Gear Drives

What is gear ?

Gears are toothed discs which is used to transmit motion between two shafts with minimal losses. Gears are positive drives.

Positive Drive : Positive drives are those which transmit motion without any slip.

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.
