Explanation:

The couplings are used to:

  • Connect two shafts together, in order to transfer rotary motion from one to another.
  • provides slip-free drive
  • compensate for slight misalignment between the two shafts and provide for axial movement along their axis.

Types of coupling:

Plate coupling: When shaft ends can be brought into perfect alignment, such shafts can be coupled together by means of a plate coupling. The shaft cannot be shifted in the axial direction.

Clamp coupling: This coupling is built up of two parts which are placed over the connecting ends of the shafts. The clamp coupling joins two shafts when they are in alignment, and this coupling does not permit any movement of the shafts. It is also known as Split muff coupling. It is used in textile industries.

Flange coupling is a driving coupling between rotating shafts that consists of flanges (or half couplings) one of which is fixed at the end of each shaft, the two flanges being bolted together with a ring of bolts and nuts to complete the drive.
