FRC1989 Compound Planetary Prototype about 30something to 1 target · 模型 256179
A compound planetary with a CIM motor on the input and a 1/2in hexshaft on the output target ratio is 30something to 1 for the planets 8x16x4 or 8x16x5 bearings needed (Hobby King) use 5/16 or M8 bolts as axles for the planets and Locknuts to fix them in place. This is a prototype in testing/development Print gears (sun,planets, rings) in a hard Nylin (Taulman 910, Hobby King CX12 or fiber reinforced) print the holders out of something that does not flex like ABS or HIPS etc. The rings are thin on purpose so you can force them over the planets (deform slightly during assembly the Ring holders are to be solid so to keep the rings from flexing after assembly. If you print with a .8 nozzle use 8 perimeters use 16 with a .4 keep layer height between 25 and 50 percent nozzle diameter
