International Classification:

B29C 4514

US Classification:

264138, 264161, 264275, 264279, 277569, 277575, 277402, 277924

Abstract:

A method of fabricating a fluid seal for sealing a relatively rotatable member, wherein the fluid seal has an elastomeric sealing member bonded to a PTFE insert. A wafer of PTFE material has a body portion and an end portion of a greater thickness than the body portion. The wafer is placed in a mold cavity with one side of the wafer opposed to a surface portion of the mold cavity. Elastomeric material is forced into the mold cavity to form a molded preform of the elastomeric sealing member and bond the preform to an opposite side of the wafer. The molded preform and bonded wafer are removed from the mold cavity. The end portion of the wafer and an end portion of the preform are trimmed to form the fluid seal.

International Classification:

F16C 33/76

US Classification:

384484, 277628

Abstract:

A seal, which has a core with a radially outwardly extending flange with an end surface and a sealing body with a sealing lip and an over-molded portion that extends radially outward beyond the flange and encompasses the end surface of the flange. Also, a bearing arrangement is disclosed which includes a bearing cup that has a counterbore with a conical inner surface, and a seal, which is contactable with the bearing cup, and has a core with a radially outwardly extending flange with an end surface and a sealing body with a sealing lip and an over-molded portion which extends radially outwardly beyond the flange and encompasses the end surface of the flange. The seal can be press-fit with the bearing cup such that the over-molded portion and the conical inner surface of the bearing cup are in tight contact with each other and form a static seal.

Assignee:

Federal-Mogul World Wide, Inc. - Southfield MI

International Classification:

F16J 1532

US Classification:

277569

Abstract:

A lip-type fluid seal (10) for a shaft includes a composite sealing lip (26) having an elastomeric portion (32) and a PTFE portion (36). The elastomeric portion (32) includes a lip edge (33) that extends circumferentially continuously to seal the adjacent lip edge (37) of the PTFE portion (36) from any contaminants on the elastomeric side (28) of the seal (10). The PTFE portion (32) has a greater hardness and modulus of elasticity which serves to limit the wear of the elastomeric portion (32) and to induce hydrodynamic surface deformations on the elastomeric lip portion (32) during operation to enhance the exclusion of contaminants. The PTFE lip edge (37) performs well under low temperature and/or low lubricity conditions and its relative hardness protects the elastomeric lip edge from excessive wear.

International Classification:

F16J 15/3252

Abstract:

A sealing assembly having a seal casing. A decreased diameter portion extends inboard from at least a portion of a first end portion of the substantially cylindrical portion and an axially extending portion extends inboard from at least a portion of a second end portion of the decreased diameter portion of the casing. One or more first sealing portions having one or more static sealing ribs extend from at least a portion of an outer surface of the substantially cylindrical portion. One or more second sealing portions are integrally connected to at least a portion of the decreased diameter portion, the axially extending portion and/or an inner surface of the substantially cylindrical portion. The one or more second sealing portions have a retaining member sealing surface with one or more sealing member retention ribs extending from at least a portion of an outer surface of the retaining member sealing surface.

Inventors:

- HERZOGENAURACH, DE
Stephen CARR - Troy MI, US

International Classification:

F16D 23/12

Abstract:

A clutch actuation device includes two plates that can selectively extend and compress relative to one another to selectively engage or disengage a clutch. Each plate includes a plurality of grooves, each groove having a deep end portion, a shallow end portion, and a ramped or inclined surface between the end portions. Each groove on the first plate corresponds with a respective groove on the second plate to define a plurality of pockets. Within each pocket is an elongated member having a pair of curved ends and an elongated shaft therebetween. The curved ends sit in the deep end portions of the grooves. To extend the plates relative to one another, the first plate is rotated relative to the second plate. This causes the curved ends of the elongated members to pivot within the deep end portions, and the elongated shaft extends away from the ramped surface, separating the plates.

Abstract:

A rolling bearing is provided that includes an outer ring having a first portion which includes a first raceway and a second portion that includes a second raceway that has a larger diameter than the first raceway. An outer diameter of the first portion of the outer ring is less than an outer diameter of the second portion of the outer ring. The rolling bearing includes an inner ring having a first portion that includes a first raceway and a second portion that includes a second raceway that has a larger diameter than the first raceway. An inner diameter of the first portion of the inner ring is less than an inner diameter of the second portion of the inner ring.
