Embodiment
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with drawings and the specific embodiments, the utility model is described further.
An embodiment as shown in Figure 1, a kind of permanent torque type permanent magnetic coupling, comprise the wound rotor of power shaft 12, output shaft 3, two p-m rotors be oppositely arranged and two opposing settings, two wound rotors, between two p-m rotors, leave air gap between p-m rotor and wound rotor.
Described power shaft 12 and output shaft 3 are positioned on same axis, and described output shaft 3 is respectively equipped with the spacing ring 5 ensureing wound rotor and p-m rotor minimal air gap in the outside of two wound rotors.
Two p-m rotors are installed according to the mode that magnetic pole is relative, symmetrical configuration, and the rotor field spider 1 by permanent magnet 2 and installation permanent magnet is formed.The permanent magnet pole of the installation on each p-m rotor is even number, and permanent magnet is along the circumferential direction arranged on rotor field spider 1, and N pole, S pole are alternately arranged, permanent magnet magnetic extreme direction and p-m rotor axis being parallel.In two p-m rotors, first p-m rotor is enclosed within described output shaft 3 by bearing 14, and be connected with its power shaft 12 rotated of driving by flange arrangement, second p-m rotor is enclosed within described output shaft 3 by bearing 4, the rotor field spider end of two p-m rotors is rigidly connected by connecting plate 9, ensures synchronous axial system.
Described first wound rotor, the second wound rotor are formed by the rotor field spider 7 of coil 8, iron core 6 and installation iron core, and two wound rotors are arranged on described output shaft 3, can slide along output shaft 3 axial direction.Described iron core 6 is coiled iron core, and be insulation system between sheet, iron core 6 radially has some wire casings, and coil 8, by enamelled wire or sintering line coiling, is embedded in the wire casing of iron core, is a phase winding or the symmetrical polyphase windings connected.Be provided with spring 11 between two wound rotors, the two ends of described spring 11 are connected on first, second wound rotor.
The one side that first, second wound rotor installs iron core and coil is opposing, and the two is equipped with some to electromagnet 10 and armature 13 in relative one side.Described electromagnet 10 and armature 13 are alternately around being arranged on the opposite face of two wound rotors, mounted in pairing mode, if a such as electromagnet is contained on the first wound rotor, the armature corresponding with this electromagnet is then contained in position corresponding with it on the second wound rotor, on two wound rotors, the quantity of electromagnet wants consistent, to ensure the electromagnetic force equilibrium that electromagnet produces.Described electromagnet 10 is connected with the coil outlet of wound rotor.
Operation principle: when prime mover band driven input shaft rotates, p-m rotor produces a rotating magnetic field, winding coil in wound rotor cuts this magnetic field will produce induced current, the effect of electromagnetic force can be subject in the rotating magnetic field having the wound rotor of electric current to produce at permanent magnet and follow p-m rotor and rotate together, realize transmission of torque, when to connect the output shaft torque, of load end be rated value, between wound rotor, the elastic force of spring is equal with suction between electromagnet with armature, reaches a poised state.When load torque becomes large, electric current in wound rotor becomes large thereupon, electromagnet is due to the large suction enhancing of ER effect simultaneously, pitch smaller between two wound rotors, air gap between wound rotor and p-m rotor increases, the magnetic flux density step-down of air-gap field, the Driving Torque that wound rotor produces diminishes thereupon, thus realizes permanent torque output.
