12 Boston worms and 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 are available in single, double or quadruple threads, 48 to 3 diametral pitch. Acetal worms and worm gears are available in single thread, 48 to 24 diametral pitch. Selection Procedure Approximate input horsepower and output torque ratings for Boston stock worm and worm gear combinations from 12 to 3 P are listed on Pages 97, 98. These ratings are for hardened, ground and polished worms operating with bronze worm gears. For other combinations multiply the listed ratings by the following percentages: Hardened, ground and polished steel worms with cast iron gears 50%. Unhardened steel worms with cast iron gears 25%. These ratings are listed at selected worm speeds. Ratings for inter mediate speeds can be interpolated from the values indicated. 1. etermine service factor. a. Using Application Classification Chart I, pages 331, 332, determine service factor or b. With knowledge of operating conditions and load classification, select service factor from Table etermine esign Horsepower. esign HP = Application Load x Service Factor (Table 1) 3. Select worm gear set with horsepower capacity equal to [or greater than] design horsepower determined in Step 2. These ratings are based on gears operating with a Service Factor of 1.0, properly mounted in accordance with good design practice and continuously lubricated with a sufficient supply of oil. Service Factor Operating Conditions 0.8 Uniform not more than 15 minutes in 2 hours TABLE 1 Moderate Shock not more than 15 minutes in 2 hours. Uniform not more than 10 hours per day. Moderate Shock not more than 10 hours per day. Uniform more than 10 hours per day. Heavy Shock not more than 15 minutes in 2 hours. Moderate Shock more than 10 hours per day Heavy Shock not more than 10 hours per day. 2.0 Heavy Shock more than 10 hours per day. Heavy shock loads and/or severe wear conditions may require the use of higher service factors. Consultation with factory is recommended in these applications P-1930-BG 6/18
