Description

"Dispositif support de train de chenille amovible pour
engin agricole tel que moissonneuse-batteuse"
La présente invention concerne un dispositif support de train de chenille amovible pour engin agricole tel que moissonneuse-batteuse.
"Removable crawler undercarriage support for
agricultural machinery such as combine harvester "
The present invention relates to a removable crawler undercarriage support device for agricultural machinery such as a combine harvester.

I1 est courant de remplacer la roue d'un engin agricole tel que moissonneuse-batteuse ou autre, par des trains de chenilles pour permettre leur utilisation sur terrain très humide, ce qui est fréquemment le cas pour la récolte du mals qui se fait à l'automne, c'est-à-dire durant une période normalement très arrosée. It is common to replace the wheel of an agricultural machine such as a combine harvester or other, with crawler trains to allow their use on very wet ground, which is frequently the case for the harvest of the mals which is done in the 'autumn, that is to say during a period normally very wet.

A l'origine, les arbres de roues des moissonneuses-batteuses sortant axialement à l'essieu tubulaire permettaient un montage facile des trains de chenilles dont le bâti était fixé à l'essieu flottant et le barbotin ou pignon d'entraînement de la chenille était bridé à l'arbre.  Originally, the combine harvester shafts extending axially out of the tubular axle allowed easy assembly of the crawler tracks, the frame of which was fixed to the floating axle and the sprocket or pinion for driving the track was restrained to the tree.

Cependant, en raison des couples de torsion importants auxquels ils étaient soumis, les arbres cassaient fréquemment. However, due to the significant torques to which they were subjected, the trees frequently broke.

Pour y remédier, on a fabriqué des moissonneuses-batteuses avec un réducteur en bout d'arbre, sans palier flottant apparent. To remedy this, combine harvesters were manufactured with a shaft end reducer, with no apparent floating bearing.

L'invention a pour but de permettre un montage de trains de chenilles en sortie de réducteur, c'est-à-dire sur le flasque tournant constituant l'arbre de sortie du réducteur et sur lequel est normalement bridé l'arbre de roue. The object of the invention is to allow the mounting of crawler tracks at the output of the reducer, that is to say on the rotating flange constituting the output shaft of the reducer and on which the wheel shaft is normally clamped.

A cet effet, le dispositif support qu'elle concerne est du type comportant un barbotin ou pignon d'entraînement de la chenille bridé contre un flasque support, lui-même bridé à l'arbre de sortie du réducteur, les axes des galets de guidage de la chenille étant eux-mêmes supportés par un bâti. To this end, the support device that it relates to is of the type comprising a sprocket or pinion for driving the track clamped against a support flange, itself clamped to the output shaft of the reduction gear, the axes of the guide rollers. of the track being themselves supported by a frame.

Dans ce dispositif, à la face externe du flasque support du barbotin, est fixé, coaxialement, un arbre auxiliaire supportant; par l'intermédiaire d'au moins deux paliers, un moyeu dont l'extrémité la plus proche du flasque support du barbotin est bridée au flasque central du bâti du train de chenille. In this device, on the external face of the gypsy support flange, is fixed, coaxially, an auxiliary shaft supporting; by means of at least two bearings, a hub whose end closest to the gypsy support flange is clamped to the central flange of the frame of the crawler train.

De préférence, I'extrémité libre du moyeu supporté par l'arbre auxiliaire est fermé par un couvercle de protection fixé en bout de moyeu. Preferably, the free end of the hub supported by the auxiliary shaft is closed by a protective cover fixed at the end of the hub.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce disposi tif support
Figure 1 en est une vue en bout suivant la flèche A de figure 2;
Figure 2 en est une vue, à échelle agrandie, en coupe axiale de figure 1.
Anyway, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this support device.
Figure 1 is an end view along arrow A of Figure 2;
Figure 2 is a view, on an enlarged scale, in axial section of Figure 1.

Comme le montre le dessin, ce dispositif est du type comportant un flasque (2) supportant le barbotin (3) ou pignon d'entraînement de la chenille (4) et qui lui est bridé par des boulons (5). Ce flasque support (2) est destiné à etre fixé par bridage; au moyen de boulons (6), au flasque (7) constituant l'extrémité d'accouplement de l'arbre de sortie (8) du réducteur (9) situé en bout d'arbre d'une moissonneuse-batteuse, non représentée sur le dessin. As shown in the drawing, this device is of the type comprising a flange (2) supporting the gypsy (3) or drive pinion for the track (4) and which is clamped to it by bolts (5). This support flange (2) is intended to be fixed by clamping; by means of bolts (6), to the flange (7) constituting the coupling end of the output shaft (8) of the reducer (9) located at the end of the shaft of a combine harvester, not shown in the drawing.

Comme indiqué précédemment, l'essieu des moissonneuses-batteuses équipé de réducteurs en bout d'arbre n'est pas coaxial aux arbres de sortie des réducteurs, de sorte qu'il nVest pas possible d'utiliser cet essieu comme organe de support du bâti (11) supportant les axes des galets (25) de guidage de la chenille (4) constituant, ensemble, le train de chenille. As indicated above, the axle of combine harvesters fitted with shaft end reducers is not coaxial with the output shafts of the reducers, so it is not possible to use this axle as a support member for the frame (11) supporting the axes of the rollers (25) guiding the track (4) constituting, together, the undercarriage.

Selon l'invention, coaxialement au flasque (2) supportant le barbotin (3), est fixé, en saillie sur sa face externe, un arbre auxiliaire (12) supportant lui-même, par l'intermédiaire de deux paliers intérieur (13) et extérieur (14), un moyeu (15). Dans l'exemple illustré sur le dessin, l'arbre auxiliaire (12) est fixé au flasque (2) au moyen de deux cordons de soudure, respectivement (16) et (17). Le moyeu (15) estpw à son extrémité la plus proche du flasque (2), c'est-à-dire celle correspondant au palier (13), d'une collerette (18) qu;', dans cet exemple, lui est fixée par un cordon (19). Cette collerette est destinée à permettre le bridage du moyeu (15) au flasque central du bâti (11) à l'aide de boulons (21). According to the invention, coaxially with the flange (2) supporting the gypsy (3), is fixed, projecting on its external face, an auxiliary shaft (12) supporting itself, by means of two internal bearings (13) and outside (14), a hub (15). In the example illustrated in the drawing, the auxiliary shaft (12) is fixed to the flange (2) by means of two weld beads, respectively (16) and (17). The hub (15) is at its end closest to the flange (2), that is to say that corresponding to the bearing (13), of a flange (18) which, in this example, is fixed by a cord (19). This flange is intended to allow the clamping of the hub (15) to the central flange of the frame (11) using bolts (21).

Le moyeu (15) supporté par l'arbre auxiliaire (12) assure donc la tenue du bâti (11) du train de chenille, en remplacement de l'essieu de la moissonneuse-batteuse. The hub (15) supported by the auxiliary shaft (12) therefore ensures the holding of the frame (11) of the crawler train, replacing the axle of the combine harvester.

Les moyens d'immobilisation axiale des paliers (13 et 14) sont constitués, respectivement, par un épaulement (12a) de l'arbre (12) et (15a) de l'alésage du moyeu (15) pour le palier (13) et par un épaulement (12b) de l'arbre (12) et (15b) de l'alésage du moyeu (15) pour le palier (14), un écrou (22) vissé sur l'extrémité libre de l'arbre (12) pressant ia bague intérieure du palier (14) contre l'épaulement (12b) de l'ar- bre (12). The axial immobilization means of the bearings (13 and 14) are constituted, respectively, by a shoulder (12a) of the shaft (12) and (15a) of the bore of the hub (15) for the bearing (13) and by a shoulder (12b) of the shaft (12) and (15b) of the bore of the hub (15) for the bearing (14), a nut (22) screwed onto the free end of the shaft ( 12) pressing the inner ring of the bearing (14) against the shoulder (12b) of the shaft (12).

Pour protéger les paliers (13 et 14) qui, dans l'exemple illustré sur le dessin, sont constitués par des roulements à billes, l'extrémité
libre du moyeu (15) est fermée par un couvercle de protection (23)
qui lui est fixé par des vis (24).
To protect the bearings (13 and 14) which, in the example illustrated in the drawing, consist of ball bearings, the end
free from the hub (15) is closed by a protective cover (23)
which is fixed to it by screws (24).

Comme il va de soi et comme il ressort de ce qui précède,
l'invention ne se limite pas à la seule forme d'exécution décrite ci-dessus
à titre d'exemple non limitatif ; elle en embrasse, au contraire, toutes
les variantes de réalisation.
As is obvious and as is clear from the above,
the invention is not limited to the sole embodiment described above
by way of nonlimiting example; on the contrary, it embraces all
variant embodiments.
