Abstract: An axle (A) has a journal (2) to which an antifriction bearing (B) is fitted on an enlarged or dust guard section (4) located beyond the journal, with a fillet (6) leading from the journal up to the enlarged section. A backing ring (R) fits over and against the fillet of the journal and has a counterbore (48) that receives the adjacent end of the enlarged section. A stabilizing ring (S) fits into the counterbore of the backing ring and around the enlarged section of the journal to stabilize the backing ring and thereby reduce radial and circumferential movement between it and the fillet of the journal. The stabilizing ring includes a rigidifying element (54) that fits over the enlarged section of the axle with an interference fit and a more flexible compression member (56) that lies within the counterbore where it exists in a state of compression between the counterbore and the rigidifying element. The stabilizing ring allows some microaxial movement of the backing ring.

Abstract: A backing ring (R) that serves to back an antifriction bearing (B) on the journal (2) of a rail car axle (A) includes an annular body (36, 52, 66, 88, 98, 118, 136, 160, 170, 188, 214, 234, 254) that seats against a fillet (6) that is located at the end of the journal and also a lip (46, 56, 70, 90, 100, 120, 138, 162, 172, 190, 216, 236, 268) that projects over a larger dust guard diameter (4) that is located on the axle immediately beyond the fillet. In addition, the backing ring includes a stabilizing element (38, 54, 68, 96, 102, 122, 142, 166, 178, 194, 224, 242, 256) 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.
