About gears 
1. Spur Gear
Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. 

2. Helical Gear
Helical gears are similar to spur gears except that their teeth are cut at an angle to the hole (axis) rather than straight and parallel to the hole like the teeth of a spur gear.

3. Worm Gear
The worm gear consists of a screw-shaped cut on the shaft (worm) and the mating gear (worm wheel). This gear type transmits the power in non-intersecting shafts that make right angles. 

4. Herringbone Gear
This set of quite similar to the double helical gear. However, they are smaller and have no space between the two helical faces. Herringbone gears have two helical gears joined side to side. 

5. Hypoid Gear
Hypoid gears appear similar to spiral bevel gears, but they function in non-intersecting shafts. They operate at 90 degrees and are common in automobile sectors. 

6. Internal Gear
An internal gear is a gear with teeth cut into the inside of a cylinder or cone. They are also known as ring gears or annuli. 

7. Planetary Gear
An epicyclic gear train is a gear reduction assembly consisting of two gears mounted so that the center of one gear revolves around the center of the other.
