    摘要： A bearing assembly is disclosed, comprising: an outer race and a plurality of rolling elements associated with the outer race. An inner race adapted to receive a shaft therein is rotatably disposed within the outer race such that the plurality of rolling elements are disposed between the inner and outer races. A cylindrical extension forming a plurality of tabs symmetrically arranged around the entire periphery of the extension is adapted to engage the shaft. A clamp collar that is installable around the cylindrical extension is defined by a circular wall with at least one threaded opening extending through the circular wall. The threaded member extends through one of the threaded openings to make contact with and apply a biasing force on one of the plurality of tabs towards the shaft when the shaft is disposed in the inner race to secure the inner race on the shaft.

    摘要： A seal assembly is for sealing a space adjacent to a bearing and defined between an inner member and an outer member disposed about the inner member. The seal assembly includes an annular seal disposed about the inner member and having a sealing lip sealingly engageable with the inner member. An annular load ring is disposed within the outer member bore and has an inner circumferential surface defining a bore, the seal being disposed within the bore and coupled with the ring. A first axial end of the ring is disposed against the bearing outer ring, or a spacer disposed axially between the load ring and the bearing outer ring, and a second axial end is disposed against a radial surface of the outer member. The load ring is configured to support axial loading on, and to prevent axial displacement of, the bearing outer ring.

    摘要： A bearing arrangement rotatably supports a shaft of an aircraft engine. The bearing arrangement comprises a bearing having rolling elements disposed between inner and outer races. The inner race is affixed to the shaft. A decoupler normally structurally couples the outer race of the bearing to a stator structure of the engine. The decoupler is configured to release the bearing from the stator structure when subject to a predetermined critical load. A bumper is mounted to the stator structure and encircles the bearing. The bumper has a radially inwardly facing surface disposed in close proximity to a radially outer surface of the outer race of the bearing and defines therewith a radial gap to accommodate and constrain an orbiting motion of the rotor about the central axis of the engine after decoupling at the bearing. The bumper further has an axially forwardly facing surface which is axially spaced by a predetermined axial fore gap from a first flange projecting radially outwardly from a front end portion of the outer race of the bearing. The first flange of the outer race is axially trapped between the stator structure and the bumper. After decoupling, the bearing is free to axially and radially move within the radial gap and the axial fore gap.

    摘要： A bearing arrangement (30) comprises an inner support annulus (33), an outer support annulus (31), and a plurality of rollers (34) therebetween. At least one of the inner and the outer support annulus (33, 31) comprises one or more radially extending rigid supports (37) and one or more damping sectors (38a, 38b, 38c). The one or more rigid supports (37) are circumferentially interposed between one or more damping sectors (38a, 38b, 38c). Each damping sector (38a, 38b, 38c) comprises at least one damping member (39) comprising an elongate flexible member held rigidly at one or both ends thereof, such that vibrational movement of the inner or outer support annulus (33, 31) causes bending of the elongate flexible members (39).
