DRIVE SPROCKET FOR MONORAIL SUSPENDED CONVEYOR

摘要

A monorail suspended conveyor system for conveying materials along a curvilinear path has a plurality of tandemly disposed belt supporting carriages. Adjacent carriages are connected by an articulated joint suspended from the overhead rail which provides for universal movement of one carriage relative to another. The orbital conveying belt which includes a flexible chain attached to and extending longitudinally along the centerline of the belt is driven by a twin sprocket having alternating pitch teeth which driveably cooperates with the links of the chain so as to decrease the increase of tension in the belt as the same travels around the sprocket.
