When there’s a gear problem everything can come to stop because of this it’s important for you to understand how gears work in order to keep them working in their associated equipment operating

Gear can be defined as a toothed wheel that can be engaged in another toothed wheel in order to transmit energy that gives the change of speed and direction of motion. It is widely used in mechanical devices. The teeth of the gear are generally carved on wheels, cylinders, or cones.

Many devices that we use in our day-to-day life have their own working principle. The tooth and wheel of gear are working parts of all types of gears. The different types of gears are used to complete the transfer of energy in different ways and in different directions.

A gear is a component within a transmission device that transmits the rotational force to another gear or device. Gear is different from a pulley in that a gear is a round wheel that has teeth that mesh with other gear teeth. Allowing the force to be fully transferred without slippage.

Depending on their construction and arrangement, geared devices can transmit forces at different speeds, torques, or in a different direction, from the power source.

The most common situation is for a gear to mesh with another gear. To overcome the problem of slippage as in belt drives, gears are used which produce a positive drive with uniform angular velocity.

Classification of Gears

1. Parallel gears
   1. Spur Gears
   2. Helical Gears
   3. Double Helical or Herringbone Gears.
2. Perpendicular axis gears
   1. Nonintersection perpendicular axis
   2. Intersection perpendicular axis gear
3. Intersecting gears
   1. Spiral gears
   2. Bevel Gears
4. Non-intersecting and Non-Parallel gears.
   1. Worm Gears
5. Rack and Pinion gears

Gears or toothed wheels may be classified according to the axes of the two shafts between which the motion is transmitted. The types of gears are to be determined based on the application in which they are to be used.
