Gear coupling is a common mechanical part used to transmit torque in gear reducer. It is composed of two parts, the driving shaft and the driven shaft.

Coupling refers to a device that connects two shafts or shafts and rotating parts to rotate together in the process of transmitting motion and power, and does not disengage under normal circumstances.

Taper sleeve is a new type of machine transmission connection part widely used in Europe and the United States, which has the characteristics of high scale level, high precision, compact layout, convenient installation and disassembly.

Couplings belong to the category of general mechanical parts. Common couplings include diaphragm couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings and serpentine spring couplings.
