Definitions

  • the invention relates to a covering system for axles of rail vehicles according to the preamble of claim 1 and a generator system with such a cover system.
  • DE 10 2006 035 703 A1 When attaching a device to the end cap, such as a device for monitoring an operating size of a wheelset bearing according to DE 10 2006 035 703 A1, an additional cover for covering the device is needed.
  • the cover from DE 10 2006 035 703 A1 essentially covers the wheel distal end of the wheel axle and is releasably connected by screws to the rest of the housing. Further possibilities to cover an end of the wheelset shaft are disclosed in DE 10 2009 050 145 A1 or in DE 199 34 307 A1.
  • Object of the present invention is to show an improved and advanced cover system with a simpler installation.
  • the cover system according to the invention for wheelset shafts of rail vehicles has a cover and a wheelset bearing unit.
  • the wheelset bearing unit has a bearing housing and a wheelset bearing for supporting a wheelset shaft.
  • the axle box has an end cap, the lid enclosing the end cap of the axle box.
  • the covering system according to the invention is characterized by a centering device for aligning the lid with respect to the bearing housing, wherein the centering device has at least one groove on the front side of the bearing housing facing the dekel.
  • the bearing housing is often referred to as an adapter, which is connected to the bogie of the rail vehicle.
  • the groove is circular arc-shaped.
  • the circular arc-shaped groove is formed coaxially with the axle box.
  • the groove preferably extends over the entire width of the end face of the bearing housing.
  • the width of the bearing housing is measured, starting from the axis of rotation of the bearing housing, in the radial direction.
  • the cover has at least one elevation aligned with the bearing housing, which engages in the groove of the bearing housing.
  • the survey extends for example over the entire length of the groove.
  • the survey extends in sections over the length of the groove.
  • a plurality of elevations may be formed on the lid, wherein the elevations engages in a groove or each elevation in a groove.
  • the depth of the groove in the bearing housing measured in the axial direction, starting from the axis of rotation of the wheel set bearing, greater than the depth of the elevation of the lid. This ensures that the end face of the bearing housing with the end face of the lid rests flat and no unwanted air gap between the bearing housing and lid is formed.
  • the lid covers a device, in particular a generator unit. This means that axially adjacent to the end cap of the wheelset bearing a generator unit is arranged, which is enclosed by the lid.
  • the generator system according to the invention for rail vehicles has a generator unit and the cover system described above.
  • the generator unit is arranged in the cover of the cover system.
  • the generator unit comprises a stator and a rotor, wherein the rotor is coupled to the end cap of the wheelset bearing and the stator is coupled to the cover of the covering system.
  • the generator unit is designed as a pancake generator.

  • FIG. 4 shows the lid of FIG. 1 in a perspective rear view
  • FIG. 5 shows the covering system from FIG. 1 in a side view
  • the wheelset bearing unit 3 has a bearing housing 4, often also called adapter, and a wheel bearing 5 on.
  • the wheelset bearing 5 comprises a bearing inner ring 6, a bearing outer ring 7, a plurality between the two bearing rings 6, 7 arranged Wälzköper 8 and a non-rotatably connected to the Radsatzwelle end cap 9, which terminates axially, starting from the axis of rotation of the Radsatzlagers 5, the Radsatzlager 5.
  • the bearing housing 4 is fixedly connected to a bogie, not shown here, of a rail vehicle and shown in FIG.
  • a circular arc-shaped groove 11 is formed, which extends over the entire width B of the end face 10 of the bearing housing. 4 extends.
  • the circular arc shape of the groove 11 in the bearing housing 4 is formed coaxially with the axle 5.
  • holes 12 on the end face 10 of the bearing housing 4 starting from the axis of rotation of the wheelset bearing 5, radially arranged above the groove 11 in a circular arc.
  • the holes 12 are formed identically and arranged symmetrically to the radial center plane of the bearing housing 4.
