May 02, 2018

Generally there are teeth, cogs, end faces, French faces, tooth top circles, Chi Genyuan, base circles and indexing circles.

Gear tooth

In short, the tooth is a protruding part of the gear for meshing. The convex parts are generally arranged radially, and the teeth on the paired gears contact each other so that the gear can continue to engage and operate.

Alveolus

It is the space between the two adjacent teeth on the gear; the end face is the plane perpendicular to the axis of the gear or worm gear on the cylindrical gear or the cylindrical worm.

end face

It is the plane of the gear at both ends of the gear.

Normal face

It refers to the plane perpendicular to the tooth line of the tooth.

Tooth top circle

It refers to the circle at the top of the tooth.

Root circle

It refers to the circle in which the bottom of the groove is located.

Base circle

The forming line of the involute is formed as a pure rolling circle.

Indexing circle

It is the reference circle for calculating the geometric size of gears in the end face.
