[0002] Under normal working conditions, after a long period of use, ordinary rubber couplings are prone to elastic fatigue damage of the rubber, the torsional vibration strength of the elastic body is reduced, and the torsional torque is reduced, which leads to the failure of the elastic body and cannot compensate for the shaft transmission. The misalignment error generated during the installation and operation of the mechanism; the drum-shaped gear coupling has the disadvantages of high process requirements, high vibration noise, poor economy and pollution of the surrounding environment; The load needs to be used in pairs during installation, the axial distance is long, the volume is huge, and the error of the transmission is large at the same time
[0003] Most of the coupling halves are connected by bolts and nuts. Special tools are required for installation and disassembly, which is time-consuming, labor-intensive, inefficient and economical.
