Gearbox v4 ideas
anticitizn opened this issue · comments
- Make gearheads as short as possible (the current size is somewhat arbitrary and they are plenty strong anyway, 5mm gearhead height per stage should be attainable)
- Merge bottom cap and S1 Ring (4 less nuts and screws needed, as well as removes need for taper on S1 ring teeth)
- Add slightly more distance between S2 Ring ceiling and planets to remove friction when under vertical load
- Add ridges on the contact area between S2 Ring and bearing to better distribute glue
- Make planets hollow (save weight and printing time, likely at no significant cost in terms of rigidity)
- Reduce space wasted due to the bearing somehow? (not necessary but printing time reductions are welcome)
- Reduce height of S2 Ring bearing outcrop
- Add holes under bearing in S1 Ring to enable prying the whole bearing-S2 Ring assembly out with a tool (friction from all the gearheads might make this impossible but worth a try)
- Outcropping 'cylinders' on S1 Ring with thermal inserts as attachment points
- Reduce amount of output nuts to three? (saves weight cuz less screws and can also shrink S2 Ring volume a bit)
~30% reduction in print time expected (~5 hours total)
