SPRING VIBRATION ISOLATOR WITH DRY FRICTION Russian patent published in 2018 - IPC F16F7/08 F16F1/362 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration absorber comprises a case in the form of a hollow vertical stand with a base cooperating with a T-shaped platform, which is elastically connected by means of elastic elements to a dry friction damper. Damper is made in the form of a sleeve whose inner surface interacts with the external surface of the post via spring-loaded friction elements. Spring resting on the base of the housing is fixed on the outer surface of the sleeve. Between the interacting surfaces of the sleeve and the rack a mesh damper is placed. Elastic mesh elements are made of a combined mesh frame filled with polyurethane. Elastic sleeve with a central hole is located in the central part of the mesh bag and is rigidly connected to the central plate. Support plates are attached to the plate. Upper and lower mesh elastic elements are connected respectively with the top cover and with the lower push plate of the package. In the center of each mesh elastic element a dry friction damper is located. Damper is a combined upper and lower sleeves, which form a friction pair. Elastic sleeve with a gap placed in the sleeves.

EFFECT: enabling increase in the vibration isolation efficiency in resonance mode.
