摘　　要：针对T2120型深孔钻镗床在加工机床临界尺寸Ф30孔时遇到的输油器内部系统不稳定及头部"发热"问题,通过分析输油器所受切削液的压力及其轴承产生的热量,并用Deform模拟其轴承在外力作用下的温度场,得出输油器所出现的问题是由于切削液作用力过大引起的.通过对输油器内部结构的优化改进,降低了切削液作用面积,减小了切削液作用力,从而解决了系统不稳定及轴承摩擦引起的发热过高问题,也方便拆卸,不影响原有输油器的加工能力,增大了输油器的加工孔范围.Aiming at the Internal system of oil feeder instability and oil feeder head＂heating＂problems of the T2120-type deep-hole boring and boring machine in the processing critical size ofФ30holes,through the analysis of the cutting fluid pressure for oil feeder and the heat generated by the bearing,and using the Deform software to simulate the bearing temperature field under the action of external force,the oil feeder problem was due to excessive force caused by cutting fluid pressure.With the optimization of the internal structure of oil feeder,the cutting fluid function area and the cutting fluid force were reduced.Accordingly,the oil feeder internal system instability and high fever problem caused by bearing friction were solved,which also can be expediently dismountable,does not effect the processing capacity of the original oil feeder and expand the processing scope of the oil feeder.
