This invention is a turbomachine with a blade rotor according to the defining part of paragraph 1 of the claims.
Machines of this type are known, in particular from patent application for invention No. 1345097, filed September 15, 2003.
This document describes a mechanism in which fluid is directed perpendicular to the axis of the rotor blades, which are constantly regulated by a special control mechanism. Thus, the kinetic energy of the fluid, for example water, can be intercepted and trapped in the blades across their surface in a perpendicular position relative to the fluid flow, and the blades are not fixed, and such blades during rotation around the rotor axis represent the minimum obstruction to fluid flow when they do not generate any torque or only negative point. Therefore, in accordance with the density and physico-chemical properties of the fluid and the necessary energy is selected corresponding to the size of the blades and rotor.
Regarding this same mechanism, the same applicant has found that various aspects of the mechanism of this type can be improved to obtain the best results.
Thus, the aim of this study is the creation of a turbomachine, in which the kinetic energy of the fluid m is should be optimally used with maximum efficiency.
This goal is achieved by creating a turbomachine according to this invention with the features according to the claims.
According to this invention provides a turbomachine, comparable with srednemotornoy the turbine type "cross-current", with the axis perpendicular to the direction of the current of fluid, working with two (or more) coaxial or concentric rotors.
This machine is constructed in such a way as to intercept and absorb the maximum amount of kinetic energy of fluid flow (water and air), in which it runs. Each rotor consists of a rotating circular body and has a certain number of blades (two or more), usually located at equal distance on the virtual circle, the diameter of which is taken as the initial diameter of the rotor. The blades of each rotor are identical and symmetrical, and each of them can rotate around its axis of rotation parallel to the Central axis of the machine rotated through 360° in both directions.
The rotation of the blades around their own axis is regulated by a number of mechanisms (a variety of mechanisms known in the field), which provide the correct location of each of the blades relative to each other at an angle for supporting the rotor and to the direction of fluid flow.
Mechanical soy is inania these movements can easily be selected in accordance with the design requirements provided that there is a ratio of turns between the rotors and blades. This is achieved by directing blades designed to best capture the kinetic energy of the fluid, and in accordance with the position occupied by moment by moment during rotation of the rotor. Such movement is harmonious without oscillations or pulsations, since it always occurs in one direction and with the same speed, which is proportional to the rotation of the rotor, even when not being adjusted by means of the control mechanism or manually. The rotation of the blade is arranged so as to rotate 180° around its axis and counterclockwise relative to the current direction of rotation of its rotor, which at the same time performs a full 360° rotation around its Central axis. This also applies to all blades used in the main circle of the same rotor, and so on for each turn.
It is desirable that two of the rotor in relation to each other had the opposite rotation, and the same applies in relation to the movement of the respective blades. This helps compensate for the resulting tightening, because of which the machine may begin to rotate relative to the support base, and also compensates for other mechanical friction, which can affect the sensitivity to control the implementation. Such consequences you could face if only one rotor.
The speed of rotation of the rotor with a large diameter is usually less than this speed rotor with a smaller diameter, so as to maintain approximately the same peripheral speed proportional to the fluid velocity at the time of filing or passing. The speed of rotation of each rotor can be (mechanical) free and governed only by the shock effect of the fluid on the blades or be limited and coordinated a clear correlation between the two rotors. According to the requirements, you can make a manual choice of a free pair with two output forces, with differential or proportional limit.
Reverse rotation of the two rotors is achieved by using the direction of the pressure fluid on the blades, which due to its location and tilt (installed in the Assembly machine) capture the kinetic energy, transforming it into torque and partly by changing the direction of flow, which is their hits. They guide with corrective synergistic effect of the fluid to the following for their blades of one rotor and forth as long as the fluid does not pass through the entire system. However, if the Assembly you can create the necessary conditions so that the blades rotate in the same direction
The blade shape, provided that it is symmetrical about its axis, not must-have classic aerodynamic profile, but the front and rear edges must be identical, so that they can change their role at every revolution of the corresponding rotor.
It also indicates the presence of a huge number of options for scheme 0 with image sizes of blades, namely: short and wide blade, long and narrow blades, as well as all intermediate variants, provided that the blades of one rotor are identical and have a symmetrical shape. The dimensions of the machine and rotors, as well as the size, shape and number of blades should correspond to the expected energy and physical characteristics of the fluid and the conditions under which the work is performed. Materials for machinery are selected according to the planned design.
Usually the design of the machine has a vertical axis, but it can also be placed at an angle under the condition that the axis is perpendicular to the fluid flow. The machine can be equipped with a guide mechanism or other device that indicates the direction of fluid acts on the input control machine, designed to regulate the blades of both rotors at the same time. This mechanism can be combined with manual control with the help and input of the differential mechanism. The advantage of this machine over others is that this way you can easily focus only blades, even when the machine is running at full power and full orientation without the need to Orient the entire structure. It also gives you the opportunity to slow down, to stop the rotation and start the rotors rotate counter-clockwise with the same efficiency, with the full pressure of the liquid and without the need to interrupt operation of the machine.
This reversible system and, therefore, can function also as the impeller. If, instead of to take away power from the output shaft, connected to it a motor or similar mechanism, design of machine used in the opposite way, to create the pressure of the fluid in which it is immersed. Changing the number of revolutions, it is possible to regulate the pressure, and changing the position of the blades is also possible to direct the flow in any direction through 360°. With the undoubted advantage in maneuverability, especially in the field of navigation, with a Central pressure from the axis, which is fed continuously and without vibrations due to moving blades. Moreover, since the rotor rotates slowly enough, the risk of cavitation is negligible. The dimensions and proportions are always withstand one concept of functioning and are carefully selected in accordance with the spruce using impeller (in this case).
Further characteristics and variations of the embodiment will be described in the claims and some of the following descriptions of the preferred embodiments depicted in the attached drawings, namely:

In these figures, item 1 refers to the entire turbomachine according to this invention. It has a main body 2, in which the first rotor 4 by means of a bearing 3. Along the circumference of the rotor 4 are at least two blades 5 with a possibility of rotation, which are evenly distributed through the shafts 6, the axis of which is perpendicular to the rotor is 4. Each rotary shaft 6 is rigidly connected with the corresponding blade 5 and provided with a bevel gear 7 which engages with a bevel gear 8 fixed to the rod 9, the axis of which is perpendicular to the axis of the shaft 6 and which is rotatably supported by the rotor 4. On the rod 9 from the other end mounted bevel gear 10 which is in mesh with the bevel gear 11, is rigidly connected to the coupling 12, which, in turn, mounted with bearings 13 on a shaft 14 which is rotatably accommodated in the housing 1. The rotor 4 around its Central hole also contains the crown bevel gear 15 which is in engagement with the auxiliary gear 16 fixed on the shaft 17, is placed rotatably in the housing 1 and the axis of which is perpendicular to the axis of the crown gear 15. The shaft 17 also carries a second auxiliary gear 18 which engages with the front bevel gear toothed disk 19, mounted on the shaft 14.
According to this invention, the first rotor 4 is connected with the second rotor 20, which is rotatably supported by the bearing 21 of the first rotor 4, and contains at least two blades 22, which are evenly distributed along the circumference, and the blades are respectively mounted on the shaft 23 fixed to Roto the 20 with a possibility of rotation and the axis of which is perpendicular to this rotor. As with the first rotor 4, in this case, the shaft 23 also carries a bevel gear 24 with which they are connected, and which is in engagement with the bevel gear 25, mounted on a rod 26, which in turn is supported for rotation by the rotor 20 and the axis of which is perpendicular to the shaft 23, and which at the other end has a bevel gear 27, which engages with the bevel gear 28, which is mounted on the clutch 12. The rotor 20 is also rigidly connected to the shaft 14 by means of a flange 59.
On the clutch 12 is also rigidly mounted sprocket 57, connected by a chain 58 with the gear 29, is placed on the shaft 30 which is rotatably accommodated in the housing 1. Thus, the position of the coupling 12 may vary depending on the rotation of the shaft 30 and, therefore, changes the angular position of the blade 5 at any position of the rotor 4 relative to the fluid stream.
Figure 3 and 4 show a second variant embodiment, in which two turns of the first and second rotor compensated differential indicated by 31.
Differential 31 consists of a double crown gear 32, which is rotatably carried on the shaft 14 and with one hand is engaged with the first rotor 4 through the auxiliary gear 16, and on the other hand is engaged with the satellites 33 and 34 that are in contact in turn with a crown gear 35,mounted on the shaft 14, to which is rigidly attached to the second rotor 20. Satellites 33 and 34 rotate on the pins 36 of the wall of the basket 37, rotating around the shaft 14 and fixed to the output shaft 38. It is clear that the output shaft 38 serves as PTO for the consumer.
Thus, with the help of satellites 33 and 34, the movement of the second rotor 20 is optimally compensated for by the movement of the first rotor 4.
The following are additional features.
Thus, we obtain the main body 2, which forms the design of the whole machine and supports the rotor during operation. It can be used for both fixed and mobile design, depending on the conditions.

Adjusting input shaft 30 and the regulating sleeve can be connected, if not circuit 58, timing belt, gears or other means, provided that the transfer is permanent and does not slide.
The Central adjusting sleeve 12 is usually fixed and can rotate only in the case of rotation of the adjusting shaft 30. She holds two fixed crown 11 and 28 of the intermediate gears driving the blades of both external and internal rotor. Its motion controls simultaneous movement of all of the first intermediate gears as larger and smaller rotor.
Asterisk controlled by adjusting the shaft rotates together with the clutch. The second intermediate gear 8 (each blade) larger rotor has exactly half of the teeth compared to the number of teeth of the respective first intermediate vane gear.

Gear ratio between the Central crown and the crown, which is connected with the larger rotor is proportional to the steps between the small and large rotors. In terms of construction shown, is achieved by inversion of a course from a larger rotor and, thus, its direction aligned with the direction of the smaller rotor.

Central bevel gear is rigidly secured on one of ends of central shaft non-rotating around its axis and arranged vertically. Planet pinion members are arranged around central radially and uniformly. Shaft of each planet pinion member with bevel gears on its ends is made single-section, and bevel gear belonging to said shaft and pointed to side of blade of said planet pinion member engages with bevel secured rigidly and coaxially to smaller spur gear of blade reduction gear. Larger spur gear engages with smaller one, and it is secured on axle of blade installed vertically. Each blade rests by ends of its axle for rotation of brackets mounted by bases on cylindrical housing installed for rotation coaxially relative to central shaft, and tops of brackets at both ends of central shaft are connected by ring rims. Upper rim, being drive wheel, is coupled with energy converters. Central shaft rests by both ends with locking on framework provided with pontoon devices. Invention makes it possible to use river current energy with maximum efficiency at no adverse effect on environment caused by submersion of river flood lands caused by building of dams, energy of ocean currents, energy of tides and ebbs owing to use of blades with two points of support. Versions of design of water-wheel generators are provided in description.
EFFECT: simple design, high adaptability to manufacture and servicing of water-wheel generator.
