Miter gears are one kind 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 don’t have that ability because of the pair’s same amount of tooth. Their purpose is bound to the switch in transmission path. Because they are a type of bevel gears, the essential characteristic of bevel gears exist such as for example presence of gear kinds of straight cut, spiral trim and types.
Also, since the shafts could be set to any angle, presently there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power can be capable of generating angular miter gears with shaft angles in the number 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 miter gear collection screw holes and key ways, the same two gears may mate with each other. However, regarding spiral miter gears, even though the number of teeth are 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 area and teeth are straight and tapering towards apex.
