exercise - drawing of machines (reducer)

[xxi]

in the output shaft I can put up,a cylindrical roller bearing
low, another cylindrical roller and a double effect brace
Can it be a right solution?
Thanks again

Do you feel right about this?
Is the case closed? :smile:

feasible, just use the appropriate and properly bound roller bearings.

But the cylindrical ones aren't good? ?
I stuck them in the four corners so they don't disassemble

they can go well but must be bound differently.

It is important that you do not become rigid all the tree system and spacers and wheels because if you dilate you preload the ball bearings axially if not duly left free axially.

everything is fine, just know how to fit them correctly.

"locked in the 4 corners" the bearing has the jokes on the outer ring and on the inner ring on both sides. You have to see the type of bearing you have meso. If it is a nj or nup it is not good. if it is no or no yes.

then nj nup I have to mount them like free ball ones in the outer or inner ring, and n as I have assembled them now.
correct?

You answered yourself. for bearings if you look well on the skf site there are a lot of sketches of how to mount cuscientti depending on the types...just look for :finger:

in the skf all kinds of these bearings (cylindrical rollers) mounts them blocking them in the four corners! !
How is that possible?

it shows them all blocked because the type n and nu uses them as trolleys and nup nu+hj and nj+hj uses them as hinges. He never uses a bucket as a cart!

Mechanicalmg red lines should be the ones I see behind, deep down,
Do I have to do this?

This time I printed it so... even if it sucks... and I marked you the corrections:biggrin:

in this reducer one of the ball bearings in the exit shaft must be locked in 4 points and the other free axially. Right?
so it is mounted wrong! !

No! otherwise preloads axially. What did you put to do the double-sided brace otherwise?? ? That takes away the axial thrust. The other two only radials work!

On the first page you answer me I didn't mention you!

I don't know if you can figure out how I drew the case.
(cylindrical rollers nu)

Red lines exist. but the roller bearing is badly put that close to the double brace. How do you put the bearing in the hub? prestigious game?

if there are the edges go the lines, if there are no edges no lines. What's the question? There is something that is not right in that design...you don't understand where there is a case and where there is the other and there are lines that should not be there.

to mount that bearing is mounted in the tree and then everything is dropped in the box from above.I don't understand what you mean?
If you have time and want to make a correction, I thank you so much.
I'm breaking your balls.

all those things fall axially. It's always the same story. you think that's half a gearbox and that there's the other half on it. But I don't think that's the plan of division. However, not knowing what the plan of division is because sti gearboxes never teach them in full, I would say that the crates should be sampled (all except trees and bearings). and all the mechanical organs are soaring not to come down from above!

if it were really half case, the fixing holes and the reference plugs are missing. and however the design must be fixed.

I ask the question: You can draw it like a decent rotary seal on a serious lid? :biggrin:

I marked you a pair of white lines that you cancel... Then the rest decide what to do.

you are all the reason of the world but the prof told me that for the main case we cast stu kale of exit tree from above, the case is open divided in half (it has no holes but I have to put them). the input shaft is preassembled and inserted axially.
you will have more experience in the field of work, but so the prof told me to do.

You show me your reducer like mine, but how do you say? ?
And show me some cool lids? the prof me always draws them so:smile:

ps: If all trees are mounted axially, are they easier to disassemble for maintenance? !

follow This is what discussion that we did a long time ago. find all explanations.

How do you think you get them coeprchi? printed? back? What do you put for the seals? look on the website skf and on the book!!

If the tree is axially preassembled, I would say that the diameters are not divided into two shells, so they are made in one half case.

If the case is split as your (as you divide the steam turbine cases) you have that the bearing housing half in one case and half in the other. there are different issues and different prescriptions to bind everything.

then if it has fallen from above it should not be sampled if it does not pass the section.

Why have you marked me the white lines, are those of the hole or not? look I did so in the other design

but let me understand better you can fall from above blessed trees already mounted yes or no?
