FIELD: mechanical engineering; turbines.
SUBSTANCE: proposed wheel has blades fitted in wheel disk thrusting against sealing ring. Sealing ring is arranged, together with disk ring bead pointed to longitudinal axis, between walls of U-shaped lock split ring. Through cut of lock split ring is made in form of slot with walls parallel to radial axis where detent is arranged, being secured by flat lock. Slot for detent is made in wall of U-shaped lock ring arranged between bead of disk and disk and it communicates with additional diagonal cut made in other wall opposite to said slot in direct projection of the latter. Detent is made in form of plate fitted in slot, one surface of plate being engaged with lock fitted between U-shaped lock ring and disk.
EFFECT: provision of reliable locking of blades in wheel of turbomachine of small sizes operating at high temperature and centrifugal loads.
