摘要: The device has two ring segments (13) held in a circumferential score (11) provided one edge of the upper surface (8) rotor disk. These consist portion cylindrical band (17) on whose edges are collars (18, 19) unequal thickness. thicker collar (18) is placed between wall transverse (7) made projection (6) and (1). works conjunction with bottom (11). thinnest (19) leans against groove. end to leave them space corresponding width axial notch. By displacing score, brought opposite blade be changed. locking pins (21) which engage ends block position. Other types applications described.
