animation rotation shaft

[fiz]

Good morning.

I am a self-taught inventor, so not very experienced. . .

I made a model of an alpha ironing engine so with 2 v pistons connected to a tree and I would like to create an animation that makes some spins to the tree, but I tried to search and I can only move it.. I can't understand why...

and the constraints are all right because "manually" outside the animation menu I can turn it perfectly. . .

Can anyone help me?

you have to give the tree angular bond of one face parallel to its axis with another face of another object (even with angle 0° type). then select that link from the browser, click dx and select "soul ties", in the window write the angle to "trace" (type 1 lap 360°, 2 turns 720°, etc...) and press play.

Now it works... thank you!
Can you tell me if there's a simple way to generate ball bearings?
