Abstract: A wheeled support assembly for conveyors includes a wheel assembly having an outer race, an inner race, a plurality of rolling elements positioned therebetween, and a support or bracket. The bracket defines a noncircular aperture in cross section, and the inner race defines a noncircular through bore in cross section. A support shaft having a headed portion extends through the inner race and into the bracket aperture. The support shaft has a noncircular in cross section outer surface which is engaged by the inner race and the bracket aperture to prevent relative rotation. The support shaft defines a threaded bore which receives a threaded fastener extending through the bracket aperture. The support shaft, inner race and bracket are dimensioned so that the shaft normally extends into but not through the bracket aperture, permitting convenient removal of the wheel without disturbing the support or bracket.

Abstract: A trolley or carriage assembly for conveyors, including overhead and in-floor conveyors, in which the inner race of a wheel assembly, a shield or seal for the wheel, and a support for supporting a work piece to be transported by the trolley or carriage assembly are simultaneously locked against rotation with respect to each other and a supporting and retaining shaft by the non-circular outer circumference of the shaft and corresponding non-circular apertures of the inner race, shield or seal and support. Preferably the shaft is a hexagonal, headed bolt or rivet which may include a relubrication passageway for use in closed, sealed wheels. The assembly provides better load distribution, easier assembly in and disassembly from conveyors, and longer, more durable and wear-resistant operation, especially with stamped, sheet metal trolley brackets.
