without knowing what use the tree in question will be, and how disassessment I think it's more like drawing.

Hi I'm Sunday, I'd never put two jokes on the same floor.

I'm sorry, but I don't understand the spacecraft question to record? ?
I don't find spacers recordable if not under laretifica in phase of assembly....so how can they record other elements... and especially what do you mean to record the bearings....what do you put them with the "tdk can" and you make them sing? ? ?
As for your design know that:
trees or pins in the assemblies do not dissect.
two fillets and two wreaths on the same side seem to me a waste of denari
the left bearing spacer I would make it a tree line (so as not to have a double reference as you have already been told and the left bearing I insert it from the left in this way I can use two similar type and size bearings.
At this point, I would resize the tree... .
good work to you and your fellow technical designers.

I think yes, in this way you can preload them, but I am not expert on this type of bearings and I hope not to say a chestnut.
However:
I would eliminate the wreath that blocks the wheel on the shaft and if the carving does not create problems of resistance to the shaft I would put a good seeger ring (under a wreath, avoid the threading of the piece, etc etc etc.).
I would bare the wheel on the tree by eliminating the spacer that leans on one side to the bearing and on one side to the wheel itself.
I associate myself with making the left space a joke directly on the tree.

I allowed myself to move here the discussion that is not expressly linked to solidworks but concerns more generally design and construction.
about the question:
from the posted design you can not give precise indications, lacks the placement of the tree in the axieme of the "machine". . how and where the bearings are housed, with what the shaft is coupled (I imagine there in between is a toothed wheel..), what and how it transmits etc. etc.
apart from that seen so do not precarious anything but go only to "seat" the inner rings (and as said in a questionable way).
in general, in addition to the "graphic form", it is worth saying a little by everyone. but in general, the design is little explanatory.

for the regulation of the precarious in the "straight" sense, no spacer is required. I want fine-step rectified needles equipped with locking system.
in general the spacers can be mounted (I mounted them several times) for reasons that go beyond the preload only.
For example, the outer surface of the spacer is often used as a working surface for a parail/parapolvere or to make grease-proof cases.
mounting two spacers, however, implies that they must be rectified on both sides and inside (and on the outside if there is a oil) and is generally an additional cost not negligible.

right, but even more flashing is the sampling...two separate elements, approached, with the same sampling makes the skin cling...

According to me, since you use the precarious glands the rulers with those, the small space ring I see it just sprang, mntre the big one could be useful for bearing support only on the inner ring. shavings with the ring you can do where you can not use wreaths. on bearing catalogues shows the correct arrangements and arrangements for ball bearing mounts

Thank you all for the answers you gave me, useful or not.
Premitting that the difference between a design design ed una bozza(that post was a bz to give the idea of our discussion)
I admit that some elements were missing to ask for your opinion.
I repeat the question.
Is it correct to use spacers to "preload" oblique bearings during assembly of the machine?
I attach a bz

how do spacers "preload" bearings? the precarious gives it to the wreath, at the limit the "limit" (if of the right measure).

mah! I have the impression that km6 is really useless, if you want to use the ring of space because you do not send it in line to the fixed part?
sampom

Forgive me,
but I'm dealing with bz I continue to argue that in that way nothing precarious; You got everything in line! tighten the wreath as much as you want (the little one on the right) but nothing happens, just snap the inner ring of the bearing from 25 without "reactions" on the slopes.
the central fixed part is bare on the shaft and the left spacer only holds the bearing from 40, so the larger inner ring is influential for the precarious, simply holds firm in axial position everything.
If you want to preload something the small right spacer should just remove it, so that by tightening the wreath on ø25 the inner ring is free to "run" and press, through the spheres, against the outer ring. the "axial reaction" on the shovel outer part would lead to press even against the ø40 to sx bearing, thus obtaining your preload on both bearings (but still not independently, and considering that they are of different size perhaps is not too correct).
But assemble in that way I have to tell you that I have never seen it.. or maybe I missed:biggrin:

Yes, if they are calibrated.
the same philosophy of conical rollers, the spacer must limit the preload.
if you use spacers you can lock the wreath without any special shortcomings, but the spacer must be calibrated well and coast.
no spacers need a lock with controlled load, possible, but unstable, in the sense that it must be constantly verified.
At the end, we use calibrated shavings in front of the spacer, so spend less on making the spacer "rock" and then put a set of calibrated shavings with different thicknesses to exchange.
The problem is what you need at the end, little noise? precision?
sampom
Guest
So, yeah.
but it would only go for the ø25 to the right.
to the left the spacer against the ø40 bearing does not serve at all if not to change the axial position of the bascula/shaft group regarding the central fixed part; It doesn't preload anything.

You belong to the jokes.
yes the spacer on the left serves, as it has also said sampom, to center the tilting part. the right one serves to insert a preload "Not" by screwing the 25-corner on the central part of the bearing.
we need precision.
