Elastomer having tear reducing contoured edges

摘要

An elastomer damper including an elastomeric member laminated between two rigid plates. The elastomeric member having a first elastomer mating surface, a second elastomer mating surface, and a peripheral edge extending between each of the elastomer mating surfaces. Each elastomer mating surface is coupled to a respective rigid plate. At least a section of the peripheral surface is formed comprising a concave arch formed comprising one of a quarter ellipse or a dual quarter ellipse. The concave arch extends substantially between the elastomer mating surfaces. The concave arch shape reduces tearing of the elastomer damper. The dual quarter ellipse is formed by combining a first elongated first quarter ellipse and a second elongated first quarter ellipse in a continuous concave arched shape.

1. An elastomer damper comprising:
a first damper rigid plate having a first damper rigid plate elastomer contacting surface and; a second damper rigid plate being oriented generally parallel to the first damper rigid plate and having a second damper rigid plate elastomer contacting surface; and an elastomer element having a first damper rigid plate engaging surface, an opposite second damper rigid plate engaging surface and a peripheral surface extending between a circumferential edge of the first damper rigid plate engaging surface and a circumferential edge of the second damper rigid plate engaging surface, wherein at least a section of the peripheral surface is formed comprising a concave arch formed comprising a quarter ellipse, said elastomer element having longitudinal direction defined as being parallel to said damper rigid plate engaging surfaces and a lateral direction defined as being generally perpendicular to said longitudinal direction extending between said damper rigid plate engaging surfaces; wherein the elastomer is assembled mating the first damper rigid plate engaging surface with a surface of the first damper rigid plate and the opposite second damper rigid plate engaging surface with a surface of the second damper rigid plate.
