Definitions

  • Pivot member means an axis or barrel for receiving an axis.
  • the document EP1850193 proposes a method of driving a first piece in a second piece without plastic deformation, comprising introducing into a first hole of the second piece a deformable intermediate piece comprising a second hole, and driving the first piece into the second hole so as to tighten the intermediate piece against the wall of the first hole by deformation of the intermediate piece.
  • the present invention aims to provide a method of assembling a hard part on an axis or, more generally, on a pivot member, free from the above disadvantages.
  • pivot member this term encompassing various parts intended to be assembled to a mobile to allow the rotational mounting of the latter.
  • the pivot member may be an axis 10, having a tubular portion and whose unrepresented ends form pivots.
  • the axis 10 comprises a cup 12 extending radially about the axis 10.
  • the cup 12 defines a bearing surface. It can be disk-shaped.
  • the cup is provided on one of its faces with an annular recess 14 located around the axis.
  • the shape of the hollow is indifferent. Particularly to the method described in this example, the recess is located immediately at the base of the axis, with at least one open area on the axis.
  • a malleable element typically a malleable washer 16 of generally annular shape, is also used in the method according to the invention.
  • This washer 16 may be metallic or synthetic and possibly have elastic properties. It is likely to be deformed by creep, cold or hot, by the application of a mechanical stress.
  • a material in the pasty state, which can be deformed and then stiffened, for example by polymerization, can also be used.
  • This washer 16 is dimensioned so as to take place in the recess 14. It thus comprises a central opening, intended to allow the introduction of the axis 10.
  • the central opening is circular, a diameter slightly more large than the outer diameter of the axis 10, allowing a free positioning of the washer 16.
  • the shape of the outer contour of the washer 16 is indifferent, it must simply be adapted to the shape of the recess 14. In this example, the thickness of the washer 16 is greater than the depth of the recess 14, so that the washer 16 protrudes therefrom.
  • the hard part 18 there is a hard part 18, without a plastic field or with a small plastic field, made of materials having a hardness typically greater than 500 Vickers.
  • the hard part 18 may in particular be made of silicon, diamond, nickel or steel.
  • the piece 18 may, for example, be a wheel or a rocker, intended to be assembled on the axis.
  • the hard part 18 has a through opening, whose shape is adjusted to that of the axis 10 to be inserted freely on the axis. Depending on the accuracy of the positioning of the desired part, it can have a slight play or a slight elastic strength, but without applying radial stress on the hard part 18.
  • the latter still has at least one housing 20 defining an inlet, positioned so as to open opposite the washer 16.
  • the hard part 18 is traversed by two tubular orifices, preferably cylindrical, playing the role of housing.
  • a cover 22 may also be provided. It has an opening sized to allow a driving on the axis 10.
  • the dimensions of the cover 22 are typically similar to those of the cup 12, in order to hide the visible parts of the assembly. resulting from the method and further allowing to balance the assembly. Note that in the case where the washer 16 is made of a resilient material, the cover is particularly important to ensure the axial positioning of the washer with reference to the pivot member.
  • the washer 16 is placed in the recess 14. Then, the hard part 18 is mounted on the axis 10 and is pressed against the washer 16 which protrudes from the recess 14. Thanks to the fact that , as described above, the opening of the housing 20 is located opposite the washer 16, the pressure exerted on the part 18 is sufficient to cause the flow of the washer 16 inside the housing 20. This induced deformation the creation of pins 24, parts of the washer 16 and deformed, inserted without degree of freedom in the housing 20 of the part 18. The part 18 and the washer 16 are absolutely integral in rotation.
  • the washer 16 being positioned near the axis 10, the pressure exerted on the washer 16 also induces, as shown in the figures, a deformation of the washer 16 in the direction of the axis 10. The latter is located thus strongly tightened by the washer 16.
  • the hard part 18 is fixed on the axis 10, without degree of freedom.
  • the force to be applied to the hard part 18 to separate it from its axis has a component relating to the shear stress required to break the lugs 24.
  • shearing which exerted on the lugs 24 during the rotation of the part, which allows a better distribution of the constraints related to the applied torque.
  • FIGS. 2a and 2b show another embodiment of the invention, wherein the pivoting member is a barrel 26 having a tubular portion and intended to receive an axis 28.
  • the barrel 26 is provided with a cup 12, like what has been described above with reference to the figure 1 , provided with a recess 14 for receiving a washer 16.
  • a hard part 18 is freely assembled on the barrel 26, in a manner similar to that described with reference to FIG. figure 1 .
  • a cover 22 has been used to mask the visible parts of the assembly resulting from the process.
  • an independent and functional assembly is obtained, comprising the barrel 26, the washer 16 and the hard part 18, with, possibly the cover 22.
  • the shaft 28 can then be mounted inside the barrel 26 but, as will be understood, it is not the axis of the hunting that allows the holding of all previously mentioned.
  • the figure 3 also illustrates an implementation of the invention with a barrel 26.
  • the axis directly comprises a mobile 30, acting as a lid.
  • the mobile is a wheel or a pinion gear.
  • the barrel 26 does not protrude beyond the hard part 18, so that, after the assembly of the axle 28 and the mobile 30, the latter bears against the hard part 18, without gap between the two elements .
  • the Figures 4a and 4b represent a further implementation of the method according to the invention.
  • the washer 16 does not need to protrude from the recess 14.
  • the thickness of the washer 16 is preferably equal to or close to the depth of the recess.
  • At least some of the housings 20 in the room 18 are through.
  • the cup 12 is provided with cavities 32, at least some of which are through, opening out facing the washer 16.
  • the housings 20 of the hard part 18 and the cavities 32 of the cup 12 are positioned so as to be screwed two to two.
  • the washer 16 first, is arranged in the recess 14, then, the hard part 18 is disposed on top, so that the housing 20 of the hard part 18 and the cavities 32 of the cup 12 are in opposite two to two.
  • Those skilled in the art can provide an indexing means for easily orienting the two elements one with reference to the other.
  • a tool 33 is passed through the cavities 32 and the through-holes 20 of the cup 12 and, respectively, of the hard part 18, which are therefore accessible and pressure is exerted on the washer 16.
  • the latter will flow in the housings 20 of the hard part 18 and, respectively, in the cavities 32 of the cup 12 to form lugs 24.
  • the piece 18 lasts and the cup 12 of the pivot member are thus perfectly secured, with no degree of freedom between the two.
  • the recess 14 is located immediately at the base of the tubular portion of the pivot member.
  • the washer 16 may also be of any shape. Indeed, the lugs 24 created inside the cup directly ensure the connection of the washer with the pivot member.
  • the deformation of the washer 16 can be done thermally, for example by melting the washer, during which under the effect of the pressure applied, the material of the washer 16 simply flows into the housings 20 of the hard part 18 and, where appropriate, in those of the cup 12.
  • the washer 16 is fixed on the cup 12 in a step independent of the deformation step of the washer 16.
  • the washer 16 can be glued, welded, brazed, or directly deposited electrically on the cup. In such cases, it is not necessary to arrange the washer 16 so that it is secured to the tubular portion of the pivot member during the deformation step of the washer, as mentioned above. above.
  • the Figures 5a and 5b illustrate a further variant of the method according to the invention, wherein the hard part 18 is freely mounted on the tubular portion of the axis 10.
  • the washer 16 is dimensioned so as to be driven on the axis 10 In particular, it is sufficiently thick so as to withstand the mechanical stresses induced by such a driving, the thickness being a function of the strength of the material.
  • the washer and the tubular portion are secured by driving.
  • the washer 16 comes into contact with the hard part 18, the washer is pressed against the hard part so as to flute the washer 16 in the housings that comprises the hard part 18 and create the lugs 24.
  • the Figures 6a, 6b, 6c and 6d propose different examples of housing 20 achievable on a hard part, inside which can form the lugs 24 from the washer.
  • the figures show a hub 34 of a mobile.
  • the housings 20 may consist of openings, of any closed shape, made on the hub 34.
  • the housings may also be of open shape, around the inner or outer periphery of the hub 34.
  • the housings 20 are then notches, plus or less crenellated.
  • the housing arrangement can be used, preferably, so that the center of gravity of the mobile is aligned with the axis of rotation.
  • the housings are preferably distributed over the part of the hard part 18 intended to face the washer 16.
  • the figure 6d shows a particular hub structure, having an open elastic structure to be assembled on the axis.
  • Each spoke of the wheel ends at the center of the wheel at a clamping zone 36, forming the hub of the wheel.
  • Slits 38 oriented radially separate two consecutive clamping zones.
  • the slots may eventually lead, on the side of the center of the wheel, in a notch similar to those of the Figure 6c .
  • these clamping zones are also provided with housing 20.
  • the term "punctual" refers to a surface or limited space around a specific point, as proposed by tubular housing. These structures can be regular or irregular, carried out by techniques of sanding or sunning.
  • the malleable element, deforming, penetrates inside the structures formed on the surface of the hard part and thus provides a multitude of small lugs.
  • FIGS 7a to 7f show different profiles used to make the recess 14, to guide the direction in which the material constituting the washer will flow.
  • the example of figure 7a is the simplest, with a hollow whose bottom is flat.
  • the bottom of the hollow is in the form of a rib, defining a first inner flank 14a leaning on the side of the center of the puck, and a second outer flank 14b leaning on the outside of the puck.
  • the Figures 7c and 7d propose a bottom with a single flank, leaning respectively 14c towards the center and 14d from the outside of the washer.
  • the bottom of the recess is flat, but an inner groove 14e and an outer groove 14f are defined by the edges of the bottom of the recess. In other words, the hollow is wider at its bottom.
  • the figure 7f illustrates the way in which cavities 32 through or blind can be formed in the bottom of the recess.
  • the bottom of the recess can also be structured, just like what is proposed above about the hard piece. This reinforces the interaction between the malleable element and the pivoting member.
  • the skilled person may still consider other variants, without departing from the general scope of the invention, delimited by the claims.
  • a malleable washer on the cup, without the latter having a recess, since the dimensions of the washer, both in thickness and in surface area of contact with the bearing surface, are adapted.
  • Such a solution is illustrated on the figure 8 .
  • the recess may not be annular.
  • the bearing surface may have a plurality of recesses distributed around the tubular portion.
  • Malleable elements are arranged in these recesses to cooperate with correspondingly positioned housings in the hard part.
  • the malleable elements may be of any shape. Indexing means may be provided for positioning the malleable elements and the housing facing each other.
