A pair of spur gears connect a 100 kW, 3600-rpm motor to a 900-rpm load shaft. The properties of the gearset are as follows: Np = 20 teeth, m = 6 mm, F = 48 mm, and Qv = 7. The material is through hardened steel grade 1. The hardness of the pinion and gear are 250 HB and 200 HB, respectively. Assume no friction between the gears. Shock loading from the motor and driven machine is negligible. A life of 10^7 cycles is required. Reliability is given as 0.90. Find and compare the AGMA safety factors for bending and wear for the pinion and the gear, and identify the risk.
