A profiled rolling apparatus for lowering rolling resistance in track-guided, load-bearing movement applications. The rolling body, as part of a track roller, cam follower, caster wheel, or the like, has a radial groove (e.g. a V-shape with some internal angle) on which a non-linear profile is implemented. Profiles for various embodiments may be, but are not limited to, circular arcs, polynomials or other mathematical functions, or made up of multiple shorter linear and/or arc segments, creating a convex or concave contour on either side of the groove. Such crowning profiles may additionally or alternatively be implemented on the guiding track.

Rolling apparatus with profiled V-guide

A directional discharge wing pulley having a plurality of wings that discharge material in a single direction while properly tracking the conveyor belt. The directional discharge wing pulley may include a plurality of directional discharge wings, which are generally angled in a single or primarily in single direction across the entire face of the pulley. When pulley is operated a reverse rotation direction, the conveyor belt continues to properly track and the material is discharged in the opposite direction. The wings may have bends to create flat sections, or formed in a multiple arc pattern to create smoother changes in geometry or increased wing angle near the ends of the pulley, while generally maintaining a single direction wing through the entire pulley. Strengthening rib bends may be added near the end of a straight wing to add rigidity reducing the likelihood of wing fold over. The wings may include secondary wings, for example, in a Herringbone pattern. In some applications, the wings may include longitudinal or circumferential wing tips. In other applications, the wings may include a multi-start spiral.

Directional discharge wing pulley

A formed wing pulley for use in belt conveyor applications. The pulley consists of a plurality of formed wings with or without clean-out ports, mated to a positive placement polygon shaped core. The polygon core may be mated to hubs and/or end disks with centered hubs, which can be locked onto to a fixed or rotating shaft. Each formed wing of the pulley may be mated to the positive placement polygon core at the bottom side of the wing profile, and can have round, half round, hex, or flat wing tips that serve as the contact surface or the tops of wings may serve directly as the contact surface for the belt at the top side of the wing profile. When in assembled form, the formed wing pulley provides a set of radial wings that rotate about a central axis to support conveyor belt operation.
