The term “shaft coupling” is common in the engineering world, it is known as a part that connects two shafts together in order to accurately transmit power. The transmission is done from the drive side to the driven side while absorbing the mounting error (misalignment), etc. of the two shafts. Coupling is used in almost all industrial machines that require power transmissions, such as motors, pumps, generators, and compressors.
Applications of shaft coupling
Just as earlier mentioned, shaft couplings are used in almost all industrial machinery for several purposes. The primary function is for power transfer from one end to another end. For example, a motor transferring power to a pump through coupling. Below are the general applications of coupling.
To transmit power from the driving shaft to the driven shaft.
Couplings connect or couple two components that are separately manufactured, i.e., output motor shaft and generator.
It reduces the transmission of shock loads from one shaft to another by using flexible couplings.
Couplings are also used to introduce extra flexibility while transmitting power in case of space restrictions.
To introduce protection against overloads.
Requirements of a good shaft coupling
Below are the requirements to consider to know a good coupling system.
Coupling should be able to transmit torque from driven shaft to driven shaft.
It should align the shafts properly.
Couplings should provide safety to man and machine in case of coupling failure.
Couplings should be able to dismantle for the purpose of maintenance.
Finally, couplings should be adjustable.
