摘要： A radial shaft seal includes a powder coating on a shaft and a sealing lip that lands on the powder coating. The powder coating is formed of a thermosetting resin and a filler material. The filler material has a melting point above the cure temperature of the thermosetting resin. The powder coating may be porous. The powder coating may be made up of dry powder particles adhered to one-another with spaces in between. The filler may be present in an amount between 15% and 35% within the individual particles. The powder coating is adapted to wear away at locations of maximum interference with the sealing lip while continuing to provide a durable seal. This wear behavior compensates for shaft wobble.

摘要： A roller bearing for a wind turbine includes a first inner ring with an axial protrusion, a second inner ring, an outer ring arranged coaxially over the first inner ring and the second inner ring, and first and second pluralities of rolling elements. The rolling elements roll on respective inner ring and outer ring raceways. The roller bearing also has a bearing interior at least partially filled with a lubricant, an additional ring arranged radially outwardly on the axial protrusion, an axial extension connected to the outer ring and includes a cylindrical inner sealing face, and a radial shaft sealing ring installed on the additional ring in a radially outward manner. The radial shaft sealing ring has a radially outwardly directed sealing lip in radial contact with the cylindrical inner sealing face.

摘要： A control valve configured to set a process fluid stream of a processing plant can include a valve housing, a valve component, an annular-groove-shaped seal reception, and a seal. The valve housing can include an inlet, an outlet and an aperture extending between the inlet and the outlet along a longitudinal axis. The valve component can be mounted on the valve housing and can be a valve seat and/or a valve cage. The annular-groove-shaped seal reception can be confined by the valve component and the valve housing. The seal can be fit into the seal reception. The valve component and the valve housing can each form a respective ledge protruding in a radial direction to define the annular-groove-shaped seal reception. The ledges can each be configured to confine the seal reception in a respective axial direction.

摘要： A sealing device for sealing between a valve body which is movably disposed in a valve box and which controls the flow of a fluid, and a tube which is connected to the valve box or is a part of the valve box and through which the fluid flows, is provided. The sealing device includes: a first seal portion which is a resin annular plate or film and is to be closely contacted with the outer surface of the valve body; and a cylindrical second seal portion which is formed from a material more flexible than that of the first seal portion, contacts the inner outer surface of the tube, and prevents the fluid from leaking from the tube. The first seal portion and the second seal portion are integrally joined. A flange joined to the first seal portion is formed on an edge of the second seal portion.

摘要： A seal assembly includes a first and second machine element, a seal and a support ring. The support ring has a first side edge facing a high-pressure side which is partially convexly curved, formed obliquely or is partially formed at an acute angle relative to a movement axis of the two machine elements. The seal has a retaining portion and a primary sealing lip extending from the retaining portion on the high-pressure side and abuts in a dynamically sealing manner against a sealing surface of the second machine element. The primary sealing lip directly abuts and is supported over the majority of its longitudinal extent on the first side edge of the support ring on the low-pressure side. The retaining section of the seal is held clamped between the support ring and the first machine element and abuts the first machine element in a statically or indirectly statically sealing manner.

摘要： Spring energized seal assemblies configured for use in static or dynamic application and methods of using and making same are provided. The seal assemblies can each have a sealing component and optionally a backup ring or a locking ring or both. An annular spring can be used with a spring groove of either the backup ring or the locking to facilitate assembling of the mentioned components of a seal assembly onto each other and the entire seal assembly into a seal cavity of a housing.

摘要： A sealing apparatus includes an annular lip member made of a resin material, and an annular spring member made of a metal material. The lip member includes a lip base portion, an outer-periphery-side lip, and an inner-periphery-side lip. The spring member includes: a spring base portion having an annular shape about an axis; an outer periphery pressing portion for pressing the outer-periphery-side lip; and an inner periphery pressing portion for pressing the inner-periphery-side lip. The spring member is accommodated in an accommodating groove. The outer periphery pressing portion includes a plurality of outer periphery pressing pieces, and the inner periphery pressing portion includes a plurality of inner periphery pressing pieces. The outer periphery pressing piece has a cutout extending along the axis without reaching a high-pressure-side edge of the outer periphery pressing piece, and the inner periphery pressing piece has a cutout extending along the axis without reaching a high-pressure-side edge of the inner periphery pressing piece.

摘要： A valve stem packing assembly can seal a valve stem to a valve body having a body cavity. The packing assembly includes a packing ring circumscribing the valve stem within a stem opening extending axially through the valve body. A primary dynamic seal is positioned to seal a dynamic leak path between the packing ring and the valve stem. A secondary dynamic seal is spaced axially apart and functionally independent from the primary dynamic seal and positioned to redundantly seal the dynamic leak path. A primary static seal is positioned to seal a static leak path between the packing ring and the valve body. A secondary static seal is spaced axially apart and functionally independent from the primary static seal and positioned to redundantly seal the static leak path.

摘要： A seal assembly is disclosed for providing a seal against a body. The assembly includes an elastically-deformable sealing member with a sealing surface facing a surface of the body. The assembly also includes a shape memory alloy biasing member. The biasing member is configured to bias the sealing surface to different positions with respect to the surface of the body or with different pressures against the surface of the body in response to a displacement response of the shape memory alloy to thermal stimulus. The body can be dynamic relative to the sealing member such as a rotatable shaft, static relative to the sealing member such as a case or housing, or can be either static or dynamic in response to the SMA displacement such as a snubber assembly.
