Definitions

  • the invention relates to a method and a machine tool for machining wheel tires of a railway wheel set.
  • a machine for machining wheel tires of a railway wheel set by grinding is known, for example, from US Pat. No. 2,754,630.
  • the wheel set is picked up between the center tips of two tailstocks and set in rotation by a friction roller, while the wheel tire is profiled with a grinding tool.
  • two friction rollers are provided which do not engage vertically below the wheel set received between the center points on the circumference of the wheel tire, but laterally therefrom.
  • wheel tires of railroad wheel sets can essentially only be machined by grinding, because for machining, for example by turning or milling, significantly higher cutting forces occur than grinding, which do not allow precise machining of the wheel set without firm support in the machine frame.
  • the machine frame of the known wheelset grinding machine is mounted on runners and is therefore portable.
  • DE 100 25 724 AI discloses a method and machine for machining railway wheels, the machine frame of which is also designed to be portable.
  • the wheel discs or brake discs a railway wheel or wheel set rotatably mounted in bearing housings are detected by a tensioning element which engages at least one bearing housing by pressing the wheel set with a wheel disc on its circumference against support rollers, at least one of which rotates the railway wheel or wheel set while simultaneously a tool works one of the wheel or brake discs.
  • This machine is particularly suitable for machining railway wheels or wheel sets which are installed in the vehicle while they are being machined. As a result of its mobility, the known machine can also be used economically for processing small batch sizes.
  • the object is achieved by two different methods:
  • a tool for machining the wheel tire of at least one of the two wheel disks of the wheel set is first set in the Z direction of the machine,
  • read pattern means the machining of the outer contour of the wheel tire. This editing can be done either Turning, milling or, as is known, done by grinding.
  • the position of the wheelset in relation to the center of the portable machine is determined, for example, by touching a collar or shoulder of the wheelset shaft with a button. Then the back of one or both wheel tires of the two wheel disks of the wheel set is planned with one tool each. With this planning, the AR dimension between the two backs of the wheel tire is also set.
  • AR dimension means the mutual distance between the two wheel disks. The AR dimension is measured from the wheel back to the wheel back of the two wheel tires of a wheel set.
  • the QR dimension is also significant.
  • the QR dimension is the distance from the flank inner flank to
  • Flank inner flank measured at the point of transition from the tread to the flange.
  • Brake disks that may still be on the wheel set are also machined with a tool. It can be useful for editing the It is advantageous if two support and drive rollers are provided for each wheel disc of the wheel set. As a result, the torques to be transmitted per support and drive roller can be kept low, so that no slip occurs between the drive and the wheel tire. In the sense of this arrangement, the two support and drive rollers are provided at a mutual distance from one another approximately perpendicularly below the wheel set accommodated between the center tips. Such a device also allows the wheel set to be placed on the support and drive rollers before it can be picked up between the center tips. This arrangement is particularly advantageous for carrying out the method according to claim 1.
  • the support and drive rollers can be moved in the X direction. In this way, the wheelset set on the rollers can be raised to a height where the wheelset shaft can be received between the center tips.
  • a button is provided which can be moved at least in the Z and X directions.
  • the tool support can also be moved in the Y direction. This extends the possibilities for the constructive arrangement of the tool holder for tools and buttons.
  • the tool support is also equipped with a tool holder, which either allows the holding of processing tools for the wheel tire and / or the brake discs or a button. Provide the same tool for wheel tires and brake discs.
  • a machine tool for machining wheel tires and / or brake discs of railway wheel sets by machining is characterized by
  • At least one support and / or drive roller which is suitable for contacting the wheel tire of at least one of the two wheel disks of the wheel set
  • the common support for the two tailstocks can each consist of a yoke on each tailstock and two tie rods connecting the two yokes, which extend along the machine frame on both sides of the wheel set received between the center points.
  • a support roller is provided which is rotatably mounted in the Z direction and is longitudinally displaceable and is capable of absorbing forces acting in the Z direction. With the help of this support roller, the wheel disc is supported on the outer circumference during the profiling of the wheel tire, so that the wheel disc does not bend under the load of chip removal.
