radial bearings

[cacciatorino]

on the engine roller I forgot to change the pulley that will have an internal diameter equal to 16 mm so as to avoid striving on the axis.
for both reels I have instead hypothesized axial slide of 1 mm so in case of expansion there is 1 mm between the right and the segger for both reels.

But so the roller isn't guided if you don't put a seeger on the inside one side, which will certainly cause the two seegers to interfere with each other if you don't put a spacer.

If you don't know what you can use? But you don't answer me by saying 'read the catalogue!' tell me a bearing that can go well please. Thank you.

with that size there is little to choose from. . jumps directly to the rollers; with other constructive arrangements.

if you make full post with external cux you have much more freedom of choice, less constraints and definitely better ease of realization.

But so much. .

my drawing prof said, about the tables:

name, surname, and symmetry axis! :biggrin:

If you didn't put it clearly back to repeat the exam next time, rightly!

the axis at least there is (even if I don't draw point, but vabbè..). but the "bords" of the turned jokes just can't bear that they miss:biggrin:
if you have only that view in the workshop they will hang (and you make us look like a fool).

I tried to optimize a bit of jeff's work. Especially for the expansion factor that as he had made it he had not much sense and then why would he have to beat on the bearing after 1 mm? so everything fixed axially on one side and all free on the other, so if it stretches or the shaft or roller moves the bearing and on.

allego optimization with explanation.

However it is true, it has become a very "important" treatment. On the other hand we must also exchange ideas and we should always find the best solution, but slowly we learn, I hope:

... well I didn't think it was necessary to show you the table to be sent to production, I thought it was necessary to use a draft however I will take advantage of the holidays in relation to the basics of design:biggrin: so next time I will avoid many criticisms. Of course I'm joking!
See you soon.

Heheh jeff good....put yourself in the cool under a palm with drawing books in your hand that is good to go back every now and then. that you want to do, even in my pdf for example since swx dissects everything and does not take into account that the trees do not dissect ... or do some artifice or amen... as long as it is a scheme you understand the same.... idem x your:wink:

 

[Jeffcott]

Thanks mechanicalmg all in all but doubts have arisen, after the continuous interventions, for the engine roller.

 

[meccanicamg]

Please jeffcott, for the engine shaft, this is very similar to that of the crazy tree. However, you should consider if it is not the case of mounting a pair of bearings to reduce the bending of the belt's pull, as the 12 shaft is swinging.

the spacer that you put between the pulley and the left bearing does not need and on the right instead of leaving it 1 mm foul stuck with double seger. It is practically like my crazy tree but turned left with dx.

look that all this ambaradan costs a lot of work and I would say that it is not justified at all to mount the bearings within the roller. (that madman do it in many but that engine does not).

 

[sampom]

I'm going to have to deal with the basics of design so next time I'll avoid a lot of criticism. Of course I'm joking!

clear that everything is always said soundly and ironically, and the "critical" do not want to be that constructive:smile:

the fact is that between "technicians" certain things jump in the eyes, and even if I do only a hand sketch before expose it to the public ludibrio I make sure that at least respect the language used and known

It's good to go through every now and then. that you want to do, even in my pdf for example since swx dissects everything and does not take into account that the trees do not dissect ... or do some artifice or amen... as long as it is a scheme you understand the same.... idem x your

(ii) but congratulations on the work;

And you too, you fucking lines of the jokes on the turned trees, want to put them? costs so much?
with swx if you are together exclude parts that are not to be dissected, if in part you hide the sampling of the area and make the edges visible..ecco made your correct design; you set a perfect and precise "relation" and then fall into these "banks".
better a sketch on the cheese card rather.
here you must not prove anything, less the "knowing" and the abilities of each.. simple advice and help when possible.

and I don't get tired of repeating, simplicity, functionality, immediacy, avoiding any kind of calculation or elucubration, strange detections etc.
the expert eye of the operator looks to the flight the table and the piece is in the car..made! that are those quotas comma 5 on such lengths? What's that for? And we don't talk about the .25 and .75, that's Metro-controlled stuff.

last thing I stop::
can use a tondo ø14 even rectified h6???? there where "pairs" with the air and then to return it to the ends. Do you get them?

I can seem like an old rompicoxxioni, but I repeat that I do it ironically and above all constructively. I have more than some white hair

When do you start making some tricks?

What can I tell you? ! ? !
I'm here eating my liver, trembling for the alzaimer, reviewing the whole rack of the frogs, then biting my tongue and I say, "Come on, don't do that! they are young, they will be!"

But it's a superhuman effort!

Please, menagli tu, otherwise I'll hurt you!
:smile:

 

[meccanicamg]

hahahah boys... you're right, but I was in a hurry and I even wrote that there were no lines

I will try to use the cheese card next time I ahahahahahahahah but first I cheat it all

are so comfortable the pre-turned or rectified bars and in the end you can not have in stock all the material. instead the mythical bars in h6 there are always and almost all measures. Of course you can start from a thread to the good from 14 or 15 and turn only the ends but since to turn it you need to take the shot on both ends I would say that with a rectified and the sweet jaws I turn it right also with the parallel lathe. If instead I leave from a thread I have to turn it all back or work it between tips and have right tools and sinisters...so the rectified in h6 is justified.

placed here the file revised with the lines that you see correctly. :finger:

However both mine and jeffcott's design are not executive designs to send to the workshop so the odds are reported some without tolerance and without rounding. this is the design or engineering project, the executive will make it jeffcott and send it to the workshop. thanks for the appreciation of the work.

It's like the answer to the following question: with constant cutting speed if I head a tondo radially from the outside to the inside, what will be the speed at the center? answer: infinite. sin that no motor turns at infinite speed. Here... our designs are like this.:finger:

but are you sure of free bearing tolerances? usually to avoid lamination of the seats, the uncertain or forced coupling should be done on the ring with the rotating load, then anyway, a "something" that ensures that the bearing does not go out should be put.

Hi.

that the profession comes into play.
We're almost there, and eventually we'll figure out why it was better to use the version with the rotary shaft.

from what I understand, the need to mount the bearings inside the roller is born from aesthetic needs and differentiation from competition, it gives a shit if technically it is worse.

so much here you have time to lose..:smile:
Otherwise, normally, you know how many "motors would turn at speed infinity"?
other than mechanical paradox:biggrin:

[Jeffcott]

Forgive me for the stupid question but the heat today gives me to the head... I don't remember how tense the tape is!

every now and then I say something....:smile:

 

[Jeffcott]

I asked how much the cloth of the tape is drawn as I must determine how long this will have to be. I don't think it should be 1106.97 mm because it has to be tense cmq, right?

depends on the tape type and the best thing would be to ask the tape manufacturer himself. However in the first approximation it considers a primitive development "to vacuum" that is 0.5% less than what you will have once strained. the theoretical primitive development you have to approximate it to a finite value to the mm, or to the 5mm even better and then once to the assembly correct the inevitable tolerances of the development with the curtains that you definitely have prepared.

check (importable) that the roller diameter is compatible with the minimum winding radius allowed for your tape type.

where you think you put the motorization: Input or output roller?
