Abstract (en)
[origin: JPS6490047A] PURPOSE: To enable positioning cutter blades of a cutter head in a radial direction thereof by forming elongated holes having two parallel opposite internal longitudinal edges in respective cutter blades and engaging the internal edges with outer toothings at two parallel opposite external longitudinal edges of a shaft supporting disk. CONSTITUTION: One elongated hole 7 having two parallel opposite internal longitudinal edges for positioning a driving shaft 9 with a polygonal cross section is formed respectively in the cutter blades A to C arranged in a state balanced to each other with respect to the driving shaft 9. One row of inner toothing 10 is correspondingly provided at both parallel opposite internal longitudinal edges of the elongated hole 7 in order to engage with one row of outer toothing 11 respectively provided at two parallel opposite external longitudinal edges of the shaft supporting disk 8. Further, one hole is provided at the shaft supporting disk 8 in order to support the shaft 9 by a shape binding type, the size of the disk 8 in a direction of the outer toothing 11 is made smaller than the longitudinal extension of the elongated hole 7 and thickness thereof is made greater than depth of the elongated hole 7. Consequently, positioning of the cutter blades which is adjustable in a radial direction thereof and is of the shape binding type can be done.
