Definitions

  • the present invention relates to a method for producing a base body for a support disk for the mounting of an open-end spinning rotor and a base body according to the preamble of claims 1 and 7.
  • Such a body is known from DE 36 15 777 A.
  • indirect bearings For the storage of open-end spinning rotors so-called indirect bearings are used because the spinning rotors are operated at well over 100,000 revolutions per minute.
  • the indirect bearings for radial support of the spinning rotor consist of four support disks, which are arranged in pairs and each pair forms a wedge-shaped gap, wherein in the first wedge-shaped gap, the region of the rotor shaft end is received, while in the other wedge-shaped gap, the region of the rotor shaft is mounted, the Rotortopf the spinning rotor takes up.
  • the support disks thus form on their circumferential surface the running surface on which the spinning rotor rolls with its rotor shaft.
  • This tread consists of a plastic, such as polyurethane, or rubber.
  • the tread of a support disk is applied to the base body, for example, by means of injection molding. Due to the ever-increasing speeds of the open-end spinning rotors and the support disks are operated at a higher speed, which in particular means that the tread is more heavily loaded and thus increases the risk that it detaches from the main body of the support disk. To prevent this, are from the prior art profilings on the outer circumference of the support disk base body known, in addition also partially holes in the axial direction or grooves or notches are introduced to better connect the tread with the support disk base.
  • this embodiment of the peripheral region of the support disk base body requires a high manufacturing cost, since, for example, holes must always be introduced in an additional step, while the main body is otherwise made for example by turning a solid material. It is also known to produce Stauer-inh base body by extrusion.
  • the disadvantage of the known support disk base body is that they can be produced only with great processing effort in sufficient quality or have no sufficient strength, so that there are mounting problems with the shaft carrying them.
  • Object of the present invention is to propose a base for a support disk, which is inexpensive and can be produced with a few processing steps and at the same time has a high strength, which allows him to securely fasten on an axis of a bearing.
  • This object is achieved by a basic body according to the present invention.
  • the fact that the main body is made by extrusion and has been subjected to a hardening process after extrusion, it is achieved that the body is inexpensive, and that its shape with sufficient fitting accuracy can be produced and also has sufficient strength that it deafened him to store by means of axes and to remain dimensionally stable during operation.
  • the main body consists of an aluminum alloy containing magnesium and silicon, since this is particularly well suited to be brought into the desired shape by extrusion and, moreover, this alloy is made particularly simple and with sufficient strength following the shaping.
  • the aluminum alloy contains copper, which ensures that the base body can be produced with a particularly high strength.
  • a base body which has hardened cold is particularly favorable since this leads to particularly high strength.
  • the base body is thermally cured, whereby it has a high strength and, moreover, a low brittleness and thus therefore very good service properties.
  • the body at least partially has a strength of at least 220 N / mm 2 , it is certainly achieved that it can be stored reliably for example via a bore on an axis.
  • a base body with a strength of at least 250 N / mm 2
  • an axle for storage in a bore of the body which advantageously has a relatively small diameter.
  • the body is configured with a strength between 250 N / mm 2 and 350 N / mm 2 , because with such a body reliably high speeds can be driven without problems occur at the connection between the base body and the axis stored him.
  • the base body is equipped with the strength according to the invention at least in the region of its hub. In this area, the greatest loads occur, in particular by the bearing means, so that in the region of the hub, the strength is of particular importance.
  • the main body and hub are integrally formed, whereby the production is particularly simple and inexpensive.
  • the main body has on its outer circumference a profiling, which is at least partially made by extrusion. It is thereby achieved that the profiling can be made particularly cost-effective and at the same time a shaping of the profiling can be made possible, which are difficult to produce with other manufacturing processes is.
  • the undercut is realized at the profiling at least partially by extrusion. Due to the design of the base body by means of extrusion it is achieved that the basic body, except for the possibly required machining of the bore, can be produced completely finished, which lowers the production costs.
  • the symmetrical design of the profiling results in manufacturing advantages and the particular advantage that a subsequent applied to the body clothing can be set uniformly on the body.
  • the configuration of the profiling with a radially outwardly arranged bell-shaped profile advantageously results in a profile to be produced by extrusion radially on the outer periphery of the body, which is also particularly favorable for fixing a garnish and beyond ensures that when applying a set the material thickness of the clothing or the lining of the support disk, in particular in the embodiment of the lining with a groove always remains constant.
  • a base body which has openings on the outer circumference in the axial direction, which are produced by extrusion or punching.
  • a particularly advantageous basic body can be produced in a simple manner, on which a set, that is to say a tread, can be determined in a particularly simple and secure manner.
  • punching these openings are particularly simple and inexpensive, even in a subsequent machining process, produced.
  • a base body for a support disk this is provided with markings which are produced by extrusion or stamping.
  • markings are produced by extrusion or stamping.
  • it is particularly easy to detect the speed of the support disk as in particular known in the prior art piecing is required.
  • marking especially if this is formed as an opening, which was produced by extrusion or stamping, a simple way is provided to measure the speed of the support disk, without having to be made to this further action.
  • the basic body according to the invention is inexpensive and repeatable to produce that by several, berspielmik each other in time, downstream processing stages, consisting of extrusion, produced.
  • the base body can be additionally refinished by machining, in particular in the region of the bore, so that after the extrusion, the bore for receiving an axis, in particular, can be produced with very narrow tolerances.
  • the basic 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 can be made on the body in a sufficiently large size and in particular that takes place during extrusion sufficient deformation , so that a delay is largely prevented.
  • the main body of this has an outer diameter which is in relation to the diameter of the bore of the hub between 1.6 and 2.5, particularly favorably between 1.8 and 2.3. This advantageously ensures that the hub is able to exert sufficient force when pressing on a shaft that ensures a secure fixing a support disk with its base on an axis.
  • the advantageous embodiment of the marking as an opening allows additional component to save a mark on the support disk and thereby form this cost.
  • FIG. 1 shows a perspective view of a basic body 1 according to the invention for a support disk for mounting an open-end spinning rotor.
  • the base body 1 has a hub 2, with a bore 21 into which by means of a press fit of the base body 1 of a support plate is fixed in operation on an axis, which in turn is stored in bearings, such as bearings.
  • On the outer circumference of the body this has a profiling 3 with their help on the body 1 a Garniturbelag (Tread) is attached.
  • the profiling serves to ensure that the applied for example by means of injection Garniturbelag can engage in undercuts 31 of the profiling, whereby he, especially in the radial direction, particularly secure on the base body 1 is attached.
  • the main body 1 has an outer diameter G
  • the hub 2 has an outer diameter N
  • the bore 21 has the diameter B.
  • Figure 2 shows a side view of the main body 1 of Figure 1.
  • the hub 2 is arranged, wherein the base body 1 merges into the profiling 3, which is formed on the outer periphery 11 of the base body 1.
  • FIG. 3 shows the section BB of Figure 2 of the base body according to the invention 1.
  • the hub 2 has around the left side of the bore 21 has a smaller outer diameter than around the right side of the bore 21.
  • the profiling 3 is formed, which is designed symmetrically. It thus has on its left and right sides each an undercut 31, viewed in the radial direction, and arranged on the outer circumference bell-shaped profile 32.
  • the main body 1 of Figure 3 has been prepared by two temporally successive processing stages. In this case, first of all the blank 4 of FIG. 5 was converted into the shape of FIG. 4 by extrusion using an extrusion press tool. Subsequently, the precursor 41 of the main body 1 by a further flow process in which the radial profiling was formed, reshaped. In particular, the bell-shaped profile 32 was formed on the outer circumference 11.
  • FIG. 6 shows a side view of a configured main body 1 according to the invention, wherein the profiling 3, which is approximately configured like that of FIG. 4, also has apertures 5 extending in the axial direction which have been punched out.
  • the openings 5 can be configured differently, with different configurations are not normally carried out on a base body 1. It is exceptionally the case in Figure 6 to represent different openings 5 can. These are formed, for example, as open triangular openings 51 on the outer circumference of the profiling 3, or in the form of substantially circular apertures 52 also open on the outer circumference 11.
  • the perforations 5, 51, 52 can also be produced by extrusion, for example during the formation of the radial Profiling 3 on the outer circumference.
  • Figure 7 shows an inventively designed base body 1, which is provided with markings 6, which are formed as openings 61 in the base body (1). Uniformly over the base body 1 while four apertures 61, each offset by 90 °, arranged.
  • the markers 6 are arranged on the base body 1 in the radial direction between the hub 2 and the undercut 31.
  • the basic body 1 shown in FIGS. 1, 6 and 7 has additionally undergone a hardening process after the extrusion molding according to the invention.
  • heat curing has been advantageously used.
