kysan gearbox nema 17 3d models

With split sun gears (one idler), un-synchronized rings and meshed planet gears, the goal is to achieve a reduction/torque increase sufficient to drive a 130mm (2.2") R/C wheel from a NEMA 17 stepper up-to about 60 rpm. Many thanks to...

I made this gearbox for a robotic arm i never ended up making, the gearboxes are more or less fine but struggled on high loads.you will also need 3 bearings whioch are 3mm ID, 10mm OD, and 4mm thickness/width.(optional) 3 .5mm metal spacers can be...

minimized model, with appropriate mass

Suitable for 3D printing with few supports.Use of ball bearings to make the rotations between the various couplings smoother.

I made a video showing the assembly and comparing FDM and resin prints of this model: The video also has a list of required hardware in the description.

Made this to avoid using bearings and used extra fat teeth to avoid gear slippage from PLA stripping easily under stress. ... Designed for this motor: https://www.amazon.com/dp/B00PNEQKC0 Motor Model: 17HS19-2004S1

I swap out the sun gear to fit a 1/8 inch nut, and it functions nearly flawlessly, but sits a tad too high. Everything else remains identical. ...A side note is that you could also substitute an M5 bolt for the output shaft, using a small amount of...
