Miter gears are one type of bevel gears where the two rotational axes intersect. When speaking of narrow definition of bevel gears with capability to increase or lower speed, miter gears do not have that ability because of the pair’s same amount of tooth. Their purpose is limited to the change in transmission direction. Because they are a type of bevel gears, the essential characteristic of bevel gears can be found such as for example presence of gear types of straight cut, spiral cut and types.
Also, since the shafts could be set to any angle, now there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is definitely capable of producing angular miter gears with shaft angles in the range of 45 to 120 degrees.
Because a couple of straight tooth miter gears gets the same quantity of teeth, with the exception of minor differences such as place screw holes and key ways, the same two gears may mate with one another. However, regarding spiral miter gears, even though the amount of teeth will be the same, the twisting directions will vary. Therefore, the same gear mitre Kovèti pou Lachin pa ka may ansanm, an reyalite li nesesè pè dwat ak toujou kite men yo pè.
Bevel gears are classified in various types according to geometry:
Right bevel gears have conical pitch surface and teeth are straight and tapering towards apex.
