TROLLEY WHEEL TECHNOLOGY

摘要

The invention provides a trolley wheel assembly (10) for a conveyor system, e.g., an overhead conveyor system. In certain embodiments, the wheel assembly (10) includes at least one wheel face (20) having a contour (optionally a funneling configuration and/or one or more surface features) configured to facilitate flow of a fluid toward an open bearing assembly (14) of the wheel assembly (10). In some embodiments, the wheel assembly (10) includes an inner race (30), outer race (32), and bearings (34) having a particular hardness arrangement, optionally together with a polymer wheel (12) having certain filler features. Methods for cleaning such a trolley wheel assembly are also provided.
