Free Robotics Gear Generator | Servo Motors, Stepper Drives & Actuators

Design custom high-torque gears for mobile robots, robot arms, pan-tilt gimbals, and combat robotics. GearDXF creates precision gears tailored to standard robotics actuators (NEMA steppers, RC servo splines, brushless motor shafts) with custom backlash compensation for 3D printed and CNC machined parts.

Key Features

• Tailored for NEMA 14/17/23 steppers, DC gearmotors, and robotics drive axles
• Custom backlash tolerances to prevent motor stall under friction or thermal load
• High reduction ratio multi-gear train design for robot arm joints
• Lightweight spoke cutouts to minimize payload weight and rotational inertia
• Export production DXF and SVG geometry for 3D printing, waterjet, and CNC routing
• 100% free with no commercial restrictions for competitive robotics teams

Frequently Asked Questions

How do I prevent 3D printed robot gears from stripping under high motor torque?

Increase the gear Module (use Module 1.5 to 2.5 for combat or drive wheels), increase face width (gear thickness), use 20% to 30% infill with 4-5 outer perimeters, and print with Nylon or PETG.

Can I design planetary gear reductions for robotic actuator joints?

Yes, GearDXF supports internal ring gears and planetary gear set layouts for high-torque, compact in-line robotic joint actuators.

Does GearDXF work for FIRST Robotics (FRC) and combat robotics (BattleBots)?

Yes! Teams frequently use GearDXF to design custom laser-cut Delrin and waterjet aluminum drive gears with exact shaft bores and keyways.
