Description

one

From: 0bretbn. It relates to the area of .MaimnHOCTipoeHH electro, and has about the devices for: Kliivanivi and grooves (rotors of turboturbators.

A similar device is known, in which the pelvic part 0 | of the winding is pressed neocolony: and the punches, the ip of the arm along the closed slot, and acting in a radial direction, and as the wedge progresses, the press section is freed from the radial punches.

TaiKoe device is easy to use because it is impossible to access the salt; the mom of the groove is not removable (bandage rings and wedges, and | I am adjacent to the predetermined section of the groove.

A distinctive feature of the proposed (the device; the device is that the wedge is made so that its maximum size: me; p in any plane, parallective dpu pava, does not exceed the width of the iniasa in the same plane. When the groove is filled with magnetic material rigidly connected or made in one piece with the element that fills the groove. At least one of the wedges in oiaisiy can be covered from the bottom of the groove U-ab | different bracket so that (the axial gaps between the wedges are filled with U-shaped projections staples.

This provides in the wedged rotor the access “to the contents of the groove on the individual

plots without wedging adjacent groove areas.

FIG. 1 1I13ob.obeno proposed device made in the form of a wedge, cross section; in fig. 2 - the same plan view; on fit. 3 - device with balancing weight; on ifiig. 4 is a view along arrow A in FIG. 3; in fig. 5 is a view along arrow B in FIG. 3; in fig. 6 - rotor groove, spell: willow: by the proposed device, axonometric projection; ea fit. 7 - device in the working, position, axonometric projection; in fig. 8 - the proposed device, mounted (In the groove of the rotor, the cut.

In the groove / wedge 2 is installed, supported in the groove by the pads 3. In this case, the BbinOvi wedge so that when it rotates around axis 4, it does not extend beyond the circumference 5 in the broadened part of the groove / and beyond the circumference 6 in the narrow part of the groove /. Dia; the meter of circles 5 and 6 exceeds the width of the groove in the broadened and narrow portions of the width of the groove in the broad and narrow parts. This allows the wedge to be removed and inserted without moving it along the groove / a of the rotor.

The wedge 2 can be rigidly attached (or made in one piece with it) Eotement 7, which serves to fill the groove / and is simultaneously a balancing weight. During the rotation of the wedge 2 together with the element 7 of the BOKpyr axis 4 e, the element 7 also must not exceed the limits of the circle €.

On the slot section, not with a half-case of magnetic material, into the groove | P01mesh, ena U-shaped rubbing bracket 8, spring-loaded 9. At the same time, lanka 10 can be placed on the bottom.

In section D (Fig. 8), the groove is filled with bars 11-M: magnetic material, “this groove can be wedged by the currently used wedges. At the D and D-2 sites, the groove is K1. The Zhean is filled with bruoks and magnetic (mate riala, but these bars have a height,; instead of the width W of the bar.) In this area, the groove is wedged with “lines” (see fig. I- 2). On (section E, the balance rods 7 are located in the groove, you put it in one place, but it is complete with the wedge; or rigidly attached to them. In this area the wedge is wedged with a bala g. Weight. In the section Ж, an H-shaped locking okobu spring-loaded spring is placed in the groove. This section is closed in the following way.

The spring 9 and the locking bracket 8 are inserted into the groove. They are inserted into the groove | CLI (H 2 so that the pivot axis 12 of the wedge is aligned along the axis of the groove. Pressing the wedge 2, insert the locking cramp 8 deep into the groove. After the 1st wedge, two) into the groove up to lypiOBHfl of his working PShlozhen, the wedge is turned 90 °, (at that the pivot clamp 8 is raised by the spring 9 and the shoulder 13 o: grabs, does not allow it to rotate around the axis 4.

The number of sections along the length of the rotor groove. Can be any and they can be placed in the most diverse sequence.

Access to the contents of the M101Mu is provided in any place along the length of the groove. For example, if

Under the balancing conditions, it is necessary to remove the excess weight on the section E of the rotor, disassemble the section OK, then section D2 and remove the bar placed on the section

E, after which this section is wedged clip.

If conditions are required, balanuiroi ki is required (to add weight in any place, the sections are rearranged so that

in the required place there was a cannon; K magnetic material, or a balancing weight. All these operations were performed without a gang of rings.

Subject invention

1. A device for wedging the grooves of the rotor of the turbogenerator tour, an extra iB of the wedge, characterized in that, in order to clearly allow access to the contents of the groove in separate sections without wedging the adjacent sections of the groove, the wedge (so designed). .in a plane parallel to the groove of the slot does not exceed the slot of the slot in the same plane.

2. The device according to. 1, characterized in that, in order to simplify the installation and remove the accompanying groove when the latter is filled with the 1 magnetic Matrix, the wedge is rigidly connected, or made in one piece with the element filling the groove.

3. Device but nn. 1 and 2, distinguishing those) M,: that, in order to provide .fixation of wedges from sa) M-turn around iOCH, perpendicular to the bottom of the groove, and from self-torsional movements IB axial Direction, at least. , in the groove is covered from the bottom of the groove by the U-shaped bracket so that the axial clearances of the 1m. between the wedges are filled with the projections of the U-shaped bracket.
