    摘要: A roller bearing of the type having a flange on which thrust loads are received shows improved ability to form an oil film at the contact surface portions of the end surface of a roller and the flange. The contact surface portions are both inclined at an angle of not less than 0.1° and not more than 1.5° with respect to the radial direction, over the entire circumferences of the respective contact surface portions.

    摘要: A rolling contact bearing includes a shaft having a first radial elevation and a second radial elevation. A first inner ring has a first raceway for the rolling bodies to roll on, a first radial narrowing and a second radial narrowing, the first radial elevation and the first radial narrowing forming a first press fit, and, respectively, the second radial elevation and the second radial narrowing forming a second press fit. The shaft has a third radial elevation and a fourth radial elevation. A second inner ring has a second, radially outer rolling body raceway for rolling bodies to roll on, a third radial narrowing and a fourth radial narrowing, wherein the third radial elevation and the third radial narrowing forming a third press fit and, respectively, the fourth radial elevation and the fourth radial narrowing forming a fourth press fit.

    摘要: A bearing assembly includes a hub element or housing element which has an accommodating bore for at least one rolling-element bearing, the rolling-element bearing being disposed with its outer ring in a press-fit arrangement in the accommodating bore, and the outer ring having at least one first axial region along at least one raceway of the outer ring and at least one second axial region extending outside the raceway. To ensure a proper fit of the bearing ring in the hub or housing element over a wide range of operating temperatures, the receiving bore and the outer circumference of the outer ring are configured such that at the ambient temperature the radial clamping force between accommodating bore and outer ring in the first region is smaller than in the second region.

    摘要: A turbine generator includes a bearing device configured to rotatably support a rotor inside a housing. The bearing device separates an internal space of the housing from its outside. Communicating portions are formed in the bearing device. The communicating portions are formed in regions which are out of contact with lubricant. Each communicating portion establishes communication between the internal space of the housing and its outside.

    摘要: An inner raceway (3) having a rolling element raceway facing radially outward, for an angular contact bearing arrangement, and particularly an angular ball bearing arrangement, where a cylindrical surface which is situated at the furthest outward position radially is included as a seal seat. Such inner raceways are used in wheel bearing units, for example, which have an orbital rivet bond, which in turn can also form an end-face gearing (7). The orbital rivet bond and the axial extension (8) of the inner raceway form an annular gap (20) which leads to a configuration where a decoupling of loads from the inner raceway (3) prevents an undesired deformation of the same. In addition, advantages result from the sealing of the region of the orbital rivet bond and/or the end-face gearing (7) thereof.

    摘要: An assembly providing a first annular shield including a sleeve portion integral with a rotating member and with a flange portion, which radially extends to protrude from the first sleeve portion; a second annular shield having a sleeve portion integral with a stationary member and with a flange portion that radially extends to protrude on the opposite side of the sleeve portion of the first shield and facing the flange portion; and an annular seal, which the flange portion of the first shield ends with an L-shaped annular portion that protrudingly radially and axially extends out of an annular gap delimited between the rotating and stationary members to define an L-shaped channel in radial section having constant width and forming a first labyrinth seal; the channel leads into an annular recess, delimited between the second shield and a first lip of the annular seal without contacting the first shield.
