Which of the following coupling working to joint two shafts with large angular misalignment?

Which of the following coupling working to joint two shafts with large angular misalignment? Correct Answer Universal coupling

Explanation:

Universal Coupling: 

The other name of universal coupling is hook coupling.

  • The simplest type of coupling allows a large angle between drive halves.
  • Each side of coupling includes protruding pins.
  • The halves of the coupling are fastened in a pivoting assembly.
  • At all angles, up to about 40° the pins interlock with each other, and rotation on one-half forces the other half to rotate.
  • Low power use only.
  • Not smooth.
  • Not reliable.
  • Really only suitable for remote manual operations.

Additional InformationRigid coupling​

  • This type of coupling requires the perfect alignment of the shafts to be joined.
  • The most widely used rigid coupling is –
    1. Box / Muff / Sleeve coupling
    2. Split Muff / Clamp coupling
    3. Cast iron flange coupling

Oldham Coupling:

  • This is used to join two laterally non-aligned shafts which are parallel.
  • It consists of two flanges with slots and a central floating part is held by means of a pin passing through the flanges.
