ABSTRACT:
In the drive assembly (10) of a reciprocating slat conveyor, three transverse drive beams (28, 30, 32) extend over and across three piston rods (22, 24, 26). The drive beams (28, 30, 32) have side flanges (74, 76) in which three pairs of downwardly opening recesses (78, 84, 80, 86, 82, 88) are formed. One pair of recesses (80, 86) receive upper portions of a first piston rod (22). The other two pairs of recesses (78, 84, 82, 88) receive plastic bearings (90) through which the other two piston rods (24, 26) extend. Each drive beam flange (74, 76) is provided with a cap member (142). Each cap member (142) includes an upwardly directed recess for each downwardly directed recess in its drive beam flange (74, 76). Bolts (144) extend through openings in the cap members (142) and thread into internally threaded openings in the drive beam flanges (74, 76). Each piston rod (22, 24, 26) is provided with a member (70) which provides radially upwardly projecting pairs of flanges (100, 102) between which the drive beam flanges (74, 76) are situated. This provides an interlock structure that connects the piston rods (22, 24, 26) to the drive beams (28, 30, 32) so that piston rod motion is transmitted to the drive beams (28, 30, 32). As each drive beam (28, 30, 32) moves front to rear along with its piston rod (22, 24, 26), it slides relatively along the other two piston rods that are situated in bearings (90) that are carried by the moving drive beam. The engagement of the drive beams (28, 30, 32) with the piston rods (22, 24, 26) via the bearings (90) results in each drive beam (28, 30, 32) being braced from the other two piston rods against yaw, pitch and roll movement.
