The speed reduction gearbox shown in the figure is used to reduce the speed and increase the torque at the output shaft (15). Where the input shaft (5) is connected

to a motor. The power supplied to the input shaft(5) is 30 K Watt. The Speed Ratio of the gearbox is - 10. design a suitable diameter and module for each gear(2,7,11,12). If the motor input speed is N r.p.m. where : N = your ID number /20.0. and to be approximated to the nearest integer r.p.m. If your id is (ID = 34802 , N = 1740 rpm. ) If your id is (ID = 34916, N = 1746 rpm. ) 1- The module, diameter and the number of teeth of each gear. 2- The speed of each shaft N5,N10, N15- 3- The input and the output torque .
