in solidworks must draw a wormless conical (variable diameter) at height of the variable profile, where can I find tuturials?
Thank you.
Thank you.

hello titurbine, a life without end conical... I think there are no tutorials.
However you must start with known values of measurements, angles, thread profile etc.
draws a cylinder or cone representing the outer volume of the screw. draws on a sketch placed on one of the two cylindrical ends the spiral-made guide curve. on an orthogonal floor at the bottom draws the profile of the thread bread and eventually makes a sweep beam using the bread profile along the spiral.
the concept is equal to that of the realization of a classical thread iso 60°. change profile and the spiral will be conical instead of cylindrical...if needed.

in fact it was trying without being able to build a propeller on the cone through a loft with two different initial and final sections ( precisely conical) as I attach the file of the conical screw with variable height.

good day titurbine
I don't know if I understand what you have to do but maybe you could do that.
Let me know bye.

Can you send me the solidworks 2008 file?
Thank you.

You posted a group without parts! !

hello mechanics
actually should be a pack and go.
However place in stp, although in this way you lose futures.
I hope you see something.
As for the fact you do it in version 2008 I think I can not do it and for the fact the place as file stp

keep the concept good if it should be the right one, dimensions and profiles are random.

very interesting the image, just what I wanted.
now I check the stp file then I communicate you.

hi mecc..a want to be lazy is a bit the opposite to what you have invoiced....you have designed a "filetto" that has a giant step!!!more than a cut could draw the profile of the thread and swepparlo, obviously starting from the cone of appropriate size.

ok, however careful turbine that the 3d of flame control is more similar to a screw than to a dense rout.. .

no one spoke of toothed wheel. Where did you see him?
titurbina seems to want a sort of conical vine (at 3 principles if not mistaken) as seen from the pdf that posted; It should be just a water turbine, like peace.
One thing like that:
This is another method to achieve it. .titurbine, as you see you can do in different ways.
Unfortunately I am with 2010 and as it is arched it is not possible to save in previous versions.. you try and with a little imagination you will see that you can and it is not complicated.

mmmm feel, endless screw is by definition a toothed wheel... Am I wrong? Maybe. .
sampom
Guest
Yes, wrong..:smile:
simple example: the screws are endless screws; where do you see the analogy with a toothed wheel?
are screws to transmit (or to "self-transmit") the bike. ideally it could do so infinitely (and happens in coupling with a helical wheel for example.. perhaps from here your confusion), that is why the "without end".
screws trapeze, screws recirculation, screw mother.. etc., all vsf.
However from the messages and images there was no reference to the dentate wheels.
greetings

ok sam I know well, I understand what you mean, but if I as an initial message I read screw without end I immediately think of a toothed wheel..mit "endless screw" on google, look for images and look at the percentage of gears coming out..
I answered your question: where did you see the toothed wheel? and I answered you....citing a movie "words are importantiiii!!!":biggrin:

I bring back as soon as I get from wiki
"the coupling "screw without end-brown" aims to transfer motion and torque moment with high relationship between two non intersecting perpendicular axes. affect this relationship the inclination of the screw thread and the number of teeth (z) of the crown. the transmission of the movement is usually given by the screw (and is called "conductor") and this allows to maintain a static situation at the exit of the system. However, there are couplings where the screw and crown have an inclination of the thread and teeth (z) to allow reversibility. that is to say the possibility of having also the crown dented as "conductor", that is, able to transmit the movement to the screw. a disadvantage of this mechanism is that it has <0,5 , therefore for particular angles of propeller, the coupling could be irreversible, in poor words: "the wheel cannot move the screw." the performance is low because you have many creeps and therefore there is a high wear, and then the device should be adjusted over time.
