What is Coupling? | Types of coupling in Hindi | Shaft Coupling, Rigid Couplings Flexible Couplings

Couplings are used to connect two shafts together in order to transmit power from driving side to the driven side while absorbing the mounting error (misalignment) etc. of two shafts.It is elaborates as under

A shaft coupling is a mechanical device used to connect two shafts together at their ends for the purpose of transmitting power. It allows for the transmission of torque from one shaft to another while accommodating misalignment, axial movement, or both. Shaft couplings come in various types, including:

Rigid Couplings
Provide a solid connection between shafts without any flexibility. They are used when shafts are perfectly aligned.

Flexible Couplings
Allow for some degree of misalignment or movement between shafts while transmitting torque. Examples include elastomeric couplings, gear couplings, and grid couplings.

Universal Joints
Also known as U-joints, they are used to transmit power between shafts that are not in a straight line or are at an angle to each other.

Oldham Couplings
Consist of three disks, with the middle disk being connected to one shaft and the outer disks being connected to the other shaft. They allow for axial movement and misalignment.

Disc Couplings
Use thin metal discs to transmit torque and accommodate misalignment. They are commonly used in high-speed and high-torque applications.

The choice of shaft coupling depends on factors such as the amount of misalignment, shaft speeds, torque requirements, and environmental conditions
