    摘要： A shaft seal reduces leakage between a rotating shaft such as a rotor and a stator. The shaft seal or shingle seal includes a plurality of compliant-plate members attached to the stator in facing relation. The compliant-plate members define a sealing ring between the stator and the rotating shaft. Each of the compliant-plate members includes a plurality of shingles, where adjacent compliant-plate members are disposed relative to each other such that the shingles are at least partially staggered in a direction of axial leakage.

    摘要： A shaft seal serves to reduce leakage between a rotating shaft and a static shell. The shaft seal includes a plurality of compliant plate members, each having a root and a tip. The compliant plate members are secured to the static shell at their root in facing relation. The tips of the compliant plate members define a sealing ring between the static shell and the rotating shaft. An axial flow resistance member is disposed within the compliant plate members and serves as a barrier to axial leakage flow between the compliant plate members.

    摘要： A shaft seal reduces leakage between a rotating shaft and a stator. The shaft seal includes a plurality of plate members attached to the stator in facing relation. The plate members define a sealing ring between the stator shell and the rotating shaft. A thickness of the plate members tapers from thick to thin from a stator end to a rotating shaft end. In this manner, with the more tightly packed tips of the plate members, axial leakage is reduced by tapering the plate members so that the plate roots are thicker than the plate tips.

    摘要： A method and seal assembly for a rotary machine including a rotary component and a stationary component is provided. The method includes providing a seal housing including a front plate and a back plate that is spaced from the front plate such that a cavity is defined between the front plate and the back plate. The method also includes coupling a plurality of flexible compliant plates to at least one of the seal housing and the stationary component such that the compliant plates are spaced from the front plate and the back plate within the cavity, and coupling at least one projection to at least one of the seal housing and the compliant plates such that the at least one projection facilitates reducing flow through at least one of a first axial gap and a second axial gap that are defined between the seal housing and the compliant plates.

    摘要： Flexure bearing systems and configurations guide translational motion along a single-axis in micro and macro applications such as micro-electro-mechanical system (MEMS) devices including sensors and actuators like electrostatic comb-drive actuators. The flexure bearing systems and configurations described herein provide an improved constraint against movement (i.e., stiffness) of the primary mover in non-motion axes such as a bearing axis.
