摘要

摘要: 针对球轴承高速运转时的热生成及热边界条件问题,建立轴承拟静力学模型分析其受力状态,根据Palmgren经验公式计算轴承摩擦产热,并应用传热学理论,建立考虑热阻抗影响的脂润滑轴承热传递网络模型;研制轴承-转子系统,测量不同工况条件下的轴承外圈温度,试验结果表明:理论模型能准确预测脂润滑球轴承运转时的温升状况,误差在10%以内;轴承启动时其温度上升速度最快,轴承转速和预紧力对其最终稳态温度影响较大,需要加以合理控制。

Abstract: Considered the heat generation and thermal boundary condition of the rotating ball bearing, a quasi-staticmodel of ball bearing was established to analyze the stress state of the bearing, and the frictional heat of the bearingwas calculated by the Palmgren empirical formula. Based on heat transfer theory, a heat transfer network model,which took the thermal resistances into account, was constructed for grease-lubricated bearing. A bearing-rotorsystem was developed to measure the temperature changes of bearing outer ring in various working conditions. Theexperimental results indicate that the proposed models can effectively predict the temperature rises of rotatinggrease-lubricated ball bearings and the prediction error is less than 10%; the temperature rises quickest in setupphase of bearings; and the rotating speed and preload of bearings must require reasonable control, which have a biginfluence on the steady temperature.
