Roller wheel with friction relief

摘要

A flow shelf roller having an outer circumference, a radially central hub, and an axially central bore forming an inner circumference through the central hub. The inner circumference of each roller has at least one axial relief channel formed therein along the length of the axial bore. In a more particular embodiment, the axial relief channel is formed including a non-perpendicular angle with respect to the inner circumference of the roller. In a more particular embodiment, the axial relief channel includes at least one of an angled chamfer and a radiused corner, adjacent to the inner circumference of the first roller. The disclosure also includes a roller flow shelf including a flow bed roller having any or all of the aforementioned characteristics.

主权项

1. A roller flow shelf comprising:
first and second support rails which together define a travel path of the flow shelf; a plurality of axles each having a first outer diameter, each axle connecting the first rail to the second rail, and each axle being generally perpendicular to the travel path of the flow shelf; and a plurality of rollers mounted for rotation on at least one of the plurality of axles, a first roller of the plurality roller of the plurality having:
an outer circumference;a radially central hub connected to said outer circumference by a web or one or more spokes; andan axially central bore forming an inner circumference through the central hub, the central bore having a second inner diameter equal to or greater than the first outer diameter of a corresponding axle on which it is mounted for rotation, whereinthe inner circumference of each roller having at least one axial relief channel formed therein along the length of the axial bore.
