    Abstract: Disclosed herein is an air foil bearing capable of adjusting stiffness of single bumps by varying widths of the single bumps. Since the bumps have the same height in an initial stage, a wedging effect is implemented only when a load is applied thereto by an oil film. Therefore, the air foil bearing is advantageous in terms of height management thereof. In addition, it is possible to stably dampen shocks applied in the direction of rotation of a rotor, to improve a support capability, and to reduce shocks due to damping. Therefore, it is possible to enhance durability of the air foil bearing.

The large flange surface has an arithmetic mean roughness Ra of 0.1 ?m?Ra?0.2 ?m. The large flange surface further has a roughness curve skewness Rsk of ?1.0?Rsk??0.3, and a roughness curve kurtosis Rku of 3.0?Rsk?5.0. The tapered roller bearing is capable of realizing both stable rotation torque while the bearing is rotating at a low speed, and excellent resistance.

  • Publication number: 20200011376
    Abstract: A magnetic bearing having a first bearing ring and a second bearing ring arranged concentrically in relation to the first bearing ring. The first bearing ring and the second bearing ring are mounted so as to be rotatable with respect to each other about an axis of rotation by means of electromagnets. The first bearing ring has a first magnet row and a second magnet row. The magnet rows each include electromagnets arranged at a distance from one another in a circumferential direction of the first bearing ring. The electromagnets of the magnet rows are oriented such that they can each exert a magnetic force on the second bearing ring, which magnetic force is oriented transversely to the axis of rotation and transversely to a radial plane which is arranged perpendicularly to the axis of rotation. The disclosure further relates to a method for operating a magnetic bearing.

    Abstract: A frictionally locking shaft/hub clamping connection (1) having at least two cone clamping rings (4, 5) which bear against one another on their cone faces (4a, 5a) and can be pushed onto one another axially by way of clamping elements (6), the radial forces which are produced bringing about a frictionally locking connection between the shaft (2) and the hub (3). The cone faces (4a, 5a) of the clamping rings (4, 5) which bear against one another have a non-round cross section which differs from the circular shape.

  • Publication number: 20200011385
    Abstract: A free wheel assembly with front clutches comprising a hub sleeve rotatable on a hub pin and a cassette rotatable on the hub pin, a first annular body rotatable on the hub pin and comprising a first crown gear, a second annular body associated with the hub sleeve and comprising a matching second crown gear facing the first crown gear. The first annular body is axially movable relative to the second annular body between a motion transmission configuration and a free wheel configuration and coupling members operate between the first annular body and the cassette. In the free wheel configuration, rotation of the cassette relative to the first annular body forces the coupling members to axially translate the first annular body towards the second annular body, and magnetic members active on the first annular body and opposing the rotation of the first annular body with respect to the hub pin.
