530:1 Planetary Reduction Gearbox for NEMA14 Stepper · 模型 279954
I needed a 200:1 reduction gearbox for a project and couldn't find one online, so I decided to try and design one. The end result was printed on a Creality CR10 at 0.06mm layer height in PLA. Much to my surprise, it actually works as designed. The final assembly is just 4mm longer than a standard NEMA 17x38mm stepper motor. Unfortunately my math was mistaken and this design actually produces a 4.8:1 reduction per stage so 530:1 for 4 stages. For my application that meant using 3 stages and a motor with 0.9 degree steps. That gives 110:1 and 0.008 degrees per step. Good enough for me.
