Abstract
The utility model relates to a diverter-pole DC generator, which adopts a generation coil fixed on a frame and a rotary magnet. However, the two poles of the magnet are respectively installed on two revolving bodies forming a rotor, and the two revolving bodies are in reverse rotation with circumferential velocity. The generation coil is a conductor wire with each loop passing through the axle center of the rotor and enveloping the occupied space by the two revolving bodies in a radial shape. Therefore, a DC generator without a phase changer can be obtained, the application range is broadened, and the output voltage is raised.
Description
The invention belongs to technical field of motors.
Have all knowing of basic electrotechniical people, existing DC generator all is to do direct current output after by commutator the alternating current that produces in the power coil being commutated.Because the easy arcing in contact is led in disconnected, the continued access of commutator segment in the commutator and carbon brush.This has not only limited the direct use of DC generator in explosive place, and makes the output voltage of this generator be limited in a lower scope.
The present invention proposes a kind of DC generator, its objective is under the prerequisite that satisfies direct direct current output, remove commutator, eliminate the weakness of the DC generator that causes by commutator, to obtain to export high voltage, no-spark, the pulseless DC generator of electric current with this.
Technology of the present invention constitutes: keep existing generator pit, form rotor with a hollow shaft and two metal derbies, hollow shaft is fixed (do not have and rotate) on support, two metal derbies axis hole and bearing by the middle part is contained in side by side and forms two revolving bodies on the hollow shaft, in two metal derbies each all the end in two ends (gyroaxis is the center) be magnetic, and two metal derbies are the S utmost point and the N utmost point respectively.Have between two metal derbies by 3 to 4 bevel gears, the gyroaxis of wherein fixing one or two remaining gear of a bevel gear on each metal derby is fixed on support or the hollow shaft.Formative gear obtains the reverse drive relation of two metal derbies thus to the top engagement, promptly when a metal derby rotates, drives another metallic plate oppositely with the speed rotation by gear train.Power coil of the present invention is to be wrapped on the coil holder that is fixed on the support, and all surrounds the occupied cylindrical space of metal derby rotation radially through hollow axis hole with an every circle of lead.
Use good effect of the present invention to be: because power coil is fixed, therefore can fixedly connected, cancel commutator with external circuit.This has just enlarged the environment for use scope and the DC generator that produces than high output voltage of DC generator.Simultaneously because two metal derby magnetic poles are all opposite with rotation direction, and the electric current that then produces in coil is the result of addition, and again because whole winding is a wire radiation distribution, so electric current is extremely steady.
Accompanying drawing 1 is overall schematic of the present invention, and 1 is support among the figure, and 2 is rotor, and 3 is power coil, and 4 is bobbin.
Accompanying drawing 2 concerns schematic diagram between two metal derbies among the present invention and the position of rotor between enclosing with generating one, and wherein 2a is a hollow shaft, and 2b, 2c are metal derby, and 3 is power coil.
Implementing manufacturing of the present invention and use is: according to the power and the output voltage of selected generator, design the size and the quantity parameter of each member, make support (1) by prior art.Slightly different on this support and the existing stand structure is or not bearing saddle bore in end cap upper support centre of rotor hole, has become the fixing hole of hollow shaft here.Keyway is arranged on the hole, make it on the end cap and can not rotate so that hollow shaft is fixed on key.And have several trough around the hole, form the passage in the frame shell that turns back after winding wire stretches out from the hollow shaft end.In addition, on the eccentric position on the end cap, have axis hole, by rotating shaft of Bearing Installation, the end that rotating shaft is positioned at the end cap inboard is fixed with gear and the wheel nibbled that is fixed on the metal derby is meshed, the other end that is positioned at end cap outside rotating shaft is installed belt pulley, by this covering device on the end cap external impetus is delivered on the metal derby in the frame shell, (2b 2c) is embedded in together by two-section respectively and constitutes as the metal derby of rotor major part.One section slightly long (comprising axis hole) makes with nonmagnetic substance (as brass).The high-strength permanent magnet of another section usefulness is made.And the weight of adjustment axis hole both sides, make it rotating torque and balance each other.Two metal derby end institute carrying magnetics are opposite, and promptly one is the N utmost point, and one is the S utmost point.One of them metal derby both sides has boss, a side to be used to install the roller gear that is meshed with power input gear around axis hole, and opposite side is used to install the bevel gear that drives another metal derby.Another metal derby has boss around only in a side shaft hole, is used to install bevel gear, with two metal derby bevel gears relatively by Bearing Installation on hollow shaft, and bevel gear separately is meshed with intermediary's bevel gear on being installed in hollow shaft.The gear shaft of mesomerism gear both can be installed on the cylindrical shell of support, also can be installed on the hollow shaft.More convenient, reliable way also is mounted on the hollow shaft.Promptly make a call to a cross-drilled hole perpendicular to hollow shaft, in this hole, pass the mesomerism gear axle, two intermediary wheels are installed in the hollow shaft both sides at the middle part of hollow shaft.
Whole assembly program of the present invention is that intermediary wheel at first is installed, and the rotation metal derby of mounting strap magnetic pole then is at hollow shaft two ends fixed coil bracing frame then, and on bracing frame coiling.The concrete winding of pitch of the laps is the occupied space of encirclement rotor revolution of radiation-like on the framework that hollow axis hole and bracing frame form, and each circle of coiled is the basket coil by hollow shaft all.Coil is after finishing, with being installed, all-in-one-piece rotor and coil pack in the cylindrical shell of support, mounting base end cap then, and at fixation hollow axle on the end cap and by powered drive wheel and power transmission shaft on the side end cap rotates outer transmission of power two in the casing on the metal derbies.The line end that will produce the coil of voltage at last is fixed on the binding post of support, and the present invention promptly accuses and finishes.
Claims (1)
1, a kind of split pole type DC generator comprises support (1), rotor (2), and power coil (3) is characterized in that:
A, said rotor are by the hollow shaft (2a) that is fixed on the support, two are through on the hollow shaft and can rotate metal derby (2b relative to hollow shaft, 2c) and can drive the counter-rotational bevel gear group of another metal derby (2d) by the rotation of a metal derby and constitute, and wherein an end of one (rotation is the center) has S utmost point magnetic in two metal derbies, one end of another piece has N utmost point magnetic
B, said power coil are on a coil holder (4) that is fixed on the hollow shaft, and are all to pass the birdcage coil that hollow axis hole surrounds the occupied cylindrical space of rotor revolution radially with an every circle of lead.
