A coupling is a component used to make connections between two components named shafts held together at their terminals for the purpose of power transmission. The absolute purpose of couplings is to connect two devices by rotating components. Simultaneously allowing some degree of misalignment or end pace
Typical Applications
Shaft couplings are used in machinery for several purposes. A primary function is to transfer power from one end to another end (ex: motor transfers power to a pump through a coupling). Other common uses:
Shaft couplings are employed in machinery for various jobs. A fundamental function is to transmit the power of one terminal to another, such as motor transmission power to a pump via coupling. Several more common uses are:
- To change the vibration benefits of rotating units
- To link the driving and the driven part
- To introduce the secure system
- To mitigate the transfer of shock loads from one shaft to another
- To slip when overload happens
Popular Coupling Types
A beam coupling, also called a helical coupling, is an adjustable coupling for the transmission of torque between two shafts, at the same time ensuring angular misalignment, continuous offset, and even axial rotation of one shaft relative to the other. In this design, a single piece of material is used, and it is made flexible by removing material along a spiral path to create a flexible beam that is bent and shaped like a helical spiral. The beam-type coupling does not display the backlash present in certain multi-piece couplings since it is manufactured from a single piece of material, including:
- Bush pin flange coupling
- Constant velocity coupling
- A clamp or split-muff coupling
- Diaphragm coupling
- Disc coupling
What are Couplings Used for?
Coupling is mechanical equipment used to link two straight line shafts to make sure one shaft drives the other at the same time and speed. A coupling can either be rigid or flexible, ensuring a large number of angular, radial and axial misalignments between the two shafts.
What is a Coupling Joint?
In the mechanical field, the coupling is defined as "a portion that joins two shafts together" and is sometimes referred to as a "coupling," "shaft coupling," or "joint." As demonstrated in the accompanying pictures, power may be transferred using a coupling even across axes of differing diameters. What a coupling does (shaft fitting)
