1, cement Mill 2 base on the processing of bearing surface at the same horizontal plane, the center distance tolerance 1mm, not parallel to the longitudinal centerline degree of deviation 0.5mm, horizontal centerline deviation per meter 0.5mm.
2, tile seat angle spherical contact surface should be then evenly; each50mm2 of not less than 1-2 points; hollow shaft contact with the tile surface should be 90 ° -100 ° per square inch less than 2 points, journal and bearing two nearly the same side of space.
3, cement mill cylinder flange and the front cover of the mating surface should ensure good contact, are not allowed to add gaskets, two different hollow shaft axis degree of tolerance is less than 0.8mm. Large ring gear connected with the cylinder end cap assembly correction should be strong thrust, Shang Hao pin, ring gear of the radial oscillation is not more than 0.5mm, the axial oscillation is not more than 0.84mm.
4, cement mill liner installation should be press fitted cover, cylinder liner from Population Division, beginning with the assembly requirements, the screws should be uniform to tight and not leaking. Rubber liner with the prohibited gap, there are gaps Department to use sponge blocked.
5, the cement Mill pinion gear centerline and parallel to the centerline of its deviation per meter is not greater than 0.2mm. Tip clearance 1 / 4 module, tooth side gap 1.06 ----- 1.8mm, cement mill tooth surface contact area of not less than 50% of tooth length, tooth-high 40%
cement mill main wear scrapping Standard:
1, cement Mill bearing wear and tear is greater than the thickness of 1 / 3. String 7
2, cement Mill the small gear face wear should not be greater than the tooth thickness of 30%, large ring gear tooth surface wear greater than 25% of tooth thickness can be used face down, grinding to 1 / 2 should be scrapped.
3, cement Mill ring gear flange distortion degree of deformation should be greater than 7.5mm.
4, cement Mill outer surface of hollow shaft grooves, scarred or his inner circle of local Mochuan surface caused by hollow shaft deformation, cracks, etc. should be replaced.
