Background

The gear has a wide application range, and is an important part in various mechanical equipment, such as machine tools, airplanes, ships, watches, electric fans and the like used in daily life. There are various kinds of gears, including a spur gear, a helical gear, a spur bevel gear, a helical bevel gear, and a worm gear. Among them, the spur gears are more used and are simpler, also called as standard spur gears. The parameters relating to the formation of the involute of the gear, the module, the pressure angle, etc. will be described in the course of the description. The processing method of the spur gear is mainly described, and the processing method of the gear tooth form has two types. One is a forming method, that is, a method of cutting out tooth form by using a forming milling cutter completely conforming to the shape of the tooth socket of the gear to be cut, such as milling tooth; the other is a generating method, which is a machining method for cutting out tooth shapes by using the intermeshing motion of a gear cutter and a driven gear, such as hobbing and slotting (exemplified by hobbing and slotting). The method of machining a gear with a milling machine is described below. Gears are toothed mechanical parts that can mesh with one another and are used in a very wide variety of mechanical transmission and overall mechanical applications.

The use of gears in transmissions has long emerged. In more than three hundred years before the first yuan, the problem of transferring rotary motion by bronze or cast iron gears was explained in "mechanical problem" by ancient greek philosopher, asia, swindle. The compass vehicle invented by ancient China has applied a whole set of wheel train.

Since gears are used in combination with gears to cause vibration and noise due to gear meshing caused by transmission errors, tooth collision caused by backlash, and the like, it is required to have higher fatigue strength, high abrasion resistance, high heat resistance, and high impact resistance than those of conventional gears, and further, to have characteristics such as high oil resistance, high gasoline resistance, and low impact resistance to gears of the meshing side.
