摘要： A split mechanical composite seal assembly for providing a seal between a rotating shaft and a static surface. The split mechanical composite seal assembly includes first and second axially adjacent annular seal elements. The first and second seal elements each include a sealing edge contacting the shaft to provide a respective seal between the first and second seal element and the shaft. A static housing receives the first and second seal elements and engages the static surface to provide a static stationary seal, while concomitantly providing a flex region that engages the seal elements to form a dynamic seal therewith. A holder assembly receives one seal element and may include a double-angled lead-in to facilitate installation of the seal element. The holder assembly may include a detent groove for receiving and retaining an O-ring disposed about the seal element. The static housing may comprise two mating segments having overlapping surfaces.

摘要： A split seal component includes two seal face segments in two holder halves and a method of assembly and installation. Each seal face segment has a primary sealing surface and a section extending axially from each primary sealing surface. The holder halves are adapted to be joined together to rigidly hold the circular seal face. The holder being constructed and arranged to mount to a shaft. In a unitized design (FIGS. 29/30) a rotary assembly of seal face segment (206) and rotary holder half (102) may have a contact surface (712) to contact abutment surface (714) of a stationary holder half (370) of a stationary assembly. A biasing device (e.g., spring 514) pushes stationary seal face segment (406) against rotary seal face segment (206) thereby to push contact surface (712) into contact with abutment surface (714). After the stationary assembly is fixed in place around a shaft, the contact and abutment surfaces (712, 714) may be axially displaced (FIG. 30) to provide operational clearance and the rotary assembly then attached around the shaft. Contact between the surfaces (712, 714) can thus provide pre-installation retention of a rotary holder half by a stationary holder half for unitized assembly, prior to axial displacement as assembly is completed.

摘要： A system and method of manufacturing improved wear ring assemblies and positive pressure shaft seals. The wear ring assemblies are made from stacked layers of flat metal. Different shaped component parts of the wear ring assemblies are cut from various sheets of metal. The component parts are stacked to form different sections of the wear ring assemblies. The stacked component parts are welded or otherwise bound together. The resulting sections of the wear ring assemblies are then assembled to form the annular structure of a full wear ring assembly. The result is a wear ring assembly that is both easy and inexpensive to produce.

摘要： A mechanical seal for providing fluid sealing between a housing and a rotatable shaft includes a first seal ring having a first seal face and a second seal ring having a second seal face. The first seal face further has a first portion and a second portion and the seal faces of the first and second seal rings are opposed to each other when assembled. The first seal ring or the second seal ring is adapted to rotate with the rotatable shaft, and the other seal ring is restrained from rotating. The seal faces are configured to produce a primarily hydrostatic fluid force between at least a portion of the first portion of the first seal face and at least a portion of the second seal face. In addition, the seal faces are configured to produce a hydrodynamic fluid force and a hydrostatic fluid force between at least a portion of the second portion of the first seal face and at least a portion of the second seal face.

摘要： An improved mechanical seal of the type useful to form a seal between a stationary housing and a rotatable shaft having a shaft axis extending through an opening in the housing. The mechanical seal has stationary components and rotatable components. The stationary components comprise a stationary seal element having a stationary seal surface and the rotatable components comprise a rotatable seal element having a rotatable seal surface. The stationary and rotatable seal surfaces have substantially equal and oblique, preferably, acute, angles to the shaft axis. The seal surfaces oppose each other and are forced together to form a seal. The seal can be secured in place by improved connector clips.

摘要： A split mechanical seal, for mounting to a stationary housing that contains a rotating shaft, including first and second seal ring assemblies, at least one resilient biasing element and at least one axial biasing element. The first and second seal ring assemblies each include a seal ring having two segments that are resiliently supported in the seal. The segments have an outer surface and a pair of segment sealing faces disposed at opposite ends of the segments. The resilient biasing element is concentrically disposed about and in intimate contact with the outer surface of one of the seal rings, for applying a first radially inward force that biases the sealing faces of the seal ring segments into sealing contact with each other. The mechanical seal includes a pair of resilient biasing elements disposed about each seal ring, and the resilient biasing element is preferably an elastomeric member. The axial biasing element is associated with at least one seal ring for generating and applying, in cooperation with the elastomeric member, a second radially inward force; the second force operating to bias the segment sealing faces together when the mechanical seal is exposed to a selected pressure condition. The axial biasing element is an abutment, integrally formed with the segments of both seal rings, that has a radially outwardly slanted outer surface. The abutment transforms the axial force into an axial force component and a second radially inward force component. This second radially inward component also operates to bias the sealing faces of the seal ring segments into sealing contact with each other. The seal further includes integrally formed screw housings that have formed therethrough a fastener-receiving aperture. The aperture has a tapped smaller-diameter portion and an untapped larger diameter portion. The aperture mounts a screw that has a screw-head and a shaft. The shaft has a tapped larger-diameter distal end and a smaller-diameter proximal end. The screw when mounted within the aperture, is positively maintained therein.

摘要： A sealing assembly for effecting a rotary seal between a stationary housing (5) and a rotary drum (1) by a number of arcuate sealing segments (8) engaging a radial sealing surface (6) on the housing (5) and a non-radial sealing surface (3) on the rotary drum (1), the segments being urge into sealing engagement with the sealing surfaces by a constantly acting radial force. The non-radial surface (3) tapers conically towards the radial surface (6). With this arrangement, the radially acting force, such as produced by a cable (15), urging the segments (8) radially inwards, also provide the requisite force for urging the segments towards the radial sealing surface (6), as the reaction force on the non-radial or conical surface (3) has a component directed towards the radial sealing surface (6).
