Definitions

  • ABSTRACT Electric coils having closely packed turns are wound on a former composed of a tubular body and spacedapart flanges extending out from the body and defining an annular space on which the coil is wound.
  • the body of the former has a substantially flat crossing face that is defined between substantially straight,
  • each turn of each layer of wire in the coil is wound with the wire axis centered on a plane perpendicular to the axis of the body of the former in all portions of the turn except for that portion which overlies the crossing face.
  • the wire is displaced in a direction parallel to the axis of the body a distance equal to a predetermined pitch distance between the wires of the respective layers.
  • the end of the wire that begins the coil overlies the crossing face, and concavities are provided in each face of the flange in the Zones subtended by the angularly related planes that define crossing face, the concavities receiving portions of the wire where the last turn of one layer changes into the first turn of the next layer.
  • the former on which the coil is wound has notches that guide and position the first layer wound on the former.
  • One type of winding machine known heretofore comprises a guide that is moved in a direction parallel to the winding axis in a controlled manner in that the movement parallel to the axis of the coil being wound is a function of the rotation of the former on which the coil is wound, the control being such as to produce a winding having closely packed turns.
  • the first layer of turns is frequently somewhat irregular, principally as a result of the presence of the lead-in end of the wire that forms the beginning of the coil.
  • each turn in each layer of the coil must cross over a turn or turns of the previous layer at least at one point in each turn. Since each turn nests over most of the perimeter of the coil in a space between previous turns, thus producing a total thickness of two layers that is less than twice the diameter of the two wires while, at the same time, each cross over point involves a minimum thickness equal to twice the diameter of the wire, there are points of greater thickness in a portion of each turn of each layer constituted by the crossing points where'a turn of one layer crosses a turn of another layer. In-known machines, the positions of the crossing points are not controlled and occur in a random and erratic manner. Accordingly, the coil tends to develop with an irregularvtotal thickness because of the random location of zones of greater thickness due to the random distribution of cross over points.
  • electric coils having closely packed turns are wound on a former having a tubular body and spaced-apart flanges extending out from the body and defining an annular space between them where the coil is wound.
  • the body of the former has a substantially flat crossing maintaining each turn of the wire in each layer of the coil substantially in a plane perpendicular to the axis of the body of the former in all portions of such turn, except for the portion which overlies the crossing face, and displacing each turn in each layer a predetermined pitch distance in a direction parallel to the axis of the body substantially exclusively in said portion thereof which overlies the crossing face.
  • the axes of the major portions of each turn of each layer lie in planes substantially perpendicular to the axis of the coil, and all portions of each turn of each layer which cross corresponding portions of underlying layers overlie the crossing face.
  • the former on which the coil is wound is provided with guiding and positioning notches at least along each edge adjacent each line defining the crossing' face.
  • the notches are uniformly spaced apart a distance equal to the pitch distance between the turns of each layer of the coil.
  • the distance between each turn is not less than and not substantially greater than a distance equal to the diameter of the wire and preferably is between 1.00 and 1.04 times the diameter of the wire.
  • Such a pitch distance provides mutual contact between the sides of the wires (or a very small spacing between the wires).
  • Corresponding notches at each edge of the crossing space lie in a common plane that is perpendicular to the axis of the former, thereby insuring that the portions of the turns in areas that do not overlie the crossing face of the former are centered on planes perpendicular to the axis of the former.
  • the notches may extend continuously on planes perpendicular to the axis of the former between the edges of the crossing face.
  • the end notches immediately adjacent one flange of the former are centered on a plane that is spaced a distance from the flange that is equal to one-half the pitch distance of the series of notches, while the end notches adjacent the other flange of the former are spaced a distance from the other flange equal to the pitch distance between the notches.
  • Each flange of the former is preferably provided with a concavity in its inner face, the concavity lying within a zone defined between lines of intersection between the face of the flange and the aforementioned radialaxial planes that define the crossing face.
  • the concavities allow the portions of the wire where the last turn of one layer merges into the first turn of the next layer to make a smooth transition from one layer to the next, each transition portion being partially received within the concavity.
  • the starting end of the wire where the coil begins is preferably received in the concavity and overlies the crossing portion of the tubular body of the former.
  • FIG. 1 is a pictorial view of an end portion of one embodiment of a former used for winding the coil;
  • FIG. 2 is a pictorial view of the former shown in FIG. 1, the view being on a smaller scale than in FIG. 1 and the former being shown in a different orientation from that of FIG. 1;
  • FIG. 3 is a side view in cross-section of the former shown in FIGS. 1 and 2;

  • FIG. 7 is a half longitudinal cross-sectional view of a former having layers of a coil wound on it, a portion of the view being broken out to reduce the size of the view, and the view being taken at a zone of the coil outside of the crossing face;
  • FIG. 8 is a cross-sectional view, also with a center portion broken out, taken just outside the beginning portion of a second layer of wire wound on the former and viewing the zone overlying the crossing face of the former;

  • the coil is woundon a coil former that is composed of a tubular body 1 having, in transverse cross-section, a rectangular shape (see FIG. 4) and two flanges 2 and 3 which are substantially rectangular and are positioned at the ends of the tubular body.
  • the crosssectional shape of the tubular body and the shapes of the flanges may, of course, be varied in accordance with the desired cross-sectional shape of the coil. In the embodiment, itshould be evident that the resulting coil wound on the former will be substantially rectangular in cross-section.
  • the lines designated by the letters XX in FIG. 1 represent the axis of the tubular body 1 of the former. Radial-axial planes, that is planes that extend radially and include the axis X ofthe former, intersect the surface of the tubular body along lines that define on the surface of the body a substantially flat crossing face 4, bhe two imaginary radial-axial planes intersecting at an angle.
  • the lines of intersections just referred to constitute the edges where the flat faces of the rectangular tubular body intersect.
  • a flat crossing facedefined by straight lines of intersection between radial-axial, angularly' related planes is an important feature of the inven- The embodiment of the former illustrated in F IGS. 1
  • notches 5 located at each edge where the facesof the tubular body intersect.
  • such notches will be provided at least along both edges of the crossing face of the former and often will extend continuously between the edges in the portion of the tubular body of the former outside of the crossing face.
  • Corresponding notches at either edge of the crossing face are located in common planes perpendicular to the axis XX of the former.
  • the notches in the embodiment of FIGS. 1 9 are V-shaped with the pitch dis tance P measured in a direction parallel to the axis of the former between the centers 6 of the notches being equal to the pitch distance between the turns of the wire. As illustrated in FIG.
  • the center lines 6a of the first notches adjacent one of the flanges 2 of theformer are spaced a distance from that flange (flange 2) equal to one-half of the pitch distance between the notches, that is, adistance P/2, where P designates the pitch distance.
  • the center line 6b of the end notch along each edge of the crossing face 4 adjacent the other flange 3 of the former is equal to the pitch distanceP.
  • each of the flanges 2 and 3 of the former is providedwith a concavity 7 and 8, the respective concavities in the flanges being defined generally by the intersections between the internal faces of the flanges and the imaginary angularly related, radial-axial planes that also define the crossing face 4 (see FIG. 4

  • the depth at the base of tion parallel to the axis XX of the body in the direc- 9 of the drawings has a multiplicity of uniformly I each form of concavity, measured at a direction paral- Iel to the axis XX of the body 1 of the former, should be between about P/3 and P/l.5.
  • the internal face of each flange in the area outside of the'concavity should be flat and lie in a plane perpendicular to the axis XX.
  • the method of forming a coil onthe former involves rotating the former about its axis XX and guiding the wire being wound so as to maintain the portion of the wire being pulled onto the coil in a substantially fixed position when the wire is being applied against that portion of the coil overlying the surface of the former outside of the crossing face and-moving the wire in a direction of the next turn of the wire over a distance equal to the pitch P between the notches during the time that the wire is being applied against the crossing face 4. More particularly, referring to FIG. 8 of the drawings, the coil is started by leading the end 10 of a wire out through a hole 9 in the flange 2 of the former, which flange isadjacent to the notch 5a that is centered onehalf pitch distance from the flange.
  • the hole 9' is located generally at the center of the concavity 7 in the flange 2, which is also a central location adjacent the crossing face 4.
  • the former is then rotated to draw the starting portion of the first turn 11 of the wire into the first notch 5a of the former.
  • the portion 1 1a of the wire which overlies the crossing face 4 resides in the concavity 7 and lies flat against the crossing face 4.
  • the wire guide is-then held stationary as the former rotates about its axis so that the first turn of the wire around the portion of the body of the former outside of the crossing face 4 has its axis aligned on a plane perpendicular to the axis XX of the former. Accordingly, the wire reaches the first notch 5a on the other edge of the crossing face 4.
  • the wire lying that part of the body outside of the crossing face is guided in a direction parallel to the axis XX a distance equal to the pitch distance P so that the wire is received in the next notch 5 at the opposite edge of the crossing face.
  • Each additional turn of the'first layer progresses in the manner described above, namely, by holding the wire guide stationary as it is laid on the former body in the zone outside of the crossing face and then guiding the wire in a direction parallel to-the axis XX of the former a distance equal to the'pitch distance P during the time that the wire is laid on the crossing face 4.
  • the first layer comprises turns of wire, each of which includes a'portion outside of the crossing face where the axis of the wire lies in a plane perpendicular to the axis XX of the former and a portion overlying the crossing face 4 in which the wire is located at an angle to a perpendicular plane and is shifted one pitch distance P parallel to the axis XX of the former from one edge to the other edge of the crossing face 4 in the direction of the progression of the turns on the layer.
  • transition turn 14 begins at the end of aportion of the preceding turn in which the axis of the turn in the region outside of the crossing face lies in the plane perpendicular to the axis XX of the former, the end of such portion residing in the last notch 5b at the edge of the crossing face.
  • the wire is drawn onto the crossing face 4 it is guided in a direction toward theflange 3 parallel to the axis XX a distance equal to one-half P.
  • a portion 14c of the turn 14 lies against the crossing face 4 and is received in the concavity 8 on the interface of the flange 3, butas the wire progresses across the face 4 it begins to ride up on the preceding turn of the layer, since the space between the preceding turn and the face of the flange is no longer adequate to accommodate all of the wire.
  • the turns of each layer in portions of the circumference of the coil lying outside the zone bounded generally by the radial-axial planes defining the edges of the crossing face are staggered so that the turns of a given layer are centered between the turns of the layers below and above the given layer (see FIG. 7).
  • the portion of each turn of each layer overlying the crossing face 4 crosses over two turns of the layer underlying it and crosses under two turns of a layer overlying it. As illustrated in FIG. 9, therefore, the turns of the respective layers in the coil overlying the crossing face 4 are stacked one above the other.
  • the thickness of the coil in the zone lying outside of the zone overlying the crossing face is somewhat less than the-sum of the diameters of the number of layers of the coil, while the thickness of'the coil in the zone overlying the-crossing face is generally equal to the in which the wire overlies the crossing face 4 a portion 14b of the transition turn is nested between the flange 3 and the preceding turn of the wire. From the portion 14b around to the portion 14d of the transition turn, the axis of the wire lies substantially in a plane perpendicular to the axis XX of the former with one edge of such portion supported against the flange 3 and another portion of the wire nesting against the preceding turn.
  • the next turn 15 of the wire begins by shifting the wire parallel to the axis XX during the time that the wire is pulled across the face 4, a distance equal to one pitch distance P, the direction being opposite from the lay of the first layer, as is evident from FIG. 8. From this point on, the winding procedure progresses as in the first layer in that each turn includes a portion overnumber of turns multiplied by the diameter of the wire.

  • the invention provides the production of a coil having a maximum packing of the turns without any chance for disorder or disruption in the arrangement of the turns.
