SPATIAL FRAME TYPE VIBRATION ISOLATOR WITH PARALLEL RESILIENT-DAMPING ELEMENTS Russian patent published in 2018 - IPC F16F3/10 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator contains a frame in the form of two supporting horizontal plates, supported by resilient damping elements mounted on a common base. Horizontal plates are rigidly connected to the vertical plates, which in the frame lower part are connected together by the base plate. Platform for a vibration-insulated object is installed on the base plate through a vertical stand. Left elastic-damping element is made in the form of a cylindrical helical spring consisting of two parts with oppositely 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 first part of the spring are filled with crumb of friction material. Vibro-damping plates are fixed on the upper and lower support rings to fix the ends of the springs during their operation. Right elastic-damping element is made in combination.

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