Abstract

Angular transmission with two incorporated ratios, with concurrent gears, with gear change during operation or when stopped. The apparatus is designed so that it allows a change from one ratio to the other without a risk of mechanical failure. It consists of a casing 22 supporting a bearing 23 in which there is introduced a driveshaft securely fastened to the pinions 4 and 5. An output shaft 21 supports two idle pinions 6 and 7 which mesh with 4 and 5. When the user gives the information to one of the two single-disc clutches 13 or 16 this clutch secures the pinion 7 or 6 with the shaft 21. The appliance according to the invention is particularly intended for mechanical transmissions in industry.

Description

La pressente invention un renvoi d'angle à deux rapports incorporés, à changement de vitesse en marche par embrayage, figure 1, feuille 1/3, ou X commande manuelle avec crabotage interne, figure 4, feuill 3/3. The present invention a bevel gear with two incorporated reports, gear change in operation by clutch, Figure 1, sheet 1/3, or X manual control with internal clutch, Figure 4, sheet 3/3.

L'originalité de ce matériel de transmission mécanique est d'introduire un deuxième trait d'engrenage concourant, permettant de sélectionner, par exemple, un rapport 1, ou un rapport rCducteur 2. The originality of this mechanical transmission material is to introduce a second concurrent gear line, making it possible to select, for example, a ratio 1, or a reduction ratio 2.

Un moteur entraide l'arbre (1) qui est maintenu par deux roulements (2) (3) servant de palier. Chacun des deux pignons coniques menants (4 et 5) étant solidaires de l'arbre (1). A motor supports the shaft (1) which is held by two bearings (2) (3) serving as a bearing. Each of the two driving bevel gears (4 and 5) being integral with the shaft (1).

Les pignons menants entraînent simultanément les pignons menus (6 et 7) montés pou sur roulements (8) et (9 et 10). The driving pinions simultaneously drive the small pinions (6 and 7) mounted for bearings (8) and (9 and 10).

Tant que l'une ies deux bobines de l'embrayage monodisque (16 et 13) n'est pas mis sous tension l'aupareil est au point mort. As long as one of the two coils of the single-plate clutch (16 and 13) is not energized, the device is in neutral.

,ise sous tension de l'embrayage (16), la bobine provoque un flux magnétique attirant l'arnture (14) sur le roter (15), comme le rotor est fix sur l'arbre (21), celui-ci tourne également, nous obtenons la première vitesse rap- port 1). , ise under tension of the clutch (16), the coil causes a magnetic flux attracting the lock (14) on the roter (15), as the rotor is fixed on the shaft (21), this one also turns , we get the first gear ratio 1).

Lorsque la tension de l'embrayage (16) est supprimé et qu'elle passe d-ns la bobine de l'embrayage (13) qui est fixé sur le flasque (18), il se produit éma- lement are attraction de l'armature (11) sur le rotor (í2) entrainint à son tour l'arbre (21) à une vitesse reduite (rapport 2). When the tension of the clutch (16) is removed and that it goes through the clutch coil (13) which is fixed on the flange (18), it also occurs are attraction of the armature (11) on the rotor (í2) in turn drives the shaft (21) at a reduced speed (ratio 2).

L'ensemble des pièces formant le carter (22) est réalisé par le palier (23) et les flasques (17 et 18), les roulements (19 et 20) sont le support de l'arbre (21). All the parts forming the casing (22) are produced by the bearing (23) and the flanges (17 and 18), the bearings (19 and 20) are the support of the shaft (21).

Les dessins. figure 2, feuille 2/3, représente la vue de gauche extérieure, la fixation du carter est réalisée par quatre trous taraudés sur chaque face de fixation. Le carter ayant pour dimension 200 mm de h-uteur et de largeur, et 270 mm de longueur. La figure 3, feuille 3/3, représente schématiquement l'appareil avec une inversion des sens de rotation suivant le rapport. (alors que dans la figure 1, le sens de rotation est identique quel que soit le rapport. The drawings. Figure 2, sheet 2/3, shows the outside view from the left, the housing is fixed by four tapped holes on each fixing face. The housing having a dimension of 200 mm in height and width, and 270 mm in length. Figure 3, sheet 3/3, schematically shows the apparatus with an inversion of the directions of rotation according to the ratio. (whereas in figure 1, the direction of rotation is identical whatever the ratio.

lie crabotage est également réalisable avec un sens de rotation identique sur l'or-
bre de sortie.The dog clutch is also achievable with an identical direction of rotation on the
exit bre.

Dans le dessin de la figure 1, le montage est réalisable avec des bagues en bronze en remplacement des roulements 8, 9, 10. In the drawing of FIG. 1, the assembly can be carried out with bronze rings to replace the bearings 8, 9, 10.

Caractéristiques techniques : l'appareil est dimensionné en fonction de la puissance à transmettre, les engrenages sont en acier de cémentation à denture droite ou hélicoidale. leur lubrification interne est réalisé par barbotage dans l'huile. Cinq bagues d'étanchéité assurent la retenue de l'huile. Rendement de l'zp- pareil environ 98%, la durée de vie théorique des pignons et ronlements sera de 15000 heures. La dissipation calorifique sera réalisée par le carter en fonte, les embrayages sont du type monodisque à sec, maintenus sur le carter par des flasques, repère 17 et 18 en aluminium, pour éviter la rémanence des embrayages, les flasques sont fixées sur le carter par huit vis. Toutes les positions de travail dans l'es- pace sont envisageables. Technical characteristics: the device is sized according to the power to be transmitted, the gears are made of case-hardening steel with straight or helical teeth. their internal lubrication is achieved by bubbling in the oil. Five sealing rings retain the oil. Yield of the zp- like around 98%, the theoretical lifespan of the pinions and hums will be 15000 hours. The heat dissipation will be carried out by the cast iron casing, the clutches are of the dry single plate type, held on the casing by flanges, mark 17 and 18 in aluminum, to avoid the persistence of the clutches, the flanges are fixed on the casing by eight screws. All working positions in the space are possible.

Applications industrielles : adaptable sur tout matériel de transmission industriel et matériel agricole (où il existe une boîte de vitesse pour certaines applications) Industrial applications: adaptable to all industrial transmission equipment and agricultural equipment (where there is a gearbox for certain applications)
