Function:

It is used to transmit rotational motion between two axes.

Types:

Gears are classified in cylindrical, conical, hyperboloid and worm gears. They are identify by the form of their teeth as well.

Gears’s mechanism:

  1. Reducers/multipliers: They are used to decrease/increase driven shaft’s revolution per minute to driver shaft’s.
  2. Transmission gears: They permit to change driven shaft’s speed stepwise. It is possible connecting diferent sprocket chains.
  3. Setting mechanim: It allows you to set the required gear ratio and obtain the demand speed of driven shaft.
