VIBRATION ISOLATOR WITH ROPE DAMPER Russian patent published in 2016 - IPC F16F3/10 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator comprises flat resilient and friction damping elements. Flat resilient elements are made as a package of arc-type resilient elements consisting of flat springs alternating in mutually perpendicular directions and resting against a base. Each flat spring consists of horizontal flange and two lateral flanges bent at angle 135° to horizontal flange and provided with thrust sections at ends. Damping element is a compound one and consists of a friction part and an elastic part. Friction part is made as bushes with flanges at ends and a section of a rope wound on bushes in a closed loop. Bushes are coupled with resilient elements by rivets. Elastic part is composed of resilient damping ring from elastomer embracing outside pigtail. Sleeves are made hollow from elastic material. Cavity between inner surfaces of sleeves and external surfaces of rivets are filled with vibration damping material, for example polyurethane. To friction parts of damping element is fixed plate of vibration dampening material, for example polyurethane.

EFFECT: higher efficiency of vibration isolation.
