针对主轴轴承高速运转时产生大量摩擦热，温度分布发生变化，使轴承零件产生热位移，对机床加工精度有显著影响的问题，研究了主轴轴承的温度分布规律，并对运行工况下主轴轴承的温度分布状态进行了研究，通过对主轴轴承温度场的仿真研究，实现了轴承温度场的重建。对温度测点的布置方案进行了优化，形成了轴承温度场的测量原理和方法。

Bearing is an important part of mechanical equipment.In the spindle system, great frictional heat generates during the high-speed operation.Thermal displacement of the bearing parts is caused by the change of temperature distribution, and has a significant impact on the machining accuracy.Temperature distribution of spindle bearings was researched.And the tem-perature distribution of spindle bearings in operating conditions was studied.The reconstruction of bearing temperature field was achieved by the simulation study of spindle bearing temperature field.And layout scheme of temperature measuring points was op-timized.
