Active system for bearing oil damper supply and vibration control

摘要

A bearing damping system includes a pump configured to pump a fluid. The system further includes a variable position valve having a plurality of open positions each configured to generate different pressures in the fluid downstream from the variable position valve. The system also includes a bearing assembly. The bearing assembly includes a bearing housing. The bearing assembly also includes a stationary bearing race positioned within the bearing housing. The bearing assembly also includes a rotating bearing race spaced apart from the stationary bearing race and configured to be attached to a rotating component. A bearing element is disposed between the stationary bearing race and the bearing housing. A fluid compartment is defined by the space between the bearing housing and the stationary race and is configured to receive the fluid from the second conduit.

1. A bearing damping system comprising:
a pump configured to pump a fluid through the system; a variable position valve connected to the pump by a first conduit and having a plurality of open positions each configured to generate a different flow of the fluid downstream from the variable position valve; and a bearing assembly connected to the variable position valve by a second conduit and comprising:
a bearing housing having an outer surface and an inner surface, the bearing housing configured to be attached to a stationary structure;a stationary bearing race having an outer surface and an inner surface and positioned within the bearing housing;a rotating bearing race having an outer surface and an inner surface spaced apart from the stationary bearing race and configured to be attached to a rotating component;a bearing element disposed between the inner surface of the stationary bearing race and the outer surface of the rotating bearing race; anda fluid compartment defined by the space between the inner surface of the bearing housing and the outer surface of the stationary race and configured to receive the fluid from the second conduit.
