Abstract
A tilting pad journal bearing (2) comprises a bearing shell (4) having a substantially cylindrical inner surface and at least three bearing pads (5, 6, 7) extending around the inner surface of the bearing shell in a substantially circumferential direction. Each of the pads (5, 6, 7) is arranged for pivotal movement relative to the bearing shell (4) by a substantially spherically-extending surface (8, 9, 10) on the pad engaging a mating substantially spherically-extending surface (11, 12, 13) associated with the bearing shell. At least one of the substantially spherically-extending surfaces (11) associated with the shell (4) is provided on a member (14) so mounted in or on the bearing shell as to be capable of radial movement relative to the shell and a spring is provided for urging the member radially inwards.
