Explanation:

Helical Gear: 

  • In a helical gear, the teeth are cut at an angle to the axis of rotation.
  • It is used to transmit power between two parallel shafts. 
  • The end thrust is exerted by the driving and driven gears in the case of helical gears and the thrust may be eliminated by using double helical gears. These gears are called herring-bone gears.
