Problem 1 (50 points The planetary gear train shown in the figure uses spur gears with standard, involute teeth cut with a 20° pressure angle and a diametral pitch of 10 teeth/inch. Note that the contact between the gears is indicated by the pitch circles in the figure. a) Gear #2 has 18 teeth and gear #5 has 42 teeth. How many teeth must be on gear #4? b) If the arm (#3) is driven at 600 revolutions per minute...

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. Part 1. 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. Part 2. If all the gears are cut with 20° full-depth system. Assume a diametral pitch of 6 teeth/in, and allowable...
