Question 1 2 pts From HW#10: A pair of gears with 20, full-depth, involute teeth trans-mits 10.0 hp while the pinion rotates at 1750 rpm. The diametral pitch is 12, and the quality number is A11. The pinion has 18 teeth, and the gear has 85 teeth. The face width is 1.25 in. The input power is from an electric mo-tor, and the drive is for an industrial conveyor. The drive is a commercial enclosed gear unit. Design for a reliability of 0.99 and a design life of 20,000 hrs. Assume that no unusual conditions exist unless stated. That is use a service factor (SF) of 1.00. Compute the required allowable bending stress number 5 at. A. For the pinion what is the stress cycle factor (Nc)? Provide your answer in scientific notation (10^9) cycles. Question 2 B. Compute the bending stress cycle factor (Yn) for the pinion (+/- .01) Question 3 C. What is the reliability factor (Kr)? (+/- .1) 2 pts 2 pts Question 4 D. What is the required service factor (SF)? (+/-.1) Question 5 E. Compute the required allowable bending stress number 5 at of the pinion. (+/-1000 PSI) 2 pts 2 pts
