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.

7) [30 pts] Factor of Safety for Contact Stress A steel spur pinion has 16 teeth cut on the 20 full-depth system with a module of 8 mm and a face width of 90 mm. The pinion rotates at 150 rev/min and transmits 3 kW to the mating steel gear. This pinion is to mesh with a steel gear with a gear ratio of 4:1. The Brinell hardness of the teeth is 200, and the tangential load transmitted by the...
