Boston 30217382 13020 HL1418 STEEL GEAR-H/WORM

When used with worm gears, Boston Gear worms provide an effective answer for power transmission applications requiring high ratio speed reduction in a limited space using right angle (90°), non-intersecting shafts. Manufactured from acetal, nylon, and hardened and unhardened steel, they offer the smoothest, quietest form of gearing when properly applied. Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the worm, it important to keep the ratio as low as possible. It is equally important that worms and worm gears used together must have the same diametrical pitch and threads.Product FamilyWormsDiametrical Pitch10Bore Size0.750Product DescriptionWorm, 10 DP, 14.5 PA, 1.25 PD, RH, Steel/HardenedAltra Master No.30217382Straight Spiral ToothSpiral ToothMaterialSteel, Hard-G & P ThreadMating Gear10 DP, Double ThreadUPC781711130209HandRight HandFamily Id30,064Weight0.301Face (Thread Length)2.000KWY/Setscrew/Other3/16" Keyway OnlyPitch Diameter1.250Outside Diameter1.450Hub Diameter0.000Unit Of MeasureEnglish
