belt drives
Loop-powered mechanisms
Belt drives are mechanical systems that transfer power between rotating shafts using a flexible belt looped around pulleys.
Common in engines, industrial machinery, and bicycles, they offer quieter operation and simpler maintenance than chain or gear drives.
The old sewing machine used a belt drive from the foot pedal to the needle mechanism.
