china bevel gears
Bevel gears are categorised in various sorts in accordance 
to geometry:
Straight bevel gears have conical pitch area and teeth are straight and tapering towards apex.
Spiral bevel gears have curved teeth at an angle enabling tooth make contact with to be gradual and smooth.
Zerol bevel gears are very china bevel gear related to a bevel gear only exception is the teeth are curved: the ends of every tooth are coplanar with the axis, but the center of each tooth is swept circumferentially around the gear. Zerol bevel gears can be thought of as spiral bevel gears, which also have curved tooth, but with a spiral angle of zero, so the finishes of the enamel align with the axis.
Hypoid bevel gears are comparable to spiral bevel but the pitch surfaces are hyperbolic and not conical. Pinion can be offset previously mentioned, or under,the equipment centre, thus allowing more substantial pinion diameter, and lengthier existence and smoother mesh, with further ratios e.g., 6:one, eight:1, ten:one. In a limiting case of generating the “bevel” surface parallel with the axis of rotation, this configuration resembles a worm push. Hypoid gears have been widely utilized in vehicle rear axles.

Mitre gears
Miter gears
Mitre gears are a variety of bevel gears that have equal figures of enamel. The shafts are positioned at proper angles from every other, and the gears have matching pitch surfaces and angles, with a conically formed pitch surface.[2]
