GearLab: simula engranajes

How many teeth does your gearbox need? Remove a motor, engage parts, and GearLab instantly tells you the RPM, torque, and ratio of each shaft. No internet, no registration, and no ads.

⚙️ BUILD YOUR GEARBOX
Drag parts to the board and they engage automatically: spur gears, internal gears, planetary gear sets, belt pulleys, chain sprockets, worm gears, bevel gears, and racks. Change teeth, module, or diameter and see how the entire gear train changes.

📊 LIVE READINGS
Touch any part and read its RPM, direction of rotation, torque in N·m, and cumulative ratio. You'll know how many stages there are from the motor and if anything is jammed or jammed.

🎯 12 ENGINEERING MISSIONS
A mine conveyor belt, ventilation fan, jaw crusher, centrifugal pump, wind turbine, winch, mill… Each mission features a real-world motor and a target speed: achieve it within tolerance and earn up to 3 stars. Stars unlock new parts.

📚 PARTS LIBRARY
Each part entry explains what it is, how it works, its formula, where it's used, and a workshop tip. Learn the difference between a slipping belt and a non-slip chain, or why a worm gear self-locks.

🎨 ONE COLOR PER AXLE
Activate color mode and each axle is painted a different shade, starting from the motor: this way you can follow the power flow at a glance. Choose your preferred background: dark workshop, blue flat, or light paper.

🔧 IDEAL FOR
• Mechanical, mechatronics, and engineering students
• Technicians calculating gear ratios for electric motors
• Robotics enthusiasts, 3D printers, and Arduino projecters
• Teachers who want to demonstrate gear ratios in class
• Anyone who wants to understand how torque is multiplied

📴 100% OFFLINE
Everything is calculated on your phone. No accounts, subscriptions, or ads. Your dashboard and progress are saved on your device.

🌍 Available in Spanish and English. Minimalist design with smooth animation, designed for portrait or landscape use.
