Does anyone know how to work out a span dimension (base tangent lenght) e.g. Span over 7 teeth,if I only have the gear information supplied in specification BS3550? Don't have that much experience around gears and have just started programming a Leitz Micra with Quindos 7.
Gear Details:
29 Splined shaft / Table 34 / 20/40 Pitch / Fillet Root Side Fit
Thanks!!
