducers.
