摘要： A method for re-manufacturing a worn railroad car wheel is described herein. The method includes identifying a candidate wheel or wheel set, preparing the wheel or wheel set to receive new welding, performing a welding operation on the wheel/wheel set, and performing post-welding steps to ensure the re-manufactured wheel meets a defined profile standard. Preparing the wheel may include cleaning, grinding, and pre-heating one or more surfaces of the wheel.

摘要： This invention relates to a safety wheel, for a subway coach bogie, or the like, running on pneumatic tires, adapted to be interposed between a chassis of the bogie and a corresponding tire, said wheel presenting an outer peripheral zone having a braking portion as well as a guiding portion projecting radially outwardly from the braking portion, the hardness of the braking portion being much greater than the hardness of the guiding portion. This may be achieved for example by effecting a selective tempering of the braking portion by peripheral nozzles projecting a cooling liquid. This safety wheel is considerably longer lasting than those of the prior art.

摘要： A railroad wheel formed from at least two metallic alloys. In one embodiment, a railroad wheel has a body formed from a first alloy and a rim formed from a second alloy initially in powder form. In an exemplary embodiment, to form the dual alloy wheel the body of the wheel is cast with a circumferential channel formed therein. The perimeter of the body is enveloped with a material, such as sheet metal, to form a cavity defined by the channel and the sheet metal. The second alloy in the form of a powder is placed in the cavity and subjected to heat and pressure to metallurgically weld the first and second alloys and form a composite railroad wheel.
摘要翻译：由至少两种金属合金形成的铁路车轮。在一个实施例中，铁路车轮具有由第一合金形成的主体和由最初为粉末形式的第二合金形成的边缘。在一个示例性实施例中，为了形成双合金轮，车轮的主体以形成在其中的周向通道铸造。身体的周边用诸如金属板的材料包住，以形成由通道和金属板限定的空腔。将粉末形式的第二合金放置在空腔中并经受热和压力以冶金焊接第一和第二合金并形成复合铁路车轮。

摘要： A motor support bearing assembly is provided for a live axle used in locomotives. A wheel is press fit on each end of the axle under high pressure, with a gear secured between the wheels adjacent the pinion end of the axle. The motor support bearing assembly is located between the plain end wheel at the commutator end and the axle gear at the other end, and includes a housing, a tapered roller bearing adjacent the plain end wheel, and another tapered roller bearing adjacent the axle gear. In the motor support bearing assembly process, a master spacer made of hardened metal is placed in a selected space in the assembly. The plain end wheel is pressed onto the axle under high pressure. Axial end play in the motor support bearings is set by applying a spike of additional pressure to the plain end wheel, pressing the bearings together tightly and in some cases pre-loading the bearings. The master spacer is then removed and replaced by a slightly smaller shim, which releases pressure on the bearings and creates end play. The shim can be replaced by a still smaller shim if additional end play is desired. In this manner, and play is reduced significantly. In addition, the pressure with which the assembly is made makes a tighter assembly which lasts longer. Both the reduced end play and the tighter assembly improve performance over time.
摘要翻译：为机车中使用的活动轴提供电机支撑轴承组件。在高压下将轮压配合在轴的每一端，齿轮固定在相邻于车轴的小齿轮端部的轮之间。电动机支撑轴承组件位于换向器端的平端轮与另一端的轴齿轮之间，并且包括壳体，邻近平端轮的圆锥滚子轴承以及邻近轴齿轮的另一圆锥滚子轴承。在马达支撑轴承组装过程中，由硬化金属制成的主间隔件放置在组件中的选定空间中。普通端轮在高压下被压在轴上。电动机支撑轴承中的轴向端部通过向普通端轮施加额外的压力尖峰，将轴承紧紧地压在一起并且在某些情况下预先加载轴承来设定。然后拆下主垫片，并用稍小的垫片代替，这样可以释放轴承上的压力并产生最终的冲击。如果需要额外的最终游戏，垫片可以由更小的垫片代替。以这种方式，并且播放显着减少。此外，组装的压力使得更长的组装更持久。减少的终端播放和更紧密的组合都可以随着时间的推移提高性能。
