Abstract:
A squeeze film damper bearing assembly includes a bearing and a squirrel cage radially outward of and supporting the bearing. The squirrel cage includes a first piston ring groove, a second piston ring groove, and a first pocket connected to the first piston ring groove. The squeeze film damper bearing assembly also includes a first piston ring configured to fit into the first piston ring groove. The first piston ring includes a first end circumferentially spaced apart from a second end and an ear configured to fit into the first pocket to prevent the first piston ring from rotating in the first piston ring groove. The squeeze film damper bearing assembly also includes a second piston ring configured to fit into the second piston ring groove and a stationary housing radially outward of the squirrel cage.
