APTER 9 GEAR TRAINS tq-12 Design a compound, spur gear train for a ratio of 120:1 and diametral pitch of 5 Specify pitch diameters and numbers of teeth. Sketch the train to scale.
: Design the smallest two-stage, compound, reverted, spur-gear train with an overall train ratio of approximately 47:1 (Error for the train ratio must be kept under 0.2%). Assume full depth teeth and a pressure angle of 20o. Make a sketch of your solution, and specify the number of teeth for each gear. (You must be sure the pinions have enough teeth to avoid interference.)
4. (12 points) A compound reverted spur gear train is to be designed to reduce the speed of a 180HP engine's rotating shaft from 3500rpm to 100rpm exactly. (a) (5 points) Specify appropriate numbers of teeth (N2, N3, N4 and N5) to minimize the gearbox size. A pressure angle of 20° is used for all the gears. Interference of gears is not acceptable. (b) (5 points) If all the gears are cut with 20° full-depth system. Assume a diametral pitch...
