摘　　要：在航空发动机中,滑油系统主要发热由轴承摩擦引起。由此,对航空发动机轴承腔温度影响因素进行分析。通过轴承建模,对轴承在不同载荷和转速时的工作情况进行数值计算,对比分析不同因素对轴承腔温度变化的影响。通过分析,为航空发动机滑油系统的热平衡提供理论支撑。In the aircraft engine,the main source of heat generation in lubrication system is due to bearing friction.Thus,an analysis was conducted on the influence factor on the temperature in bearing chamber of the aircraft engine.By establishing the bearing model,numerical calculations were performed on the working conditions of bearing under different loads and speeds,and the influence of different factors on the temperature change in bearing chamber was compared and analyzed.Through analysis,the theoretical support for the thermal balance of lubrication system in the aircraft engine was provided.
