DAMPER OF ENERGY Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: energy damper has housing, bushing and deforming rod with a collar axially alined with the housing, and thread provided on the inner side of the bushing. The groove in the collar receives a spiral insert of the same shape that is mounted on the rod with a space relation. The end face of the insert abuts against the collar of the rod. The spiral insert is deformed. The diameter of the rod is equal to the inner diameter of the thread of the bushing. The spiral insert is mounted on the rod to provide initial radial pressure.
