Abstract (en)
[origin: EP1564372A1] The device has housings arranged in a rim (18), and balance weights (30, 40) placed in the housings. The housings are situated under a platform (32) that supports blades (20). A spring retaining ring is laterally positioned against the rim in order to partially close openings of the housings. The housings include cavities whose openings lead to respective sides of the rim. An intermediate channel connects the cavities. An independent claim is also included for a rotor including a disk and a disk balancing device.
