Claims (9)

1. Короткозамкнутый ротор для асинхронной машины, содержащий закрепленный на валу и удерживаемый с обеих сторон прижимными кольцами пакет (2) железа для размещения стержней (3) беличьей клетки, которые за пределами пакета (2) железа прочно соединены каждый с короткозамыкающим кольцом (4), опирающимся в радиальном направлении на установленное на валу (1) опорное кольцо (6), отличающийся тем, что оба прижимных кольца аксиально дистанцированы от пакета (2) железа и одновременно образуют опорное кольцо (6) для короткозамыкающего кольца (4), при этом между торцом пакета (2) железа и опорным кольцом (6) предусмотрены распорные ребра (7), выполненные преимущественно за одно целое с опорным кольцом (6).1. A short-circuited rotor for an asynchronous machine, comprising an iron packet (2) secured to the shaft and held on both sides by pressure rings to accommodate squirrel cage rods (3), which are firmly connected to the short-circuit ring (4) outside the iron packet (2) radially supported by a support ring (6) mounted on the shaft (1), characterized in that both pressure rings are axially spaced from the iron stack (2) and at the same time form a support ring (6) for the short-circuit ring (4), between spacer ribs (7) are provided to the end face of the iron bag (2) and the support ring (6), made predominantly in one piece with the support ring (6). 2. Ротор по п. 1, отличающийся тем, что короткозамыкающее кольцо (4) прилегает своей внутренней периферией непосредственно или на отдельных отрезках через первый упругий элемент (10) к наружной периферии опорного кольца (6) и прижато к нему усадочным кольцом (5), охватывающим короткозамыкающее кольцо (4). 2. The rotor according to claim 1, characterized in that the short-circuiting ring (4) abuts directly or on separate segments through its first elastic element (10) to the outer periphery of the support ring (6) and is pressed against it by a shrink ring (5) covering the shorting ring (4). 3.

Ротор по п. 7, отличающийся тем, что осевой выступ (13) на опорном кольце (6') прилегает своей боковой поверхностью со стороны вала к стенке паза со стороны вала, а при необходимости входит в паз (14) на короткозамыкающем кольце (4') даже с геометрическим замыканием. 8. The rotor according to claim 7, characterized in that the axial protrusion (13) on the support ring (6 ') abuts with its lateral surface from the shaft side to the groove wall on the shaft side, and if necessary, enters the groove (14) on the short-circuit ring (4 ') even with geometrical closure. 9. Ротор по п. 7, отличающийся тем, что между внутренней боковой поверхностью выступа и близкой к оси стенкой паза вложен упругий элемент, преимущественно гофрированная пружина (10). 9.
