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 compliant seal assembly for a rotating machine is provided. The seal assembly includes a static member, a movable member and a biasing member. The static member is rigidly fixed to the machine at its fore and aft ends. The movable portion has a first sealing surface configured to seal against a rotating member and a rear surface, which may be exposed to a fluid pressure to urge the first sealing surface toward a sealing position with the rotating member. The static and the movable members further include sealing surfaces at their fore, aft and end faces to seal against leakage of gas between the static and the movable members. The biasing member is configured to support the movable member on the static member and to urge the movable member away from the sealing position so as to reduce force on the rotating member during contact of the rotating member with the first sealing surface of the movable member.

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.

摘要: An actuation pressure control system effects actuation of adjustable seal segments between stationary and rotating turbomachinery members. At least one actuator is coupled with each of the adjustable seal segments and controls a position of the seal segments, respectively. A pressure system is disposed within the turbomachinery that measures or estimates ambient pressure representing an actuator back pressure acting against the actuator. A pressure regulator via a controller pressurizes the actuator to a level sufficient for a desired seal operation and controls actuator pressure based on the actuator back pressure.

摘要: A minimal access tool includes a frame arranged to be attached to an arm of a user, a tool shaft having a proximal end and a distal end, where the tool shaft proximal end is connected to the frame. The tool further includes an input joint having a first end connected to the frame and a second end arranged to receive user input, the input joint including a virtual center-of-rotation (VC) mechanism which provides a center of rotation that generally coincides with a wrist joint of the user. An output joint is connected to the tool shaft distal end, where the output joint is coupled to the input joint via a mechanical transmission connected therebetween to correlate motion of the input joint to motion of the output joint.

摘要: A multiple degrees of freedom motion system comprising an arrangement of rigid stages, flexure constraint modules, actuators, and sensors. These components of the motion system are arranged and connected in a systematic fashion to provide a high degree of decoupling between the motion axes, suitable placement of ground-mounted actuators to actuate each motion axis, and suitable placement of sensors to allow end-point measurement along each motion axis. This arrangement of rigid stages, flexure constraint modules, actuators and sensors enables large motion range and high motion quality in the motion system, while using standard and commonly available components.
