A shaft coupling is used to connect two shafts that turn in the same direction on the same centerline. The major types are rigid, flexible, and U-joints (universal joints). Rigid couplings are used to connect shafts that are precisely aligned. Flexible couplings, which make up 90% of couplings sold, are designed to transmit torque while permitting some radial, axial, and angular misalignment. They can accommodate angular misalignment up to a few degrees and some parallel misalignment. U-Joints are used to connect shafts that intersect at angles greater than what a flexible coupling can handle.

Functions of Shaft Couplings

  • Connect or extend the driving or driven shafts
  • Manage misalignment between shafts
  • Transmit rotary power from one shaft to another
  • Protect expensive equipment
  • No efficiency loss
  • Cushion shock loads
  • Electrically insulate drive
  • Limit end float
  • Provide a place for clutching components
  • Provide torsional tuning by varying stiffness
