Auto Tracking

Belt Technologies, Inc. has developed a simple and effective pulley system for independently steering flat belts while allowing for easy on-the-fly tracking adjustments (view here: Independently Steerable Pulley). This patented system solves tracking problems that result from changes in an operating environment; it also eliminates downtime by allowing independent belt adjustments on a common, multi-pulley 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 bidirectional movement of the belt across the pulley face.
