Sorry... maybe I didn't explain very well about the size for my application. .

This axis with double counter-rotating thread is a crazy thing :smile:!!!
but does it measure like an endless screw? ?

thank you so much for the sites you have recommended me on the scooters..ne I will definitely use :smile:

But why do you want to dimensional the tree? Don't you want to choose it in the catalog? I have no idea where to buy it, but I'm pretty sure it's on the market. You could try to hear these guys doing good stuff.www.igus.it
 
I remembered that years ago I had made winders with a mechanical translation device produced by andantex are devices with automatic reversal and adjustable feed step that are called uhing, in attachment you will find the catalog page

Thank you, but I can't open the annex.
 
So you convinced me that a solution with endless lives is better. . .
can therefore be something like that in figure but motorized?
only that I can't understand how I do, having a scooter of those x household appliances you have recommended, to make it supportive to the screw to turn it. . .

But if I bought me a pencil like this?
Can it be okay?
Any of you have any idea how much it can cost?

I would propose a biella/handle system or a glyph. in the figure at the beginning of the discussion (the black one) there will be nothing but a more or less modified biella crank. ...no lives, no lives with reversal or so sophisticated things:)

but haven't you seen that the last ones I posted to you about lat are already a fully integrated solution? the alberino/vitesenzafine is already "engraved" in the gearbox, you just need to fuck your "pinzetta" brings piece and mount everything in the loom/basation. Everything is in one hand.

And come on, other cinemas to build? we do the simple things and buy what is available and tested.

according to me you can do it just put two ends one up and one down tires to mechanical wheel command to continue the cycle automatically up and down;)

at the point they are much more comfortable, less bulky, without brackets and "camme", those completely tires "down of pressure" ( logical elements and); put them directly on the vents of the cylinder and drive the distribution valve.

However, depending on where the accuracy will be used, I find more comfortable and universal a completely electrical solution, with "home" power supply.
so that in all laboratories there should be a pneumatic system, however...
 
according to me the pneumatic solution generates vibrations at the ends of the race that destroy the coating...
electrical actuators are softer.
 
I don't have a great idea how a pneumatic cylinder goes, but if you tell me that it's feeling vibrations, as lightning said it can't go well otherwise the film is not very homogeneous. . .
