    DESCRIPTION
    Elastic joint.
    Object of the invention.
    The object of the present invention is an elastic joint used to prevent premature wear of the machines and avoid stops or breakdowns, which has the characteristic of being entirely formed in metallic material and which has constructive particulars aimed at preventing the generation of noise and vibration transmission during operation.
    Scope.
    This elastic joint is applicable in all types of equipment and installations that must withstand radial, axial, torsional or conical forces; for example: explosion engines, industrial vehicles, trains, etc .; on the axle or on the support arm of all types of machines or all types of transport elements, the vehicle is installed on the support axis that joins the wheel with the suspension of the engine or with the chassis by means of an elastic joint; or at both ends of the shock absorbers of the vehicles; and in any other machine or installation that requires a joint.
    State of the art
    Currently, different elastic joints are used to replace certain mechanical joints, such as ball bearings, which have greater stiffness and do not absorb the high frequency vibrations that are the ones with the highest energy and therefore are likely to produce greater damage in The pieces to be insulated.

    Depending on their assembly in machines or transport elements, these joints can be subjected to forces in a single direction or to forces with components in different directions, for example: axial, radial, conical and torsional.
    In the state of the art, elastic joints are known which comprise two cylindrical metal reinforcements, concentrically arranged, and a mass of elastomeric material, usually rubber, compressed between the two reinforcements.
    The problem of these elastic joints that comprise a mass of elastomeric material is that they do not withstand the high temperatures generated in the operation of certain machines or transport elements; or to which these machines can be exposed when working in hot areas, such as foundries or furnace areas. For example, rubber supports a maximum of 80 °. Another drawback is that the rubber deteriorates in contact with acids or chemicals in general and cannot be used to withstand large loads.
    To solve the above problems, there are certain metal joints on the market, such as that described in US Patent 2,658,710, which places a cylinder-shaped shock absorber on the shaft or support, with a central bore.
    The problem with these joints is that they are suitable for absorbing stress only in the axial direction and do not provide adequate damping against radial, oblique or torsional loads.
    In European patent EP2077402 (HUTCHINSON, SA) a shock absorber for an aerospace structure is described which is composed of an annular chamber with compartments, each of these compartments being refilled by means of a metallic wire mesh cushion, the device completing a fluid of cushioning that fills the annular chamber and the spaces between the wire mesh.

    This elastic joint is complex to manufacture due to the incorporation of the damping fluid and the need to incorporate hydraulic seals or seals to prevent fluid leakage over time.
    In addition, this joint has only an axial elasticity, and does not provide adequate angular, torsional, or radial elasticity. In this background the rigidity is granted by the cushion and the damping is fluid.
    Document US 2 729 442 describes an articulation with deformable cushions to arrange between rotating elements, consisting of an outer jacket and an inner one with a square shape, between which deformable cushions are arranged.
    Description of the invention
    The elastic joint object of the invention has constructive particulars oriented to provide a high constructive simplicity, being formed entirely of metal materials, and can be used to withstand high loads and high temperatures, not suffering deterioration with the contact of chemical products.
    According to the invention, this elastic joint comprises:
    - an inner ring provided with an axial hole for the assembly of the joint on an axis to be damped and an external surface having at least two opposing intermediate sections, of decreasing section in the direction of opposite ends of said inner ring; and two extreme sections of smaller section than the connection point of the intermediate sections;
    - an outer ring, formed by at least two pieces facing in axial or radial direction, and having: an external surface for mounting the joint on a support to be damped and an internal surface with two intermediate portions of

    decreasing section towards the opposite ends of the outer ring and facing the opposite side sections of the inner ring and;
    - cushions made of metallic thread, forming a buffer and anti-friction means, arranged between the intermediate sections of the inner ring and the intermediate portions of the outer ring.
    These metallic wire cushions preferably have a quadrangular shape and are distributed around the intermediate sections of the inner ring, forming a plurality of contact points between said inner ring and the outer ring. These metallic thread cushions can withstand significant loads and, being metallic, provide cushioning without affecting the temperature.
    The intermediate portions of the inner ring can have different shapes, such as the conical trunk or polygonal pyramidal trunk, and different inclinations in order to provide different degrees of damping, always depending on the type of effort to be supported: axial, radial, oblique or torsional .
    In one embodiment of the invention, the intermediate portions of the inner ring have planes or recesses constituting seating areas and stabilization of the metal wire cushions, to withstand the torsional force.
    Both the intermediate sections of the inner ring and the intermediate portions of the outer ring are delimited by the opposite ends by means of projections that form retention stops of the metal wire cushions in the position of use of the joint.
    In an embodiment of the invention, the outer ring is constituted by two annular pieces intended to be mounted by opposite ends of the inner ring and to be threadedly engaged in the joint mounting position. This screw assembly allows the compression force to which the metallic wire cushions arranged between the inner ring and the outer ring are subjected to vary; with which a greater or lesser compaction of said cushions of elastic thread is achieved; Y

    consequently, a variation of the resistance to deformation of the elastic joint before different forces: radial, axial, conical and torsional.
    In a variant embodiment, the external surface for mounting the joint in the support to be cushioned is cylindrical.
    In a variant embodiment of the invention, it is provided that the inner ring disposes between the intermediate sections of a cylindrical central section; the joint comprising additional cushions of metallic wire mounted on said central section that significantly increase the resistance of the joint to radial loads.
