Hi all. I'll make a linear vertical stage, carrying a load of 1 kg max. 0.4 metros of travel probably. This is for an application that would run several hours(10 aprox. ) for a couple of months. It's possible to find commercial lead screws, nuts and shaft couplers not so expensive, but i ask if a "normal"threaded rod with a "normal" nut could handle this(include the commercial (but inexpensive, $ 20 or so) lead screws and nuts you find over there). The thing is not be changing the screw and the nuts every week because of wear. The velocity could be variable, but maybe an average of 5mm/s, and some 2cm/s peak. Thanks for any answer.  |
