Abstract
A drop center rim (11) of a fabricated heavy-duty industrial wheel (10) is fabricated from several pieces welded together and includes a backup ring (19) positioned within and welded to the inner periphery of a rim well (13). In some embodiments, each of a pair of reinforcing rings (34,36) has an L-shaped cross sectional configuration with an axially extending portion (37) extending into and welded to the inner periphery of the rim well and a radially extending portion (38) having its outer edge welded to the respective bead seat (14,16) of the rim (11). An annular mounting flange (12) is connected to one of the reinforcing or backup rings and extends radially inwardly therefrom.

In a fabricated heavy-duty industrial wheel (10) of the type having a drop center rim (11), said rim (11) having a rim well (13) and a pair of bead seats (14,16) positioned on opposite sides of the rim well, the improvement comprising:
- a pair of reinforcing rings (34,36) each having an L-shaped cross sectional configuration with an axially extending portion (37) extending into the inner periphery of the rim well (13) and welded thereto and a radially extending portion (38) having its outer edge (39) welded to the respective bead seat;
- an annular mounting flange (12) connected to one of the reinforcing rings (34,36) and extending radially inwardly therefrom;
- and
- wherein said rim (11) is constructed from a backup ring (19) and a pair of identical halves (24,26) seated on said backup ring (19), the halves having inner ends (27) welded to each other and to the backup ring (19), said backup ring (19) having its outer ends (21,22) welded to the rim well (13) of the rim (11).
A fabricated heavy-duty industrial wheel (10) comprising:
- an annular ring (19) having outer ends (21,22);
- a drop center rim (11) having a rim well (13) and a pair of bead seats (14,16) positioned at opposite sides of the rim well, said rim (11) being constructed from a pair of identical rim halves (24,26) seated on said annular ring (19), the halves having inner ends (27) welded to each other and to the annular ring (19), each of said outer (21,22) ends of said ring being welded to the respective rim half by a continuous weld (28);
- a pair of reinforcing rings (34,36) each having an L-shaped cross sectional configuration with an axially extending portion (37) extending into the inner periphery of the rim well (13) and welded thereto and a radially extending portion (38) having its outer edge welded (39) to the respective bead seat and a mounting flange (12) connected to said wheel and extending radially inwardly therefrom.
