Abstract
L'invention concerne une construction d'un organe flexible de transmission et l'organe flexible de transmission obtenu par ce procédé. Selon l'invention, un fil métallique de section généralement circulaire est enroulé de manière à former un ressort hélicoïdal dont au moins une partie est formée de spires disposées en contact latéral l'une avec l'autre, et une précharge compressive d'une valeur déterminée est appliquée à cette partie. L'organe flexible ainsi obtenu sert à constituer, entre autres, un accouplement de transmission par pignon et crémaillère 4, le profil extérieur de sa partie pré-comprimée formant, après avoir été introduit dans un manchon cylindrique 5, une crémaillère sur laquelle engrène, au travers de la fente 10, une roue dentée 7.The invention relates to a construction of a flexible transmission member and the flexible transmission member obtained by this method. According to the invention, a metal wire of generally circular section is wound so as to form a helical spring, at least part of which is formed of turns arranged in lateral contact with one another, and a compressive preload of a value determined is applied to this part. The flexible member thus obtained serves to constitute, among other things, a transmission coupling by pinion and rack 4, the outer profile of its pre-compressed part forming, after having been introduced into a cylindrical sleeve 5, a rack on which meshes, through the slot 10, a toothed wheel 7.
