ABSTRACT:
An improved construction for a crowned and lagged pulley for a belt conveyor includes a roller tube having a central portion and two outer end portions. A pair of circumferentially extending grooves are formed in the outer surface of the roller tube between the central portion and respective end portions. An elastomeric member is disposed around the central portion of the roller tube and includes first and second end received in respective grooves such that the ends of the elastomeric member lie flush with the outer end portions of the roller tube. The thickness of the elastomeric member, when added to the outside diameter of the roller tube, produces a crown. Also, the elastomeric member serves as lagging for the pulley.
