Abstract
1. Устройство (10) для осевой фиксации рабочих лопаток (14) в роторе (23), содержащее буртик (21) вала, на наружной периферии (52) которого (буртика) выполнены проходящие в осевом направлении ротора (23) удерживающие пазы (12), в каждом из которых рабочая лопатка (14) расположена своей соответствующей удерживающему пазу (12) хвостовика (54), расположенный на торцевой боковой поверхности (56) буртика (21) вала в зоне удерживающих пазов (12) выступ (58), в котором выполнен открытый радиально наружу, огибающий паз (20), и выполненные в каждой рабочей лопатке (14) открытые радиально внутрь предохранительные пазы (24), каждый из которых расположен радиально напротив огибающего паза (20), причем для осевой фиксации рабочих лопаток (14) в огибающие и предохранительные пазы (20, 24) вставлены листовые уплотнительные элементы (42), образующие в направлении (U) периферии торцевое уплотнительное кольцо, отличающееся тем, что для фиксации уплотнительных элементов (42) от смещения в направлении (U) периферии, по меньшей мере, один из них имеет отверстие (63), а в боковой поверхности (56) буртика (21) вала выполнена приблизительно совпадающая с отверстием (63) выемка (65), в которую вставлен блокировочный элемент (67) с выступающим из его торцевой стороны, входящим в отверстие (63) пальцем (69), причем блокировочный элемент (67) фиксирован от потери посредством пластически деформирующей его подчеканки. ! 2. Устройство по п.1, у которого блокировочный элемент (67) по отношению к своему положению монтажа имеет в зоне выемки (65) клинообразное сечение. ! 3. Устройство по п.2, у которого выемка (65) выполнена в соответствии с клинообразной формой блокировочного элемента (67), а боковые стенки (66) вы 1. Device (10) for axial fixation of working blades (14) in the rotor (23), containing a shaft collar (21), on the outer periphery (52) of which (the collar) there are holding grooves (12) extending in the axial direction of the rotor (23). ), in each of which the working blade (14) is located in its corresponding holding groove (12) of the shank (54), located on the end side surface (56) of the shaft collar (21) in the area of the holding grooves (12) protrusion (58), in in which there is an open radially outward, enveloping groove (20), and safety grooves (24) open radially inward, made in each working blade (14), each of which is located radially opposite the enveloping groove (20), and for axial fixation of the working blades (14 ) sheet sealing elements (42) are inserted into the envelope and safety grooves (20, 24), forming an end sealing ring in the peripheral direction (U), characterized in that for fixing the sealing elements (42) from displacement in the peripheral direction (U), at least one of them has a hole (63), and in the side surface (56) of the shaft collar (21) there is a recess (65) approximately coinciding with the hole (63), into which a locking element (67) is inserted with a protruding the end side, entering the hole (63) with a finger (69), and the locking element (67) is fixed from loss by means of plastically deforming it. ! 2. A device according to claim 1, in which the locking element (67) has a wedge-shaped cross-section in relation to its mounting position in the area of the recess (65). ! 3. The device according to claim 2, in which the recess (65) is made in accordance with the wedge-shaped shape of the locking element (67), and the side walls (66)
