Can someone give me advise of mounting this linear actuator. (I am pretty sure it is legal, but not 100% sure because of not knowing amperage it uses. Please advise me if not). I would like to mount it onto rev max tube for this design :
And have it attached to max tubing to make it easy to rotate. Here is a ruff cad model where the max tubing will have a bearing for 1/2 inch hex shaft to go into and the half inch hex to hopefully a linear actuator connected to more max tubing to make it easy if parts get broken to fix. Here is the step file.
Two things. First, there’s no specific amperage requirements–they just need to be downstream of a 20A breaker. Second, it’s marked on the motor–where the motor says “DC12V~5A” in the pictures, the “A” is the amperage.
That said, if you’re thinking of using this, I strongly suggest looking at the rate of travel, and the force required. 5mm/s ain’t gonna do you much good, and each actuator can PULL several FRC robots. I’d use the 900N if you can handle the extra length–10mm/s is better although still on the slow side.
And then the typical mounting for this sort of unit is a bracket, which is often included with the unit. Pin through bracket and base of actuator, repeat on the other end, mount bracket to whatever you’re trying to move.
This is likely to be a problem. Granted it will be faster not under load, but this is still pretty slow.
I see no off axis load ratings for these actuators, so using them at anything other than a 2 force member (push pull) is probably ill advised. Not saying it can’t be done, but they probably we not designed with that use case in mind.
You can likely achieve much of what you want to with a non parallel 4-bar linkage, you can get sime pretty complex motion paths out of them.
