摘要： A railway car truck includes side frames each having a pedestal formed on longitudinally opposite ends thereof. Each pedestal has an upper jaw and a lower jaw surrounding a pedestal opening. The upper jaw has a roof section above the pedestal opening and the lower jaw has an inner wall and an outer wall on opposite sides of the pedestal opening. The inner and outer walls are spaced apart from one another to define a wide pedestal opening. A bearing adapter is received in each pedestal opening. Each bearing adapter includes a concave opening to receive a bearing and a generally rectangular center section having a top surface generally opposite the concave opening. The bearing adapter has steps extending outward from sides thereof that have outer surfaces separated by a distance corresponding to the width of the pedestal opening. The railway car truck also includes an elastomeric adapter pad mounted on top of the bearing adapter that has a generally flat, generally rectangular top section and depending legs that extend along the outer surfaces of the steps. The top section defines a pad for engaging the roof section. The depending legs define pads for engaging the inner and outer walls.

摘要： A novel two-piece backing ring assembly for a railcar axle is presented. The backing ring assembly has an annular body affixed to the fillet of the journal and a locking ring for further affixing the annular body into position on the journal. The locking ring has an inboard end affixed to the dust guard of the shaft and an outboard end for engaging a slot in the annular body. The locking ring assembly may be retrofitted to older generation railcar axles to increase the structural rigidity of the bearing assembly and minimize fretting wear caused by railcar axle deflection.

摘要： A bearing assembly is provided having a roller bearing with an inner race fitted around the journal portion of an axle. An outer raceway combines with the inner raceway to receive roller elements. A backing ring is centered to the shaft fillet. Tapered roller elements are located between and contact the inner and outer raceways. A cage is comprised of an inner ring, and outer ring, and a plurality of pocket bars and support pocket bars extending between the inner and outer rings. The support pocket bars have an overall greater thickness than the pocket bars. The cage is a generally unitary structure comprised of a nylon resin material with a fiber fill.

摘要： A bearing assembly is provided having a roller bearing with an inner case fitted around the journal portion of an axle. An outer raceway combines with the inner raceway to receive roller elements. A backing ring is centered to the shaft fillet. An annular wear ring is positioned between the inner case and the backing ring. An annular sealant bead or a sealant ring form a seal between the shaft shoulder and the backing ring.

摘要： A labyrinth seal includes a seal case with an inner-diameter leg encircling a rotation axis, and an insert fixed in the seal case and encircling the rotation axis. The labyrinth seal also includes a slinger encircling the rotation axis and wrapping around the inner-diameter leg to cooperate with the seal case to form a first part of a labyrinth path. The slinger rotates relative to the seal case. The labyrinth seal also includes a rotor that encircles the rotation axis, cooperates with the insert to form a second part of the labyrinth path, and interlocks with the insert to limit axial movement of the rotor when the rotor rotates relative to the insert. The labyrinth seal may be combined with a bearing cone, a bearing cup, and a plurality of rollers to form a roller bearing assembly.

摘要： A leather flange for a bidirectional seal assembly includes a radial flange leg encircling a rotation axis of the leather flange. The leather flange also includes an oblique flange leg encircling the rotation axis and joined to the radial flange leg. The oblique flange leg extends both radially inward and axially away from the radial flange leg to form an oblique angle with the rotation axis. An end face of the oblique flange leg forms a sinusoidal pattern around a circumference of the leather flange. The end face also meets an air-side surface of the oblique flange leg to form a lip. When the leather flange is installed around a shaft, the lip forms a sinusoidal path around the circumference of the shaft. As the shaft rotates, the sinusoidal path of the lip creates an axial back-and-forth sweeping action.

摘要： A knuckle of a coupler of a rail vehicle includes a leading beam having a pulling face, a lateral offset beam extending from the leading beam, a tail extending from the lateral offset beam, an extension wall extending from the lateral offset beam towards an end of the tail, and a tapered lock engagement wall extending from the extension wall to the end of the tail. The tapered lock engagement wall is angled in relation to the extension wall. The tapered lock engagement wall is configured to engage an interior face of a main body of a lock of the coupler. The interior face defines a knuckle-engaging surface that is configured to bear against the tapered lock engagement wall.
