Description

  

  Pompe à eau comportant une roue à. ailettes.    La     présente        invention    a pour objet une  pompe à eau     comportant    une roue à     ailettes     et destinée, par exemple, à la circulation de  l'eau dans     les        moteurs    à combustion     interne.     



  La pompe selon l'invention est caracté  risée en ce que l'arbre portant la roue à     ai-          lettes    est monté dans un palier à     rotule    et en  ce que l'étanchéité entre cet arbre et le     coTps     de pompe est assurée par un palier anti  friction, les     surfaces    en contact de ce palier  étant     formées    par des parties de sphère de  même rayon, dont les     centres    coïncident avec  le     centre    du palier à rotule, autour duquel  l'arbre de la roue à     ailettes    oscille pour se  placer dans l'alignement,

   ces     surfaces        étant          maintenues    appliquées l'une sur l'autre par  un     .ressort    et     formant    entre elles un joint  étanche à l'eau.  



  Le dessin     ci-annexé        représente,    à titre  d'exemple, une forme d'exécution de l'objet  de l'invention. L'unique     figure    de ce dessin    en est une vue en coupe long     tudinale    par  tielle.  



  L'arbre a portant la roue à     ailettes    b est       monté    dans un     palier    à rotule à billes c, le       centre    de la     surface    sphérique d de ce palier  étant situé au     point    e, lequel est le centre au  tour duquel     l'arbre    a oscille pour se     placer     dans l'alignement.  



  L'arbre     présente    un collier f qui pour  rait aussi     être,    monté sur lui, et dont une     face     présente la forme d'une     partie    de sphère dont  le     centre    est au     point    e,     cette    face appuyant,  sous l'action d'un ressort<I>f 1,</I> sur     im    anneau<I>g</I>       serti    dans un     logement    de la paroi du corps  de pompe traversée par l'arbre.

   Cet anneau  g est en     charbon    ou en     un    autre matériel ou  métal     antifriction    et la face en contact avec  le collier f de     cet    anneau présente aussi la  forme d'une     partie    de sphère, dont le     centre     est au     point    e.

        II     résulte    de la     conformation        susdéerite          des        surfaces    en     contact    des organes f et g et  de leur position par rapport au     centre,    au  tour duquel oscille l'arbre a pour se     pla:

            ccr    dans l'alignement, que le mouvement de  l'arbre a dans son palier c ne produira     pas     une usure irrégulière de l'anneau de     charbon     ou d'antifriction.     C'est    ainsi que l'on obtient  un fonctionnement     efficace    et de longue du  rée des     surfaces    en     contact    formant entre  elles un joint étanche à l'eau, des organes f  et g et de la sorte un bon joint     étanche    à  l'eau     entre        l'arbre    et le     corps    de la pompe,

    joint qui ne     nécessite    aucune     surveillance    du  rant de longues périodes.  



  En     raison    du fait que l'arbre a peut se  mouvoir pour se     placer    dans l'alignement  sans nuire aux     surfaces    en contact des or  ganes f et g, l'arbre de     commande        représenté     en<I>h,</I>     qui        entraîne    en     rotation    l'arbre<I>a,</I> n'a       pas    besoin d'être exactement aligné avec  l'arbre     ca;    ces deux arbres ont la     liberté,    dans  une     certaine        mesure,    de se mouvoir l'un par  rapport à l'autre.



  Water pump comprising an impeller. fins. The present invention relates to a water pump comprising a paddle wheel and intended, for example, for the circulation of water in internal combustion engines.



  The pump according to the invention is characterized in that the shaft carrying the vane wheel is mounted in a spherical bearing and in that the seal between this shaft and the pump head is ensured by an anti-friction bearing. friction, the contacting surfaces of this bearing being formed by parts of a sphere of the same radius, the centers of which coincide with the center of the spherical bearing, around which the impeller shaft oscillates to be placed in alignment ,

   these surfaces being held applied to one another by a spring and forming between them a watertight seal.



  The accompanying drawing represents, by way of example, an embodiment of the object of the invention. The only figure in this drawing is a long sectional view of it.



  The shaft a carrying the impeller b is mounted in a spherical ball bearing c, the center of the spherical surface d of this bearing being located at the point e, which is the center around which the shaft has oscillated for get in line.



  The shaft has a collar f which could also be mounted on it, and one face of which has the shape of a part of a sphere whose center is at point e, this face pressing, under the action of a spring <I> f 1, </I> on an <I> g </I> ring crimped in a housing in the wall of the pump body through which the shaft passes.

   This ring g is made of carbon or another anti-friction material or metal and the face in contact with the collar f of this ring also has the shape of a part of a sphere, the center of which is at point e.

        It results from the aforementioned conformation of the surfaces in contact of the members f and g and from their position with respect to the center, around which the shaft a oscillates to place itself:

            ccr in alignment, that the movement of the shaft a in its bearing c will not produce irregular wear of the carbon or anti-friction ring. This is how efficient and long-term operation of the contact surfaces forming between them a watertight seal is obtained, the members f and g and in this way a good watertight seal between the shaft and the pump body,

    seal that does not require long-term rant monitoring.



  Due to the fact that the shaft a can move to place itself in alignment without harming the contacting surfaces of the organs f and g, the drive shaft shown in <I> h, </I> which drives in rotation the shaft <I> a, </I> does not need to be exactly aligned with the shaft ca; these two trees have the freedom, to a certain extent, to move in relation to each other.
