> Harmonic and cycloidic reduction drives are to slow > 6:1 or 10:1 should work.
My first robot arm used 9:1 3d printed cycloidal gear boxed (plus 3:1 motor to gearbox pulley reduction). Cyclodial ratios can be made small with less teeth/lobes and larger pins. I'm not sure if that makes them any stronger, or more efficient. At the end of this video is a graph that shows how various parameters effects cycloid design - https://youtu.be/CJyCcXob0c8?t=49 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
