Abstract
Description
La présente invention concerne un dispositif de comptage mécanique, de nombre de tours d'un axelpar par entrainement rotatif d'échappement d'un élément incline. The present invention relates to a mechanical counting device, number of revolutions of an axelpar by rotary exhaust drive of an inclined element.
Il existe actuellement sur le marché de tels dispositifs comprenant
- soit un pignon intermédiaire de démultiplication situé entre un axe menant denté et un axe mené, généralement en couronne ou roue dentée, supportant les inscriptions donnant une information sur la position de l'axe menant,
- soit un axe menant comportant un index excentré induisant un mouvement excentrique à une roue à denture extérieure. Cette dernière entrainant une roue à denture intérieure supportant les inscriptions donnant une information sur la position de l'axe menant.There are currently on the market such devices comprising
- either an intermediate reduction gear situated between a toothed driving axis and a driven axis, generally in a crown or toothed wheel, supporting the inscriptions giving information on the position of the driving axis,
- or a leading axis comprising an eccentric index inducing an eccentric movement to an external gear wheel. The latter driving an internal gear supporting the inscriptions giving information on the position of the driving axis.
Ces dispositifs présentent l'inconvénient de nécessiter la présence d'au moins trois pièces mobiles et pour le deuxième cas cité, un surdimensionnement radial dû au mouvement excentré. These devices have the disadvantage of requiring the presence of at least three moving parts and for the second case cited, a radial oversizing due to the eccentric movement.
L'objet de la présente invention permet d'obtenir le même résultat avec deux pièces mobiles et sans surdimensionnement. Un axe menant comportant extérieurement au minimum une dent engrenée avec une roue menée, dentée intérieurement sur toute sa circonférence et inclinée de 1 à 890. The object of the present invention makes it possible to obtain the same result with two moving parts and without oversizing. A driving axis having at least one tooth externally meshed with a driven wheel, toothed internally over its entire circumference and inclined from 1 to 890.
La roue menée est maintenue sur une pièce par clipsage ou accrochage. Le nombre de dents de la roue menante détermine un déplacement angulaire plus ou moins grand de la roue menée. The driven wheel is held on a part by clipping or hooking. The number of teeth of the driving wheel determines a more or less large angular displacement of the driven wheel.

L'axe menant (1) comporte une denture (3), sur une portion de sa périphérie, une dent au minimum, qui entraine directement une roue menée (2) dentée intérieurement sur toute sa circonférence inclinée de 1 à 890, par rapport à l'axe menant, supportant les inscriptions (5), qui affichent une information sur la position de l'axe menant.detailed description

- Plate 2/2 figure 2
The driving axis (1) has a toothing (3), on a portion of its periphery, at least one tooth, which directly drives a driven wheel (2) toothed internally over its entire circumference inclined from 1 to 890, relative to the driving axis, supporting the inscriptions (5), which display information on the position of the driving axis.
L'inclinaison de cette roue dentée permet son entrainement seulement pendant l'engrenage de la denture partielle de l'axe menant dans la denture de la roue menée. Le nombre de dents compris dans la portion dentée de l'axe menant permet de déterminer le déplacement angulaire de la roue menée.The inclination of this toothed wheel allows it to be driven only during the gearing of the partial toothing of the axis leading into the toothing of the driven wheel. The number of teeth included in the toothed portion of the driving axle makes it possible to determine the angular displacement of the driven wheel.
Après avoir obtenu le déplacement angulaire précédent, il est possible d'obtenir l'immobilisation de la roue menée, pendant la fin de la rotation de l'axe menant, par la présence, sur la roue menée de facettes d'immobilisation (6). Ceci nécessite une facette par fraction de tour durant laquelle la roue dentée (2) est immobilisée. After obtaining the previous angular displacement, it is possible to obtain the immobilization of the driven wheel, during the end of the rotation of the driving axle, by the presence, on the driven wheel of immobilization facets (6) . This requires a facet by fraction of a turn during which the toothed wheel (2) is immobilized.
L'immobilisation est réalisée par ltappui sur la facette, d'une piste lisse (7) qui succède à la denture partielle de l'axe menant (1). La roue dentée (2) est soutenue, par une pièce fixe (8).Immobilization is achieved by pressing on the facet, a smooth track (7) which succeeds to the partial toothing of the leading axis (1). The toothed wheel (2) is supported by a fixed part (8).
L'invention peut s'appliquer à toutes fonctions de comptage d'un nombre de rotation d'un axe, avec affichage du nombre de tours effectués. Exemple
- Boutons compte-tours : composant de face avant, fixé directement sur l'axe d'un composant tournant, le bouton compte-tours permet de compter le nombre de tours et fractions de tour. Par analogie la valeur affichée peut représenter toute grandeur physique choisie par l'utilisateur. La valeur affichée peut être exprimée par des chiffres, lettres, symboles, figures, code barres, réflecteurs optiques. The invention can be applied to all functions for counting a number of rotations of an axis, with display of the number of turns performed. Example
- Tachometer buttons: front panel component, fixed directly on the axis of a rotating component, the tachometer button allows you to count the number of revolutions and fractions of a revolution. By analogy, the displayed value can represent any physical quantity chosen by the user. The displayed value can be expressed by numbers, letters, symbols, figures, barcode, optical reflectors.
