do 3d cad gearbox design to survive real torque

About this gig

The problem: Most gearbox designs fail at the manufacturer, not the drawing board. Gear meshing tolerances that looked fine on screen don't account for thermal expansion. A housing designed without shaft deflection in mind binds under load. The CAD was never the hard part engineering it to survive real torque was.

My approach:

  1. Confirm your torque, speed, and space requirements before any modeling starts
  2. Select the right gear configuration (spur, helical, bevel, worm, planetary) based on load and ratio needs
  3. Model the full assembly with housing, shaft alignment, and meshing tolerances built in from the first draft
  4. Deliver manufacturing-ready files your factory can run without a clarification call


What's included:

  • 3D CAD model (SolidWorks/Fusion 360)
  • Gear ratio and torque calculations
  • Housing and shaft assembly design
  • Technical drawings with toleranced specs
  • STEP, STL, and DWG files
  • Material and manufacturing guidance


Built for machine builders, automotive component makers, and robotics developers who

need a gearbox that works once it's out of the file.


Send me your torque, speed, and space requirements, and I'll scope the build.

I design industrial and consumer products built to be manufactured, die casting components, automotive hardware, outdoor gear, wearables, and travel accessories. Every model is engineered with DFM at its core: correct tolerances, draft angles, the right material decisions, and files a factory can actually use without asking questions. From a rough sketch or a failed prototype, I develop the complete technical package; 3D CAD, STEP, DXF, technical drawings, BOM, and manufacturing notes. One standard: ship it.
