Definitions

  • the present invention relates to a base body for a support disc for the storage of an open-end spinning rotor according to the preamble of the claim 1.
  • open-end spinning rotors are so-called indirect bearings used because the spinning rotors with much more operated at 100,000 revolutions per minute.
  • the indirect camp for the radial mounting of the spinning rotor consist of four support disks, which are arranged in pairs and each pair forms a wedge gap, the area of the rotor shaft end being accommodated in the first wedge gap while the area of the rotor shaft is supported in the other wedge gap that receives the rotor pot of the spinning rotor.
  • Form the support disks So on its peripheral surface the tread on which the spinning rotor its rotor shaft rolls.
  • This tread is made of a plastic, e.g. Polyurethane, or rubber.
  • the tread of a support disc is used for this purpose, for example Injection molding applied to the base body. Due to the ever increasing The speeds of the open-end spinning rotors also become the support disks operated at a higher speed, which leads in particular to the fact that the Tread is more heavily loaded and thus increases the risk that it detaches from the base body of the support disc. To prevent this, are profiles from the prior art on the outer circumference of the support disk base body known, in addition also partially holes be introduced in the axial direction or grooves or notches to better connect the tread to the base plate.
  • This configuration of the peripheral region of the support disk base body requires a high manufacturing effort, for example Holes are always drilled in an additional step have to be, while the base body otherwise, for example is made from a solid material by turning. It is also known Manufacture supporting disc base body by extrusion.
  • the disadvantage of the known support disk base body is that it only with large processing effort in sufficient quality may or may not have sufficient strength, so that mounting problems with the waves that carry them.
  • the object of the present invention is to provide a base body for a support disk propose the inexpensive and with few processing steps can be produced and at the same time has high strength, which allows it to be securely attached to an axis of a bearing.
  • This The object is achieved by a support disk with a base body solved according to the present invention. Because the main body is made by extrusion and one after extrusion Has been subjected to the hardening process, it is achieved that the base body is inexpensive is, and that its shape with sufficient accuracy of fit is producible and also has sufficient strength, which allows it to be stored by means of axes and during operation to keep its shape.
  • the base body is particularly advantageously made of an aluminum alloy, which contains magnesium and silicon, as these are particularly suitable is to be extruded into the desired shape and
  • this alloy can be particularly advantageous after the shape hardened particularly easily and with sufficient strength become.
  • the aluminum alloy contains copper, whereby is achieved that the base body with a particularly high strength can be manufactured.
  • a basic body is particularly favorable here is hardened cold, as this leads to particularly high strength.
  • the base body is warm cured, making it high strength and also low Has brittleness and therefore particularly good usage properties.
  • the base body at least partially has a strength of at least 220 N / mm 2 ensures that it can be reliably supported, for example, via a bore on an axis.
  • a base body with a strength of at least 250 N / mm 2 it is possible to insert an axis into a bore of the base body for storage, which advantageously has a relatively small diameter.
  • the base body is particularly favorable with a strength between 250 N / mm 2 and 350 N / mm 2 , because with such a base body high speeds can be reliably driven without problems with the connection between the base body and the axis supporting it.
  • the base body with the strength according to the invention is particularly favorable equipped at least in the area of his hub. Step in this area the greatest loads, especially by the storage means, so that in Area of the hub the strength is of particular importance.
  • the base body and the hub are formed in one piece, whereby the production is particularly simple and inexpensive.
  • the base body advantageously has a profile on its outer circumference, which is at least partially made by extrusion.
  • the profiling can be formed particularly inexpensively can and at the same time a shaping of the profiling can be made possible can be difficult to manufacture with other manufacturing processes is.
  • Undercuts on the profile can also be advantageous in particular by extrusion.
  • Through training of the base body by means of extrusion is achieved particularly advantageously, that the basic body, except for the processing that may be required the bore, can be made completely finished, which reduces the manufacturing cost lowers. Result from the symmetrical design of the profiling manufacturing advantages and the particular advantage that a subsequent set on the basic body evenly on Basic body can be determined.
  • the design of the profile with a radially arranged outside bell-shaped profile advantageously results in an easy extrusion Profile to be produced radially on the outer circumference of the base body at the same time is particularly cheap for setting a set and above also ensures that when applying a set the material thickness the set or the covering of the support disc, especially when designed with a groove always remains constant.
  • the design of a base body on the outer circumference is particularly favorable has openings in the axial direction caused by extrusion or are produced by stamping. This can be done easily A particularly advantageous base body can be produced on the a set, that is to say a tread, is particularly easily and securely fixed can be. These are openings in particular by punching particularly simple and inexpensive, even in a subsequent machining process, produced.
  • a base body for a Support disc this is provided with markings are produced by means of extrusion or punching. With the help of these markings it is particularly easy to increase the speed of the support disc detect how this is particularly the case in piecing processes known in the prior art is required. By marking, especially if this is designed as an opening through extrusion or punching a simple way is created, the speed to measure the support disc without taking any further measures must be made.
  • Two or three subordinate ones in time are particularly suitable for this purpose Processing stages, because this ensures reliable dimensional accuracy and at the same time solid and inexpensive basic bodies can be produced.
  • the basic body is also reworked by machining be, especially in the area of the hole, so that after extrusion the bore for receiving an axis, in particular, with very narrow Tolerances can be produced.
  • the base body according to the invention between 55 mm and 80 mm in diameter, preferably between 60 mm and 75 mm, it is achieved that the hub on the base body in sufficient size can be produced and in particular that sufficient deformation takes place during extrusion, so that a distortion is largely prevented.
  • this an outer diameter, which is in relation to the diameter of the Bore of the hub is between 1.6 and 2.5, particularly favorable between 1.8 and 2.3. This advantageously ensures that the hub is in position sufficient force is to be exerted when it is pressed onto a shaft, which is a safe Define a support disc with its base body on an axis guaranteed.
  • the advantageous design of the marking as an opening enables save additional components for marking the support disc and thereby train them inexpensively. It is advantageous when used several breakthroughs made sure that these preferably over 180 ° are arranged on the support disc or distributed around its axis.
  • FIG. 1 shows a perspective view of an inventive Base body 1 for a support disc for mounting an open-end spinning rotor.
  • the base body 1 has a hub 2, with a bore 21, in which with the help of a press fit of the base body 1 of a support disc in the operating case is attached to an axis, which in turn in bearings, for example Rolling bearings, is stored.
  • This has on the outer circumference of the base body a profiling 3 with the help of a clothing covering on the base body 1 (Tread) is attached.
  • the profiling is used for example Trim covering applied by injection molding in undercuts 31 of the profiling can intervene, whereby it, in particular in radial Direction, is particularly securely attached to the base body 1.
  • the Base body 1 has an outer diameter G
  • the hub 2 has an outer diameter Diameter N and the bore 21 the diameter B.
  • Figure 2 shows a side view of the base body 1 of Figure 1.
