VIBRATION ISOLATOR OF SPRING TYPE Russian patent published in 2016 - IPC F16F3/10 

FIELD: machine building.

SUBSTANCE: vibration isolator comprizes base, flexible elements and support assemblies. Flexible elements are made in the form of a pack of top and bottom arc-type flexible elements facing towards each other. Each of packages is made in the form of a set of alternating in mutually perpendicular directions of flat springs. Each flat spring consists of horizontal flange and two side flanges, bent by 135° angle to horizontal flange and provided with thrust sections at ends. Damping element of the vibration isolator is made combined and consists of friction and elastic parts. Friction part is made in the form of bushings with flanges on ends and a piece of rope wound along closed circuit of the bushing. Bushes are coupled with resilient elements by rivets. Elastic part is made as flexible damping ring embracing the rope section from outiside. Additional flexible element is located inside the packages of the resilient elements and rigidly fixed by means of glue composition between heads of bolts. Bolts are fixed on flexible elements by means of nuts.

EFFECT: improved efficiency in resonant mode of vibration isolation.
