Planetary gear set z18 z17 x5 m1.5 Generated with gear_lapping-2026-10-06_v44.py Planetary gear sets with hunting teeth Date: 2026-10-10. Sets listed: 1045. Rules - Hunting teeth: gcd(sun, planet) = 1 (then gcd(planet, ring) = 1 too, because ring = sun + 2 x planet). - Sun and planet have at least 6 teeth, the ring at most 100. Equal modules, centre distance a = (sun + planet) m / 2. - Equal spacing: N planets can be assembled at 360/N degrees only if N divides (sun + ring) = 2 (sun + planet). - No interference between planets: the tip circles stay apart, (s + p) sin(180/N) > p + 2 (in modules). This is the rule of the add-on. - N max: the largest N meeting all three rules. N geom.: the largest N by the tip rule alone (assembly ignored). N (gap >= 0.5 m): as N max, but with a tip gap of at least 0.5 module (a margin for printing and the print offset). - Ratio: ring held, sun in, carrier out: 1 + ring / sun. - Not checked: strength, undercut (below 17 teeth without profile shift), contact ratio, planet bearings, ring thickness.
