What are the three types of coupling?

There are three primary types of coupling:

  • Rigid Couplings: These are used where precise alignment of shafts is required and no relative motion between the shafts is anticipated.
  • Flexible Couplings: These can accommodate some degree of misalignment and provide vibration damping, making them ideal for applications with varying load conditions.
  • Fluid Couplings: Utilizing hydraulic fluid for torque transmission, these couplings are used in applications where smooth power transmission is necessary, such as in automotive transmissions.
