US 2009/0260957 A1 · Low friction roller belt

Abstract

A modular conveyor belt having longitudinal grooves on the top and bottom of the belt. Pairs of rollers are installed between the links within these grooves such that the rollers do not project over the surface of the belt but are completely integrated into the body. The rollers may be installed directly onto the pivot rods. The belts are supported by rails that enter into the longitudinal grooves to engage with the rollers to carry the belt as it moves. The grooves on the bottom side of the single modules are curved in such a way that the slots form a circle when the belt moves around a sprocket. This configuration allows for steel disks to be installed between the sprockets on the driving and idling shaft. The disks help to support the belt and to improve smooth running of the belts around the sprocket under a high load by taking the radial forces acting when the belt is under high tension.
