  • Patent number: 11338350
    Abstract: A method for permanently fastening a cam on a cam carrier may involve positioning the cam on the cam carrier in a predefined axial and angular position. By way of the positioning, an end face of the cam carrier is aligned with an end face of the cam. The method may also involve positioning a cam segment formed by the cam carrier and the cam in an assembly device. The cam carrier may then be deformed such that the cam is secured at least in a form-fitting or force-fitting manner against movement in an axial direction on the cam carrier. A deformation tool of the assembly device may be advanced in an axial direction onto the end face of the cam carrier, and the cam carrier may be deformed such that material of the cam carrier is forced outward in a radial direction against the cam.

  • Patent number: 10711665
    Abstract: A camshaft may comprise a main shaft, on which at least two sliding cam pieces are accommodated in a rotationally fixed and axially displaceable manner, wherein the sliding cam pieces each comprise a carrier tube, on which are seated cam groups each comprising at least two cam tracks for valve-control purposes, as well as an adjustment element that can be brought into operative connection with an actuator for axial displacement of the two sliding cam pieces. A method for assembling such a camshaft may involve providing a module body with bearing bridges that receive the camshaft in a rotatable manner, inserting a first sliding cam piece into a first bearing bridge, connecting the first sliding cam piece to the adjustment element, inserting a second sliding cam piece into a second bearing bridge, and connecting the second sliding cam piece to the adjustment element with the aid of an axial adjustment distance of at least one of the sliding cam pieces in the bearing bridges.

  • Patent number: 10557381
    Abstract: The invention relates to a clamping nest for positioning a component on a shaft, and joining it thereto. The component here has a central part with a circular-cylindrical aperture for accommodating the shaft. The clamping nest has a fork-shaped region for accommodating the component, wherein the fork-shaped region comprises a plurality of clamping elements, which secure the angled position of the component within the fork-shaped region. The fork-shaped region also comprises two opposite bearing surfaces, which secure the axial position of the component in a form-fitting manner in both axial directions.
