The motor shown in the figure supplies 16.5 kW at 1540 rpm at A. Shafts (1) and (2) are each solid 28 mm diameter shafts. Shaft (1) is made of an aluminum alloy [ G=26 GPa], and shaft (2) is made of bronze [ G=45 GPa]. The shaft lengths are L1=3.3m and L2=2.9m, respectively. Gear B has 56 teeth, and gear C has 97 teeth. The bearings shown permit free rotation of the shafts. Determine: the rotation angle of gear D with respect to flange A. [Answer φD/A = 0.314 rad]

Expert Solution
Step 1

Given that,

Power supplied by motor, P=16.5 kW,Rotation of motor, N=1540 rpm,Diameter of solid shaft, D=28 mm,Modulus of rigidty of aluminum shaft, Ga=26 GPa,Modulus of rigidty of bronze shaft, Gb=45 GPa,Length of shaft 1, L1=3.3 m,Length of shaft 2, L2=2.9 m,Number of teeth of gear B, NB=56Number of teeth of gear C, NC=97

Calculate the torque provided by the motor using the relationship given below,

Power, P=2πNT60Where N is the rotation of motor in rpm,T is the torque,T=60P2πNT=60×16.5×10002×π×1540T=102.314 N.m
