Abstract
A belt tensioner for a belt and pulley system is disclosed. The tensioner has a camming surface upon which a pulley axle rides, maintaining substantially uniform tension in the belt despite competing forces of the belt tension and a tensioner holding spring. The camming surface profile is generated, for example, when using a spring holding mechanism, by differentiating Hooke's Law.
