Abstract
1. Лопаточный венец (44) для осевой турбомашины, включающий в себя обод (46) для крепления лопаток, снабженный некоторым количеством имеющих опорные боковые стороны (23) крепежных пазов (21) для лопаток (27) и соответствующим количеством лопаток (27), хвостовики которых, выполненные соответственно крепежным пазам (21), вставлены в крепежные пазы (21),при этом по меньшей мере одна из лопаток (27), предпочтительно все лопатки (27) на своей обращенной к основанию (35) крепежного паза (21) нижней стороне (33) хвостовика имеет или, соответственно, имеют выемку (37), дно (59) которой по меньшей мере частично расположено наискосок к основанию (35) крепежного паза (21), и в которой в каждом случае расположен клиновидный стопорный элемент (47) для прижатия хвостовика (31) лопатки к опорным боковым сторонам (23),отличающийся тем,что в каждой выемке (37) размещен пружинный элемент (55), сила упругости которого воздействует по длине крепежного паза (21) на упомянутый клиновидный стопорный элемент (47),что выемка (37) ограничена первой боковой стенкой (39) и расположенной напротив первой боковой стенки (39) второй боковой стенкой (41),при этом пружинный элемент (55) с одной стороны опирается на первую боковую стенку (39), а с другой стороны на тупой конец (51) клиновидного стопорного элемента (47), ичто предусмотрены средства, с помощью которых клиновидный стопорный элемент (47) для монтажа лопатки (27) в крепежном пазу (21) без предварительного натяга может временно смещаться в положение, в котором хвостовик (31) лопатки установлен в крепежном пазу (21) без предварительного натяга.2. Лопаточный венец (44) по п. 1, у которого пружинный элемент (55) выполнен в виде пакета тарельчатых пружин, и в первой боковой стенке (39) предусмотрено отверстие (57), и через то и другое распространяется1. The shoulder blade (44) for an axial turbomachine, including a rim (46) for attaching the blades, equipped with a number of fixing grooves (21) for the blades (27) having supporting sides (23) and the corresponding number of blades (27), whose shanks, respectively made in the mounting grooves (21), are inserted into the mounting grooves (21), with at least one of the blades (27), preferably all the blades (27) on its facing groove (35) of the mounting groove (21) the lower side (33) of the shank has or, accordingly, have a recess (37), the bottom (5 9) which is at least partially oblique to the base (35) of the mounting groove (21), and in which in each case there is a wedge-shaped locking element (47) for pressing the shank of the blade (31) to the supporting lateral sides (23), characterized in that in each recess (37) there is a spring element (55), the elastic force of which acts along the length of the mounting groove (21) on said wedge-shaped locking element (47), that the recess (37) is limited by the first side wall (39) and located opposite the first side wall (39) the second side wall (41), pr and this spring element (55) on the one hand rests on the first side wall (39), and on the other hand on the blunt end (51) of the wedge-shaped locking element (47), that means are provided by which the wedge-shaped locking element (47) for mounting the blades (27) in the mounting groove (21) without preload may temporarily shift to the position in which the shank (31) of the blade is installed in the mounting groove (21) without preload. 2. The shoulder blade (44) according to claim 1, in which the spring element (55) is made in the form of a cup spring plate, and an opening (57) is provided in the first side wall (39), and through both
