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： A thrust plate with grooved surfaces within a hydrodynamic bearing establishes pressure gradients which cause the lubricating fluid for the bearing to reliably remain within the region of the hydrodynamic bearing, with the pressure gradient imposed on the fluid causing the fluid to flow toward the center of the bearing rather than to be caused to be forced outward toward the far end of the bearing which could potentially result in a leakage of the fluid.

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： A metrology system for measuring a cone angle, a cone straightness, and a cone quality of a sample and method of using the metrology system are disclosed. The system includes a rotary stage, one or more workpiece fixtures that hold the samples in the rotary stage, and a number of different sized measurement devices. The measuring devices are positioned next to the rotary stage and measure the samples using contact. The rotary stage is free to rotate when the measuring devices are in a non-measuring state. The invention also includes a processor that collects data from the measurement devices and calculates the cone angle, the cone straightness, and the cone quality of each sample based on the data.

摘要： A 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.

摘要： A method and apparatus for a conical bearing is provided having a seal shield having an angle supported from the hub or sleeve which surrounds the shaft, and extending at an angle toward the outer surface of the shaft and spaced slightly away from the upper angular surface of the cone. As the cone and seal shield rotate relative to one another, fluid is drawn toward the lower inner region of the reservoir. However, due to shock or the like, some fluid may reach the radial gap between the end of the shield and the outer surface of the shaft, therefore, a ring is either incorporated into the upper end of the cone or pressed against the axial outer end of the cone, defining an axial gap which is smaller than the radial gap. In a preferred form of the invention, the ratio is about 1:3. When oil is introduced to either of the two gaps (typically by shock), it transfers or typically comes to rest in the axial gap, since the capillary attractive force increases as the gap size decreases; therefore, with the axial gap being smaller than the radial gap the oil will tend to transfer to the axial gap. As the seal is spun up as the shield and cone rotate relative to one another, centrifugal force acting on the oil in the axial gap transfers the oil radially away from the radial gap and into the reservoir defined between the shield and the cone. This transfer typically happens in two stages. First the oil in the radial gap is transferred into the axial gap, typically in the first few seconds of operation. The oil remaining in the axial gap then transfers into the reservoir volume due to centrifugal pumping.
