This invention relates generally to a power drive mechanism and has for its object the provision of an improved unit of this character which has improved controllin means,
the invention being in the nature 0 an imindividually and independently during the rotation of the wheel, the invention further relating to a construction and arrangement in which an individual power unit is provided for each of the blades upon the blade wheel, so as to permit the operation of each.
blade with the relative motion desired, and to control it in accordance with the working conditions encountered and results to be attained.
In carrying out our invention the power units are combined with the wheel body to turn therewith and are arranged to operate the blades directly; and in accordance with our invention the power units for such purpose may consist either of electric motors, or of motors adapted to be operated by gases or liquids under pressure.
A further object of our invention is the provision of a simple, compact, self-contained power drive mechanism of the character described and for the purpose set forth, one in which the operation of the blades can be regulated and controlled without the use of troublesome compensating devices such as sprockets, gearing, eccentric discs, and similar mechanical transmitting devices conventionally employed for such purpose.
With the foregoing and other objects in view, the invention consists in the improve power drive mechanism and in the form,/construction, relative arrangement or arrangements of its parts, as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the sub-joined claims.
For a full understanding of the invention, reference is to be had to the accompanying drawings, forming a material part of this application, and in which:
Fig. 1 represents a central cross section through a wheel body provided with blades and individual electric motors for the blades Fig. 2 represents a central cross section through a hydraulic motor with electric control and compensating means;
Figs. 3, 4, 5 and 6 are detail views taken,
respectively, on the lines A B, CD, E F, G-H, of Fig. 2;
Flg. 7 represents a diagrammatic view showing a modified form of construction,
including a primary and secondary wheeldrive and connecting means for synchronizing the operation of the same; and
ig. 8 represents a diagrammatic view showing a modified construction for synchronizing the operation of the primary and secondary wheel devices.
companying drawings, and first to the ex- Wi h more partlcular reference to the acemplificatiori shown n Fig. 1, it will be seen that the wheel body 7 is equipped with six blades, of which only blades 1 and '2 situated in the plane of the section and blades 3 and 4 situated behind the plane of the section are Visible. The mobility of the blades with this wheel consists in that each blade may be turned round an axis parallel to the wheel axis. Blade 3 for instance may be turned round axis 56. The electric motors 8 are fastened to the wheel body 7, and their movable parts are connected with the blades.
These motors may be made to operate the blades With auniform revolution, with. an uneven rotation or with a swinglng motion,
according to their inner construction and the momentary course of the supplied elec-' trical current. The current is supplied to the motors over cable 9, slip-rings 10, and brushes 11, through a cable'12 which leads to the generator, not shown in the drawings,v
18 and 19 are formed. Cylinder chambersbilities for realizing the invention.
18 and 19 are connected by' channels 20 and 21 and by clearances in a rotary valve 22 with pipes 23 and 24 through which the pressure liquid is supplied and discharged. Rotary valve 22 is controlled by rotating magnet 25, the momentary position of which depends upon the electrical excitation of field-magnets 26. By cable 27 the field-magnets are connected with the electric control. If rotary magnet 25 turns under the influence of the control rotary valve .22- opens clearances 20 and 21 in such manner that one side of the cylinder gets into communication with the supply pipe. and the other with the discharge ipe.
The pressure di erence is acting now on piston 15 and turns the stem 14 with the blade in the same direction and by the same angle by which rotary magnet 25 had turned. The stem 14 having covered this angle the mutual position of the clearances in the rotary valve and in stem 14 is again the same as before the beginning of the movement, that means the current is interrupted and the movement efinished. This motor thus has a compensating device whereby the movement of the blade becomes an exact copy of the movement of the rotary magnet.
The arrangements shown in the drawings represent two optional examples of .possri e could indicate a great number of other arrangements, with a different osition of the blades to the wheel and di erent relative movements, and further with motors and controldevices totally different front the two examples shown which are deemed sufficient to illustrate a practical application of the idea of the invention.
In Fig. 7 we show a synchronizing rocess whereby, duringthe operation o the blade wheel, each blade motor temporarily receives an impulse which tends to bring the blade in a certain position; the release of this impulse from the primary machine, which belongs to this blade motor, or generally from theenergy source or from the control device, is automatically done only when the primary machine is in a position which, corresponds to the above named blade position.
Reference character 28 (Fig. 7') denotes the primary'machine and 29 the secondary machine (blade motor) and both machines are supposed as rotary piston machines. .The primary machine 28 essentially consists of may be moved to and fro by any suitable I means, for instance by a link bar 38.
If both casings 30 and 33 and pipings 36 and 37 are filled with a pressure liquid the pressure rise produced on the left side of the machine with the rotary piston swung to the left is communicated-by piping 36 to the right side of secondary machme 29 whereby rotary piston of the secondary machine is swung to the left, that is to say in the same direction as the rotar iston of the primary machine. The liquid displaced from the left side of the secondary machine flows through piping 37 to the right. side of the primary machine.
If now by any leakages or through other occurrences the exact synchronism of the two rotary pistons 32 and 35 becomes deranged, it will be automatically re-established and this may be done in the following manner:
At the axis of. rotary piston 35 of the secondary machine an arm 39 is arranged at the end of which is a head 40 situated between the stops 41 of rods 42 which slide in their longitudinal direction and are loaded by springs 43 in such a manner that the stops 4lare pressed against head 40 of arm 39. The outer ends of rods 42 are provided behind the gearings 44 with stops 45 limiting the movement of rods 42 in the direction of head 40, so that" when the head 40 isin the middle position the springs 43 do not exert any pressure on it.
Casing 30 of the primary machinehas a canal 46 which, when rotary piston 32 is in the middle position, connects the right and left side of the casing with each other so that in this middle position an equalization of pressure between the two piston sides may take place. often as rotary piston 32 of the primary machine reaches this middle position both piston sides are temporarily connected with each other and the one-sided pressure exerted on secondary piston 32 temporarily will cease so that, if in this moment rotary piston 35 should be in one or the other direc tion outside of its middle position, one of the two springs 43 can bring arm 39 and thus also rotary piston 35 into the middle position.
' .However'the rotary (piston 32 of the primary machine shuts own at once again Therefore as pressure equalizing canal 46 forcing the secondary piston 35 to move in the same direc-' tion.- The described arrangement has only the efi'ect that with every movement to and fro, as, often as the primary piston arrives in its middle position, the wrong position of the secondary piston is corrected. In Fig. 8 the primary machine 47 and secondary machine 59 are developedas rotary piston machines and also in this case the side on the left of rotary piston 48 of the primary machine is connected by piping 49 with the side on the right of rotary piston-'50 of the secondary machine, and the right side of the primary machine with the left side of the secondary machine by pi ing 51. The trunnion of rotary piston 50 o the secondary machine is hollow and has two openings 52, of which each is situated on one side of piston 50. Inside of the hollow trunnion a rotary valve 53 has been arranged having, two canals 54 and 55 and between them a bridge. This bridge normally closes the two openings 52' of the piston trunnion; canal 54 isconnected through piping 56 (shown in dash-dotted lines) with a pressure-liquid tank (perhaps an air tank of a liquid pump) and canal 55 through piping 57 (shown in dash-dotted lines) with the discharge. Rotary valve 53, is'connected with the trunnion of rotary piston 48 of the primar machine by a gearing 58 in such a manner t at rotary valve 53 moves exactly like rotary piston 48.
As long as a perfect synchronism exists between the two rotary pistons 48 and 50 no relative displacement will occur between rotary valve 53 and rotary piston 50 of the secondary machine, because rotary valve 53 as shown by the example through rods 58 follows forcibly the movements of rotary piston 48 so that with perfect synchronism openings 52 remain always closed, and be cause rotary valve 53 and rotary piston 50 are moving quite in the same way. Should, however, the movement of rotary piston 50 fail to synchronize when the movement of rotary valve 53 one of the openings 52 is put into communication with canal 54 and the other one with canal 55 thus causingthe correction. If for instance rotary piston 50 remains back when rotary piston 48 moves to the left canal 54 will come into communication with the right handed 0 ening 52 and thus with the right side 0 the secondary machine, and the pressure liquid from piping 56 will exert its pressure on the right side of the secondary machine in. such a manner that rotary piston 50 will receive a correcting impulse. Canal 55 simultaner ously comes into communication" with the left handed opening 5220f the hollow trunnion and therefore pressureliquidcan discharge from the left side of the secondary machine through piping 57 into the open air thus allowing the synchronizing impulse to be exerted without difiiculty. With the re-establishment of synchronism, the openings 52 are closed again. The more rotary piston 50 remains back behind piston 48 and rotary valve 53, the greater becomes the impulse, which has to re-establish the synchronism, and vice-versa, and this synchronizing im ulse will occur on every place of the way 0 the piston wherever an asynchronism should occur, contrary to the proceeding shown by Fig. 7 where the correcting impulse can take place only at a determined place of the way, which place, it is true, can be chosen now optionally after the con structive execution of the device.
Figs. 7 and 8 only serve for explanation of the two above mentioned methods, however it shall not be pretended that this synchronizing process maybe performed only with machines of the above mentioned type and only with the indicated constructive means.
