【正文】 nce cost is also high. Simultaneously the bearing clearance adjustment difficulty, the gap is oversized, the working accuracy reaches does not request。s structure before the original main axle, simultaneously enhances the spindle speed to n max=900r/min, made the obsolete equipment to enhance the rigidity and the rotation precision, raised equipment39。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 the original main axle around as the datum adjusts, around definite main axle bearing hole proper alignment mon difference in the scope, before and, main bearing hole aperture processing to 。s method, carries on the lathe work, according to the bearing in the hole basic hole system39。19 ) the size 100 requests (request to leave leeway grinding allowance). Simultaneously processes the axis files adjustment thread separately again, in 1 adjusting nut and 2 adjusting blocks, the addendum circle adjusting shim (request filling piece thickness leaves leeway sharpening quantity). Finished, carried on the abrasive machining again to the main axle journal part, met the main axle proper each requirements.Figure 4 before the main axle, bearing meck part transformation3 assemblies and debuggingThe rotation stopping nut makes the end motion to the belt awl39。s radial clearance has adjusted suitably, otherwise the showing gap oversized or is too small, then screws tight the bolt 8. Rear bearing39。s regulation means are the same. In order to increase main axle39。 scope, achieves the reequipping the goal. After around the bearing assembly, the adjustment finished, carried on 1h the fast idling experiment, the main shaft bearing temperature does not surpass 70oC, then explained that around the main axle the bearing adjustment was suitable.4 r
