DEVICE FOR FIXING AXIALLY POSITION OF MOVING BLADE USED FOR AXIAL FLOW TYPE COMPRESSOR OR TURBINE AND FOR ELIMINATING ROTOR UNBALANCE

摘要

PURPOSE: To simplify the fixing of an impeller of an axial direction on both sides and control of a roller unbalance, in a root of the impeller and a wheel rim especially without a special structure. ;CONSTITUTION: A filling material 5 mounted on a bottom part of a groove and a position fixing thin plate 6 are inserted into each recessed part T, a gap S between a root end and the filling material 5 which extends along the recessed part T is buried by the position fixing thin plate 6, both end parts protruded from the recessed part T is folded toward an end surface of the filling material 5, an end surface of a wheel disk 4, and an end surface of the root 2 of the impeller in a direction reverse to each other. The rotor unbalance is compensated by at least one filling material.;COPYRIGHT: (C)1995,JPO
