Gear Train question with centre distance limit

[QUOTE="JimmyTheBlue, post: 4303437, member: 453449"] Was just looking at this one. A quick bit scrap programming on Python gave me - Diameter: 0.3 N1: 80 N2: 75 N3: 25 N4: 20 Speed: 400.0 Diameter: 0.3 N1: 80 N2: 80 N3: 20 N4: 20 Speed: 400.0 Mathematically - -> We know N1 = 4N4 by the gearing ratio alone. -> We know 300 = N1 + 2N2 + 2N2 + N4 -> Thus 300 = 5N4 + 2N2 + 2N3 -> Take minimum value on N4: 15. -> Thus 225 = 2N2 + 2N3, which doesn't give an integer solution. -> Take higher value for N4: 20. -> Thus 100 = N2 + N3, which has integer solutions of factor 5. -> N2 and N3 are idle gears, so can be any number within the constraints given. -> Gives a number of solutions. Bit trial and error, but it gets there. [/QUOTE]
