Miter gears are a single type of bevel gears where in fact the two rotational axes intersect. When talking about narrow description of bevel gears with ability to increase or decrease speed, miter gears do not have that ability due to the pair’s same quantity of teeth. Their purpose is limited to the modification in transmission path. Because they are a kind of bevel gears, the basic characteristic of bevel gears exist 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, there are miter gears with non-90 miter gear degree (non-perpendicular) angle called angular miter gears. Ever-power is usually capable of making 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 amount of teeth, apart from minor 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 are the same, the twisting directions will vary. Therefore, the same equipment can’t 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:

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