The technical solution relates to the alternative energy industry, and more particularly to low-salient pole synchronous low-speed electric machines with a vertical axis of rotation of the rotor.

Known impeller radial-axial hydraulic machines (see the description of the invention to AS. the USSR №1603046, IPC F03B 3/02)containing the hub, the inner flanges, propeller shaft to the generator.

This impeller is designed to work as part of a hydrogenerator, it can be viewed as a prototype for the final result, but it cannot be used in the Electromechanical installation.

The closest analogue design can be considered as the wing of the plane, see, for example, the description of the invention to AS. the USSR №453889, IPC VS 3/18 "Metal strength member airframe structure of the aircraft, in which the wing is made in the form of cantilever beams decreasing cross-section, consisting of longitudinal side members, fastened to the vertical wall of the stringers and a covering of sheet material, the cross made the ribs.

The purpose of technical solution - the creation of the design of the impeller Electromechanical installations.

- The impeller is an integral part of Electromechanical installations. Its purpose, design and working conditions are completely different from the purpose of the design is AI and working conditions of hydraulic turbines.

In the Electromechanical installation impeller radius R is designed to convert the tangential or circumferential forces F acting on the peripheral or end his part in the mechanical lever moment M=R·F.

- When the operation of the Electromechanical installations on the impeller lever moment M=R·F operates continuously, it means the impeller generates torque MBP.=R·F with angular velocity Ω is also continuous.

- The efficiency of the impeller is greater, the greater the radius R of the radius of the rotor r of the electric machine. In this case, the magnitude of the required force F will decrease.

- The increase of the radius R of the impeller, due to a number of reasons, has limitations, so the ratio of Electromechanical installations: r, Ω, R, F, Rel., you must assign and calculate for each series of Electromechanical installations.

- Dimensions of the impeller can be significant, its radius can reach more than 20 meters, so the design must satisfy several conditions primarily strength and stiffness in the horizontal and vertical planes, not only from external forces F, but from internal mechanical stresses, in addition, the impeller may be affected by changes in ambient temperature from -50°C to +50°C, which can cause deformations (KOR the mix), and, as a consequence, the occurrence of vibrations.

- With the advent of the impeller with the new features and large size new, unknown to gidroenergostroenija (more precisely, the new energy industry): technology, production, Assembly, transportation and operation of new installations, units and components.

This objective is achieved in that the impeller is made in the form of a disk with radius R and height at the hub h1and in the peripheral end part of the h2equipped with the mounting elements of the site of application of the external force, the longitudinal-transverse frame is made of radial-ring, bonded to the hub, provided with a fastening to the drive sleeve Electromechanical installation consists of a radial rib configuration of the radial section of the disc and incomplete ribs, installed in the Central and peripheral parts of the disk evenly spaced around the circumference, which are rigidly fastened with multiple internal annular vertical side members, and the outer end outside the spar reinforced and fitted with the outer side of the mounting elements of the site of application of the external force, and the inner side of the annular horizontal shelves, which it is rigidly connected with the ribs, top and below the radial-circular frame is bonded with the covering, the value of R is the disk radius greater than r, radio is and rotor Electromechanical installations, and the value of h1larger values of h2.

On the submitted drawings submitted by: figure 1 shows the impeller (top view without top covering), figure 2 shows the impeller (side view), figure 3 shows the outer mounting spar (radial section), figure 4 shows the connection node of the hub of the impeller with the drive sleeve (section along the vertical radial plane).

The device (see figure 1, 2). To the hub 1 rays radially attached ribs 2 having the configuration of a radial cross-section of the impeller. The plane of each rib coincides with a vertical radial the major plane of the impeller and has the greatest vertical height h 1in the hub 1, and the smallest height h2on its end face. With increasing radial length from the hub to the end of the set of incomplete rib 3 different lengths. All rib set evenly around the circumference. In the horizontal plane of the impeller set ring rails 4 with a vertical height equal to the height of the ribs. External outer face side member 5 (see figure 3) enhanced, finishes and pulls the radial-circular frame of the impeller, in addition, it is equipped with the outer side of the mounting elements of the node the application of an external force, for example, a horizontal annular thick-walled mounting shelves 7 with a vertical hole 8 with a uniform interval, which are the components of the mechanism of application of the external force. The inner side of the side member 5 provided with a horizontal annular mounting shelves 9, which he fastened with ribs 2 and 3.

To the radial-circular frame at the top and bottom attached to the casing 6 of sheet metal, which increases the rigidity of the whole structure. In the lower panels made drainage holes 3-6 mm removal by gravity, possibly formed, moisture from condensation.

The connection of the impeller to the electric machine Electromechanical installations performed by the drive sleeve 10 (see figure 4), which is temporarily the th Assembly and technological detail, the purpose of which is to provide separate manufacture, installation, commissioning of the impeller and the electric machine. The drive sleeve 6 consists of two parts, is provided with radial locks 11, in which, in the working position, is the hub 1 of the impeller. Fixed rigid connection of the drive sleeve 10 with wheel hub 1 is provided with a vertical bolts through holes 12.

The drive sleeve 10 is made and customize to the electric machine (to the splined connection of the rotor shaft), then the electric machine can be sent to the customer for installation, and the drive sleeve 10 on the factory site for fitting and mounting thereto the hub of the impeller.

The effect of technical solutions that created a fundamentally new functional item Electromechanical installation impeller in the form of a disk with radius large radius of the electric machine.
