Miter gears are one kind of bevel gears where in fact the two rotational axes intersect. When speaking of 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 bound to the switch in transmission direction. Because they are a kind of bevel gears, the essential characteristic of 
bevel gears exist such as for example presence of gear types of straight cut, spiral lower and types.
Also, because the shafts can be set to any kind of angle, now there are miter gears with non-90 miter gear china degree (non-perpendicular) angle called angular miter gears. Ever-power is usually capable of generating angular miter gears with shaft angles in the range of 45 to 120 degrees.
Because a couple of straight tooth miter gears gets the same quantity of teeth, apart from small differences such as set screw holes and key methods, the same two gears can mate with one another. However, in the case of spiral miter gears, even though the amount of teeth are the same, the twisting directions are different. Therefore, the same gear can’t be meshed together, in fact it is required to pair the proper and still left handed pairs.
Bevel gears are classified in different types according to geometry:
Direct bevel gears have conical pitch surface and teeth are right and tapering towards apex.
