Definitions
- Such composites between two or more joining partners are often exposed to high mechanical and / or thermal stresses.
- Such rotors are often operated at high speeds, for example, over 5000 revolutions per minute. Along with this, correspondingly high centrifugal forces are imposed on the composite.
- each bag must be controlled individually with a dispensing needle to dose the adhesive.
- the dosage is difficult due to dimensional tolerances of the bag. If too little adhesive is filled into a pocket, the magnet is not completely enveloped, so that gaps can form between the laminated core and the magnet, in which corrosion can form. On the other hand, if too much adhesive is used, the excess adhesive fabric from the gap between the pocket and the carrier body and must be laboriously removed so that the finished rotor has no local adhesive accumulation in the region of the pocket opening.
- Another problem is that the adhesive shrinks strongly during curing, so that tensions can occur and the adhesive bond breaks at high speeds.
- the object of the present invention is to provide a simple method for producing a firm and permanent connection between two or more joining partners.
- the joining partners are initially provided. Thereafter, a lacquer layer is applied to the first joining partner.
- This lacquer layer can completely or partially cover the surface of the first joining partner.
- the application of the lacquer layer on the first joint partner can be done for example by dipping, spraying or brushing.
- the second joining partner can have a depression which is provided to receive the first joining partner provided with the lacquer layer in whole or in part.
- the first joining partner provided with the lacquer layer is introduced completely or at least partially into the depression of the second joining partner.
- the recess can be designed so that it is adapted to the shape of the first joining partner, ie that remains between the second joining partner and the painted and completely or partially introduced into the recess first joining a gap whose width is a predetermined value, for example to to 1 mm at any point of the gap.
- the time of introduction of the first joining partner in the recess may be selected so that the paint layer is in B-state or C-state. In the B state, there is a partial crosslinking of the lacquer layer, whereby the lacquer has not yet completely cured. Finally, in the C-state, the lacquer layer is completely cured.
- the arrangement comprising the second joining partner as well as the lacquered and completely or partially introduced into the recess first joining partner is now impregnated with a impregnating resin.
- the impregnating resin can penetrate into recesses, recesses and gaps.
- the impregnating resin penetrates into a gap existing between the first joining partner and the second joining partner.
- the impregnation process at a reduced ambient pressure, for. B. at an absolute pressure of less than 1 hPa.
- a reduced ambient pressure can be achieved for example by means of a rotary vane oil pump.
- the viscosity of the impregnating resin is reduced at least until the first joining partner and the second joining partner are sufficiently firmly joined together.
- the impregnating resin can still be liquid.
- the outflow of the impregnating resin can by Capillary forces, as they exist between adjacent sheets of the laminated core, and / or by one or more closure elements, for example by rubber mats, which cover existing recesses, recesses and gaps are prevented.
- the lacquer layer applied to the first joining partner is produced from a special lacquer composition which enables the solid bond between the first and the second joining partner.
- the paint composition comprises an epoxy resin mixture, a curing accelerator, an epoxy-functional silane-based adhesion promoter and a solvent, wherein the epoxy resin mixture 10 wt% to 94 wt% of at least one solid epoxy resin having an epoxide number up to 2 Eq / kg, 1 wt% to 50 % by weight comprising at least one solid multi-functional epoxide resin with an epoxide number> 4 Eq / kg and 5 wt% to 40 wt% of a phenolic and / or Kresolnovo- Laks having a melting point of> 30 0 C.
- Suitable solvents for the paint are, for example, aliphatic and aromatic hydrocarbons, ethers, esters, glycol ethers, alcohols, ketones and / or mixtures of two or more such substances.
- the painting of the components themselves takes place in a conventional manner by brushing, Dipping, spraying, spinning, casting or other processes, wherein the spraying method is preferably used both in continuous and in the bulk material process due to the geometry of the parts to be painted. For this reason, it is expedient if the solids content of the paint is not too high.
- the solids content of the paint may be at most 50% by weight or between 10% by weight and 20% by weight.
- the epoxy resin mixture contains from 1% by weight to 80% by weight of a solid epoxy resin having an epoxide number of 1 Eq / kg to 2 Eq / kg.
- a resin for example, a resin may be used, which has a viscosity of, for example, 50 mPa-s to 1000 mPa ⁇ s or, for example, from 200 mPa-s to 300 mPa ⁇ s at a temperature of 25 ° C, for a long time, eg 1 month, is stable on storage and in which the curing can be started by increasing the temperature.
- a suitable impregnating resin comprises a resin component, a hardener component and optionally a curing accelerator.
- the resin component is, for example, a liquid at 20 0 C bisphenol A epoxy resin, a liquid at 20 0 C bisphenol F epoxy resin, or a liquid at 20 0 C mixture thereof.
- impregnating the impregnating resin 8 can be located from the outside in between the adjacent plates 21, 22, 23, 24, 25, 26 intermediate spaces 29 and in between the painted magnet 1 and the sheets 21, 22, 23, 24, 25, 26 located Column penetrate, so that the composite is completely soaked substantially without air bubbles.
