shaft coupling

What are the three types of coupling?

Couplings are categorized into three primary types based on their function and design: rigid couplings, flexible couplings, and fluid couplings.

shaft coupling

What coupling is used to connect two shafts?

To connect two shafts, the type of coupling used depends on specific operational requirements:

  • Shaft Diameter Compatibility: The coupling must fit the diameter of the shafts being connected.
  • Torque Transmission: The coupling must be capable of transmitting the required torque without slipping.
  • Misalignment Accommodation: Some couplings can accommodate angular, parallel, or axial misalignments between shafts.
  • Environmental Conditions: The coupling material and design should be suitable for the working environment, whether it is corrosive, high-temperature, or otherwise challenging.
  • Speed of Operation: High-speed applications require couplings with specific balance and stiffness characteristics to prevent vibrations.

What are the two general types of shaft couplings?

Generally, shaft couplings are classified into two broad categories:

  • Rigid Couplings: These couplings are used when precise alignment is required and no relative motion between the shafts is anticipated. They are typically used in applications where shafts are aligned accurately.
  • Flexible Couplings: Flexible couplings can accommodate misalignments and provide some degree of flexibility between the connected shafts. They are used in applications where slight misalignments or movements are expected.
