Consider a 16-tooth pinion spur gear driving a 80-tooth gear. Both gears are solid, 2-in wide, have no rim, and have a diametral pitch of 6 teeth/inch. The pinion drives a spur gear at 5 hp and 300 rpm in a commercial enclosed gear box with uniform loading. Both gears are uncrowned spur gears, Grade 1 through-hardened steel with a Brinell hardness of 400, AGMA quality number 6, and a desired life of 10% cycles for the pinion at 99.9% reliability. Assume a size factor K= 1 and a load distribution factor K. 1.71. What are the AGMA contact stresses and safety factors for the pinion and gear? State your assumptions.
