DETAILED DESCRIPTION OF THE INVENTION Some terminology is used in the following description only for convenience, without being limiting. The words "inner", "inward" and "outward", "outward" refer respectively to directions to and away from a designated midline or a geometric center of a element being described, the particular meaning easily appearing from the context of the description. Furthermore, as used herein, the terms "connected" and "coupled" are both intended to include direct links between two elements, with no other element interposed between them, and indirect links between elements. , in which one or more other elements are interposed between the first two. The terminology includes the words specifically mentioned above, their derivatives and words of similar meaning.
    Referring now in detail to the drawings, throughout which like numbers are used to designate similar elements, Figures 1 to 22 show a bearing ring assembly 10 for a railway vehicle axle assembly 1, the axle assembly 1 comprising a shaft 2 with a central axis As and a bearing 3 mounted on the shaft 2. The axle shaft 2 has an enlarged section 4 having an outer circumferential surface 5 in the cylindrical assembly and a section 6 leave curve connecting the enlarged section 4 with the rest of the shaft 2. The support ring assembly 10 roughly comprises a support ring 12 in the annular assembly, which can be arranged on the shaft 2 between the bearing 3 and the enlarged section 4 of the shaft, and a retaining device 14 in the tubular assembly. The retaining device 14 is configured to engage the enlarged section 4 of the shaft and to retain the bearing ring 12 in a fixed axial position on the shaft 2.
    More specifically, the support ring 12 comprises a body 16 in the cylindrical assembly having a central axis Ar and first and second axial ends 16a, 16b spaced along the axis Ar. The body 16 of the ring support has an inner circumferential surface 15, delimiting a central bore 18 to receive a portion of the shaft 2, and an outer circumferential surface 17, the inner and outer surfaces 15, 17 extending axially between the respective ends 16a, 16b and circumferentially around the axis Ar. Preferably, the inner surface 15 of the bearing ring comprises a section 15a of curved surface (most preferably the entire surface 15) juxtaposed against the fillet section 6 of the when the support ring 12 is disposed on the shaft 2, thereby allowing the support ring 12 to fit tightly adjacent to the enlarged section 4 of the shaft 2. Also, the body 16 of the bearing ring is preferably shaped so that the first axial end 16a of the body is generally in or near a radial plane P (dashed lines in FIGS. ) passing through the intersection of the enlarged section 4 of the shaft with the fillet section 6 of the shaft, so that the support ring 12 does not extend over or over the enlarged section 4 of the tree.
    In addition, the support ring 12 comprises a shoulder or retaining surface 20 extending radially in all on the side opposite to the enlarged section 4 of the shaft and thus turned in the assembly. to the bearing 3, when the bearing ring 12 and the bearing 3 are arranged on the shaft 2. The retention surface 20 preferably extends generally radially inwardly from the outer surface 17 of the ring near the second axial end 16b of the body and is most preferably formed on the second end 16b of the body. Also, the shoulder surface 20 is preferably a radial surface in the substantially continuous annular assembly (as shown), but may take the form of one or more surface sections in the arcuate assembly and / or may be extend in part axially relative to the axis Ar. Preferably, the body 16 of the bearing ring further comprises a shoulder 19 in the annular assembly extending axially from the second end 16b of the body and delimiting around the shaft a pocket 19a in the annular assembly for receiving an axial end 7a of a sealing collar or wear sleeve 7 annular of the bearing assembly 3, as shown in Figures 1 and 2.
    In addition, the retaining device 14 preferably comprises a body 22 in the annular assembly, which can be arranged around the enlarged section 4 of the shaft, and at least one coupler 24, connected to the annular body 22 and configured to engaging the bearing ring 12. The annular body 22 of the retainer has opposite axial ends 22a, 22b, respectively outer and inner, an inner circumferential surface 23A, sized to frictionally engage the cylindrical surface 5 of the enlarged section of the shaft, and opposite an outer circumferential surface 23B. Said coupler 24 of the retainer is connected to the inner end 22a of the annular body and is preferably configured to engage the radial retention surface 20 of the backup ring to removably connect the annular body 22. of the retaining device with the support ring 12, so as to thereby retain the ring 12 at a substantially fixed axial position on the shaft 2. In other words, the frictional engagement of the armature body 22 of the retaining device with the enlarged section 4 of the shaft removably attaching the retaining device 14 to the shaft 2 so that the engagement of the coupler 24 of the retaining device with the support ring 12 acts to this fact to fix / retain axially the support ring 12 on the shaft 2.
    Referring in particular to Figures 1 and 2, at least the annular body 22 of the retainer 14, and most preferably the entire retainer 14 as discussed below, consists of a substantially expandable material, such as for example a polymer, a metallic material, etc. As such, the central bore 18 of the retainer 14 is adapted to separately receive one or the other of a plurality of shafts 2 of different sizes or dimensions. Specifically, each shaft 2 comprises an enlarged section 4 having an outer diameter ODs (FIG. 2), which may have a value different from the value of the OD of enlarged section of each of the other shafts 2 of said plurality. Thus, the retainer 14 is capable of receiving or engaging a number of different shafts each formed with an enlarged section 4 having an OD OD in a range of values. As such, the bearing ring assembly 10 can be adapted for use with a variety of shafts 2. Also, thanks, at least in part, to the expandability of the annular body 22 of the retainer, the inner surface 23 of the annular body is configured to be in sealing contact with the outer surface 5 of the enlarged shaft section. Preferably, the sealing contact is improved by forming at least the annular body 22 from a polymeric material, by doubling the inside of a metal annular body 22 with a polymer or by any other suitable means. to increase the seal between the annular body 22 and the enlarged section 4 of the shaft. In any case, the sealing contact between the retainer 14 and the shaft 2 functions to prevent the entry of water or other liquids into the portion of the shaft 2 surrounded by the bearing ring assembly 10, which otherwise could result in the oxidation of the metal support ring 12.
    Referring now to Figures 2, 6 to 8, 16 and 18 to 22, the retainer coupler 24 preferably comprises a body 25 in the tubular assembly connected to the annular body 22 of the retainer and which can be arranged around the cylindrical body 16 of the support ring. Alternatively, the coupler 24 of the retainer may consist of a plurality of elongate tabs (not shown), each having a first end integral with the body 22 of the retainer and opposite a second free end which engage the retention surface 20 of the backing ring. With the preferred structure, the tubular body 25 has a first end 25a race at the second end 22b of the annular body of the retainer, a second end 25b engageable with the shoulder surface 20 of the support ring. , an inner circumferential surface 26 which may be disposed around the outer circumferential surface 17 of the bearing ring and defines a central bore 29 open and an outer circumferential surface opposite 27. When the preferred retainer 14 is installed on the support ring 12, the second end 25b of the tubular body of the coupler is located at least in the assembly near the second axial end 16b of the support ring and is configured to engage the surface of the Retention shoulder 20, as described in detail below. Preferably, the tubular body 25 of the retainer coupler is integrally formed with the annular body 22 of the retainer, so that the annular body 22 and the coupler 24 are integral parts. a retaining device 14 of monobloc structure. Alternatively, the tubular body 25 of the coupler may be attached to an annular body 22 separated by any suitable means (e.g., fasteners, adhesives, plastic welding, etc.).
    In any case, at least a portion of the preferred tubular body of the retainer coupler is configured to flex radially overall when the retainer 14 is installed on the support ring 12 and otherwise when the device is removed. retainer 14 of the bearing ring 12, so that the tubular body 25 of the retainer coupler is configured to fit tightly around the cylindrical body 16 of the bearing ring. Most preferably, the cylindrical body 16 of the bearing ring is formed with a decreasing section axially so that the outer circumferential surface 17 is generally frusto-conical. Specifically, the outer surface 17 of the body preferably extends axially axially between a first smaller diameter axial edge 17a near the first axial end 16a of the bearing ring and a second axial edge 17b further large diameter near the second axial end 16b of the bearing ring, the retaining shoulder surface extending radially inwardly from the second axial edge 17b, as shown in Figures 13 and 14.
    With such a bearing ring structure, at least the inner surface 26 and, most preferably, the entire tubular body 25 of the coupler 24 of the preferred retainer is generally frustoconical and dimensioned to be disposed or juxtaposed closely around the outer surface 17 of the support ring. More particularly, the inner circumferential surface 26 of the tubular body 25 of the retainer coupler has a smaller diameter first axial edge 26a near the annular body 22 of the retainer and opposite the second axial edge 26b further large diameter, as shown in Figure 19. The smaller edge 26a of the inner surface 26 of the tubular body has a dimension slightly greater than the smallest edge 17a of the outer surface 17 of the support ring and the largest edge 26b of the inner surface 26 of the tubular body is slightly larger than the second edge 17b of the outer surface 27 of the support ring.
    As such, the backing ring 12 and the retainer 14 are shaped so that the coupler 24 of the retainer encapsulates the backing ring 12 to prevent fluid entry between the ring 12 and the coupler 24. In addition, the complementary frustoconical structures of the support ring 12 and the coupler 24 of the retainer facilitate the installation of the retaining device 14 on the support ring 12, as discussed in detail below. Preferably, the retainer 14 further comprises a plurality of anti-rotation ribs 40 spaced along its circumference, each extending between the inner surface 27 of the coupler body and the inner end 22b of the coupler body 22. . Each rib 40 may be disposed in a separate pocket among a plurality of locating pockets 42 formed on the first axial end 16a of the bearing ring body 16 to prevent relative angular displacement between the retainer 14 and the support ring 12.
    As best shown in Figures 16 and 18 to 23, the coupler 24 of the retainer preferably comprises at least one engagement lip 30 extending radially inwardly from the second end 25b of the tubular body and can be arranged against the retention surface 20 of the support ring. Preferably, the coupler 24 of the retainer comprises a plurality of lips 30 in the arc-shaped assembly having opposite circumferential ends 30a, 30b, the lips 30 being spaced along the circumference about the central axis Ar of the ring. Alternatively, the body of the coupler of the retainer may comprise only one continuous annular lip (not shown). Preferably, the tubular body 25 has a plurality of pairs of parallel notched openings 32 extending axially inwardly from the second end 25b of the body at a circumferential end 30a, 30b separated from each lip 30. Each pair of apertures 32 defines one of the plurality of mounting tabs 34 in the generally arcuate and rectangular assembly. Each mounting tab 34 carries a separate lip among the shaped lips (Tare of the retainer and may in the aggregate be flexed relative to the remainder of the body 25 in generally radial directions to move the connected lip 30 in engagement with the retaining surface 20 of the support ring and, if not to separate it from each other, each tongue 34 has an inner end 34a forming an integral part of the rest of the body 25 and can be flexed around said end at the way of a cantilever beam for radially moving the second opposite outer end 34b and thereby also the connected engagement lip 30, as shown in FIG. 23.
    In addition, the tubular body 25 preferably also has a plurality of arcuate pockets 36 extending axially inwardly from the second end of the body and radially outwardly from each mounting tongue 34, each pair of notched openings 32 radially penetrating into an adjacent pocket among the pockets 36. The pockets 36 substantially reduce the radial thickness of each mounting tongue 34, thereby facilitating bending radial of each tab 34 and provides a closed space for such movement of the tab 34 adjacent to prevent it from being damaged. However, the tubular body 25 may alternatively be formed with a substantially smaller radial thickness than that generally shown in FIGS. 16 to 21 and with the notched openings 32 passing through the entire body thickness, so that the tabs mounting 34 are not surrounded by any pocket, as shown in Figure 22.
    Referring now to FIGS. 1 to 3, 5, 7, 8 and 15 to 20, the annular body 22 of the retainer preferably has a disassembly surface 38 extending substantially radially on the outer axial end 22a. . The disassembly surface 38 preferably extends in the circumferential and radial directions along the entire outer end 22a of the body but may be formed only on a radial section of the outer end 22a, or even on discrete parts arcuate surface (not shown either). In addition, the disassembly surface 38 is intended to cooperate with a disassembly tool (not shown) to axially move the body 22 of the retaining device out of the enlarged section 4 of the shaft and, therefore, the disassembly ring. support 12 along the shaft 2 to remove it. Preferably, as shown in FIG. 17, the disassembly surface 38 has an inner edge 38a with a first radius R 1 and an outer edge 38 b with a second radius R 2, the difference between the value of the second radius R 2 and the value of the first radius Ri being at least seven hundred and fifty thousandths of an inch (0.750 "). As such, the bearing ring assembly 10 is capable of meeting the requirements of the railway vehicle industry for disassembly by the 'user.
    As shown in FIGS. 3, 5, 15 and 17, the annular body 22 of the retainer preferably further comprises at least one and most preferably a plurality of lightening recesses 44 extending into the housing. together axially inwardly from one of the two axial ends 22a or 22b. These cavities 44 are used to reduce the amount of material required to form the magnet body 22, which is advantageous for certain manufacturing techniques, such as injection molding, and reduces the material costs and the weight of the product. When the cavities 44 are formed extending inwardly from the outer end 22a, as shown in Figures 3, 5, 15 and 17, the disassembly surface 38 is collectively formed of lower and upper circumferential sections 39A, 39B and a plurality of radial sections 39C extending between the circumferential sections 39A, 39B.
    Referring to Figures 1, 2 and 23, the backing ring assembly 10 is preferably assembled in the assembly as follows. First, introducing the first axial end 16a of smaller diameter of the body 16 of the bearing ring into the central bore 29 of the tubular body 25 of the preferred retainer and then axially moving the body 16 of the ring by the bore 29 of the retainer until substantially all of the body 16 is disposed within the bore 29. At this point, said preferred engagement lips 30 of the coupler 24 of the retainer flex radially outwardly and inwardly to engage the retention surface 20 of the backing ring. Due to the complementary conicities of the outer surface 17 of the bearing ring and the inner surface 26 of the tubular body of the retaining device, the introduction of the bearing ring 12 into the retaining device 14 is greatly facilitated by a game that remains until the surfaces 17, 28 become substantially juxtaposed.
    In any case, when the retaining device 14 is installed on the bearing ring 12, the bearing ring assembly 10 is then mounted on the rail vehicle axle shaft 2 by introducing an end 2a ( 1) of the shaft 2 by the bore 18 of the bearing ring, then moving axially all of the assembly 10 to the enlarged section 4 of the shaft until the annular body 22 of the retainer engages circumferentially around the enlarged section 4 of the shaft and that the support ring 12 is disposed against the fillet section 6 of the shaft. At this point, the entire bearing ring assembly 10 is retained on the shaft 2 by the frictional engagement of the inner surface 23A of the retainer and the outer surface 5 of the shaft .
    Alternatively, although this is not the preferred method, the backup ring assembly 10 could be mounted by first installing the retainer 14 on the shaft 2 (i.e. engaging the annular body 22 on the enlarged section 4 of the shaft). Then, the support ring 12 is installed on the shaft 2 and is moved axially towards the enlarged section 4 of the shaft until the ring 12 is disposed inside the bore 29 of the coupler 24 of the retainer.
    When it is desired to disassemble the bearing ring assembly 10, a disassembly tool (not shown) is engaged with the disassembly surface 38 of the retaining device and a pulling force is applied to axially displace the entire assembly. support ring assembly 10 until the inner surface 23A of the retainer disengages from the outer surface 5 of the enlarged section 4 of the shaft. At this point, the whole bearing ring assembly 10 can be moved axially or slidably along axis A-A of the shaft until bearing ring 12 separates from shaft 2. The retainer 24, which is preferably made of a relatively inexpensive material (eg, nylon, polyethylene terephthalate, etc.) can if desired be scrapped and replaced with a retaining device 14 new, while reusing the support ring 12, which may be made of a relatively more expensive material, such as a metallic material (eg, low carbon steel). Those skilled in the art will appreciate that modifications could be made to the embodiments described above without departing from their broad inventive concept. It is therefore understood that this invention is not limited to the particular embodiments presented, but is intended to cover modifications within the spirit and scope of the present invention as generally defined in the present invention. claims in annex.
