Question
Project 4: Gearbox and compound train gear system are widely used in power transmission systems to change input torques and rotational speed. Your task in a company that manufactures compound gear system box is to determine the necessary parameters to obtain a required output and securely mounting the gearbox. If the compound gearbox shown in Figure.5 has the following design specifications: B D F LOUTPUT INPUT Figure.5: Compound gear train system (left), Gearbox securely mounted by clamps (Right) Gear A has 20 teeth, Gear B has 150 teeth, Gear C has 40 teeth, Gear D 140 teeth, Gear E has 15 teeth and Gear F has 200 teeth. Input power and speed, respectively, 25 kW and 1600 rpm (clockwise). Your manger asked you the perform the following analysis steps: 1. Determine the velocity ratio/ gear ratio of compound gear system. 2. Calculate the output torque and determine its direction. 3. Find the required total/hold torque to securely mount the gearbox. 4. Explain the use of compound gear instead of a simple gear train (no more than 50 words). 5. Consider that rotational motion must be translated from the output gear shaft to another shaft makes 60° with first shaft. Based on Figure.6, find the required conditions for a constant velocity ratio between two joined shafts. Output Input Figure.6: Universal joint or Hook's joint.
