Description
【Technical field】
The invention belongs to technical field of mechanical transmission, more particularly to a kind of permanent magnetism current vortex tune based on conjugation feedback magnet rotor
Fast device.
【Background technology】
The ultimate principle of existing permanent magnet coupling device is all using the relative motion between conductor rotor and p-m rotor
Magnetic field of volution is induced in conductor rotor, and the magnetic field of volution attempts the motion for hindering permanent magnetic field, so as to dragged.Using this
Mechanism is planted, power from power side is passed to load-side in a non-contact manner.Its theoretical foundation is classical and known, and principle is tested
The method of card or model machine are also various, simple, but the engineer applied of maturation is still few in number so far.
First kind permanent-magnet speed governor is plate-like, adjusts the distance between conductor rotor and p-m rotor, that is, adjust air gap big
Little, air gap is big, and the moment of torsion of transmission is little, and slippage becomes big, shows as load speed reduction, and vice versa.Announce within 2 25th, 2004
Chinese invention patent announce No. CN1140042C disclose a kind of first kind adjustable magnetic coupler；On January 23rd, 2013
The Chinese utility model patent bulletin CN 202696418U of bulletin discloses the magnetic that a kind of first kind possesses speed-regulating function
Bonder.
And Equations of The Second Kind permanent-magnet speed governor is tubular.It is then to be engaged by adjusting the magnetic field between p-m rotor and conductor rotor
Area, realizes the transmission that power from power side is passed to load-side, and area of contact is big, then the moment of torsion for transmitting is big, and slippage diminishes, table
Now high for load speed, vice versa.Chinese Patent Application No. is 200920256058.7, and Authorization Notice No. is
CN201577019U, authorized announcement date are that the patent of on 09 08th, 2010 discloses a kind of permanent-magnet speed governor, be Equations of The Second Kind forever
Magnetic speed regulator.It includes：Tubular conductor rotor, tubular p-m rotor and actuator, tubular p-m rotor is in tubular conductor rotor
Interior, and the rotary shaft with each self installation independently rotates, actuator adjusts tubular p-m rotor with tubular conductor rotor in axis side
To relative position, thus it is possible to vary the active area between tubular conductor rotor and tubular p-m rotor, realize change tubular lead
The size of torque is transmitted between body rotor and tubular p-m rotor.
In prior art, above-mentioned patent has the drawback that, is all that the design to magnetic circuit still has some deficits, to magnetic energy utilization
Less efficient, and ferromagnetic material is provided with conductor rotor, cause useless heat loss to increase.The above-mentioned first kind and Equations of The Second Kind are forever
Magnetic speed regulator is provided with radiator, does not but take the measure for eliminating or reducing useless heat loss.In view of as described above, the present invention
203056817 U of Authorization Notice No. CN of people, apply for that the patent that the day for announcing is on 07 10th, 2013 discloses a kind of magnet idol
Extremely son and the permanent magnet coupling device based on the magnet dipole, it is proposed that the solution that a kind of magnetic field is set up, but the patent is not
It is related to the regulative mode to magnetic field, and the magnetic field of the dynamic useful effect during permanent-magnet speed governor is needed to rotation is adjusted, and relates to
And technology then increasingly complex.For one of the design of permanent-magnet speed governor, its core technology are using more reasonably machinery knot
Structure realizes the foundation in magnetic field and regulative mode, needs more cleverly topological method and with reference to electromagnetism that is feasible and optimizing and machine
Tool structure is allowed to be achieved.
The magnetic field of the above-mentioned first kind and Equations of The Second Kind permanent-magnet speed governor is set up between p-m rotor and conductor rotor, the
Though two class permanent-magnet speed governors are tubular, its magnetic Circuit Design is come down in a continuous line with first kind permanent-magnet speed governor category in fact, that is, this
" mutually feeding type " magnetic structure of inventor's definition, is built such that the mode in magnetic field, unavoidably can turn with conductor in p-m rotor
Powerful permanent magnetic attraction is there is between son.This permanent magnetic attraction is the unfavorable factor to driven machine or loading robotics, in order to
This magnetic attraction is eliminated, the regulative mode of first kind permanent-magnet speed governor is set to a pair of permanent magnetic disks or a pair of conductors disk with contrary
Direction displacement, and make the rotor of motion axial displacement mechanism in the opposite direction be relative complex, such as its arrange
Be uniformly distributed along the circumference on five rotors one group of toggle lever mechanism, and number of parts is more, and difficulty of processing is big, axially takes up room big, anti-evil
The efficiency of bad environment is also drastically reduced.Thereafter, authorized announcement date on December 23rd, 2009, Authorization Notice No. CN201369666Y's
Above-mentioned leverage is improved to pinion and rack by Chinese patent, is truly had progress, but still be there is machining accuracy and is difficult to protect
The defects such as card, installation difficulty and anti-pollution ability.Application publication number CN101997396A, Shen Qing Publication day March 30 in 2011
The Chinese patent of day employs a kind of double-end lead-screw vice mechanism, is only applicable to small-power product, equally exists installation difficulty and resists
The defects such as filthy ability, and as being used for common slightly powerful product, its mechanism can be relatively bulky, to isolation which described
Bearing brings extra duty, and needs to reinforce disk body intensity, or even cannot be real under huge axial magnetic effect
The normal operation of existing product.
Above-mentioned Equations of The Second Kind permanent-magnet speed governor lies dormant bigger defect, and its defect shows high-power or high rotating speed application
When, the factor for producing extraneous vibration is difficult to eliminate.
Additionally, above-mentioned permanent-magnet speed governor, also has deficiency to the design of structure, such as its governor motion is by two groups of angle bearing groups
Into being adjusted by cam mechanism so that the extension length incrementss of outrigger shaft are very big, cause the structure of product more multiple
Miscellaneous, heavy, the driver of governor motion is arranged on the side of product, needs considerably long push-pull bar, and floor space is larger.It is based on
As described above, the present inventor is in publication number 103915972A, the patent of open on 07 09th, 2014 day for announcing discloses one kind
Self-feeding type Permanent Magnet and Electric eddy speed regulating device, but put into practice and find, is a kind of according to product described in the patent application as overload protection type
Enabled production, but its applicable speed adjustable range is relatively small, so restricted application.

And the axial specification of the rotor disk of whole product is greatly reduced, contribute to the length for shortening outrigger shaft, beneficial at a high speed
Operation.
Additionally, simple and reliable shift adjusting machine, not only can reduce production cost, can more mitigate axle load, and make
The length of outrigger shaft is shorter, for permanent-magnet speed governor, because outrigger shaft is heavy load cantilever high speed rotational operation,
The length of outrigger shaft is reduced, is an important progressive measure, contribute to making product suitable for higher rotating speed and more powerful
Use demand, contributes to reducing vibration, improves safety and reliability.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
