摘要
为精确预测高速角接触球轴承在实际工况下的温升,通过对角接触球轴承的生热机理分析,提出一种考虑接触参数与摩擦生热交互影响的高速角接触球轴承温升预测方法。利用Abaqus有限元软件脚本接口技术,自主编制Python脚本程序,实时提取受载的角接触轴承的接触参数为初始量,计算轴承摩擦生热量,将其作为时变热载荷,加载至有限元模型上,求解在径向载荷和转速作用下的高速角接触球轴承温升,得到接触参数、摩擦生热量、温升之间的相互影响关系,最后采用轴承温升实验对数值模拟结果进行验证。结果表明:考虑接触参数与摩擦生热交互影响下的高速角接触球轴承温升预测方法更符合实际工况。
A new method of is put forward for predicting accurately the temperature rise of high-speed angular contact ball bearing considering the interaction between contact parameters and frictional heat generation under the actual working state in this paper. The contact parameters, of which the loaded angular contact ball bearings are read from the extracted code in real time using the Python script independently compiled with Abaqus software, is the initial variables to calculate the bearing friction heat generation. It is used as a time-varying thermal loads to the finite element model for solving the temperature rise of high-speed angular contact ball bearings under the radial load and rotation speed. Finally, the interactions of the contact parameters, frictional heat generation, and temperature rise can be received. The result shows that the method of predicting the temperature rise of high-speed angular contact ball bearings under the interaction of contact parameters and frictional heat generation is more in line with the actual working conditions.
