Description
Technical field
The invention belongs to permanent-magnet eddy current drive technology field, particularly relate to the fixing coaxial sleeve cartridge type permanent-magnet eddy current speed regulator of a kind of end face.
Background technology
Permanent-magnet eddy current speed regulating device are realized speed governing by the speed discrepancy changing between prime mover and load, and it has energy-conservation, flexible startup, vibration damping, simple in structure, strong adaptability, own loss is little, easy to maintenance, the life-span long and improve the advantages such as work system reliability.Permanent-magnet eddy current speed regulating device are made up of the ring of eddy rotor of making without nonmagnetic electrically conductive material (being generally copper), the permanent magnet rotor that studs with permanent magnet and governor motion three parts.The basic functional principle of permanent-magnet eddy current speed governing is: in the time that permanent magnet rotor and ring of eddy rotor do relative rotary motion each other, cutting magnetic line in the alternating intense magnetic field that ring of eddy rotor produces in permanent magnet rotor, alternating intense magnetic field is responded to generation alternation eddy current in ring of eddy rotor, and then alternation eddy current produces again alternation Induced magnetic field in ring of eddy rotor, stop the relative motion of ring of eddy rotor and permanent magnet rotor, thereby realize torque transfer and the speed governing between prime mover and load.The version of permanent-magnet eddy current speed regulating device mainly contains at present by regulating air gap distance to realize the square position type permanent-magnet eddy current speed regulator of driving torque adjusting and realizing by adjusting coupling area the socket type permanent-magnet eddy current speed regulator that driving torque regulates.Wherein socket type permanent-magnet eddy current speed regulator has that radial structure is small and exquisite, weight is light, it is little to vibrate, permanent magnetic material efficiency is high, shaftless to properity features such as additional forces, the application of succeeding in numerous workplaces.

Below in conjunction with brief description of the drawings operation principle of the present invention and process:
As shown in Figure 1, Figure 2, Figure 3 shows, the coaxial sleeve cartridge type permanent-magnet eddy current speed regulator that end face provided by the invention is fixing, in the course of the work, first motor rotary shaft 11 rotates, motor rotary shaft 11 drives transition axis 3 to rotate by motor axle key 12, transition axis 3 drives fixed rotor body 41 to rotate by transition axle key 33, fixed rotor body 41 drives sliding rotor body 42 to rotate by rotor feather key 43, thereby the permanent magnet layer 5 that makes to be fixed on sliding rotor body 42 is done synchronous rotation with motor rotary shaft 11; And now driven rotor 6 does not rotate, in the time producing relative rotary motion between power rotor 4 and driven rotor 6, due to the opposite polarity directions that magnetizes of adjacent two permanent-magnet blocks 51 on permanent magnet layer 5, the therefore ring of eddy 64 interior formation alternating magnetic field of permanent-magnet block 51 meetings on driven rotor body 61 in permanent magnet layer 5; Because ring of eddy 64 is to be become by conductor material copper, the alternating magnetic field that permanent-magnet block 51 produces can generate the eddy current of alternation in ring of eddy 64, and then this eddy current produces Induced magnetic field again in ring of eddy 64; The stationary magnetic field of the permanent magnet layer 5 of Induced magnetic field and power rotor 4 interacts, and just between two rotors, produces coupling torque, thereby drives driven rotor 6 to do and identical the rotatablely moving of power rotor 4 directions; After this, in driven shaft 69 output torque one timings, between power rotor 4 and driven rotor 6, keep certain speed discrepancy, power rotor 4 is faster than driven rotor 6 rotating speeds all the time, the two remains motion for the relative rotation, thereby maintaining all the time above-mentioned coupling process, between two rotors, reaching the object of transmitting motion-promotion force.
The coaxial sleeve cartridge type permanent-magnet eddy current speed regulator that end face provided by the present invention is fixing, when needs regulate power rotor 4, the moment of torsion transmitting between driven rotor 6, when rotating speed or power, start the buncher 73 in speed adjusting gear 7, buncher 73 drives governor gear 77 to rotate by speed governing axle 76, governor gear 77 drives the speed governing tooth bar 78 that the is engaged with axial translation along transition axis 3, thereby drive 79 translations vertically of speed governing sliding sleeve, the sliding rotor body 42 being connected by active bearings 44 with speed governing sliding sleeve 79 is translation vertically thereupon also, this causes the coupling area of the ring of eddy 64 on permanent magnet layer 5 and the driven rotor 6 on sliding rotor body 42 to change, and then cause the magnetic coupling moment between power rotor 4 and driven rotor 6 to change, rotating speed and the power output of driven shaft 69 change thereupon, in the time that speed governing sliding sleeve 79 moves to the position aligning near middle support plate 46, permanent magnet layer 5 and ring of eddy 64 vertically, the power rotor 4 of speed regulator of the present invention, driven rotor 6 are in complete couple state, as shown in Figure 1, in the time that speed governing sliding sleeve 79 only has the corresponding position of part to motor 1 direction translation, permanent magnet layer 5 and ring of eddy 64, the power rotor 4 of speed regulator of the present invention, driven rotor 6 are in partial coupling state, as shown in Figure 3.
In the course of the work, except the gravity of speed regulator of the present invention self, driven shaft 69 is also likely subject to motive power and the moment of different directions, these effect force and moments pass to driven rotor body 61 through driven shaft 69 and end cap 68, pass to again the solid shaft part 32 of transition axis 3 through driven bearing 63, due between the hollow shaft part 31 of transition axis 3 and motor rotary shaft 11 for there to be the moving of movement clearance to coordinate, so the external force that the solid shaft part 32 of transition axis 3 bears mainly passes to the location bearing 24 being connected with hollow shaft part 31, be passed to the motor front end boss 13 of B35 type motor 1 finally by positioning bearing seat 22 and end face positioning disk 21.
