Use and maintenance of universal coupling

universalCouplingUse and maintenance
1. UniversalCouplingBefore installation, both ends should be cleaned, and the fit of the key grooves on the end face should be checked, and the screws should be tightened so that they are not allowed to loosen;
2. After the universal coupling is installed, run a shift normally. All the fastening screws must be checked. If they are found to be loose, they must be tightened again with the specified tightening torque. Repeat this for several shifts to ensure that they will not loosen;
3. During work and operation, you should always observe whether the universal joint has abnormal radial swing and bearing heating. If these phenomena are found, they must be repaired in time;
4. In order to prolong the service life of the universal joint, during maintenance, disassembly and washing, the cross shaft is rotated 180° to achieve alternate use of the journal force;
5. The sliding surface, crosshead, bearing, etc. of the universal coupling must be lubricated. Generally, 2# industrial lithium-based grease or 2# molybdenum disulfide calcium-based grease is used. Under normal conditions, it can be operated continuously for 500 hours and refueled once, intermittently. Refuel once every 2 months. If working under high temperature conditions, refuel once a week. When refueling, unscrew the oil hole screws on the bearing end surface and inject it with a high-pressure oil gun until it overflows;
万向联轴器主要适用于轧制机械、起重运输机械以及其它重型机械，联接两个不同轴线的传动轴系。SWP型回转直径为160-640mm，公称转矩为16-1250KN.m，轴线折角A-F型≤10°，G型≤5°；SWC型回转直径为100-620mm，公称转矩为1.25-1000KN.m，轴线折角为15°-25°。
