Introduction

  • The gears are a type of mechanical element whose teeth are cut around a cylindrical or conical surface with the same space.

​

  • It is used for the rotation and transmission of force from the drive shaft to the driven shaft when coupling a pair of elements.

​

  • The gears can be classified into
  • Spiral Gear
  • Cycloid and Tro-choidal Gears

Helical Gear

  • The helical gears are cylindrical gears that are used with parallel shafts similar to the spur gears and have winding teeth.

​

  • They have a better teeth grip than spur gears, have excellent low noise and can carry higher loads, which makes them suitable for high speed applications.
