Use and maintenance of universal coupling

Use and maintenance of universal coupling

1, universal coupling before installation, should clean the two end, check the end keyway and other conditions, but tighten the screw, do not allow loosening;

2, after the universal coupling is installed, the normal operation of a class, must check all fastening screws, if found loose, must be tightened again with the specified tightening torque, so repeated several classes, to ensure that it will not loose;

3, in the operation of the work, should often observe whether the universal coupling abnormal radial swing and bearing heating phenomenon, found these phenomena must be timely maintenance;

4, in order to prolong the service life of the universal coupling, in the maintenance of disassembly and washing, the cross shaft is turned 180°, in order to achieve the shaft journal force alternate use;

5, universal couplings shall ensure that such as sliding surface, crosshead, bearing lubrication, usually with 2 # industrial lithium base grease or 2 # molybdenum disulfide calcium base grease, under the condition of the general gas with a continuous run of 500 hours, operating two months come on time, if under the condition of high temperature work must go once a week, come on when the screw hole of the bearing face oil, Injection with high pressure oil gun until overflow;

Universal coupling is mainly used for rolling machinery, lifting and transporting machinery and other heavy machinery, connecting two different axes of the drive shaft system. SWP type rotary diameter is 160-640mm, nominal torque is 16-1250kN. M, axis folding Angle A-F type ≤10°, G type ≤5°; SWC type rotary diameter is 100-620mm, nominal torque is 1.25-1000kn.m, axis folding Angle is 15°-25°.
