Sealing arrangement for idler rollers used in weighing roller belts

Abstract

Disclosed in one example is an idler roller for a conveyor belt weighing system, comprising a static shaft, and a load cell fixed to the static shaft and positioned at least partially internal to the static shaft and at an end of the static shaft, the load cell for supporting the idler roller on a frame. A rotating shaft seal is positioned on an exterior surface of the static shaft and internal to the idler roller. A static seal is positioned between the load cell and an interior surface of the static shaft. The static shaft includes a first pocket into which the load cell is inserted and fixed, the static shaft also includes a second pocket into which the load cell is inserted and fixed. The load cell includes one or more strain gauges, and the load cell is rigidly fixed in the end of the static shaft.
