Resilient bearing mount with integral damper fluid passage for a geared turbofan engine
Abstract:
A gas turbine engine includes a bearing support ring with a first annular body and a second annular body disposed radially inward of the first annular body. A radial spring is connected to the first annular body and the second annular body. The gas turbine engine includes a frame with a case that extends around the first annular body. The frame includes an annular member connected to the case and positioned radially between the radial spring and the second annular body. A fluid port extends radially through the annular member. A seal is disposed around the annular member and forward of the fluid port. A first fluid passage extends through the case. A second fluid passage is formed between the bearing support ring and the frame and extends from the first fluid passage to the fluid port. A bearing outer race is disposed inward of the second annular body.
