Normally, a bearing adaptor is provided over the axle bearing, said adaptor having a slightly arcuate top surface which bears directly against a corresponding downwardly facing surface in the pedestal opening of the side frame.
In service, limited movement or frictional sliding occurs between the bearing adaptor and the pedestal surface, which may cause worn spots on the frame, resulting in sloppiness and a weakening of the frame at a load bearing location. Repair of the frame surface is both expensive and time consuming, since the worn surface must be ground down and renewed by welding a plate in the opening.
SUMMARY OF THE INVENTION The present invention provides a renewable wear plate which is removably attached to the side frame in the pedestal opening and constitutes a wear surface against the bearing adaptor. The plate has resilient side lips which resiliently clamp against the sides of the frame and tend to hold the plate in position during installation and service. Means are provided between the frame and the plate to limit longitudinal movement of the plate relative to the frame, in order to minimize wear on the frame.
THE DRAWING FIG. 1 is a fragmentary elevational view of one end of a railway truck side frame and axle, including the wear plate of the present invention;
FIG. 2 is an expanded perspective view, with portions cut away, of the side frame and axle assembly of FIG. 1, further illustrating the component parts thereof in disassembly;
FIG. 3 is a perspective view of the wear plate shown in FIGS. 1 and 2;
FIG. 4 is a transverse sectional view taken along section line 44 of FIG. 1;
FIG. 5 is a plan view of another embodiment of the wear plate of the present invention; and
FIG. 6 is a view similar to FIG. 1 but further illustrating stops on the frame in engagement with the ends of the wear plate.
DESCRIPTION OF THE PREFERRED EMBODIMENT It will be understood to those skilled in the art that the drawings show only a fragmentary portion of a railway truck, which includes a pair of spaced side frames supported on wheel and axle assemblies, and a bolster connected between the side frames for supporting the car body. FIG. 1 illustrates one end of a side frame 10 terminating in the pedestal 12 in the form of a downwardly open pedestal jaw engaged over the axle I4 on which the car wheels are mounted.
As shown in FIGS. 2 and 4, a roller bearing 16 is carried on the axle 14 near the end thereof, and a bearing adaptor 18 is provided between the top portion of the bearing and the internal surfaces of the pedestal 12. The downwardly facing surface of the adaptor 18 is curved at 20 to correspond to the cylindrical outer race of the bearing 16, and the upper portion of the adaptor comprises a top slightly convex surface 22 which normally bears against a downwardly facing flat surface 24 in the pedestal opening. In addition, side surfaces 26 are provided on the adaptor 18 in engagement with corresponding surfaces 28 in the pedestal opening. Thus the upper portion of the adaptor is generally rectangular so as to be received in the rectangular pedestal opening, although the adaptor corners are omitted or cut away to prevent galling of the comers in the pedestal opening.
The foregoing parts are conventional and details thereof are readily available to the public. It will also be understood that the pedestal at the other end of the side frame is identical to the one described above.
As shown in FIGS. 1-4, the wear plate 30 of the present invention is in the form of a rectangular base plate 32, said plate having a pair of integrally formed lips 34 extending upwardly from opposite sides thereof, said lips being adapted to resiliently clamp inward toward one another against the opposite side surfaces of the pedestal 12 adjoining the central portion of the downwardly facing surface 24. As shown, the lips 34 are coextensive with the length of the base plate 32, which fa cilitates fabrication of the wear plate from a single rectangular metal or steel sheet, although any suitable lip configuration may be employed. It will be noted that the base of the lips 34 each bulge outwardly in an arc at 33 beyond the width of the base plate 32, and the upper edges 38 are inwardly spaced from the base of the lips but are also flared out at their ends to facilitate installation.
The minimum dimension between the lips 34 is smaller than the width of the base plate 32 and the transverse thickness of the pedestal, such that the lips resiliently clamp against the sides of the side frame after the wear plate has been installed. The bulges 33 in the lips serve to accommodate corresponding bulges which are normally cast in the side frame, as shown in FIG. 4. The clamping action of the lips 34 against the side frame serve to minimize side-to-sicle movement of the wear plate relative to the frame.
Additional means are provided to minimize movement of the wear plate on the downwardly facing surface 24 of the pedestal opening. The preferred means is shown in FIGS. 1-4 and comprises at least one, and preferably two or more, longitudinally and laterally spaced protrusions or convex bumps 40 in the upper surface of the base plate 32, and corresponding shallow depressions 42 (FIG. 4) in the downwardly facing surface 24 which conformably receive said bumps. Movement of the bumps 40 out of register with the depressions 42 is prevented because of the considerable load on the friction plate. The restraint feature serves primarily to prevent longitudinal movement of the plate into the corner of the pedestal opening, although it may be seen that lateral movement is also minimized thereby.
FIG. 5 illustrates another version of a wear plate 60 having the same lips 62, but having the bumps 64 formed on the lips instead of the base plate. It is understood that corresponding recesses would be provided in the sides of the pedestal to receive the bumps 64.
FIG. 6 illustrates still another means of imposing longitudinal restraint on a wear plate having the usual lips 72 in engagement with the sides of the pedestal. In
this embodiment, the sides of the side frame are provided with pairs of longitudinally spaced stops 74 which engage the opposite end surfaces of the lips and prevent longitudinal movement of the plate.
In summary, the wear plate 30 of the present inven tion is essentially resiliently capped over the surface to be protected on the side frame, which prevents accidental vertical dislodgment of the plate after installation. The plate is centrally mounted against the downwardly facing flat surface 24 of the pedestal opening, and the ends thereof are spaced from the corners of the opening, in order to prevent wear thereof by the plate. Since no welding or bolting of the plate is required, installation and removal of the plate may be effected very easily with simple tools.
In order to install the plate, the side frame I is lifted away from the axle l4, and the shallow recesses 42 are drilled in the downwardly facing surface 24, and the wear plate 30 is pushed onto the side frame, whereupon the truck may be reassembled.
