    专利说明:

    The invention relates to a means of depreciation of progressively moving objects and can be used in the design of buffers installed on moving trains, elevators, port stops, etc.
    A buffer is known that contains packets of elastic elements, each of which is made s in the form of successively installed rings of elastomer and D-metal disks cured to the last
    However, the known device does not provide a smooth depreciation of the object and has insufficient energy intensity.
    The purpose of the invention is to increase the energy intensity of the buffer.
    This goal is achieved by the fact that in a buffer containing packages of elastic elements, each of which is made in the form of a ring of elastomer and a metal disk cured to the last metal disk, the rings of adjacent packages are installed coaxially and have different damping characteristics.
    FIG. 1 shows the proposed buffer, longitudinal section; in fig. 2 shows an embodiment of the ring; in fig. 3 - hysteresis curve of elastomer deformation.
    The buffer contains packs of elastic elements, each of which is made up of internal and external rings 1 and 2 of the E5 elastomer and has attached metal disks 3 and 4 to them, each of which divides the elastomeric rings 1 and 2 into equal parts. For best bonding of rings 1 and 2 of elastomer c. Disks 4 and 5 in the latter are made evenly spaced around the circumference of the holes 5 and b, and the vulcanization elastomer fills these holes, and the diameters of the holes can be different. .
    The inner rings 1 are made of elastomer coaxially relative to the outer rings 2 and have different damping characteristics. The degree of damping of the outer and inner rings is higher and lower than 10%, and natural rubber can be used as such material.
    By the degree of depreciation T of an elastomeric material is meant the ratio of the energy absorbed by the mass of the material while continuously reducing it to the maximum value and the subsequent expansion of the material when the load is removed, to the energy accumulated in the mass of the material during one compression-depletion cycle. This degree of depreciation can be obtained from the hysteresis strain curve of the elathomer. FIG. Figure 3 shows the hysteresis curve, where the X-strain of the material is plotted on the abscissa, and the applied force is on the ordinate. Arc C corresponds to compression of the mass of the elastomer, and arc to tension.
    If we denote 5 the total area enclosed between the arc C and the abscissa axis, and 5-- the area in the form of the floor. month between arcs
    0 s and c, the depreciation rate T is equal to the ratio of the areas of 5 to S.
    The disks 3 and 4 are movably mounted on the central rod 7, having at one end a head 8 connected to one of the end disks 9 to which an external load from the cover 10 is applied. At the other end the rod 7 is threaded and has a nut 11, which creates
    Q preload packages of elastic elements of the buffer through the other, end face disk 12, which interacts with the base 13. Contact zones 14 inner rings 1
    with discs, 4 are designed in such a way that the absorption of impact is perceived by the rings 1 gradually and then expanded as the load increases, for which the rings 1 are made in the axial direction long and in the radial direction narrow. Inter-,
    The outer ends of the outer rings 2 and the discs 3 in the inoperative state provide an axial gap 15, which is gradually selected when the inner rings are deformed, and the outer rings 2 are thickened with respect to the rings 1, and therefore the external load perceived by the buffer F increases smoothly as the rings 1 and 2 are deformed.
    Rings 1 and 2 may have a different shape, for example, axially dissimmel-erythmal with respect to metal disks 3 and 4, and be made in the form of a cylindrical element 16 capable of working in a bend.
    Disks 3 and 4 can be made without a central hole, all the elements of the buffer are centered using a rigid outer casing or several rods parallel to the buffer axis (not shown}, and disks 3 and 4 can be not round, but rectangular.
    The frontal surface 17 of the rings 2, E interacting with the disks 3, may not be flat, but slightly corrugated around the periphery in such a way that the compression of the ring 2 upon application of an axial force to it will be constant.
    The buffer works as follows. When a blow is applied to the lid 10. a smooth deformation of the rings 1 takes place until a gap 15 is selected, and
    Then the deformation of the rings 2 occurs if the blow is sufficiently strong. After removing the impact due to the elasticity of the rings 1 and 2, the buffer elements return to their original position, giving back the energy accumulated during the creep.
    The proposed buffer, in comparison with the known buffer, provides a wide range of perceived loads, since it can absorb shocks in a wide range of loads, and in addition, it is simple to manufacture and assemble.
