Topics in Shaft Couplings

1

Introduction to Shaft Couplings

  • Shaft couplings join two shafts to transmit rotary motion and power
  • Used when shafts are at distance or when connecting different machines
  • Shafts have limited lengths for transport ease, requiring connections
2

Types of Flange Couplings

  • Two main types: Unprotected and Protected flange couplings
  • Both use similar components but differ in flange shape
  • Protected type has additional safety features
3

Unprotected Flange Coupling - Design and Features

  • Two similar cast iron flanges with keyways in hubs
  • Rectangular sunk keys connect shafts to flanges at right angles
  • Keys driven from inside faces of flanges for easy fitting
4

Protected Flange Coupling - Design and Features

  • Similar components to unprotected type with modified flange shape
  • Flared and flattened rim (shroud) covers bolt heads and nuts
  • Enhanced safety prevents accidents and clothing entanglement
