Anti-Backlash Compound Planetary Gearhead

This cutting-edge planetary gearhead is a revolutionary upgrade from my earlier Robot Actuator (smallest version): https://www.thingiverse.com/thing:3293562. Boasting about 50% more torque, significantly reduced backlash, and a silky-smooth operation, it's specifically designed for a 35mm tin can stepper. To ensure optimal performance, this gearhead requires 35 precisely-matched 4mm (or 5/32") balls for the integral slew bearing, along with a 38.4:1 reduction ratio. When printing tiny gears on even the most finely-tuned printers, minute irregularities inevitably arise and significantly amplify frictional forces. While increasing clearances in gear design can alleviate this issue, it often results in excessive backlash. My innovative solution is to engineer ring gears that flex radially but remain stiff torsionally. This clever design feature eliminates backlash while allowing the ring to adapt to tooth profile irregularities by expanding smoothly. Once I secure more time, I'll develop anti-backlash versions of my medium and large actuators, further revolutionizing robotic performance.
