US 2015/0083547 A1 · CONVEYOR ROLLER ARRANGEMENT

Abstract

A conveyor roller has a drum shell and an end lid that has an end lid, an embossed spring band, and a mounting face that is affixed to an axial end of the drum shell. The end lid has a cylindrical geometry that mates with the mounting face, whereby the embossed spring band is compressed by an interference fit between the two mating cylindrical geometries. A polymeric seal is disposed between the inward face of the end lid and the outward face of the drum shell, near the outer circumference of the end lid. Thus, the end lid maintains a spring force against the polymeric seal. The end lid has a ring compression geometry for exerting a compressive force on the polymeric seal as the end lid is retained against the drum shell by the embossed spring band. A cleaning system has a shaft with cleaning conduits, inlet and outlet ports, and an end lid.
