Description

eleven

The invention relates to mechanical engineering and can be used in assembling rotors in the form of a part mounted on a shaft of a package.

The purpose of the invention is to reduce the operational imbalances of the rotor by preventing the rotor parts mounted on the shaft from moving.

The drawing shows a diagram of a rotor with a package of parts (disks).

On the shaft 1 installed average dis

ki 2 with imbalances D c and extreme disks 3 with imbalances D. There is a gap between the disks and the shaft 4. The disk pack is fixed and fixed to the shaft with nuts 5.

The method of assembling the rotor is implemented as follows.

The average disks 2 are oriented on the shaft 1 by the imbalances D t (in one direction and in the same direction they are displaced by the size of the gap 4. In the opposite direction the imbalances D are oriented and the extreme disks 3 are shifted by the size of the gap 4

The position is fixed to the disks on the shaft, stacked with their nuts 5.

When the rotor rotates, the centrifugal forces caused by the displacement of the disks and their imbalances D and b press the disks to the shaft, preventing their accidental displacement by the size of the gap, and reduce the operating imbalances of the rotor.
