Generally, there are gear teeth, tooth grooves, end faces, normal faces, tooth crest circles, tooth root circles, base circles and index circles.
Gear teeth: Referred to as teeth, it is each convex part on the gear for meshing. These convex parts are generally arranged in a radial pattern. The gear teeth on the mating gears are in contact with each other to make the gears continue to mesh.
Teeth: It is the space between two adjacent gear teeth on the gear; the end face is the plane on the cylindrical gear or cylindrical worm perpendicular to the axis of the gear or worm.
End face: It is the plane at both ends of the gear.
Normal: refers to the plane perpendicular to the tooth line of the gear.
Tooth top circle: refers to the circle where the top of the tooth is located.
Root circle: refers to the circle where the groove bottom is located.
Base circle: a circle that forms an involute occurrence line for pure rolling.
Indexing circle: It is the reference circle for calculating the geometric dimensions of the gear in the end face.
