Publication number: 20200355200Abstract: A turbo machine, having a housing and, an impeller received in the housing. The housing has at least two housing parts connected to one another via a flange connection. A first housing part of the housing parts has threaded bores for connecting screws. A second housing part of the housing parts connected to one another has through-bores for the connecting screws. The second housing part lies against the first housing part with a first face and screw heads of the connecting screws lie against an opposite second face of the second housing part. The through-bores of the second housing part on and adjacent to the second face have a smaller cross-sectional area than on and adjacent to the first face.Type: ApplicationFiled: May 6, 2020Publication date: November 12, 2020Inventors: Oswald Lôwlein, Matthias Strauss, Sebastian Spengler, Boris Thaser, Frank Griesshaber

Publication number: 20200300161Abstract: A turbocharger having a housing and a stator. The housing and/or the stator has an inner and an outer housing component. An inner section of the housing component lies directly against and covers a lateral section of the housing component. The lateral section and the inner section are formed such that they form a positive-locking connection, which fixes the inner housing component and the outer housing component against positional change along a longitudinal axis of the turbocharger and/or against a rotation about this longitudinal axis. The inner housing component and/or the outer housing component is at least partly produced by additive manufacturing.Type: ApplicationFiled: February 27, 2020Publication date: September 24, 2020Inventors: Stefan ROST, Sebastian SPENGLER, Boris THASER, Santiago UHLENBROCK, Stefan WEIHARD, Claudius WURM

Publication number: 20200191162Abstract: An auxetic material or auxetic structures in an exhaust gas turbocharger having a shaft and at least one compressor wheel arranged on the shaft, a turbine wheel and a housing in which the shaft, the compressor wheel, and the turbine wheel are arranged. At least one part of the housing includes an auxetic material with a negative Poisson's ratio.Type: ApplicationFiled: December 13, 2019Publication date: June 18, 2020Inventors: Stefan WEIHARD, Sebastian SPENGLER, Boris THASER, Lutz AURAHS

Publication number: 20200173361Abstract: A turbocharger, includes a turbine for expanding a first medium, a compressor for compressing a second medium utilising energy extracted in the turbine during the expansion of the first medium. The turbine housing and a compressor housing are each connected to a bearing housing arranged between the same. The turbine housing, and/or the compressor housing and/or the bearing housing form/s a stator-side assembly and/or receive/s a stator-side assembly, which serves for the lubrication, and/or heat conduction, and/or sealing. The respective stator-side assembly which serves for the lubrication, and/or heat conduction, and/or sealing, is produced by a generative manufacturing method.Type: ApplicationFiled: December 2, 2019Publication date: June 4, 2020Inventors: Sven BRANDT, Stefan STÖHR, Lutz AURAHS, Stefan ROST, Stefan WEIHARD, Santiago UHLENBROCK, Sebastian SPENGLER

Publication number: 20190293086Abstract: A radial compressor, with a compressor rotor, a compressor housing having a radially outer and a radially inner insert section, a main flow channel for supplying a medium toward the compressor rotor, a circulation chamber arranged radially outside of the main flow channel, which is separated from the main flow channel by a contour wall connected with the main flow channel via circulation openings to the insert section via struts extending into the circulation chamber. The main flow channel is bordered by the contour wall, and upstream from the contour wall by an upstream portion of the insert section. A suction element is arranged upstream from the compressor housing, whose radially outer portion adjoins the spiral housing section, and whose radially inner portion adjoins the upstream portion of the insert section. Adjoining surfaces of the suction element and the insert section lie on a cylindrical surface.Type: ApplicationFiled: March 21, 2019Publication date: September 26, 2019Inventors: Matthias STRAUß, Oswald LÖWLEIN, Sebastian SPENGLER, Boris THASER
