In order to form the string of the gas turbine null bucket which possesses the plate for lock

摘要

The turbine disk (36) the many cooling possible bucket (12) it has on, each bucket, in axis direction of the turbine disk extending the bucket containment slot which is present (30) the blade root which distribution facilities is done (32) has inside, in order with each blade root and the base of the bucket containment slot, for the gap which parallels to the bucket containment slot in the bucket not to occur, the plate for lock because it locks (56) is done distribution facilities, the turbine rotor for the gas turbine which becomes the installation and others re te in the turbine disk the plate for lock tucks and the section (58) depending upon (8) inThe cooling air supply aisle for coolant supply (48) has led to the base of the bucket containment slot, the plate for lock has the cooling air hole in order to pass through coolant (62), the blade root has two slots which extending are present substantially in magnetic declination direction vis-a-vis turbine axis (52), the plate for lock has in order to become joint possible to the said slot form joint, two tongues which distribution facilities are done (54).
