The invention relates to the field of devices for reducing vibration and shock (shock absorbers) and can be used for designing vibration and shock protection for various technical systems and devices, mainly in the engineering and shipbuilding and mechanical engineering.

Currently, there are various dampers: A.S. USSR №607943, No. 832033, RF patents №2229637, No. 2237793, French patent No. 1592216, CL B60G 11/00, 1970. In the book "Cyril M. Harris, Charles Icrid "Handbook of shock loads". Leningrad: Sudostroenie, 1980, s-313" presents various schemes of shock absorbers.

Closest to the claimed solution (prototype) is a device by RF patent No. 2358166. This shock absorber, containing connective crowdeye elements, between which is inserted a rubber element and the rubber element is designed as a cylinder with a Central through hole and a blind end holes parallel to its symmetry axis. First crowdedi element is designed in the form of a ring of rectangular cross-section, covering the circumference of the cylinder of the rubber element. The second is in the form of a stepped cylindrical liner, the plane of the stage which coincides with the plane of one end of the cylinder of the rubber element. The plane of the second end of the cylinder rubber ale the NTA in the same plane as the end face of the first kilowattage element.

The disadvantage of this shock absorber is the design complexity. The proposed solution allows to eliminate the deficit and to simplify the design of shock absorbers of this type.

The technical problem on which the invention is directed is the provision of RangeStart shock absorber in mutually perpendicular directions while simplifying, reducing dimensions, material consumption and increasing the structural strength.

The technical result is achieved due to the development of the shock absorber, the disc which is fixed on depreciable items, and the elastic ring is fixed on the disk, forming the petals of the shock absorber. Ring shock absorber is of resilient, elastic material, for example, metal, polyethylene, Teflon-4, etc.

The claimed solution is illustrated by drawings.

Figure 1 shows the components of the shock absorber: disk 1 and the ring 2. The stiffness of the shock absorber is determined by the material of the ring, as well as the geometrical dimensions: D1 - diameter disk D2 is the diameter of the ring, b is the thickness of the ring, H - width of the ring.

Figure 2 shows the options for mounting the ring on the disk. The more attachment points, the more petals shock absorber, especially ravnodusnim the result is a shock absorber. Usually enough for 3-4 petals. The ring is attached to thesis is the screws, screws, screws, welding, soldering, or fabricated (casting or pressing) as a single product (figure 2, b).

Figure 3 shows the options for mounting the disk on depreciable items. When this drive is a slot corresponding to the contour of a part.

Figure 4 shows the shock absorber in a free state (dotted line) and the absorber is placed in the cylindrical housing. Initially, the petals of the shock absorber are beyond the contour of the hull. For placement in the housing of the shock absorber should deform by compression of the petals to the center of the disk. The more petals initially protrude from the housing, and the stronger the required deformation of the petals to place the shock absorber in the body, the harder will be to operate the damper.

Figure 5 shows the placement of the shock absorber in buildings of different profile.

Thus, the proposed design allows you to create very simple to manufacture, compact ravenously and pliable shock and to obtain the technical result of the proposed invention consists in the provision of RangeStart shock absorber in mutually perpendicular directions while simplifying, reducing dimensions, material consumption and increasing the structural strength.

The absorber containing the disk and a deformable ring, characterized in, Thu the disc is attached to depreciable items, why it has a slit (opening) of the corresponding profile, and the deformable ring is attached to the disk at several points, creating the petals of a shock absorber, and due to its elasticity absorbs energy during vibration and shock.
