Abstract
A radial deflecting support member interposed between the damper support and the thrust bearing transmits the thrust loads and permits the use of an oil damper in a thrust loaded environment. The radial deflecting support has a spring rate that is at least equal to or lower than the damper support, so that when the radial deflecting support bottoms out the radial load will be absorbed by the damper support.
Claims6
For a thrust bearing rotatably supporting a shaft having a rotor developing thrust, support means having an annular portion concentric to and spaced from said thrust bearing, a radially flexible support means mounted between said thrust bearing and said support means normally supporting said thrust bearing, said radially flexible support means having a concentrically disposed annular portion defining between its outer diameter and the inner diameter of the annular portion of said support means a cavity for supporting an oil film for damping out vibration manifested by said shaft being transmitted thereto through said radially flexible support means and means securing said radially flexible support means and said support means so that thrust loads are transmitted to said securing means through said radially flexible support means.
