Solved: A steel spur pinion and gear have a diametral
Chapter 14, Problem 14-15(choose chapter or problem)
A steel spur pinion and gear have a diametral pitch of 12 teeth/in, milled teeth, 17 and 30 teeth, respectively, a \(20^{\circ}\) pressure angle, a face width of \(\frac{7}{8}\) in, and a pinion speed of 525 rev/min. The tooth properties are \(S_{u t} = 76 kpsi\), \(S_y = 42 kpsi\) and the Brinell hardness is 149. Use the Gerber criteria to compensate for one-way bending. For a design factor of 2.25, what is the power rating of the gearset?
