VIBRATION INSULATION SUSPENSION Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: vibration insulation suspension has top and bottom horizontal plates and flexible members interposed between them and secured to them over peripheries the centers of which are coincident with the vertical axis of symmetry of the suspension. The flexible members are made up as cylindrical compression springs the length of which as well as the diameter of a wire and diameter of turns are chosen to provide quasi- zero rigidity of the system of the springs in the horizontal plane over all degrees of freedom. The rigidity compensator is made up as an armature secured to one of the plates and a magnet made up as a ring and interacting with it. The ring is secured to the other plate and additionally has magnetic circuits secured to the end faces of the magnet and U-shaped slides. The armature is made up as a horizontal flat ring mounted inside the U-shaped slides with a spaced relation. The space corresponds to calculated working displacements of a vibration object. The centers of symmetry of the armature, magnet and magnetic circuits are at the axis of symmetry of the suspension. The armature may be secured via compression-expansion springs the ends of which are secured to the armature and plate, respectively. The working surface of the armature that interacts with the slides may be covered with a layer of a nonmagnetic material. The loop-shaped portion of the slides is made of a nonmagnetic material. EFFECT: improved vibration insulation. 4 cl, 9 dwg
