    [0001] The present invention relates to the field of dampers for apparatus and tools and more particularly to the field of adaptable dampers for cutting and drilling equipment and tools. The mounting of tools on a suitable interface of the motor unit often involves an intermediate piece intended to limit the vibrations of the apparatus and the moving tool. In the case of a tool that operates in rotation, for example a cutting or drilling tool, vibrations may occur due to the resistance encountered by the cutting tool in contact with the material of the cut piece. These radial vibrations then come to parasitize the rotational movement of the cut piece relative to its axis of rotation. The intermediate damper then makes it possible to compensate for, or even cancel, the radial vibrations that can be produced by the rotating tool. Conventionally, this intermediate damper is formed by a cylindrical piece which provides a housing in which is disposed a cylindrical absorbent mass centered in the housing and held in position by elastic elements disposed on the periphery of the cylindrical mass, in contact with the wall internal cylindrical housing. This absorbent mass has the function of vibrating in phase shift with respect to the cylindrical part of its housing and thus damping the radial vibrations generated by the cut and in particular by the resistance encountered by the cutting tool. The damper / cylindrical mass assembly is then arranged to be aligned along the axis of rotation of the machine and the tool. The various elastic elements allow a damping of the vibration movements of the absorbent mass relative to the cylindrical part of the housing. This damping can be regulated by modifying the elastic hardness of the elastic elements and pre-binding them. However, the damping properties of this intermediate damper are dependent on the operating and operating conditions of the damper. Also, the quality of depreciation optimization can be affected by these influential factors. The present invention is intended to overcome these disadvantages by providing a damping device whose damping is able to adapt to one or more extrinsic factors to the damper and may affect the properties - 2 - Damping the device in operation, while ensuring an optimized stress or preload, effectively adjusted and controlled one or more elastomeric elements. The invention thus relates to a movable member for damping system 5 comprising an absorbent mass intended to be positioned in a housing and having, at the same zone, at least two adapted portions disposed on the periphery of the mass. absorbent and in which are disposed respective resilient members to abut against the inner wall of the housing, characterized in that these elastic elements have optimum damping properties in different ranges of variation of at least one parameter. Another subject of the invention concerns a damping system incorporating at least one mobile axial element according to the invention. The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which: FIG. 1 is a diagrammatic representation of an example of a movable axial element according to the invention, FIGS. 2 and 3 are two graphical representations schematizing respective examples of cooperation of the damping properties of different elastic elements of a mobile axial element of the FIGS. 4, 5 and 6 are diagrammatic representations of examples of arrangements of elastic elements of a mobile axial element according to the invention. In this document, the term "damping system" should be understood as referring to the part or assembly incorporating a shock-absorbing mass and intended to be mounted on a tool or a tool-holder to enable it. depreciation. The present invention relates to a movable element for damping system comprising an absorbent mass 1 intended to be positioned in a housing 2 and comprising, at the same zone, at least two adapted portions disposed on the periphery of the absorbent mass 1 and in which are arranged respective elastic elements -3- 3 intended to bear against the inner wall of the housing 2, characterized in that these elastic elements 3 have optimal damping properties in different ranges of variation of at least one parameter.
    [0002] In this document, the term "optimal damping properties" should be understood as referring to damping properties which, when quantified, correspond to at least 30% damping, ideally to a maximum damping value of 50% the temperature conditions.
    [0003] The damping is in particular dependent on the intrinsic properties of the elastic elements 3 resting on the periphery of the absorbent mass 1, namely, for example and in a nonlimiting manner, the elasticity or the viscosity. The equipment of an absorbent mass 1 of several elastic elements 3 whose respective respective damping properties different according to the value of an extrinsic parameter to the entire damping system, allows a coupling of these different damping properties by allowing optimized damping by the system over a wider range of values of the extrinsic parameter considered. Thus, according to an exemplary embodiment of a mobile element according to the invention, the mobile element is equipped, on the one hand, with a first elastic element 3a whose damping properties are optimal when the value of the extrinsic parameter is included in an interval AB and, secondly, a second elastic element 3b whose damping properties are optimal when the value of the extrinsic parameter is within a CD interval, the values AB and CD may either succeed or partially overlap . Also, during its operation, the movable element comprises at least one elastic element 3 whose damping properties are optimal over cumulative ranges of values. According to a preferred embodiment, the values B and C are combined so that, among its various elastic elements 3a and 3b, the movable element comprises at least one elastic element 3 whose damping properties are optimal over an extended continuous gap between the values A and D. Thus, if, during the operation of the mobile element, the extrinsic parameter, whose value is initially between A and B, changes to a value between C and D, this element mobile comprises permanently an elastic element 3 having optimal damping properties. The respective damping properties of each of the elastic elements are obtained by virtue of different compositions of each of these elements and / or by the presence of different concentrations of elastomers. Examples of different constructions of these elastic elements may be, for example, a particular arrangement of the elastic elements 3a and 3b on the absorbent mass according to their respective properties. Thus, according to a first nonlimiting example of construction, the movable element comprises several elastic elements. These elastic elements are then arranged on the absorbent mass 1 according to their respective properties.
    [0004] In the context of the explanation of the examples, to avoid any confusion concerning the properties of the elastic elements, the references thereof are replaced. In this first example of construction, some elastic elements 3c have a low elasticity and a high viscosity, while other elastic elements 3d, on the other hand, have a high elasticity and a low viscosity. The arrangement of the elastic elements 3c, 3d on the absorbent mass 1 is then performed by positioning elastic elements 3c with low elasticity and high viscosity at a first end of the absorbent mass 1 and elastic elements 3d with high elasticity and low viscosity at a second end, as shown in FIG. 6. Such an arrangement makes it possible to obtain an equal distribution of the damping properties for differential extrinsic parameters along the absorbent mass 1. During a damping operation the absorbent mass 1 then reacts identically at each of its ends as a function of the intrinsic properties of the elastic elements 3c, 3d located on the absorbent mass 1. Thus, the movable element has elastic elements 3c, 3d positioned on the mass absorbent 1 so that the elastic elements 3c arranged at a first zone situ e at a first side of the absorbent mass 1 have different properties of the elastic elements 3d disposed at a second zone located at a second side of the absorbent mass 1. According to a second example of construction, the distribution of the properties of the elastic elements 3 is homogenized along the absorbent mass 1 of the movable element. Thus, the arrangement of the elastic elements 3c, 3d on the absorbent mass 1 is operated by positioning the elastic elements 3c with low elasticity and high viscosity and the elastic elements 3d with high elasticity and low viscosity symmetrically on the absorbent mass 1 as illustrated in FIG. 5. Such an arrangement provides compensation for the properties of the various elastic elements 3 during damping with a homogeneous reaction of the absorbent mass 1 over its entire structure. Also, the movable element has elastic elements 3c, 3d having different properties at each zone intended to receive elastic elements 3c, 3d on the absorbent mass 1 so that all of these elastic elements 3c, 3d are disposed symmetrically on the absorbent mass 1 according to their respective properties. Alternatively, according to a third example of construction, the movable element can be made so that it has elastic elements 3c, 3d having respective different properties, these elastic elements 3c, 3d with different properties are arranged at each zone intended to receive elastic elements 3c, 3d on the absorbent mass 1 so that all of these elastic elements 3c, 3d is disposed asymmetrically on the absorbent mass 1 according to their respective properties. An example of this embodiment is illustrated in FIG. 4. According to a particular embodiment, the optimum intervals of variations of a respective parameter of each of the elastic elements 3 partially overlap. This partial superposition of the optimal intervals of variation thus allows the elastic assembly produced by the various elastic elements 3 coupled together to form an optimum range of widened variation. Thus, according to another exemplary embodiment of a mobile element according to the invention, the mobile element is equipped, on the one hand, with a first elastic element 3a whose damping properties are optimal when the value of the extrinsic parameter is in an EG interval and, secondly, a second elastic element 3b whose damping properties are optimal when the value of the extrinsic parameter is in a range FH, the values E, F, G and H succeeding each other. Also, during its operation, the movable element comprises at least one elastic element 3 whose damping properties are optimal for a value of the extrinsic parameter in the expanded range between E and H. In the interval formed by the values of parameter F and G, the two elastic elements 3a and 3b jointly have optimal damping properties. According to a first specificity of embodiment, the elastic elements 3 have optimum damping properties in different temperature ranges. According to a second specificity of embodiment, the elastic elements 3 have optimal damping properties in different intervals of displacement frequency. According to a third specificity of embodiment, the elastic elements 3 exhibit optimum damping properties in different intervals of impact resistance. According to a fourth specificity of embodiment, the elastic elements 3 have optimal damping properties in different ranges of moisture content.
    [0005] According to a fifth specificity of embodiment, the elastic elements 3 exhibit optimum damping properties in different ranges of displacement amplitude. According to a non-limiting feature of the invention and corresponding to the embodiment shown in FIG. 1, the movable element is characterized in that it has an axial shape and in that the adapted portions are formed by grooves. annular arranged at least radially on the periphery of the absorbent mass 1. Another object of the invention also relates to a damping system characterized in that it incorporates at least one movable axial element 30 according to the invention. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing as far as the field of protection of the invention.
