Description

Turbine et son procédé de fabrication. L'invention est relative aux turbines métal liques, et elle concerne plus spécialement, parce qu'en ce cas, son application offre un grand intérêt, mais non exclusivement, celles employées en ven tilation. Turbine and its manufacturing process. The invention relates to metal turbines, and it relates more specifically, because in this case, its application offers great interest, but not exclusively, those used in ventilation.

Son but principal est d'alléger et de faciliter la construction de ces turbines en les réalisant à partir d'un seul flan, alors que traditionnellement elles sont construites en deux parties : le fond proprement dit réalisé en général par découpage dans une tôle et se présentant sous la forme d'un disque, sur lequel est rapporté par un moyen approprié : soudage ou rivetage, une virole cylindrique obtenue par enroulage d'un flan rectangulaire portant sur sa périphérie des aubes découpées. Its main goal is to lighten and facilitate the construction of these turbines by making them from a single blank, while traditionally they are built in two parts: the bottom proper generally produced by cutting from a sheet and in the form of a disc, on which is attached by suitable means: welding or riveting, a cylindrical shell obtained by winding a rectangular blank bearing on its periphery cut blades.

La présente invention a pour objet un procédé de fabrication concernant les turbines métalliques, et plus particulièrement mais non exclusivement celles employées en ventilation. Il consiste à obtenir par formage en partant d'un seul flan, une cloche sur la paroi latérale de laquelle, des aubes sont découpées et formées. The present invention relates to a manufacturing process relating to metal turbines, and more particularly but not exclusively those used in ventilation. It consists in obtaining by forming, starting from a single blank, a bell on the side wall of which the blades are cut and formed.

L'invention sera de toute façon bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif, une turbine métallique de ventilation obtenue par le procédé objet de l'invention- Figure 1 est une vue du flan avant formage; Figure 2 est une vue en coupe de la cloche, après formage; Figure 3 est une vue de côté de la turbine terminée ; Figure 4 est une vue de face de la turbine terminée ; Après formage le flan représenté par la figure 1 se présente sous la forme d'une cloche 2 dont 3 représente le fond, 4 la paroi latérale et 5 un bord destiné à en assurer la rigidité. The invention will in any case be well understood, with the aid of the following description, with reference to the appended schematic drawing, showing by way of non-limiting example, a metal ventilation turbine obtained by the method which is the subject of the invention. - Figure 1 is a view of the blank before forming; Figure 2 is a sectional view of the bell, after forming; Figure 3 is a side view of the completed turbine; Figure 4 is a front view of the completed turbine; After forming, the blank shown in FIG. 1 is in the form of a bell 2, 3 of which represents the bottom, 4 the side wall and 5 an edge intended to ensure its rigidity.

Les aubes 6 sont obtenues par découpage et formage au cours d'une seconde opération. The blades 6 are obtained by cutting and forming during a second operation.

Un orifice 7 est découpé dans le fond 3 de faon à permettre la fixation de la turbine sur un moyen approprié d'entraînement. An orifice 7 is cut in the bottom 3 so as to allow the fixing of the turbine on a suitable drive means.

Comme il va de soi, et comme il ressort déjà de ce qui précède, l'invention ne se limite pas à ce type de turbine et à sa seule forme d'exécution qui ont été décrites ci-dessus à titre d'exemple ; elle en embrasse, au contraire, toutes les variantes, quels que soient notamment la forme, le nombre, la répartition et le sens des aubes.As goes without saying, and as it already emerges from the foregoing, the invention is not limited to this type of turbine and to its sole embodiment which have been described above by way of example; on the contrary, it embraces all the variants thereof, regardless of the shape, number, distribution and direction of the blades.
