VIBRATION ABSORBER OF QUASI-ZERO STIFFNESS Russian patent published in 2014 - IPC F16F3/02 F16F15/06 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building. A vibration absorber consists of a loading resilient member, a stiffness corrector with levers, a loading platform for installation of equipment with its vibration to be absorbed and connection elements. Force in the stiffness corrector is adjusted by a separate resilient member. Vibration absorber as per the first version implies that the odd number of linear springs which are set symmetrically to the stiffness corrector axis is used as the loading resilient member. Vibration absorber as per the second version implies that the odd number of linear springs is used as the loading resilient member; the even number of them shall be set symmetrically to the stiffness corrector axis and one spring shall be placed strictly along its axis. Vibration absorber as per the third version implies that the even number of linear springs which are set symmetrically to the stiffness corrector axis is used as the loading resilient member.

EFFECT: improved manufacturability, efficiency and reliability of a vibration absorber, usage versatility for different types of equipment whose vibration shall be absorbed.
