    摘要： A support ring assembly for a railway axle having a support ring configured to be inserted between a rolling bearing and a collar of the railway axle, the support ring having an annular seat, a surface of a radially inner side wall fitted with a radial clearance over the collar and an end wall that abuts against the collar, an annular insert fitted into the seat by means of an annular shield and having an elastomeric annular element having at least two annular protuberances that engage with the collar, the annular element configured to engage with the collar so as to occupy the radial clearance.

    摘要： 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.

    摘要： A measurement system including: a radial external hole on a cover of a railway axle-box on the side of an edge of the cover facing towards a rolling bearing of the axle-box; a smaller axial hole made on the edge of the cover facing towards a ring of the bearing and opening in the radial hole; a cup-shaped body accommodated in the radial hole; a fork shaped spring integrally carried by a bottom wall of the cup-shaped body, projecting in front of the axial hole; a temperature probe slidingly accommodated within the axial hole and including a tubular element incorporating an electrical temperature sensor and an electric cable protruding from a first end of the tubular element accommodated within the cup-shaped body; and an abutting element removably coupled to the first end to cooperate with the spring, which pushes a second end of the probe out of the axial hole.

    摘要： A railway axle is described of the type in which a rolling element bearing is mounted within a seat defined between two members, a first of which rotates with respect to the second, and is provided, externally of the seat, with a sealing assembly adapted to protect respective rolling bodies of the bearing; an annular element of the sealing assembly is fixed for rotation with the rotating member of the axle and is provided with a plurality of permanently magnetized zones having substantially the same width circumferentially spaced from one another with substantially constant pitch; within the seat and close to the said annular element of the sealing assembly there is further provided a sensor carried by the fixed member of the axle and adapted to be activated by the transit past it of the said magnetized zones to generate a periodic signal having a frequency proportional to the number of these which transit past the sensor in unit time.
