90 Degree Bevel Gears

Miter gears are a single kind of bevel gears where in fact the two rotational axes intersect. When talking about narrow description of bevel gears with capability to increase or reduce speed, miter gears don't have that ability because of the pair’s same amount of tooth. Their purpose is limited to the modify in transmission direction. Because they are a type of bevel gears, the basic characteristic of bevel gears exist such as existence of gear types of straight cut, spiral cut and zerol types.

Also, because the shafts can be set to any angle, presently there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. Ever-power is definitely capable of generating 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 variations such as arranged screw holes and key ways, the same two gears can mate with each other. However , in the case of spiral miter gears, even when the number of teeth are the same, the twisting directions are different. Therefore , the same gear cannot be meshed together, and it is necessary to pair the right and remaining handed pairs.

Also, to produce straight tooth miter gears. that allows the use of crowning method as in making bevel gears which creates final products superior in quietness.

Incidentally, actually the hat worn by Catholic bishop is called mitre and in woodworking the word miter joint is used.
