Hydrodynamic bearing with reduced temperature sensitivity |
摘要 |
A self-lubricating hydrodynamic spindle bearing comprising a stationary shaft including a conical, inwardly tapered surfaces extending axially form outer regions of the shaft toward a center connecting region of the shaft, a rotatably mounted sleeve surrounding the shaft and including surface regions flared axially inwardly toward a center region of the sleeve, the tapered surface regions and the flared surface regions defining a bearing gap for the hydrodynamic bearing, the sleeve defining a connection region adjacent the connecting region between the tapered surfaces of the shaft, the connection region including a tube collapsible in response to a change in internal pressure in the connection region to stabilize stiffness and power consumption in the bearing.
