Hello, everyone, I'd need a hand. I should make a mounting of a rotating shaft on radial ball bearings with calettamento on conical shaft ends. Can someone help me figure out how to do this? Thank you in advance.

attach a clear design with all the necessary indications

I don't have a design. I have to start from scratch, or draw the assembly. what I reported above is the delivery of an exercise.

First of all what you can't do?
What are you studying behind you?
All you have is a description?

I'm an engineering student. I studied both the scholastics and the bearings, but in this case in particular I do not know how to move. Until now, I have had easier fittings, such as an ad or x generic assembly. now the doubts I have are about how to block the bearing near the conical tree end and therefore where there is also the hub (eg a pulley).
Yes, all I have is that description to realize the design

Then, you have a straight shaft, bearings, another tree with conical end.
You don't know how to lock the bearing on the shaft with conical ends.
That said we must assume that all this is suspended by air and that the rotazipone happens according to the principle of the buttered cat.
If that's all you have and you can give us, I'll tell you to put seeger.

from what I understood I only have a rotating tree with a conical end where I have to fuck a hub to convey the movement. But I don't know anything else, I think it's just the drawing to see the whole thing right. If I can find out more, I'll let you know. I'll try to do a sketch, and if I'm a coach,

beyond the seeger you can lock with nail and shoulder, spacers, washer and screw... all go well in the right configuration

when you have free time I would like to deepen with you the theme of this principle of motion, so I can write notes and share them.

you don't understand if:
- you have to use conical and non-cylindrical bearings and then go on a conical shaft on both sides
- if you have to mount two ball bearings on a cylindrical shaft and on one side it is conical....not in the area where to put bearings
in the first case take the wreaths and throws against the bearing that climbs on the cone and stops.
in the second case there are several ways: shouldering, seeger, spacers of various nature, wreaths etc.
these themes have been discussed several times on the forum.
It is impossible that you do not have a drawing text book with examples.
you also need to be interested and motivated... .

the site Skf has many explanations...google knows when everything...a research before would not be bad.

disappoint me.
is the first principle of physics.
since a cat if dropped will always land on the legs and that a stewed slice if dropped will always end on the part with jam, just tie a biscotted slice on the back of a cat and let it fall.
and here is the perpetual motion.

I connect to one of the many discussions about bearing mounts:
I have some doubts about a classic mounting with two radial ball bearings.
In this case the screw 7 will go to push the sleeve 2 until you get to the line. In this case, do you need spacer 8?
in the presence of the spacer 8 I am told that the seat that makes the joke could be deeper than the tree inserted.
I also have a doubt about the doubts: If there was no spacer 8 and the batutta was still deeper, it would go screw pushing the bearing ring, in this case it would be incorrect because it is radial bearings and can not suffer precarious of this type, correct?

Yes, because in the absence of space the two bearings would be free to flow axially towards the inside.
Yes, it should be, because by doing it deeper, the particular 2 would go to bat against the inner ring of the bearing and tightening the screw 7 would block axially the tree as the thrust would act against the package consisting of: internal ralla bearing right, spacer, internal ralla bearing left to discharge against the tree line; bearings would not be subject to axial preload.
in the exposed solution you have two jokes so you run the risk that you touch before that against the tree (battuta) and you would have an axial game of the latter compared to the sleeve.
if there was no spacer 8 and the bar was still deeper, tightening the screw the right bearing would move axially to the left, moving away from the external seeger and causing the axial game of the sleeve. There would still be no preload on the bearings.

Yes, I do. thanks to the clarifications

the locking of the two inner rings of the bearings, with spacer 8 through the screw 7 is correct and, with the shaft becomes a unique body.
However, I add that, taking into account the possible extension for heating, it is necessary to play axial game through the throats of the two elastic bands seeger.

here explains very well the theory of buttered cat
in this video explains very well the principle of cat buttered
