    5.Stator on PP. 1 and 2, that is, in that each shank is provided with protrusions having
    slots, and between the sleeves and the shanks are installed elastic plates in contact with the projections and secured. with their ends in the slot.
    6.Stator on PP. 1 and 5, characterized in that radial grooves for the passage of the ends of the plates are made in the side walls of the windows.
    7.Stator on PP. 1 and 6, in that the radial grooves are connected to the surface of the annular groove by an inclined surface.
    This invention relates to a sorrel construction compressor and concerns the stator structure of an axial compressor. The stator of the axial compressor is known, which includes a casing and blades with C 13 shanks are installed in it. The drawbacks of such a compressor are the manufacturing complexity and: rigid fixing of the blades. The closest in technical essence to the present invention is a stator, comprising a housing and rims of blades with tailings installed therein, placed in an annular groove of a T-shaped cross-section made on the inner surface of the housing r2J. The disadvantage of such a stator is the difficulty of assembling and installing the blades in the stator. The purpose of the invention is to simplify the failure. The goal is achieved in that at least one radial window for the introduction of blades, which is in communication with the groove, is made in the stator housing, and the shanks of all blades are covered by a chain. The chain is made in the form of bushings mounted on axles connected by rigid rods, and each sleeve is placed on the shank. The ends of the chain are connected with a tension coupling. The clutch is made in the form of a threaded pin, and the cylinders are fixed at the ends of the chain, and the pin is connected to the latter and provided with lock nuts. Each shank is provided with protrusions having slots, and elastic plates in contact with the protrusions and fixed with their ends in the slots are installed between the sleeves and the shanks. In the side walls of the windows there are radial grooves for the passage of the ends of the plates. The radial grooves are adjacent to the annular groove surface with an inclined surface. FIG. 1 shows a longitudinal section of a compressor having a stator; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 - scapula; in fig. 5 is a sectional view BB in FIG. 3. The stator includes a housing 1 and rims of blades 2 with shanks installed therein 3. On the inner surface of the stator T-grooves 4 are provided, communicated with a through radial window 5 for entering the blades 2. The shanks 3 of all blades 2 of each rim are covered by chain 6. Chain 6 is made in the form of plugs 7 mounted on axles 8 connected by rigid rods 9, and the ends of chain 6 are connected by means of a tension coupling 10. Each sleeve 7 of chain 6 is located on the tail 3 of the vanes 2. The stem coupling 10 can be made in the form of a finger 11 with thread 12
    and close 1. at the ends of the chain 6 of the cylinders 13 connected to a finger, which is provided with locknuts 14.
    Each shank 3 has protrusions 15 with slots 16, in which elastic plates 18 are fixed with their ends 17, contacting protrusions 15 and placed between sleeves 7 and shanks 3.
    In the side walls 19 of the windows 5, radial grooves 20 are made for the passage of the ends 17 of the plates 18, mating with the surface 21 of the annular groove 4 by the inclined surface 22,
    which facilitates the insertion of the blade 2 with the plate 18 into the groove 4.
    The stator is assembled as follows.
    The blades 2 of the crowns are alternately inserted into the window 5 and distributed around the stator circumference. Then, the shanks 3 of the blades 2 install the plates 18, pass them through the window 5 with the groove 20, and cover all the plates 18 circumferentially with the chain 6, install the sleeve 7 of the chain 6 on each plate 18. After that, the ends of the chain 6 are pulled together with the coupling 10, fixed this blade 2 in the stator. 10 V3 / 1 f3 f
