Abstract
A bearing arrangement of a gas turbine engine includes a first bearing supportive of a shaft, and a second bearing axially offset from the first bearing. A first bearing support extends from a bearing housing to the first bearing, and a second bearing support extends from a bearing housing to the second bearing. One or more radial bearing supports including a plurality of radial spokes extend between the bearing housing and the second bearing. The spokes are configured to buckle under compression when radial loads at the second bearing exceed a predetermined force threshold. An axially-extending spoke foot extends from at least one radial spoke. The axially-extending foot is configured to contact the second bearing in the event of a tilt of the second bearing beyond a predetermined angle threshold, reducing the buckling force of the plurality of radial spokes below a second predetermined force threshold.
