摘要

摘要: 将滚子与套圈滚道摩擦生热视为移动热源,建立了高速圆柱滚子轴承温度场计算模型;使用ANSYS的APDL语言发展了轴承工作温度分析的参数化程序,输入热流密度等边界条件,程序能够自动建模精确的分析高速圆柱滚子轴承工作温度.以一个型号轴承为例,分析了不同工况参数对轴承工作温度的影响,结果显示轴承内圈转速、径向载荷和润滑油入口油温对轴承工作温度影响显著.

Abstract: Heat generation between rollers and raceways treated as moving heat source,a model for calculating the temperature field of a high-speed cylindrical roller bearing was set up.Aparametrical code has been developed with the APDLlanguage of ANSYS.Using this code,the operating temperature of cylindrical roller bearings with different types of lubricants can be obtained more accurately when boundary conditions such as heat flux are input.Taking one model of bearing as an example,effects of various operating parameters on operating temperature have been analyzed.It is shown that the rotational speed of the inner ring,the radial load and the inlet temperature of the lubricant have a great influence on operating temperature of the bearing.
