摘要： A self-contained hydrodynamic bearing unit includes a shaft and a shaft housing defining an opening for receiving the shaft for relative rotation. The shaft and bearing define at least one radial hydrodynamic bearing and an annular thrust bearing, formed as a disk portion extending radially outward of a main cylindrical surface of the shaft which cooperates with an adjacent annular face of the shaft housing. A gap between an outer cylindrical wall of the thrust bearing disk portion and an adjacently facing cylindrical surface of the shaft housing provides a primary annular capillary seal segment. An annular bushing ring extends from the housing radially inwardly to enclose the thrust bearing disk, and cooperates with an adjacent outer face of the thrust bearing disk to provide a secondary containment capillary seal segment. Normally, lubricating liquid is in the bearing unit at the radial hydrodynamic bearing, at the hydrodynamic thrust bearing and in the primary annular capillary seal segment. However, if liquid overflows from, or extends beyond the primary seal segment as by thermal expansion, it is contained in the secondary seal segment and urged to return by centrifugal force to the primary seal segment. A tertiary containment seal may also be provided to prevent escape of liquid to the external ambient.

摘要： Particle traps in a hydrodynamic bearing unit prevent particles, generated by repeated motor start and stop operations or lubricant cavitation caused by shock loads or introduced by ambient sources, from circulating with the bearing lubricant, thereby preventing accelerated wear of bearing grooves. Each trap is defined by an annular bevel shaped channel defined along the inner radial wall of a shaft sleeve. Each trap is located in close proximity to hydrodynamic bearings so that existing particles and any wear particles generated by the bearings may be pumped into the traps by centrifugal force created by rotation of the bearing unit and imparted to the lubricant. The centrifuge-like effect forces the particles against the back wall of each channel while the bevel shaped configuration of the channels prevents particles from migrating out of the channels after the motor stops. The configuration and location of the traps eliminate the need for global recirculation of bearing lubricant, thereby reducing the risk of leakage.

摘要： A self-contained hydrodynamic bearing unit with improved sealing and performance is disclosed. Centrifugal capillary seals are angularly defined between an outwardly tapered outer surface of a top screw and an inwardly tapered inner surface of an annular clamp ring at the top of the bearing unit as well as between an outwardly tapered outer surface of a seal plate and an inwardly tapered inner surface of an annular clamp ring at the bottom of the bearing unit. During operation, bearing lubricant is pumped away from the seal opening and toward the bearings by centrifugal force at the seals, providing dynamic sealing. When the bearing unit is not rotating, capillary forces retain the lubricant within the seal, preventing the lubricant from leaking. The tapered configuration of the seals also shortens the vertical seal length for a given effective seal length, thereby maximizing the journal bearing length/span and improving dynamic performance of the bearing unit.
