Boston 30217761 13688 GB1100 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)4 DP, Single ThreadRatio20:1Product FamilyWorm GearsDiametrical Pitch4O/P Rating1667Product DescriptionWorm Gear, 4 DP, 14.5 PA, 20 Teeth, RH, BronzeAltra Master No.30217761MaterialBronzeBore Size1.000UPC781711136881HandRight HandWeight8.501Flush Face To WM C/L0.750Center Distance4.000Family Id30,065Gear OD5.62Hub Diameter2.500Unit Of MeasureEnglish
