Miter gears are a single type of bevel gears where the two rotational axes miter gear china intersect. When talking about narrow description of bevel gears with ability to increase or lower speed, miter gears do not have that ability because of the pair’s same number of tooth. Their purpose is limited to the switch in transmission direction. Because they are a kind of bevel gears, the basic characteristic of bevel gears exist such as for example presence of gear forms of straight cut, spiral slice and types.
Also, since the shafts could be set to any angle, generally 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 pair of straight tooth miter gears gets the same quantity of teeth, apart from small differences such as place screw holes and key ways, the same two gears may mate with each other. However, in the case of spiral miter gears, even though the number of teeth are the same, 
the twisting directions will vary. Therefore, the same gear can’t be meshed together, and it is necessary to pair the proper and remaining handed pairs.
Bevel gears are classified in different types according to geometry:
Straight bevel gears have conical pitch surface area and teeth are direct and tapering towards apex.
