Description

  

  Groupe électrogène hydraulique à axe vertical du type en parapluie.    La présente invention concerne un groupe  électrogène à turbine hydraulique à axe ver  tical, du type constructif dit en parapluie,  c'est-à-dire dans lesquels les parties rotatives  de la turbine et du générateur électrique sont  montées sur un arbre porté par un palier de  butée monté au-dessous de la machine supé  rieure et tournant dans deux paliers de gui  dage.  



  La présente invention permet de réaliser  d'importantes simplifications de construction  et d'exploitation de ces groupes électrogènes  par rapport aux réalisations connues et de  réduire par rapport à celles-ci l'encombrement  des groupes et, de ce fait, de réduire dans une  certaine mesure les travaux de génie civil né  cessaires pour les fondations et les bâtiments.  



  Le groupe électrogène selon l'invention se  distingue des groupes connus par le fait que  le palier de butée et le palier de guidage su  périeur sont portés par un support commun  reposant sur une bâche d'un distributeur de  la turbine et par le fait que le moyeu du  rotor du générateur électrique est assemblé  au cylindre d'un servomoteur de réglage de  la turbine, ce cylindre reposant par l'inter  médiaire d'un manchon sur le palier de butée.  



  Le dessin annexé montre schématiquement  et à titre d'exemple deux formes d'exécution  du groupe électrogène, objet de l'invention.  



  Le groupe électrogène représenté comporte  un alternateur 1 du type parapluie et une    turbine 2 du type Kaplan. La partie tournante  du groupe est guidée par deux paliers 3 et 4  et supportée par une butée 5.  



  Dans l'exemple de la     fig.1,    le palier de  guidage 4 de la machine supérieure,     c'est-          à-dire    de la génératrice électrique, prend appui  directement sur l'arbre. Ce palier de guidage  et la butée 5 sont portés par un support com  mun 6, solidaire du couvercle 7 qui repose  sur la bâche de distribution de la turbine.    Le manchon tournant 8 repose sur la par  tie tournante de la butée 5 et fait corps avec  le cylindre 9 du servomoteur Kaplan, et cette  pièce est prévue pour être accouplée, à sa  partie intérieure, à l'arbre 10 de la turbine,  par une bride circulaire 11 et à sa partie ex  térieure au moyeu 12 de l'alternateur, par la  bride 13.

   Le moyeu 12 de l'alternateur a une  forme appropriée à son accouplement à la  bride 13 et dans le but de rapprocher le plus  possible le centre de gravité du rotor de l'al  ternateur du plan d'action du palier de gui  dage 4, ce moyeu 12 entoure en grande partie  le palier de butée 5, ce qui conduit à un gain  important sur l'encombrement du groupe en  hauteur. Le cylindre 9 du servomoteur porte  à sa périphérie extérieure le collecteur à ba  gues 14 d'amenée de courant d'excitation au  rotor de l'alternateur.  



  Le support 6 du palier de butée sert égale  ment d'appui aux vérins de levage 1.5 atta-           quant    le rotor de l'alternateur par son moyeu  12.  



  L'alternateur 1 est     ainsi        libéré    de toute  charge importante. Il ne comporte ni croisil  lon     inférieur    ni consoles support de vérins, et  son     croisillon    supérieur 16 ne sert que de  plancher de fermeture et de support de la  tête de réglage Kaplan, non représentée sur la  figure. Le     croisillon    16 porte également les       vérins    de     freinage    17 attaquant le rotor de  haut en bas.  



  Dans la variante de la     fig.    2, le palier su  périeur de guidage 4' prend appui sur la par  tie tournante de cette butée.  



  Le manchon tournant 8 reposant sur la  partie tournante de la butée 5 fait corps,       comme    dans l'exemple de la     fig.1,    avec le cy  lindre 9 du     servo--moteur    Kaplan et est prévu  pour être accouplé, par la bride 11, à l'arbre  10 de la     turbine,    et par la bride 13, au moyeu  12 de l'alternateur;

       celui-ci    reste au-dessus du       palier    de butée 5, la réduction du groupe en  hauteur     qui,    dans le cas de la     fig.1,    provenait  de ce que le moyeu 12 entourait le palier de  butée 5, est ici     réalisée    du fait que c'est     sur     la partie     tournante    de cette butée 5 que prend  appui le     palier    de     guidage    4'.



  Umbrella type vertical axis hydraulic generator. The present invention relates to a hydraulic turbine generator set with a vertical axis, of the so-called umbrella constructive type, that is to say in which the rotating parts of the turbine and of the electric generator are mounted on a shaft carried by a bearing stopper mounted below the upper machine and rotating in two guide bearings.



  The present invention makes it possible to achieve significant simplifications in the construction and operation of these generator sets compared to known embodiments and to reduce the size of the groups in relation to them and, therefore, to reduce to a certain extent. measures the civil engineering work required for foundations and buildings.



  The generator set according to the invention differs from known groups by the fact that the thrust bearing and the upper guide bearing are carried by a common support resting on a cover of a distributor of the turbine and by the fact that the The hub of the rotor of the electric generator is assembled to the cylinder of a servomotor for adjusting the turbine, this cylinder resting by means of a sleeve on the thrust bearing.



  The appended drawing shows schematically and by way of example two embodiments of the generator set, object of the invention.



  The generator set shown comprises an alternator 1 of the umbrella type and a turbine 2 of the Kaplan type. The rotating part of the group is guided by two bearings 3 and 4 and supported by a stop 5.



  In the example of FIG. 1, the guide bearing 4 of the upper machine, that is to say of the electric generator, bears directly on the shaft. This guide bearing and the stop 5 are carried by a common support 6, integral with the cover 7 which rests on the distribution cover of the turbine. The rotating sleeve 8 rests on the rotating part of the stop 5 and is integral with the cylinder 9 of the Kaplan servomotor, and this part is intended to be coupled, at its inner part, to the shaft 10 of the turbine, by a circular flange 11 and on its part outside the hub 12 of the alternator, by flange 13.

   The hub 12 of the alternator has a shape suitable for its coupling to the flange 13 and with the aim of bringing the center of gravity of the rotor of the alternator as close as possible to the action plane of the guide bearing 4, this hub 12 largely surrounds the thrust bearing 5, which leads to a significant saving in the overall height of the group. The cylinder 9 of the booster carries at its outer periphery the ba ged collector 14 for supplying the excitation current to the rotor of the alternator.



  The support 6 of the thrust bearing also serves as a support for the lifting cylinders 1.5 attaching the rotor of the alternator by its hub 12.



  The alternator 1 is thus freed from any significant load. It has neither lower cross lon nor jack support consoles, and its upper cross member 16 only serves as a closing floor and support for the Kaplan adjustment head, not shown in the figure. The spider 16 also carries the brake cylinders 17 attacking the rotor from top to bottom.



  In the variant of FIG. 2, the upper guide bearing 4 'bears on the rotating part of this stop.



  The rotating sleeve 8 resting on the rotating part of the stop 5 is integral, as in the example of fig. 1, with the cylinder 9 of the Kaplan servo motor and is intended to be coupled, by the flange 11, to the shaft 10 of the turbine, and by the flange 13, to the hub 12 of the alternator;

       this remains above the thrust bearing 5, the reduction of the group in height which, in the case of fig. 1, was due to the hub 12 surrounding the thrust bearing 5, is here achieved because it is on the rotating part of this stop 5 that the guide bearing 4 'rests.
