The gear can be divided into a cylindrical gear, a bevel gear, a non-circular gear, a rack and a worm and worm wheel according to the shape of the gear; according to the shape of the tooth trace, the gear is divided into a straight gear, a helical gear, a herringbone gear and a curve gear; the gear is divided into an external gear and an internal gear according to the surface where the gear teeth are located; they can be classified into cast gears, cut gears, rolled gears, sintered gears, etc. according to the manufacturing method. The material of manufacture and the heat treatment process of the gear have a great influence on the load-bearing capacity and the dimensional weight of the gear. Before the 50 s of the 20 th century, gears were made of carbon steel, alloy steel was used in the 60 s, and case-hardened steel was used in the 70 s. The tooth surface can be divided into a soft tooth surface and a hard tooth surface according to hardness. The soft tooth surface gear has low bearing capacity, but is easy to manufacture, has good running-in performance, and is mainly used in general machines with transmission size and weight without strict limitation and small-scale production. Because the load of the small gear is heavy in the paired gears, the hardness of the tooth surface of the small gear is generally higher than that of the large gear in order to make the service lives of the large gear and the small gear approximately equal. The bearing capacity of the gear with the hard tooth surface is high, and the gear is subjected to quenching, surface quenching or carburizing and quenching treatment after being subjected to fine cutting so as to improve the hardness. However, since the gear inevitably deforms during the heat treatment, grinding, lapping or finish cutting is required after the heat treatment to eliminate errors caused by the deformation and improve the accuracy of the gear.
