Since it is a project for the university do so: draw a circle so that the thermal module is 1,1-1,2 times that related to the left ring.
do this so that by drawing the connection rays the circle is inscribed within the central area.it verifies that the thermal module of the outer ring is 1,1-1,2 times that of the central area.if it is not so add overmetal.
for the materozza then is another speech
 
So... the cynical materozzes are not cool but are very useful for example in your case!!! did you not make them?! but are you a mechanical or managerial student? because it seems quite important to me as an agony for a mechanical ing... If you didn't do it then it's a problem because how do we solve it?! an open sky would look good but in the central ring. . What you can't do because you made us the hole. the connection beams please put them, as long as they are reasonably big to the eye... r10 minimum better r15..

ps: are you sure it was not better to do it after this hole?! have you foreseen adequate courses of soul?
 
mechanical mechanic and of the cynical materozzes I have on a slide a figure and I have set to read the captions... .

However returning to our design, indeed to my :d, if I could freely choose I would have usilized a different profile and I would never dream of making a 13 cm gear by fusion..in the ground for more! the prof of has given precise dimensional constraints (those teeth must suffer 30 kw of power to 540 turns!!!! and we could not increase them!) , constructivi (fonderia on land, the max of luxury are souls). He also demanded teeth for fuction, but we took it by putting so many supermmetals that the teeth are drowned :d

As for the cynical materozzes if their use was findamental I wouldn't think about it 2 times to do a research in the library (in third year of engineering it has led to think that the internet is useless...). I would still be willing to put coolers in the central ring and straighten the outside
 
I'm sorry. but this doesn't work technologically! try to dimensional the matheality... according to me (I didn't do the calculations, eh) the base is bigger than the thickness of the outer ring (about 24 mm if not mistaken), so you can't put it! That's why I was so much more suited to the cyche. Also from the drawing I do not see the soul courses for the central hole... Where do you put your soul to make the hole during the casting? !
Now I am a simple second-year student who just finished the technology project including the study of fusion... I'm not an expert, but I think that's very imaginative. There are some things that don't come back... Do you have a contact person to ask? Maybe you missed something important. . .

ps: but how did you want your teeth to be made by fusion?!?! I don't see the height they have but judging by the image they seem very small... How do you expect them to come out of the merger?! :confused:
 
I don't understand what blindness needs in this case.
in practice the cynical materozzes are those materozzes that do not overlook the outside. they have the same exact function as standard materozzes, but there are some notices that atmospheric pressure no longer feeds the fuse.
I repeat: try as I told you and put a (standard) straightness on the outer ring!
the soul seems to be vertical so there is no need for soul flows because it is supported by the earth!
 
Okay if you put it vertically, it's true... Now I had a model in my head that I manipulated and I didn't think about it... But at least one reference, so as to leave a footprint in the earth... I would have done it!
boh, you have to try to make the calculations to dissect the materozze and see if it's with a support base of 24 mm... If you're on horseback! instead when it can't be done without the cynical materozzes are never a waste! especially if you make things easier because you have no particular constraints. . .
keep us informed about developments, I am curious to see how it proceeds:finger:
 
the teeth for fution and the central hole are we say technological challenges to increase the vote:d in any case we will rub them because they are too small even to sketch them. the problem of materozze calculation does not arise, because first I have to solve the fact that the central part has thermal module greater than the other 2....Do you have a table for the calculation of the coolers? ours is illegible
 
ah but then do you have the major module in the central ring? I understood in the outside... so it is a problem then because without changing anything you are forced to use the coolers, the materozza there is not... Unfortunately, I have no tables for their size. . .
 
Yes, but today I see with my colleagues if we can adapt the design to the design for casting, since that is not a functional part. However, yes, the higher thermal module is in the center, and that also agrees with what the heuvres circles tell me. now I look for tables and find a reasonable solution

Thank you for your help!
 
mah I'm not really understanding....it doesn't seem to me that the module in between is greater than the external one. If so just add overmetal to the outer ring.
teeth never and never go for foundry! . .
 
if you read the first topic I posted the data,

the area to present a thermal module of 9,6
zone b 11,2
the area c 8,4

this less than the connection rays that I don't know how to calculate (I guess I have teamed all the apigols)
 
Excuse me, eh. I see the left ring with a low thermal module, in the middle of an intermediate circle and outside I see a big circle.
What's wrong?? ? ?

Click to expand...
In fact! I also thought that the major module you had in the outer ring! the bigger circle seems to me right there... changes something in the drawing at this point, tries to bring you the highest module on the outer ring, the connection rays have no significant influence on the calculation of the module so you can also leave them. . .

ps: the area to is the central one where the hole is? and this area would have a module even lower than the outer ring? ! :eek:
you have not specified to what the letters to b c...
 
look at the first post for references, however the hi heuvres circles for how little reliable are still tell you that the circle in the middle of the central ring is smaller than those on the sides (i.e. in the outer rings)
 
The hole???? ! !but in the hole there goes the soul, what sense does the cooling module calculate? ? ? ! ! !
I continue to believe that who asked us the question is making confusion.solidification as you posted the design, symmetrically from the inner ring to the outer one!
I don't see any problems!
the internal ring module is certainly less than the external one.
with regard to the central area,as I said several times,just change the connection rays so that the thermal module (determined by the circle enrolled in this area) is intermediate to the two internal and external modules! !
:angry:
 
my question was how can I bring the central thermal module in an intermediate position? However thanks to all of the answers, we eventually used coolers in the central ring! ! !
 
but this without the connection rays! If you put the connection rays, it's no longer like that!
 
Sorry, but if you told me that the connection rays should not be calculated in the calculation of the thermal modules how can change the situation by putting them?
