rototranslation wheel in Creo Mechanism

[sguercilena]

Hello,

I would like to turn the wheel on a plane, what kind of constraint I have to apply to wheel sufaces?

1 cam?

2 gear?

In my model applying cam constraint and servomotor, the wheel rotate but doesn't translate.

You should use a cam and make sure you provide a friction coefficient. You may need to turn on gravity if it will provide the load between the wheel and the flat surface.

Are you anticipating simulation output or do you just want to show the action of the mechanism?

Just for illustration purposes, I would put features in place to treat it as a rack and pinion.

This means the wheel device has to be on a slider type constraint ad the wheel can be a generic gear connection between the wheel device and the wheel at a specific ratio.  Now you can rotate the wheel with a Servo motor and the device should move linearly along whatever guide path you set up.

You could opt for letting the plane move on rotation of the wheel in the same way if you have the connections set up for a rotational to linear motion gear connection.  There are ways to lock views onto the moving object to mimic an alternate ground element.
