Abstract

Said two-for-one twisting spindle comprises the feature that it has a spindle foot 1 made of a synthetic resin, especially a thermoplastic resin obtained by moulding. A metal strengthening ring 9 has been incorporated in the resin of the spindle foot, this ring being placed at the bearing 4 supporting the axial load and the radial thrust due to the drive belt 6 and to residual eccentricity. A metal sleeve 5 is set at the base of the spindle foot to guide the rotating shaft 3. A space 11 has been left between the spindle foot 1 and the rotating shaft 3 to hold the lubricating oil, and axial holes or grooves in said metal sleeve 5 to allow the oil to pass into a second space 12 at the base of said spindle foot.

Description

La présente invention a pour objet une broche à double torsion pour fils, caractérisée en ce que le pied de broche est réalisé en résines synthétiques0
Selon une forme de réalisation préférée, lesdites résines synthétiques sont des résines thermoplastiques obtenues par moulage.The subject of the present invention is a double twist spindle for wires, characterized in that the spindle base is made of synthetic resins
According to a preferred embodiment, said synthetic resins are thermoplastic resins obtained by molding.

La broche en question se différencie donc sensiblement des broches connues dans lesquelles le pied de broche est réalisé en matière métallique0
Les avantages de la broche en question par rapport aux broches connues consistent dans la rapidité de production et par suite dans le faible coût et surtout dans l'adaptabilité immédiate de la partie en résine synthétique aux exigences diverses.The spindle in question therefore differs significantly from the known spindles in which the spindle base is made of metallic material.
The advantages of the spindle in question compared to known spindles consist in the speed of production and consequently in the low cost and especially in the immediate adaptability of the synthetic resin part to various requirements.

Le dessin annexé représente en coupe axiale une forme d'exécution préférée non limitative de la broche en question. The accompanying drawing shows in axial section a preferred non-limiting embodiment of the spindle in question.

La-broche comprend : le pied de broche 1 réalisé en résines synthétiques, de préférence en résines thermoplastiques, obtenues par moulage. The spindle comprises: the spindle base 1 made of synthetic resins, preferably of thermoplastic resins, obtained by molding.

La partie tournante 2, c'est-à-dire la poulie de la broche, entraînée par la courroie 6 est solidaire de l'arbre tournant 3. The rotating part 2, that is to say the pulley of the spindle, driven by the belt 6 is integral with the rotating shaft 3.

Un palier, de préférence un palier à billes 4, est interposé entre le pied de broche en résine synthétique 1 et l'arbre tournant 3 et sert à supporter la charge axiale ainsi que la poussée radiale due à la courroie de transmission 6 de la poulie d'entrainement 2 de la broche et à l'excentricité résiduelle. En fait, en maintenant entre certaines limites le déséquilibre résiduel de la broche à double torsion, ce déséquilibre reste pratiquement constant dans le temps parce que la bobine 8 du fil à retordre ou à cibler placé à 17inté- rieur de la broche ne tourne pas ; en outre, la façon de supporter la charge et de permettre la rotation exposée cidessus entraine un développement minimal de chaleur qui se dissipe aisément même si le support 1 est en matière plastique. A bearing, preferably a ball bearing 4, is interposed between the synthetic resin spindle foot 1 and the rotating shaft 3 and serves to support the axial load as well as the radial thrust due to the transmission belt 6 of the pulley drive 2 of the spindle and the residual eccentricity. In fact, by keeping the residual imbalance of the double twist spindle between certain limits, this imbalance remains practically constant over time because the coil 8 of the twist or target yarn placed inside the spindle does not rotate; in addition, the manner of supporting the load and allowing the rotation exposed above leads to a minimal development of heat which dissipates easily even if the support 1 is made of plastic.

Tout cela permet d'établir le pied de broche 1 en matière plastique et non plus en métal, le siège du palier pouvant être renforcé par un anneau métallique 9 avec aussi insertion d'une douille inférieure en létal 5 pour guider l'arbre de la broche à sa base. All this makes it possible to establish the spindle base 1 made of plastic and no longer of metal, the bearing seat being able to be reinforced by a metal ring 9 with also the insertion of a lower lethal bush 5 to guide the shaft of the brooch at its base.

Un intervalle Il qui agit comte logement d'huile lubrifiante est ménagé entre ledit pied de broche et l'arbre tournant 3. An interval II which acts as a housing for lubricating oil is formed between said spindle base and the rotating shaft 3.

La douille en métal 5 à la base de l'arbre tournant 3 s'insère directement dans la résine du pied de broche I ou indirectement par l'intermédiaire de la chemise cannelée ou percée axialement 10. The metal socket 5 at the base of the rotating shaft 3 is inserted directly into the resin of the spindle foot I or indirectly via the grooved or axially drilled sleeve 10.

Le cannelage ou l'alésage axial de la chemise 10 ou de la douille 5 servent à laisser passer l'huile lubrifiante de l'intervalle Il à l'espace 12 situé à la base du pied de broche 1. The grooving or the axial bore of the jacket 10 or of the sleeve 5 serves to let the lubricating oil pass from the interval II to the space 12 situated at the base of the spindle foot 1.

On a prévu que la douille en nétal 5 peut être autolubrifiante et peut être remplacée par un second palier à billes ou à rouleaux ; ces paliers pourraient aussi etre lubri- fiés par de la graisse au lieu d'huile,
La forme des diverses parties de la broche en question pourrait varier sans s'écarter du dosaine de protection de l'invention. Provision has been made for the metal bush 5 to be self-lubricating and can be replaced by a second ball or roller bearing; these bearings could also be lubricated with grease instead of oil,
The shape of the various parts of the spindle in question could vary without departing from the protective spade of the invention.
