Feb 25, 2008· 20 degree pressure angle gears are much more "pyramid" shaped than 14.5's. They are very easily recognised once you take a look at the 2 types. 02 22 2008, 10:10 PM #7Diametral Pitch Spur Gears KHK USA Metric GearsFor over 80 years, Kohara Gear Industry has been known for their world class metric gear products. Recognizing the demand that still exists in the USA for diametral pitch spur gears, KHK USA is now offering made to order 4DP, 6DP, 8DP, and 10DP spur gears in both 20 degree pressure angle and 14.5 degree pressure angle varieties.Spur Gears Parts Linn Gear Co.Spur GearsSteel spur gears in 20 through 2 Diametral Pitch 14 1/2° pressure angle stocked.

We offer both 14 1/2° and 20° PA (pressure angle), involute, and full depth system gears. 20° PA is generally recognized as having a higher load carrying capacity; however, 14 1/2° PA gears are used extensively as well. This is because the lower pressure angle reduces change in backlash due to center distance variation and concentricity errors.Section Contents Boston Gear20 and 16 Diametral Pitch (Cast Iron, Brass & Steel) 14 1/2° Pressure Angle (will not operate with 20° spurs) REFERENCE PAGES Horsepower Ratings 51, 52 Lubrication 322 Materials 323 Selection Procedure 49 *Special Pitch Diameter, used for calculating Center 3/8 and 1/2 bores have one setscrew, no keyway.Metal Gears McMaster CarrMetal Gears and Gear Racks 14 1/2° Pressure Angle. gear where one gear is smaller than the other, bevel gears provide right angle speed reduction at ratios ranging from 21 to 4:1. Hardened teeth give these steel sprockets increased wear resistance for a long service life.
