Definitions

  • This invention is concerned with the use of annular, lipped seals around a rotating or reciprocating shaft that penetrates a machine case or body. Such seals serve to close the annular gap between the stationary case or body part and the rotating or reciprocating shaft.
  • lipped oil seals are typically used around rotating shafts in internal combustion engines and are often used to prevent the leakage of the process fluid, such as water or a water-based mixture, along the shaft operating a pump.
  • This invention relates to the installation and selective deployment of lip seal members about an annular moving part, t such as a rotating or reciprocating shaft.
  • the radially extending outer plate of the tool is particularly adapted to engage with the end plate or housing body of the machine to act as a centering guide upon axial insertion of the retracted lip seal into the gap between the shaft and the stationary casing or body of the machine.
  • the seal is assembled into the gap by interference fit with the inner diameter of the machine's shaft housing.
  • lip seals In operation, lip seals have a limited useful life due to wear. At the end of the useful life, leakage will develop at the interface between the stationary lip seal and the reciprocating/rotating shaft. When leakage is observed, the operation of the fluid handling machine generally must be terminated and the machine at least partially dismantled to remove the previous lip seal for purposes of replacement. There is the possibility that a significant cost in operating downtime may be suffered due to the replacement of the lip seal.
  • U.S. Patent 2,836,441 to Doble discloses a shaft seal system in which the shaft includes a conical surface and the seal is axially repositionable along the shaft to improve engagement between the seal and the shaft as the seal experiences wear.
  • U.S. Patent 3,773,336 to Walter discloses a seal system in which a spare seal member is initially positioned adjacent a recess in the shaft (or associated bushing), thereby avoiding engagement with the shaft until needed. The spare seal member may be brought into contact with the shaft by axially repositioning the seal holder or the shaft/bushing.
  • Patents 5,820,132 and 6,152,454 to Marnot also describe seal systems in which a spare seal is initially positioned adjacent a set back region formed in the shaft. As the spare seal is axially repositioned so as to be brought into engagement with the shaft, the replaced seal is moved adjacent a set back region formed in the shaft, i.e., out of engagement with the shaft.
  • the inventor has devised a more economical sleeve-type system for the simplified, yet reliable, installation of a lip seal or seals into tlji'e 'gap about a shaft to enable the shaft to be sealed during operation of the machine. Additionally, the inventor has devised a back-up or spare seal capability to extend useful wear life of the sealing operation. Summary Of The Invention
  • a seal cartridge in the form of a ring containing an annular lipped seal or lip seal.
  • the seal ring is formed with an inboard, radial front wall connected to an axially extending containment wall, which serves as the outer diameter wall surrounding the lip seal carried by the ring, and ending with an outboard radially extending backplate.
  • the backplate extends radially inward in parallel with the annular extent of the lip seal to a point short of the radial extent to which the lip portion of the seal will extend into contact with the shaft.
  • a generally L-shaped sleeve having an axially extending) cylindrical surface and an upstanding, radially extending outer wall, is applied up against the backplate of the seal ring such that its axially extending cylindrical surface retracts (or raises) the lip portion of the seal into an at rest, non-deployed position.
  • the radial extent of the outer wall of this sleeve is less than the diameter of the seal ring, and thus will not engage with the end plate,or housing body of the machine.
  • the seal ring is installed into the gap about the shaft, the sleeve serving to center the seal ring in the gap and prevent the lip from becoming damaged or deformed during installation.
  • the seal ring becomes fitted about the shaft in the shaft housing of the machine by an interference fit of the seal ring containment wall with the inner diameter surface of the shaft housing.
  • the sleeve is self-centered and self-supported upon thejseal ring by virtue of a cantilever effect, making use of the L-shape of the sleeve.
  • the flex of the lip end of the seal against the axially extending cylindrical surface portion of the sleeve biases the front-facing surface of the sleeve outer wall against the backplate to which it is pressed, and together these forces on the sleeve hold the L-shaped sleeve in place, concentric about the shaft.
  • a register step may be formed at the back end of the cylindrical surface of the sleeve to align the sleeve onto the seal ring by having the step engage with the inner diameter of the backplate of the seal ring.
  • a seal cartridge in the form of a ring containing at least two back-to-back annular lipped seals or lip seals.
  • the seal ring is formed with an inboard, radial front wall connected to an axially extending containment wall, which serves as the outer diameter wall surrounding the series of lip seals carried by the ring, and ending with an outboard radially extending back wall.
  • the back wall extends radially inward in parallel with the annular extent of the lip seals to a point short of the radial extent to which the lip portions of the seal will extend into contact with the shaft.
  • a first, generally L-shaped sleeve having an axially extending cylindrical surface and an upstanding, radially extending outer wall, is applied up against the back wall of the seal ring such that its axially extending cylindrical surface retracts (or raises) the lip portion of the outboard seal or seals into an at rest, non-deployed position.
  • the radial extent of the outer wall of this first sleeve is less than the diameter of the seal ring, and thus will not engage with the end plate or housing body of the machine.
  • a second, generally L-shaped sleeve also having an axially extending cylindrical surface, elongated relative to the cylindrical surface of the first sleeve, and a radially extending back wall, is fitted up against the back of ths first sleeve so as to place the lip end of the inboard seal in a similarly raised or retracted position.
  • the seal ring With both the first and second sleeves applied to the seal cartridge, the seal ring is installed into the gap about the shaft, the sleeves serving to center the seal ring in the gap and prevent the lips from becoming damaged or deformed during installation.
  • the seal ring becomes fitted about the shaft in the shaft housing of the machine by an interference fit of the seal ring containment wall with the inner diameter surface of the shaft housing.
  • the second, innermost sleeve is removed, such that the inboard lip seal is deployed against the surface of the shaft, and this second sleeve may then be discarded.
  • the first sleeve is retained with the thus installed seal ring until such time as the inboard seal wears to the point of a detectable leakage.
  • the first sleeve is retracted to thus deploy, as a back-up, the next outboard or remaining outboard lip seal.
  • the w ( sar life of the thus deployed, next or remaining outboard seal will be longer than the preceding seals wear life because each preceding seal will, even though worn, nonetheless provide some level of damming against leakage and thus reduce pressure against the next adjacent outboard seal.
  • the last outboard seal has been deployed, the first sleeve will become removed from the seal ring and may be discarded.
  • the sleeves are self-centered and self-supported upon the seal ring by virtue of a cantilever effect, making use of the L-shape of the sleeve.
  • the first sleeve is fitted with an outboard seal lip to exclude atmospheric contaminants and the second sleeve also serves to hold the excluder seal in a retracted position unti) after the seal cartridge has been installed about the shaft and the second sleeve is removed.
  • a register step may be formed at the back end of the cylindrical surface of the first sleeve to align the first sleeve onto the seal ring by having the step engage with the inner diameter of the back wall of the seal ring.

Abstract

Cette invention concerne un cartouche d'étanchéité (120) comprenant au moins deux joints à lèvre placés dos-à-dos. Un premier manchon généralement de forme en L (110) est appliqué contre la paroi postérieure de la bague d'étanchéité (121) de telle sorte que la surface cylindrique déployée axialement (111) rappelle la partie lèvre du joint extérieur en position non déployée. Une second manchon généralement de forme en L (140) est monté contre le dos du premier manchon de manière à ce que l'extrémité lèvre du joint intérieur se trouve dans une position relevée ou de rappel. Au moment de monter la bague d'étanchéité sur l'arbre et dans le logement de l'arbre, on retire le second manchon qui se trouve le plus à l'intérieur de telle sorte que le joint à lèvre intérieur se déploie contre la surface de l'arbre (130). Lorsqu'une fuite est détectée au niveau du joint intérieur, le premier manchon est rappelé, ce qui fait se déployer le joint à lèvre extérieur restant (122).
