Definitions

  • the present invention relates to a method for producing a layer winding according to the preamble of claim 1 and to a layer winding produced by this method.
  • a method for producing such a layer winding is known from DE-AS 21 57 452. With this method, all insulation layers and also the edge areas for the lateral fixing of the winding conductor are wound from a single, coherent insulating tape. This has the advantage that the winding device for producing the insulating tape layers and the insulating tape edge areas does not have to be stopped; but the disadvantage that the insulating tape edge areas have free spaces that significantly reduce the mechanical strength of the insulating tape edge areas.
  • the object of the present invention is to achieve this known method and the method To improve the layer winding to be delivered so that the insulation has as little or no free space as possible even in the edge of the insulating tape.
  • the present invention practically completely eliminates the free spaces in the edge regions of the winding layers which have been bothersome for mechanical and also for electrical reasons. This gives mechanically very stable edge areas and thus also a high mechanical strength of the entire layer winding. Since the edge regions no longer have any free spaces, the electrical strength is also better than in the case of layer windings, as can be produced using the previously known method. Furthermore, in contrast to the previously known method, edge strips of different widths can also be used and thus edge regions of the windings of different widths can be produced. By using, for example, a harder insulating material for the edge strip, an additional strengthening of the layer winding can be achieved.
  • FIG. 1 denotes a coil former, for example made of plastic, Pertinax, pressboard or the like.
  • an insulating tape 2 for example made of paper or a plastic film, is applied approximately in the middle third of an edge area 3 of the right first edge 4 and wound with a certain initial slope.
  • the slope here is dimensioned such that a triple layer results as the first insulating layer 5 with an overlap width of one third.
  • an insulating edge strip 6 is inserted or applied and / or glued and wound into an edge 4, the height H 1 of which is at least approximately equal to the height of the insulating layer 5 and the height of the winding layer 7, one made from a winding wire 8 winding layer winding 9 is.
  • the insulating tape 2 is wound in the same direction as the winding wire 8.
  • the width of the edge strip 6 is smaller than the width of the insulating tape 2.
  • the cross section of the winding wire 8 can be round, square or rectangular. Foil conductors can also be used.
  • the winding wire 8 itself is insulated in a manner known per se, for example surrounded by lacquer and / or provided with a wound or the like.
  • the winding wire 8 is placed on the inside 10 of the first edge 4.
  • the insulating tape 2 and the winding wire 4 are then wound in the direction of arrow 11 with the insulating tape 2 leading.
  • the remaining tape 15 (see FIG. 3) of the insulating tape 2 is wound with the constant width of approximately 33% to 25% of the original tape width, in particular together with the edge strip 6 '.
  • the edge wedge which is formed in the usual winding with a slope during the winding back and forth and is penetrated by free spaces is avoided and all the free spaces 16 which otherwise arise are filled.
  • the last left third of the tape is no longer wound in the first insulation layer 5, so that this insulation layer 5 there is only 2 layers. Filling in the resulting there in itself free space 16 is obtained so that the next layer of the edge strip 6 1 is wound with the remaining band "15 of constant width. The space 16 located below is thus filled.
  • the length or number of turns with the remaining tape 15, which is then wound further without an incline, is dimensioned such that the surface of the second edge 4 'again runs at least almost parallel to the winding axis. Then the remaining band 15 cut off and glued or pinned with the end p 17 at its last position or possibly on the edge strip 6 '.
  • the insulating tapes 2 or the edge strips 6, 6 ' can each be glued with a one-sided adhesive, in particular self-adhesive, insulating adhesive tape.
  • edge 4 ' is wound up by the edge strip 6' up to the height H 2 of two winding layers, which here corresponds approximately to the height of the first insulating layer 5 and twice the diameter of the winding wire 8. Then the edge strip 6 'is cut off and its end 18 (see FIG. 3) is glued on.
  • edges 4 and 4 ' further edge strips made of a material with a different hardness, density, electrical or mechanical strength, good absorbency with layer windings to be impregnated later or the like can be wrapped.
  • the edge strip 6, 6 ' may also be thicker than the thickness of the insulating tape 2.
  • the first winding layer 7 is still fully wound with the winding wire 8 until the winding wire 8 lies against the inside of the edge 4'.
  • the insulating tape 2 is applied directly in the middle third of the edge 4 'with a predetermined slope and both the insulating tape 2 and the winding wire 8 are now wound in the direction of arrow 19 with the opposite slope and feed direction.
  • the insulating tape 2 overtakes the winding wire 8 due to its larger pitch.
  • the insulating tape 2 arrives first and the edge is built up at the edge 4 with a double turn height H 2, as described using the edge 4 '.
  • winding continues in the direction of the arrows 20, 21, etc. until the calculated coil size of the layer winding is reached.
  • the insulation layer 5, 5 ', 5 ", etc. is made as uniform as possible on a tap 22, for example by connecting the winding wire 8 or applying and connecting a connection or the like the pitch of the insulating tape 2 in the region of the tap 22, in particular on both sides thereof, is increased in accordance with the permissible positional tension.
  • the pitch of the insulating tape 2 is reduced in this area.
  • the slope of the insulating tape 2 is gradually or continuously reduced in a manner known per se as the layer voltage rises.
  • the slope of the insulating tape 2 can also be made smaller in middle winding layers than in winding layers lying further outward, since there are higher electrical levels as a result of greater heating or the like Loads can occur.
  • the cutting edge 23 of the remaining strip 15 or of the entire inclined end section may be provided further inwards than the outer edge 24 of the edge strip 6 or 6 'corresponds to.
  • the direction of rotation of the coil former 1 is represented by an arrow P in FIG.
  • the insulating tape 2 is returned in the opposite direction after the maximum edge overhang has been reached and if the insulating tape 2 or the remaining remaining tape 15 is then wound on without any feed until the edge 4 'is formed up to twice the height H 2 of a winding layer.
  • a particularly good mechanical bond between the insulating tapes 2 and the edge strips 6, 6 ' is obtained if, at the time of or after the beginning of the insulating tape cutting, an edge strip 6' is put on or inserted and fastened on the insulating tape 2. It is also advantageous if the edge strip 6 'is at least partially wound together with the insulating tape 2 or with the remaining tape 15 up to twice the height H 2 of a winding layer.
