Standard couplings model specifications and dimensions

Coupling is also called coupling. A mechanical component that securely connects the driving and driven shafts of different mechanisms to rotate together and transfer motion and torque. Sometimes it is also used to join the shaft with other parts (such as gears, belt wheels, etc.).

Couplings can be divided into two categories: rigid couplings and flexible couplings.

Rigid coupling does not have buffering and the ability to compensate the relative displacement of the two axes, the two axes are required to be strictly aligned, but this kind of coupling has simple structure, low manufacturing cost, assembly and disassembly. , easy to maintain, can ensure that the two axes have a high neutral, the transfer torque is large, widely used. Flange coupling, sleeve coupling and clamp shell coupling are commonly used.

Flexible coupling can be divided into elastic element flexible coupling and elastic element flexible coupling, the former only has the ability to compensate the relative displacement of two axes, but can not buffer vibration reduction, common slider coupling, tooth coupling, universal coupling and chain coupling, etc.; The latter category contains elastic elements, in addition to the ability to compensate the relative displacement of the two axes, but also has a buffer and damping, but the transmitted torque is limited by the strength of elastic elements, generally less than the elastic element flexible coupling, Common elastic sleeve pin coupling, elastic pin coupling, plum coupling, wheel coupling, snake spring coupling and reed coupling, etc.
