The bearing capacity of the tooth surface should be related to the hardness of the tooth surface. The higher the hardness, the higher the bearing capacity. According to the hardness of the tooth surface, people usually divide the gear transmission into two types, namely hard tooth surface gear transmission and soft tooth surface gear transmission. Usually, the tooth surface hardness of a pair of meshing gears is greater than 350HBW, which is called a hard tooth surface gear, otherwise it is called a soft tooth surface gear.
