How are couplings classified?

Taday, We introduce how are couplings classified?

1. Rigid coupling (no compensation capacity);
2. Flexible beam coupling (with compensation capability);
3. Flexible couplings for inelastic elements: These couplings are flexible and can compensate the relative displacement of two shafts.
   However, due to the inelastic element, it cannot buffer and reduce vibration.
   Such as: cross slider coupling, cross shaft gear coupling,universal coupling
4. Flexible couplings with elastic elements: These couplings are equipped with elastic elements, which can not only compensate for the relative displacement between the two shafts, but also have the capability of buffering and reducing vibration.

Extension materials:

A coupling is a mechanical part used to join two shafts of different mechanisms (the drive shaft and the driven shaft) to rotate together to transfer torque.
In high speed and heavy load power transmission, some couplings have the functions of buffering, damping and improving the dynamic performance of shafting.

The coupling consists of two halves connected with the driving shaft and the driven shaft respectively.
Most power machines are connected with working machines by means of couplings.

According to the size of the transferred load, the height of the shaft speed, the installation accuracy of the two parts connected, etc., referring to the characteristics of various couplings, choose a joint type of coupling.
The specific selection can consider the following points:

The torque and properties to be transferred and the requirements for the buffering and vibration reduction function.
For example, for high-power heavy-duty transmission, can choose the gear coupling;

For the transmission with severe impact load or the need to eliminate torsional vibration of shafting, high flexibility couplings such as tire couplings can be selected.

The working speed of the coupling and the magnitude of the centrifugal force.
For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be selected, and should not be selected with eccentric sliding coupling.
