Teeth, referred to as teeth, are each of the gear for mesh of the raised part, these raised parts are generally arranged in a radial shape, the gear teeth on the pair of gear contact each other, can keep the gear engaged operation.
Is the space between two adjacent gear teeth on the gear;The end face is the plane of a cylindrical gear or worm perpendicular to the axis of the gear or worm.
It's the plane at both ends of the gear.
Method of surface
Refers to the plane perpendicular to the tooth line.
The circle where the top of the tooth is.
It's the circle where the bottom of the trough is.
The generating line that forms an involute is a pure rolling circle.
Dividing the circle
It is the reference circle for calculating the geometric dimensions of the gear in the end face.
