摘要： A hydrodynamically lubricating seal has a generally circular seal body defining a static sealing surface and having a dynamic sealing lip projecting from the seal body for establishing sealing relation with a relatively rotatable surface. When compressed against a relatively rotatable surface, dynamic sealing lip defines a hydrodynamic geometry which wedges a film of lubricating fluid into the interface between the seal and the relatively rotatable surface in response to relative rotation. The dynamic sealing lip geometry maintains interfacial contact pressure within the dynamic sealing interface for efficient hydrodynamic lubrication and environmental exclusion, which enhances lubrication and environmental exclusion while permitting relatively high initial compression and relatively low torque. In abrasive environments, the improved exclusionary action results in a dramatic reduction of seal and shaft wear, compared to prior art, and provides a significant increase in seal life. The invention also increases seal life by making higher levels of initial compression possible, compared to prior art, without compromising hydrodynamic lubrication. This added compression makes the seal more tolerant of compression set, abrasive wear, mechanical misalignment, dynamic runout and manufacturing tolerances.
摘要翻译：流体动力学润滑密封件具有限定静态密封表面的大致圆形的密封体，并且具有从密封体突出的动态密封唇，用于与相对可旋转的表面建立密封关系。当相对于相对旋转的表面压缩时，动态密封唇限定了响应于相对旋转将润滑流体膜楔入密封件和相对可旋转表面之间的界面的流体动力学几何形状。动态密封唇几何形状保持动态密封界面内的界面接触压力，以实现有效的流体动力学润滑和环境排除，从而增强润滑和环境排除，同时允许相对较高的初始压缩和相对较低的扭矩。在磨蚀性环境中，改进的排除动作导致与现有技术相比，密封和轴的磨损大大降低，并且密封寿命显着增加。本发明通过与现有技术相比可以实现更高水平的初始压缩而不损害流体动力学润滑来提高密封寿命。这种增加的压缩使得密封件更容忍压缩永久变形，磨损磨损，机械失准，动态跳动和制造公差。

摘要： A hydrodynamically lubricating rotary seal for partitioning a lubricant from an environment has a generally circular seal body, a sloping dynamic sealing lip, and an energizer. The dynamic sealing lip is provided for establishing compressed sealing relation with a relatively rotatable surface, and has a sloping dynamic sealing surface that varies in width, and also has a hydrodynamic inlet curvature that varies in position around the circumference of the seal. When the seal is installed against a relatively rotatable surface, the dynamic sealing lip deforms to define a variable width interfacial contact footprint against the relatively rotatable surface that is wavy on the lubricant side, and wedges a film of lubricating fluid into the interface in response to relative rotation. The environment edge of the interfacial contact footprint is substantially circular, and therefore does not produce a hydrodynamic wedging action in response to relative rotation.

摘要： A novel hydrodynamically lubricated compression type rotary seal that is suitable for lubricant retention and environmental exclusion. Particularly, the seal geometry ensures constraint of a hydrodynamic seal in a manner preventing skew-induced wear and provides adequate room within the seal gland to accommodate thermal expansion. The seal accommodates large as-manufactured variations in the coefficient of thermal expansion of the sealing material, provides a relatively stiff integral spring effect to minimize pressure-induced shuttling of the seal within the gland, and also maintains interfacial contact pressure within the dynamic sealing interface in an optimum range for efficient hydrodynamic lubrication and environment exclusion. The seal geometry also provides for complete support about the circumference of the seal to receive environmental pressure, as compared the interrupted character of seal support set forth in U.S. Pat. Nos. 5,873,576 and 6,036,192 and provides a hydrodynamic seal which is suitable for use with non-Newtonian lubricants.

摘要： A hydrodynamically lubricated squeeze packing type rotary shaft with a cross-sectional geometry suitable for pressurized lubricant retention is provided which, in the preferred embodiment, incorporates a protuberant static sealing interface that, compared to prior art, dramatically improves the exclusionary action of the dynamic sealing interface in low pressure and unpressurized applications by achieving symmetrical deformation of the seal at the static and dynamic sealing interfaces. In abrasive environments, the improved exclusionary action results in a dramatic reduction of seal and shaft wear, compared to prior art, and provides a significant increase in seal life.The invention also increases seal life by making higher levels of initial compression possible, compared to prior art, without compromising hydrodynamic lubrication; this added compression makes the seal more tolerant of compression set, abrasive wear, mechanical misalignment, dynamic runout, and manufacturing tolerances, and also makes hydrodynamic seals with smaller cross-sections more practical.In alternate embodiments, the benefits enumerated above are achieved by cooperative configurations of the seal and the gland which achieve symmetrical deformation of the seal at the static and dynamic sealing interfaces. The seal may also be configured such that predetermined radial compression deforms it to a desired operative configuration, even through symmetrical deformation is lacking.

At least one annular laterally translatable seal carrier is provided. First and second annular resilient sealing elements are supported in axially spaced relation by the annular seal carriers and have sealing relation with the rotary shaft. The seal housing and at least one seal carrier define a first pressure staging chamber exposed to the first annular resilient sealing element and a second pressure staging chamber located between and exposed to the first and second annular resilient sealing elements. A first fluid is circulated to the first pressure chamber at a pressure P1, and a second staging pressure fluid is circulated to the second pressure chamber at a fraction of pressure P1 to achieve pressure staging, cooling of the seals. Seal placement provides hydraulic force balancing of the annular seal carriers.

摘要： A hydrodynamically lubricated sealing element for applications where the pressure of a contained fluid can be significantly greater than the pressure of the seal lubricant. The sealing element retains the pressure of the contained fluid and provides hydrodynamic lubricant pumping activity at the dynamic sealing interface to enhance service life. The invention is particularly suitable for oilfield drilling swivel washpipe assemblies, downhole drilling tools, and rotary mining equipment, and for applications such as artificial lift pump stuffing box assemblies and centrifugal pumps where a rotating shaft penetrates a pressurized reservoir that is filled with abrasive-laden liquids, mixtures, or slurries.

摘要： A seal backup ring is provided with undulating surfaces which create circumferential convergence with a relatively rotatable surface. The backup ring is configured so that differential pressure acting across a rotary seal forces portions of the backup ring against the relatively rotatable surface, closing, or substantially closing, the extrusion gap that the rotary seal is exposed to. In response to relative rotation between the backup ring and the mating relatively rotatable surface, the circumferential convergence promotes hydrodynamic lubrication within the dynamic interface that exists between the backup ring and the relatively rotatable surface. The modulus of elasticity of the backup ring is greater than the modulus of elasticity of the rotary seal.
