我厂加工高精度滑动轴承(图1)时,同轴度要求严格。我们采用先精车内孔、以内孔为定位基准精车外圆,并设计了液塑心轴,采用润滑脂代替液性塑料,免去了对环境的污染,润滑脂在常温下为半液体状态,传递压力均匀。但应注意选择润滑脂的滴点须高于工作温度10℃以上。 使用时用手转动螺套5(图2)、推动滑柱4使润 I plant processing high-precision plain bearings (Figure 1), the coaxial requirements of the strict. We use the first fine car inner hole, with the hole as the reference standard fine car outer circle, and the design of the liquid plastic mandrel, the use of grease instead of liquid plastic, eliminating the pollution of the environment, grease at room temperature for the semi-liquid State, transmit pressure evenly. However, it should be noted that the choice of grease dropping point must be higher than the working temperature above 10 ℃. Use hand to turn the screw sleeve 5 (Figure 2), pushing the spool 4 to run
