pro / mechanism - circular cam

[Bibbitaro]

Good morning, everyone.

I'm drawing a rotary machine.

in such machine is assembled a cam used to give a vertical lift to a spindle.

A rotational movement should be associated with a vertical one.

Now, in mechanism design I cannot make the cam work in question as the software does not recognize the path of cam lift (it recognizes it only if straight and not wrapped).
If I go to associate the surface of the cam follower with the surfaces of the cam, the bond fails.

I was wondering if any of you have any experience about it or have a technique to suggest.

on the site of the ptc there is something, but the procedure is to say little laborious.

Hello and thank you.

Fabrious.

smiths, the alternative is to give the spindle a motorbike law equal to what it would have if pushed by the cam. but I recommend the technique suggested by ptc, if you use graphs it is not so complicated.
Bye.
Frankish.

francè, do you know?

 

[Prof.]

Yes!! I'll attach the files to the circular cam, just change the charts in the two cams. There is also a video showing its operation.
Bye.

Good day, sir, I downloaded the circular cam, could you tell me the parameters to create the engines, so I can calculate the cinematism?
I have created a similar cam with the roller that has the same size as the throat on the cam, but physiologically on the worked piece, the roller stops. I would like to simulate in mechanism if the same thing occurs.

Thank you very much

 

[Prof.]

to create engines you have to go into applications > mechanism and define servomotors.
There is the special command.
Bye.

My question was related precisely to the values that I should insert during the creation of the servomotor (with the default values, when I launch the calculation of cinematism does not rotate anything) . putroppo is a little time that I do not use the mechanism, and I confess to having a little, indeed a lot of rust.

Thank you.

put a constant speed different from zero.
