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
