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.

The cogging

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.

End face

It's the plane at both ends of the gear.

Method of surface

Refers to the plane perpendicular to the tooth line.

Addendum circle

The circle where the top of the tooth is.

Dedendum circle

It's the circle where the bottom of the trough is.

Base circle

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.
