Abstract
A system for the rapid balancing of revolving shafts, in particular, the revolving shaft of a gas turbine. The system comprises two mutually adjacent bores provided in the stator of the turbine, which can be closed by relevant plugs, and which are collimated on the screw-threaded bores of the rotor. The system also comprises a special rigid rod for elastically holding a screw-threaded balancing mass, and for causing it to rotate.
