CIRCLE

[lucatroiani]

hi to everyone, I ask for advice:
I have to connect a circular crown (it is copper, but it is not a matter of material) to 4 breeds (at 90° between them) that obviously converge on a hub.
I do not want to weld the races to the circular crown, because surely the deformations caused by the heat would make me miss the orthogonality between the plane of the circular crown and the axis of the hub.
Would you suggest me some motodo to draw this link?
Thank you. ♪

I imagine you know very well what procedure is necessary to weld copper... :mixed:

However, beyond that you would like a minimum of presentation to the first message, you cannot give an answer to your question.
for a simple reason. . .
there is no sufficient information!!!
What do those races have to do? transmit motion? How much?
What are the forces at stake?
What are the dimensions?
operating temperatures?
has special demands (exterior, conductivity, precision. . . )

otherwise it is like going to butcher shop and ask how to cook beef.. .

I pray, I'm a luca, I'm 30 years old, working at the comefri spa- magnano in riviera and I'm a production engineer.
I actually lack the information you ask me in my request.
those races, must support this circular copper crown that must be adherent (via other devices) to an iron disc. That's all. There is no movement to be transferred, no other effort on races than those due to the proper weight and weight of the copper crown. .
the greatest problem is precisely to ensure that the copper crown is perpendicular to the hub axis, which prevents me from welding to the tig.
Bye.

Ah, here... 4 steps from me...

already better.. Now we understand a little more!
size?

No, no, no...
the drama is that to weld the copper you have to heat the pieces to about 600°, otherwise the thermal conductivity of the copper vanifies the energy supply that you can give them by means of welding
you can limit the temperature to about 400° with special measures, but the concept is always that.. .

Anyway, talking about mechanical fixtures. . .
a vulgar team put on the sides of the race and fixing with screws (and heli-coil) the race to the crown?

Thanks for the advice, I finally managed to get out of the problem.
but did you work? near Magnano?
Hi.

Hi.

No, I work not far from hearing.
but I live not far from buja...

How did you solve the problem?

 

[lucatroiani]

a screw-to-head hole in the copper disc and a thread, matching, in the race.
at least it is fast running.

Hi.
