Description
Technical Field
The invention belongs to the technical field of permanent magnet eddy current transmission, and particularly relates to a permanent magnet coupler capable of changing the position of a magnet and speed.
Background
The permanent magnetic coupler is a novel transmission device for realizing non-contact transmission of force or torque by utilizing magnetic field acting force. The device has the advantages of stable performance, no higher harmonic pollution, no electromagnetic interference and the like.
The motor can be arranged between a motor and a load to realize soft start of the motor, and the motor coil is not burnt out due to overload. In the aspect of materials, neodymium iron boron permanent magnet materials with better performance are adopted as magnetic sources, so that the transmission power is greatly improved. However, the permanent magnetic material with high magnetic energy product has relatively high price, which results in relatively high cost of the permanent magnetic coupler, so that the variable speed disk magnetic coupler needs to be designed and optimized. And a stronger magnetic field is realized by using fewer materials, so that torque as large as possible is transmitted, and the optimal cost performance is realized.
The working principle of the speed-changing disc type permanent magnet coupler is that the structure of a master magnetic rotor and a slave magnetic rotor of the speed-changing disc type permanent magnet magnetic coupler. The active rotor is embedded with permanent magnets, and the permanent magnet material is neodymium iron boron permanent magnet material with high magnetic energy product. The permanent magnets are magnetized axially and N, S poles are arranged alternately. And slotting on the driven rotor, embedding copper strips, and wrapping the edge contact part by using a thin ring copper sheet. The driving rotor and the driven rotor of the coupler are not contacted, and a certain air gap exists. When the motor drives the active rotor to rotate, the copper bar conductor cuts magnetic force lines, closed induction current can be generated on the copper bar conductor, and an induction magnetic field generated by the induction current is mutually coupled with a permanent magnetic field to generate interaction force so as to generate torque. When the air gap size changes, the interaction force of the driving rotor and the driven rotor changes, and as a result, the slip and the transmitted torque change. The air gap is smaller, the air gap magnetic density is increased, the acting force is increased, the slip is smaller, the air gap is increased, the air gap magnetic density is reduced, the acting force is reduced, and the slip is larger. The adjustment of the air gap of the prior art is effected by means of a screw drive.
The prior published patent CN 104242598B-permanent magnet speed regulation, braking or loading device capable of regulating coupling magnetic flux comprises a driving disc which is a permanent magnet coupling disc, a driven disc/braking disc which is a magnetic flux switching type permanent magnet disc, or a magnetic flux switching type permanent magnet disc which is used as the driving disc and is used as the driven disc/braking disc, wherein the permanent magnet coupling disc and the magnetic flux switching type permanent magnet disc are of an air gap magnetic field coupling structure, and the permanent magnet coupling disc and the magnetic flux switching type permanent magnet disc can be mutually interchanged in an installation sequence or are mutually driven discs or are mutually interchanged in inner and outer nested positions. The invention is suitable for the technical fields of coupling transmission and load speed regulation, automatic speed changer, braking and braking, rotary load, cutting off/combining power, motor energy saving, household appliances, sealing pumps, petrochemical industry, wind power generation and the like, and is used as a technical scheme for designing and manufacturing a permanent magnet speed regulator, a speed regulating coupling and automatic speed changer, a braking device, a load/loading device, a centrifugal load speed regulator or clutch or a novel energy-saving household appliance. The above proposal is excessively bulky in structure and relatively complex, thereby indirectly increasing the cost.
The existing variable speed permanent magnet coupler needs to change an air gap by manually disassembling and assembling bolts and gaskets, so that the transmission torque and the output rotating speed are changed, the adjustment workload is large, and the time consumption is high.
