摘要:
It is an object of the present invention to provide a hydrogenated nitrile rubber composition and a drivetrain oil seal whereby seal squeal can be prevented even upon wearing away of the sealing or even under dry lubrication conditions without any grease. The hydrogenated nitrile rubber composition of the present invention comprises 100 parts by weight of hydrogenated nitrile rubber and further 10 to 55 parts by weight of wollastonite and 10 to 55 parts by weight of graphite as fillers, the total amount of the fillers being 50 to 110 parts by weight. The drivetrain oil seal of the present invention comprises a crosslinked product of the hydrogenated nitrile rubber composition.

摘要:
Spring energized seal assemblies (100) each with one or two sealing elements (102) and a canted coil spring (120) located in a spring cavity (116) of the sealing element or of the two sealing elements to bias an inner flange (106) and an outer flange (108) of the respective spring cavity away from one another. The canted coil springs can have un-conventional coil shapes with one or more straight coil segments (150) and/or with curved connecting ends (152). The coils can have dimples (182) to provide multiple biasing points. The coils can have loops (170, 180). The canted coil springs with un-conventional coil shapes can be used to improve spring loading on a sealing element.
