摘　　要：高速磨削电主轴的温升对电主轴的加工精度和使用寿命有着重要的影响。以SPM170高速磨削电主轴为研究对象,采用理论分析和试验验证的方法对高速磨削电主轴的冷却系统进行了研究。通过分析可知电主轴电机部分的产热主要是由铁芯损耗产生的,水冷系统可以有效地带走电机部分的热量,使电主轴的温升降低。对SPM170高速磨削电主轴的冷却系统进行了改进,设计了一种新型螺旋水道,在电主轴最高工作转速时,分别测量电主轴前轴承壳体温度,并对比其温升。结果表明:采用改进之后的螺旋水冷装置电主轴的温升比改进前温升降低了10℃左右,温升得到了有效的控制。Temperature rise of high-speed grinding spindle has an important impact on machining accuracy and service life of the electric spindle. The SPM170 high-speed grinding spindle was taken for the study object. Cooling system of the high-speed grinding spindle improvements was studied by using the method of theoretical analysis plus test certifying. It was known by analyzing that the heat was generated mainly of the electric spindle motor by the iron core loss,and the heat of motor part could be effectively removed by the cooling system,which led the electric spindle temperature decrease. The new spiral waterways were designed of SPM170 highspeed grinding spindle cooling system for its improvements and upgrade. The results show that after improvement of the spiral waterway cooling device,the temeperature rise of electric spindle is reduced for about 10 ℃,for which is effectively controlled.
