基于ANSYAS的深沟球轴承有限元分析

Finite Element Analysis of Deep Groove Ball Bearings Based on ANSYAS

摘要: 本文选用深沟球轴承为研究对象，在UG软件中建立深沟球轴承的三维实体模型，并将建立的模型导出为stp格式，再导入ANSYS软件中，进行瞬态强度分析。仿真结果表明：深沟球轴承的变形、等效应力、等效应力强度主要分布在滚珠与保持架接触的位置；深沟球轴承内外圈所受的应力值很小；深沟球轴承的内外圈，保持架以及滚珠对应的变形量均有所不同。该研究为深沟球轴承的结构设计提供一种新的参考。

Abstract: This article selects deep groove ball bearings as the research object. A three-dimensional solid model of the deep groove ball bearing is established in UG software, and the established model is exported to stp format and then imported into ANSYS software for transient strength analysis. The simulation results show that the deformation, equivalent stress, and equivalent stress intensity of the deep groove ball bearing are mainly distributed at the contact position between the ball and the cage. The stress values on the inner and outer rings of the deep groove ball bearing are very small. The deformation of the inner and outer rings of the deep groove ball bearing, the cage, and the balls are all different. This study provides a new reference for the structural design of deep groove ball bearings.
