The reasons why the elastic washer of the coupling is easily damaged are as follows:
1) The shaft system of the main engine and the pump and fan are not aligned, and additional torque is generated,
2) The quality of rubber components,
3) Torque matching problem, the rated allowable torque of the elastic coupling is too small,
4) The machining accuracy of the elastic ring hole is too low, or the hole is worn out,
All in all, the reason is complicated, and the specific situation needs to be analyzed in detail.
