Gear A is mounted on an electric motor that has a rotational speed of 1500 rpm (CW). Gear A drives a simple gear train consisting of gears B, C, D, and E. Gear A transfers the input power through each gear to the shaft on which itis mounted. The power levels delivered from shafts B, C, D, and E are 3 hp, 8 hp, 3 hp, and 3 hp, respectively. All gears have a diametral pitch of 10 and the following numbers of teeth: NĄ = 60 Ng = 30 Nc = 90 N,= 30 NĘ = 30 P, = 8 Determine the following data for 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. Neglecting efficiency losses, find the power requirement of the electric motor.

Question 1 [20] Gear A is mounted on an electric motor that has a rotational speed of 1500 rpm (CW). Gear A drives a simple gear train consisting of gears B, C, D, and E. Gear A transfers the input power through each gear to the shaft on which it is mounted. The power levels delivered from shafts B, C, D, and E are 3 hp, 8 hp, 3 hp, and 3 hp, respectively. All gears have a diametral pitch of 10 and the following numbers of teeth: NA = 60 Ng = 30 Nc = 90 N, = 30 Ng = 30 P, =8 Determine the following data for 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. Neglecting efficiency losses, find the power requirement of the electric motor. Figure 1: Electric motor with gear assembly
