摘要： A plain journal bearing (20) coupling a first component (21) to a second component (22). A pin (26, 27) passes through the first component (21) and the second component (22). A clamping bush (31, 32) surrounds the pin and has a cylindrical inner surface and a cylindrical outer surface. A clamping member (29a) is mounted on the pin and provides a clamping force to urge the clamping bush (31, 32) into clamping engagement with the first component. The bearing (20) has a primary slip path between the outer surface of the clamping bush (31, 32) and the second component (22) which is arranged to operate such that during normal operation of the bearing, when the first and second component rotate relative to each other, the second component (22) and the clamping bush (31, 32) rotate relative to each other about the primary slip path and the clamping bush (31, 32) remains in clamping engagement with the first component (21). The pin (26, 27) also has a cylindrical outer surface which provides a subsidiary slip path which is arranged to operate such that during degraded operation of the bearing (20), when the first (21) and second (22) component rotate relative to each other and the coefficient of friction of the primary slip path has increased to overcome the clamping force, the pin (26, 27) and the clamping bush (31, 32)or the pin (26, 27) and the first component (21) rotate relative to each other about the subsidiary slip path.

摘要： A bearing assembly for supporting a drive shaft of a ship wherein the shaft is generally to be supported by such bearing assembly in a horizontally extending position. The bearing assembly has a housing with a cylindrical shell mounted therein having a central bore with a longitudinally extending central axis. The shell has a set of circumferentially spaced staves to support the drive shaft. All of the staves are comprised of a slippery polymer alloy and project into the central bore of the shell. The staves are held in place by gripping members comprised of an elastomeric member compressed by a rigid plate.

摘要： A plain journal bearing (20) coupling a first component (21) to a second component (22). A pin (26, 27) passes through the first component (21) and the second component (22). A clamping bush (31, 32) surrounds the pin and has a cylindrical inner surface and a cylindrical outer surface. A clamping member (29a) is mounted on the pin and provides a clamping force to urge the clamping bush (31, 32) into clamping engagement with the first component. The bearing (20) has a primary slip path between the outer surface of the clamping bush (31, 32) and the second component (22) which is arranged to operate such that during normal operation of the bearing, when the first and second component rotate relative to each other, the second component (22) and the clamping bush (31, 32) rotate relative to each other about the primary slip path and the clamping bush (31, 32) remains in clamping engagement with the first component (21). The pin (26, 27) also has a cylindrical outer surface which provides a subsidiary slip path which is arranged to operate such that during degraded operation of the bearing (20), when the first (21) and second (22) component rotate relative to each other and the coefficient of friction of the primary slip path has increased to overcome the clamping force, the pin (26, 27) and the clamping bush (31, 32)or the pin (26, 27) and the first component (21) rotate relative to each other about the subsidiary slip path.

摘要： The invention regards a toroidal roller bearing (1), which comprises an outer ring (2), an inner ring (3) and a plurality of roller elements (4) interposed between the outer and inner ring (2, 3), wherein the toroidal roller bearing (1) allows for angular and axial displacement between said outer and inner ring (2, 3). Furthermore, the bearing (1) presents a cage (5) for holding the roller elements (4), wherein the cage (5) presents means (6) for axially guiding the roller elements (4) against at least one of the outer ring (2), inner ring (3) or a separate element (7) located outside the toroidal roller bearing (1).
