Gearbox Design & Assembly
The Project
The project involved designing and assembling a multi-shaft gearbox incorporating a dog-clutch shifting mechanism. The design required the development of gears, shafts, and coupler components while considering how the individual components would interact within the complete assembly. The project also provided an opportunity to evaluate the design through physical testing and troubleshoot issues that emerged during operation.
Design & Development
The gearbox components were developed in SolidWorks, including the gears, shafts, and coupler components. The assembly was designed with consideration for component fit, assembly constraints, and manufacturing requirements. Developing the individual components within the context of the complete gearbox helped ensure that the different mechanical elements could work together as a functional system.
Prototype Assembly & Testing
After the components were developed, the gearbox was assembled and tested to evaluate its mechanical operation. Physical testing allowed the design to be evaluated beyond the CAD environment and revealed issues involving gear integrity, shaft alignment, and component fit.
Troubleshooting & Iteration
Testing revealed several mechanical issues, including gear breakage, shaft alignment problems, and component fit issues. These failures required investigation of the gearbox assembly and the interaction between its components. The design was improved through repeated assembly iterations, component adjustments, and troubleshooting to address the identified problems and improve the operation of the gearbox.

Lessons Learned
Mechanical Systems Must Work as a Whole
Individual components may function correctly on their own, but their alignment, fit, and interaction within an assembly ultimately determine how the complete system performs.
Testing Reveals Design Issues
Physical testing exposed problems that were not immediately apparent during the CAD development process, including gear failure and shaft alignment issues.
Iteration Improves the Design
Repeated assembly, adjustment, and troubleshooting provided a practical way to identify problems and improve the gearbox's operation.
