摘要: A bonded part with a press-fit, vulcanized rubber member residing in compression between two rigid members and bonded thereto. The rubber member is a laminate with a core layer sandwiched between and bonded to two self-bonding rubber layers. The bonded part may be, for example, a vibration damper, isolator or absorber. The core layer and the self-bonding layers may have the same primary elastomer and cure system type, and the self-bonding layers have an adhesion promoter not present in the core layer. The adhesive layers may be from 0.05 to 1 mm thick or from 5% to 10% of the laminate thickness.The method includes forming a rubber core layer, curing it, applying a rubber adhesive layer on each side to form a laminate, inserting the laminate between two rigid members under compression, and post-curing to form a bonded part. The adhesive layers may be partially cured before inserting.

摘要: A coupling sleeve for use in a sleeve-type, flexible, shaft-coupling device, comprising: a generally annular body portion having an inner periphery and an outer periphery; and one or more axially extending, polymeric or elastomeric teeth on at least one of said periphery of said body portion; wherein said body portion comprises a rigid support band having a rigid, axially extending fin protruding radially into at least one of said one or more teeth. The coupling sleeve has a cross sectional area comprising a polymeric portion and a rigid band portion, and said rigid band portion occupies the minor portion of said cross section relative to said polymeric portion. Torque applied to the teeth of the coupling sleeve during use is resisted by the fins and the tooth material is thus placed in compression. Another aspect of the invention is to provide a coupling device comprising the coupling sleeve and at least one end piece coupled to said sleeve.
