摘要
建立了滚动轴承在高温热场中的保温筒有限元模型,运用ANSYS分析了其在高温场中的温度分布,并结合摩擦学和传热学理论分析其在高温场中的径向变形规律,计算其径向游隙减小量。结果表明:在高温场中,滚动轴承的径向游隙随环境温度的升高而减小,对游隙影响较大的是内圈沟道的变形,且300℃以后游隙减小量的变化趋向平缓。
A heat - preserving canister model was founded, and the temperature distribution of ball bearing in high temperature field was analyzed with ANSYS. Radial distortion rule of ball bearing in high temperature field was discussed and decrease volume of radial clearance was calculated combining tribology and calorifics theory. It is evident that in high temperature field, the radial clearance of ball bearing decreases as surrounding temperature, which is largely affected by distortion of the groove of the inner ring. And after 300 ℃, the changing trend of the decrease volume becomes calm.
