RUBBER-METAL DAMPER WITH INSERTS Russian patent published in 2012 - IPC F16F1/387 

FIELD: machine building.

SUBSTANCE: in the first variant the damper is made in the form of flexible element as a sleeve or flange sleeve or with flange, internal armature made in the form of cylindrical sleeve or rod. And the inner surface of the outer body is connected with flexible element due to the friction force. Flexible element is connected undetachably with ring inserts made in the form of sleeve or cut sleeve or sleeve segments. Ring inserts are made of polymer or composite material exceeding the rubber of flexible element in the elasticity modulus and antifriction and/or wearproof properties. The ring insert diameter is less than diameter of flexible sleeve. In the second variant of damper the flexible element is undetachably connected with internal metal sleeve the ends of which can be pressed and serve as fixing holes. Ring inserts are connected undetachably and detachably with flexible element. In the third variant of damper the flexible element is connected undetachably with internal armature which can be made as a sleeve with flat or profiled washer. Ring inserts are connected undetachably and detachably with flexible element.

EFFECT: reduction of radial movements of internal sleeve at the low values of axial damper hardness and increase of its resistance to actions of variable radial loads.
