Gear refers to the gear on the rim of the continuous meshing transmission of movement and power of the mechanical components, by the gear tooth, tooth groove, end face, normal face, tooth top circle, tooth root circle, base circle, dividing circle and other parts, it is widely used in mechanical transmission and the whole mechanical field.

The role of the gear is mainly to transmit power, it can transfer the rotation of a shaft to another shaft, different gear combination can play a different role, can realize the mechanical deceleration, growth, change direction and reversing action, basically mechanical devices are inseparable from the gear.

There are many kinds of gears. According to the classification of gear shaft, it can be divided into three types: parallel shaft gear, intersecting shaft gear and staggered shaft gear. Among them, parallel shaft gear also includes spur gear, helical gear, internal gear, rack and helical rack, etc.Intersecting shaft gears have straight bevel gears, arc bevel gears, zero bevel gears, etc.The staggered shaft gear has staggered shaft helical gear, worm gear, hypoid gear and so on.

The steels commonly used in the manufacture of gears are tempered and tempered steels, hardened steels, carburized and hardened steels and nitriding steels.Cast steel has slightly lower strength than wrought steel and is often used for larger gear sizes.Gray cast iron has poor mechanical properties and can be used in light load open gear transmission.Ductile iron can partially replace steel to make gears.Plastic gear is mostly used for light load and low noise requirements, and its matching gear generally with good thermal conductivity steel gear.

In the future, the gear is developing in the direction of heavy duty, high speed, high precision and high efficiency, and strives for small size, light weight, long life and economic reliability.
