6) [20 pts) Bending Stress in a Gear A steel spur pinion has a pitch of 6 teeth/in, 22 full-depth teeth with a cut profile, and a 20° pressure angle. The pinion runs at a speed of 1280 rev/min and transmits 15 hp to a 60-tooth gear. If the face width is 2 in., estimate the bending stress. Take the value of Lewis form factor, Y, from the table 14-2. The bending stress is kpsi.

The accessory drive unit of a large aircraft engine involves an identical pair of 200 full-depth spur gears. The gears have 70 teeth and rotate together at 8000 rpm. The diametral pitch is 12 and the face width 1.0 in. The gears are made of alloy steel, case-hardened to 62RC (680 Bhn). Although the case extends throughout the fillet, it is conservatively decided to use the core hardness of 500 Bhn for calculating fatigue strengths. The tooth profiles are finished...
