What coupling is used to connect two shafts?

To connect two shafts, various couplings can be employed depending on the application requirements. Key parameters and conditions to consider include:

  • Torque Transmission: The coupling must be capable of transmitting the required torque without slippage or failure.
  • Misalignment Accommodation: The ability to accommodate angular, parallel, and axial misalignments between the shafts.
  • Vibration Damping: Some couplings are designed to reduce vibrations and noise, enhancing the overall performance of the machinery.
  • Material Compatibility: The materials of the coupling should be compatible with the operational environment to avoid corrosion or wear.
  • Ease of Maintenance: Consideration for easy installation, maintenance, and replacement to minimize downtime.
