How do I model a drive belt between two pulleys?

I'd use the sweep command with with belt profile and the path your belt will take. This will give a solid model representation of the belt.

In the assembly you can not have motion on your belt, however if you have two pulley's with revolute mate's and connected them with the gear relation and correct ratio's, this will enable a drive train to work as if a belt was driving. The belt could be droped in for representation only.

In the same plane as the sides of the pulleys draw a sketch line representing the outer path of the belt (use the circles from the outer diameter of both pulleys with tangent lines).
Next in the cross-section plane of the belt, draw the belt profile (this could be pulled from the belt profile of the pulley).
Finally, simply sweep the belt profile along the sketch line you drew first.
If you draw the pulleys first, and then the belt, any changes you make later to pulley diameter and spacing will update in the belt size if you use the right constraints when sketching.5
