摘要： A shaft seal that is preferably a radial shaft seal has a sealing element of polyfluorocarbon that is provided with a sealing lip. The sealing element contacts a surface to be sealed under a radial force action acting in a radial direction of the shaft seal. An elastomer element is provided that is acting on the sealing lip and loads the sealing lip in a direction toward the surface to be sealed. The elastomer element supports the sealing element. The sealing element is resting flat on a face of the elastomer element, wherein the face is facing away from a medium side of the shaft seal.

摘要： The inside of a planar, annular disk having a thickness of from about 0.8 to about 2 mm is cold flexed into a cylindrical, sealing stub about a shaft. For this, the inside diameter of the disk before cold flexing about the shaft is from about 1 to about 6 times the thickness of the disk less than the diameter of the shaft. A stiffening ring is sealingly attached about the outside of the disk with the line of the innermost attachment therebetween being from about 1.1 to about 4 times the thickness of the disk from the surface of the shaft.

摘要： A lip seal of elastic material has at least one sealing lip having a knife-edge sealing ridge particularly for sealing an axially moving part of a device from a liquid space, for instance in a galvanic metal-air cell. In order to improve the sealing of the axially moving device part with respect to the liquid space and to lengthen the sealing action, a membrane-like protective lip is formed on the liquid side in front of the sealing ridge, the lip resting with areal contact against the device part which is to be sealed off. The membrane-like protective lip due to its inherent tension or initial tension applies itself with high unit surface pressure against the surface of the device part to be sealed off.

摘要： An axial seal assembly is for sealing against a radial engagement surface of an outer member or an inner member disposed within a bore of the outer member. The seal assembly includes an annular case coupled with the outer member or disposed about the inner member and an annular elastomeric seal body. The seal body includes an inner portion attached to the case and an outer portion extending axially and radially from the inner portion so as to be positionable generally parallel to the radial engagement surface. The outer portion has a contact section extending generally axially from a remainder of the outer portion and being sealingly engageable with the radial engagement surface, the seal body outer portion being bendable about the seal body inner portion such that the seal body outer portion remains parallel to the engagement surface during axial displacement between the annular case and the engagement surface.

摘要： A leather flange for a bidirectional seal assembly includes a radial flange leg encircling a rotation axis of the leather flange. The leather flange also includes an oblique flange leg encircling the rotation axis and joined to the radial flange leg. The oblique flange leg extends both radially inward and axially away from the radial flange leg to form an oblique angle with the rotation axis. An end face of the oblique flange leg forms a sinusoidal pattern around a circumference of the leather flange. The end face also meets an air-side surface of the oblique flange leg to form a lip. When the leather flange is installed around a shaft, the lip forms a sinusoidal path around the circumference of the shaft. As the shaft rotates, the sinusoidal path of the lip creates an axial back-and-forth sweeping action.

摘要： A sealing device includes a metal ring 110 with a cylindrical section 111 and an inward flange section 112 disposed at one end of the cylindrical section 111. A resin seal 120 has an outer circumference side fixed to the metal ring 110 and an inner circumference side configured to slidably and closely come into contact with an outer circumference surface of the rotary shaft in a state deformed to curve toward a sealing target region. A flat spring 130 includes a plate-shaped annular metal member and has an outer circumference side fixed to the metal ring 110 and an inner circumference side configured to deform to curve along the resin seal 120 and press the inner circumference side of the resin seal 120 radially inward. A metal slide bearing 140, is sandwiched between the resin seal 120 and the inward flange section 112 and configured to slide on the outer circumference surface of the rotary shaft.

摘要： A seal includes a supporting ring and at least one sealing ring. The at least one sealing ring has a sheath. The at least one sealing ring and the supporting ring are interconnected. The supporting ring has an outer periphery and is, at least in part, surrounded on the outer periphery by the sheath of the at least one sealing ring in a radial direction. The at least one sealing ring has at least one dynamically loaded sealing lip, which is arranged on a side of the at least one sealing ring facing radially away from the sheath. The at least one sealing ring includes an electrically conductive polymer material. The sheath and the sealing lip transition into one another as one piece.
