    摘要： A tapered roller bearing (1) has inner and outer races (2, 4) and tapered rollers (6, 8) organized in at least two rows, with the rollers of the one row being generally aligned with the rollers (6, 8) in the other row. The large ends of the rollers (6, 8) are presented toward each other so that the forces which urge the rollers (6, 8) of either row up their tapered raceways (2, 4) are resisted by the rollers (6, 8) of the other row. The end faces of the aligned rollers (6, 8) in the two rows contact each other or else contact intervening elements such as cylindrical rollers or a separating disks. The geometry of the rollers (6, 8) and the raceways (2, 4) along which they roll are such that, when one race rotates relative to the other race, pure rolling contact exists between the side faces of the rollers (6, 8) and the raceways (2, 4) and pure rolling contact also exists at the end faces of the rollers (6, 8). Moreover, the lines of contact for the aligned rollers of any set are synchronized and the rollers (6, 8) are stable. Thus, the rollers (6, 8) remain in position within the bearing and the aligned rollers (6, 8) of any set track each other.

    摘要： The package bearing (A) for coupling a road wheel (C) to the suspension system of an automotive vehicle includes a nonrotatable outer bearing ring (12) having flanges (20) along which it is attached to the suspension system, a rotatable inner bearing ring (14) located within the outer ring (12) and having a flange (72) to which the road wheel (C) is attached, and tapered rollers (16, 18) arranged in two rows between the outer and inner rings (12, 14). The rollers (16, 18) contact the rings (12, 14) along inboard and outboard raceways (26, 28, 46, 48) that are likewise tapered, their large ends being at the ends of the two rings (12, 14). The large ends of rollers (18) on the outboard row move along a rib at the flange (72) on the inner ring (14), while the large ends of the rollers (16) of the inboard row move along a rib ring (60) that is formed as a separate element and subsequently connected to one of the rings (12, 14). Between its inboard and outboard raceways (46, 48) the inner ring (14) has a cylindrical intervening surface (50), the diameter of which exceeds the largest diameter on the inboard raceway (46) of the inner ring (14). This enables an encoder ring (52) to advance over the inboard raceway (46), and to be pressed over the intervening surface (50) to its final position. Thereafter the rib ring (60) is secured against one of the rings (12, 14) at the large end of the inboard raceway on that ring. During assembly, the rollers (16) of the inboard row are likewise advanced over the large end of the inboard raceway (46) for the inner ring (14), all while confined in a cage (94) - but the cage (94) has breaks in its small end ring to enable it to expand and accommodate the large end of the raceway (46). The outer ring (12) carries a sensor (34) which monitors the encoder ring (52), producing an electrical signal, the frequency of which reflects the angular velocity of the encoder ring (52). Seals (96, 98) close the annular space between the bearing rings (12, 14) at the inboard and outboard ends of the rings (12, 14).

    摘要： A compound ball-bearing includes a spindle (1) surrounded by a sleeve (2) in an inner surface of which two outer races (4,8) are formed. A first row of balls (5) run between one of the outer races (4) and a first inner race (3) formed in a first part (1a) of the spindle (1) and a second row of balls (9) run between the other outer race (8) and a second inner race (7) formed in an inner ring (6) mounted on a second part (1b) of the spindle (1). The spindle (1) is integrally formed in one piece with a hub (11) or a base of a motor. The spindle (1) may be stepped and the first part (1a) may have a larger diameter than the second part (1b).

    摘要： A package bearing (A) includes outer and inner rings (2, 4), provided with opposing raceways (10), and rolling elements (6) located between the raceways (10). The inner ring (4) has a flange (30) which projects outwardly past one end (24) of the outer ring (2) and is provided with a radially directed sealing surface (34) that is located opposite the end (24) of the outer ring (2). Here the outer ring (2) is fitted with a seal (B) including a case (50) that is pressed over the outer surface (22) of the outer ring (2) and an elastomeric seal element (52) having lips that bear against the sealing surface (34) on the flange (30) of the inner ring (4) to establish a dynamic fluid barrier. The case surrounds (50) the seal element (52) to protect it from stone impingement. The seal (B) is large enough to pass over the nearby set of rolling elements (6) in the bearing (A) and thus does not interfere with assembly of the bearing (A).

    摘要： La présente invention concerne la fraise (10; 10') d'une tête de forage, un moyeu constituant une partie de ladite fraise, ainsi qu'un procédé de fabrication d'un tel moyeu. La fraise (10; 10') est montée rotative dans un étrier, dans la tête de forage. Un roulement à rouleaux est placé entre l'arbre (11, 11') et le moyeu (18; 18') de la fraise. Pour que la résistance de portée des fraises soit améliorée, les voies de roulement extérieures (17; 17'a, 17'b) des rouleaux (15, 15'a, 15'b) du roulement à rouleaux font partie intégrante du moyeu. Selon le procédé de fabrication du moyeu (18; 18') les parties dudit moyeu qui ne doivent pas subir un traitement de durcissement sont laissées à l'état non fini ou recouvertes d'une couche empêchant la carburation. Le moyeu peut donc avoir des parties possédant différentes propriétés pour pouvoir satisfaire aux tolérances et aux spécifications.

    摘要： It is required that large rings such as slewing rings applied in (off-) shore cranes are regularly inspected on defects e.g. cracks appearing in critical zones. Such an important inspection zone concerns the bearing arrangement (2, 5, 7; 3,6,8). To avoid the costly dismounting and mounting work of said rings for inspection it is proposed to install ultra-sonic probes of standard types in the housings (10) of slewing rings (4). During rotation of said ring scanning of the critical zones (2, 14 and 3, 18) by the (opposite) arranged probes in the housing (15 and 10 resp.) can be effected.
