Definitions

  • Rolling unit for deep rolling the wheel treads of rail vehicles
  • the invention relates to a rolling unit for machining the wheel treads of wheelsets for rail vehicles, wherein the roller unit has at least one deep rolling with which the wheel tread to be machined after manufacture of the wheel set in the new condition or at a later time after reprofiling to increase the life of the wheel treads Deep-rolling is subjected.
  • Rail vehicles are usually equipped with wheelsets, with which a constant contact between the vehicle and track body and thus safe support and guidance of the respective rail vehicle is guaranteed.
  • the wheelsets are directly stressed by this rolling contact and are safety-relevant for a controlled vehicle movement.
  • the geometry of the wheel tread determines the running of the vehicles. In the maintenance of rail vehicles, the wheelset is therefore of particular importance.
  • the high demands on reliability and quality require regular monitoring and assessment of the current state of the component and the available stock of wear.
  • the wheel-rail system is subject during driving by the permanent sliding and rolling movements different wear mechanisms.
  • the consequent deformation of the Radlauf vomprofils is in addition to an acoustic source of interference for passengers and the environment also a risk of material failure for the wheelset and the surrounding components, such as wheel bearings and chassis. This problem should be largely avoided by the so-called reprofiling the Radlauf vomprofils.
  • contours are realized that take into account the natural wear between the wheel and rail. Ideally, the contours should not or only slightly change during operation of the rail vehicles.
  • the resulting wear due to material removal on the wheel and rail depends primarily on the friction power in the contact zone and the material combination. Basically, a distinction is made between tread and wheel flange wear. By combining these two wear profiles results in a possible wear profile, which is to reprofile.
  • Such re-profiling can be carried out with wheel set processing machines, which are known in various variants, for example, as underfloor or above-floor design as well as in flatbed and gantry design. With the wheel set processing machines, the wheel treads are machined using machining methods, preferably by turning, so that these machines are also referred to as wheelset lathes.
  • the deep rolling of the surface is a mechanical minimally invasive deformation of the component edge layer.
  • suitable rolling elements are defined defined under contact pressure over the surface of the finished component.
  • the direct component contact area becomes plastic and the adjacent contact area is elastically deformed.
  • small notches are leveled or the material is solidified in the plastically deformed volume.
  • DE 808 197 describes a roller for deep rolling of stub axles on railway wheel sets.
  • the working surface of this deep rolling roller consists of a cylindrical base body.
  • the axis of the deep rolling roller runs obliquely to the axis of the steering knuckle and generates on the surface to be machined an elongated teardrop-shaped impression. Consequently, residual stresses are introduced into the surface of the steering knuckle in the region of the impression by the deep rolling, whereby the occurrence of new cracks should be avoided or existing cracks should be brought to a standstill.
  • an increase in the service life of a wheel set is achieved by the deep rolling.
  • DE 843 822 Another approach to deep rolling cylindrical shafts is known from DE 843 822.
  • This device has one or more fixed rollers.
  • each deep rolling roller is mounted in a pivotable carrier whose pivot axis is perpendicular to the feed movement of the deep rolling roller and approximately perpendicular to the wheelset shaft.
  • the object of the invention is to provide a rolling unit can be rolled with the wheel treads using fixed rollers in the feed process.
  • the roller unit has a base body on which a support arm is arranged perpendicular to the base on which a receptacle is supported, which is fixed in position by a thread in the support arm and on which an angular contact ball bearing is arranged, on which a deep rolling is supported, which has at least two different rolling radii.
  • a modified embodiment provides that the rolling unit has a base body on which a first support arm and a second support arm are supported, each perpendicular to the base of the body and parallel to each other, wherein on the support arms a receiving pin is supported, the two-sided and over at least one thread in the support arms is fixed in position and on which an axial-radial bearing is arranged, on which a deep-rolling roller is supported, which has two equal or different rolling radii,
  • Fig. 1 shows a first embodiment of the rolling unit in a perspective view
  • Fig. 3 shows a detail of a deep rolling roller with representation of different radii
  • Fig. 4 shows a second embodiment of the rolling unit in a perspective view
  • Fig. 6 shows the rolling course along the wheel tread and flange radius
  • the rolling unit shown in Fig. 1 and Fig. 2 consists of a base body 1, on which a support arm 2 is arranged perpendicular thereto.
  • the main body 1 and the support arm 2 act functionally as a holding device, on which a deep rolling roller 3 is supported.
  • the cylindrical deep rolling roller 3 has at least two different rolling radii R1 and R2, which can be seen in particular from FIG. Alternatively, other rolling radii R3 ... R n can be provided.
  • the rolling radii R1 ... R n together form a teardrop shaped roll surface in order to produce optimal surface pressures on the wheel tread during the deep rolling.
  • the rolling radii are adapted to the wheel tread geometry to be rolled.
  • the rolling radii in the front region R1 are between 1 mm and 12 mm and in the rear region R2 between 1 mm and 500 mm.
  • the deep rolling roller 3 may be made of hardened steel or carbide and has a roll diameter between 20 mm and 200 mm.
  • This bearing is preferably realized with a rolling bearing, because rolling bearings are very adaptable in terms of their application by various forms. Rolling bearings are loadable, they endure high speeds and are also partially maintenance-free, provided, for example, with lifetime lubrication and lip seal are equipped.
  • a double-row angular contact ball bearing 4 is preferably used as the rolling bearing. Such an angular contact ball bearing 4 allows a good compromise in terms of space and load capacity.
  • an embodiment with a lifetime lubrication and with both sides attached sealing lips is proposed.
  • other variants are possible, such as deep groove ball bearings, cylindrical roller bearings or combined axial-radial bearings.
  • a support 5 supported on the support arm 2 is intended to guide the loads during the deep rolling of the deep rolling roller 3 via the angular contact ball bearing 4 into the holding device. Due to the design of the angular contact ball bearing 4, this recording is performed cylindrically.
  • the receptacle 5 is fixed on one side via a thread in the support arm 2 of the holding device. For a particularly precise positional fixing an annular flange is formed on the receptacle 5, which is effective as a threaded stop and simultaneously secures the recording 5 with the support arm 2 of the holding device against rotation via a dowel pin 6.
  • the bearing assembly has in addition to the clamping pin 6 other components, such as circlip or nut, which are not provided with reference numerals.
  • the consisting of support arm 2 and body 1 holding device forms functionally considered a coupling unit between the deep rolling roller 3 and processing machine.
  • the holding device can be used instead of the rotary cutting head available for turning machining or adaptively coupled with the processing machine next to the rotary cutting head.
  • the feed travel paths of the rotary cutting head of the processing machine make it possible to descend the wheel tread pattern with the deep rolling roller 3 of the rolling unit.
  • the wheel profile can be rolled over the tread to the flange tip, so that the construction for related operations is very well suited.
  • roller geometry has a periphery adapted in such a way that hereby the entire wheel profile - running surface, wheel flange radius and wheel flange surface - can be processed in only one step.
  • This rolling unit likewise consists of a base body 1, on which a first supporting arm 2 arranged perpendicular thereto is arranged. Furthermore, here a second support arm 7 is provided, which is also supported on the base body 1 and parallel to the first support arm 2.
  • the main body 1 and the two support arms 2 and 7 functionally act as a holding device on which a deep rolling roller 3 is supported.
  • the rolling radii R1 and R2 of the cylindrical deep rolling roller 3 may be the same, but they may be different. These rolling radii R1 and R2 are adapted to the Radlauf vomgeometrie to be rolled and here are between 3 mm and 30 mm.
  • the deep rolling roller 3 may be made of hardened steel or carbide and has a roll diameter between 20 mm and 200 mm.
  • a combined axial / radial bearing 8-9 is preferably used in this variant.
  • other variants are possible, such as deep groove ball bearings, cylindrical roller bearings or plain bearings.
  • a supported on the support arms 2 and 7 receiving bolt 5 is intended to direct the loads during deep rolling of the deep rolling roller 3 via the axial-radial bearings 8-9 in the holding device. Due to the design of the bearing, this recording is performed cylindrically.
  • the receiving bolt 5 is fixed on both sides via a thread in the holding device. There are two flanges provided to accommodate the axial components of the axial-radial bearing 8-9 and dissipate axial forces in the fixture.
  • base body 1 and support arms 2 and 7 holding device is functionally considered the coupling unit between the deep rolling roller 3 and processing machine.
  • This fixture should be replaced instead of existing for turning rotary cutting head or adaptively coupled next to the rotary cutting head with the processing machine for the wheel treads.
  • Fig. 6 shows an example of the rolling course along the entire profile in six positions a) to f).
  • the feed direction of the deep rolling roller 3 runs from right to left.
  • roller unit described is suitable in both embodiments both for underfloor and for above-floor wheelset lathes in flatbed and gantry design.
