VIBRATION INSULATOR Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: vibration insulator has housing made up as flange and support. Outer cylindrical screw spring, bushing, inner cylindrical screw compression spring, and damping ring are coaxially arranged between the flange and support. The spiral groove is made in the outer side of the bushing. The outer spring is received in the groove. The stop for the second spring is mounted on the inner side of the bushing. The rigidity of the inner spring and rigidity of the outer spring relate as 15-25. The width of the spiral groove is 1.5-3 times greater than diameter of the wire of the outer spring. EFFECT: improved vibration insulation. 2 cl, 1 dwg
