Abstract
1. Приводное устройство (21) для поворота регулируемых лопаток (19) турбомашины, содержащее окруженный ободом (22) для крепления лопаток кольцеобразный участок (23) проточного канала, который проходит вдоль средней оси (24) обода (22) для крепления лопаток и в котором предусмотрены в виде лучей с образованием венца лопатки (19), при этом для перестановки лопатки (19) установлены каждая с возможностью поворота вокруг своей продольной оси (31) и имеют каждая проходящую по меньшей мере в обод (22) для крепления лопаток цапфу (26), которая соединена по меньшей мере с одним поворачиваемым в окружном направлении установочным кольцом (28), которое приводится в движение с помощью по меньшей мере одного двигателя (33), при этом приводной вал (35) двигателя (33) соединен с установочным кольцом (28), соответственно, установочными кольцами (28) с помощью зубчатой передачи, отличающееся тем, что предусмотрено несколько двигателей, соответствующий приводной вал (35) которых содержит одну из цапф (26) или жестко соединен с одной из цапф (26), при этом соответствующая зубчатая передача расположена на цапфе (26) приводимой тем самым непосредственно в движение лопатки (19), и что обеспечивается возможность привода остальных лопаток (19) с помощью по меньшей мере одного установочного кольца (28).2. Приводное устройство (21) по п. 1, в котором два установочных кольца (28) соединены с цапфой (26) и предназначены для привода с помощью двигателя (33), соответственно, двигателей.3. Приводное устройство (21) по любому из пп. 1 или 2, в котором в окружающем обод (28) для крепления лопаток или ободы (28) для крепления лопаток корпусе предусмотрена окружная канавка (27), в которой заканчиваются цап1. A drive device (21) for turning the adjustable blades (19) of a turbomachine, comprising an annular section (23) of the flow channel surrounded by a rim (22) for attaching the blades, which runs along the middle axis (24) of the rim (22) for attaching the blades and in which are provided in the form of rays with the formation of the crown of the blade (19), while for permutation the blades (19) are installed each with the possibility of rotation around its longitudinal axis (31) and each have a journal ( 26), which is connected to at least one locating ring (28) rotatable in the circumferential direction, which is driven by at least one motor (33), while the drive shaft (35) of the motor (33) is connected to the locating ring (28), respectively, with setting rings (28) using a gear train, characterized in that several motors are provided, the corresponding drive shaft (35) of which contains one of the trunnions (26 ) or rigidly connected to one of the trunnions (26), while the corresponding gear train is located on the journal (26) of the blades (19), thus directly driven, and that it is possible to drive the remaining blades (19) using at least one set ring (28) 2. The drive device (21) according to claim 1, in which two locating rings (28) are connected to the journal (26) and are intended to be driven by a motor (33), respectively, motors. 3. The drive device (21) according to any one of paragraphs. 1 or 2, in which a circumferential groove (27) is provided in the surrounding rim (28) for attaching the blades or the rim (28) for attaching the blades to the housing, in which the pin ends
