What coupling is used to connect two shafts?

The selection of a coupling to connect two shafts depends on various parameters:

  • Torque Requirements: The coupling must handle the maximum torque transmitted between the shafts to ensure reliable performance.
  • Shaft Misalignment: Assessing angular, parallel, and axial misalignments is crucial to select a coupling that can compensate for these deviations.
  • Environmental Conditions:
  • Space Constraints: The physical space available for the coupling installation must be considered to select the appropriate size and type.
  • Operational Speed: The coupling must support the required rotational speed without causing excessive vibration or noise.

What are the two general types of shaft couplings?

The two general types of shaft couplings are rigid couplings and flexible couplings. Rigid couplings provide a solid connection with no allowance for misalignment, while flexible couplings can accommodate various types of misalignment and provide damping of vibrations.
