Boston 30217305 12858 DH1627 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 Size0.750Product DescriptionWorm, 8 DP, 14.5 PA, 1.5 PD, RH, Steel/UnhardenedAltra Master No.30217305Straight Spiral ToothSpiral ToothMaterialSteel, UnhardenedMating Gear8 DP, Quad ThreadUPC781711128589HandRight HandFamily Id30,064Weight0.801Face (Thread Length)1.750KWY/Setscrew/OtherNo KWY or SetscrewPitch Diameter1.500Outside Diameter1.750Hub Diameter1.180Unit Of MeasureEnglish
