  • Blower wheel
    Patent number: 11421704
    Abstract: A blower wheel having a plurality of blower wheel blades arranged in a blade ring, which are connected to a disc covering the blower wheel blades, at least in sections, on at least one axial side, wherein a connection between the blower wheel blades and the disc determines a transition geometry, which has a rounded curve of a quadratic function when viewed in the cross-section, at least on one side of the blower wheel blades, particularly a side facing radially inward with respect to an axis of rotation of the blower wheel.
    Type: Grant
    Filed: June 5, 2018
    Date of Patent: August 23, 2022
    Assignee: ebm-papst Mulfingen GmbH & Co. KG
    Inventors: Erhard Gruber, Jens Müller, Alexander Konzal
  • Fan wheel disc and fan wheel
    Patent number: 10920786
    Abstract: A fan wheel disc has at least one region that extends in a curved manner, at least in some sections, from radially inside to radially outside. A blade attachment surface is formed at least in some sections. The blade attachment fixedly connects an axial end side of at least one fan wheel blade. The blade attachment surface extends, at least in some sections, within the curved region of the fan wheel disc within a two-dimensional connecting plane.

  • Connecting element
    Patent number: 10662972
    Abstract: A connecting element (1) interacting with a fan blade (50) to transfer torque of a drive to the fan blade (50). An attachment portion (2) connects the connecting element (1) with the fan blade. The attachment portion (2) forms an outer edge portion (4) adjoining the outer contour of the connecting element (1). The attachment portion (2) cross-sectional shape is designed to taper toward the outer edge in at least some portions.

  • Ventilator wheel and ventilator
    Patent number: 10590949
    Abstract: The invention relates to a ventilator wheel which is produced in the form of a radial or a diagonal ventilator wheel, and comprises a bottom disc and a plurality of ventilator blades arranged, on said bottom disc, so as to be distributed about an axial rotational axis, said bottom disc comprising a circumferential radial outer edge section that, when viewed in cross-section, extends in a curved shape in at least some sections and thus forms an elliptical transition of said bottom disc from a radial extension into an axial extension.
