VIBRATION ISOLATOR Russian patent published in 2002 - IPC

FIELD: mechanical engineering; different branches of industry. SUBSTANCE: vibration isolator has torus-shaped flexible member made of steel wire rope wound to form spiral and made of two similar- length interrupted parts one of which is made of right-hand twist wire rope, and other, of left-hand twist wire rope, and support plates-disks between which coils of wire rope are arranged and subsequently fixed. Pitch of coils of flexible member is equal to value at which clearance over circle between inner adjacent semicoils of torus is preferably not less than one millimeter when vibration isolator is under rated load. Vibration isolator is unidirectional device. Dissipation of vibrational energy and considerable reduction of disturbing forces transmitted to foundation plate are provided owing to friction between cores of steel wire rope. EFFECT: improved vibration isolation. 6 dwg
