What coupling is used to connect two shafts?

When connecting two shafts, the choice of coupling depends on several parameters:

  • Torque Requirements: Determine the amount of torque to be transmitted to select a coupling that can handle the load.
  • Alignment: Assess the alignment of the shafts. Flexible couplings are suitable for misaligned shafts, while rigid couplings require precise alignment.
  • Operational Speed: Higher speeds may necessitate couplings with specific balancing and vibration damping characteristics.
  • Environmental Conditions: Consider the operating environment, including temperature, humidity, and exposure to chemicals, which may affect coupling material and design.
  • Space Constraints: Evaluate the available space for installation as different couplings have varying size requirements.

What are the two general types of shaft couplings?

There are two general types of shaft couplings: rigid and flexible. Rigid couplings provide a solid connection and are used where precise alignment is possible. Flexible couplings, on the other hand, accommodate misalignment and reduce vibration, making them suitable for a wider range of applications.
