    摘要: The invention relates to an angular contact roller bearing (1) which is embodied as multi-row ball roller bearing and which is composed essentially of an outer bearing ring (2) and an inner bearing ring (3) as well as of a plurality of ball rollers (5, 6) which are arranged between the bearing rings (2, 3), are held at equal distances from one another by a bearing cage (4) and, are arranged in at least two rows (7, 8) vertically offset one next to the other and each have two side faces (9, 10, 11, 12) which are flattened off symmetrically from a basic spherical shape. The ball rollers (5, 6) in the two rows (7, 8) roll here with running faces (13, 14) in groove-shaped raceways (17, 18, 19, 20) which are respectively adjacent to one another, are formed in the outer and the inner bearing rings (2, 3), have pressure angle axes (21, 22) extending parallel to one another and are each arranged adjoining one another in such a way that the respectively adjacent ball rollers (5, 6) of the two rows (7, 8) are arranged directly one next to the other with their side faces (10, 11) which point toward one another. According to the invention, the adjacent ball rollers (5, 6) in the two rows (7, 8) are respectively arranged on a common rotational axis (23, 24) which extends at right angles to the pressure angle axes (21, 22), and said ball rollers (5, 6) have diameters (d-i, d2) and widths (bi, b2) which are dimensioned in such a way that envelope cones (25, 26) which form tangents with all these ball rollers (5, 6) at their diameters (di, d2) are arranged with their cone tips (27, 28) precisely at the intersection point (SR) of the common rotational axes (23, 24) with the bearing longitudinal axis (29).

    摘要: The present invention provides a new bearing device of free rolling parts. According to the basic embodiment the bearing device is comprised of: an inner race, an outer race, two rows of rolling parts wherein each rolling part is in not in a contact with two adjacent rolling parts in the same row and in contact with rolling parts of at least one adjacent row and/or with the surface of one of the races. The bearing structure is designed to create orbital eccentricity between the inner race and the outer race. When a load is applied on said bearing it is equally distributed over all rolling parts. Furthermore, the load applied on said bearing decrease the orbital eccentricity wherein minimum limit of orbital eccentricity is maintained through the working process. The device engagement of rolling parts is slack-free.

    摘要: According to this double row tapered roller bearing apparatus, an integral outer ring (2) is provided with oil vents (20) which extend from an inner peripheral face (17) in an area outward in an axial direction than a rolling face (2B) on which an axially outward row of conical rollers (7) rolls and passes through an outer peripheral face (18). Therefore, a portion of lubricating oil supplied from oil supply holes (13) in the integral outer ring (2) passes the oil vents (20) via the axially outward row of the conical rollers (7), and will be returned to a space in a housing (1) by way of a channel (31) in the housing (1). In conclusion, a circulating path of the lubricating oil through the outward row of the conical rollers (7) can be formed by the oil vents (20).

    摘要: Compound ball bearing including a shaft (1) journalled for rotation relative to a sleeve (2) with first and second outer raceways (5a, 5b) formed in an inner surface thereof by means of first and second rows (6a, 6b) of ceramic balls. The first row (6a) of balls runs round a first inner raceway (3a) formed in an inner ring (4) which is connected to the shaft (1) under an axial pre-load and the second set (6b) run round a second inner raceway (3b) formed around the shaft (1). A squeeze ring (8) axially positioned between the rows (6a, 6b) of balls, is press fitted to a thin walled portion (7) of the sleeve (2) to deform it inwardly at ambient temperature. The co-efficient of thermal expansion of the sleeve (2) is a least similar to that of the squeeze ring (8) so that reduction of the inward deformation resulting from an increase in bearing temperature counteracts increased bearing play which would develop without the squeeze ring (8).

    摘要: A bearing support structure is disclosed for a turret (10A) mounted for rotation within a well (50A) of a moored vessel. The bearing support structure has a turret bearing assembly (900A) which may tilt about a tilting axis (783A) relative to a lower bearing support structure (764A) mounted on the vessel. The turret bearing assembly (760A) has a retainer ring (794A) below a peripheral slot (782A) in a turret ring (102A); a segmented key (596A) fits in slot (782A). The retainer ring (794A) is supported on an annular abutment (780A) on turret ring (102A). A filler material (781A) is provided in an annular space or clearance between turret ring (102A) and retainer ring (794A) to tighten the joint therebetween. A construction method is also disclosed for first placing a mooring turret in the well of the vessel and later installing a bearing assembly between the vessel and the turret by lowering it over the top of the turret.

    摘要: La présente invention concerne un roulement à billes à contact oblique qui peut porter dans les deux sens axiaux et qui comporte des couronnes à billes (4, 5) décalées l'une par rapport à l'autre dans le sens axial, une bague de roulement extérieure (1) d'une seule pièce et deux bagues de roulement intérieures (2, 3) dont les faces sont contiguees. Des gorges de roulement (4a, 5a, 4b, 5b) sont ménagées sur les épaulements des bagues de roulement intérieures (2, 3) et de la bague de roulement extérieure (1). Ce roulement à billes à contact oblique est caractérisé par le fait que l'une au moins des deux bagues de roulement intérieures (2, 3) est associée au moins à deux couronnes à billes (5, 6). Le diamètre de ces couronnes augmente graduellement à partir d'un plan de joint (8) entre les faces des bagues de roulement intérieures (2, 3). Ce système permet d'augmenter considérablement l'indice de portée en n'augmentant que légèrement l'encombrement total.
