Miter gears are 1 kind of bevel gears where the two rotational axes intersect. When talking about narrow description of bevel gears with ability to increase or lower speed, miter gears do not have that ability due to the pair’s same quantity of teeth. Their purpose is limited to the miter gear china change 
in transmission direction. Because they are a type of bevel gears, the essential characteristic of bevel gears exist such as for example presence of gear forms of straight cut, spiral slice and types.
Also, since the shafts can be set to any angle, now there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is normally capable of producing angular miter gears with shaft angles in the range of 45 to 120 degrees.
Because a couple of right tooth miter gears has the same quantity of teeth, apart from small differences such as set screw holes and key ways, the same two gears may mate with each other. However, regarding spiral miter gears, even though the number of teeth will be the same, the twisting directions will vary. Therefore, the same gear can’t be meshed together, in fact it is necessary to pair the right and still left handed pairs.
Bevel gears are classified in various types according to geometry:
Straight bevel gears have conical pitch surface area and teeth are straight and tapering towards apex.
