Description

  

      Joint        universel       L'objet de la présente invention est un joint uni  versel destiné à     relier    deux arbres entraînés en rota  tion et dont les axes concourants forment l'un par  rapport à l'autre un angle.  



  La présente invention vise à fournir un joint  universel qui a     l'avantage    de pouvoir transmettre un  mouvement de rotation à une vitesse beaucoup plus  élevée que les joints     universels    du type     cardan    dans  lesquels un croisillon à deux paires de tourillons     relie     les deux pièces rotatives. Ce joint universel a en  outre l'avantage d'être     susceptible    d'être fabriqué en  grande série à un prix de revient peu élevé. De tels  joints sont employés en     particulier        dans    l'industrie  de la machine-outil pour l'entraînement de broches  de perçage, de fraisage, de meulage, etc.  



  Le joint universel objet de l'invention est carac  térisé en ce que l'un de ses arbres se     termine    par une       partie    sphérique pivotant dans un logement pratiqué  dans l'extrémité de l'autre     arbre,    le couple de rota  tion étant transmis par au moins une     bille    logée par  tiellement dans la partie sphérique de l'arbre     mâle    et       partiellement    dans la paroi du logement de cette  partie sphérique.  



  Le     dessin    annexé représente à titre d'exemple  deux formes d'exécution du     joint.    La     fig.    1 est une  vue comprenant une coupe     partielle    de la première  forme d'exécution d'un joint universel dont le che  min de roulement des billes est prévu dans la partie  sphérique de l'arbre     mâle.     



  La     fig.    2 est une coupe suivant la ligne A-A.  La     fig.    3 est une vue     comprenant    une coupe par  tielle d'un     joint    universel selon une deuxième     forme     d'exécution dont le     chemin    de roulement des billes  est prévu dans la paroi de l'arbre femelle.    Les     fig.    1 et 2 représentent une première forme  d'exécution du joint. Ce joint comporte un arbre 1  se     terminant    par une partie sphérique 2 ajustée dans  le logement 3 de l'arbre 4. Une spire de ressort 5  placée dans une gorge du logement 3 empêche la       partie    sphérique 2 de sortir de son logement 3.

   Une       bille    6 dont le centre     géométrique    se     trouve    placé  dans un plan     perpendiculaire    à l'axe de l'arbre 4  et passant par le centre géométrique de la partie  sphérique 2, est logée partiellement dans un alvéole  pratiqué dans la partie sphérique 2 et     partiellement          dans    un trou percé dans la paroi du logement 3.  Cette bille a pour fonction de     transmettre    le couple  entre les deux     arbres    1 et 4.

   Une seule bille a  été représentée dans le but de     faciliter    la compré  hension de ce dessin, mais on a la possibilité de  placer plusieurs billes dans le même plan et sur la  même circonférence de la partie sphérique. Une  douille 7 emmanchée à force empêche la bille 6 de       sortir    de son logement.  



  Les     fig.    3 et 4 représentent une deuxième     forme     d'exécution dans laquelle les billes 6 sont logées par  tiellement dans des trous percés dans la partie sphé  rique 2, les axes de ces trous se trouvant placés dans  un     plan    perpendiculaire à l'axe de l'arbre 1, et par  tiellement dans des rainures prévues dans la paroi  du logement 3. Une douille 8     emmanchée    à force,  maintient, d'une     part,    les     billes    6     dans    leur loge  ment et empêche, d'autre     part,    la     partie    sphérique 2  de     sortir    de son logement 3.



      Universal joint The object of the present invention is a universal joint intended to connect two shafts driven in rotation and the intersecting axes of which form an angle with respect to each other.



  The present invention aims to provide a universal joint which has the advantage of being able to transmit a rotational movement at a much higher speed than universal joints of the cardan type in which a cross with two pairs of journals connects the two rotating parts. This universal joint also has the advantage of being capable of being mass produced at a low cost price. Such seals are used in particular in the machine tool industry for driving spindles for drilling, milling, grinding, etc.



  The universal joint which is the subject of the invention is characterized in that one of its shafts ends in a spherical part pivoting in a housing formed in the end of the other shaft, the torque being transmitted by the at least one ball housed partially in the spherical part of the male shaft and partially in the wall of the housing of this spherical part.



  The accompanying drawing shows by way of example two embodiments of the seal. Fig. 1 is a view comprising a partial section of the first embodiment of a universal joint of which the race min of the balls is provided in the spherical part of the male shaft.



  Fig. 2 is a section along line A-A. Fig. 3 is a view comprising a partial section of a universal joint according to a second embodiment of which the ball raceway is provided in the wall of the female shaft. Figs. 1 and 2 show a first embodiment of the seal. This seal comprises a shaft 1 ending in a spherical part 2 fitted in the housing 3 of the shaft 4. A spring coil 5 placed in a groove of the housing 3 prevents the spherical part 2 from coming out of its housing 3.

   A ball 6, the geometric center of which is placed in a plane perpendicular to the axis of the shaft 4 and passing through the geometric center of the spherical part 2, is partially housed in a socket made in the spherical part 2 and partially in a hole drilled in the wall of the housing 3. The function of this ball is to transmit the torque between the two shafts 1 and 4.

   A single ball has been shown for the purpose of making this drawing easier to understand, but it is possible to place several balls in the same plane and on the same circumference of the spherical part. A force-fitted socket 7 prevents the ball 6 from coming out of its housing.



  Figs. 3 and 4 show a second embodiment in which the balls 6 are housed partially in holes drilled in the spherical part 2, the axes of these holes being placed in a plane perpendicular to the axis of the shaft 1, and partly in grooves provided in the wall of the housing 3. A bush 8 force-fitted, on the one hand, maintains the balls 6 in their housing and, on the other hand, prevents the spherical part 2 from get out of their accommodation 3.
