Gear Structure

May 06, 2020


Teeth for short, is a gear for each part of the projection for meshing, these projections are generally arranged in a radial form, matching the teeth on the gear contact each other, can make the gear continuous meshing operation.

The cogging

Is the space between two adjacent 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's the plane of the gear.

Method of surface

Refers to the plane perpendicular to the tooth line of the wheel.

Addendum circle

The circle at the top of the tooth.

Dedendum circle

The circle at the bottom of the groove.

Base circle

The generating line of an involute is a circle of pure rolling.

Dividing the circle

It is the reference circle to calculate the geometric dimension of the gear in the end face.
