Definitions

  • the present invention rel-ates to a device for imparting a fast rotation movement to a body of revolution, and in particular to a false twist spindle in a crimping machine for textile yarn.
  • the body of revolution to be driven is supported by two parallel driving circular members adjacent to each other and it is driven by at least one of said members against which it is applied by the magnetic field produced by a permanent magnet.
  • the invention is characterized in that the permanent magnet is in the form of a body of revolution coaxial with at least one of said members and rotating together therewith.
  • FIG. 1 shows, partly in axial section and partly in elevational view, a driving device for a false twist spindle in a textile yarn crimping machine, said driving device being made according to the present invention
  • FIG. 2 is a cross section of the device of FIG. 1;
  • FIG. 3 is a view similar to FIG. 4 showing another embodiment of the invention.
  • FIG. 4 is a view similar to FIGS. 1 and 3 and illustrating still another embodiment of the invention.
  • FIG. 5 is a view analogous to FIG. 2 showing a modification
  • FIG. 6 is a view analogous to FIGS. 2 and 5 and relating to a simplified device according to the invention for driving a plurality of spindles;
  • FIG. 7 is an axial sectional view of a tubular false twist spindle made according to the invention.
  • FIG. 8 is a cross section corresponding to FIG. 7.
  • One of the discs may turn freely about its axis and serve merely as support for the spindle, whereas the other transmits the rotation movement.
  • the permanent magnet is in the form of a body of revolution coaxial with the driving disc and rotating together with it.
  • spindle 1 is supportedby two bearings 10 and 11 consisting of two large diameter discs 10 and 11 (corresponding to the above mentioned discs 2 and 3) mounted on respective shafts 6.
  • One of said shafts is driven through a belt 4.
  • magnet 5 consists of a tube mounted between two rings 7 and 8 of ferro-magnetic material forming pole pieces at the respective ends of said tubular magnet 5. These rings 7 and 8, chamfered at their peripheries, are located respectively opposite collars 12 and 13 of spindle 1 so that the magnetic flux of magnet 5 closes through said collars 12 and 13 and spindle 1.
  • said spindle 1 is magnetically drawn against annular flanges 10 and 11 carried by a sleeve 9 tightly held between each shaft 6 and the corresponding tubular magnet 5.
  • -Sleeve 9 and flanges 10 and 11 are made of a non-magnetic material such as aluminum, bronze, or a suitable alloy of plastic material.
  • rings 7,, and 8 are of a diameter greater than that of flanges 10,, and 11 and serve directly to support spindle 1
  • said spindle 1 is provided with collars 12,, and 13 located at a distance from each other greater than the distance between rings 7,, and 8,, on which the spindle is beating.
  • each of the bearings of spindle 1 consistsof a .part 15 of non magnetic material surrounding the corresponding magnet 5 between'rin'gs 7 and 8 this part 15 having a diameter greater than that of said rings.
  • spindle 1 On either side of part 15, spindle 1 is provided with a collar 12,,, 13 The axial distance between these collars is greater than the width of part 15 and corresponds to the distance between rings 7 and 8;, so that, when spindle 1 rotates on its single rolling path 15, collars 12 and 13,, are located opposite rings 7,, and 8 respectively, under the efiect of'the magnetic field which, from these rings, closes through spindle 1 and collars 12 and 13,,.
  • Part 15 may consist of a sleeve of plastic material force fitted on a ring 16 of a non magnetic metal bearing upon shoulders provided in rings 7 and 8 Ring 16 is held, together with magnet 5, between rings 7,, and 8 through flanges 10 and 11 flange 10,, being integral with sleeve 9,, on which flange 11 is slidable. Said flange 11 is pushed toward the left *by two nuts 17 screwed on sleeve 9 In some cases, it may be advantageous to provide, at the periphery of the rings such as 7 and 8 and of the collars such as 12 and 13 (or in the embodiment of FIG.
  • a yarn crimping machine has, over machines of the same kind including in the magnetic circuit thereof a fixed member for keeping the spindles applied against their driving discs, many advantages and in particular the following ones:
  • the heating of the spindle is greatly reduced, which permits of reducing the wear and tear of spindles of this type and to improve the quality of the yarn that is obtained;
  • Thedrive is much more efficient, especially when every disc is provided with its own magnet and the risks of slipping are greatly reduced.
  • a device for driving at high speed a spindle of a term-magnetic material which comprises, in combination, two parallel circular members having their respective axes parallel to the axis of revolution of said spindle and forming bearings for said spindle, means including one of said members, for driving said spindle in rotation about its axis, at least one tubularpermanent magnet coaxial with one of said members and fixed with respect thereto, and two rings of a ferromagnetic material fixed at the respective ends of said tubular magnet coaxially therewith, said rings having. an outer diameter greater than that of said tubular magnet and constituting magnetic pole pieces for it, said rings extending toward said spindle to close, together therewith, a magnetic circuit for urging said'spindle against said circular members.
  • a device for driving at high speed a spindle of a ferro-magnetic material which comprises, in combination, two parallel circular members having their respective axes parallel to the axis of revolution of said spindle, at least one tubular permanent magnet coaxial with one of said members and fixed with respect thereto, two rings of aferro-magnetic material fixed at the respective ends of said tubular magnet coaxially therewith, said rings having an outer diameter greater than that of said tubular magnet and constituting magnetic pole pieces for it, said rings extending into contact with said spindle to close, together therewith, a magnetic circuit for urging said spindle against said circular members, the rings of both of said members forming bearings for said spindle, and means, including one of said rings, for driving said spindle about its axis.
  • a device for driving at high speed a spindle of a term-magnetic material which comprises, in combination, two parallel circular members of non magnetic material having their respective axes parallel to the axis of revolution of said spindle, each of said members including a pair of flanges forming bearings for said spindle, means,'including one of said members, for driving said spindle in rotation about its axis, at least one tubular permanent magnet coaxial with one of said members and fixed with respect thereto, two rings of a term-magnetic material fixed at the respective ends of said tubular magnet coaxially therewith, said rings being located between the flanges of said two pairs, said rings having an outer diameter.
  • a device for driving at high speed a spindle of a. 'ferro-magnetic material which comprises, in com-bination, two collars carried by said spindle coaxially therewith at an axial distance from each other, two parallel annular members having their respective axes parallel to the axis of revolution of said spindle and forming bearings for said spindle between said collars, means, including one of said members, for driving said spindle in rotation about its axis, at least one tubular permanent magnet coaxially located inside one of said members and fixed with respect thereto, two rings of a ferro-magnetic material fixed at the respective ends of said tubular magnet coaxially therewith, said rings having an outer diameter greater than that of said tubular magnet and constituting magnetic pole pieces for it, said rings extending toward said spindle opposite said collars, respectively, to close together therewith, a magnetic circuit extending through said spindle for urging it against said annular members.
  • a device wherein the cooperating ferro-magnetic portions located respectively on said spindle and on said magnet have magnetic'reluctance areas varying cyclically along their periphery.
  • a device wherein said spindle is provided with a slot at one of its ends, further corn-' prising a substantially dia metral cross member provided with a V-shaped notch, the bottom of the V extending substantially along the axis of rotation of said spindle.
