Rotation around one axis (Mechanical) I am completely new to Blender and I have trouble solving a rather trivial problem.

I have a model of a machine which parts can only rotate around a given axis.

For example: Imagine a tank with its turret. The platform of the turret can only rotate in a circle around the y-axis (height axis). I wanted to archive this with a simple cylinder and a rotating plate on top.

I watched tutorials on rigging but using armature seemed the wrong move since it mainly bends instead of rotating the object. Is there a way to force the armature bone to only be able to rotate? If thats possible I could assign every part of the machine one bone with fixed axis rotation and a fixed offset to the next part of the machine.

Which technique should be used to archive the given task?
You can add a Copy Rotation constraint to them pointed to one Empty, then just rotate the empty on that axis by pressing R+Z.





Now when you rotate the empty all the other objects follow that rotation.
