Fluid dynamic bearing with an immiscible fluid barrier |
摘要 |
A fluid dynamic bearing with an immiscible fluid barrier deposited on the bearing oil is disclosed. One embodiment provides the fluid dynamic bearing having a seal gap to define a seal cavity. The seal cavity is filled with the bearing oil for lubricating the fluid dynamic bearing. The immiscible fluid is disposed on the bearing oil to prevent the bearing oil from evaporating from the seal cavity. In one embodiment, the immiscible fluid is insoluble in the bearing oil. |
