ROTOR HOHER SCHLANKHEIT

摘要

The present invention relates to a rotor for gas or steam turbines having a disk (1), an outer cover (2) and a plurality of blades (3). The disk (1) defines the portion of less diameter of the rotor and has an inner surface configured to be coupled on a shaft (100) of the turbine or connected to an axially adjacent disk (1', 1"); an outer surface configured for housing a plurality of blades (3). The outer cover (2) defines the portion of greater diameter of the rotor. The blades (3) have a root (31) configured to be coupled on the disk (1) and a tip (32) opposite to the outer cover (2). Between these blades there is a plurality of blades (3) welded together at the tip (32) to form groups of blades (3a) and individual blades (3b) intercalated between groups of blades (3a).
