摘要： A bearing arrangement comprises a rolling element bearing assembly including a bearing cage. The bearing cage comprises an annular cage body having an inner surface defining a coaxial bore. The bearing cage has a plurality of circumferentially spaced pockets and each pocket houses a rotatable rolling element. A first annular skirt extends axially from a radially inner end of a first axial end of the cage body and at least one first support member extends radially and axially from the remote axial end of the first annular skirt to the radially outer end of annular cage body. The bearing cage is hollow and has a high stiffness to weight ratio. The bearing arrangement is particularly suitable for use for a planet gear of a planetary gearbox. The planetary gearbox may be for a gas turbine engine.

The inner peripheral surface (5b) of the large-diameter rim part (5) and the outer peripheral surface (7b) of the small-diameter rim part (7) 5 respectively have axial-direction inside portions (5c), (7c) overlapping with the pillar parts (10) in the axial direction and axial-direction outside portions (5d), (7d) not overlapping with the pillar parts (10) in the axial direction. A small-diameter annular member (2) is internally fitted in the axial-direction outside portion (5d) of the inner peripheral 10 surface (5b) of the large-diameter rim part (5). A large-diameter annular member (4) is externally fitted in the axial-direction outside portion (7d) of the outer peripheral surface (7b) of the small-diameter rim part (7).

摘要： A bearing cage for a rolling-element bearing includes a plurality of bearing cage segments configured to receive rolling elements in rolling-element pockets. Also included is at least one assembly wire, and each of the cage segments includes a coupling arrangement configured to thread the bearing cage segment onto the at least one assembly wire such that at least one rolling-element pocket is formed by two of the plurality of bearing cage segments adjacent in the circumferential direction that are threaded on the assembly wire. The bearing cage also includes an assembly device configured to convey an end of the assembly wire from an installation position to an axially far-side coupling arrangement of a bearing cage segment, through the axially far-side coupling arrangement of all bearing cage segments located on a bearing inner ring, and back again towards the installation position.

摘要： A retainer-equipped roller includes a retainer (12) having a pair of ring parts (14) separated in an axis O direction and column parts (15) arranged circumferentially at regular intervals so as to form pockets (22) and connect the pair of ring parts (14), and a plurality of rollers (11) arranged in the pockets. The roller (11) has a chamfered part (13) provided between a roller end face and a roller rolling surface (11t). The column part (15) is positioned on a radial outer side of a pitch circle PCD of the roller (11), and a distance between the circumferentially adjacent column parts (15 and 15) is smaller than a diameter of the roller (11). The pair of ring parts (14) has a pair of projection members (16) projecting such that their tip ends are opposed so as to come close to each other, in circumferentially the same position as the column part (15), and in a position on a radially inner side of the pitch circle PCD of the roller (11). The tip ends of the pair of projection members (16) abut on the chamfered parts (13) provided at both ends of the roller (11) and hold the roller between the pair of ring parts (14).

摘要： A drawn cup roller bearing includes: an outer ring including a raceway surface; a first rib formed at one end of the outer ring by being bent substantially perpendicular to the raceway surface; a second rib formed at the other end of the outer ring by being bent inwardly so as to be substantially parallel to the raceway surface; a cage including pockets for holding rollers, respectively; and an annular projection stopper which is projected radially outwardly and provided over an entire outer circumference at a pocket side position of an outer circumferential surface of the cage. An end surface of the cage abuts against a part of the first rib and the annular projection stopper is interposed between an end surface of the second rib and the rollers in a state that the cage is assembled into the outer ring.

摘要： A roller bearing cage for guiding rolling bodies in a rolling body bearing, which has multiple rolling bodies, two cage side elements, between which the rolling bodies are arranged, and which have multiple web appendages to guide the rolling bodies, and multiple connection elements that connect the two cage side elements. The azimuthal position of the connection elements defines a connection area. Exactly one connection element and at least one web appendage are arranged in a connection area. The connection element and web appendage are arranged in sections inside a radial interior of the respective cage side elements, the border of which is defined by the positions of the rotation axes of the rolling bodies.

摘要： A multi-part axial cage for a large diameter roller bearing, which has a metal strip which is connected to plastic cage windows. The metal strip is configured as a washer-ring-type flat cage and each cage window has a sealing element on the edge lying opposite the guiding edge. The element covering an axial gap is formed between the races of the roller bearing. The sealing elements of the individual cage windows overlap around the circumference.
