Speaking of gears, everyone is no stranger to it, so do you understand its function and structure?Let's take a look together below, the specific introduction is as follows:

Gears are important transmission parts that make up the machine.Its main function is to connect with shaft parts through flat keys or splines to form a whole.It meshes with another gear or gears.Transfer power and motion from one shaft to another.

The gear is a rotating part, and its structural feature is that the diameter is usually greater than the length.It is usually composed of outer cylindrical surface (conical surface), inner hole, keyway (spline groove), gear teeth, tooth groove and stepped end surface, etc., depending on the structure.Gears often have structures such as rims, hubs, webs, orifices, and spokes.

According to different structures, gears can be divided into solid type, web type, orifice type, spoke type and other types. If the gear and the shaft are made together, it will form a gear shaft.According to the different tooth profile and distribution form, there are many types of gears. Commonly used standard gears can be divided into spur gears.Helical cylindrical gears, bevel gears, etc.

All surfaces of the gear are ground. The roughness is less than Ra0.8.Surface treatment can be nitriding, carburizing, high-frequency quenching, carbonitriding and other processes.
