Use and maintenance of coupling

　　When choosing a standard coupling, the drum-shaped gear coupling should be based on the use requirements and working conditions, such as carrying capacity, speed, relative displacement of the two shafts, buffering and vibration absorption, as well as assembly and disassembly, maintenance and replacement of the vulnerable drum-shaped gear coupling Wait for comprehensive analysis to determine.
　　Assembly technology and maintenance of the coupling:
　　1) When assembling, remove burrs and clean all parts
　　2) When assembling, it is necessary to ensure that the center lines of the two welded fork bearing holes in the middle are on the same plane, and the allowable difference should not exceed 1°, the spline part should slide freely, and the joints should rotate flexibly
　　3) Clean the surface, except for the flange end face and the end face key with anti-rust grease, brush the anti-rust primer once and then spray paint (no paint).
　　4) Regular lubrication, it is recommended to inject oil once a week, and once a day under high temperature conditions.
　　5) In order to increase the service life of the universal coupling, adjust the cross shaft by 180 degrees each time it is disassembled so that the cross shaft journals can be used alternately
