Apparatus and method for locking blades into a rotor |
摘要 |
A blade is locked into groove in the periphery of a turbo-machine rotor by forming mating notches in opposing faces of the blade root and groove so as to form a blind hole. At assembly, a slotted radial pin is installed into the blind hole so as to prevent axial motion of the blade root. The pin is rotated so as to align its slot with a slot formed along the length of the rotor groove. A retaining strip is slid into the rotor groove slot so that it extends through the slot in the radial pin, with a pre-bent end of the strip resting against one face of the rotor. A tab formed on the other end of the strip is bent against another face of the rotor so as to lock the retaining strip in place. At dis-assembly, one of the retaining strip tabs is unbent and the retaining strip slid out. The pin is then extracted, thereby allowing the blade to be removed.
