Abstract
This invention relates to a bearing arrangement for supporting a rotatable shaft relative to a support structure. The bearing arrangement comprises a first bearing having radially inner and outer races, the inner race being rotatable relative to the outer race in use, and a second bearing arranged such that the first bearing is mounted to the support structure via the second bearing. The second bearing may allow for deflection of the shaft supported by the bearing arrangement. The bearing arrangement may be applied to high speed thrust bearing applications, such as, for example, within a gas turbine engine.
Claims16
A bearing arrangement for supporting a shaft relative to a support structure, the shaft being rotatable about an axis and the bearing arrangement comprising:
- a first bearing having radially inner and outer opposing portions, the inner portion being rotatable relative to the outer portion in use so as to accommodate rotation of the shaft about said axis, and
- a second bearing mounted to said first bearing and arranged such that the first bearing is mounted to the support structure via the second bearing so as to allow displacement of the first bearing relative to said axis.
