Cross-shaft universal coupling is mainly applied to rolling machinery, lifting transport machinery and other heavy machinery. Universal coupling in the formal installation, be sure to first clean the two sides, check the end of the key slot with the situation, and then tighten the screws, do not loose. In the early use of the process, the normal operation of a class, you must check all the screws, if found to have some loose phenomenon, must be tightened again, so repeated several times, after the guarantee will not appear again loose phenomenon.

    In the course of the work, the need to constantly observe the universal coupling is abnormal bearing heat and the phenomenon of radial swing, etc., if these phenomena must be timely maintenance. Proper safety precautions must be applied to various places where personal and equipment accidents may result from the operation of the universal coupling in order to avoid such accidents.

    Universal coupling cross head, sliding surface, bearings, etc. must ensure adequate lubrication, in general, with 2 # industrial lithium-based grease or 2 # molybdenum disulfide calcium-based grease, if the work under high temperature conditions must be a weekly , In the usual continuous operation 500 hours refueling once, intermittent operation 2 months refueling time, refueling the bearing end of the oil hole screwed down, with high pressure oil gun into the overflow so far.

    Universal coupling, such as the discovery of indentation and other normal wear and tear phenomenon, should be replaced in time, the general use of 3 months will be maintained once. In order to extend the service life of universal coupling, in the maintenance of anti-washing into the cross shaft will be rotated 180 °, to achieve the use of journal force alternately; should avoid long-term overload and operation of the accident occurred.
