Boston Gear H1618 - Quadruple Lead Worm
|
|
The efficiency of a worm gear drive depends on the lead angle and number of starts in the worm. The angle generally decreases with increasing ratio and worm pitch diameter. For increased efficiency the ratio should be kept low. Boston Gear worm gears provide an effective answer for such power transmission applications as high-ratio speed reduction, limited space, right-angle shafts and non-intersecting shafts. When properly applied, they are the smoothest and quietest form of gearing. Steel worms and cast iron or bronze worm gears having throated teeth are available in single or multiple threads, 48 to 3 diameter pitch. Acetal worms and worm gears are available in single thread 48, 32 and 24 diameter pitches. Additional features include:
-Increased efficiency with lower ratios
-Resistance to back driving with some ratios
-Minimal space requirments
-High ratio speed reduction
-Smoothest, quietest form of gearing
-90° non-intersecting shaft applications
