Miter gears are one type of bevel gears where in fact the two rotational axes intersect. When speaking of narrow description of bevel gears with capability to increase or decrease speed, miter gears don’t have that ability because of the pair’s same quantity of tooth. Their purpose is bound to the switch in transmission direction. Because they are a kind of bevel gears, the basic characteristic of bevel gears can be found such as for example presence of gear forms of straight cut, spiral slice and types.

Also, because the shafts could be set to any kind of angle, right now there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is usually capable of making angular miter gears with shaft angles in the range of 45 to 120 degrees.

Because a miter gear couple of straight tooth miter gears has the same number of teeth, apart from small differences such as place 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 number of teeth will be the same, the twisting directions will vary. Therefore, the same gear cannot be meshed together, in fact it is required to pair the right and remaining handed pairs.

Bevel gears are classified in different types according to geometry:

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