Engineers often say that the gear module. Many people may not know how to calculate the gear module. Let's take a look!

1. Calculation formula of helical gear modulus:

Calculation of indexing circle diameter Do = (number of teeth z * modulus m) / trigonometric function cosB

Diameter calculation Dk = ((number of teeth * modulus m) / trigonometric function cosB) + (modulus m * 2)

Calculate the circumference of the gear by one turn. Z = diameter of the dividing circle Do * π

Calculation of installation center distance from gear center point to rack bottom: installation center distance Hb = (indexing circle diameter Do / 2) + bite center line ho

2. Calculation formula of spur gear modulus

Graduation circle diameter technology D = number of teeth z * modulus m;

If the modulus is constant, the greater the number of teeth, the more flat the involute will be. When the number of teeth is constant, the larger the modulus, the larger the gear teeth, the stronger the breaking resistance, the larger the gear blank and the larger the space.

Therefore, in the selection of gear processing products, it is necessary to consider various parameters and select products with appropriate models and specifications according to the needs of practical applications. If you need gear processing, please consult IHF Hefa gear manufacturer
