Compound Planetary Gearbox · 模型 163189
This model is inspired by a Thingiverse model: https://www.thingiverse.com/thing:3233547 which I found to have some suspect elements, so I made my own design, using involute gears everywhere and ball bearings. It can be 3d printed with a minimum of support. This tutorial shows how to design gears from scratch: https://grabcad.com/tutorials/tutorial-how-to-model-involute-gears-in-solidworks-and-show-design-intent The required ball bearings are: - 2 pcs 8x22x7 mm - 6 pcs 6x13x3.5 mm - 1 pcs 25x37x7 mm - ~40 pcs 3 mm balls The gearing is approx. 1:30 and the gearbox can just about be back-driven (it is tight). Please be aware that the 3 planet gears are all put together differently in order for them to mesh correctly with the second ring gear. Please don't forget to 'Like'!
