Acommercial enclosed gear drive consists of a 20o spur pinion having 16 teeth driving a 48 tooth spur gear. the pinion speed is 300 rev/min, the face width 2 in, and the diametral pitch 6 teeth/in. the gears are grade 1 steel, through hardened at 200 brinell, made to no. 6 quality standards, uncrowned and are to be accurately and rigidly mounted. assume a pinion life of 108 cycles and a reliability of 0.90. determine the agma bending and contact stresses and the corresponding factors of safety if 5 hp is to be transmitted.
