A compression coupling is defined as which type of coupling?

A compression coupling is classified as a rigid coupling because it is designed to connect two shafts in a manner that does not allow for any angular misalignment or axial movement. Rigid couplings create a solid and direct connection between the shafts, ensuring that torque is transmitted effectively without flexibility.

In the case of a compression coupling, it typically consists of a circular sleeve that compresses around the shafts when tightened. This compression fits the shafts snugly together, providing a strong and efficient connection. The primary function of a compression coupling is to maintain alignment and transmit torque without permitting any movement, which is a characteristic of rigid couplings.

Understanding the nature of rigid couplings is essential, as they are commonly used in applications where precision is vital, and any misalignment could lead to performance issues or mechanical failures.
