Make a mark on the positions of each part of the shaft assembly before the coupling is removed. For reference in installation. Remove the coupling, not directly with a hammer and copper pad, and should play at the coupling hub can't play coupling outer edge, it is easy to be broken because. Couplings, nuts, bolts, washers and so on must be guaranteed to their specifications, size consistent, so as not to affect the dynamic balance of the coupling. After assembly, all parts of the coupling are cleaned and cleaned. Use the oil to clean the parts. The cleaned parts will be dried by compressed air. If the couplings are ready for a short period of time, the drying parts shall be coated with some turbine oil or oil to prevent rust. For the need for longer time to use the coupling, should be coated with rust preventive maintenance. Qingdao Qingshan transmission shaft Co., Ltd. is engaged in couplings, universal couplings, couplings manufacturers, universal transmission shafts and universal joint couplings.
