1, the two bearing base processing surface of the ball mill in the same horizontal plane, the center spacing tolerances 1mm, not parallel to the longitudinal centerline deviation 0.5mm rampant centerline deviation per meter 0.5mm. 2, the ball mill watts Block spherical contact surface should then angle uniform; 50 ⅹ 50mm2 within less than 1-2 points; should the hollow shaft watts contact surface 90 ah? 00 remorseful Division pepper then ⒋ the chi spring watch and? Point, journal and bearings on both sides of the gap is approximately the same. 3 cylinder flange and the mating surface of the front end cap should ensure good contact, and are not allowed to add pads, two hollow shaft misalignment tolerance of less than 0.8mm. Large ring and cylinder end cap connection assembly correction, the thrust should be strong, a good positioning pin, the ring gear of the radial wobble is not greater than 0.5 mm, axial runout is greater than 0.84mm. 4, the liner should be installed to install the end cap, cylinder liner should be at the entrance, assembly requirements, tighten the screws should be uniform, not leaking. Rubber liner with no gap, the crevice to use sponge blocked. 5, the centerline of the pinion gear center line with the large gear to be parallel, the deviation is not greater than 0.2mm per meter.
