Abstract

The mechanism comprises a first rotating part (1) which is connected coaxially by a transmission arm (2) to a second rotating part (3) for the transmission of a torque from one part to the other. The transmission arm is connected to each rotating part near their periphery. The transmission arm is articulated in a ball joint (5,6) on a frame (4).

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

L'invention est du domaine des mécanismes de transmission de forces dans un système tournant. Elle a pour objet un dispositif mécanique pour modifier, c'est à dire accroître ou inversement réduire, la force, ou couple, transmis par un premier organe tournant à un second organe tournant.  The invention is in the field of force transmission mechanisms in a rotating system. It relates to a mechanical device for modifying, that is to say increasing or conversely reducing, the force, or torque, transmitted by a first rotating member to a second rotating member.

On rappelle qu'un dispositif à levier est principalement constitué dans son principe par un bras supporté entre ses extrémités de manière pivotante sur un support d'appui. En faisant varier les distances complémentaires entre le support d'appui et l'une et l'autre des extrémités du bras, on fait varier l'ampleur de la force de réaction à l'une des extrémités du bras, à partir d'une force initiale appliquée à l'autre de ses extrémités.  It is recalled that a lever device is mainly constituted in principle by an arm supported between its ends in a pivoting manner on a support support. By varying the complementary distances between the support support and both ends of the arm, the magnitude of the reaction force is varied at one end of the arm, starting from a initial force applied to the other of its ends.

Le but de la présente invention est de proposer une application à un mécanisme tournant d'un dispositif à levier.  The object of the present invention is to propose an application to a rotating mechanism of a lever device.

La présente invention va être décrite en relation avec la figure unique de la planche annexée, qui illustre schématiquement un mécanisme selon un exemple de réalisation de l'invention.  The present invention will be described in relation to the single figure of the appended plate, which schematically illustrates a mechanism according to an exemplary embodiment of the invention.

Sur la figure, un mécanisme tournant comprend un premier organe tournant 1, qui est coaxialement relié par au moins un bras de transmission 2 à un deuxième organe tournant 3. Ce bras de transmission 2 est articulé en rotation sur un bâti 4 autour d'un axe A coaxial aux organes tournant 1 et 3, en vue de la transmission d'un couple de l'un à l'autre de ces organes 1 et 3.  In the figure, a rotating mechanism comprises a first rotating member 1, which is coaxially connected by at least one transmission arm 2 to a second rotating member 3. This transmission arm 2 is articulated in rotation on a frame 4 around a axis A coaxial with the rotating members 1 and 3, for the transmission of a torque from one to the other of these members 1 and 3.

Selon la présente invention, le bras de transmission 2 est relié à chacun des organes tournant 1 et 3 au voisinage de leur périphérie. Ces liaisons sont symétriquement inversées de l'un à l'autre des organes tournant 1 et 3 par rapport à l'articulation du bras de transmission 2 sur le bâti 4. Le bras de transmission 2 est articulé en rotule sur le bâti 4.  According to the present invention, the transmission arm 2 is connected to each of the rotating members 1 and 3 in the vicinity of their periphery. These connections are symmetrically reversed from one to the other of the rotating members 1 and 3 with respect to the articulation of the transmission arm 2 on the frame 4. The transmission arm 2 is articulated as a ball joint on the frame 4.

L'articulation en rotule du bras de transmission 2 comprend plus particulièrement sur l'exemple illustré une sphère 5 traversée par le bras de transmission 2. Cette sphère 5 est montée tournante à l'intérieur d'une coquille 6 du bâti 4.  The ball joint of the transmission arm 2 more particularly comprises, in the example illustrated, a sphere 5 crossed by the transmission arm 2. This sphere 5 is rotatably mounted inside a shell 6 of the frame 4.

<Desc/Clms Page number 2> <Desc / Clms Page number 2>

La sphère 5 est notamment montée mobile en translation (flèche 7) le long du bras de transmission 2, en étant immobilisable à une quelconque position sur celui-ci par des moyens de fixation. Ces dispositions sont telles que l'utilisateur puisse faire varier les distances complémentaires d1 et d2 entre l'articulation en rotule 5,6 et l'un et l'autre des organes tournant 1 et 3.  The sphere 5 is notably mounted movable in translation (arrow 7) along the transmission arm 2, being immobilizable at any position thereon by fixing means. These arrangements are such that the user can vary the complementary distances d1 and d2 between the ball joint 5,6 and both of the rotating members 1 and 3.

Selon diverses variantes, les organes tournant 1 et 3 sont, indépendamment l'un de l'autre, l'un quelconque des organes tournant du groupe de ceux comprenant les roues lisses, les roues dentées, les manivelles ou analogues. According to various variants, the rotating members 1 and 3 are, independently of one another, any one of the rotating members of the group of those comprising smooth wheels, toothed wheels, cranks or the like.
