The operation principle of the present embodiment is: the power shaft 1 (speed end) of cam type straight wing suspension magnetic eddy-current coupling connects the first motor, and the output shaft 2 (low speed end) of cam type straight wing suspension magnetic eddy-current coupling connects load.After the first electric motor starting, air-gap separation and the air-gap separation between right disk 35 and right conductor disc 32 between left disk 34 and left conductor disc 31 is regulated by air-gap separation governor motion, and then the transmitted power of this shaft coupling can be adjusted, and then the rotating speed of adjustment output shaft 2.Specific as follows:
Start the first motor, the power shaft 1 of cam type straight wing suspension magnetic eddy-current coupling and the synchronized rotation of the first motor, power shaft 1 drives left conductor disc 31 and right conductor disc 32 synchronous axial system; Left conductor disc 31 drives left disk 34 to rotate by current vortex, right conductor disc 32 drives right disk 35 to rotate by current vortex, when left disk 34 and left conductor disc 31 are distant with right conductor disc 32 apart from, right disk 35, the current vortex that the magnetic induction line that left disk 34 sends produces in left conductor disc 31 is little, the current vortex that the magnetic induction line that right disk 35 sends produces in right conductor disc 32 is little, thus the transmitting torque of left conductor disc 31 to left disk 34 is little, the transmitting torque of right conductor disc 32 to right disk 35 is little, causes left disk 34, right disk 35 rotating speed lower.Due to left and right disk and telophragma 36 synchronous axial system, telophragma 36 is fixedly connected with output shaft 2 again, and left and right disk running speed reduces just to be equivalent to output shaft 2 rotating speed and reduces.Otherwise, after distance between left disk 34 and left conductor disc 31, the distance between right disk 35 and right conductor disc 32 reduce, left conductor disc 31 improves the transmitting torque of left disk 34, right conductor disc 32 improves the transmitting torque of right disk 35, left and right disk running speed improves, and output shaft 2 rotating speed improves.
The transmission process of air-gap separation governor motion is: the handle 45 on rotary sleeve cylinder 42, the first slide block 44 on outer sleeve 42 slides on the oblique chute 43 of inner sleeve 41, this oblique chute 43 is a part for helix, and inner sleeve 41 limited restrictions cannot move axially, therefore handle 45 drives outer sleeve 42 to rotate and moves axially the screw of compound, be connected by double-row roller bearing between outer sleeve 42 with right disk 35, this double-row roller bearing transmitting thrust does not transmit rotation, when outer sleeve 42 rotates advance (rotating and move axially the screw of compound), outer sleeve 42 can pull right disk 35 to move axially, right disk 35 can not be driven to rotate (due to the existence of double-row conical bearing between outer sleeve and right disk, therebetween not transmitting torque).Right disk 35 drives the second slide block 52 to move on slide bar 51 by right connecting rod 54, and the second slide block 52 drives left disk 34 to move towards the direction relative with right disk 35 by left connecting rod 53 again.When left disk 34 outwards moves with right disk 35, air-gap separation between left disk 34 and left conductor disc 31 reduces, air-gap separation between right disk 35 and right conductor disc 32 reduces, left conductor disc 31 increases the transmitting torque of left disk 34, right conductor disc 32 increases the transmitting torque of right disk 35, left and right disk running speed improves, and output shaft 2 rotating speed improves; When left disk 34 inwardly moves with right disk 35, air-gap separation between left disk 34 and left conductor disc 31 increases, air-gap separation between right disk 35 and right conductor disc 32 increases, left conductor disc 31 reduces the transmitting torque of left disk 34, right conductor disc 32 reduces the transmitting torque of right disk 35, left and right disk running speed reduces, and output shaft 2 rotating speed reduces.Like this, by the air-gap separation between left disk 34 and left conductor disc 31 and the air-gap separation between right disk 35 and right conductor disc 32, the speed discrepancy between power shaft 1 and output shaft 2 can just be adjusted.
3rd slide block 65 slides in cam path 64, sharf 62 is rotating around power shaft 1, due to the misalignment power shaft 1 of cam path 64, like this, 3rd slide block 65 can drive sharf 62 rotation by dwang 66, so, blade 61 is while rotating (revolution) around power shaft 1, also can drive rotation (elevating movement) by the 3rd slide block 65, this rotation makes attack angle of blade change, thus the motion of blade 61 meets the blade movement rule of voith schneider propeller under the control of cam path.The size and Orientation of making a concerted effort that the track of cam path 64 produces according to required blade rotation and given, once the track of cam path is given, in motion process, the size and Orientation of making a concerted effort no longer changes.When design, the weight of shaft coupling to be known in advance, according to the track of this weight configuration cam path 64, to make the gravity making a concerted effort to balance shaft coupling of blade rotation.Thus, can eliminate due to the moment of flexure that each parts gravity produces on power shaft 1 and output shaft 2, increase the useful life of cam type straight wing suspension magnetic eddy-current coupling.In the present embodiment, vane airfoil profile is NACA aerofoil profile.
The principle of voith schneider propeller is described with reference to Fig. 4: Fig. 4 is the schematic diagram of individual blade when diverse location, sharf is by a left side, right conductor disc drives and revolves round the sun centered by power shaft, sharf is equivalent to the A point in Fig. 4, revolution center is O1, 3rd slide block rotates in the cam path that power shaft is departed from the center of circle, 3rd slide block is equivalent to the B point in Fig. 4, the center of cam path is 02, A, line AB between B is equivalent to dwang, as can be seen from the figure, in the process that A Dian Rao center O1 rotates and B Dian Rao center 02 is rotated, AB can rotate, this rotation is the rotation of dwang.In figure, this rotation is presented as the change of angle of attack a.By changing the track of cam path, the namely path of B, can change the size and Orientation of making a concerted effort of blade.
The athletic meeting of blade improves the wind speed of interior flow field greatly, obviously improve heat-sinking capability, this is very favorable to the work of Ru-Fe-Mn permanent magnetic material, because the ability to work of Ru-Fe-Mn material is very high to the requirement of temperature, temperature is one of main factor affecting Ru-Fe-Mn material operating efficiency, even can completely lose ability to work when temperature is more than 85 degree.
The buoyancy that blade between left and right conductor disc produces counteracts gravity, power shaft and output shaft are no longer subject to the impact of moment of flexure, also no longer mutually tilt because of gravity between conductor disc and disk and even collide, thus large-scale and ultra-large type magnetic eddy-current coupling disk depth of parallelism problem under gravity can be solved, the sag problem of axle adds the useful life of shaft coupling.
