Working Differential Model

thingiverse

I set out to create a differential model that showcases how it enables an axle to rotate at different speeds, and this open design facilitates my learning process by illustrating exactly how a differential works. When assembled together with printed components, the pinion shaft rotates, causing the ring gear to spin as well, which in turn rotates the output shafts connected to the wheels. If one output shaft is held stationary while the input shaft spins, the opposite shaft will still rotate freely. This model provides an excellent display of how a differential operates and why regular differentials are not suitable for off-roading or winter conditions. If one wheel is on ice and the other wheel is locked in place due to snow, all rotational velocity will be diverted to the wheel on ice. I hope you enjoy this model as much as I do - I put in a lot of effort learning CAD (solidworks) to bring it to life. If any tolerances don't work correctly, please leave a comment so I can address them. You know your printer better than I do, but I would still recommend printing the gears at 0.1mm layer height. None of these prints required supports. I wouldn't advise printing the stand in ABS unless you have it down to a science. Additionally, when printing the stand at higher layer heights, I suggest including supports so that the shaft holes print out nicely.
