FIELD: machine building. ^ SUBSTANCE: elastic elements of a hanger are six identical flat curvilinear elastic rods with a cross section permanent in length. Rods are made in the form of a circumference arc with a certain radius of curvature. One end of each rod is rigidly fixed on an item casing so that fixation points lie on an imaginary sphere, the centre of which matches the item centre of mass. The other end of each rod is fixed on a rigid support ring, which is fixed on a casing of vibrations source. The ring plane passes via the item centre of mass. Three rods are arranged at one side relative to the ring plane, and the remaining three - at the other side. Each of the rod sets of three is installed symmetrically relative to the axis passing via the item centre of mass and perpendicular to the ring plane. The plane, where the axis of each rod lies in the initial state, is perpendicular to the ring plane and passes via the item centre of mass. The centre of curvature of each rod in the initial state lies on the straight line passing via the item centre of mass and the point of the rod fixation on the support ring. ^ EFFECT: vibration protection and protection against item strikes along all directions of linear and angular movements. ^ 3 dwg |
