ABSTRACT:
A conveyor construction includes a frame, a drive section stationarily mounted to the frame, and a tensioning section mounted for longitudinal movement relative to the frame. The drive and tensioning sections each include a spindle, and a belt is engaged with the spindles. The frame defines an upper support surface disposed below the upper run of the belt, and mating engagement structure is provided on the belt and the upper support surface for preventing lateral movement of the belt relative to the upper support surface. The drive and tensioning sections include spaced side members, each of which defines an inwardly opening cavity for receiving a bearing assembly for rotatably supporting the spindle. The bearing-receiving cavity faces the spindle, and each side member defines outer wall structure which engages and supports the belt outwardly of the spindle. The belt overlies the outer wall structure of each side member and the adjacent belt-engaging portion of the spindle, so as to seal the inwardly facing opening and prevent ingress of moisture or other contaminants into the bearing-receiving cavity.
