Building my mill...

[Ox]

I remember studying about those gearboxes and I would love to have a few but have never even seen one in real life.  They are also to rich for my blood and I can't afford them.
Weren't you able to find at least one in the junkyard?
Do you ever find more?
Where is a good place to find them?  Were they used on a certain type of machinery more than others?

You can buy them on E-bay.

I cleaned out a few textile factory's. I got 88 Zero-maxes and 9 Uling drives.
I got 100's of motors and gearboxes of all kinds and many DC drives.
I wish I had some newer PLC's and VFD's The Uling drive is another unique
working piece of technology. I also got a lot of Zero-max linear actuators
They are threadless, mechanical, screw-type devices designed to convert
rotary motion into precise linear motion and thrust using rolling element
ball bearings but I haven't found a use for them yet. Maybe I need to put
them on E-bay. I also got some 3 phase PM motors with single phase drivers.
Nothing like I ever seen before. I found that if I chuck one up in my lathe
and spin it and directly wire it up to a second motor it will turn one to one.
I'm building a 3 point bank mower and I'm going to put one of those motors
on my PTO of my tractor and the second one one my mowing deck. I will
have a 3 phase bank mowing machine. Motors are rated at 3HP.
I could talk about all my junk for days.

I like hearing about the capabilities of junk, cause I don't know myself and it is hard to go junking if you don't know what to look for and what you find will do for you.
Thanks

One of my favorite past times is junking. If I find something that I don't
know what it is then I buy it and take it home to research it and take it
apart to find out how it works. Hands on learning. It's the best way.

          Hands on learning, been doing it since I was in diapers! Still take lots of thing apart to see how they can be repurposed. Sounds like your linear actuators can be put to good use.

Our junkyards are junk compared to yours. I couldn't get a rusted out wheelbarrow with a flat tire around here.

I think most junkyards are like that. You got to hit them almost every
day to find the good stuff and you gotta find it before the next junkie
gets to it and then you got to take the time to unbolt or cut off what
you need. On top of all that you need to be very good friends with the
owner or your not going to get anything. It really helps to take sodas
in on a hot day and hand them out to the workers. In return they will
save thing out for you so they don't get cut up. The yard I go to everything
gets cut within a few hours after it come in.

I'm working one one of two face-plates for the lathe.
This is 12" X 1" solid steel.



 

[JRWoodchuck]

I really enjoy following your creativity!

[Kbeitz]

Hey.... Thanks... That's what this forum is all about...

I got the fist one done. Now to start on the second one.
Anyone have any hard 4" x 1/2" lag bolts for sale?
I need around 10.



 

[Kbeitz]

I put it back in the lathe and put some alignment circles on it.



 

[Kbeitz]

Finishing up the second one.



 

[Peter Drouin]

Looking good, 8)

[Kbeitz]

A little more work today...



 



 



 

[Kbeitz]

I found a better picture of what I'm trying to do.
I hope to cut some cants that will look like this.



 

[Peter Drouin]

That will work if the feed and rotation is timed right. And will look cool.

[Kbeitz]

The timing will be done with a Zero-max. That takes all the work out of it.

[plowboyswr]

  ;D

[Ox]

Do the zeromaxs have a click stop throw or infinite like hydrostatic?

[Kbeitz]

Working on the tail stock today.



 

[Ljohnsaw]

Huh? ? ?  I think I understand.  So with enough clutches, it will be a smooth linear movement - no pulsing?  These drives are one direction only, correct?  What happens when you reverse the direction on you head (assuming that is what is driving the zeromax)?  I guess you will have to disengage the drive and set the new side to cut in your pattern?

[Kbeitz]

Drive the input either direction will turn the output only in one direction.
You can buy different Zero-max's with reverse but I never seem one.
You get very smooth linear movement because one clutch engages before
the last one disengages. I will disengage the drive at the end of each cut.

Here is a video showing the inside of one.

Here is a better video showing you how one works.

A lot of cutting and welding today.
