摘要： A roller assembly for an undercarriage of a work machine has a roller rim having (i) central passage, and (ii) an inwardly extending annular flange defined therein. The inwardly extending annular flange extends into the central passage so as to define a flange opening having a first diameter. The roller assembly also has a roller shaft having a first end portion which is positioned outside of the central passage of the roller rim and a second end portion which is positioned within the central passage of the roller rim. The second end portion of the roller shaft has an outwardly extending annular flange secured thereto. The outwardly extending annular flange of the roller shaft has a second diameter. The second diameter is greater than the first diameter. An undercarriage for a work machine is also disclosed.

摘要： A wheel assembly for a rail vehicle that travels on a rail; the wheel assembly comprising a wheel axle, a wheel and a derail guard. The wheel is mounted for rotation about an axis defined by the wheel axle. The wheel has an annular flange on one side thereof, which is adjacent one side of the rail. The derail guard includes a connecting portion, mounted for pivotal movement about the axis of the wheel axle, and a guard portion, depending and hanging pendulously from the connecting portion. The guard portion is disposed on a side of the rail opposite the one side and extends downwardly under the force of gravity. The guard portion is pivotally movable in a direction generally parallel to the rail when contacted by an obstacle adjacent the opposite side of the rail.

摘要： The present invention relates to a method of manufacturing an all metal, single or dual, flanged composite railroad wheel for rollingly engaging a metal rail. A unitary metal railroad wheel having at least one radially extending wheel flange, for intermittently engaging the side surface of the rail, is provided with a metallic inlaid material having a coefficient of friction lower than the coefficient of friction of the wheel's main body. The inlaid low friction material forms an annular band circumscribing the inside surface of the wheel's radially extending flange.

摘要： A roller assembly for an undercarriage of a work machine has a roller rim having central passage defined therein. The roller assembly also has a roller shaft positioned in the central passage of the roller rim. Moreover, the roller assembly has a retainer secured to the roller rim so as to retain the roller shaft in the central passage. The retainer is prepared by a process including the steps of (i) arranging a first type of metal powder in a first predetermined location, (ii) arranging a second type of metal powder in a second predetermined location, the second type of metal powder being different than the first type of metal powder, and (iii) sintering both the first type of metal powder and the second type of metal powder. A method of manufacturing a roller assembly of an undercarriage assembly is also disclosed.

摘要： A wheel comprises a main body, a tread making a contact with a top face of the rail head of a rail, and a flange. At least at a portion of the wheel tread which is in contact with the rail, there is provided a tread-forming component formed of a ceramic-particle-dispersion reinforced aluminum composite material, which has ceramic particles mixed in an aluminum alloy. The tread-forming component is formed in a ring shape, fitted into a tread-forming component receiving portion and fixed to the main body by a fixing member.

摘要： Endless rubber track laying machines are provided with a pair of track laying assemblies positioned on opposite sides of the work machine. Each track laying assembly includes an endless rubber belt entrained around a drive wheel, an idler wheel, and a plurality of supporting mid-rollers. The present supporting mid-roller includes a heat shield that is positioned between individual roller segments and guide blocks positioned on the inner surface of the endless rubber belt. With the heat shield in this position, heat generated from the guide blocks contacting the individual roller segments is dissipated, thereby increasing the life of the individual mid-roller components.

摘要： A roller assembly for an undercarriage of a work machine is configurable in either a first roller configuration or a second roller configuration. The roller assembly has a roller shaft and a roller hub journalled for rotation about the roller shaft. A first roller rim having a first outer diameter is secured to the roller hub when the roller assembly is configured in the first roller configuration. A second roller rim having a second outer diameter is secured to the roller hub when the roller assembly is configured in the second roller configuration. The first outer diameter is greater than the second outer diameter. A method of manufacturing a roller assembly of an undercarriage assembly of a work machine is also disclosed.
