摘要
微型深沟球轴承广泛应用于小型工业装备、小型回转电机、玩具等相关领域。针对儿童轮滑鞋用608zz微型深沟球轴承,采用Creo软件建立三维实体模型,运用ABAQUS动力隐式算法对轴承接触情况进行了模拟分析,获得了依据实际工况确定的径向载荷及转速情况下的接触应力分布和最大接触应力。结果表明:最大接触应力随径向载荷和转速增加而增大,最大接触力分布在滚动体上,与实际情况一致,可为轴承设计提供参考。
Miniature deep groove ball bearings are widely used in small industrial equipment, small rotary motors, toys and other related fields. In this paper, a three-dimensional solid model of 608zz miniature deep groove ball bearing used in children’s roller skates was established by Creo software, and the contact situation of the bearing was simulated and analyzed by ABAQUS dynamic implicit algorithm. The contact stress distribution and maximum contact stress under radial load and rotational speed determined according to the actual working conditions were obtained. The results show that the maximum contact stress increases with the increase of radial load and rotational speed, and the maximum contact stress is distributed on the rolling body, which is consistent with the actual situation and can provide reference for bearing design.
