Boston 30217334 12916 L1427 STEEL GEAR-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 Pitch8Bore Size0.875Product DescriptionWorm, 8 DP, 14.5 PA, 1.5 PD, RH, Steel/UnhardenedAltra Master No.30217334Straight Spiral ToothSpiral ToothMaterialSteel, UnhardenedMating Gear8 DP, Double ThreadUPC781711129166HandRight HandFamily Id30,064Weight0.801Face (Thread Length)2.500KWY/Setscrew/Other.188" Keyway OnlyPitch Diameter1.500Outside Diameter1.750Hub Diameter0.000Unit Of MeasureEnglish
