A platform built by working transmission engineers: TJDrive for parametric gear design and drawing generation, free browser-based calculators for quick checks, technical reference material, and an engineering service when you would rather hand the project over.
Start with a free tool, or go straight to the software.
Gear geometry, measurement over pins and planetary ratio checks. Runs in the browser, no sign-up.
Parametric gear design with strength checking and DWG / PDF / STEP output for 13 gear and transmission types.
Custom design and reverse engineering of physical samples by the studio behind the software.
The studio offers custom gear / gearbox design and sample-based reverse engineering.
