ABSTRACT:
A skirt seal impact bracket for supporting a conveyor belt idler which improves the impact characteristics of a suspension type idler by enabling the idlers to yield under the force of material being loaded thereonto and thereby protects the idler from undue stress and extends the life of the same. The skirt seal bracket includes a mounting assembly for the bearings of the first and second ends of a belt conveyor idler so as to allow arced pivoting of each bearing of the idler about a point substantially corresponding to a contact point of a trough skirt seal and a belt conveyed by the idler. In this manner, downward movement of a central portion of the idler in response to a load impinging thereon causes the pivoting of each of the bearings about the point of contact of the trough skirt seal and the belt. Further, a structure for limiting such pivoting and downward movement is provided. Finally, a configuration for urging the idler to return toward a pre-loaded position is provided for returning the idler following such impact.
