摘要： The present invention is a generally circular rotary seal that establishes sealing between relatively rotatable machine components for lubricant retention and environmental exclusion, and incorporates seal geometry that interacts with the lubricant during relative rotation to distribute a lubricant film within the dynamic sealing interface. The features of a variable inlet size, a variable dynamic lip flank slope, and a reduction in the magnitude and circumferentially oriented portion of the lubricant side interfacial contact pressure zone at the narrowest part of the lip, individually or in combination thereof, serve to maximize interfacial lubrication in severe operating conditions, and also serve to minimize lubricant shear area, seal torque, seal volume, and wear, while ensuring retrofitability into the seal grooves of existing equipment.

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.

摘要： The present invention is a generally circular rotary seal that establishes sealing between relatively rotatable machine components for lubricant retention and environmental exclusion, and incorporates seal geometry that interacts with the lubricant during relative rotation to distribute a lubricant film within the dynamic sealing interface. A preferably curved elevated contact pressure zone serves to maximize interfacial lubrication in critical areas during severe operating conditions by utilizing lubricant that would otherwise escape at the trailing edge of the hydrodynamic waves. The zones are produced by geometry that serves to minimize lubricant shear area, seal torque, seal volume, and wear, while ensuring retrofitability into the seal grooves of existing equipment.
