Definitions

  • the invention relates to a spindle with a single electric motor drive for a spinning machine, which can be attached to a spindle bench and which has a shaft mounted in a bearing housing, which is connected in a rotationally fixed manner to a rotor, the associated stator of which is connected in a rotationally fixed manner to the bearing housing held on the spindle bench is.
  • the invention relates to a state of the art, as it results for example from EP application 0 304 869.
  • the invention has for its object to provide a spindle with a single electric motor drive with reduced resonances and natural vibrations.
  • the spindle shaft is mounted essentially only between the rotor and the upper free end of the spindle shaft and the bearing housing is held on the spindle bench by means of damping elements.
  • the bearing which is preferably designed as a combined radial and axial bearing, is preferably arranged in a recess in the spindle bank, the stator and its housing are placed from below over the rotor (connected to the lower spindle end in a rotationally fixed manner) and screwed to a flange or collar on the bearing housing. It is essential in both variants to interpose rubber-elastic damping elements between the fixed bearing part and the bearing housing.
  • the bearing 1 essentially comprises a shaft 1, which is mounted in its central section in a combined axial / radial bearing 2.
  • the bearing 2 is surrounded by a two-part bearing housing (inner 16 and outer bearing receiving sleeve 17) which has flanges 4 and 5 at both ends.
  • the bearing housing is fastened to a spindle bench 7 by means of screws 6.
  • an asynchronous rotor 8 is rotatably attached, which is constructed in the usual way, i.e. has a laminated core with a cage formed from rods and short-circuit rings, which is supported as a whole by an anchor sleeve 9 which is pressed onto the lower end of the spindle 1.
  • an asynchronous motor instead of an asynchronous motor, another type of motor can of course also be used.
  • the associated stator 10 has a laminated core 11 and a winding 12 which is inserted into the slots in the laminated core 11.
  • the stator 10 is inserted, preferably pressed, into a pot-shaped stator housing 13.
  • the stator housing 13 and thus the stator 10 are fastened to the lower flange 5 of the bearing housing 3 by means of screws 14.
  • the clear width of the bore 15 in the spindle bank 7 is dimensioned only a little larger than the maximum outer diameter of the stator housing 13. This allows the spindle 1, including all of its components, to be mounted from above.
  • the bearing housing 3 is essentially formed in two parts and consists of an inner bearing receiving sleeve 16, which is integrally connected at the lower end to the lower flange 5, and an outer bearing receiving sleeve 17 radially spaced from the bearing receiving sleeve. which carries the upper flange 4 at the upper end.
  • the outer bearing receiving sleeve 17 is provided at both ends with recesses 18, 19, one wall of which is axially parallel, while the other wall is inclined approximately 60 ° with respect to the spindle axis.
  • O-rings 20, 21 made of rubber-elastic material are inserted.
  • the mutual bracing of the outer 17 and inner bearing receiving sleeve 16 takes place by means of a pressure ring 22, which is either screwed onto the inner bearing receiving sleeve or, as in the example by a locking ring 23, which engages in an annular groove 24 on the inner bearing receiving sleeve 16.
  • stator 10 together with the housing 13 are decoupled from the spindle bench 7.
  • the O-rings 20, 21 also perform a spacing function.
  • the attachment of the stator 10 to the inner bearing receiving sleeve 16 has the additional advantage that inaccuracies in the spindle assembly do not influence the centering between the rotor 8 and the stator 10. There is also no streaking of the rotor 8 on the stator when the spindle drive is started up.
  • outer bearing shell which is designed as an elongated cylinder 25, simultaneously forms the inner bearing receiving sleeve (item 16 in FIG. 1). This is provided at the lower end with a flange 5 'to which the stator housing 13 and thus the stator 10 is screwed.
  • a tube piece 26 is fastened to the spindle bench 7 and fulfills the function of the bearing receiving sleeve 17 according to FIG. 1 or 2. Accordingly, it has indentations 18, 19 at both ends, the geometry of which was described in connection with FIG. 1.
  • FIG. 3 is functionally equivalent to the versions according to FIGS. 1 and 2; only the assembly is different:
  • the spindle 1 including the flanged stator housing 13 is inserted from below into the bore of the pipe section 26, the upper O-ring is pulled in.
  • the O-rings 20 and 21 are clamped evenly by means of the pressure ring 22.
  • this variant can also be used with a spindle according to FIG. 1. 4, in contrast to the previously described embodiments, essentially only the rotating part (essentially spindle 1 and rotor 8) is elastically supported and decoupled from the spindle bench 7.
  • These rubber rings are in turn vulcanized into the inner bore 30 of a double flange tube 31 with flanges 4 ⁇ and 5 ⁇ .
  • the double flange tube 31 ends at the upper end in a cylindrical extension 32 which is adapted to the bore 15 in the spindle bank 7.
  • stator 10 together with the housing 13 is attached to the lower flange 5 ⁇ by means of screws 14, the double flange tube itself to the upper flange 4 ⁇ by means of screws 6 on the spindle bench 7.
  • a locking ring 33 which engages in a groove 34 in the inner wall of the double flange tube and interacts with the projection 27a of the sleeve 27, secures the mutual axial position of bearing 2 (and thus spindle 1 and rotor 8) and double flange tube 31.
  • the double flange tube 31 can also be firmly connected to the spindle bench 7.
  • the upper flange 4 ⁇ is then omitted.
  • they are not vulcanized directly onto the inner bore 30 of the double flange tube 31, but rather onto the inner wall of a bushing.
