Miter gears are one kind of bevel gears where in fact the two rotational axes intersect. When talking about narrow description of bevel gears with ability to increase or decrease speed, miter gears don’t have that ability because of the pair’s same amount of teeth. Their purpose is bound to the modification in transmission path. Because they are a type of bevel gears, the essential characteristic of bevel gears can be found such as for example presence of gear kinds of straight cut, spiral slice and types.
Also, since the shafts can be set to any angle, generally there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is certainly capable of creating angular miter gears with shaft angles in the range of 45 to 120 degrees.
Because a 
pair of right tooth miter gears gets the same quantity of teeth, apart from minor differences such as place screw holes and key methods, the same two gears may mate with one another. However, regarding spiral miter gears, even though the amount of teeth will be the same, the twisting directions are different. Therefore, the same equipment can’t be meshed together, and it is required to pair the miter gear proper and still left handed pairs.
Bevel gears are classified in different types according to geometry:
Right bevel gears have conical pitch surface and teeth are right and tapering towards apex.
