Bevel gears are bevel gears and bevel gears. Bevel gears are most commonly used for transmission of two vertical shafts, but they are also suitable for transmission of two shafts at other angles. The most typical application is to drive a vertical pump with a horizontal drive device. The two main differences between bevel gears and spur gears are their shape and their relationship to the axis on which they are located. The bevel gear is conical in shape, while the spur gear is originally a cylinder. The bevel gear transmits the movement between two angled shafts, that is, the cross shaft, while the spur gear transmits the movement between the two parallel shafts.

Bevel gears are processed on a special gear-shaping machine. Bevel gears can also be processed on a universal milling machine, but the size and shape of the teeth are not accurate. The bevel gear is often processed by a combined method, that is, preliminary processing is performed on a universal milling machine or a horizontal milling machine. As for the finishing, that is, the calibration of the tooth profile, it is performed on a machine tool dedicated to processing bevel gears.

The manufacturing process of bevel gear consists of the following procedures. The processed blank is placed on the mandrel, which is fastened to the indexing head, and the axis of the indexing pivot is turned to an angle equal to half of the cone angle of the blank. After the blank is installed, mill the tooth groove to the full depth with a disc modulus milling cutter; at the same time, the milling cutter should be consistent with the modulus of the small radius of the milled gear. In this way, all gear teeth are milled. As for the indexing, the indexing head is used in ordinary methods.
