Cross axis universal jointcouplingmainapplyConnect two transmission shafts with different axes for rolling machinery, lifting and transportation machinery, and other heavy machinery. The SWP type has a turning diameter of 160-640mm, a nominal torque of 16-1250KN. m, an axis angle of A-F type ≤ 10 °, and G type ≤ 5 °; The SWC type has a turning diameter of 100-620mm, a nominal torque of 1.25-1000KN. m, and an axis angle of 15 ° -25 °.
2、 WanxiangcouplingThe connection method
universalcouplingIt is to use high-strength bolts and self-locking nuts to connect the flanges at both ends to other mechanical components, and the torque is transmitted through the flange end face key and the friction force between the flanges. The connection dimensions and bolt pre tightening torque of SWP type shall be in accordance with the provisions of Figure 3 and Table 3; The connection dimensions and bolt pre tightening torque of SWC type shall be in accordance with the provisions of Figure 4 and Table 4.
Bolts can only be used from andcouplingThe matching flange side is inserted, and the nut is made of universal jointcouplingThe flange side of the bolt should be tightened, and the mechanical properties of the bolt should meet the requirements of level 10.9 in GB3098.1, while the mechanical properties of the nut should meet the requirements of level 10 in GB3098.4.
3、 WanxiangcouplingThe use and maintenance of
1. WanxiangcouplingBefore installation, both end faces should be cleaned, and the fit of the end face key slot and other components should be checked. The screws should be tightened and not allowed to loosen;
2. WanxiangcouplingAfter installation and normal operation for one shift, all fastening screws must be checked. If they are found to be loose, they must be tightened again with the specified tightening torque. Repeat this process for several shifts to ensure that they do not loosen;
3. WanxiangcouplingSliding surfaces, crossheads, bearings, etc. must be lubricated. Generally, 2 # industrial lithium based grease or 2 # molybdenum disulfide calcium based grease is used. Oil should be added once every 500 hours of continuous operation under normal conditions, and once every 2 months of intermittent operation. If working under high temperature conditions, oil must be added once a week. When adding oil, unscrew the oil hole screw on the bearing end face and inject it with a high-pressure oil gun until it overflows;
4. WanxiangcouplingGenerally, maintenance should be carried out once every 3 months. If normal wear and tear such as indentation is found, it should be replaced in a timely manner;
5. To extend WanxiangcouplingThe service life of the cross shaft should be adjusted 180 ° during maintenance, disassembly, and washing to achieve alternating use of the shaft neck under stress;
6. Long term overloading and operational accidents should be avoided;
7. During work operation, it is important to regularly observe the gimbalcouplingWhether there are abnormal radial oscillation and bearing heating phenomena, and if these phenomena are found, they must be repaired in a timely manner;
8. Due to the possibility of universal rotationcouplingAppropriate safety measures must be taken in all places that may cause personal and equipment accidents.
