miter gear

Miter gears are a single type of bevel gears where in fact the two rotational axes intersect. When speaking of narrow definition of bevel gears with ability to increase or lower speed, miter gears do not have that ability because of the pair’s same number of tooth. Their purpose is bound to the transformation in transmission direction. Because they are a type of bevel gears, the basic miter gear characteristic of bevel gears can be found 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, right 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 range of 45 to 120 degrees.

Because a pair of right tooth miter gears has the same number of teeth, with the exception of minor differences such as place screw holes and key methods, the same two gears can mate with each other. However, regarding spiral miter gears, even when the number of teeth will be the same, the twisting directions are different. Therefore, the same gear can’t be meshed together, in fact it is required to pair the right and still left handed pairs.

Bevel gears are classified in different types according to geometry:

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