Belt/chain and relativity violation?

Start with two pulleys and a belt/chain (Engage belt).


With one pulley twice the diameter of the other the smaller pulley should rotate twice for each revolution of the large pulley.


Now fix the large pulley or 'lock angle' and allow the axle of the small pulley to sweep a circle around the large pulley.  The small pulley's angle appears to remain associated with the large pulley, not the belt, and only completes one revolution in violation of the theory of relativity. Is this a bug?
