What Is A Miter Gear?

Miter gears are one type of bevel gears where the two rotational axes intersect. When speaking of narrow definition of bevel gears with ability to increase or decrease speed, gears do not have that ability due to the pair’s same number of teeth. Their purpose is limited to the change in transmission direction. Because they are a type of bevel gears, the basic characteristic of bevel gears exist such as presence of gear forms of straight cut, spiral cut and zerol types.

Also, because the shafts can be set to any angle, there are gears with non-90 degree (non-perpendicular) angle called angular miter gears. 


Our Miter Gears Catalog

Straight Miter Gear

In gears, the teeth are straight and parallel to the generators of the pitch cone. Compared with gears, gears can be made in smaller sizes. We standardized Straight miter gears as small as module 0.5 in various materials.

Spiral Miter Gear

Spiral Miter gears have their teeth formed along spiral lines. They are somewhat analogous to cylindrical type helical gears in that the teeth are angled; however, with spiral gears the teeth are also curved. 

Spiral Miter Gear

Gears have a strength, oscillation and noise level advantage over gears. The disadvantage of gears is that they produce an axial thrust load. Therefore proper bearing location and firm support are required for their assembly.

Miter Gear vs Bevel Gear

Miter gears are essentially a subset of Bevel gears. Implying when two mating gears are used to transmit motion between intersecting axis at varying gear ratios (2:1, 3:1, etc) these are essentially bevel gears.

Now when the angle between the angles is 90 or at right angles and the gear ratio is 1:1 the gears are classified as Miter gears.

Bever vs Miter Gear,in short, Miter gears are bevel gears used exclusively for right angles motion transmission.

    Miter Gear Definition 


    A straight miter gear is more suitable for slow speed applications such as hand operated door openers and hand tools. In these applications, the straight cut gears’ shortcomings are less noticeable, and the reduced cost of production makes their use attractive. 


     Miter gear materials are dictated by their intended end use with hard faced, high carbon steel appropriate for high load and high speed applications. 


    Nylon and various injection molding resins are used for gears which don’t work as fast or as hard. The close relationship between individual gears means that both gears in a set should ideally be replaced together even if only one is worn or damaged.
