In those designs, I've always been concerned that the moving part of the gear rubs against the outside lobes. This repair video shows a Sumitomo Cyclo which uses rolling pins on the outside, so minimal friction... https://youtu.be/H_oMVO_OTGs?t=157 (There's another video out there that shows an exploded view of this, but I couldn't find it). I used this idea for some 3d printed hypocycloidal gearboxes for a robot arm, using bearings for the outside pins. It works, but the plastic is a bit squishy - on the TODO list is to cnc machine them out of aluminium, which shouldn't be hard as they are 2 1/2D parts. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
