Definitions

  • the invention relates to a ring spinning machine according to the preamble of claim 1.
  • Angular flange rings have long been known from the patent literature, for example from US Pat. No. 3,159,963.
  • Angular flange rings are used to increase the contact surfaces between the spinning ring and the ring traveler and, with a reduction in the specific surface pressure, also to reduce wear and at the same time to increase the stability of movement of the ring traveler on the spinning ring.
  • a slight curvature of the tread of the spinning ring on the conical inside of the inclined flange of the spinning ring can lead to the ring traveler becoming unstable since it is not forced enough into its stable position with line contact on the tread of the spinning ring. This can also lead to higher wear on the ring traveler and thus also on the spinning ring. If the radius of the spinning ring is at the point of the smallest If the inside diameter is chosen too small, the surface pressure between the spinning ring and ring traveler is considerably higher at this point than in the other areas of the rotor. This also leads to greater wear and tear at the points in question, which further reduces the life of the rotor on the ring spinning machine. This is the case with the known solutions according to the prior art.
  • prior art spinning rings have the disadvantage that the height of the bead in the running section of the spinning ring is chosen to be unnecessarily large.
  • the height measured in the direction of the flange inclination can be more than twice the thickness of the bead, as a result of which the dimensions of the rotor and thus its mass increase.
  • the surface pressure is comparatively high due to the centrifugal force of the rotor for a given wire diameter of the rotor. If a given rotor mass is to be maintained, the wire diameter of the rotor must be chosen so small that the surface pressure between the ring rotor and the spinning ring, again due to the smaller contact surface, becomes so high that inadmissible wear occurs.
  • the spinning ring 1 according to the invention in FIGS. 1 and 2 is mounted in a ring frame 15 of the ring spinning machine.
  • the base section 14 of the spinning ring 1 connected to the ring frame 15 goes up into the so-called inclined flange 11 and this merges into the running section 12 of the spinning ring.
  • the oblique flange 11 resembles a circular truncated cone with generatrixes which are inclined at an angle ⁇ according to FIG. 2 to the vertical.
  • At the top of the ring there is a bead 12 'on the running section 12 of the spinning ring, which also leads the ring traveler 2 which has been placed on the spinning ring 1 to the running surface 13.
  • the tread 13 has a curvature between the points A and B, which can have a constant radius of curvature R2. Above point A, a partial running surface 13 'with the radius of curvature R1 adjoins the running section 12 of the ring.
  • the connecting line C between points A and B forms an angle ⁇ with the vertical, which is preferably 33 ° + -2 °.
  • the ring traveler 2 is shown in FIGS. 1 and 2 not lying against the spinning ring in the meridian plane of the section through the spinning ring 11.
  • the ring traveler 2 consists essentially of an outer rotor leg 21, which surrounds the bead 12 ', and an inner rotor leg 22.
  • the running surface 13 of the spinning ring as described above formed by parts of circular surfaces with the radii R1 and R2, would ideally be parts of hyperboloids with constantly changing radii of curvature in the meridian section. In practice, however, the approximation of a hyperboloid part by a curved surface with a constant radius is sufficient.
  • the inner rotor leg 22 of the ring traveler 2 can run in a straight line between the points A and B. When the ring traveler 2 is inclined on the spinning ring 1 during the rotation, As indicated in Fig.
  • the side of the rotor arm 22 facing the spinning ring lies evenly on the spinning ring in the area between the points A and B, but also above the point A, if the inner contour of the rotor arm 22 at point A is shaped accordingly.
  • the radius R1 on the spinning ring is 1.0 mm, choose 1.2 mm for the corresponding inner radius R3 of the ring traveler.
  • the shape of the outer rotor leg 21 in the periphery of the bead 12 ' is less important for the function of the ring rotor. There must be enough distance between the bead 12 'and the inner contour of the runner leg 21 so that the ring traveler 2 does not touch the outside of the bead 12' during the rotation on the spinning ring 1.
  • Preferred dimensions of the spinning ring 2 in the meridian section are as follows:
  • the underlined values are preferred for ring spinning machines in the yarn number range 5 ... 30tex.
  • the inner diameter D according to Fig. 1 can e.g. be between 36 mm and 40 mm.
  • Fig. 3 shows a partial view of a spinning ring 1 with the ring traveler 2 during the circulation in the circumferential direction according to arrow L.
  • the spinning yarn G above the ring traveler 2 runs as a thread balloon around the spindle 3, is deflected at the top in the ring traveler 2 and runs from here in the direction of the arrow G 'tangentially on the circumference of the spindle 3.
  • the ring traveler 2 is inclined during the circulation on the spinning ring 1 as shown in FIG. 3. The inclination depends on various factors such as the spinning speed, the thread number, the spindle diameter, the thread titer, the frictional relationships between the spinning ring 1 and ring traveler 2 etc.
  • the Ring traveler 2 opposite the spinning ring 1 such that its inner rotor leg 22 on the inside coincides with the generatrix of a hyporboloid, which, as mentioned, partly through the running surface 13 in the area between the points A and B through the curved surface with the radius of curvature R2 in the meridian section is approximated.
  • Fig. 4 is a section along section line IV - IV through the spinning ring 1 in Fig. 3.
  • the forces acting on the ring traveler are shown, namely the centrifugal force F due to the mass of the ring traveler, the component of the ring plane resulting thread force R, the normal force N from the spinning ring 1 on the ring traveler 2, which comes from the surface pressure between the ring traveler 2 and the spinning ring 1 below point A, and the supporting force S, which in the partial running surface 13 'of the spinning ring 1 on the corresponding lot of Runner is transmitted.
  • the contact zone between the spinning ring 1 and the ring traveler 2 is shown by the dashed arrow line Z.
  • Fig. 5 the line of forces for the forces keeping the ring traveler 2 in equilibrium is drawn in solid lines, namely in solid lines for the conditions in a ring spinning machine according to the invention and in dashed lines for a comparable ring spinning machine according to the prior art, such as it is represented, for example, by the aforementioned US Pat. No. 3,159,963.
  • the centrifugal force F ' is considerably greater than the centrifugal force F in an embodiment according to the invention, since the outer rotor leg 21 according to the prior art is considerably longer than that according to the invention.
  • the components R and R 'of the resulting thread forces in the cutting plane are assumed to be the same size.
  • the magnitude of the normal forces N or N ' results from the assumption that the supporting forces S or S' run at the same specific angle for both cases under consideration and close the force plan to the origin of the centrifugal force F or F '. It can be seen from the comparison of the two force plans in FIG.
