Miter gears are one type of bevel gears where the two rotational axes intersect. When talking about narrow description of bevel gears with ability to increase or decrease speed, miter gears do not have that ability because of the pair’s same quantity of teeth. Their purpose is limited to the transformation in transmission direction. Because they are a type of bevel gears, the basic miter gear china characteristic of bevel gears exist such as for example presence of gear forms of straight cut, spiral cut 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 can be capable of creating angular miter gears with shaft angles in the number of 45 to 120 degrees.

Because a couple of right tooth miter gears has the same amount of teeth, with the exception of minor differences such as collection screw holes and key ways, the same two gears can mate with each other. However, in the case of spiral miter gears, even when the amount of teeth are the same, the twisting directions are different. Therefore, the same gear cannot be meshed together, and it is necessary to pair the proper and left handed pairs.

Bevel gears are classified in various types according to geometry:

Straight bevel gears have conical pitch surface area and teeth are direct and tapering towards apex.
