Definitions

  • My invention relates to an electric individual drive for the spindles of spinning machines, artificial silk centrifugals, spinn n pots and other bodies revolving at big to mechanical damage.
  • My invention relatestoan electric individu'al' spindle drive with vertical shaft
  • the invention consists in locating the electric motor, the upwardly extending shaft of which serves as spindle, underneath the spindle rail .and drawing the cooling air through ducts and the wall of the bearing and ejecting it into the atmosphere by means of' a screen disc mounted on the spindle shaft.
  • the fiy-wheel efiect of the bobbin placed upon the spindle and the motor as'a rule very small. any small eccentric irregularity of the bobbin or spool becomes noticeable by the unsteady run 0 the spindle.
  • the-spinning s'pin-' dle is rendered indifferent against such disturbing unbalances by an additional disc flywheel.
  • Fig. 1 of the drawin 1 is which in the operativeposition abut the driving motor vertically mounte 'm an opemng of the spindle rail 3 by means of a flange 2.
  • the shaft 4 of the motor is extended upward and designed as-sp'indle, being, for instance, provided with a tube 5 for spooling a' thread er'filament.
  • the spindle is journaled in the bearing 7. Since f the bearing 7 form closed channels or ducts 8. Above the bearing 7 is located the screen disc 9 which owing to the high speed of rotation has a strongly exhausting ,action and thus draws the air through the channels in the motor casing and the ducts in the bearmg so that the motor and the bearing are efliciently cooled.
  • the disc 9 consists preferably of sheet steel and need not be provided with fan a high speed that even. the smooth surface entrains the air and a sufiicient circulation of .the air is set up in this way.
  • the screen disc has a comparatively considerable blades as it revolves at such spin spindle is pushed into" the openin in the thickness, so that it acts like a flywheeland thus. com nsates any unbalanced condition of the spindle which may exist. To reduce mechanicalmaterial stresses the mass of the disc is reduced in thickness at the circumferenc'e.
  • Fi' 3 of the drawings shows a spinning (fie secured in easily exchangeable man nor in the spindle rail 13, and maintained in working position by springs 18.
  • These s rings 18 are attached to the flan es-12 xed upon'the casing of motor 11 an e a recessed portion 16 in the spindle rail 13 when the spindle occupies its working position.
  • the supply of current to the motor lace by means of the busbars 21 takes locate underneath the spindle rail '13.
  • Against these bus bars 21 are placed the elastic contacts 22 connected to the terminals of the motor 11, so that the motor is at once connected to the busbars when the spindle rail.
  • Upon the casing of t e motor 11 isalso mounted the push-button switch 23.
  • the spindle 14 carrying the bobbin 15 is provided with a disc 19 acting as flywheel.
  • the rotor of the driving motor 11 is not as in Fig. 1 freely'suspended, but is supported at the bottom in the lower bearing 20 of p the motor casing besides being journalled- .ing 20, the motor 11,' as well in' the spindle bearing 17 at the top.
  • the cooling ribs upon th casin ofthe motor 11 are surrounded by a she or jacket 2i, so that closed channels or ducts are formed through which the cooling air sucked in by the dlsc'flywheel 19 sweeps and thus effectively cools the lower motor bearas the upper spindle bearing 17.
  • a The elastic attachment of the spindle in the spindle rail enables the axis of the spindle to set itself in the correct position, which is of vital importance for the steady run of the spindle at the high velocities attained.
  • e arrangement illustrated in Fig. .3 has the further advantage that theentire electric attended current carrying parts is efl'ectively avoided.
  • a bearing located betweensaid motor andsaid spindle and having air coolupon the end of the bearing 17 and engag emay be easil from the spirit and.
  • a spindle rail an electric motor having an upwardly extending vertical shaft end serving as sp1nning spindle, a bearinglocated between said motor and said spindle having air cooling ducts provided at its outside, a shell enclosing said ducts and having a flange for attaching the entire drive to said spindle rail, and a screening disc mounted upon said shaft between the spindle and said bearing, said disc being designed as flywheel and adapted to draw air through the cooling ducts'of said bearing.
  • a spindle rail In an electric high speed individual spindle drive,-in combination, a spindle rail, an'electric'motor having an upwardly'extended vertical shaft end serving as spinning spindle, a bearing located between said motor andsaid spindle and having air cooling ducts provided at its outside, a shell enclosing said ducts andhaving two flanges, said spindle rail having an opening for receivin gthe drive between said two flanges, "springs mounted upon said flanges adapted to maintain thedriving device elasticallyvin posi tion, and a screen .disc mounted on the said draw air through the cooling ducts.
