Appl. No.:

10/871147

Stephen E. Brister - North Canton OH, US

Assignee:

The Timken Company - Canton OH

International Classification:

F16C 19/50

US Classification:

295 42, 384459, 384584

Abstract:

A backing ring that serves to back an antifriction bearing on the journal of a rail car axle includes an annular body that seats against a fillet that is located at the end of the journal and also a lip that projects over a larger dust guard diameter that is located on the axle immediately beyond the fillet. In addition, the backing ring includes a stabilizing element which cooperates with the lip and with the dust guard diameter to lessen the tendency of the annular body to work against the fillet and create a fretting wear when the journal undergoes cyclic flexures. The stabilizing element accommodates dust guard diameters of varying size. The stabilizing element may also establish a seal between the lip and the dust guard diameter.

International Classification:

F16C 3336

US Classification:

384459

Abstract:

A compact antifriction bearing fits around a journal at the end of an axle for a rail car. The journal extends from an intervening section of the axle, and the intervening section in turn projects from a still larger main section, there being fillets where the sections merge. A backing ring fits against the fillet at the end of the journal, while an end cap fits over the opposite end of the journal. The bearing includes two cones which are clamped between the end cap and backing ring, a double cup surrounding the cones, and tapered rollers arranged in two rows between raceways on the cones and on the cup. The ends of the bearing are closed by seals which are fitted to the cup and cone. The thicker intervening section of the axle is extended in comparison to its counterparts on traditional axles, and the backing ring extends axially along the journal generally no further than the location at which the fillet emerges from the main body of the journal. This presents the back face of the inboard cone in a region where the journal is quite stiff, thereby reducing flexing and fretting considerably.

International Classification:

US Classification:

384584

Abstract:

A bearing assembly fits over the journal at the end of a shaft and is clamped between a fillet at one end of the journal and an end cap which extends across the opposite end of the journal. The bearing assembly includes a double row tapered roller bearing having a two indirectly mounted cones, a double cup around the cones, and tapered rollers arranged in two rows between the raceways of the cones and cup. The bearing assembly also includes seal rings located against the cones and seals fitted into the end of the cup and cooperating with the seal rings to establish barriers at the ends of the bearings. The outboard seal ring is clamped between the end cap and the outboard cone, whereas the inboard seal ring is clamped between the inboard cone and the backing ring. A slight clearance exists between the inboard seal ring and the journal to prevent fretting beneath that seal ring due to slight flexures in the journal. The inboard seal ring fits into a bore on the fillet ring so the fillet ring maintains the inboard seal ring centered with respect to the axis of rotation.
