What is a Gear Drive ? 

Gear drives find a very prominent place in mechanical power transmission. Gear drives are preferred when considerable power has to be transmitted over a short center distance positively with a constant velocity ratio.

Advantages of Gear drive

  1. It transmits exact velocity ratio
  2. It is used to transmit large power
  3. It has high efficiency
  4. It has reliable service and compact layout

Disadvantages of gear drive

  1. The manufacturing of gear requires special tools and equipment’s.
  2. The error in cutting teeth may cause vibrations and noise during operations.
