摘要： A hydrodynamic bearing useful as a bearing cartridge or as the cartridge may be incorporated into a spindle motor or the like, where the bearing includes a stationary shaft and two independent bearings, comprising a top cone and a bottom cone separated by a segment of the shaft. The bearing includes a sleeve rotating around and surrounding the shaft, and the top cone and bottom cone and defining a narrow gap between the sleeve and the shaft and cones. Sealing plates are supported on the sleeve to seal off the ends of the bearing and are located along the shaft beyond the cones. A gap also exists between an interior surface portion of each cone and the shaft. Thus, separate flow paths are established, one around the top cone and one around the bottom cone. By providing two independent paths, the flow rates do not have to be the same in each conical flow path for the bearing seals to function properly.
摘要翻译：可用作轴承筒或筒的流体动力轴承可以结合到主轴电机等中，其中轴承包括固定轴和两个独立的轴承，包括顶部锥体和由轴的一部分分开的底部锥体。轴承包括围绕轴围绕并且围绕轴的套筒，以及顶部锥形和底部锥形件，并且在套筒和轴和锥体之间限定狭窄的间隙。密封板支撑在套筒上以密封轴承的端部并且沿着轴位于锥体以外。在每个锥体的内表面部分和轴之间也存在间隙。因此，建立单独的流动路径，一个围绕顶部锥体，一个围绕底部锥体。通过提供两个独立的路径，每个锥形流动路径中的流速不必相同，用于轴承密封件正常工作。

摘要： A shaft having a thrust plate at or near one end, and a sleeve cooperating with the shaft to define one or more journal bearings and a counterplate (which may be supported by the sleeve or defined by the sleeve) defining at least one counter thrust surface in cooperation with the thrust plate. In order to maintain an enhanced fluid distribution across the journal bearing and maintain pressure distribution boundary conditions as desired, one or more grooves are defined along the shaft extending behind or between the thrust plate and the shaft. The grooves typically extend from one radial side of the thrustplate behind the thrustplate and up to a point on the shaft adjacent or nearly adjacent to one of the journal bearings. Alternatively, the slot or slots may extend to a point between two journal bearings. In this way, the pressure from the distal axial surface of the thrust bearing to the point where the slot terminates is equalized, enhancing the stability of the boundary conditions over each of the journal bearings and equalizing the pressure at the opposite ends of the fluid distribution slot.
摘要翻译：具有在一端处或靠近一端的止推板的轴和与该轴配合以限定一个或多个轴颈轴承的套筒和一个对准板（其可由套筒支撑或由套筒限定）限定至少一个反推力表面与推力板配合使用。为了在轴颈轴承上保持增强的流体分布并且根据需要保持压力分布边界条件，沿着延伸在推力板和轴之后或之间的轴限定一个或多个凹槽。凹槽通常从止推板后面的推力板的一个径向侧延伸到轴上的与轴颈轴承之一相邻或接近相邻的点。或者，槽或槽可以延伸到两个轴颈轴承之间的点。以这种方式，从止推轴承的远侧轴向表面到槽终止点的压力相等，增强了每个轴颈轴承上的边界条件的稳定性，并均衡流体分布相对端的压力槽
