摘要： A hydrodynamically lubricating rotary seal for partitioning a lubricant from an environment has a generally circular seal body and sloping, generally opposed projecting static and dynamic sealing lips. 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： In a known rotary shaft seal with two sealing lips, a first diaphragm body (20) with a first sealing lip (21) is mounted on a support element (22) and inserted in a second diaphragm body (23) with a second sealing lip (27) that rests against a pressure mount (24) and is mounted in the bearing mount (1). The object of the invention is to prevent the pressure medium from passing through the gap (26) between the two diaphragm bodies, which is open towards the pressure side, and ensure that the first diaphragm body can be displaced in the second along this gap. According to the invention, the first diaphragm body (2) is mounted on a support element (3) and inserted from the unpressurized side into the second diaphragm body (4), which serves to mount the seal in the bearing mount (1), reaches around a pressure mount (5) on the unpressurized side and secures it against axial movement. The rotary shaft seal according to the invention can be used to seal shaft openings leading into vessels containing a pressurized fluid medium, particularly water pumps for internal combustion engines in motor vehicles.

摘要： The air damper includes a piston reciprocating within a cylindrical housing. The piston includes a lip seal which is coated with a minimum of 0.5%/seal part weight graphite powder/molybdenum disulfide. This provides for increased smoothness of operation of the air damper, particularly at low speeds.

摘要： Unitary radial lip seals are useful to provide permanent lubrication to rotary shaft and bearing assemblies. In addition, these seals also function as excluder seals to keep dirt, chemicals, and other contaminants from contacting the lubricated surfaces. However, previous radial lip seals have a tendency to wear or cut a groove into the associated rotary shaft, as the shaft is rotated during normal operation of the machine. The present disclosure describes a radial lip seal having a sleeve, a seal case, a faceplate and flexible member. This improved seal also has a second sleeve operably positioned between the shaft and the faceplate wiper ring that alleviates the tendency of the wiper ring to cut a groove into the shaft during normal operation of the machine.

摘要： A seal assembly seal assembly includes an outer member, an inner member, and a resilient member therebetwen. The resilient member is located between an inner diameter of the outer member and an outer diameter of the inner member. The resilient member includes substantially V-shaped or opposed parabolic members in cross-section which define a cavity therebetween. The cavity formed between the parabolic members is filled with the hydrophobic material to provide a barrier to undesirable moisture, lubricate the interface between the parabolic members and the outer diameter of the inner member, and further minimize ingestion of contaminants.

摘要： A radial lip seal for sealably mounting within a split circular seal housing includes a seal body having a channel disposed along a seal body outside diameter. The radial split seal includes an annular seal body which is divided into at least two substantially similar semi-annular seal body sections that are each connected together at end portions. The seal body formed from such sections includes a sealing lip that extends radially inwardly from the body for slidable sealing contact around a rotatable shaft. An energizer is seated within the channel. The seal is mounted within a seal housing that is configured to fix the axial placement of the seal therein. The energizer is interposed between the seal and the seal housing to both allow the seal to move radially a desired distance within the seal housing in response to seal thermal expansion and contraction, and to provide a leak-tight seal therebetween.

摘要： A lip type seal (3A) has an annular casing (31), a plurality of seal lips (32, 34) and a rear surface support ring (35) arranged at the rear side. The casing (31) is installed to an inner circumferential surface of a seal installation part (1a) of a shaft hole housing (1) of an equipment through a main gasket (36) made of rubber state elastic material. An inner circumferential part of the seal lips (32, 34) is closely contacted with an outer circumferential surface of a rotary shaft (2). A sub-gasket (41) made of a material having a CO2 transmission coefficient being smaller than that of rubber material is interposed between the rear surface support ring (35) and the shaft hole housing (1).
