A differential squeeze film damper bearing assembly (50) for a gas turbine engine (10) that includes a high-pressure compressor (14), a high-pressure turbine (18), a first shaft (31) coupled between the high-pressure compressor and the high-pressure turbine, a fan assembly (12), a low-pressure turbine (20), and a second shaft (32) coupled between the fan assembly and the low-pressure turbine, the turbine using the first shaft. The differential squeeze film damper bearing assembly includes an inner race (52) coupled to first shaft rotatable in a first direction, an outer race (54) coupled to the second shaft rotatable in a second opposite direction, and a plurality of bcarings (56) coupled between the inner and outer races. |
