Abstract
A squeeze film damper bearing assembly includes a bearing and a spring cage that receives and surrounds the bearing. The spring cage has an inner diameter and an outer diameter. The outer diameter has an outer surface that defines a first circumferential channel recessed within the outer surface that is axially spaced apart from a second circumferential channel recessed within the outer surface and at least one axial anti-rotation chamber that interconnects the first and second channels. The assembly includes a first piston ring received in the first channel and a second piston ring received in the second channel. The assembly includes at least one anti-rotation member received within the at least one axial anti-rotation chamber that cooperates with the first piston ring and the second piston ring to inhibit a rotation of the first piston ring and the second piston ring relative to the outer surface.
