Description
Technical field
The present invention relates to the magnetic drive device field, particularly a kind of magnetic coupling reductor.
Background technology
In the colliery industry, safety in production has risen to the main problem of restriction coal production.The Security Assurance Mechanism of coal mining enterprise is a kind of multifactor, too many levels, dynamic, complicated operational system.Reverse the passive situation of coal enterprise's safety in production, will pay attention to the exploitation of safe practice and equipment, stop unsafe factor from details.
At present the transmission device major part of equipment that use in the colliery is the machine driving that tradition falls behind again, and this transmission device is not pointed in the application of coal production, does not reach the standard of safety of coal mines on a lot of details, and has the drawback such as consume energy, easy to wear.Along with the safety of coal mines problem becomes increasingly conspicuous, for stopping in detail unsafe factor, guarantee Safety of Coal Mine Production, be badly in need of introducing more rational transmission device.Utilize magnetic force to substitute old-fashioned mechanical connection, realize being flexible coupling between motor and the working machine, the application on coal mine equipment there is no precedent.In this case, most of employed mechanical driving devices do not possess specific aim for coal production, and fail safe is relatively poor and have the series of problems such as high energy consumption, low life-span, and this has brought hidden danger all for the safety in production in colliery.
One, because machine driving complex structure when realizing stepless speed regulation, complicated structure has increased workload and the cost safeguarded, then there is the problem of highly energy-consuming in step speed regulation.
Two, during machine driving, by between gear mutually interlock realize rotating, long-term interlock meeting reduces gear life, affects the normal operation of plant equipment.
Three, there are vibrations in traditional machine driving when start and stop, and affects the useful life of other parts.
Four, traditional machine driving is difficult to realize overload protection, has larger potential safety hazard.
Summary of the invention
The objective of the invention is for energy-conserving and environment-protective, increase service life of equipment, reduce operating cost, the spy provides a kind of magnetic coupling reductor.
The invention provides a kind of magnetic coupling reductor, it is characterized in that: described magnetic coupling reductor comprises input module 1, Left-wing Federation's joint 2, connector 3, tooth bar 4, magnet assembly 5, speed governing overcoat 6, roller 7, handlebar 8, output shaft assembly 9, bearing 10, right coupling 11, operating mechanism 12;
Wherein: be connected by magnet assembly 5 between input module 1 and the output shaft assembly 9, Left-wing Federation's joint 2 is connected with input module 1, connector 3 is connected with tooth bar 4, speed governing overcoat 6 is connected connection by roller 7 with the output shaft assembly, output shaft assembly 9 be connected coupling 11 and connect, operating mechanism 12 is connected with output shaft assembly 9, and handlebar 8 is installed on the speed governing overcoat 6, between input module 1 and the output shaft assembly 9 with the adjustable air gap 13 of spacing.
Described input module 1 comprises copper ring 101 and rotor 102, and copper ring 101 is fixed on the rotor 102.
Described output shaft assembly 9 comprises permanent magnet 901 and p-m rotor 902, and permanent magnet 901 is fixed on the p-m rotor 902, and p-m rotor 902 is the aluminum rotor.
The rated slip of described magnetic coupling reductor is 1-4%.
With between the rotor made of steel of copper ring and the aluminum rotor with permanent magnetic material the air gap being arranged, be called air gap, and do not have the mechanical connection of transmitting torque.When electric machine rotation, with producing inducing eddy-current when the magnetic line of force of cutting permanent magnet on the copper ring on the rotor made of steel of copper ring, and the active force between the magnetic field of the magnetic field of inducing eddy-current and permanent magnet has been realized the moment of torsion transmission between motor and the working machine.When air gap reduced, the transmission capacity of magnetic coupling reductor was strong; Transmission capacity was little when on the contrary, air gap was large.And controller can be by size manual or that control signal is regulated air-gap.For automatic control system, when controller is received a control signal, behind the signal of the requirements such as pressure, flow or liquid level being regulated such as system, after controller is identified, is calculated and change signal, send regulating command for its executive component, executive component will be regulated the air gap between copper rotor and the p-m rotor, thereby changes the working point of working machine, has namely regulated rotating speed and the moment of torsion of working machine.
The output torque of magnetic coupling speed reducer transmission device equals input torque and its output speed and input speed are unequal, difference between them and the ratio of input speed are called revolutional slip, rated slip is 1-4%, and transmission device has different speed adjustable ranges for the working machine of different load characteristic.
Advantage of the present invention:
The motor overload protection of at present extensive use roughly has three kinds of thermal relay protection, air switch protection, frequency converter protections etc., and wherein frequency converter is more advanced.The present invention compares with frequency converter, and unique advantage is arranged: stability and reliability ratio frequency converter are high, and be especially outstanding when high-power.Load speed is high, the replacement frequency converter was with the obvious advantage when power was large; Adaptive capacity in abominable operational environment and maintenance-free performance are that frequency converter is not available; Compare with frequency converter, electrical network is not produced humorous wave interference; When lower voltage, frequency converter possibly can't be worked, but the magnetic coupling reductor is then unaffected; Compare with frequency converter, can eliminate the vibrations transmission between motor and the load; Compare with frequency converter, the care and maintenance expense is low; Compare with frequency converter, magnetic coupling deceleration function effectively prolongs the life-span of each parts of drive system; Rely on the adjusting size of gaps to realize stepless time adjustment.So not only can realize stepless time adjustment, and the energy-saving effect highly significant, the different energy-saving effects of realizing up to 66% that speed governing required according to loadtype and system process.Because the present invention is according to electromagnetic principle, there is not the gear engagement, therefore can not affect the normal operation of equipment, the overall operation cost is low.Motor can realize that more steady and progressive flexibility starts and stops, and reduces and impacts and vibrations, effectively prolongs the useful life of each parts in the drive system.Owing between motor and working machine, rely on electromagnetic induction principle to realize " being flexible coupling ", therefore motor is had overload protection function, thereby improved the fail safe of whole system, eliminated the problem of the motor damage that causes because of overload fully.
The present invention has overcome the speed change classification that exists in the existing machinery transmission in application practice, energy consumption is high, cost is high, difficult in maintenance, exist hidden danger, existence to shake and affect the problems such as useful life of other parts without overload protection or overload protection.In actual use, magnetic coupling deceleration function overcomes the problems referred to above to greatest extent, reaches the purpose of safe operation.
