FIELD: power engineering.
SUBSTANCE: invention relates to heat engineering and can be used in designing shanks of working blades of steam and gas turbines. Shanks of working blades of the T-shaped or the fork type are arranged with interference in the circumferential direction. On the surface of the contact between the shanks there is a slot occupying at least 70 % of the contact surface and with the depth of at least 0.15 mm.
EFFECT: invention enables 3…4 times decreasing the required mounting force to ensure guaranteed circumferential interference, as well as reducing the surface of fitting each shank and increasing the vibration reliability.
