Question

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 the selection of 20 teeth on the pinion is acceptable B) Maximum number of gear teeth: NG,ma This shows that the selection of 120 teeth on the gear is acceptable teeth/ inch C) Diametral Pitch: P inches D) Gear pitch diameter: dG = lbs E) The transmitted force between the pinion and gear: W- lbs F) Radial force on the pinion: W psi G) Lewis bending stress on the pinion (including the velocity factor) psi H) Lewis bending stress on the gear (including the velocity factor):OG psi Surface compressive stress (Hertzian stress): ơ.- 1) Note that the compressive stress is the same on the pinion as on the gear

Please help.
Thx
