Title (EN) STRUCTURE FOR CENTERING BETWEEN MACHINE SHAFT AND MOTOR SHAFT
(FR) STRUCTURE POUR CENTRAGE ENTRE UN ARBRE MACHINE ET UN ARBRE MOTEUR
Abstract:
(EN) On the under face of a first fitting plate (4), an annular projection (6) is formed around a central through hole (5), and the outer circumferential wall (61) of the projection (6) is finished to a complete roundness. When a motor (2) is fitted to the first fitting plate (4), the position of a motor shaft (3) is adjusted with reference to the round outer circumferential wall (61). On the other hand, the upper part of the inner circumferential wall of a second fitting plate (10) around the central through hole (5) is formed into an expanded diameter part (71), whose inner circumferential wall is finished to a complete roundness. When the housing (9) of a machine tool is fitted to the second fitting plate (10), the position of a main shaft (1) is adjusted with reference to this round inner circumferential wall. As the projection (6) of the first fitting plate (4) is fitted into the expanded diameter part (71) of the second fitting plate (10), the axial center of the motor shaft (3) and that of the main shaft (1) are aligned to each other.
(FR) Sur la face inférieure d'une première plaque de montage (4), une projection annulaire (6) est formée autour d'un trou traversant central (5), et la paroi du pourtour externe (61) de la projection (6) est finie en un arrondi complet. Lorsqu'un moteur (2) est monté sur la première plaque de montage (4), on règle la position d'un arbre moteur (3) par rapport à la paroi du pourtour externe (61). Par ailleurs, la partie supérieure de la paroi du pourtour interne d'une seconde plaque de montage (10) autour du trou traversant central (5) est formée en une partie à diamètre étendu (71) dont la paroi de pourtour interne est finie en un arrondi complet. Lorsque le boîtier (9) d'une machine-outil est monté sur la seconde plaque de montage (10), la position d'un arbre principal (1) est réglée par rapport à cette paroi de pourtour interne. Au moment où la projection (6) de la première plaque de montage (4) est montée dans la partie à diamètre étendu (71) de la seconde plaque de montage (10), l'arbre moteur (3) et l'arbre principal (1) sont en alignement axial central.
