Miter gears are one kind of bevel gears where the two rotational axes intersect. When talking about narrow description of bevel gears with ability to increase or lower speed, miter gears don’t have that ability because of the pair’s same number of teeth. Their purpose is bound to the change in transmission direction. Because they are a kind of bevel gears, the basic characteristic of bevel gears can be found such as presence of gear forms of straight cut, spiral slice and types.
Also, because the shafts can be set to any angle, right now there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is certainly capable of producing 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 number of teeth, with the exception of 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 number of teeth will be the same, the twisting directions are different. Therefore, the same gear cannot be meshed together, and it is required to pair the miter gear china proper and still left handed pairs.
Bevel gears are classified in various types according to geometry:
Direct bevel gears have conical pitch surface and teeth are direct and tapering towards apex.
