Idler roller conversion system with impact shell

摘要

A roller arrangement for use in a conveyance system includes a generally cylindrical roller body which has a pre-determined diameter, an outer surface, and a central passage. A shaft extends through the central passage, the roller body is rotatable about the shaft. An expander circumscribes the roller body. An impact shell is connected outwardly to the expander. The impact shell includes a cover made of low modulus elastomeric material and a backing layer made of high modulus elastomeric material. A first compression plate, a second compression plate, and a compression ring are mounted to the roller so that the compression ring is mounted between the first plate and the second plate.
