As per industry requirements, Couplings are considered as the most demanded mechanical device which is used to connect two shafts together at their end for the purpose of transmitting power. So, let’s learn what are its types and function is.
What Are The Types Of Couplings?
There are various types of couplings used in the industry today and the most common ones are the rigid and flexible couplings.
A rigid coupling is also used to hold two shafts, but since these are rigid, there are accurate allowance of alignment and a secured holding of the two shafts together, rigid couplings maximize the performance of the machine.
Flexible coupling also has the primary function of holding of two shafts together, however there is more flexibility of the shafts when there is any sort of misalignment occurs as compared to the rigid coupling.
Both have its own advantages depending upon their application.
What Are The Functions Of Couplings?
As above discussed, the primary function of couplings are not only to transmit power, but there are many functions which this coupling has, which are as follows,
- To connect two shafts of units together,
- To accommodate any misalignments of shafts, which is the benefit of the construction,
- To provide a mechanical flexibility for the proper functioning,
- To reduce any shock loads from one shaft to another, and
- To connect the driving and driven part.
What Is The Most Popular Coupling Used?
Gear Coupling is one such device that is widely used as it has the potential of longer longevity and flexibility and it is used for mechanical power transmission. It is popular as because it is highly durable and can be installed easily. The Gear Couplings are manufactured in two ways to accommodate its application easily, which are, Full Gear Coupling and Half Gear Coupling.
An engineer must know the work load to which a coupling will be exposed and one should choose a coupling based on its application and not on its price.
