Flexible Coupling

Definition

A Flexible Coupling is a mechanical connection that adapts to misalignment between moving parts.

Purpose

The purpose of a Flexible Coupling is to connect two rotating shafts or components while accommodating misalignment, reducing vibration, and absorbing shock, thereby extending the life of the connected machinery.

Examples of Use

• Machinery: Connecting motors and pumps in industrial equipment to accommodate misalignment and reduce wear.
• Automotive: Using flexible couplings in drive shafts to absorb shock and reduce vibration.
• HVAC Systems: Employing flexible couplings in fans and blowers to accommodate slight misalignments and reduce noise.

Related Terms

• Rigid Coupling: A coupling that does not accommodate misalignment between connected parts.
• Vibration Damping: The process of reducing or eliminating vibration in mechanical systems.
• Shaft: A rotating machine element that transmits torque and rotation.

Notes

• Selecting the appropriate flexible coupling type and size is essential for optimal performance and longevity.
• Regular inspection and maintenance of flexible couplings are necessary to ensure they continue to function correctly.
