Description

  

  Accouplement flexible         Uinvention    a pour objet un accouplement flexible  comprenant deux organes destinés<B>à</B> être attachés, res  pectivement<B>à</B> deux parties devant être accouplées et  un élément flexible entre les deux dits organes com  prenant des bras s'étendant     radialement   <B>à</B> partir d'une  partie centrale, ces deux organes comportant des     cra-          bots    venant en, prise avec ledit élément flexible.  



  Cet accouplement flexible est caractérisé en ce  que les bords des crabots adjacents aux bras de<B>l'élé-</B>  ment flexible sont concaves autour     d#axcs    transver  saux par rapport<B>à</B> l'axe de l'accouplement, en ce que  les bras<B>de</B> l'élément flexible ont chacun une forme  de tonneau en coupe transversale par rapport<B>à</B> l'axe  du bras pour s'adapter aux bords concaves des     cra-          bots,    au moins une partie desdits crabots étant amo  vibles et pouvant être fixés auxdits deux organes  après qu'ils ont été assemblés<B>à</B> l'élément flexible.  



  Une forme d'exécution préférée de l'accouplement  flexible selon l'invention et une variante vont être  décrites maintenant,<B>à</B> titre     d7exemple,    en référence  aux dessins ci-joints, dans lesquels:  La     fig.   <B>1</B> est une vue en coupe d'un accouplement  flexible suivant la ligne<B>1-1</B> de la     fig.   <B>5.</B>  



  La     fig.    2 est une vue semblable<B>à</B> celle de la       fig.   <B>1,</B> mais montrant une variante.  



  La     fig.   <B>3</B> montre l'un des organes extérieurs ou<B>à</B>  bride de la     fig.    2 avec les crabots amovibles fixés<B>à</B>  celui-ci.  



  La     fig.    4 est une autre vue<B>de</B> l'organe<B>à</B> bride de  la     fig.   <B>3,</B> vu dans la direction de la flèche<B>A,</B> et  la     fig.   <B>5</B> est une vue de bout<B>de</B> l'accouplement  de la     fig.   <B>1</B> lorsqu'il est assemblé.    Dans les exemples des     fig.   <B>1<I>à</I> 5,</B> les organes exté  rieurs sont deux organes circulaires<B>à</B> bride<B>1</B> et 2.  Des crabots amovibles uniformément espacés 4 sont  fixés aux brides<B>7</B> des organes<B>1,</B> 2 au moyen de vis  <B><I>5</I> à</B> têtes présentant une cavité polygonale.

   Le nombre  des crabots 4 est égal au nombre des espaces formés  entre les bras radiaux<B>11</B> de l'élément flexible<B>3,</B> qui  est en caoutchouc ou en matière analogue. Les crabots  fixés<B>à</B> l'organe<B>1</B> occupent les espaces entre ces bras  alternant avec les autres<B>de</B> ces espaces occupés par  les crabots fixés<B>à</B> l'organe 2.  



  Les organes<B>à</B> bride<B>1</B> et 2 sont pourvus chacun  d'une lèvre<B>6 à</B> la périphérie des faces sur lesquelles  les crabots 4 sont fixés afin de maintenir les crabots  en position. Des trous d'accès<B>8</B> permettant le passage  des vis<B>5 à</B> têtes présentant une cavité polygonale sont  ménagés dans chacun des, organes<B>à</B> bride<B>1,</B> 2 aux  endroits qui sont en regard des têtes de vis dans  l'autre organe<B>à</B> bride 2,<B>1.</B>  



  D'ans la variante montrée<B>à</B> la     fig.    2, les trous  d'accès,<B>8</B> sont omis dans l'organe<B>à</B> bride 2a, du  moment que cet organe porte une roue<B>à</B>     chdine   <B>9</B>  qui obstruerait de tels trous d'accès s'ils étaient pra  tiqués dans l'organe 2a. Des trous d'accès<B>8</B> sont per  cés dans l'autre, organe<B>à</B> bride la.  



  On voit qu'un certain nombre ou tous les crabots  peuvent être glissés en position et fixés en place après  que les organes<B>à</B> bride et l'élément flexible ont été  mis en position sur des, arbres<B>à</B> accoupler, ce qui  évite la nécessité de forcer les bras radiaux<B>11</B> en  forme de tonneau de l'élément flexible<B>3</B> par-dessus  les profils concaves<B>10</B> des crabots. Dans le cas de la  variante     (fig.    2), les crabots de l'organe<B>à</B> bride la  sont fixés<B>à</B> celui-ci avant que l'accouplement soit mis  en position sur les arbres et les crabots restants sont      glissés en place et fixés<B>à</B> l'organe<B>à</B> bride 2a après       rassemblage    du reste<B>de</B> l'accouplement.  



  Dans d'autres variantes, l'organe<B>à</B> bride 2a peut  porter une roue dentée ou une, poulie ou un autre  dispositif mécanique au lieu d'une roue<B>à</B> châtie. Les  vis<B>à</B> têtes présentant une cavité polygonale, peuvent  être remplacées par     Wimporte    quel     âutre    moyen de  fixation convenable. Un nombre différent de, crabots  avec un nombre différent correspondant     d#espaces     entre les bras de l'élément flexible peuvent être  prévus.



  Flexible coupling The invention relates to a flexible coupling comprising two members intended <B> to </B> to be attached, respectively <B> to </B> two parts to be coupled and a flexible element between the two said members comprising arms extending radially <B> to </B> from a central part, these two members comprising clogs coming into engagement with said flexible element.



  This flexible coupling is characterized in that the edges of the dogs adjacent to the arms of the flexible element are concave around axcs transverse to the <B> to </B> axis coupling, in that the arms <B> of </B> the flexible member are each barrel-shaped in cross-section with respect to <B> to </B> the axis of the arm to accommodate to the concave edges of the cogs, at least part of said dogs being removable and being able to be fixed to said two members after they have been assembled <B> to </B> the flexible element.



  A preferred embodiment of the flexible coupling according to the invention and a variant will now be described, <B> through </B> by way of example, with reference to the accompanying drawings, in which: FIG. <B> 1 </B> is a sectional view of a flexible coupling taken along the line <B> 1-1 </B> of fig. <B> 5. </B>



  Fig. 2 is a view similar <B> to </B> that of FIG. <B> 1, </B> but showing a variant.



  Fig. <B> 3 </B> shows one of the external members or <B> to </B> flange of fig. 2 with the removable dogs attached <B> to </B> this one.



  Fig. 4 is another view <B> of </B> the member <B> with </B> flange of FIG. <B> 3, </B> viewed in the direction of arrow <B> A, </B> and fig. <B> 5 </B> is an end view <B> of </B> the coupling of fig. <B> 1 </B> when assembled. In the examples of fig. <B> 1 <I> to </I> 5, </B> the external members are two circular members <B> with </B> flange <B> 1 </B> and 2. Uniformly removable dogs spaced apart 4 are fixed to the flanges <B> 7 </B> of the members <B> 1, </B> 2 by means of screws <B> <I> 5 </I> with </B> heads having a cavity polygonal.

   The number of dogs 4 is equal to the number of spaces formed between the radial arms <B> 11 </B> of the flexible element <B> 3, </B> which is made of rubber or a similar material. The dogs attached <B> to </B> the member <B> 1 </B> occupy the spaces between these arms alternating with the other <B> of </B> these spaces occupied by the attached dogs <B> to </B> organ 2.



  The members <B> with </B> flange <B> 1 </B> and 2 are each provided with a lip <B> 6 at </B> the periphery of the faces on which the dogs 4 are fixed in order to keep the dogs in position. Access holes <B> 8 </B> allowing the passage of the screws <B> 5 to </B> heads having a polygonal cavity are made in each of the members <B> to </B> flange <B > 1, </B> 2 at the places which are opposite the screw heads in the other member <B> to </B> flange 2, <B> 1. </B>



  In the variant shown <B> to </B> in fig. 2, the access holes, <B> 8 </B> are omitted in the <B> to </B> flange member 2a, as long as this member carries a <B> to </B> chdine wheel <B> 9 </B> which would obstruct such access holes if they were made in component 2a. Access holes <B> 8 </B> are drilled in the other, member <B> to </B> the flange.



  It can be seen that a number or all of the dogs can be slid into position and secured in place after the <B> flanged </B> members and the flexible element have been placed on shafts <B> to </B> couple, which avoids the need to force the barrel-shaped radial arms <B> 11 </B> of the flexible element <B> 3 </B> over the concave profiles <B > 10 </B> dogs. In the case of the variant (fig. 2), the dogs of the component <B> to </B> flange la are fixed <B> to </B> this one before the coupling is put in position on the remaining shafts and dogs are slid into place and secured <B> to </B> flange member 2a after assembling the remainder <B> of </B> the coupling.



  In other variants, the <B> to </B> flange member 2a may carry a toothed wheel or a pulley or other mechanical device instead of a <B> </B> wheel. The screws <B> with </B> heads having a polygonal cavity, can be replaced by any other suitable fixing means. A different number of dogs with a corresponding different number of spaces between the arms of the flexible element can be provided.
