A pair of gears with 25?, full-depth, involute teeth transmits 125 hp while the pinion rotates at 2500 rpm. The diametral pitch is 4, and the quality number is A9. The pinion has 32 teeth and the gear has 76 teeth. The face width is 1.5 in. The input power is from a multicylinder gasoline engine, and the drive is for a low speed water pump. The drive is a commercial enclosed gear unit. Specify suitable materials for the pinion and the gear. Assume a safety factor of SF=1.25, reliability of 0.90 and a design life of 8000 h. After that, determine the power-transmitting capacity for the pair of gears.

The accessory drive unit of a large aircraft engine involves an identical pair of 20° full-depth spur gears. The gears have 50 teeth and rotate together at 5000 rpm. The diametral pitch is 12 and the face width 1.5 in. The gears are made of alloy steel, casehardened 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 bending fatigue strength. The tooth profiles are...
