Auto Tracking

Belt Technologies has developed a simple and effective pulley system for independently steering flat belts while allowing for easy on-the-fly tracking adjustments ( Independently Steerable Pulley ). The patented system provides a solution to tracking problems encountered as a result of operating environment changes and also eliminates downtime by allowing independent belt adjustments on a multi-pulley common shaft. Steering is accomplished by adjusting the angle of the pulley relative to the belt and modifying lateral tension. Rather than moving the pulley shaft through the use of pillow block adjustments, the ISP design fits a variable steering collar (with either a skewed or offset bore) and a sealed bearing assembly to the body of the pulley. When rotated, the collar changes the angle of the pulley body, resulting in the controlled bi-directional movement of the belt across the pulley face.
