The Experimental Research on The Influence Factors of High Speed Spindle Temperature Rise

温升是影响电主轴工作性能的一个重要指标,为了研究水冷系统和油气润滑系统各参数对高速电主轴温升的综合影响,找出最佳工况参数。采用单一因素实验法和正交实验法,利用水冷系统和油气润滑系统实验平台,对不同转速下,不同工况对主轴轴承某点温升的影响进行实验分析。结果表明,冷却水流量为0.35m^3/h^0.38m^3/h,冷却水温度为17℃,空气压力为0.36MPa^0.39MPa,供油间隔为1min^2min时主轴温升最小。

Temperature rise is an important indicator of the working performance of the motorized spind-le.In order to study the effects of different parameters of water cooling system and oil and gas lubrication system on the temperature rise of high speed motorized spindle,and to find the optimal working conditions of the system. By the Single factor experiment and the orthogonal experiment method, take advantage of the watercooling system and the oil-lubrication system experimental platform,at different speeds, to analyze the affect on the temperature rise of spindle bearing under different cooling water flow rate,c-ooling water temperature,a ir pressure and oil supply interval. The experiment results shown that the temperature rise was minimal when the cooling water flow rate was 0. 35m^3 /h ~ 0. 38m^3 /h, the cooling water te-mperature was 17℃, the air pressure was 0. 36 MPa ~ 0. 39 MPa, the oil supply intervals was 1 min ~ 2 min.
