  • Publication number: 20220389955
    Abstract: A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, the bearing unit including a stationary bearing ring and a rotatable bearing ring that are rotatable with respect to each other. The rotatable bearing ring is fixedly connectable to the rotating component, and the stationary bearing ring is mountable in the stationary component in a rotationally fixed but axially displaceable manner. A connector is provided between the stationary bearing ring and the stationary component to connect the bearing ring to the stationary component in an axially displaceable but substantially rotationally fixed manner, and the connection is provided by a combination of a friction fit and an interference fit acting in the circumferential direction.

  • Publication number: 20210375787
    Abstract: The present disclosure is directed to a lead frame design that includes a copper alloy base material coated with an electroplated copper layer, a precious metal, and an adhesion promotion compound. The layers compensate for scratches or surface irregularities in the base material while promoting adhesion from the lead frame to the conductive connectors, and to the encapsulant by coupling them to different layers of a multilayer coating on the lead frame. The first layer of the multilayer coating is a soft electroplated copper to smooth the surface of the base material. The second layer of the multilayer coating is a thin precious metal to facilitate a mechanical coupling between leads of the lead frame and conductive connectors. The third layer of the multilayer coating is the adhesion promotion compound for facilitating a mechanical coupling to an encapsulant around the lead frame.
