Definitions

  • the invention relates to a spinning or twisting machine according to the type mentioned in the preamble of claim 1.
  • Such machines are used for spinning or twisting yarns. It is known to drive each textile spindle of such a machine by means of a separate electric motor which is only assigned to it. Such a drive is also referred to as a single drive for the spindles.
  • a drive is also referred to as a single drive for the spindles.
  • This ring which is also known as a spinning or twisting ring, serves to carry a ring traveler, which is dragged all around on this ring by the yarn running towards the spindle.
  • the spindle shaft is very well centered in all positions of the ring bank performing the lifting movements during operation in relation to the ring which is correspondingly moved up and down with the ring bank, because otherwise the risk of thread breakage is increased and runner wear is increased or even reduced Impact of the ring traveler can occur on the yarn winding body, which is on a sleeve attached to the / spindle shaft in the winding.
  • both end shields of the housing of the electric motor on the spindle bench are arranged radially adjustable on all sides independently of one another, the spindle shaft can be quickly and precisely centered in a structurally simple manner in relation to the ring penetrated by it via the maximum lifting height of the ring bench carrying this ring.
  • the textile spindles are normally arranged in two rows, namely one row on each longitudinal side of the machine.
  • those bearing a ring row, penetrated by the spindle shafts and bearing ring travelers Rings are expediently arranged on a single ring bank, but here too, if necessary, several ring banks can be provided per row of spindles.
  • the rotor shaft of the electric motor of the textile spindle can be made in one piece with the spindle shaft or with a central longitudinal mandrel of the spindle shaft or the spindle shaft and / or a central longitudinal mandrel of the spindle shaft can be designed as a separate part and fixedly connected to the rotor shaft of the rotor of the electric motor.
  • the radial positional adjustability of the relevant end shield of the electric motor of the spindle is understood to mean that the end shield can be adjusted radially in all directions with respect to the axis of rotation of the textile spindle.
  • the radial position adjustment option of the individual end shield generally only needs to be relatively small, for example at least in many cases 2 to 8 mm radial position adjustability or in some cases even less or more are sufficient, depending on the manufacturing tolerances.
  • both bearing plates or one of the two bearing plates can be fixed immovably on the spindle bench.
  • the relevant end shield or a ring washer attached to it have threaded holes into which holes of the spindle bank with considerable lateral play penetrating threaded shafts of fastening screws can be screwed, which hold the end shield immovably on the spindle bank in the once set position and whose heads are supported on the spindle bank via washers are.
  • the rotational axis of the textile spindle must be able to be pivoted transversely to its longitudinal direction to a limited extent by radial position adjustment of at least one of the end shields, it is necessary to provide that this pivoting movement is possible. To do this, it is sufficient if one of the two end shields with the spindle bank is resilient via at least one such pivoting movement permitting elastic member, for example.
  • the other end shield is also to be immovably connected to the spindle bench, it can be provided, for example, to connect it to the spindle bench via a lockable ball joint, for example to attach a pan to the spindle bench so as to be radially adjustable, which is designed as a ring section of a circle, has bearing surface coaxial with the axis of rotation of the textile spindle, against which a complementary bearing surface of the bearing plate rests and that the ball joint can be locked, for example by tensioning the socket with the bearing plate, ie its two bearing surfaces can no longer slide on one another.
  • a lockable ball joint for example to attach a pan to the spindle bench so as to be radially adjustable, which is designed as a ring section of a circle, has bearing surface coaxial with the axis of rotation of the textile spindle, against which a complementary bearing surface of the bearing plate rests and that the ball joint can be locked, for example by tensioning the socket with the bearing plate, ie its two bearing surfaces can no
  • both end shields are connected to the spindle bank by at least one elastic member each.
  • the electric motor can be of any suitable type, for example an asynchronous motor with a squirrel-cage rotor or a self-starting synchronous motor, for example a shaded-pole motor.
  • the rotor of the electric motor can preferably be mounted in both bearing plates by means of plain bearings and by means of a track bearing located in the lower bearing plate.
  • the spindle bench 10 and the ring bench 12 extend essentially over the length of the machine in question.
  • the spindle bench 10 can be fixedly arranged on the machine frame and the ring bench 12 is guided vertically straight and can be driven to steady lifting movements by means of a lifting mechanism, not shown.
  • the lowest possible position of the ring rail 12 is shown in full lines and the highest possible position of the ring rail 12 is shown in dash-dot lines.
  • a larger number of rings 13, also known as spinning or twisting rings are arranged in a row as usual.
  • a ring traveler (not shown) can be placed on the ring 13, through which the yarn running towards the textile spindle 11 and to be wound onto the sleeve (not shown) to be plugged onto its spindle shaft 14 runs and thereby drags this ring traveler on the ring 13 /.
  • the spindle bench 10 consists of a rigid tube of square cross section.
  • This spindle bench 10 has a circular hole 16, 17 on the top and bottom for each textile spindle 11 to be arranged on it.
  • the diameter of the upper hole 16 is slightly larger than the outer diameter of the electric motor 19 of the textile spindle 11 to be inserted through it downward into the interior of the spindle bank 10.
  • This electric motor 19 has a housing consisting of an upper end shield 20, an underside end shield 21 and a cylindrical middle part 22, at the two ends of which end shields 20, 21 are fastened by means of screws such as 24.
  • the middle part 22 of the housing can be a sleeve which surrounds the stator of this electric motor 19 in a known manner or can also be formed by the laminated core of the stator of this electric motor 19, as is also known.
  • the bearing plates 20, 21 contain slide bearings or roller bearings for mounting the rotor shaft 24, which can only be seen in FIG.
  • the vertical spindle shaft 14 of this textile spindle 10 is arranged coaxially with it.
  • This spindle shaft 14 can be made of aluminum, for example, and can be pressed onto the rotor shaft 24.
  • the rotor shaft 24 thus simultaneously forms a mandrel projecting into the spindle shaft.
  • the lower end shield 21 has a cylindrical, downwardly projecting threaded pin 25 fixed to it, the longitudinal axis of which is aligned with the axis of rotation of the electric motor 19 and thus with the axis of rotation of the textile spindle 11 and on which two retaining rings 26, 27 formed as flange rings are made of reinforced or unarmoured elastomeric material, for example made of rubber or elastic plastic, are arranged one above the other.
  • These two retaining rings 26, 27 are of identical design and arranged in mirror image to one another and arranged in a rotationally symmetrical and coaxial manner with respect to the longitudinal axis of the threaded pin 25 on the latter.
  • the upper retaining ring 27 lies with its outer flange on the upper side of the horizontal, flat bottom part 29 of the spindle bench 10 and the lower retaining ring 26 rests on the flat underside of this bottom part 29 of the spindle bench 10. Furthermore, the upper retaining ring 27 rests on a flat end face of the lower bearing plate 21 and the lower retaining ring 26 rests on a washer 30 which is placed on a clamping nut 31 screwed onto the thread of the threaded pin 25, so that the clamping nut 31 is turned by turning the clamping nut 31 the two retaining rings 26, 27 between the end shield 21 or washer 30 and the base 29 of the spindle bench 10 are clamped as shown with a preload that can be adjusted by turning the clamping nut 31 and thus hold this threaded pin 25 and thus the electric motor 19 elastically.
  • the hole 17 has a diameter which is considerably larger, for example 2 to 8 mm larger than that of the short, cylindrical regions of the retaining rings 26, 27 located in it.
  • the upper end shield 20 has a projection 33 in Form of a cylindrical sleeve-shaped extension, which is an integral part of the bearing plate 20 and circumferentially circular cylindrical and coaxial to the axis of rotation of the textile spindle 11.
  • the shape seen in plan view is fixed by gluing or in some other way.
  • This outer ring 35 is placed on the flat, horizontal ceiling 36 of the spindle bench 10 and has at its most distant ends 52 each a circular 37 of a diameter which is so much larger, for example 2 to 8 mm larger than that Outside diameter of this hole 37 penetrating and screwed into a threaded hole in the ceiling 36 of the spindle bench 10 fastening screw 39, the head of which rests on a washer 40, that when the two fastening screws 39 of this outer ring 3-5 are loosened, one man and thus the one with it can move radially on all sides via the elastomeric retaining ring 34 connected to the upper end plate 20 to the extent determined by the oversize of the holes 37 relative to the diameter of the threaded shafts of the fastening screws 39. By tightening these two fastening screws 39, the outer ring 35 can then be immovably connected to the spindle bench 10 again in the set position.
  • rings 13 on the ring bench 12 are radially adjustable, they can initially be left in any radial position and, after loosening the fastening screws 39 and the clamping nuts 31, align all the spindle shafts 14 so that their longitudinal axes are in a common vertical plane and have constant distances from each other.
  • rings 13 are first arranged on the ring bench 12 in such a way that their longitudinal axes have constant distances from one another and lie in a common vertical plane, provided the rings 13 are radially adjustable. If the latter is not the The case is, of course, there is no need to adjust the rings 13, since they are then already in the aforementioned mutual alignment.
  • the ring bench 12 After tightening the screws 37, the ring bench 12 is moved into the highest position and now, as already described above, the spindle shafts 14 are successively centered on the rings 13 located in these new highest positions by radially adjusting the end shields 21 and this centered position then becomes each fixed by tightening the relevant clamping nut 31.
  • each spindle shaft 14 is centered on the ring penetrated by it so that the centering over the maximum lifting height of the ring 13 is very precise throughout, because the centering of the spindle shaft 14 is in the lowest position of the ring 13 when centering the Spindle shaft 14 in the uppermost position of the ring 13 because of the small distance between the lowest position of the ring 13 and the upper one End shield 20 can not change or at most only insignificantly. If, however, the centering on one or the other textile spindle in the lowest position of the spindle bench after centering in the uppermost position of the spindle bench is no longer sufficiently precise, the centering of the spindle shaft 14 can be repeated again, which then because of the more precise starting position even more precisely becomes.
  • the centering of the spindle shaft 14 in the ring 13 can take place or be facilitated by means of teachings known per se or also by optical measurement or in another suitable manner.
  • the rotating part of the textile spindle 10 should be able to behave expediently like a gyroscope during operation, which is readily possible here due to the elastic retaining rings 26, 27 and 34, it can often be expedient to determine the gyroscopic movements of this rotatable spindle shaft 14 and Runner of the electric amplifier motor 19 existing spindle part / dampen.
  • An advantageous damping option is shown in an exemplary embodiment in FIG. 3, which shows only a small part of its lower end plate 21 cut from the electric motor of the textile spindle.
  • This electric motor, as well as the holder of its upper end plate, and the spindle shaft can be designed as in FIGS. 1 and 2. The only deviation to the embodiment of FIGS.
  • This lower bearing plate 21 has an indentation on the underside with a circumferential groove-shaped undercut which is arranged coaxially with a cylindrical pin 45 which is fixedly arranged on the bearing plate 21 and projects downwards and is coaxial with the axis of rotation of the textile spindle, and in which a retaining ring 46 of elastomeric material with a circular cross-section is arranged , for example made of rubber or plastic, which retaining ring 46 is seated in an annular groove of the top outer flange 47 of a pot 49 which is coaxial with the longitudinal axis of the pin 45.
  • This pot 49 is only open on the top and the pin 45.
  • the pot 49 With its lower cylindrical region, the pot 49 penetrates a cylindrical hole 17 in the base part 29 of the spindle bench 10 with considerable radial play of, for example, 2 to 8 mm.
  • This cylindrical pot area has an external thread onto which a nut 31 is screwed, by means of which the pot 49, with its outer flange 47 on the top part on the bottom part 29 of the spindle bench 10, can be securely fastened to the spindle bench 10 in any radially adjustable position.
  • damping spiral spring 50 other damping elements interacting with the damping oil can optionally be arranged in the pot 49, for example, open-pore elastic foam, a sleeve or a plurality of sleeves or cups nested in one another with little play or the like.
