Abstract
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).
Claims10
A bearing arrangement comprising:
- an inner support annulus, and outer support annulus, and a plurality of rollers therebetween, at least one of the inner and the outer support annulus comprising one or more radially extending rigid supports, and one or more damping sectors, the one or more rigid supports being circumferentially interposed between one or more damping sectors;
- each damping sector comprising a plurality of spaced elongate damping members, each damping member of at least a first damping sector of the one or more damping sectors comprising an elongate flexible member held rigidly at one or both ends thereof and having a long axis extending only in a radial direction between the two ends, such that vibrational movement of the inner support annulus or the outer support annulus causes bending of the elongate flexible members, and wherein the rigid supports are rigid relative to the elongate flexible members.
