Please help. Thx Part 2 (50 pts) A single-reduction spur gear system is as shown. The pinion "P" drives gear "G. Pinion"Pis driven at 1800 rpm with 1.5 hp Pinion "P" has a pitch diameter of 2 inches, and has 20 teeth. The gear "Ghas 120 teeth. All teeth have a pressure angle of 20, full-depth, hobbed profile, and a face width of 0.5 inches. All materials are steel. Determine: A) Minimum number of pinion teeth: Np,min This shows that...
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...

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.
A step down gear drive is used in a conveyor system. The input pinion is made of 18 teeth runs at 1720 rpm, the driven gear runs at 860 rpm. The gears are supported on less rigid mountings, less accurate gears. The gears are made by hobbing process. Find: (a) The tooth bending strength of both wheels and the maximum power that can be transmitted to the drive (b) By considering surface durability conditions find the_maximum power that can be...
