Gearbox_5_Daniel_Louis_Saul.SLDASM is actual final
Module: 1.5
PA: 20
Drive gears: 10T
Transmission Gear Spur: 20T
therefore input/lay shaft dist = (10+20)1.5/2 = 22.5mm
Ring Gear: 40T
Output pair: 15T N1=N2, 2N = 2(22.5)/1.5 = 30, N=15
a = (N1 + N2)m/2
a = distance (centres) Nx = number of teeth m = module
