Abstract
The invention concerns balancing devices for rotating mobile pieces, using alancing weights attached as necessary to one of several collars. Each balancing weight has a beak engaging a groove of a collar and is secured to the rotor by a suitable fastener, such as a rivet. Following balancing, a ring abutting against the grooved face of the collar is set in place. The ring is equipped with uniformly distributed recesses each intended to form a socket for a balancing weight and one of the ends of its fastener, so as to prevent the ejection of any of these elements in case of a failure of the means of fixation. The ring cooperates with the rotor in forming a chamber, to retain the other end of the fastener. The invention is applicable to the balancing of any rotating mobile piece and particularly to that of the rotors of axial compressors.
