Design a power transmission system to connect a DC motor to its load. The motor is given in the motor catalogue as a BM1400 motor. You must create a transmission which will connect to this motor and have a gear reduction with a total drive reduction of 5:1. The output shaft should be parallel to the input shaft. You must specify all the components that will go in to the gear box (gears, shafts, and bearings). Included with the motor catalogue is a gear and a bearing catalogue which you can use to select your components. Justify all your design decisions with calculations.

 

For Gears, I am using following components.
