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 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.

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 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，当发生倾斜扰动并且其中一些在不同频率的净轴向运动中消散时，能量与系统中的运动无关，该运动与产生它的扰动不成线性关系。
