Definitions

  • the invention is based on a magnetic holder or
  • the retaining element is not in one piece with the carrier ring and must be screwed onto the carrier ring by means of two screws for one magnet each.
  • the magnet holder according to the invention and the methods according to the invention for fastening a magnet on a carrier element with the characteristics and features of claim 1 or claims 12, 13 have the advantage over the above that magnets can be fastened on a carrier element in a simple manner.
  • the measures listed in the dependent claims allow advantageous developments and improvements of the device mentioned in claim 1.
  • the magnet has at least one notch in which the retaining element can engage, because this does not increase the outer radius of the magnet and carrier element.
  • An advantageous embodiment of the carrier element has a disc-shaped cross section.
  • Another advantageous embodiment of the carrier element has an annular cross section.
  • the magnet can advantageously be attached to the carrier element by placing the magnet on the carrier element and then deforming the retaining element in such a way that the magnet is held on the carrier element by positive and non-positive engagement, so that it is simple, quick and inexpensive magnetic fastening method is achieved.
  • Another advantageous way of attaching the magnet to the carrier element is to bend the retaining element by force so that the magnet can be arranged on the carrier element, and then to withdraw the force so that the retaining element then engages the magnet so that a simple, fast and inexpensive magnetic fastening method is achieved.
  • FIG. 1 shows a first exemplary embodiment of a magnetic holder designed according to the invention
  • FIG. 2 shows a radial cross section of FIG. 1
  • FIG. 3 shows a further exemplary embodiment of a magnetic holder designed according to the invention
  • FIG. 1 shows a magnetic holder 1 and FIG. 2 shows a radial cross section of FIG. 1.
  • four magnets 8 are arranged on a carrier element 5 of the magnet holder 1.
  • a magnet 8 is fastened to the carrier element 5 by four retaining elements 14, which are formed in one piece with the carrier element 5 and are plastically or elastically deformable.
  • the retaining elements 14 are, for example, hook-shaped.
  • a magnet 8 has, for example, four notches 16, in which the retaining elements 14 engage in order to fix the magnet 8 on the carrier element 5.
  • the retaining elements 14 already have the shape shown in FIG. 2 and are bent open for the application of the magnets 8. Instead of the magnet 8, other parts, such as a mirror for a light barrier, are attached to the carrier element 5.
  • the carrier element 5 can have a disk-shaped structure in the radial cross section or, as shown in FIGS. 1, 2, can have an annular structure.
  • the carrier element 5 is designed, for example, as in FIG. 1, so that it can be applied to a shaft 20.
  • Cross bars connect an outer ring with an inner ring.
  • the shaft 20 and the carrier element 5 have a center line 21.
  • Such a magnet holder is not only suitable for holding magnets on an outer peripheral surface 18 of the carrier element 5, but also on an inner peripheral surface.
  • Such a magnetic holder 1 is installed in an electric motor, for example, and forms a rotor there, for example.
  • the retaining elements 14 do not, for example, protrude beyond the outer boundary of a magnet 8. This is particularly important if the rotor is to have particularly small air gaps within a stator of an electric motor. in the
  • a recess 23 is provided, in which the magnet 8 is then located.
  • FIG. 3 shows a carrier element 5 without magnets 8.
  • the retaining elements 14 are not bent and form protruding from the peripheral surface 23 and from the center line
  • FIGS. 4 a to c show exemplary embodiments of magnets 8 for a magnet holder 1.
  • the magnets 8 are, for example, ring arc segments with, for example, the same thickness, which, for example, are square in plan view of the area with the notches 16.
  • the surface of the magnet 8 merges continuously into the notch 16 in the exemplary embodiment shown in FIG. 4a.
  • FIG. 4b shows a second exemplary embodiment of such a magnet 8.
  • FIG. 4c shows a magnet which has only one notch 16 on each edge, but which is made wider than a notch 16 as shown in FIG. 4a, b, so that a correspondingly wider retaining element 14 can attack a larger holding surface, which is sufficient great restraint.
  • the carrier element 5 can also be a laminated core, which is formed from individual laminates.
  • a punching tool When making one Sheet metal laminates by means of a punching tool are made of sheet metal laminates without projection 27 and with projection 27.
  • the different sheet metal laminates are stacked and packaged accordingly.
  • the attachment of magnets 8 on the carrier element 5 can be carried out in several ways.
  • the magnets 8 are inserted into the recess 23 and the projections 27 are then pressed into the notches 16 in the magnets 8.
  • the projections 27 are designed in such a way that, after being bent over by a corresponding form stamp in the notch, they bear positively on the surface of the magnet 8 and no longer protrude beyond the surface thereof.
  • Retaining element 14 (length, width, bend) is designed and adapted in such a way that the retaining element 14 and the notch 16 reliably withstand the loads which arise, for example, from rotation.
  • a further procedure for fastening the magnets 8 on the carrier element 5 can be such that the projections 27 have to be bent over (FIG. 2), then the magnet 8 is inserted into the recess 23 and then the force is exerted on the projections 27 Projections come to a positive and non-positive fit in the notch 16 of the magnet 8.
  • magnets for example, are those magnets which have been produced, for example, by hot extrusion, i.e. the notches can be made directly at the
  • Manufacturing process are attached, and do not have to be retrospectively, e.g. can be introduced by grinding.
