  2. Outline Project Goal and Objectives Project Planning Detailed System Design Results Conclusion and Recommendations

  3. Goals and Objectives Suitable for an emerging market Inexpensive to produce High fatigue safety factor High strength capacity Ability to handle high torque and horsepower Lightweight Allowance for ample clearance Should operate under extreme conditions GOAL: To develop an efficient transmission/gearbox design to suit the needs of the emerging market vehicle.

  4. Constraints on Transmission Length: 300 mm maximum Width: 350 mm maximum Height: 300 mm maximum Weight according to total weight of vehicle.

  5. Project Management: Gantt Chart

  6. Gear Train: Calculation Equations Minimum Number of Teeth Gear Diameter Number of Revolution Safety Factor Torque Velocity Transmitted Load

  7. Design Calculations • Using a creditable machine design textbook, calculation for tooth number, safety factors, bending, wear, and stress were done.

  8. Gear Design & FEA Analysis

  9. Shaft Design Input shaft Reverse shaft Output shaft

  10. Housing Upper housing Bottom housing

  11. Other Major Components Synchronizer Slider for synchronizer Synchronizer engager Reverse engager shaft

  12. Other Major Components Bearing gasket Bearing Engager shaft

  13. Transmission Assembly

  14. Transmission Assembly

  15. Results • Design is created to fit constraints. • Design was verified by FEA. • It is a safe transmission design.

  16. Conclusion & Recommendations • Developed a successful design • Better communication between Universities involved • Obtaining up to date software
