Abstract: A system and method are described for ballizing and measuring a workpiece bore hole. In one embodiment, a ballizing unit having a distal end removably coupled to a ballizing member moves the ballizing member from a first position within the bore hole to a second position. A metrology unit having a distal end removably coupled to the ballizing member moves the ballizing member from the second position back to the first position. A sensor detects a force exerted on the ballizing member by the workpiece at a third position, which is located between the first and second positions.

Abstract: A hydrodynamic fluid bearing useful in a bearing cartridge which cartridge may be incorporated into a spindle motor or the like, where the bearing includes a shaft, a conical bearing supported on the shaft, and journal bearings located at least on one side and typically both above and below the conical bearing. A sleeve is mounted for rotation relative to the shaft and defines, in cooperation with the shaft, the gaps necessary for both the conical hydrodynamic bearing and the axial, journal bearings. At an end of the shaft, capillary seals are defined between the sleeve and the shaft so that fluid does not escape from the hydrodynamic bearing. The shaft itself includes a central hole, with bores communicating with both the conical bearing and the journal bearings to maintain appropriate pressure balances.In a further desirable feature, in some embodiments the diameter of one end of the shaft can be made greater than the diameter of the other end of the shaft.

Abstract: A spindle motor in a disc drive has a rotor assembly rotatably mounted to a base. A stator is mounted to the base and a magnet is mounted to the rotor assembly. The magnet or the stator is allowed to move in an axial direction relative to the other under the influence of magnetic interaction between the magnet and the stator. The magnet and stator are then rigidly fixed relative to one another in the axial direction.

Abstract: The third dynamic bearing includes a fixed shaft and a sleeve rotating around and surrounding the shaft, and at least first and second thrust plates separated by a portion of the shaft. The shaft includes an axial hole to vent appropriate positions inside the bearing. The axial hole extends from one end of the shaft past at least one of the thrust plates. The axial hole is connected by a radial bore to the bearing gap at a location between the thrust plate closest to that one end of the shaft and the facing counterplate.Alternatively, the axial hole can extend beyond the farthest thrust plate from the one end of the shaft, and can be connected to the bearing gap by a second radial cross-bore. A meniscus forms in the bearing gap on either side of each vent opening, decoupling adjacent bearing sections of the hydrodynamic bearing.

The hydrodynamic bearing can also be used as a bearing cartridge or as the cartridge that may be incorporated into a spindle motor or the like, where the bearing includes a shaft and at least two independent bearings each comprising a thrust plate supported on the shaft and a counter plate incorporated in a sleeve which is capable of relative rotation around the shaft.

Abstract: The hydrodynamic bearing gap from one end to the other of the shaft and sleeve combination is effectively separated into sections, with the fluid in each bearing section being contained within that section. The viscosity of the fluid in each bearing section can then be selected to optimize the characteristics of the entire hydrodynamic bearing. Typically, the sections of the bearing adjacent each open end of the bearing would be filled with a fluid with relatively high viscosity. The remaining sections, toward the center of bearing, would typically be filled with a lower viscosity fluid, liquid or gas so that the power consumption within the motor itself would be minimized.
