What are the different types of crankshaft? Explain each type of crankshaft

Welded crankshaft

  • In this type, each forging is made up of webs with crank pins and half of main journal on both sides.
  • Based on the units, number of such forgings are made.
  • These forgings were then welded together using a submerged arc welding process and stress relieved then machined to form the crankshaft.
  • These have the advantage of continuous grain flow, the webs could be made thinner, leading to a lighter shorter crankshaft.
  • Due to high Capital costs, only a few crankshafts of this type were made and used successfully.
