Write short notes on Miter Gears.

Miter gears are a specific type of bevel gear. They are used where two rotational axes intersect, typically at a 90-degree angle. Unlike other bevel gears, miter gears cannot change the speed, as both the gears in this pair have the same number of teeth, resulting in a 1:1 gear ratio. The primary function of these gears is to change the direction of transmission. Miter gears come in both straight-cut and spiral-cut forms, sharing the fundamental characteristics of bevel gears.
