Description
La présente invention concerne un dispositif d’étanchéité totale autour d’un arbre oscillant en rotation alternative. Le domaine technique peut être celui des machines thermiques à cycle Stirling. Un autre domaine peut être celui de l’étanchéité totale d’une paroi traversée par un arbre animé d’un mouvement de rotation continue.The present invention relates to a total sealing device around an oscillating shaft in alternating rotation. The technical field may be that of Stirling cycle thermal machines. Another field can be that of the total sealing of a wall crossed by a shaft driven by a continuous rotation movement.
Etat de la technique antérieureState of the prior art
Premièrement, les brevets FR2539811 et FR2846374 portant sur les machines thermiques à cycle Stirling à pistons oscillants (pistons toriques pour le premier brevet et pistons prismatiques pour le second brevet) permettaient de réaliser une étanchéité totale via une chaussette de torsion disposée autour d’un axe animé d’un mouvement de rotation alternative. Cette chaussette de torsion était encombrante. Deuxièmement, l’étanchéité relative d’une paroi traversée par un arbre animé d’un mouvement de rotation continue était réalisée par un simple joint (torique ou à lèvre entre autres) ne garantissant pas une étanchéité totale ; un dispositif a été conçu pour réaliser cette étanchéité totale.Firstly, patents FR2539811 and FR2846374 relating to Stirling cycle thermal machines with oscillating pistons (ring pistons for the first patent and prismatic pistons for the second patent) made it possible to achieve total sealing via a torsion sock arranged around an axis animated by an alternating rotational movement. This twist sock was cumbersome. Secondly, the relative tightness of a wall through which a shaft moved in continuous rotation was achieved by a simple seal (o-ring or lip, among others) which did not guarantee total tightness; a device has been designed to achieve this total sealing.
Autour de l’arbre animé d’un mouvement de rotation alternative, plutôt que d’utiliser une chaussette de torsion, on va avoir recours à un disque de torsion. Dans le cadre de l’application aux machines thermiques à cycle de Stirling, chaque arbre relié à un piston oscillant est animé d’un mouvement de rotation alternative autour duquel le disque de torsion vient réaliser l’étanchéité totale. Une manivelle quadratique est nécessaire pour transformer le mouvement de rotation alternatif des pistons oscillants en mouvement de rotation continue de l’arbre. Dans l’application à la paroi totalement étanche, celle-ci doit laisser passer un flux d’énergie mécanique de rotation continue. Le passage intermédiaire par un/des arbre(s) animé(s) d’un mouvement de rotation alternative et autour du/des quel(s) est réalisée une étanchéité totale avec un disque de torsion s’effectue à chacune des deux extrémités de l’arbre animé d’un mouvement de rotation alternative. Premièrement, la transformation de mouvement de rotation continue à mouvement de rotation alternative se fait par l’intermédiaire d’une première manivelle quadratique. Deuxièmement, l’étanchéité totale est réalisée à l’aide d’un disque de torsion. Troisièmement, la transformation de mouvement de rotation alternative à mouvement de rotation continue se fait par l’intermédiaire d’une deuxième manivelle quadratique.Around the shaft animated by an alternating rotational movement, rather than using a torsion sock, we will use a torsion disc. As part of the application to Stirling cycle thermal machines, each shaft connected to an oscillating piston is driven by an alternating rotational movement around which the torsion disk comes to achieve total sealing. A quadratic crank is needed to transform the reciprocating rotational motion of the oscillating pistons into the continuous rotational motion of the shaft. In the application to the completely sealed wall, the latter must allow a flow of mechanical energy of continuous rotation to pass. The intermediate passage through one or more shaft(s) driven by an alternating rotational movement and around which(s) a total seal is made with a torsion disk is effected at each of the two ends of the shaft animated by an alternating rotational movement. First, the transformation from continuous rotational motion to alternating rotational motion is done via a first quadratic crank. Secondly, total sealing is achieved using a torsion disc. Thirdly, the transformation from reciprocating rotational movement to continuous rotational movement takes place via a second quadratic crank.

La deuxième manivelle quadratique est composée d’un levier (500), d’un maneton (25), d’une bielle (23), d’un maneton (21) et d’un demi-arbre (2). Le flux d’énergie mécanique circule ici du demi-arbre en rotation continue (1) vers le demi-arbre en rotation continue (2) en passant par l’arbre (101) en rotation alternative. Le flux peut être inversé.a half-shaft (1), a crankpin (11), a connecting rod (13), a crankpin (15) and a lever (800). The lever (800) is connected in rotation to the shaft (101) around which is arranged a seal (1020) called torsion disc. This same shaft (101) is connected in rotation to the lever (500). The second quadratic crank is made up of a lever (500), a crankpin (25), a connecting rod (23), a crankpin (21) and a half-shaft (2). Here, the flow of mechanical energy flows from the continuously rotating half-shaft (1) to the continuously rotating half-shaft (2) via the reciprocating shaft (101). The flow can be reversed.
