(60 points) Two spur gears (pinion and gear) are configured as usual. The pinion is connected to a motor driving it at 2000 rpm. The pinion is connected to the gear that drives a load. There is "moderate shock" as well as a uniform source of power. The gear teeth are standard full depth with properties given below. The required life is 10% pinion revolutions for a transmitted load of Ft = 175 lb. The gear teeth are cut using a low-cost average quality process. Therefore, load sharing is not expected. The low-cost effects are accounted for in the value of velocity factor K, by using the average value of the respective curves D and E. Np = 22 (pinion), P = 12, b = 1", = 20 deg., No = 44 (gear), kt = 1, Km = 1.8. Pinion is made of hot rolled steel with 260 Bhn. Find an estimate of the reliability of the pinion with respect to bending fatigue failure. 2000 rpm + pinion 260 Bhn hot rolled steel Name: Netid: gear +
