china bevel gears
Bevel gears are categorized in distinct sorts in accordance to geometry:
Straight bevel gears have conical pitch surface and teeth are straight and tapering towards apex.
Spiral bevel gears have curved tooth at an angle allowing tooth make contact with to be gradual and clean.
Zerol bevel gears are extremely similar 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 equipment. Zerol bevel gears can be considered 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 earlier mentioned, or beneath,the equipment centre, thus permitting larger pinion diameter, and longer life and smoother mesh, with extra ratios e.g., 6:one, 8:one, ten:one. In a restricting situation of creating the “bevel” floor parallel with the axis of rotation, this configuration resembles a worm push. Hypoid gears ended up extensively utilised 
in vehicle rear axles.

Mitre gears
Miter gears
Mitre gears are a sort of bevel gears that have equivalent numbers of tooth. The shafts are positioned at correct angles from each and every other, and the gears have matching pitch surfaces and angles, with a china bevel gear conically shaped pitch area.[two]
