联合载荷下角接触球轴承静态接触特性分析

摘要

针对角接触球轴承结构进行静态接触特性分析,研究了联合载荷对结构接触特性的影响机制.依据赫兹接触理论,设定了求解接触应力与接触角的计算方法;利用ANSYS软件建立了角接触球轴承结构模型,并提出了加载方案及约束的设定方法;将仿真结果与赫兹理论结果进行对比,验证了本文建模方法、加载方式的正确性.最后,利用本文模型探讨了联合载荷下的接触应力、接触应变、接触角、接触椭圆的变化规律及影响,为复杂加载工况下轴承的设计及应用提供工程分析参考.%The static contact characteristic of the angular contact ball bearing is analyzed and the influence mechanism of load is studied when the bearing is under combined loads.The solution of the loads and contact angles is put forward in combination with Hertz contact theory.The finite element model is established in ANSYS.The distribution and transformation law of the contact parameters under combined loads are explored.The simulation results are consistent with theoretical values.It is revealed that the model and boundary conditions are correct and rational.The changes of contact stress, contact strain, contact angle and contact ellipse are investigated.This study may provide engineering analysis reference for the design and application of rolling bearing under complex loading conditions.
