A work-assembling auxiliary device for carrying out the matching of phases in the spline-coupling of a main shaft Sm of a transmission T to a crankshaft Sc of an engine E includes an output shaft 40 radially movably connected through an Oldham coupling 41 to an input shaft 30 connected to and rotated by a drive source. A chamfer 61a is provided at a tip end of a socket 61 mounted on the output shaft 40, and in inserting the socket 61 into a socket hole h in a crank pulley Pc, the output shaft 40 is smoothly aligned with the crankshaft Sc by the action of the chamfer 61a. Further, when the output shaft 40 is reciprocally rotated, the phases of the socket 61 and the socket hole h are smoothly matched with each other, whereby the engagement of the socket 61 and the socket hole h is achieved. Thus, even if a somewhat deviation exists between an axis of the crankshaft Sc of the engine E and an axis of the output shaft 40 of the work-assembling auxiliary device, the socket 61 of the output shaft 40 can be reliably engaged into the socket hole h in the crankshaft Sc.

Appareil d'assemblage auxiliaire utilisé à des fins de synchronisation des phases de l'accouplement cannelé du vilebrequin (Sc) d'un moteur (E) et d'un arbre principal (Sm) d'une transmission (T). Il comprend un arbre de sortie (40), couplé radialement de façon mobile au moyen d'un joint d'Oldham (41) à un arbre d'entrée (30) relié rotatif à une source d'entraînement. L'arbre de sortie (40) est muni d'un manchon (61) ayant une extrémité chanfreinée (61a) qui aide l'arbre de sortie (40) à s'aligner sans à-coups sur le vilebrequin (Sc) lorsque le manchon (61) est inséré dans le trou du manchon (H) de la poulie (Sc). Lorsque l'arbre de sortie (40) pivote vers l'avant / vers l'arrière, les phases du manchon (61) et du trou du manchon (H) se mettent en correspondance, et le manchon (61) rentre dans le trou du manchon (H). Par conséquent, le manchon (61) de l'arbre de sortie (40) peut rentrer de façon sure dans le trou (H) du vilebrequin (Sc), même si l'axe du vilebrequin (Sc) du moteur (E) est légèrement décalé par rapport à l'axe de l'arbre de sortie (40)
