VIBRATION ISOLATOR FOR OBJECTS WITH AN OFFSET CENTER OF MASS Russian patent published in 2018 - IPC F16F15/08 F16F7/01 F16F1/362 

FIELD: machine building.

SUBSTANCE: invention relates to mechanical engineering. Vibration isolator contains an elastic element, a cover and a base. System for adjusting the rigidity of the elastic element is made in the form of a flexible connection, one end of which is intended to be fixed to the object, and the other end is mounted to the lid, with the possibility of moving along and locking it. On the lid guides are made in which a creeper is placed in which the other end of the flexible connection is fixed. In the cover are made holes, through one of which the other end of the flexible connection is missed and fixed on the base. Elastic element is made in the form of a combined vibration damping spring. Spring is made helical and consists of two parts with opposite ends. First spring part is fitted with turns of rectangular section and rounded edges and second part is made hollow. First part on-coming end is located in the second part cavity. Spring contacting parts segment profile gaps are filled with antifriction grease. Sealing gasket is mounted at end of second spring part to prevent grease leakage. First part of helical spring is enclosed by tube from damping material. Gaps in first part of helical spring, which is enclosed by tube from damping material, are filled with friction material crumb.

EFFECT: increase in effectiveness of vibration isolation is achieved.
