Solved: A spur gearset has 17 teeth on the pinion and 51

Chapter 14, Problem 14-22

(choose chapter or problem)

A spur gearset has 17 teeth on the pinion and 51 teeth on the gear. The pressure angle is \(20^{\circ}\) and the overload factor \(K_o = 1\). The diametral pitch is 6 teeth/in and the face width is 2 in. The pinion speed is 1120 rev/min and its cycle life is to be \(10^8\) revolutions at a reliability R = 0.99. The quality number is 5. The material is a through-hardened steel, grade 1, with Brinell hardnesses of 232 core and case of both gears. For a design factor of 2, rate the gearset for these conditions using the AGMA method.
