    摘要: In one aspect, a method of monitoring a mobile railway asset is provided including detecting a strain of a component of a mobile railway asset and gathering data associated with a vibration of the mobile railway asset. The method includes comparing the strain of the component and the data associated with the vibration of the mobile railway asset. The method includes determining a load state of the mobile railway asset based at least in part on the comparison of the strain of the component and the data associated with the vibration of the mobile railway asset.

    摘要: A threaded fastener includes a nut forming a threaded center hole that defines a rotational axis. The threaded fastener also includes a plurality of spring plungers affixed to the nut, each having a shaft that is aligned parallel to the rotational axis. The threaded fastener also includes a positioner forming (i) an unthreaded center hole that is coaxial with the threaded center hole and (ii) a plurality of recesses facing the spring plungers. As the nut is torqued against the positioner on a threaded spindle, the spring plungers repeatedly engage and disengage the recesses as the nut rotates with respect to the positioner. The recesses are shaped such that positioner converts the applied torque into a linear force that compresses the spring plungers, thereby locking the threads of the nut against the threads of the spindle.

    摘要: A truck assembly for a rail vehicle includes at least one side frame including at least one lightener hole. At least one strain gage is disposed within the lightener hole(s). The strain gage(s) is configured to detect forces exerted into or onto the truck assembly. A method of detecting forces exerted into or onto a truck assembly of a rail vehicle includes disposing at least one strain gage within at least one lightener hole of at least one side frame of a truck assembly of the rail vehicle, and detecting the forces by the strain gage(s).

    摘要: In one aspect, a seal case is provided for a roller bearing assembly having a central axis. The seal case includes an annular first end section including a rim configured to engage an outer ring, an intermediate section including a radial wall extending inwardly from the first end section and an axial wall extending axially away from the radial wall and the first end section, and an annular second end section extending radially inward from the axial wall of the intermediate section. The seal case further includes an insert of the first end section made of a first material. The first end section and the radial wall of the intermediate section include a second material joined to the insert. The first material of the insert may be selected to provide improved durability and/or to resist expansion and contraction of the first end section caused by changes in temperature.

    摘要: A method for manufacturing a ring includes clamping a first region of a metal sheet against a mandrel, and, while the first region of the metal sheet is clamped against the mandrel, bending the metal sheet around the mandrel to join opposite end faces of the metal sheet and form the ring shaped to the mandrel. A system for manufacturing a ring from a metal sheet includes (a) a mandrel having a ring-shaped surface, (b) a clamp facing the ring-shaped surface and configured to clamp a first region of a metal sheet to the mandrel, and (c) a plurality of dies configured to bend the metal sheet around the mandrel, while the clamp clamps the first region to the mandrel, to join opposite end faces of the metal sheet and form a ring shaped to the ring-shaped surface.

    摘要: A force analysis system and method include a truck assembly that is configured to travel along a track having rails. The truck assembly includes a first side frame, a second side frame, a bolster extending between the first side frame and the second side frame, a first wheel set coupled to the first side frame and the second side frame, a second wheel set coupled to the first side frame and the second side frame, and one or more load cells disposed within the first side frame and/or the second side frame. The load cell(s) are configured to detect forces exerted in relation to the first side frame, the second side frame, and/or the bolster.

    摘要: A system for polishing a cylindrical lip-seal surface includes a spin platter, a polisher having an abrasive surface, and a fixture. The spin platter rotates about a rotation axis to spin a workpiece, shaped as a hollow cylinder, about a cylinder axis of the hollow cylinder. The fixture holds the polisher against an outward-facing cylindrical surface of the hollow cylinder to polish the cylindrical surface with the abrasive surface while the workpiece is spun by the spin platter. A method for polishing a cylindrical lip-seal surface includes spinning, with a spin platter, a workpiece shaped as a hollow cylinder about a first cylinder axis of the cylinder. The method also includes holding, during the spinning, a polisher having an abrasive surface against an outward-facing cylindrical surface of the hollow cylinder to polish the cylindrical surface.
