ABSTRACT:
A wheel mounting assembly for a rail-supported storage/retrieval machine. The drive and idler wheels are each mounted on a removable module which includes a fixed plate having a concave spherical surface formed in it and movable plate to which the wheel is mounted having a convex spherical surface interfitting with the concave surface on the fixed plate to define a spherical joint. The plates are interconnected by bolts fitting loosely in oversize holes formed in the fixed plate and threaded into the movable plate to provide limited relative movement of the plates about a plurality of axes. Four jackscrews arranged in pairs on opposite sides of the movable plate are threaded through a frame holding the first plate and bear against the sides of the second plate. Simultaneous tightening and loosening among combinations of the four jackscrews provides horizontal and vertical alignment of the wheel relative to the rail on which the machine is supported. After proper alignment is achieved the bolts are tightened to provide a clamping force between the spherical surfaces.
