Definitions

  • a flanged wheel and axle assembly of the type having a bearing enclosed against a collar on the axle by a pressure plate system is provided with two pressure plates, one mounted axially behind the other, the plates being in mutual contact only in a central zone, the plate closest to the wheel resting directly or indirectly against the bearing structure, and the second plate being drawn towards the end of the axle by drawing means extending through the first plate.
  • a sleeve preferably is provided on the axle between the pressure plate system and the bearing structure; the bearing structure preferably comprises spaced cylindrical and adjustable bearing; the drawing means preferably comprises three or more bolts positioned symmetrically about the central zone of contact; and
  • the assembly forms part of a railway car subjected to high loads.
  • This invention relates to a structure comprising a shaft or axle and a flanged wheel rotatably supported thereon, particularly a railwheel for extremely high loads per shaft, in which a bearing structure of the wheel is enclosed against a collar on the shaft or axle by a pressure plate system secured to the end face of the shaft or axle.
  • a bearing structure of the wheel is enclosed against a collar on the shaft or axle by a pressure plate system secured to the end face of the shaft or axle.
  • the weight to be taken up is usually transitted to the axles or shafts in zones outboard of the wheels.
  • the shafts oraxles are extended to zones past the outer face of the wheel. This gives a problem how to enclose and keep in place the wheel and the hearing from the free end of the shaft or axle. It would be possible to mount a sleeve over the end of the shaft or axle between the wheel and the end face and to enclose and keep in place this sleeve by the pressure plate system, which sleeve in its turn keeps the wheel and the bearing in the correct position.
  • This invention aims at obtaining a structure in which this danger does not arise.
  • the structure according to the invention aims at obtaining a more uniform loading and stressing of the pressure plate system.
  • the two pressure plates can more or less tilt (turn or wobble) with respect to each other about the point or small zone of contact in the central part.
  • the non-uniformity of the deformation of the axle end and of the sleeve are restricted to minimum values. It has appeared that this is obtainable by a good choice and mutual positioning of the bearings, by which the wheel is supported on the axle, or shaft.
  • a structure is preferable in which the wheel is rotatable around the shaft by means of a first and a second bearing, the first bearing being a spherical or other adjustable roll bearing, positioned in the plane through the rim of the wheel, the second bearing being a cylindrical roll bearing at a distance from the fist bearing.
  • This choice and positioning of the bearings moreover has the advantage that the forces in the bearings may be calculated accurately, the calculated horizontal forces on the wheel being taken up by the spherical roll bearing and the calculated vertical forces being taken up by both bearings simultaneously. Thanks to this possibility to calculate the bearings exactly it is also possible to choose bearings having the same efficient life time during operation of the railroad car.
  • FIG. 1 shows the structure in axial section
  • reference numeral 1 indicates a rail wheel in axial section.
  • This flanged wheel is rotatable about shaft or axle 2, which is provided with collar or shoulder 3 spaced from and facing the outboard end of the shaft 2.
  • an antifriction bearing assembly outboard of the shoulder 3 and comprising a spherical roll bearing 5, a cylindrical roll bearing 6 and two distance keeping (positioning) rings 7 and 8.
  • the spherical roll bearing is positioned or centered about in the plane which is perpendicular to the axis and goes through the rim of wheel 1 where this contacts the rail.
  • the inner rings of the bearings 5 and 6 are separated by a ring 7 and the outer rings of these bearings by ring 8.
  • the bearings 6 and 5 lie inboard and outboard of the plane through the flange of the wheel, respectively, in the form shown.
  • the upper structure of the railroad carriage is mounted on said sleeve in such a way that the weight of this upper structure with the load of the car is transmitted through sleeve 15 onto axle end 14.
  • This is diagrammatically shown by an arrow P giving the concerning force in FIG. 1.
  • Sleeve 15 is enclosed and kept in position in contact with wheel 1 by means of a pressure plate system or means l6, 17, 18.
  • This pressure plate system consists of two plates 16 and 17 and three bolts 18.
  • Pressure plate 16 is in contact with the edge of sleeve 15 by a collar-shaped edge and is spaced somewhat from the outboard end of the axle 14, as shown.
  • plate 16 has a protruding part at 19, pointing outwardly and being positioned centrally of the plate.
  • a pressure plate 17 In contact with this protruding part is a pressure plate 17.
  • this plate 17 is drawn towards the axle end 14, for which purpose the end face of this end is provided with screw-threaded holes.
  • Bolts 18 thereto extend through holes 20 in pressure plate 16, which holes 20 are of such a diameter that the bolts 18 pass therethrough with considerable clearance.
  • FIG. 2 the pressure plate 17 with bolts 18 is shown and it appears therefrom that these three bolts are positioned on the comers of a geometrical figure being an equilateral triangle symmetrically with respect to the axis of the system.
  • An improved car wheel structure for supporting heavy load said structure being of the type comprising a. a shaft or axle having an outboard end and a shoulder spaced from and facing said outboard end,
  • said anti-friction bearing assembly comprises first and second anti-friction bearings, the first bearing being a spherical bearing positioned in the plane through the rim of the wheel, and the second being a cylindrical roller bearing at a distance from said first bearing.
