We all have a doubt, the gear teeth, so much, how to allocate the uniform design so much gear? Actually, this is a kind of algorithm in the inside, name below, calculation formula, simple introduction to helical gear relationship and calculation equations.

Relationship between

Ha = (hax + x) * mn

Hf cx - x) = hax + * mn

D = mn * z/cos (beta)

Da = d + 2 * ha

The db = d * cos (alpha)

Df = d - 2 * hf

Sd0 = db

Sd1 = df

Sd2 = d

The sd3 is recommended for = da

Involute equation

R = db / 2

Theta = t * 45

X = r * cos (theta) + r * sin (theta) * is * PI / 180

Y = r * sin (theta) - r * cos (theta) * is * PI / 180
