What are the classifications of couplings

CouplingThe classification is as follows:
Rigid coupling: Rigid coupling does not have the ability to compensate for the relative deviation of the axis of the two coupled shafts, nor does it have shock absorption performance; but the structure is simple and the price is cheap.Rigid couplings can only be used when the load is stable, the speed is stable, and the relative deviation of the axis of the two shafts to be coupled is extremely small.

Flexible coupling: It has a certain ability to compensate for the relative offset of the two shafts being coupled, and the maximum number varies with different models.

Flexible coupling without elastic elements: large load-bearing capacity, but also does not have cushioning and shock absorption performance, and there will be impact noise at high speed or unstable rotation or frequent forward and reverse rotation.It is suitable for occasions with low speed , heavy load and stable speed.

The flexible coupling of non-metallic elastic elements has good cushioning and shock absorption performance when the speed is not stable; however, due to the low strength of non-metallic (rubber, nylon, etc.) elastic elements, short life, small load-bearing capacity, and high temperature resistance Low temperature, so it is suitable for high speed, light load and normal temperature occasions

Flexible coupling of metal elastic elements: In addition to having better cushioning and shock absorption performance, it has a large load-bearing capacity, and is suitable for large changes in speed and load and high or low temperature occasions.

*Coupling: The structural feature is that there is a safety link (such as a movable pin connection, etc.), which can only bear a limited load.When the actual load exceeds the previously limited load, the insurance link changes, cutting off the transmission of motion and power, so as to protect the rest of the machine from damage, that is, it plays a protective role.Starting* Coupling: In addition to the overload protection function, it also has the function of transforming the machine motor's on-load starting into an approximate no-load starting.
