Description
Technical field
The utility model is related to permanent magnet speed regulation device, particularly a kind of many slip tandem type permanent magnet speed regulation devices.
Background technology
Existing permanent magnet speed regulation device is real using Lorentz force produced when mutually being moved between permanent magnet and conductor
Existing motion transmission between engine and working machine.Permanent magnet speed regulation device generally can reconcile to overload and protect with soft start, speed
Protective function, is widely used in by loading in the transmission system constituted with motor.
Existing permanent magnet speed regulation device is typically slip speed governing, i.e., by changing the magnetic flux face between permanent magnet and conductor
Accumulate to adjust rotating speed.When slip is increased, induced current is also increased therewith, and resulting power attenuation is also increased therewith, forever
The caloric value of magnetic arrangements for speed regulation is also increased, when the heat produced by permanent magnet speed regulation device reaches the demagnetization temperature of permanent magnet, forever
Magnet will produce irreversible demagnetization, and now permanent magnet speed regulation device will fail or scrap, therefore existing permanent magnet speed regulation device is passed
The power bracket passed is limited (general during air cooling<500kW).
In addition, using Magna Drive companies of the U.S. as the existing permanent magnet speed regulation device of representative, typically only have two rotors,
Respectively power rotor (being connected with power source) and driven rotor (being connected with load), pass through the axial gas between two rotors of change
Gap length is so as to reach speed governing purpose, and now its axial air-gap magnetic flux governor motion is typically spline pair structure, because
Spline pair when transmitting torque can also axially movable, make to produce between permanent magnet and good conductor it is moving axially relative, to change
Become axial air-gap magnetic flux area and realize speed governing.This mode of speed regulation needs to overcome two kinds of axial forces：One is that air-gap field is produced
The axial component of magnetic pull；Two be along spline pair move when splined shaft and splined hole between frictional force.Spline when being carried due to band
Normal pressure between axle and splined hole is very big, thus make its when moving axially the required frictional force overcome it is also very big, governing system
Larger axial tension is not only needed, and splined shaft is also easy to wear and tear in a short time to scrap.
The content of the invention
To solve the above mentioned problem that prior art is present, the utility model will design a kind of many slip tandem type permanent magnetic speed-adjustings
Device, can solve problems with：
1st, the big slip heating problem of existing permanent magnet speed regulation device；
2nd, axial pull power problems of too during existing air-gap flux governor motion speed governing.

1st, the utility model is made up of multiple single-stage speed adjusting modules, and each single-stage speed adjusting module is only comprising three layers of concentric type
Vertical rotor, is respectively the power rotor being connected with power source, the speed-governing rotor being connected with axial air-gap magnetic flux governor motion, with bearing
Carry the driven rotor being connected；The rotating speed of speed-governing rotor and driven rotor changes, i.e. speed governing with the change of power rotor rotating speed
There is slip between rotor and power rotor, also there is slip between driven rotor and speed-governing rotor；Power rotor, speed-governing rotor and from
Two layers of air gap is formd between dynamic rotor, respectively between power rotor and speed-governing rotor, between speed-governing rotor and driven rotor；
The radial air gap length of this two layers of air gap can be with identical, can also be different, and two slips being consequently formed can be with identical, can also
It is different；Speed-governing rotor is normally at intermediate layer, and its planform is cartridge type, and the cylindrical and bore area of cylinder is respectively mounted permanent magnet；
The inner surface of the power rotor corresponding with speed-governing rotor inner and outer surfaces and the outer surface of driven rotor are then respectively mounted good conductor
(can be copper, aluminium, ferromagnet etc.)；Speed-governing rotor is alternatively conductor layer, and now inside and outside two layers of power rotor and driven rotor be then
Respectively Permanent-magnet layer；

Fast module, by multiple twin-stage speed adjusting modules containing four layers of air gap cascade up in a series arrangement composition one contain more air gaps
Permanent magnet speed regulation device.
Big slip needed for permanent magnet speed regulation device can be decomposed into the small slip containing multiple air gaps by the above method, due to forever
Caloric value very little of the magnetic arrangements for speed regulation under small slip state, even if therefore needed for the input and output end of permanent magnet speed regulation device
Slip it is very big, its overall caloric value also very little will not be too high because of temperature rise with the permanent magnet ensured in permanent magnet speed regulation device
And produce irreversible demagnetization.
2nd, the utility model and Magna Drive companies of the U.S. are unlike the existing permanent magnet speed regulation device of representative：
The permanent magnet speed regulation device of Magna Drive companies only has two rotors, respectively power rotor (being connected with power source) and driven
Rotor (is connected) with load, by changing the axial air-gap length between two rotors so as to reach speed governing purpose, now its axial direction
Air-gap flux governor motion is typically spline pair structure, because spline pair can also be transported vertically when transmitting torque
It is dynamic, make to produce between permanent magnet and good conductor moving axially relative, speed governing is realized to change axial air-gap magnetic flux area.And this reality
With it is new be then three layers of rotor, respectively power rotor, speed-governing rotor and driven rotor, wherein power rotor and power source phase
Connection, speed-governing rotor is connected with axial air-gap magnetic flux governor motion, and driven rotor is connected with load；Because speed-governing rotor only will be actively
The power (rotating speed and torque) of rotor passes to driven rotor, and its role is equivalent to the idle pulley in mechanical gear train, nothing
Power output shaft is needed, therefore also just without necessary spline auxiliary structure in tradition machinery arrangements for speed regulation, when axial air-gap magnetic flux
When governor motion drives the speed-governing rotor in axial direction to move progress speed governing, it is only necessary to overcome the first above-mentioned power (i.e. air-gap field
The axial component of pulling force).

1st, first by taking single-stage speed adjusting module as an example, operation principle of the present utility model is illustrated：
When engine inputs to power rotating speed and torque the outer sleeve 7 in power rotor assembly, outer sleeve 7 produces rotation
Transhipment is dynamic, good conductor B8 is cut the magnetic line of force in speed-governing rotor assembly produced by permanent magnet B4, now good conductor B8 will be produced
The dislike magnetic field consistent with permanent magnet B4 numbers of pole-pairs, makes permanent magnet B4 produce rotary motion and and then make inner sleeve 9 and therein
Permanent magnet A3 produces rotary motion；The rotating excitation field that permanent magnet A3 is produced makes the good conductor A2 in driven rotor assembly cut magnetic force
Line, and the dislike magnetic field consistent with permanent magnet A3 numbers of pole-pairs is produced, produce good conductor A2 consistent with permanent magnet A3 direction of rotation
Rotary motion, and then drive output shaft to produce rotary motion and to output power.
During speed governing, linear motion platform 12 drives joint cover 13 to be moved along output shaft axial direction, and good conductor is changed with this
B8, good conductor A2 and permanent magnet B4 and permanent magnet A3 axial magnetic flux area, produce the output shaft in driven rotor assembly and turn
Speed change, reaches speed governing purpose.
Because good conductor A2 and good conductor B8 needs constantly cutting magnetic line, induced current and induced magnetism could be formed
, therefore the rotating speed of inner sleeve 9 is always less than good conductor B8 rotating speed, the rotating speed of output shaft is always less than the rotating speed of inner sleeve 9,
There is slip characteristic, between speed-governing rotor assembly and driven rotor assembly i.e. between power rotor assembly and speed-governing rotor assembly
With slip characteristic.Slip is bigger, and the rotating speed of output is lower, and produced heat is also bigger.
2nd, secondly operation principle of the present utility model is illustrated by taking twin-stage speed adjusting module 16 as an example：
When the slip needed for the input and output end of permanent magnet speed regulation device is larger, it is double that single-stage speed adjusting module has
Total turn produce that larger heat, i.e. single-stage speed adjusting module be not enough to share needed for permanent magnet speed regulation device during slip structure driven
Single-stage speed adjusting module, composition twin-stage speed adjusting module 16 can be now concatenated together face-to-face by difference；Due to twin-stage speed adjusting module 16
Containing four layers of air gap, therefore thus total slip can share four layers of air gap；By single-stage is compared in the slip that each layer of air gap is shared
Speed adjusting module is small, therefore produced heat is also smaller than single-stage speed adjusting module.
3rd, when the slip needed for the input and output end of permanent magnet speed regulation device is further increased, twin-stage speed adjusting module 16
The four layers of slip transmission being had is not enough to share total slip of permanent magnet speed regulation device, can now go here and there twin-stage speed adjusting module 16
Connection mode, which cascades up, constitutes one containing more air gaps in theory up to infinite many permanent magnet speed regulation devices, makes each layer of air gap
Heat produced by the slip shared in permanent magnet air cooling can be in tolerance range, you can solve permanent magnet speed regulation device
The problem of input heat produced when very big with output end slip is also very big.
The utility model is not limited to the present embodiment, any equivalent concepts in the technical scope that the utility model is disclosed
Or change, it is classified as protection domain of the present utility model.
