COMBINED SPRING WITH ELASTIC-DAMPING DEVICE Russian patent published in 2018 - IPC F16F3/10 

FIELD: machine building.

SUBSTANCE: invention refers to the machine building. Spring is made cylindrical helical, and consists of two parts with opposite directed ends. First spring part has with turns of rectangular section and rounded edges, and second part is made hollow. First part opposite directed end is located in the second part cavity. Spring contacting parts segment profile gaps are filled with antifriction grease. To prevent the grease leakage at the second spring part end sealing collar is installed. Helical spring first part is enclosed by tube from damping material. Gaps in the helical spring first part, which is covered by the tube of damping material, are filled with the sintered friction material crumb. On the spring support coils mounting rings are made. On support rings vibration dampening plates consisting of the elastic and vibration dampening materials alternating layers are fixed.

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