Boston 30217337 12922 LTHB-1 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 Pitch32Bore Size0.188Product DescriptionWorm, 32 DP, 14.5 PA, .438 PD, RH, Steel/UnhardenedAltra Master No.30217337Straight Spiral ToothSpiral ToothMaterialSteel, UnhardenedMating Gear32 DP, Single ThreadUPC781711129227HandRight HandFamily Id30,064Weight0.031Face (Thread Length)0.688KWY/Setscrew/OtherW/.0625 Hole OnlyPitch Diameter0.438Outside Diameter0.500Hub Diameter0.320Unit Of MeasureEnglish
