A vibration dampening device, a mounting assembly including a vibration dampening device, and a method of dampening vibration in a vibration-sensitive component using the same. The vibration dampening device includes a first member that rests upon or is operatively engaged with a support surface; a second member that is operatively engaged with the vibration-sensitive component; and at least one isolator assembly interposed between the first member and the second member, wherein the first member and the second member are decoupled from one another by the at least one isolator assembly. The at least one isolator assembly includes a first isolator that is at least partially embedded in the first member and a second isolator that is at least partially embedded in the second member, and an isolator insert that extends between the first isolator and second isolator. The isolator insert creates a gap between the first and second members.

A buffer stopper capable of increasing an absorbable energy amount without causing changes in characteristics due to wear of a buffer body. In order to achieve the object, the buffer body containing a rubber elastic body disposed between an end surface formed in a housing and an end surface formed in a shaft which is relatively movable in the axial direction with respect to the housing and a wear resistant sheet which is provided so as to surround the outer peripheral surface of the buffer body and which can contact an inner peripheral surface of the housing by expansion and deformation in the radial direction of the buffer body are provided.

A vibration dampener for an archery bow includes an adjustable housing containing a chamber in which an elastomeric assembly is arranged. The assembly includes a cylindrical sleeve in which a central elastomeric member is arranged and a pair of elastomeric members coaxial with the central member at opposite ends of the chamber. The elastomeric members are pressurized to absorb vibrations in three dimensions from the bow during execution of an archery shot. The pressure applied to the elastomeric members is adjustable through use of a compression assembly.

The present invention relates to a displacement-controlled earthquake-resistant transformer employing a friction damper, including: a device body; an upper frame disposed in an upper portion of the device body to fix the device body; a lower frame disposed in a lower portion of the device body to fix the device body to a base while supporting the device body; and a friction damper unit disposed between the device body and the base to interwork with the device body and the base, and configured to buffer a vibration transmitted to the device body through the base fixed to a ground surface. According to the present invention, seismic energy is absorbed by using a frictional force of a damper in the event of an earthquake, so that damage that may be caused to the transformer by an earthquake shock is prevented.

A vibration damping assembly for use with an automotive vehicle is provided. The assembly includes a bracket having a C-shaped receptacle, a component such as an air cleaner housing having an integrally-formed, grommet-holding cylindrical post extending therefrom attached to the bracket, and a spool-shaped isolator mounting grommet attached to the post. The post includes a proximal end integrally attached to the component and a distal end. The distal end includes at least one integrally-formed retention barb and preferably includes two spaced-apart and integrally-formed barbs. The post includes an attachment end attached to the component and an unattached end opposite the attachment end. The barbs are formed on the unattached end. Each barb includes an upper edge extending beyond the unattached end of the post. Each barb includes a ramped, grommet-passing surface. The spool-shaped isolator mounting grommet may be formed from materials such as TPO, TPE, AEM, ECO, and EPDM.
