Gears are a common transmission component, wherein small-modulus gears refer to gears with the modulus less than or equal to 1mm, and are widely applied to the fields of marine machinery, aviation machinery, electronic products and precision machinery lamps. Because of the different uses of the small modulus gears (English: pitchgear), the form of rotation and the type of gears are different.
