What are the disadvantages of muff coupling?

Muff coupling is also called sleeve coupling is the simplest type of rigid coupling that consists of a hollow cylinder. Whose inner diameter is the same as a shaft. It is fitted over the ends of two shafts by means of gif head key and power transmitted from one shaft to another by means of a key and a sleeve. Now, let us have a deep insight into the disadvantages of muff coupling in this article. 

Disadvantages of muff coupling:

  • Muff coupling is difficult to assemble or dismantle.
  • It is a rigid type of coupling and requires accurate alignment of shafts.
  • It can not absorb shocks and vibrations because there are no flexible parts.
  • This coupling is used where the motion is free from vibrations.
  • It requires more axial space compared with flange coupling.
