rack and pinion in Macedonia
 

Hello does anyone know where can I buy rack and pinion in Macedoni.

Story of my life!
 

It`s hard to find anything. Almost everything you need to buy on line, (of-course, if they ship to Macedonia).
Maybe, there are some small shops that I don`t know.
The only thing that I find is one person from Kumanovo, who probably got some Chinese things, steppers, drivers... He also got some racks and pinions.

you can send him an email.
Not so cheap, but that is all you got.

If you find anything please tell.

Ave!

You can contact LAGERTON from Niš , Serbia . they got metric module 1 rack and 20-30 tooth pinions

Thanks a lot for the help guys.

Danilo I contacted this firm and now I have bought rack modul 1 and pinion modul 1 20 teeth , thank you for your help.

I don't know your setup but if does not include some kind of reduction drive 20 tooth will be a bit rough, 3:1 reduction and 30 tooth pinion is what works for me

I am using direct driven stepper motor without reduction.

My mistake 20 tooth gives more precision than 30,
but without reduction ( 20 * PI ) / 200 steps = ~0.3mm positioning accuracy
no matter how much microsteps the drive has it can not position accurately in microstep.
Its no problem you can start without reduction and add it later if needed.

20 teeth pinion, module 1, metric, is a little bit small to drill out for 12mm shaft and then still get a locking screw in there. 24 teeth is usually okay.

I see your motors Veni have 14mm shaft just like mine, so watch out for that also as Gerald noted.

My 20 teeth belt reduction pulley had a 16mm collar so I welded another one over that so I can put a grub screw there. Was lucky to get an iron pulley not the aluminium one.

If you ever opt for belt reduction look here for those pulleys

Thanks Gerald thanks danilom, exactly this is the problem what I have now because I have not noticed that my motor shaft is bigger than inside diameter of pinion.

I measured the 30 tooth pinion and its 20mm, so I will have only 3mm for grub screw if mounted directly on the motor shaft.
