Abstract

The protective cover for a power transmission shaft has an inverted U-section casing which has separate end walls to fit over the shaft. The half shell is mounted on the frame of the machine by the legs of the inverted U-shaped housing. The housing can have relief tracings perpendicular to its axis and spaced regularly to ease cutting to the required length.

Description

La présente invention concerne un dispositif pour assurer une protection intégrale contre les contacts du personnel avec les arbres de transmission puissance animés d'un mouvement de rotation ou linéaire, en conformité avec le décret 93J40. The present invention relates to a device for ensuring complete protection against personnel contact with power transmission shafts driven by a rotation or linear movement, in accordance with decree 93J40.

La protection des arbres n'est traditionnellement assurée niveau des accouplements que sur 270 radialement et, en laissant un accès axialement. Un contact inopiné peut avoir lieu en particulier avec les doigts. The protection of the shafts is traditionally ensured level of the couplings only on 270 radially and, leaving an access axially. Unintentional contact may occur in particular with the fingers.

Le dispositif, selon l'invention, permet de remédier à ces inconvénients. I1 comporte comme première caractéristique, d'être constitué d'une demi-coquille en forme de U inversé et de deux fonds aux extrémités, ouverts pour le passage des arbres, enfermant accouplement et arbres sur 360 radialement et, d'être adaptable en longueur de façon à protéger axialement l'arbre, de la sortie de l'arbre à la machine menante, sortie de l'arbre de la machine menée. fixation au sol est assurée par les retours horizontaux des branches des U. The device according to the invention overcomes these drawbacks. I1 has as a first characteristic, to be constituted by a half-shell in the shape of an inverted U and two bottoms at the ends, open for the passage of the shafts, enclosing coupling and shafts on 360 radially and, being adaptable in length so as to protect the shaft axially, from the output of the shaft to the driving machine, output of the shaft from the driven machine. fixing to the ground is ensured by the horizontal returns of the branches of the U.

Selon modes particuliers de réalisation - le réglage de la longueur est obtenu par la coupe d'une longueur nécessaire et suffisante du profil U. According to particular embodiments - the length adjustment is obtained by cutting a necessary and sufficient length of the U profile.

- le montage et le centrage du fond sur la pièce principale obtenu grâce à un emboîtement suivant détails figurant sur le plan et par collage ou fixation par des vis. - mounting and centering of the base on the main part obtained by interlocking according to details on the plan and by gluing or fixing with screws.

- la découpe à la longueur est facilitée par des tracés en relief, perpendiculaires à et espacés régulièrement. - cutting to length is facilitated by raised lines, perpendicular to and regularly spaced.

- l'ouverture sur le dispositif pour le passage des arbres peut être agrandie par découpe et, des rayures concentriques en relief faciliteront le travail d'adaptation. - The opening on the device for the passage of the trees can be enlarged by cutting and, concentric stripes in relief will facilitate the adaptation work.

Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.

La figure 1 représente une vue en perspective du profil et fonds. La figure 2 représente une vue en coupe du profil. Figure 1 shows a perspective view of the profile and backgrounds. Figure 2 shows a sectional view of the profile.

La figure 3 représente une vue de face et en coupe du fond. Figure 3 shows a front view and in section of the bottom.

En référence aux dessins, l'utilisateur coupe le profil (2) suivant la longueur nécessaire. II assemble par collage ou boulonnage les fonds (1) sur le profil. With reference to the drawings, the user cuts the profile (2) according to the necessary length. It assembles by gluing or bolting the bottoms (1) on the profile.

A titre d'exemples non limitatifs, les parties (1) et (2) assemblées auront des dimensions en coupe de l'ordre de 150x100, 235x150, 320x200, 405x250, 460x300 mm.By way of nonlimiting examples, the parts (1) and (2) assembled will have cross-sectional dimensions of the order of 150x100, 235x150, 320x200, 405x250, 460x300 mm.

Le dispositif sera réalisé en matière plastique thermoformé pour le profil et injecté dans des moules pour les fonds et produit en série. Il sera fourni en longueur de profil de 1 à 2 mètres pour être coupé et assemblé par les utilisateurs ou livré aux côtes prêt à ère monté. The device will be made of thermoformed plastic for the profile and injected into molds for the bottoms and mass produced. It will be supplied in profile length from 1 to 2 meters to be cut and assembled by users or delivered to the ribs ready for installation.
