A fillet rolling tool for deep rolling journal fillets (62) is provided. The tool includes a housing assembly (74) having a cavity (75). A backup roller (80) having an annular groove (82) is disposed in the cavity and is rotatabl y supported by the housing assembly. A work roller (88) is received in the annular cavity for deep rolling journal fillets. At least one cage (90), constructed from a polymer material, has an arcuate recess that receives the work roller. The cage includes an outer wall (106) that defines a portion of the arcuate recess (104). Preferably the polymer is a thermal plastic such a s a high density polyethylene. Most preferably, the polymer is an ultra high molecular weight polyethylene. The polymer of the present invention has a ductility, an impact strength, and a wear resistance that is superior to tho se of bronze. Accordingly, the polymer cage of the present invention does not fracture as easily as bronze under the lateral forces of the fillet rolling process. |
