    FIELD OF THE INVENTION
    [01] This invention relates to roller bearings and, more particularly, to tapered roller bearings installed on railway freight car axles. BACKGROUND OF THE INVENTION
    [02] Tapered roller bearings on railway wagon axles support an operational load capable of producing deflections by flexing on the shaft and, in particular, on the shaft end part comprising the trunnion to which the tapered roller bearing is fixed. The stresses imposed by the operational load are particularly high in or near the reinforcement ring of the shaft in the reinforcement ring.
    [03] As a result of deflections of the shaft, the reinforcement ring and the sleeve may experience frictional wear as the reinforcement ring moves in relation to the sleeve. Frictional wear can be sufficient to loosen the reinforcement ring, increasing the axial play of the bearing in the journal. The loose reinforcement ring accelerates wear on the bearing and journal assembly, potentially leading to shaft or bearing failure.
    [04] The design of the reinforcement ring is a single piece component with an angled section that fits the dust cover of the shaft. SUMMARY OF THE INVENTION
    [05] To reduce the potential for friction wear in the trunnions and reinforcement rings, a set having greater stability to reduce friction wear is presented. The set consists of two components: (1) a reinforcement ring installed in the trunnion and (2) a locking ring to connect to the reinforcement ring and additionally fix it to the trunnion. The locking ring has an outer side end that fits the reinforcement ring and an inner side end adjacent to the outer diameter of the dust part of the shaft. The locking ring reduces axial movement in the reinforcement ring resulting from deflection of the shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
    [07] With reference to figure 1, a first embodiment of the reinforcement ring assembly of the present invention is shown. In this embodiment, the bearing assembly 10 is a tapered roller bearing of the type commonly used in railway applications to support a rail wagon wheel on an axis.
    [08] Typically, the bearing assembly 10 is pre-assembled before being mounted on the rail car axle 14. At each free end of the axle 14, a trunnion 12 ends in a slightly tapered tapered section 15 to facilitate installation of the rail assembly. bearing 10 on the trunnion. The bearing assembly 10 is pressed onto the trunnion 12 of the shaft 14 to establish an interference fit.
    [09] A dust guard 18 having a larger diameter than trunnion 12 is located axially into trunnion 12. Axially into dust guard 18, shaft 14 extends to its largest diameter. The weight of the railway wagon is transferred through the bearing assembly 10 to the axle and additionally transferred to the rails through the wheels of the railway wagon (not shown) installed inside the dust cover on the axle.
    [10] Some bearing assemblies 10 have wear rings 22, 24 installed on trunnion 12 and which touch each end of the bearing assembly 10. Typically, wear rings 22, 24 have an internal diameter dimension to provide a fit interference in trunnion 12 over at least part of its length. Wear rings 22, 24 rotate with the shaft as it rotates.
    [11] Although the bearing assembly 10 is pressed on the sleeve 12, in general, additional restriction in relation to axial loads is required. To provide this axial constraint, the bearing assembly 10 is captured between a reinforcement ring assembly 60 on the inner side and a bearing retaining cap 20 on the external side of the bearing assembly 10.
    [12] Now, in relation to figure 2, also, on the inner side of trunnion 12 of shaft 14, the bearing assembly 10 is captured by the reinforcement ring 61 through the stop on the wear ring 24. The reinforcement ring 61 has an inner contoured surface 66 that allows a tight surface fit having a complementary surface on the thread 16 at the inner end of the trunnion 12. The thread 16 leads to a shoulder 17, the shoulder extending to form a dust jacket 18 having a surface cylindrical 19. The reinforcement ring 61 has a distal inner edge 63 on the contoured surface 66, generally touching the fillet 16. The reinforcement ring 61 includes a radially outer section 62 and a radially inner section 64 that together form a cutting section 65.
    [13] The locking ring 71 has an inner side end75 adjacent to the cylindrical surface 19 of the dust guard 18. The outer side end of the locking ring 73 fits into the cutting section 65 of the reinforcement ring 61 and restrains the reinforcement ring 61 against deflection and axial displacement. The reinforcement ring 61 and the locking ring 71 together form the reinforcement ring assembly 60. The locking ring 71, the innermost component fixed to the trunnion 12, fixes the bearing assembly 10 in relation to the axially displacement. inside.
    [14] At the outer end of the trunnion, the bearing assembly 10 is captured by the bearing retention cap 20 through the interposed and bordering external wear ring 22. The bearing retention cap 20 is attached to the free end of the trunnion 12 with screws of conical thread or cylindrical thread screws of cap 21 threaded into a plurality of threaded holes. The bearing retaining cover 20 completes the assembly of the bearing assembly 10 on the trunnion 12, providing a clamping force to restrict the bearing assembly from axially outward displacement.
    [15] Bearing assembly 10 is pre-assembled from a number of individual components, including two cylindrical bearing cones 38, 40 and a cylindrical bearing cup 31. The bearing cup 31 has an internal surface having external tracks radially directed to inside 32, 34. Bearing cones 38, 40 have internal tracks directed radially outwards 39, 41. A central spacer 47 is positioned between the cones of bearing 38, 40 to keep the cones in precisely spaced position with respect to each other and allow appropriate lateral clearance of the bearing. The outer tracks 32, 34 in the bearing cup 31 cooperate with the inner tracks 39, 41 in the bearing cones 38, 40 to capture and support two lines of the tapered rollers 42, 44. In some embodiments, cages 46, 48 maintain their positioning circumferential space of rollers 42, 44.
    [16] Bearing seals 50, 52 cover the ends of the bearing assembly 10 to minimize both leakage of bearing lubricant and intrusion of contaminants into the bearing interior. In a first embodiment, the bearing seals 50, 52 are attached to the stationary (i.e., non-rotational) side of the bearing assembly 10 (such as the bearing cup 31) by interference fit or other appropriate method.
    [17] A seal body 56 (typically of an elastomeric construction, generally cylindrical) is part of the bearing seal 50, 52 to form a dynamic seal between stationary and movable components of the bearing assembly. In one embodiment, the sealing body 56 is pushed against the wear ring 22, 24 to seal the bearing assembly 10. A first radial edge 57 of the sealing body 56 is received against an inner radial surface 33 of the bearing cup 31 A second radial edge 59 of the seal body 56 extends radially inward and has a resilient seal 58 attached to it. The resilient seal 58 contacts the outer radial surface 23 of the wear ring 24.
    [18] Cylindrical wear rings 22, 24 protect the trunnion 12 against wear by rubbing the sealing body by providing a wear surface 23.
    [19] With reference to figure 2, the reinforcement ring assembly 60 of figure 1 is illustrated in an enlarged sectional view. Reinforcement ring 61 has an internal contoured surface 66 adjacent to trunnion 12 on the complementary surface of fillet 16.
    [20] A slit or cutting section 65 in the surface directed axially into the reinforcement ring 61 receives the laterally outer end 73 of the locking ring 71.
    [21] A resilient seal ring 79 is present in a notched section 78 of the locking ring 71. The resilient seal ring 79 contacts and forms a seal having the cylindrical surface 19 of the dust cap 18 of the shaft 14. The seal ring resilient 79 can also contact and form a seal having the radially inner section 64 of the reinforcement ring 61. Typically, the resilient seal ring 79 is composed of a polymer, such as polypropylene.
    [22] The locking ring 71, with its connection between the reinforcement ring 61 and the cylindrical surface 19 of the dust guard 18, reinforces and anchors the reinforcement ring 61 against axial displacement and deflection. It is believed that the flexibility of the locking ring 71 allows the reinforcement ring 61 to move more readily with the deflection of the trunnion 12, still allowing the locking ring 71 to restrict the axial displacement of the reinforcement ring 61.
