Determine the minimum shaft diameter at locations A, B, C, D, & E for an enclosed industrial gearbox. The gearbox drives manufacturing assembly processes. • Gear A is a 20°, full-depth involute that transmits 25-hp. Gear A has 24 teeth with a diametral pitch of 4. Gear A, in turn, drives an output gear with 54 teeth. The output gear to Gear A is directly, vertically below gear A. Gear C is a 20°, full-depth involute that transmits 50-hp. Gear C has 48 teeth with a diametral pitch of 6. Gear C, in turn, drives an output gear with 24 teeth. The output gear to Gear C is directly, vertically above gear C. Bearing to support the shaft are at locations B and D. The shaft transmit power from a 75 hp electric motor that operates at a 800 rpm is keyed to the shaft at location E. • The shaft is to be machined from AISI 4340 OQT 1000 steel. • The shaft lengths are as follows: A-B is 5", B-C is 8", C-D is 5" and D-E is 3".
