  • Patent number: 11965549
    Abstract: An unbalanced shaft is provided that has a center of mass eccentric to its rotational axis to generate a shaft unbalance. The unbalanced shaft includes a bearing journal having a variable width throughout its circumference, and a multi-row cage having rollers which roll on inner raceways arranged on an outer lateral surface of the bearing journal. The rollers and inner raceways define a load zone, within which a width of each of the inner raceways is greater than an effective length of the rollers idling thereon. At least one of the inner raceways, which extends circumferentially for 360 degrees, has a width throughout that is greater than an effective length of the rollers rolling thereon. For sections outside of the load zone, at least one of the inner raceways has a width less than the effective length of the rollers that roll thereon.

  • Patent number: 11913415
    Abstract: The disclosure relates to a tappet for acting on a pump piston of a high-pressure fuel pump of an internal combustion engine. The tappet includes a tubular housing, and at the upper annular end face of the tubular housing, two surfaces which are indented relative to the outer casing of the housing and comprise a pin that supports a cam roller, lie diametrically opposite each other. An upper end face of a transverse beam lies against axial inner end faces of the two surfaces. A transverse beam lower end face, which faces a lower annular end face of the housing, is provided with a pin, which protrudes from the housing and is surrounded by a spring plate supported against the inner casing of the housing. A sleeve-like inner collar of the spring plate guides the unstepped pin.

  • Patent number: 11898525
    Abstract: The disclosure relates to a roller tappet for a high-pressure fuel pump. The roller tappet includes a housing that accommodates a cam contact roller next to a drive-side annular face of the housing. A bridge piece sits on an inner lateral surface of the housing, after the cam contact roller, as viewed from the drive-side annular face. An outer end face of the bridge piece has a rest for a pump piston. A separate adapter bolt protrudes from the rest beyond the output-side annular face of the housing; an end face of the adapter bolt, remote from the bridge piece, serves as a direct rest for the pump piston. An annular disc sits next to the output-side annular face of the housing, and the bore of said annular disc surrounds and retains the adapter bolt.

  • Patent number: 11866155
    Abstract: An actuator arrangement for a fixed leading edge member of an aircraft wing. The fixed leading edge member has an inner cavity defined by the outer skin and ribs. The actuator arrangement comprises at least one geared rotary actuator which moves relative to the other parts along a circular arc section during extending and retracting of the high-lift device between a fully retracted position and a fully extended position. In the fully retracted position, the actuator is predominantly accommodated within the inner cavity and in the extended position the actuator is predominantly positioned outside the inner cavity, preferably protruding through a D-nose cut-out.

  • Patent number: 11549575
    Abstract: A roller tappet for a fuel pump includes an integral and hollow-walled guide housing, which has a drive-side edge that encloses a roller mounted on a pin. The ends of the pin are seated in openings in arranged in indented flat surfaces that originate from the drive-side edge and are diametrically opposite each other. An output-side edge of the guide housing has a bridge piece that extends continuously from an inner wall of the one of the flat surfaces to an inner wall of the other flat surface. The bridge piece projects beyond the inner wall towards the outer wall of the particular flat surface, and the output-side outer face of the bridge piece has a contact surface for a pump piston. The flat surfaces are completely continuous from the drive-side edge to the output-side edge of the guide housing.

  • Patent number: 11280384
    Abstract: A balance shaft is proposed that includes: i) an unbalance shaft having an unbalance section and an adjacent bearing pin having a cylindrical partial circumference which is oriented towards the shaft imbalance; ii) a bearing ring which surrounds the bearing pin and bears against the cylindrical partial circumference and delimits a free space with a bearing pin back radially opposite thereto; and, iii) a clamping element which is clamped in the free space and clamps the bearing ring radially against the cylindrical partial circumference. The clamping element is intended to secure the bearing ring against axial sliding on both sides on the bearing pin, and the clamping element is connected in an axially interlocking manner to the unbalance shaft on one side and to the bearing ring on the other side.

  • Patent number: 10774692
    Abstract: A tappet is proposed, for a fuel pump or for a valve timing gear, in each case of an internal combustion engine, comprising a hollow-cylindrical housing, which includes two separate portions lying in line one after the other, which are fitted together in a region of their facing inner faces and are permanently connected to one another by way of a joint. The tappet has a roller on its driving side and an abutment for a follower part on its driven side, which abutment is formed on a separate insert. The abutment is radially supported on the housing in the fitted-together region of the two portions, wherein the insert has a middle annular collar, from which on the one hand a sleeve portion protrudes in the direction of the driving side and on the other hand a dome-like attachment protrudes towards the driven side.
