分析了高速圆柱滚子轴承的发热因素，建立了高速圆柱滚子轴承的功率损失计算模型、热传递计算模型和热流分析模型。这些模型的建立，为定量计算轴承发热及温度分布奠定了基础。
The heating factors of high speed cylindrical roller bearing were analyzed. The power loss calculation model, heat transfer calculation model and heat flow analysis model of high speed cylindrical roller bearing were established. The establishment of these models lays the foundation for the quantitative calculation of bearing heating and temperature distribution.
