Description
Technical field
The present invention relates to magnetic gear transmission efficiency fields of measurement, specifically a kind of axial coupling permanent magnet magnetism tooth
Take turns the design method of transmission efficiency testing stand.
Background technique
Compared to traditional mechanical gear, magnetic gear is small etc. excellent with no friction, low noise, vibration in specific occasion
Point is particularly suitable for some specific applications, without lubrication, reduces maintenance, high reliablity is particularly suitable for aviation boat
It, undersea device etc. need high reliability and safeguard the occasion of more new equipment difficulty, exist between input and output and be physically isolated, it is non-
Contact transmission allows to transmit torque, revolving speed to sealing area, especially suitable for high leakproofness, high toxicity, high pollution, height
The occasions such as corrosion can accurately determine the torque capacity that can be transmitted, and have overload protection ability very much.
Although magnetic gear has the advantages that such uniqueness.Before this, because permanent-magnet material magnetic property is very poor, magnetic gear
Performance is barely satisfactory, is not also used widely.
It is found from high-performance rare-earth permanent magnet material rubidium iron boron permanent magnet, uses the magnetic gear performance of rubidium iron boron permanent magnet
On have a qualitative leap, although having used high performance permanent magnetic materials, in the performance of the magnetic gear of radial linear coupling still
It is not able to satisfy the requirement of people, magnetic gear is not widely used still, sets later by changing the mechanism of magnetic gear
Coaxial Radial Coupling driven Design is axial coupled drive arranged side by side, linear coupling is converted into face and the endless entire area in face by meter
Coupling, improves the torque density of magnetic gear, so that transmission performance has obtained the promotion of matter, to introduce axial magnetic-type gear
Concept, permanent magnet gear do not need directly to contact between each other, so mechanical friction is not present, thus eliminate in itself by
In a series of vibrations, abrasion and the noise that mechanical gear contacts with each other and causes the problems such as.
Meanwhile magnetic-type gear input, output two sides it is spatially completely isolated, be mainly characterized in that driving wheel and from
Driving wheel passes through axial magnetic field coupled drive torque between magnetic tooth block, and with fixed peak torque and preferable leakproofness and clearly
The clean preferable advantage of property.
Most of all, axial magnetic-type gear overload capacity is strong, since the transmitting torque of mechanical gear is to pass through the gear teeth
Between mechanical directly contact engagement carry out, when load too high, if being easy to appear gear wheel without corresponding safeguard measure
Tooth fractures and is plastically deformed and damage transmission device；When taking corresponding safeguard measure, transmission mechanism can be made more complicated, no
Convenient for manipulating and safeguarding.
And axial magnetic-type gear transmitting torque is to realize that transmission mechanism exists by the magnetic field force in axial space magnetic field
Under overload situations, it can occur to trackslip relatively between the two magnetic gear teeth of interaction permanent magnet coupling, automatic decoupling realized
Carry protection.
Magnetic gear is a kind of new non-contact formula transmission mechanism, advantage be not only to realize between gear it is complete every
From, eliminate noise, be not required to special maintenance and lubrication, further include low detent torque, overload self-protection function, therefore, in magnetic material
Today that material continues to develop has special requirement, such as the on-off of specialized fluids to many transmission devices in power transmission
It is transmitted with the power of flow control and adjusting, the sample transmitting of vacuum plant and taking-up and precision machinery.
These require that the main body of transmission process loses opposing seal or do not contact relatively, and from the direction of motion, fast
Meet special exercise demand on degree and forms of motion simultaneously.
In transmitting, driving and driven component is not contacted, is relatively isolated the power or torque of many situations, the regional closing of realization,
No leakage；It is the moving displacement of driving and driven component and movement velocity flexibility and reliability, accurate steady.
However the transmission to these particular/special requirements, machine driving are difficult to realize, even if it is real reluctantly to use complicated structure
It now operates normally, also various problems can occur in operational process, lead to poor reliability, low efficiency, stability difference or durability degree
It is low.Additional maintenance and maintenance expense will affect this kind of device normal working hours, in addition insecurity factor also can to environment and
Personal safety brings certain danger.
So many difficulty technical problems present in mechanical transmissioning technology are badly in need of solving under some special occasions: in stone
It is toxic in the industrial production of the industries such as oil, chemical industry, pharmacy, stirring, reaction, the transmission of the special medias such as inflammable, explosive, corrosion
Engineering in, need to carry out reasonable control and adjusting appropriate to the uninterrupted of fluid.
But valve mechanism and other Mechanical course poor structural reliabilities in such system, it is perishable, it is easy to damage, easily let out
Leakage, brings very big unstability and risk to the normal operation of system, and its system complexity is brought much to operation
It is inconvenient.
In war industry, all kinds of battlebuses are in field work or make wartime requirement supply fuel oil, fuel oil make-up system
Control and conveying need stable non-contact Drive.
Aerospace machinery etc. is equipped in space motion, and the control Yu conveying of fluid circulation system and cabin are difficult in cabin
With the transmission device of lubrication.
In nuclear industry engineering, the adjustment, conveying and control of heat exchanger circulating liquid are high temperature gas-cooled in low-temperature nuclear heat supplying pile
The conveying on-off of the nuclear fuel element ball of absorption system and control etc. need sensitive reliable operating mechanism in heap.
Many application places need accurate non-contacting operation in Medical Devices, and realize transmission without friction.
The application of mechanical gear in this regard so is greatly tested, and mechanical by addition auxiliary, the technology of satisfaction is wanted
It asks, but increases cost again, application value is made to fall sharply.
In addition using such as pacemaker can not the frequently Medical Devices of surgical procedure when, non-contact transmission embodies
Its original application value.
In scientific experiment equipment and precision mechanical transmission technology, the investment and taking-up of sample, the movement and displacement of workpiece,
The conveying and transmitting of medium are required to transmission mechanism, are extremely difficult to technical requirements using mechanical seal transmission.
In similar above-mentioned some aspects, non-contact, efficient magnetic gear transmission is needed to want to meet these technologies
The summation market demand.
The development of magnetic gear can solve industrial production, and military engineering, Medical Devices, scientific research and precision machinery pass
Partial technical problems in dynamic, realize the new breakthrough in this field, advance science development and technological progress.
Therefore particularly important for the measurement of transmission efficiency, so that the calculating to magnetic gear driving torque is completed, so that
The performance of magnetic transmission mechanism is more accurate.
