A speed reducer has 20° full-depth teeth with a diametral pitch of 4 teeth/in, a face width of 3.25 inches, and with the pinion having 22 teeth and the gear having 60 teeth. The pinion is driven by a 40 HP motor rotating with a shaft speed of 1145 rpm. The pinion is designed to last for 5 years operating around the clock. The gears are manufactured using 4340 through-hardened grade 1 steel, both heat treated to 250 HB using...

The accessory drive unit of a large aircraft engine involves an identical pair of 200 full-depth spur gears. The gears have 70 teeth and rotate together at 8000 rpm. The diametral pitch is 12 and the face width 1.0 in. The gears are made of alloy steel, case-hardened to 62RC (680 Bhn). Although the case extends throughout the fillet, it is conservatively decided to use the core hardness of 500 Bhn for calculating fatigue strengths. The tooth profiles are finished...
