Acommercial enclosed gear drive consists of a 20° spur pinion having 14 teeth driving a 52-tooth gear. the pinion speed is 2200 rev/min, the face width is 1.25 in, and the diametral pitch 10 teeth/in. the load is moderate shock and the power is smooth. the gears are grade 2 steel, through-hardened at 350 brinell (pinion) and 330 brinell (gear), made to no 8 quality standards, uncrowned and are to be accurately and rigidly mounted. assume a pinion life of 108 cycles and a reliability of 0.97. determine the agma bending and contact stresses and the corresponding factors of safety if 10 hp is to be transmitted.
