■ Simple and convenient assembly and disassembly;
■ No keyway and thrust ring are required on the shaft;
■ The stress on the entire contact surface is relatively uniform, and the stress concentration is not obvious;
■ When the vibration load of the shaft system changes, the shaft will not be worn;
■ The position of the coupling on the shaft is easy to ensure, and the connection accuracy is high;
■ Can be used repeatedly, with high interchangeability.
