A disk screen or like shaft structure is disclosed in which screen disks and spacer rings are connected together in modular relation. The spacer rings consist of resilient plastic annular rings spaced around the periphery of a shaft and intermediate between screen disks so as to accommodate limited tilting of the disks relative to the axis of the shaft with deflection of the spacer rings. The flexible spacer rings allow foreign objects to work their way out of the disk screens and not become lodged between neighboring screen disks. Metallic surround may be provided to protect the plastic spacer rings from scratching and gouging. |
