Abstract: In accordance with one aspect of the present disclosure, a wear ring assembly is provided for a railway roller bearing. The wear ring assembly includes a wear ring having a central opening for receiving a journal of a railway wheel assembly and an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal. The spacers are spaced apart from each other about the wear ring. The insert may include one or more flanges that separate the wear ring from a bearing cone.

Abstract: The disclosure relates to a generator system for rail vehicles, for example, a system including a generator with a rotor and a stator, and a journal box unit. The journal box unit may include a bearing for mounting an axle, and a bearing housing. An end cap is arranged on the front face of the axle. The end cap is connected to the axle for co-joint rotation therewith, and the stator is connected to the bearing housing. A friction wheel is arranged on the outer circumferential surface of the end cap, the friction wheel being designed as the rotor of the generator.

Abstract: A railway vehicle and an axle box structure thereof are provided. The axle box structure includes an axle box body and a positioning node mounting seat. The axle box body includes an upper box body and a lower box body. The upper box body and the lower box body enclose a bearing mounting chamber together. A lower end surface of the upper box body has a convex portion, and an upper end surface of the lower box body has a concave portion. A first semi-circular hole and a second semi-circular hole are respectively provided at the middle of the upper box body and the lower box body. If the convex portion and the concave portion are assembled in a sealed coupling manner, the bearing mounting chamber is formed by the first semi-circular hole and the second semi-circular hole.

Abstract: A railroad car bearing adapter assembly configured to be employed in combination with a high warp restraint truck (with or without an auxiliary or original warp restraint system), and including a low profile thickness and relatively longitudinally narrow roller bearing adapter, a low profile adapter shear pad with a shear stiffness in a range of 85,000 lbs/in to 125,000 lbs/inch, and side wear pad that in combination total clearance in a range of 0.09 inches to 0.36 inches between the side frame thrust lugs and the adapter with the side wear pads. This overall combination reduces wheel wear and damage, reduces fuel consumption, reduces the need for railroad track repair, improves high speed stability and curving performance for both empty cars and loaded cars, provides more truck stability under a loaded car in shallow curves and while encountering certain perturbations, and provides optimum curving performance that enables the axles to better align with curves of relatively high degrees.

Abstract: An axle bearing device includes an inner ring fixed to an axle of a railway vehicle, an outer ring fixed to a journal box of the railway vehicle, and double row tapered rollers arranged between raceway surfaces of the inner ring and raceway surfaces of the outer ring. An opening portion between the inner ring and the outer ring is sealed by a labyrinth seal including at least one axial labyrinth extending in an axial direction and at least one radial labyrinth extending in a radial direction. At least one of the at least one axial labyrinth and the at least one radial labyrinth which form the labyrinth seal is formed between an outer-ring-side sealing member mounted to the outer ring and the inner ring or between the outer-ring-side sealing member mounted to the outer ring and an inner-ring-side sealing member mounted to the inner ring.

Abstract: The invention relates to a railway car truck incorporating a novel interconnection between the side frame and bearing adapter characterized by a low lateral spring constant relative to the longitudinal spring constant. The interconnection provides a proportional restoring force with minimal internal friction and hysteresis. In embodiments, the interconnection comprises compressed elastomeric members positioned between the thrust lug of the side frame and the bearing adapter in the longitudinal direction and a low friction interface between the roof of the pedestal jaw and the top of the bearing adapter.
