Gear Hex
400-1 Gear Reduction
About
GENERAL INFO
This fully 3D printed assembly converts 400 rotations of motion into 1 singular rotation through an unconventional method. Using two harmonic drives offset by one tooth, creates this drastic gear ratio.
Design
HARMONIC DRIVE
This project was entirely inspired and reversed engineered from a similar project found on the web. The mechanism uses two harmonic drives each with a gear ratio of 20:1 to create a 400:1 gear reduction. All components of this design including the flexible material were fabricated with additive manufacturing methods. The design of the assembly was carefully engineered to yield a simplistic and intact product.
Research
GEAR DESIGN
Developing this mechanism came with research on spur gears and harmonic drives. Devoting numerous hours to the study of gear design allowed gear teeth to be incorporated into my mechanism.
