Abstract
In a gas turbine engine including first and second differentially rotating members coaxial with each other, a low pressure region disposed about the first and second differentially rotating members, and an annular gas flowpath disposed within the first and second differentially rotating members defining a high pressure region, a method and apparatus for preventing fluid leakage between the first and second rotating members. An annular carrier is coupled to the first rotating members such that the annular carrier is coaxial with the first rotating member. The annular carrier is sandwiched between a first race and a second race with the first and second races coupled to the second rotating member. The second race is urged toward the first race such that leakage of a fluid from the high pressure region to the low pressure region is not substantially increased by frictional wear of any of the annular carrier, first race and second race.
