Ive just finished my 3D prototype for a visco machine (partially based on the machines found on this page ).




You can download the Model Here.
for those who cannot open DWF files, get a DWF viewer Here.


Does anyone that has experience with visco machines think this would work if i actually made it?
Its not designed with correct measurements, more of just a first draft.

Thanks

Very nice !
I'm not an expert on visco machines but this setup is problematic (i think i red something about it).
Several people had better performance with the "disk-on-disk" setup, meaning one disk on top of the other.

Hi leosedf,

Can you tell me how the two discs would be driven using that approach?
at the moment (as you can see from the model) im using two pulleys on the small disc (8 spools) and one pulley on the large disc(12 spools). The small pulley is driven by a drive belt thats interfaced with a motor, and the large pulley is driven by the second pulley of the small disc.

The small disc needs to be travelling in reverse of the large disc in the 'stacked' system, how is this achieved?

thanks very much.

You can see one example here http://pyroforum.nl/...topic=893&st=20
Blaf made a very nice machine.
Most of the guys who build machines like that had problems with the bP flowing freely on the funnel, that could be solved using a Vibration motor (from mobile phones, they do work perfect) attached to the tip of the funnel.
Samsung and LG phones (maybe some nokia's too) have button cell vibration motors and they can easily attached to the funnel.

Thanks mate,
Looking at blafs machine, I still dont understand how the second disc turns in the opposite direction!
Are both discs not turned by the same drive shaft?




thanks.

As for the vibrating motor, I have a few low voltage motors lying around that i can add an off center weight to, that should do nicely.

If you look at the drive belts to each disk closely you can see one crosses over its self, this would cause the disk to rotate in the opposite direction

[HerbertMunch]

Ah, i see.
thanks.
