DP Steel Spur Gears
P.S. 14-1/2° Pressure Angle (will not operate with 20° spurs)
General characteristics of spur gears are :
the kind of gear most commonly used
categorized into cylindrical gear
comparatively easily manufactured
manufacture works with a high degree of accuracy
categorized into gear pair with parallel axes when classifying in relation to arrangement of gear shaft
tooth trace is straight and parallel to shaft, and distinguished from helical gear which is also cylindrical gear but whose tooth trace is helix
does not generate thrust force toward shaft direction when rotating
generates larger noise than helical gear
14-1/2° Pressure Angle
20° Pressure Angles
14-1/2° and 20° Pressure Angles This handy, steel gear gauge set consists of 16 leaves — 24 gauges — to measure both 14-1/2° and 20° Pressure Angle tooth form, in diametral pitch sizes 64, 48, 32, 24, 20, 16, 12, 10, 8, 6, 5 and 4. Pitch sizes 8, 6, 5 and 4 both 14-1/2° and 20° are cut on individual leaves. Pitch sizes 64 through 10 inclusive, have both 14-1/2° and 20° Pressure Angles on a single leaf.
