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.
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.
It's the plane of the gear.
Method of surface
Refers to the plane perpendicular to the tooth line of the wheel.
The circle at the top of the tooth.
The circle at the bottom of the groove.
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.
