Connecting a threaded rod to a DC motor

[FlorianL]

Hello everyone,

What would be the 'best' way to connect a threaded rod to a DC motor? I am looking at efficiency, but also parts availability and cost.

The rod will rotate in a vertical position. The rod is a widely available one, 3/4" diameter and 10 TPI. Speed is not of the essence for my design although it would be nice. What I have right now is a tiny DC motor with what appears to be a worm gear at 10 TPI. That is not my only alternative however (in terms of motors) so please feel free to suggest something else if it improves in the area(s) of efficiency/reliability/availability/cost.

Any suggestions and ideas that you can provide me with would be most welcome. Many thanks!


Florian

I meant kind of what Don said, about fixing the screw top & bottom and minimizing the max length of the screw to your total travel.

If you don't want to machine anything then maybe try an electric actuator. Something like Part #2264K15 from

. Also you could look at using a lift table.
