oleodinamica pump

[PierArg]

hi, the technical name for the two trees is conductor and led.

Now I don't know if your prof cares but the thread doesn't draw. there is the thread command where you only check the parameters (for example m12x1.5 just to say randomly). When you put it on the table and put it on the table, the cad will remember the parameter and will exit m12x1.5.

If you want to draw it you have to create a helicoid that acts as a trajectory and a triagolar profile that follows it.

 

[PierArg]

If I'm not mistaken, there should be the "molla" command or something. no need to go into the surface design.

Anyway, I would do it in one piece. the choice to make it in different pieces is used by the builders of the pump because at the varying length of the toothed band also varies the displacement of the pump. Moreover, another reason why you make multiple pieces is that the terminal is not always conical but can be cylindrical, grooved, pen, etc.

I would opt for the choice of the single piece.

 

[Aranciameccanica]

but how do I do it in one piece? Can I join him now?

 

[PierArg]

It's a bit of time I don't use cat anymore so I don't remember if you can do what you told me.

simply make a profile revolution taking into account the conicity and diameter of the stem. then, placing you on the shaving plane make an extrusion of the tooth profile as long as the whole band. It's just two features, and you're getting it all right.

ok thanks!:finger: very kind... I ask you one last thing... where can I find the standardized components that are part of the overall I am drawing? ...is there any catechism blocks?

 

[PierArg]

if by standardized components you mean screws, nuts, tab, seal ring, seeger, etc., you can find them on traceparts.com.

I hope someone else gives you other sites because I don't remember them.

should be in iges format

Please.

rest available for further clarification

Bye to all,
I'm drawing one of the two trees in the pump (technical name? )

I almost completed the design, it is missing only to realize the threaded tang at one of the ends

How can I do that?

I had thought of creating a propeller (in the wireframe and surface design section) and using it as director for extrusion of the thread profile(in the part design section). Can it work? Is there a simpler way?

how do I combine the various pieces that make up this tree? were all created in the same catpart

the easiest way is... that you do not model threads :biggrin:.
it does not serve anything, except to unnecessarily weigh the file, lengthen the time of regeneration and "straload" ram and hardware. and above all losing time (which in work is the most important thing).
it is used to put cosmetic thread, a simple display that gives the impression of the thread; so:certainly there is a command like that.
that then as said, at the table is recognized and annotated correctly.

if you just want to try to "cut" into the solid a thread (but just for educational purposes, to learn the various features of the software..), then yes, the method is approximately what you imagined. make a cut sweep following a helical path.

mica vero esiste anche in think3...ciao

 

[PierArg]

Good morning.

I also confirm that inventor has it. try to see on the command "filettatura"

 

[ferrezio]

also because from personal experience, where it is necessary to see the thread I always had to shape it.

Hi.

 

[stef_design]

the reason why catia does not have the "visual" thread is only because it is a serious cad. if you need to see the models (as suggested by ferrezio)

It is not called "visual" but cosmetic:biggrin:

Good boy!
so you lose time (who knows why "in the ancient" mechanical design has unified according to the thread made by 2 simple lines.. you could do all the triangles and join them with the curvilinee:biggrin and "kill" the pc.

I am allowed to answer also for stef... and I ask you:
you have ever tried to shape a bottle of water, then try to tell the molder, "look I drew the cosmetic thread on the model".

When I said that I had to draw a thread I certainly did not mean the metric thread of a tree codlus (for that there is the representation that from the one in the table), but I referred to the filets that were to be born, for example, in the plastic molding process.

I'm closing here because I don't want to get out of the forum.

thanks, you did well:finger:

 

[Aranciameccanica]

it is true that modeling the thread takes away some time and weights the design, but I thought to do it for teaching purposes. . .

regarding unified elements( rosettes, elastic rings, etc.) are already beautiful and ready models not paid on the web?:biggrin:

thank you for all the answers, I hope one day to be of help

Hi.

I do not make moulds but mechanical "gratitude and simple":smile:
and of course I was referring, as in this case, to unified metric threads. . I could also not put cosmetics so much the model I see only me, in the workshop go the prints paper of the 2d boards (except when I turn to external suppliers equipped with cam. but always unified stuff so just the note).
but on the contrary, I always put the same (velociously and "lightly") precisely because on the table (which is what I care about) the correctly unified and parametric annotation replies. so you don't have to add anything "hand" in drawing.
obvious that the "special forms" (and threads of bottlenecks such are) the pattern as well I. but the bottle is one with only one "filetto"; imagine the large set of a plant including all services (but also only a single part variedly worked) how many thousands of different fillets can have. you will understand that speed of execution and lightness of management assume a very important role.

all clearly without controversy.

greetings
Marco:smile:

p.s. for a student, at a didactic level, it is good to learn to "dominate" completely the tool. so well a couple of threads modeled for benign, also because they can help to understand the type of processing, considering that a university maybe a workshop will never see it.
but when you are at work (and as mentioned above depends on the work you will do) forget it! Who pays you whole days to sweep and helids? :biggrin:

 

[Aranciameccanica]

hello orange needs your help again. .
ideas to achieve this particular?? ? :smile:

 

[Aranciameccanica]

Hello, everyone!
I don't know why you didn't answer my last post, but it's okay.

I arrived almost at the end of my project. .. little: the animation of the pump (I don't know if it is possible ) and the application of the materials. . .
I found some problems with the materials:

after assembling body, shaving and the two transmission trees, I set myself the goal of applying to the body pump a transparent material in order to show the two internal trees. . .
I created an ex novo material, and I applied it to the pump body...but its appearance does not change in overall...the new aspect I can see only in the catpart of the pump body. .
I hope you can help me
