Finishing mill group 135m
The unit uses top cross 45 layout, reducing equipment center of gravity height,
increasing the stability of the unit, reducing the weight of the equipment, operation and maintenance more convenient as well.
Adjacent racks are arranged at 90 °to each other, achieving twist-free rolling.
Roll box with plug-in structure, cantilevered roll ring, cabinets equipped with eccentric mechanism for adjusting the roll gap. Eccentric sleeve is equipped with an oil film bearing and roller shaft, fixing roller ring with taper sleeve at the cantilever roller shaft end;
Bevel gearbox is composed of box, transmission shaft, spiral bevel gear pair. All gears are hardened grinding gear, axial modification, The accuracy level of spiral bevel gear is six, and cylindric spiral gear bevel is five to insure the smooth working of high speed.
Roll box and bevel gearbox are connected by bolts, a part of roller box body plug into the bevel gearbox to let roller shaft gear and two synchronized gears in bevel gearbox meshed. Roller box and bevel gearbox are fixed by two locating pin, the roller box with same specification can be exchanged.
Roller shaft at the roll side oil film bearing was designed tapered structure, so that, at the racks with a strong load, roll shaft can still get a uniform load distribution from the oil film bearing when the roll shaft bending. Thereby the lifetime of the roll shaft is increased.
The axial force of the roll shaft beared by a pair of thrust ball bearings, this ball bearing mounted on the no axial clearance resilient, because of the very small axial clearance of ball bearing itself, therefore, the roll shaft can accurately locate at the axial direction, which ensured the rolling precision of roll, meanwhile, ensured the dimensional accuracy of the rolled piece.
Roll gap adjustment is by rotating screw rod which having left and right screw thread and nut, so that two eccentric relative rotation, the spacing between the roll shafts changes roll gap with the eccentric relative rolling line symmetry movement of eccentric sleeve, and maintain the existing rolling line and guides position unchanged.
Collars are tungsten carbide, connected on the cantilever roll shaft by taper sleeve, we replace the collars by special hydraulic roll change tools, which are more convenient and easy.
