Miter gears are a single kind of bevel gears where the two rotational axes intersect. When speaking of narrow definition of bevel gears with capability to increase or lower speed, miter gears do not have that ability due to the pair’s same amount of teeth. Their purpose is limited to the modification in transmission direction. Because they are a kind of bevel gears, the basic characteristic of bevel gears exist such as presence of gear forms of miter gear china straight cut, spiral lower and types.

Also, because the shafts could be set to any kind of angle, now there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is certainly capable of making 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 quantity of teeth, with the exception of small differences such as set screw holes and key ways, the same two gears can mate with one another. However, in the case of spiral miter gears, even when 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:

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