Anti backlash nuts

[@ActiveAtom]

Great addition for an acme machine screw, it even looks nice brass aluminum and steel 3 great materials went into the making and the indicator after install does not lie nice makers fix.

[@capto8784]

Thank you ; )

[@leerogers6423]

Very neat work . Its ironic that you use this for the most up to date cnc equipment and that I am looking for a way to restore lathes that are over 100 years old. Aparticular advantage is that it can be made to fit discreetly on an old machine . Simple and effective . You said it and it should be the mantra for all design.

[@capto8784]

I really thank you! I have just adapted a project i had the chance to discover at work. I'm a operator on grinding machine (Studer etc)

[@ericjohnston6035]

Wouldent work on a lathe beacuse it would have to go to coil bind before it started cutting putting any accuracy out the window

[@750triton]

If you put some long set screws between the guide rods, you can adjust it by compressing the spring/s. This will remove the potential to wear the components. There must be some free play, minute backlash is necessary or parts will wear prematurely. You want oil to get between the threads, not squeezing the oil out

[@nourredinematoub6459]

c'est une bonne idée, mais le réglage sera délicat.

[@hikolanikola8775]

this doesnt work... when spring compresses you are back to back lash, there is alternative with screwsh with fixed tension witch actually works, but this doesnt work.

[@ctprjcstv3998]

I can watch this video thousands of times!! Nice

[@worthdoss8043]

I hate to be a wet rag but now you have spring loaded backlash. You are also causing constant pressure on the nuts causing them to wear faster. You need backlash/space to avoid this. Nice work though.

[@capto8784]

But is essential a constant pressure on the nuts! if I eliminate that I introduce a backlash! Thank you!

[@gordonjones1516]

Using either Delrin or Turcite X is a common way to alleviate the problem of introducing wear through the backlash nut.

[@vnderrr]

yeah I think if there is any real pressure on the cutter then the spring will just yield the same backlash. ineffective

[@ramonching7772]

FWIW... I believe the anti backlash nut should be a hard opposing flank to flank contact. Not spring loaded. A stiff spring is similar but becomes very bulky. Spring loaded nut might be the only way if the lead screw's lead variance is large. But then the screw should be junked in the first place.

[@mechmania8450]

Ok works with no resistance to movement but if there is resistance ie if you are milling the springs would be compressed.

[@EngineTuning]

... and this would create resonance with the spring rebounding, resulting in chatter.

[@allaboutengines5125]

it is the most useful video on the internet today... thankyou

[@tbrwy]

what do you call the silver piece that are screwed in first? collared screw?

[@rogerdeane3608]

Excellent remedy to back lash, thank you.

[@Autocentrante]

Thank you!😉

[@AdamPNelson]

nice. very educational. Thanks!

[@ScrapYardDog64]

Very good, thanks you gave me just what I needed..

[@donepearce]

Anti-backlash using springs doesn't work. Or rather it works when the axis is unloaded. Any machine will exert forces that will overcome the spring and defeat the anti-backlash effect.

[@Lesfac]

My gut tells me this will work unless some load overcomes the spring pressure.

[@michaelmarrs2322]

Very Nice Work!

[@capto8784]

Thank you!

[@AlbertAuWorkshop]

Anti backlash can not use spring, The blade also vibrates.

[@cnccnc2903]

Really awesome !

[@capto8784]

Thank you!

[@umargul5644]

Well done sir

[@onemischiefmaker7032]

Awesome!!!

[@TheJavaSync]

The right nut, it is not locked?

[@capto8784]

exact!

[@danielwang977]

Does this prevent backlash by converting the displacement into potential energy via the spring, such that no energy is lost? I'm kind of confused, can someone explain please?

[@capto8784]

The pressure of the spring on the second nut continuously eliminates the natural gap that exists between the screw and the nut. Sorry but it's difficult for me to explain in English concept so difficult.

[@nelunicoara4483]

How to choose the spring(s) to eliminate possible sliding along pins at maximum presure ?

[@djberg3483]

thats slick, nice work.

[@capto8784]

I'm happy you liked it! Thank you!

[@xXJosafat07Xx]

is that just a regular hardware store screw?

[@capto8784]

It is a standard screw!

[@jonathangofast559]

Non galvanized

[@josepablolopezaguado6191]

Great work!

[@capto8784]

Many thanks!

[@davemwangi05]

@@capto8784 you made it yourself?

[@capto8784]

Yes! ;-)

[@capto8784]

yes ;-)

[@mirager3873]

nice work

[@capto8784]

Thank you! :-)

[@vitterre9]

I initially tried the exact same thing for my hobby cnc but ended up doing some slight modifications. If your axis travel is really really short then this method is fine. For real cnc work though, meaning long axis travels back and forth, I noticed that the nut tends to decompress the spring so much that it eventually comes loose. I might be wrong but this is my experience so far. My solution was to design a spring compression limiter by confining the relative movement of the anti backlash nut to just a few millimeters. How I did it is rather difficult to explain in a comment, but after reading what I wrote it should be easy to get the idea of a possibile solution. Goodbye

[@markobog800]

Or just to use the ordinary machine screw with head to limit the second nut fall out

Warum nur dieses geklimper , Maschinengeräusche mag ich lieber aber sonst sehr gute Arbeit, Mfg. Horst

Funziona fino al carico delle molle, poi ...

[@capto8784]

Mah, io ho copiato un sistema che utilizza un nostro cliente su attrezzature professionali. Su quello che serviva a me ha fatto il suo lavoro. Poi test impegnativi non ne ho fatti

[@alexandercastilloaliaga6054]

ok sistem

Please rem ove the annoying music!

[@capto8784]

Please turn off the volume ;-)
