上海柴油机厂应用自制的空气轴承风动磨头对喷油嘴针阀体密封锥面进行加工。空气轴承就是利用空气作为润滑剂,在转动轴和轴承之间,产生一层气膜层代替一般滑动轴承所形成的油膜层,使主轴和轴承间被气所隔开。由于空气的粘度较油液低,减少了 Shanghai Diesel Engine Works made of air bearing air grinder nozzle needle valve body sealing cone processing. Air bearing is the use of air as a lubricant, between the rotating shaft and bearings, resulting in a layer of film instead of the general film formed by the sliding bearings, so that the spindle and bearings are separated by gas. As the air viscosity lower than the oil, reduced
