The bearing capacity of the tooth surface should be related to the hardness of the tooth surface.
The higher the hardness, the higher the load carrying 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, called the hardened gear.
Otherwise it is called a soft toothed gear.
In the wind power-increasing gearbox, the input bearing is subjected to the force, torque and subversive moment of the common material of the shaft transmitted from the blade.
The gear on the intermediate shaft receives the torque transmitted from the input end and the braking torque transmitted from the output end brake.
The gear on the output shaft receives the torque transmitted from the intermediate shaft and also withstands the braking torque generated when the output brakes.
Generally there are gear teeth, cogging, end face, normal surface, tooth top circle, tooth root circle, base circle, and index circle.
Referred to as the tooth, is the convex part of each gear used for meshing.
These raised portions are generally arranged in a radial pattern.
The teeth on the mating gears are in contact with each other, so that the gears can continue to mesh;
It is the space between two adjacent teeth on the gear;
The end face is a spur gear or a cylindrical worm, perpendicular to the plane of the gear or worm axis.
Refers to the plane perpendicular to the tooth line of the tooth.
Tooth top circle
It refers to the circle where the tip of the tooth is located.
It refers to the circle where the bottom of the groove is located.
The line that forms the involute is a purely rolling circle.
It is the reference circle for calculating the geometry of the gear in the end face.
