i was wondering what solonoid valves people use in axed robots? and how they make the ram with teeth built in (for poxwering the axe) and what sort of presure people use??? thanks...
a rack and pinion axe system is usually custom machined into the cylinder rod, i don't know of any rams that come as standard with teeth in
i didnt think so... but how do they make them air tight? and is there an alternitive to that method?
you could use an accelerator mechanism or mount the end of the ram to the axe arm. i dunno how they make them air tight, i have never made one
The rack on Hell's angel was cut out of the piston, and any rack like that is never totally air-tight. Tiny Hurtz has an off-the-shelf rack peice welded onto the end of the ram.
The seal in a normal commercial piston is wide enough to limit the losses over the rack to a minimum. It never slowed THz down, didn't it?
Hmm I think the rack and pinion idea is the best for axes, but sadly I don't have the obility to machine a ram with the teeth, and I was just wonderiing, what presure do people use for axes, because all the ones I have seen are low presure...
I believe there was only 1 FP axe in use the last years, Obsidian. But that was a fully custom job.
Oh ok, any peticular reason there neally all low presure? Is it to do with haveing the strength to convert the expansion of the ram to the rotation of the axe? Or is it just to do with the fact, it would just send the robot with the axe flying? And what presure do these robots actuly work at? 10bar? 20bar??? Thanks every one for there help so far!
For feathers it's in part the ease to find valves. Not many 5/2 or 5/3 FP pneumatic, affordable valves on this world.
And using 4 Burkerts to control the FP axe-system, ain't cheap, nor light.
