Abstract

Disclosed is a steering roll tensioning method and device which provides for photoreceptor belt tensioning conicity correction. The steering roll tensioning device 1 comprises a yolk 2, a flat spring 3, a tension roller 4, and a pivot axis member 6. The flat spring 3 is attached to the yolk 2 at the center of the yolk and slidably with axis 10 situated in slots 11 at the extremities to provide the required travel length for tensioning. The device provides for belt tensioning and belt conicity correction in the perpendicular direction 7 indicted in the Figure. The device also provides for steering of the steering roller 5 about the pivot access 8. Advantages of this device and method include elimination of a clevis and pivot means. This configuration also eliminates the rocking motion that results from an offset pivot geometry, thus providing a true rotation about the axis of the belt steering roll assembly. The tensioning method eliminates additional tensioning or compression of the tensioning spring during belt removal, and is considerably simpler than devices currently in use.
