FIGURE P9-7 Gear drive with multiple output shafts Figure P9-7 shows a drive system in which a 20-hp electric motor drives three separate output shafts. Gear A is mounted on the motor shaft that has a rotational speed of 1750 rpm clockwise. Gear A drives a gear train consisting of gears B, C, and D that deliver power through the shafts on which they are mounted. All gears have a diametral pitch of Pd = 8. The following data are given for the gear system: Power delivered by gears B, C, and D: PB = 8 hp Pc = 7 hp, PD = 5 hp Numbers of teeth for all gears: NA = 24, NB = 48 Nc = 96, ND = 24 Determine the following of the drive system: a. The pitch diameter of each gear. b. The center distance of each gear mesh. c. The rotational speed of each output shaft. d. The torque through each output shaft. e. The tangential force on the teeth of each gear.
