helical toothed wheel

[Half65]

hi to all, I have this wrecked helical wheel destroyed that is of a period tritacarne of which there is no spare so I would like to recreate it first printing it in 3d then once I am sure I make the mold and I pour the resin.
I never did and looking for both here and in youtube etc I found nothing for the creo but only pe ril solidworks.
is it not that someone has already done such a prt and would turn it so I only change the measures? I have to go for attempts to get the measurements on this sample very hard.
Thank you.

this first view, shows a fairly clear picture of the toothed wheel, there is the number of teeth and you can measure the outer diameter and also the interior.
Bearing in mind that the primitive diameter is not half between the two, but considerably more on the outside, one can assume its size, which divided by the number of teeth, gives the module.
the module is rounded between the possible, multiplied by z (number of teeth) and the final and certain primitive diameter is found, then the outer diameter and the inside.
It is almost certainly an endless screw reducer, you have to recover the latter to measure its diameters and calculate its entirex if it is not possible to detect it from the box.
This data will also give you the inclination of the screw propeller and, therefore, of the helical wheel.

I'd say some science takes us.
We can also help you if you give us information.
first you need to calculate the values example number of teeth, external diameter, interasses with coupled wheel, coupled teeth number. Can we both do it?

I suggest you use freecad with the fcgear module so you get what you want. If you want to go to attempts you can use khk gear and try the various options...but if you don't know what the parameters of the dentate wheels are....let it be a professional or first look at a little theory. speech made many times on the forum .. look.

Also tutorials on youtube are good for any cad, just fit them.

here is a part for toothed wheel to helical teeth.
It's a model I've twisted and adapted to my needs.

Thank you very much, that's what I needed but unfortunately it doesn't open. I have seen that it is made with cere 6 and I have the 7 so there should be no problem but I see only the icon and that it weighs 1,84mb but enough, it does not open with anything, not even with creo view.

I spice, but the last rescues were made on creo 8.

That's why it didn't open. .

I do the upgrade that's a lot I don't do, recommend me 8, 9 or 10 you?

 

[AlbeLav]

I stayed at 8.
I think I'll do it in a few months.

we do not have windchill, if not erro are additional packages to pay aside for standardizations we do not need so given the product we do and already costs us a bang with 2 creo more maintenances.

I put the 9, with the 10 I know I have to change pc because after 2 failed attempts I gave up but I managed to open it!!! Now I have to change it if I can; mine has only 12 teeth and ø28 external with thickness height 28... Thank you very much!

absurd, I can't even change a share, it looks like everything's stuck

 

[AlbeLav]

geometries are all guided by parameters.
enter to change parameters, you will see that you change geometry

 

[AlbeLav]

I noticed some mistakes... .
That's what you need. Adjust the angle of the propeller.

Hi, I can't see the zips that came to you, you can confirm this data of your toothed wheel: z 12 - module 2 - external diameter 28 - primitive diameter 24 - internal diameter 19,3 ? or are different.

you are a myth!!!! Thank you.

Unfortunately rotten is really bad and I can't take the measures, I'm going for attempts by printing it in 3d and trying it and then changing it because it's the only way to reset the measurements. Then I will pass to a resin mold.

 

[Marco F inox]

Take the measures I gave you, I'm sure they're right and don't waste time in unnecessary attempts.
