What to Focus On

  • Couplings connect two shafts end-to-end for power transmission
  • Used to extend shaft length or connect different machines
  • Enable transmission of rotary motion and torque

  • Standard form of coupling extensively used in industry
  • Consists of two similar flanges mounted on respective shafts
  • Suitable for heavy loads and high power transmission

  • Basic form with exposed bolts and nuts on outer circumference
  • Two cast iron flanges with keyways in central hubs
  • Shafts secured with rectangular sunk keys at right angles

Common Mistakes to Avoid

All flange couplings are the same - protected and unprotected types are just different names for the same thing

Keys in both shafts of a flange coupling are aligned parallel to each other

Spigot and socket arrangement is just decorative and doesn't serve any functional purpose

Memory Tips

Definition of Shaft Coupling

Two types of Flange Couplings: Protected and Unprotected

Unprotected Flange Coupling has exposed bolt heads

Protected Flange Coupling has shrouded rim covering bolt heads
