Hello

Is freewheel assembly with degree of freedom possible?

under SoliWorks or proe 4

(is the real freewheel function feasible if so by which functions)

Thank you

Hello

You have to assemble the wheel with the pivot link and you will have the possibility to rotate it

 

EDIT: see image

On SolidWorks, I don't see how to make a real freewheel (only one direction of rotation).

 

On the other hand, it can easily be simulated via a "Motion Study" (animation) by alternating rotary motor and fixing (by various means) the shaft or the crown.

Hi @ GRANDOUILLER

YES it is possible

 

See these tutorials constraints

@Tomalam

The problem lies mainly in the fact of leaving the rotation free in one direction and driving a component in rotation in the other direction.

 

To my knowledge, this is not possible with SW.

We would have to see the inner workings of the freewheel to know if we can "constrain" it

Hello

 

A priori this is not possible with SolidWorks:

 

"There is no "one way" mate in SolidWorks.  If you want to show a sprag clutch in an animation you need to suppress and unsuppress the mate used to link the gear to the clutch shaft.  When you want the gear and clutch to rotate together, you unsuppress the mate, when the clutch rotates opposite, you suppress the mate."

 

So two configurations with the constraints removed or not will be the simplest solution!

Under solidworks, advanced constraints could work

@ Mathieu

that's what I said a few threads + top ................................................... but no one listened to ;-(

already well understood how freewheeling works

What type of freewheel?

Hello

 

Via the Solidworks motion study, you can add springs and detect interferences (the 2 bases of the freewheel): I tried on a basic model but the result is not as high as I expected.

There must be settings that I don't control enough for the movement obtained to be realistic.

 

But I think that a pro of the "movement study" module should be able to do it without too much difficulty.

I'm working on Creo and haven't found the same restriction functions for one-way rotation only

Thank you all
