Bevel gears are used to transmit motion and power between two intersecting shafts. Bevel gears have indexing cones, tooth tip cones, tooth root cones, and base cones.

A cone has a large end and a small end, and the circles corresponding to the large end are called the indexing circle (with a radius of r), the tooth tip circle, the tooth root circle, and the base circle, respectively.

Application：

Bevel gears have important applications in construction equipment, automotive transmission systems, helicopter transmission systems, marine propellers, locomotives, and other fields
