УСТРОЙСТВО ПОЗИЦИОНИРОВАНИЯ ЛОПАТКИ И ДИСК С ЛОПАТКАМИ, СОДЕРЖАЩИЙ ТАКОЕ УСТРОЙСТВО

摘要

The device has a spacer (7) sliding between a root of a blade and a base of a slot provided on periphery of a disk of a rotor. The spacer presents a hollow profiled shape and comprises two lateral walls (12a, 12b) connecting a top wall (10) and a bottom wall (11). The spacer deforms during installation in order to generate a radial spring force which presses the root against bearing surfaces of the disk. An independent claim is also included for a bladed disk comprising a positioning device.
