Abstract
To damp or prevent vibrations, the rotor blades 2 of an axial flow steam turbine are laced together by straight tubular members 5 each with its longitudinal axis extending both axially and circumferentially relative to the rotor disc. One end of each lacing member 5 is plugged to prevent leakage and is fixed relative to the associated blade by a flare and a collar 8 brazed to the member, whilst the other end of the member is a clearance fit in an adjacent blade aperture 3. In a modification, Fig. 3 (not shown), both ends of member 5 are clearance fits in the respective blades. Figs. 2, 7 (not shown), illustrate modified fixings for the ends of members 5. The members may be in one row at a substantially constant radial distance from the rotor axis, Fig. 5 (not shown), or may form two rows, Fig. 6 (not shown). In a further modification, the longitudinal axis of each member 5 extends radially as well as axially and circumferentially. The members may, alternatively, be solid rods of stainless steel or titanium.
