| 20080234080 | Motorcycle wheel isolator - A motorcycle wheel isolator comprising a first sprocket member, the first sprocket member having a first projecting member, a second hub member, the second hub member having a second projecting member, at least one first projecting member disposed between two second projecting members, whereby a receiving portion is defined, at least one resilient isolator having a first portion and a second portion connected by a connecting member, the resilient isolator disposed in the receiving portion, an edge of each first portion and second portion having a chamfer disposed adjacent either the first projecting member or second projecting member, each first portion and second portion having a projecting member disposed on an outer surface of each first portion and second portion such that a compressive force applied to the first portion and second portion causes a bending mode in each first portion and second portion, and each first portion and second portion having a relief portion disposed on an outer surface of each first portion and second portion such that the first portion and second portion may expand under the compressive force. | 09-25-2008 |
| 20090036609 | Rubber composition and vibration damper using the rubber composition - A torsional vibration damper or other vibration damping device with a rubber vibration absorbing element. The rubber element is a peroxide-cured composition based on 100 parts of ethylene-alpha-olefin elastomer, and 5 to 100 parts of polyvinyl butyral polymer which may have a molecular weight from about 40,000 to about 250,000. The composition may also include a compatibilizer or homogenizer, such as chlorinated polyethylene. The polyvinyl butyral increases the damping of the composition, and the compatibilizer improves the temperature stability of the damping. | 02-05-2009 |
| 20100137497 | RUBBER COMPOSITION FOR DYNAMIC PARTS - A rubber composition having (A) an elastomer component in which the primary elastomer constituent is an ethylene-propylene elastomer polymerized in the gas phase with a metallocene catalyst and having a molecular weight of at least about 250,000; (B) a silicon-modified olefinic elastomer in an amount of from about 5 to about 50 parts per hundred parts of the elastomer component; (C) ground mica in an amount of from about 2.5 to about 30 parts per hundred parts of the elastomer component; and (D) a peroxide curative. The composition may be used in a vibration isolator which may be used in a belt drive system. | 06-03-2010 |
| 20100159225 | METHOD FOR MAKING COMPOSITE ARTICLE WITH EXPANDABLE ELASTOMER IN COMPRESSION - A method of making a composite article includes providing an elastomeric composition with a blowing agent having an activation temperature and providing at least one structural member defining a fixed gap. The composition is formed below the blowing agent's activation temperature into a solid elastomeric member approximately the thickness of or larger than the gap. The elastomeric member is assembled into the gap, which may place the elastomeric member in a state of compression in the gap. The elastomeric member is then expanded by heating it above the activation temperature. During expansion, the escape of the gas produced is limited to increase the state of compression of the elastomer in the gap by means of confining any free surfaces or by including a platy filler such as nanoclay in the composition. | 06-24-2010 |
| 20100330352 | Bonded Part with Laminated Rubber Member and Method of Making - 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. | 12-30-2010 |
