Get to Know All about Flexible Couplings

Little misalignment can be accommodated in Flexible couplings but as an excuse, it should not be used for poor alignment or no maintenance. On either the motor or the driven load misalignment of flexible coupling can lead to excessive force. This can even lead to the failure of other components or huge amounts of vibration.

The alignment of the motor and the load should be regularly checked even if flexible couplings are used.



Some transmitting power method is needed between the two machines rotating equipment using separate driving and driven machines. With universal joints or coupling of a particular design, this can be a drive shaft. They operate as a single shaft only when two shafts are properly connected by rigid coupling.

To general purpose couplings, special purpose couplings are quite similar. They are designed in a way so that they can perform the same functions as general-purpose couplings perform but at higher speeds and horsepower.

Between the shafts of the driver and driven machines, a rigid coupling does not permit relative motion. For vertical applications, e.g., vertical pumps a rigid coupling is primarily used. To connect two axially oriented shafts a flange flexible coupling is used. Transmitting torque or rotary motion without slip is its main objective and for angular, parallel, and axial misalignment, it compensates at the same time. They can also provide damping of vibration and tensional changes depending upon the design. To conveyors, drive pumps, compressors, motor-generator sets, fans, crushers, vibrating screens, etc. flexible couplings are often used.

With some lack of concern, it may be viewed as a flexible coupling joining two types of equipment. You will find many manufacturers available in the market providing good quality products. It can be a major contributor to the performance problems of the two machines.

Classification of Flexible Couplings

Based on the coupling falling into one or more of the following groups flexible couplings from flange flexible coupling manufacturer are often classified:

• Lubricated / non-lubricated (dry)

• Low speed / high speed

• Mechanical or metallic/elastomeric

• General-purpose / special purpose (high performance)
