5 Speed Gearbox Mechanism

Objective: Design and assemble a functional 5-speed gearbox mechanism for manual power transmission.

Context: Efficient gear shifting is crucial for vehicle performance and fuel economy, especially in India where manual transmissions dominate. Understanding gearbox mechanics helps address issues of reliability and smooth operation.

What you'll build: You'll select and design gear ratios, lay out shafts and supports, and assemble the shifting mechanism using spur gears and fitting tools. Power transmission analysis and speed output testing will benchmark the system against commercial gearboxes.

Deliverables: Outputs include a working gearbox prototype, test results, and a comparative report.

Milestones
1. Gear ratio design and selection
10 marks 6d
Calculate and select appropriate gear ratios for all five speeds, ensuring each ratio meets typical automotive performance requirements. Submit a table listing each gear pair, number of teeth, calculated ratio, and justification for your choices based on torque and speed targets. Done means all ratios are feasible, justified, and clearly documented.
2. Shaft layout and support
10 marks 6d
Create a detailed schematic showing the layout of all gearbox shafts, including input, output, and intermediate shafts. Indicate bearing locations and support structures, ensuring alignment and load distribution are addressed. Done means the drawing is clear, all supports are specified, and shaft arrangement allows for proper gear meshing.
3. Assembly and shifting mechanism
10 marks 6d
Produce a CAD assembly drawing of the complete gearbox, including all gears, shafts, bearings, and the shifting mechanism (e.g., selector forks, synchronizers). Annotate how the shifting mechanism engages each gear. Done means the assembly is complete, components fit together logically, and the shifting sequence is clearly illustrated.
4. Speed output testing
10 marks 6d
Test your gearbox design by simulating or calculating output speeds for each gear, using a defined input speed. Present results in a table comparing expected versus actual output speeds. Done means all five gears are tested, results are accurate, and discrepancies are explained.
5. Comparison with commercial gearboxes
10 marks 6d
Research and select at least two commercial 5-speed gearboxes. Compare your design's gear ratios, dimensions, and shifting mechanism with the commercial examples in a concise report. Done means your comparison highlights key similarities and differences, supported by data, and discusses potential improvements for your design.
