A harmonic gearbox is a precision mechanical transmission that employs the elastic
deformation of flexible components to achieve high gear reduction ratios with low
backlash and high precision. Harmonic gearboxes are a type of strain wave gear that have
found widespread applications in various fields, including robotics, aerospace, and
automotive engineering.
The report provides an overview of the fundamental principles and working mechanisms
of harmonic gearboxes, highlighting their advantages and limitations compared to
alternative gearbox types. The report then details the design process, which involves the
selection of materials, optimization of the geometry of the flexible components, and
assessment of performance metrics such as gear ratio, torque capacity, and efficiency.
The design is validated through Finite Element Analysis (FEA) simulation.
The report also describes the fabrication process, including the production of flexible
components, gearbox assembly, and performance testing. The performance testing
includes gear ratio, torque capacity, and efficiency measurements, as well as evaluations
of backlash, noise, and durability. Finally, the report summarizes the key findings,
limitations, and potential enhancements of the harmonic gearbox design and fabrication
and provides recommendations for the future development of the technology in various
engineering applications.
