Description

  

  Roue d'engrenage    La présente invention concerne une roue  d'engrenage d'angle présentant des dents en  forme générale cylindrique, réparties sur la  périphérie d'un plateau circulaire, caractérisée  en ce que lesdites dents présentent,<B>à</B> leur ex  trémité, une partie de plus faible diamètre réu  nie<B>à</B> la partie de plus grand diamètre par une  surface<B>à</B> double courbure.  



  Une telle roue peut être obtenue<B>à</B> l'état  fini par moulage d'une matière plastique, telle  que du polystyrène par exemple. Son prix<B>de</B>  revient est par conséquent très bas, et cette  matière présente en outre l'avantage de ne pas  être corrodée par certains agents, comme c'est  le cas pour certains métaux. Dans la fabrica  tion des compteurs d'eau ou de gaz, par exem  ple, cette particularité revêt un grand intérêt.  



  Le dessin annexé montre,<B>à</B> titre d'exemple,  une forme d'exécution de l'objet de l'inven  tion.  



  Les     fig.   <B>1</B> et 2 montrent la première roue       (J'un    couple en plan-, et de profil avec coupe.  Les     fig.   <B>3</B> et 4 représentent, dans les mê  mes positions, la seconde roue du couple.  



  La     fig.   <B>5</B> est une vue en plan schématique  illustrant     Fenarènement.     



  <B>C</B>    Le couple représenté comprend deux roues  <B>1</B> et 2 formées chacune d'un plateau circulaire  <B>3,</B> 3a, présentant plusieurs dents de forme<B>gé-</B>  nérale cylindrique 4, 4a, disposées<B>à</B> la péri  phérie du plateau correspondant. Ces dents  présentent,<B>à</B> leur extrémité, une partie de plus  faible diamètre réunie<B>à</B> la partie de plus  grand diamètre par une surface<B>à</B> double cour  bure rejoignant tangentiellement les deux dites  parties, ce qui confère<B>à</B> la dent l'apparence  d'une bouteille. Cette forme particulière des  dents 4, 4a permet d'obtenir un engrènement,  les surfaces entrant en contact pouvant être  conjuguées. La     fig.   <B>5</B> illustre la position res  pective des dents en position de fonctionne  ment.<B>-</B>



  The present invention relates to an angle gear wheel having teeth of generally cylindrical shape, distributed over the periphery of a circular plate, characterized in that said teeth have, <B> to </B> their end, a portion of smaller diameter joined <B> to </B> the portion of larger diameter by a surface <B> with </B> double curvature.



  Such a wheel can be obtained <B> in </B> the finished state by molding a plastic material, such as polystyrene for example. Its cost is therefore very low, and this material also has the advantage of not being corroded by certain agents, as is the case with certain metals. In the manufacture of water or gas meters, for example, this feature is of great interest.



  The accompanying drawing shows, <B> to </B> by way of example, one embodiment of the object of the invention.



  Figs. <B> 1 </B> and 2 show the first wheel (I have a couple in plan-, and in profile with section. Figs. <B> 3 </B> and 4 represent, in the same positions, the second torque wheel.



  Fig. <B> 5 </B> is a schematic plan view illustrating the event.



  <B> C </B> The pair shown comprises two wheels <B> 1 </B> and 2 each formed of a circular plate <B> 3, </B> 3a, having several shaped teeth <B> general cylindrical 4, 4a, arranged <B> at </B> the periphery of the corresponding plate. These teeth have, <B> at </B> their end, a part of smaller diameter joined <B> to </B> the part of larger diameter by a surface <B> with </B> double curvature tangentially joining said two parts, which gives <B> to </B> the tooth the appearance of a bottle. This particular shape of the teeth 4, 4a makes it possible to obtain meshing, the surfaces coming into contact being able to be conjugated. Fig. <B> 5 </B> illustrates the respective position of the teeth in the working position. <B> - </B>
