【摘要】 角接触球轴承的摩擦生热引起的热变形是影响机床主轴加工精度最主要的因素,甚至引起抱轴、保持架熔化和滚道及滚动体表面损伤等失效,因此,对角接触球轴承进行热分析具有很强的理论与应用价值。本文针对机床主轴常用的角接触球轴承,建立了角接触球轴承的有限元模型,计算热载荷和边界条件,得到了温度场分布,并分析了转速对轴承温度的影响。更多还原

【Abstract】 Rotating at high speed,the angular contact ball bearing will generate large amount of friction heat in its interior,which affects rigidity and high speed performance of the bearing,even causes a variety of failure such as surface damage.The friction heat in high speed angular contact ball bearing is calculated.Finite element boundary conditions are definited to calculate the heat transfer in bearing based on the finite element methord in this paper.On the base of these,the temperature distribution in bearing is given.And the influence of different conditions including rotate speed is analysed on temperature distribution.更多还原
