FIELD: machine building.SUBSTANCE: rotor section for turbomachine rotor includes fixing slots for rotating blades, which are provided on outside perimetre and spread in axial direction of the rotor. In each of the fixing slots there installed is one rotating blade with the blade root corresponding to the fixing slot for the rotating blade. Rotor section for the turbomachine rotor includes contact surfaces provided on rotating blades and facing radially inwards. In order to pass a cooling agent along end surface of the rotor, plate-like sealing elements adjoin the contact surface under action of centrifugal force. In order to fix sealing elements against being displaced in a circumferential direction, at least one of the sealing elements is equipped with a hole provided in that sealing element and serving for housing of a locking element. Besides, a seat coaxial to the hole and a locking element installed in the seat and in the hole with fixed position is provided. The seat is located at the blade root. The hole is made like a lock hole. The locking element is made in the form of a pin with a cam located on its outside perimetre, which can be screwed-in between the blade root and the sealing element.EFFECT: easier erection and removal of sealing elements.15 cl, 9 dwg |
