  • Patent number: 11901783
    Abstract: In a method for producing a winding overhang assembly for an electrical rotating machine, an insulating main body is produced at least partly from a dielectric material. Each of a plurality of conductors of a metal material is connected to the insulating main body via an intermediate layer, which is produced from a material which is different from the dielectric material of the insulating main body and from the metal material of the conductors and which is produced from silver, aluminum, antimony, magnesium, tin, zinc, lead, tantalum or from a mixture and/or from at least one alloy thereof. The conductors are hereby sprayed onto the intermediate layer by a thermal spraying method.

  • Patent number: 10549385
    Abstract: A component is produced in layers by laser melting. A molten pool is created in a bed of powder by a working laser beam. Further auxiliary laser beams are set to a power density that merely slows down the cooling of the material in one zone, but do not cause any renewed melting. In this way, the cooling rate of the microstructure can be set so that an advantageous structural formation develops. This allows for example the mechanical properties of the component produced to be advantageously improved without downstream heat treatments.

  • Publication number: 20190368822
    Abstract: Various embodiments include a cooling apparatus comprising: a thermal interface for a heat source to be cooled; a thermal pipe with a first phase change medium; and a latent heat store with a second phase change medium. The first phase change medium and the second phase change medium are contained in respective volumes separated from one another. Heat of the heat source, at the thermal interface, transfers into a heat absorption zone of the thermal pipe. A melting temperature of the second phase change medium is greater than an evaporation temperature of the first phase change medium.

  • Patent number: 10052821
    Abstract: A method uses a powder bed-based additive production of components such as laser melting. The interior wall of a hollow cylinder is used as a construction platform. Progressive production of the component is possible by rotating the hollow cylinder step-by-step in direction. This allows production of components without set-up times as the components can emerge from the powder bed as rotation continues and can be separated from the hollow cylinder by a separating device. The space requirement for the hollow cylinder in this arrangement is relatively small.

  • Patent number: 9670782
    Abstract: A method for creating a blade (11) for a turbo-engine and such a blade are disclosed. Components (19) of the blade are produced by an additive production method such as selective laser melting or fusion, while a main body (18) is produced by casting, for example. The blade components (19) may consist of a different material than the basic body (18). The components or body may carry functions such as serving as drainage slots (24). Expense related to the use of additive production methods occurs only for the components (19) in which a complicated geometry, for example, must be implemented. The remaining components in the form of the main body (18), comprising the blade (27), the blade foot (28) and the blade head (29), can be cost-effectively implemented as a cast part or a sheet metal part.

  • Patent number: 9187166
    Abstract: An elongated supporting pillar for a high-strength structural component is designed to absorb bending forces that act transversely to a longitudinal direction of extension of the supporting pillar. The supporting pillar comprises a wall which at least partially encloses an elongated cavity of the supporting pillar. A reinforcement structure is arranged within the cavity and transversely to the direction of longitudinal extension in such a manner that the reinforcement structure can absorb at least some of the bending forces. The reinforcement structure is designed integrally with the wall, wherein both the wall and the reinforcement structure comprise a meltable material. The supporting pillar has a conical shape, and wherein a first end of the supporting pillar is wider than a second end of the supporting pillar.

  • Publication number: 20140131921
    Abstract: A component is manufactured by selective laser melting by a laser having an intensity profile set largely constant by a diffractive optical element, so that the treatment surface which has occurred as a result of this profile is melted uniformly on the surface of the component. Thermal load peaks, such as occur due to an intensity maximum of an unshaped laser, can therefore be advantageously avoided. Moreover, the treatment surface may, for example, have a square shape, so that, in the case of rectangular components, it becomes simpler to produce the corners of the cross section to be manufactured. Overall, as a result, components having improved surface quality can be produced. The system is equipped with suitable optics for generating the intensity profile described.
