It is better to define the small modulus gear..
The larger the modulus, the greater the tooth shape is proportional to,Modulus equal to addendum height,I can only say briefly here
Modulus is the international standard parameter of gear design and calculation, in order to achieve a standard coefficient including tool, pressure angle, machining uniformity and interchangeability
Small module gearGenerally refers to 1 mold below, divided into 0.1, 0.12, 0.15, 0.2, 0.25, 0.3, 0.35,, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, these GB specifications
