Claim Text:
1. A bearing structure comprising: a first bearing having a first inner race, a first outer race and a first set of rolling elements housed between the first inner race and the first outer race; a second bearing having a second inner race, a second outer race and a second set of rolling elements housed between the second inner race and the second outer race; a housing surrounding the first bearing; a first compliant element, the first compliant element fixedly connected to the first outer race, a rigid diaphragm having a radially inner end fixedly connected to the first outer race at a position spaced from the connection between the first compliant element and the first outer race, and a radially outer end flexibly connected to the housing, wherein the first compliant element, first outer race and rigid diaphragm at least partly define a pressure chamber; and wherein the first outer race is axially slidable relative to the second outer race such that an increase in pressure in the pressure chamber causes a change in axial spacing between the first and second outer races.
