Belt and Pulley Assembly

It depends on how accurate you want your belt.



Create a new part to represent the belt.

Create a datum curve where you can vary the diameter of each end independently and vary the distance between centers.

Create a swept solid that references the curve in the cross-sectional shape of your belt.

Assemble your belt and change its dimensions to match the sprockets.



I wouldn't worry about the ribs in the timing belt. Its like threads on a bolt. But if this is your concern, create a datum point on the curve and pattern it along the curve. Then create a cut across the belt, referencing the point and curve only. Reference pattern the cut. If it won't reference pattern, you chose a static reference.
