【正文】 。s use factor.2 transformation process in does not affect the main axle other shafting ponents structure under the premise to open the original front bearing, and carries on the remanufacture processing to the original front bearing hole and the main axle. Like Figure 1, shown in Figure 2, and designs the axis front bearing which manufacture as shown in Figure 3. Its structure by the main axle, the end cover, the clamp, the shell, the bearing, the adjusting washer, the bolt, the stopping nut and so on is posed. This structure selected the D3182120 double row centripetal cylindrical roller bearing to transform the C620 lathe main axle front bearing structure, its principal advantage was: The rigidity is good, the rotational speed is high, and revolves steadily, the rotation precision is high, the radial direction beat is small, the thermostability is good as well as assembly technology capability good and so on characteristics. Just before the transformation, must inspect the headstock, the main axle hole size whether can transform. main axle holeFigure 1 after transformation front bearing holeFigure 2 after transformation main axleFigure 3 after transformation main axle front bearing1 main axle 2 end cover 4 shell 6, 9. stopping nutMeets the bearing outer diameter D=150mm size requirement, and inspects the main axle axle diameter whether can transform bearing inside diameter d=100mm the size, when the two meet the above requirement, then begins to arrange the transformation work. headstock main axle front bearing hole transformationIn order to guarantee lathe main axle hole and rolling bearing outer ring39。s grade of fit, when processing should follow the basic shaft system the principle, and arranges on the clang bed to carry on the clang hole processing to the headstock front bearing hole. This work must be very careful, achieves the craft precision for the guarantee, truncates when the processing must the bearing hole carry on take
