Definitions

  • the invention relates to a device for the radially movable fastening of a spindle bearing housing of a spinning or twisting spindle to a spindle bench according to the preamble of patent claim 1.
  • the elastic element is an essentially annular layer spring with an elastomeric spring body.
  • This layer spring surrounds the spindle bearing housing with play and is clamped between a plate anchored on the top of the spindle bank and the spindle bearing housing with play surrounding it and an annular flange sleeve screwed onto the spindle bearing housing itself.
  • the spindle bearing housing penetrates with play a bore formed in the spindle bank and a nut having a shoulder is screwed onto its part, which is provided under the spindle bank and is provided with an external thread.
  • This compression spring is intended to pre-compress the layer spring in the axial direction and thus inhibit the axial mobility of the spindle bearing housing in an adjustable manner more than its radial mobility.
  • the belt-driven whorl that sits on the spindle which in turn is mounted in bearings arranged in the spindle bearing housing, acts on the one-sided tensile force of the drive belt, then the layer spring is additionally loaded on one side with pressure, with the result that the entire spindle bearing housing is affected the spindle bank assumes an inclined position, which is at least undesirable given the supercritical speeds at which the spindle is driven and the unavoidable unbalance of the package sitting on the spindle.
  • the elastic element which also consists of an elastomer, has the shape of a thick-walled, hollow, upwardly diverging truncated cone, the outer surface of which is vulcanized directly onto the opposite-shaped inside of an annular element which is screwed onto the spindle bench, while the inner surface of which is vulcanized is vulcanized on the outer surface of a sleeve clamped on the spindle bearing housing.
  • the storage device known from CH-PS 528.028 should also be mentioned, for which essentially the same applies as for the device according to CH-PS 509.430.
  • the elastic element is not a layer spring, but a rubber ring, which is arranged below the spindle bench and with its lower flat side on the upper side of the lower end flange of a sleeve firmly clamped to the spindle bench and on its upper flat side rests on an inwardly projecting end flange of a further housing part screwed onto the spindle bearing housing and overlapping the rubber ring.
  • the wreath of the flexible spring bars together with the mounting sleeves thus forms a kind of «spatial parallelogram», which practically only allows the other mounting sleeve to be displaced at right angles to its axis.
  • this other mounting sleeve is firmly connected to the spindle bearing housing, this can only be deflected radially against the action of the spiral spring bars without inclination.
  • a spindle bank 11 In the device 10 shown in FIG. 1, part of a spindle bank 11 can be seen in section, which is part of a spinning or twisting machine with a plurality of identical spindles.
  • the spindle bank 11 has a through bore 12 for each spindle.
  • the spindle consists of a spindle bearing housing 13, in which a bearing sleeve (not shown) is arranged.
  • a spindle shaft 14 extends into this bearing sleeve and is rotatably supported there as a rule by means of a neck bearing 15 and a foot bearing 16 (indicated by dashed lines in FIG.
  • the spindle bearing housing 13 is fastened to the spindle bench 11 only via the spring-elastic element designated by the reference number 19.
  • this spring-elastic element has a ring of four spiral spring bars (20) which (undeflected) run parallel to the axis 21 of the spindle bearing housing 13 and are arranged at regular angular intervals from one another.
  • These spiral spring bars 20 have a rectangular cross section (FIG. 3), the narrow sides of which are directed approximately radially.
  • the bending spring rods 20 start at their upper end from a mounting sleeve 22 with a flange 23 which is screwed onto the top of the spindle bench 11 by means of bolts 24.
  • the spiral spring bars 20 then extend with radial play downward both with respect to the inner wall of the bore 12 (gap 24 ') and with respect to the outer wall of the spindle bearing housing 13 (gap 25), in order to then pass into another holding sleeve 26 in which the lower end of the spindle bearing housing 13 in the press fit, optionally with the aid of further fastening means, for example an adhesive, stuck.
  • the bending spring bars 20 are made in one piece with the mounting sleeves 22, 26, the bending spring bars 20 having an increasing cross section and thus increasing rigidity in their transition regions into the mounting sleeve 22, 26.
  • the lower mounting sleeve 26, which is firmly connected to the spindle bearing housing 13, can be moved transversely to the axis 21, but it is not tilted in any way, because the spiral spring bars 20 can only be bent out, while their possible expansion is negligible in comparison to the extent of the bending is.
  • the extent to which the spindle bearing housing 13 can be moved radially and parallel to itself is essentially given by the width of the gap 25.
  • the one-piece element 19 can be easily manufactured. Either this is done by machining, in order to form the flexible spring bars 20, oval, elongated openings 27 are milled into a tubular starting part, or the element 19 can also be produced as a die-cast part from an alloy which has sufficient elastic properties, which the small, possible bends ensure the bending spring bars 20.
  • FIG. 4 shows an embodiment variant of the element 19 which has five spiral spring bars 20 'with a round cross section.
  • the element 19 need not be in one piece. Bending spring bars (for example made of glass fiber reinforced plastic) can also be used, which are anchored at both ends in a separate mounting sleeve. Likewise, it is not absolutely necessary to anchor the mounting sleeve 22, which is fastened to the spindle bench 11, on the upper side thereof.
  • Another advantage of the described device is that it can also be used on existing spinning machines without major modifications, because it does not require a special shape either on the spindle bearing housing or on the spindle bench.
  • the device is absolutely aging-resistant in contrast to those bearing attachments in which rubber is used as a suspension or damping element.
