  • Publication number: 20200408143
    Abstract: A turbocharger turbine rotor includes a rotor basic body, and moving blades configured without an outer shroud. The moving blades, forming a defined curvature region, merge into the rotor basic body with a defined, constant or variable curvature radius rf. On a first group of first moving blades, the following relationship applies to the curvature radius of the curvature region of the first moving blades: 2.5%?rf1*100/l?10%, wherein rf1 is the constant or variable curvature radius of the curvature region of the first moving blades and l the length of the first moving blades on a flow trailing edge. On a second group of second moving blades, the curvature radius rf2 of the curvature region of the second moving blades deviates from the curvature radius rf1 of the curvature region of the first moving blades on the damping side in a defined manner.

  • Publication number: 20200300115
    Abstract: A turbocharger includes a turbine and a compressor, each of which includes a rotor and a stator. At least one of the respective rotors and/or stators includes at least one interior flow passage at least partly or completely surrounded by a wall that provides cooling. The respective rotor and/or stator having the at least one flow passage is at least partly produced by additive manufacturing.

  • Publication number: 20200116025
    Abstract: A turbine guide apparatus for a turbine or a compressor with a rotor having a number of guide blades arranged on the rotor in the circumferential direction following one another at a non-equidistant, irregular interval ?i,i+1, wherein ?i,i+1 each defines the interval of two guide blades directly following one another in the circumferential direction.
