摘要： Two thrust bearing surfaces are separated by bearing fluid and are rotatable relative to one another. One of the bearing surfaces defines a plurality of continuous lands extending from an inner to an outer radius of the bearing surface. Adjacent lands define between them a continuous groove which has an undivided portion in an inner annulus and a divided portion in an outer annulus of the bearing surface. The continuous groove is divided in the divided portion by an intermediate land located between the adjacent continuous lands. The divided portion of the continuous groove communicates in unbroken fashion with the divided portion.

摘要： The present invention includes four sections or partitions: two thrust bearings which are formed by the sides of a grooved thrust plate and corresponding countersurfaces, the thrust bearings designed to cause fluid flow in a single direction up around the rotating thrust plate and upward along the surface of a rotating journal, and two journal bearings formed side-by-side on the journal formed between a rotating shaft and a bushing with multiple spiral-grooved sections being formed on the rotating shaft or in the stationary bushing. The two journal bearings are separated by a circumferential groove in the shaft which is connected by a radial bore to a hollow reservoir in the shaft for providing fluid to the journal bearing and the thrust bearing. By providing this bore and a second bore located near to the thrust bearing, the boundary conditions for the combined journal bearings and thrust bearings are fixed and a stable rotating shaft is achieved.

摘要： Hydrodynamic bearing having a shaft relatively rotatable with respect to a surrounding sleeve and having a thrust plate on one end thereof rotating in a recess of the sleeve. The shaft is preferably interrupted by a equi-pressure groove accessing a central reservoir in the shaft and having journal bearings defined by herringbone patterns above and below the groove to stabilize and provide stiffness to the cartridge. The stiffness of the cartridge is further enhanced by a thrust plate carried at one end of the shaft and rotating in a recess of the sleeve and being used to define thrust bearings on either surface thereof.

摘要： Thus, if a shock or other disturbance to a disc stack spindle bearing assembly occurs that tilts the bearing assembly, the resulting motion is both a tilting, and a motion which is axial. If a shock axially moves the hub assembly, only an axial motion occurs. Thus the system has a non-linear behavior. Pursuant to this invention, when a tilting disturbance occurs, and some of it is dissipated in a net axial movement at a different frequency, energy is subtracted out of the system with motion that is not linearly related to the disturbance was that created it.
摘要翻译：因此，如果发生对盘式主轴轴承组件的冲击或其它干扰，从而使轴承组件倾斜，则所产生的运动既是倾斜又是轴向的运动。如果冲击轴向移动轮毂组件，则仅发生轴向运动。因此，系统具有非线性行为。根据本发明，当发生倾斜干扰并且其中一些在不同频率的净轴向运动中消散时，能量被从系统中减去，其中与产生干扰的线性关系不是线性相关的运动。

摘要： A device comprises a recordable disc, a substrate adjacent to the recordable disc, and an actuation mechanism fixed to the substrate. The recordable disc includes a base layer and a recordable layer on the base layer. Additional electrodes or magnetic components may be placed on the base layer to provide electromagnetic or electrostatic forces to rotate the recordable disc when acted on by the actuation mechanism. As an example, the invention may utilize MEMS techniques in order to integrate a disc and motor of a disc drive as a common component.

摘要： Hybrid orbital fluid dynamic bearing motors are disclosed. The motors achieve improved efficiency advantages observed in fluid dynamic bearing motors containing an orbital ring. In addition, the hybrid orbital FDB motor has serial thrust bearings and traditional style journal bearings, which provide typically higher radial and angular stiffness not observed in previous orbital fluid dynamic bearing motor designs. Designs for centering orbital rings are also disclosed.

摘要： A bearing assembly having a shaft member having a bearing race and a piezoelectric member opposing the bearing race is situated so that when a voltage is applied to it, it expands against the bearing race so that a preload of the bearing is varied. The assembly includes a rotor having two outer bearing races opposing the shaft's inner bearing races. The contact angle for the upper bearing races is different than for the lower bearing races. In one embodiment of the present system, the piezoelectric member is disposed between the shaft member and the bearing race for varying the radial position of the bearing race. In another embodiment, the piezoelectric member is disposed for varying the axial position of the bearing race. In one embodiment, the system includes a hydrodynamic bearing assembly having a stator member having a hydrodynamic surface and a rotor member having a surface facing the stator member hydrodynamic surface. A piezoelectric member is attached to either the stator member or the rotor member for varying the width of said gap between said surfaces.

摘要： A method of creating an improved hydrodynamic fluid bearing is provided which is relatively insensitive to shock vibration changes in load and rotational speed. The hydrodynamic bearing motor in which the bearing is open at both the upper and lower ends, and in which the balance of fluid flow within the bearings is maintained. The assembly of the hydrodynamic bearing is more easily assembled, and the gaps are easily adjusted. In the design of the hydrodynamic bearing, the tolerances for assembly of the various components is minimized; that is, the critical nature of many of the gaps is diminished.
