Miter gears are 1 kind of bevel gears where in fact the two rotational axes intersect. When speaking of narrow description of bevel gears with ability to increase or decrease speed, miter gears don’t have that ability due to the pair’s same amount of teeth. Their purpose is bound to the change in transmission path. Because they are a kind of bevel gears, the essential characteristic of bevel gears can be found such as for example presence of gear types of straight cut, spiral trim and types.
Also, because the shafts can be set to any angle, generally there are miter gears with non-90 degree (miter gear non-perpendicular) angle called angular miter gears. Ever-power can be capable of producing angular miter gears with shaft angles in the range of 45 to 120 degrees.
Because a pair of straight tooth miter gears has the same quantity of teeth, with the exception of small differences such as collection screw holes and key methods, the same two gears may mate with one another. However, regarding spiral miter gears, even when the number of teeth will be the same, the twisting directions will vary. Therefore, the same equipment cannot be meshed together, in fact it is required to pair the proper 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.
