ABSTRACT:
A trim chain take-up sprocket assembly for a mining machine or the like. The sprocket assembly comprises a pair of opposed and axially aligned spindles constituting mirror images of each other, each spindle having a hub rotatively mounted thereon on suitable bearing means. Each hub has at its outboard end a plurality of sprocket teeth and at its inboard end an annular flange. The hub flanges lie in abutting relationship at the longitudinal center of the sprocket assembly and are detachably joined together. Each spindle at its outboard end has a hydraulically actuable piston-cylinder arrangement adapted to engage an abutment surface on the mining machine whereby the entire sprocket assembly may be shifted longitudinally of the mining machine to take up slack or impart slack to the one or more trim chains engaged by the sprocket assembly. Washer-like spacer means are removably affixable to the pistons of the sprocket assembly to retain the assembly in adjusted position. In another embodiment, the hubs themselves are free of sprocket teeth. The hub flanges are detachably joined to an intermediate sprocket wheel bearing sprocket teeth located at the longitudinal center of the sprocket assembly. In all embodiments the sprocket teeth may be eliminated and an annular flange substituted therefor serving as a roller for the chain engaged thereby.
