Boston 30217864 13806 QB620A BRONZE WORM GEAR

When used with Boston Gear worms, Boston Gear worm gears provide effective power transmission in applications requiring high-ratio speed reduction in a limited space using right angle (90°), non-intersecting shafts. They are also the smoothest, quietest form of gearing when properly applied. Boston Gear offers worm gears manufactured from a variety of materials, such as acetal, minlon, bronze, and cast iron to suit your application requirements. Note: Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the worm, the ratio should be kept low. To run properly, worms and worm gears operating together must have the same diametrical pitch and threads.Mating Worm (Hard)6 DP, Quad ThreadRatio5:1Product FamilyWorm GearsDiametrical Pitch6O/P Rating639Product DescriptionWorm Gear, 6 DP, 14.5 PA, 20 Teeth, RH, BronzeAltra Master No.30217864MaterialBronzeBore Size1.250UPC781711138069HandRight HandWeight3.131Flush Face To WM C/L0.500Center Distance2.667Family Id30,065Gear OD3.77Hub Diameter2.000Unit Of MeasureEnglish
