Hi,
Could anyone help me with setting this mechanism up? Slowly rotating partial gear drives spring loaded rack. When spring compressed, toothless portion of gear allows spring to quickly drive rack back to a stop. Gear eventuallyre-engages rack and cyclerepeats.
Can't use gear connection asgear is only partial. Tried cam connection (allow liftoff) between teethwhich does not seem to work (skips teeth). I could use custom motor on each, but this would not let me do dynamic analysis (to determine maximum rotation speed that allows rack to fully return before gear re-engagment).
Note: image below does not have rack and gear corectlytimed - but you get the idea.
Thanks for any input.
