Sorry, I promised not to intervene, but...
you can't make drawings of details without making the asses first.... :eek:
It's forbidden!
not by norms, but by common sense!
how do you draw a detail without knowing how and where it should be mounted. and how do you then control it to see if the odds "baptize"?? ? ?
first you do the assist, even at the level of study, but complete.. .
then you do the details.. .
I want to know my idea. .schizzo complessivo.webpbut at this point I thought to eliminate the 2 seegers that are at the extremes of the tree and to put a needle with safety rosette so I eliminate the effect of carving and resists harder.. .

and maybe I put a space between pulley and bearing so elimino anke the third seeger (it touches me to stretch the tree though). .

I trust your considerations/corrections
Thank you!
 
and already something
from left bearing (h11 is a little too h6/h7 much better) and spacer ok
eye to how seziona a gear
shouldering ok (h11 completely superfluous goes well general tolerance)
cusicinetto is ok but what diameter will ever be the tree at that point could be 40 again but it is better to write it)
via the seeger insert a spacer or take a shoulder directly on the pulley
put the needles on the right and on the left can be a solution I do not think that in that position we need to eliminate the carvings much more useful to do it between support (seat) and load (grind /puleggia) outside they do not need much.
Since you have set up the quotas because they are indecent are good examples that have been attached to you.....
if then always as a sketch you want to insert the carcass with bearing housings and the rest of the project could be useful to you.
clean and smooth or dense?

I did not understand this last part:
carcass??? and what?? (I don't know technical language..I apologize)

As for the pulley I used a trapezoidal belt (I used 4) so it should be smooth right? ?
If I used a toothed belt the pulley would have been dented I think...

while I make a request:
I would need a catalog to choose unified wreaths or something..thanks again

Yeah, it's better.
And as long as you're there, you should also increase the space between bearing and pulley, because as it is now, you won't be able to make us stand the tightness mounted in the flange that holds the bearing in place in the carcass seat.
this unless you use a stagnated bearing to the outside, but it's a little "sleeky" solution that at most you see on cheap stuff, like various Chinese.

this door, as suggested also by bass band, to have to squirt, at least for top heads, also the part that supports the bearings.

As you can see, it is practically essential to think first of all, although at the level of a quick sketch, made on the "cheese card".

Excuse me.
within tip of feet
I read only the last post and only displayed the last attachment
I could say a few things.
I wonder.
it is not possible to reduce the hole of the pulley (big way is equal to the daa. of the bearing)
in order to create a beat shouldering
and a tree end cap to stop the pulley
that in fact should also be discharged around a hub
Thank you very much

carcass = "box" that contains and bears all the mechanism.
Do you want this to be suspended in the void? !
while I make a request:

online catalog of the site skf: irons and safety rosettes.
 
I'm sorry, I pulled up a quick and furious installation, just to explain. . .

Why don't you do that?
2 identical bearings
2 identical spacers
2 identical end rosettes
4 screws with rosette

no needle, no strange thread on the shaft, space in quantity for bearing sealing....

ok to uniform bearings and spacers, but for the head washers I am not convinced.
it costs less to make thread and quarry for the safety rosette than to make axial drilling of the shaft.
And the two washers with the holes you have to do them on purpose, while the wreaths and the rosettes are already beautiful that ready and in addition to you the "get behind" of surcharge.

Well, look, I was drawing ankio and my idea was that (excluding the 4 screws).
seeing the next comment I decided to put the wreaths with rosette.. .
design everything and then place....
so I can then think about the carcass (the hardest part x me because I never did it is what)

thank you all...I'm learning everything I've never studied at itis.I'm not really a model student! !
But I'm beginning to appreciate the technical design at last
I have a whole team of professionals instead of a master...:biggrin:
 
excellent advice, especially the design of mbt I would remove even the joke and replace it with a spacer ... but three equal spacers...so you can buy a rectified and chromed stem to trade without even having to return it, you mean the holes and the game is done.
for the carcass they have already told you is a metal structure in which basically the housings of the bearings are obtained and on which the blockings of the same are mounted (remembers external ring of the bearing well it must be locked axially)
for the rest also look at the first examples that if I remember these things well there are.
I see now the comment of mecbell and your answer the choice depends a lot on what you really need what you are drawing and also on machine tools and suppliers at your disposal. .. seen that for you all are unknown are valid both choices for the carcass we will see to help you but it begins to think that everything besides working must also be able to mount

Thank you.

for today I would say enough...anke because I am doing a "useless" job for school purposes because the relationship I have already delivered it with that [Bleep] design. .

Now and better than I concentrate on happie. . .
I'll continue tomorrow. . .
Thank you all for your help.
 
Good afternoon!
I'm back at work. .
First of all I thank all those who have spent precious time devoting it to a fanciful student who is trying to recover the lost time by attaching drawings explanations and everything that is coming back useful to me right now. .
Today I have delivered the report albeit the design is ca*re. . .
Let's say I've been forced. ..however I decided to fix it the same anke x learn something in anticipation of the exam that I will hold in less than 5 months.
I took into consideration the idea of the spacer you recommended.
being ignorant I need to know if the outer diameter of the spacer I insert between toothed wheel and bearing must coincide with that of the bearing.
There are also catalogues where I can choose the spacer I need or can I create one with a width of 16,5 mm? ?
on the web I have seen that spacers have prisoners who serve to block the spacer...I'm fucking blocking it? ? ?

I look forward to some advice... thank you
to respond to shiren sgomento that did not read the entire post...:cool:
 
:4404:
°^°
useless in the sense that for tomorrow I have to make a theme and since it's 5 hours that I'm doing I'm overall maybe and better I stay a little and continue tomorrow anke because I'm anke a tired hair.. .
we say that besides studying I would also like to live..:biggrin:
I still have my needs. ..ahahahahaha
I'll stop here.
:a
tomorrow..:mixed:
 
not to make the Cassandra.... I felt it, you might have noticed that I kept a little away.
 
I think the two seeger at the two ends of the tree can leave, there should not be stressed. . . .

even if I confess that I don't know between seeger and quarry, axial holes and vines, wreath and rosette what could cost more or less... I must inform:confused::frown:

Hello fulvio
max pendant
we have been young
It takes patience
to say the truth
I was beginning to see all attachments
the first drawings perhaps so dated years 60
It was a big deal like that.
Today is different
if you skip file transfer to cnc lathe
the quotation to give to a machine operator is wide different
I'm sorry except for sporadic examples
that in schools to address mecc the teaching has been delegated
to sw operators
the war with the Far East will be little complicated to win it
Thank you very much::smile:
 
seeger and quarry
absolute the cheapest and functional, at the end the cut is influential.
