  Réducteur de vitesse.

  
-Le but de cette invention est de réaliser, à l'aide de quatre pignons coniques,un réducteur de vitesse à rapport très élevé;
-A cet effet,un arbre coudé(N[deg.]3 et 4)soutient librement au moins <EMI ID=1.1> 

  
travaillant à la façon de satellites avec au moins deux plané-  taires concentriques(N[deg.]7 et 9)tous placés du même coté par rap-

  
 <EMI ID=2.1>  voque la rotation des satellites autour de leur axe commun(N[deg.]4) et le ou les autres trains la reçoivent en la diminuant à leur tour(N[deg.]8 et 9);
-A part un planétaire qui doit être fixé au carter,le nombre des autres trains planétaires est proportionnel au nombre de sorties ;
-La grandeur de réduction sera d'autant plus élevée que les rapports du diamètre primitif du planétaire fixe et du diamètre primitif de son satellite,ainsi que l'angle primitif de ce satellite et l'angle primitif de l'autre satellite considéré, sont de rapport réduit;
-Il est à remarquer que lorsque l'angle primitif du satellite en rapport avec le planétaire fixé au carter est plus petit que celui du satellite qu'il commande, le sens de rotation sera de sens contraire à celui d'entrée;il sera de même sens dans le  cas contraire;

  
-Pour les minipuissançes où il est possible d'employer des surfaces non dentées,ce qui permet de diminuer dans de fortes proportions les différences entre les diamètres primitifs ainsi que celles des angles primitifs considérées plus haut,l'on peut obtenir des grandeurs de rapport pratiquement illimitées.

  Speed reducer.

  
-The aim of this invention is to achieve, using four bevel gears, a very high ratio speed reducer;
-For this purpose, an angled shaft (N [deg.] 3 and 4) freely supports at least <EMI ID = 1.1>

  
working like satellites with at least two concentric planets (N [deg.] 7 and 9) all placed on the same side with respect to

  
 <EMI ID = 2.1> refers to the rotation of the satellites around their common axis (N [deg.] 4) and the other train (s) receive it by reducing it in turn (N [deg.] 8 and 9);
-Apart from a sun gear which must be fixed to the housing, the number of other planetary gears is proportional to the number of outputs;
-The reduction magnitude will be all the higher as the ratios of the pitch diameter of the fixed planetary gear and the pitch diameter of its satellite, as well as the pitch angle of this satellite and the pitch angle of the other satellite considered, are reduced ratio;
-It should be noted that when the pitch angle of the satellite in relation to the sun gear fixed to the housing is smaller than that of the satellite that it controls, the direction of rotation will be in the opposite direction to that of entry; it will be same meaning in the opposite case;

  
-For minipowers where it is possible to use non-toothed surfaces, which makes it possible to greatly reduce the differences between the pitch diameters as well as those of the pitch angles considered above, one can obtain ratio sizes practically unlimited.

7) Characterized in that it is possible to reverse the direction of rotation

  
 <EMI ID = 10.1>
