What is another name for a flexible coupling?

**Flexible Coupling: A Versatile Connector**.

Flexible coupling, also known as a universal joint, is a mechanical device used to connect two shafts together at their ends for the purpose of transmitting power. It allows for a slight angular misalignment between the shafts while transferring torque from one to the other.

### Why is it called a flexible coupling?

One of the main benefits of a flexible coupling is its ability to compensate for misalignment between shafts, whether it be angular, parallel, or axial misalignment. This flexibility helps to reduce stress on the shafts and bearings, resulting in a smoother operation and longer life for the connected equipment.

### How does a flexible coupling work?

A flexible coupling typically consists of two hubs, each attached to a shaft, and a flexible element that connects the hubs. The flexible element, which can be made of materials such as rubber, metal, or plastic, is able to flex and twist, allowing for the misalignment between the shafts. As the shafts rotate, the flexible element deforms accordingly, transmitting torque from one shaft to the other.

### What are some common types of flexible couplings?

There are several types of flexible couplings available, each designed for specific applications and requirements. Some common types include:

1. **Jaw Coupling**: This type of coupling uses elastomeric spiders to provide flexibility and damping of vibrations.

2. **Gear Coupling**: Gear couplings use gear teeth to transmit torque and are ideal for high-speed and high-torque applications.

3. **Disc Coupling**: Disc couplings utilize thin metal discs to transmit torque and are known for their high torsional stiffness and misalignment capabilities.

4. **Beam Coupling**: Beam couplings are made of a single piece of material with spiral cuts to provide flexibility and compensate for misalignment.

### Conclusion.

In conclusion, a flexible coupling, also known as a universal joint, is a versatile connector that allows for misalignment between shafts while transmitting torque. Its ability to reduce stress and vibrations makes it a critical component in various mechanical systems. By understanding how flexible couplings work and the different types available, engineers and designers can select the most suitable coupling for their specific application.
