FIELD: machine building.
SUBSTANCE: invention relates to machine building. Vibration isolator consists of successively connected and coaxially arranged rigid shells of truncated cone: upper and lower. In each shell, elastic damping element is coaxially arranged. Upper base of each of the shells is a hard drive connected to them. Disk is supported by upper ends of elastic-damping elements. Lower base of each shell is open for installation of elastic elements. Inclined elastic elements are located in peripheral part of shells. Vertical elastic elements with their upper ends are connected with lower end of lower shell, and lower ends – with base. Elastic elements are installed in planes with a shift of 90°. Upper resilient damping element is made in form of cylindrical helical spring, turns of which are covered with polyurethane. Lower elastic-damping element is made in form of combined spring with torsion damper. Inclined elastic elements are made in the form of disc-shaped elastic elements.
EFFECT: enabling increase in the vibration isolation efficiency.
