FIELD: turbine.
SUBSTANCE: turbine includes a turbine disc and other turbine parts, between which a cavity. Turbine disk includes first and second projections. First and second protrusions are formed, so that it is possible to secure the balance weight between the first projection and the second projection. First projection comprises a sealing section that is able to seal the passage of fluid between the turbine disks and other turbine part of the turbine. Cavity between the turbine disc and the other part of the turbine is limited radially inwardly of the sealing section and a radially outward another seal. In the manufacture of a turbine disk for a turbine having turbine disc and another turbine part, between which a cavity is formed first and second projections on the turbine disk. First and second protrusions are formed so that it is possible to secure the balancing weights there between. Cavity between the turbine disks and other turbine is often limited radially inward sealing section and a radially outward another seal.
EFFECT: group of inventions to simplify the manufacture of turbine disc having a balancing and sealing system.
