The permanent-magnet eddy-current transmission device has the advantages of being low in cost, simple in structure, low in centering requirements of the input shaft and the output shaft, convenient to install and energy-saving, effectively achieving soft-start and soft-brake, strong in overload protection capability, and long in service life.
Description
Technical field
The utility model relates to a kind of transmission device, particularly a kind of permanent magnetic vortex drive device.
Background technology
The flexible coupling that extensive use is gone up in industry at present comprises drum-shaped tooth type shaft coupling, diaphragm coupling etc.; Though allow under bigger error of centralization condition, to move; But in running, can on motor and bearing axle, produce periodically additional load, running situation is complicated and changeable, in any case the centering of strict guarantee diaxon; Equipment operation all can produce vibration after a period of time, thereby accelerated wear test, shortens equipment life.
Summary of the invention
The purpose of the utility model provides that a kind of cost is low, simple in structure, power shaft and output shaft centering require low, easy for installation, energy-conservation, can realize effectively that soft start callipers brake car, overload protection ability are strong, the permanent magnetic vortex drive device of long service life, overcome the deficiency of prior art.
The permanent magnetic vortex drive device of the utility model has power shaft, and power shaft is connected with copper rotor, is furnished with p-m rotor mutually with copper rotor, and p-m rotor joins with the axle shaft.
The permanent magnetic vortex drive device of the utility model; Wherein said copper rotor comprises rotating frame, at the rotating frame internal fixation annular copper coin is arranged, and described p-m rotor comprises the permanent magnetism flap; On the permanent magnetism flap, be inlaid with several permanent magnets, permanent magnetism flap and copper coin are arranged in parallel.
The permanent magnetic vortex drive device of the utility model; Wherein said copper coin has two; Be located at the inboard of rotating frame respectively and be arranged in parallel; Described p-m rotor is between two copper coins, and the side opening on the described output shaft autorotation frame facet stretches out, and described power shaft is fixedly connected with the another side of rotating frame.
The permanent magnetic vortex drive device of the utility model compared with prior art has following advantage:
Total cost is cheap.Transformation to existing equipment is also very convenient, need not make any change to prior electric machine and power supply; The permanent magnetism worm gearing is installed the back whole system is not produced electromagnetic interference; In most of the cases, close or remove existing process control hardware equipment, load will be carried out under optimized speed, increase energy efficiency, reduce operation and maintenance cost;
Allow the bigger installation error of centralization.The error of centralization that some product allows can reach 5mm, has simplified the process of Installation and Debugging.The ability of permanent magnetic vortex drive device transmission of power and control rate does not receive between motor reel and the bearing axle because the perhaps influence of little skew of low-angle that misalignment is former thereby produce is installed;
Energy-conservation.Through permanent magnetic vortex drive device, input torque always equals output torque, so motor only need produce the needed moment of torsion of load.In different working conditions, power saving rate can reach (25 ~ 66) %;
Soft start/callipers brake car.Use permanent magnetic vortex drive device can reduce the startup power consumption of motor and avoid causing bigger rush of current; Dwindle the capacity of motor; Reduce maintenance workload.The soft start of real band buffering can first starter motor, and then loads, and at utmost reduces the impact to motor and load of motor start-up and brake process;
Overload protection function.The distance-limiting type permanent magnetic vortex drive device widens air gap automatically when the load overload surpasses the moment of torsion of setting, and motor and load are thrown off automatically, and this moment, motor continued then the load stall.When fault was got rid of, system connected automatically, and the protection motor is in order to avoid be damaged;
Simple in structure, can adapt to bad working environment.Long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model has power shaft, and power shaft is connected with copper rotor, is furnished with p-m rotor mutually with copper rotor, and p-m rotor joins with the axle shaft.
As shown in Figure 1: wherein copper rotor comprises the copper rotor mounting panel 4 that is parallel to each other by two; The periphery of two copper rotor mounting panels 4 has through connecting plate 8 and is connected with bolt; Form frame structure; Inboard at each copper rotor mounting panel 4 is connected with annular copper coin 6 through screw, through screw fin 5 is arranged in the outside of copper rotor mounting panel 4.
3 is power shaft, and the right-hand member of power shaft is fixedly connected with the copper rotor mounting panel 4 in left side through bolt, and power shaft 3 has power shaft endoporus 17.The left part outside at power shaft 3 is set with SP2 type bipyramid locking plate, and SP2 type bipyramid locking plate comprises tapered sleeve 1, and there are two bindings 2 that are parallel to each other in tapered sleeve 1 outside, and on the binding 2 fastening bolt is arranged.
12 is output shaft, and the left end of output shaft 12 is fixed with mounting disc 11, and the both sides of mounting disc 11 are connected with two permanent magnetism flaps 9 that are parallel to each other through bolt, and permanent magnetic plate 9 is arranged in parallel with copper coin 6.Be inlaid with several permanent magnets 7 on the permanent magnetic plate 9, and be fixedly clamped through the cover plate 10 that is connected with permanent magnetic plate 9 screw.Permanent magnetic plate 9 was between two copper coins 6 in 2 years.The output shaft hole 16 of output shaft 12 on the copper rotor mounting panel 4 on right side stretches out, and is fixedly connected with connecting axle 13 through bolt, and connecting axle 13 has output shaft hole 14, in the right part outside of connecting axle 13 SP2 type bipyramid locking plate is installed equally.
On output shaft 12, be set with support set 15, be provided with bearing between the permanent magnetism flap 9 on support set 15 and right side and between the output shaft 12.
During installation, the output shaft of drive motors inserts in the input shaft bore 17 in this transmission device also fastening through the SP2 type bipyramid locking plate in the outside.The rotating shaft of working machine is inserted in the output shaft hole 14 in this transmission device also fastening through the SP2 type bipyramid locking plate in the outside.When motor rotated, the magnetic line of force of copper rotor cutting p-m rotor produced inducing eddy-current, makes the magnetic field and the p-m rotor magnetic field interaction of inducing eddy-current, has realized the moment of torsion transmission between motor and the working machine.Do not have mechanical connection between the motor of permanent magnetic vortex drive device and the load, have air gap, motor is connected by original hard (machinery) with load changes soft (magnetic) connection into.
