radial bearings

[cacciatorino]

I say better, after you chose the bearing for example skf 61901-2rs1 where you see that tolerance you have to give?

on the catalog skf.

south catalogo skf.

..maybe the voice tolerances..?

...from the internet the link is:http://www.skf.com/skf/productcatal...wer.jsp?tablename=1_0_t26&maincatalogue=1〈=itIf you have the catalogue 'the desired bearings' printed in 2008, just go to page 158 :finger: it's all very clear.

if you have the catalogue 'the desired bearings' printed in 2008, just go on page 158

I have one of '89 and I am on page 71..:biggrin:
but in all catalogues there is a convenient index. .

I understand I go to see there but can you now tell me what changes in the calculations if you put the pulley on one side of the crazy roller?

 

[Jeffcott]

I attach a photo of a weigher already made but I remind you that the substantial variation (for now only study object) is in bearings, within the rollers.

 

[atofras]

mechanical excuse tell me what to do in calculations if you put the pulley on one side of the crazy roller? I saw the file you put on the forum but I don't know how to do if there's the load of the pulley, maybe if you put the difference with the one before I understand more

Here we go. but my question I'm asking myself, as almost everyone is: why complicate life by putting the bearings in the tree instead of traditional? Actually, you don't earn anything like machine tooling or bulking. and there is a low structural rigidity because the bearings are small. But the charm of the different... not to copy applications from competition etc. ... good jeff. I also do so.

If you put the pulley on the crazy roller, it becomes the motor roller with pulley conducted.
you will have near the center pulleys the pull force of the belt to be applied on the tree. then you will have the isostatic tree as in my notes of the exercise and you will have a second force, right or left, near the bond.
the equations of the static (first point) are recalculated. :finger:

..indeed, lost and raised costs. .

[atofras]

but can you also put the bearing inside the pulley?

 

[Jeffcott]

...the charm of the different ... not to copy existing applications etc... really mechanicalmg do that? I thought it was a joke, at least don't tell me you put the bearings in the pulleys. how will it be (but what name is it?). I want to point out that you're joking!

Bye. :smile:

Yeah, sure. we put a pulley so much so that you make "two laps" on the roller on Saturday afternoon.:biggrin:

atofras, the pulley has to drag the roller in rotation. we said that it will be calettata, so fixed, on it; what does a bearing stick there?

And forgive the jokes. .

greetings
Marco:smile:

p.s. Of course you're joking. What is the world? :biggrin:

...the charm of the different...

and the charm of the "different" keep it for you..:tongue::biggrin:

 

[meccanicamg]

jeffcott we say that often and willingly you want to achieve something but not with the idea that you get "set". So we think about it and we find a different solution, by faith, by conviction, we make calculations and checks.

It is true that there is little to invent today especially on these things, but if there are different schools of thought there will be a reason...no?

but it is not the charm of the different in that sense....mannaggia...oh but that evil:wink::tongue: fortunately I am the malicious....:biggrin:

 

[atofras]

I got used to the jokes: cmq I said a bearing on one side of the roller and the second (on the opposite side) inside the pulley

If we put the bearing in the pulley? calculating friction between spheres and slopes, at what speed should the pulley itself go to imprint on the shaft the torque stability?

Who knows I'm serious about this?

and then smile::smile: what is that angry face?

I imagine he thought he would fix it "in the head" to the roller, as extension of the roller itself.. doing "unique body" the cux "may" also be put in that area.
Trying to interpret. .
