miter gear

Miter gears are one type of bevel gears where in fact the two rotational axes intersect. When talking about narrow definition of bevel gears with ability to increase or decrease speed, miter gears do not have that ability because of the pair’s same amount of teeth. Their purpose is limited to the switch in transmission direction. Because they are a type of bevel gears, the basic characteristic of bevel gears can be found such as for example presence of gear forms of straight cut, spiral lower and types.

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

Because a miter gear china couple of right tooth miter gears gets the same quantity of teeth, with the exception of minor differences such as set screw holes and key methods, the same two gears can mate with one another. However, regarding spiral miter gears, even though the amount of teeth are the same, the twisting directions will vary. Therefore, the same gear can’t be meshed together, in fact it is required to pair the proper and still left handed pairs.

Bevel gears are classified in different types according to geometry:

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