FRICTION VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F7/09 

FIELD: machine building.

SUBSTANCE: vibration isolator includes an elastic element, a housing and a dry friction damper. Housing is made in the form of bottom sleeve and top cover, between which axially symmetrical to the housing an elastic element is located, inside which the dry friction damper is arranged. In the housing bottom sleeve, the damper bottom frictional bushing is coaxially fixed. Damper is made in the form of the top sleeve with the frictional force adjustment mechanism between the bottom friction bushing and the top friction bushing, located in the damper damping force adjustment mechanism. Frictional force adjustment mechanism consists of threaded bushing connected to the top sleeve inner threaded surface. Inside the threaded bushing, a rigid tapered pin is coaxially secured, contacting with the conical bushing, by three tabs connected to the damper top sleeve. From the inside, bushing and tabs are covered with the copper based sintered friction material layer.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
