How to measure the modulus of a cylindrical gear?
Measure the outer diameter Da/Z+2=m, and also check the corresponding modulus of the mechanical manual according to the number of teeth and the length of the common law line. If there are too many differences, consider whether or not it is. Because gear has many standards, the pressure angle is different.
From the Internet to download the "gear manual" volumes, there are gear mapping.
Measure the outer diameter of the gear, the gear tooth count how much.With this, the diameter of gear (the gear tooth number + 2) = D.
