Description
[technical field]
The utility model belongs to technical field of mechanical transmission, particularly a kind of Permanent Magnet and Electric eddy speed regulating device based on conjugation feedback magnet rotor.
[background technology]
The general principle of existing permanent magnet coupling device is all utilize the relative motion between conductor rotor and p-m rotor to induce magnetic field of volution in conductor rotor, and the attempt of this magnetic field of volution hinders the motion of permanent magnetic field, thus is dragged.Utilize this mechanism, load-side is passed in a non-contact manner in power from power side.Its theoretical foundation is classical and known, and the method for Proof-Of Principle 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, regulates the distance between conductor rotor and p-m rotor, namely regulates size of gaps, and air gap is large, and the moment of torsion of transmission is little, and slippage becomes large, and show as load speed and reduce, vice versa.The Chinese invention patent announced on February 25th, 2004 is announced No. CN1140042C and is disclosed a kind of first kind adjustable magnetic coupler; The Chinese utility model patent announced on January 23rd, 2013 is announced No. 202696418U, CN and is disclosed the magnetic coupling that a kind of first kind possesses speed-regulating function.
And Equations of The Second Kind permanent-magnet speed governor is tubular.Being then the magnetic field area of contact by regulating between p-m rotor and conductor rotor, realizing the transmission of power from power side being passed to load-side, area of contact is large, then the moment of torsion transmitted is large, and slippage diminishes, and shows as load speed high, and vice versa.Chinese Patent Application No. is 200920256058.7, and Authorization Notice No. is CN201577019U, authorized announcement date be on 09 08th, 2010 patent discloses a kind of permanent-magnet speed governor, be Equations of The Second Kind permanent-magnet speed governor.It comprises: tubular conductor rotor, tubular p-m rotor and adjuster, tubular p-m rotor is in tubular conductor rotor, and independently rotate with the rotating shaft installed separately, adjuster regulates tubular p-m rotor and tubular conductor rotor at the relative position of axis direction, the active area between tubular conductor rotor and tubular p-m rotor can be changed, realize the size changing transmitting torque between tubular conductor rotor and tubular p-m rotor.
In prior art, the shortcoming that above-mentioned patent exists is all still have some deficits to the design of magnetic circuit, lower to the efficiency of magnetic energy utilization, and be provided with ferromagnetic material in conductor rotor, causes useless heat loss to increase.The above-mentioned first kind and Equations of The Second Kind permanent-magnet speed governor are all provided with radiator, but do not take the measure eliminating or reduce useless heat loss.In view of as mentioned above, the Authorization Notice No. CN 203056817U of the present inventor, application the day for announcing be on 07 10th, 2013 patent discloses a kind of magnet dipole and the permanent magnet coupling device based on this magnet dipole, propose the solution that a kind of magnetic field is set up, but this patent does not relate to the regulative mode to magnetic field, and permanent-magnet speed governor needs to regulate the magnetic field of the dynamic useful effect in rotation, the technology related to is then more complicated.For the design of permanent-magnet speed governor, one of its core technology is to adopt more reasonably frame for movement to realize foundation and the regulative mode in magnetic field, needs topological method make it to be achieved in conjunction with feasible and the electromagnetism optimized and frame for movement more cleverly.
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, though Equations of The Second Kind permanent-magnet speed governor is tubular, but its magnetic Circuit Design in fact belongs to first kind permanent-magnet speed governor and coming down in a continuous line, " mutually feeding type " magnetic structure of namely the present inventor's definition, set up the mode in magnetic field like this, unavoidably can there is powerful permanent magnetic attraction between p-m rotor and conductor rotor.This permanent magnetic attraction is the unfavorable factor to driven machine or loading robotics, in order to eliminate this magnetic attraction, the regulative mode of first kind permanent-magnet speed governor is set to a pair permanent magnetic disk or pair of conductors dish with contrary direction displacement, and make the rotor of motion axial displacement mechanism in the opposite direction be relative complex, such as be uniformly distributed along the circumference one group of toggle lever mechanism on its 5th rotor arranged, number of parts is many, difficulty of processing is large, axially take up room large, the usefulness of anti-adverse environment also sharply reduces.Thereafter, authorized announcement date on December 23rd, 2009, the Chinese patent of Authorization Notice No. CN201369666Y, is improved to pinion and rack by above-mentioned leverage, truly have progress, but still there is machining accuracy and be difficult to ensure, difficulty and the defect such as anti-pollution ability are installed.Application publication number CN101997396A, the Chinese patent in March 30 2011 Shen Qing Publication day have employed a kind of double-end lead-screw vice mechanism, be only applicable to small-power product, the defects such as difficulty and anti-pollution ability are installed in same existence, and as common slightly powerful product, its mechanism can be quite heavy, brings extra duty to isolation bearing described in it, and need to be reinforced disk body intensity, even cannot realize the normal operation of product under huge axial magnetic effect.
Above-mentioned Equations of The Second Kind permanent-magnet speed governor lies dormant larger defect, and during the high-power or high rotating speed application now of its defect map, the factor producing extraneous vibration is difficult to eliminate.
In addition, above-mentioned permanent-magnet speed governor, also deficiency is had to the design of structure, such as its governor motion is made up of two groups of angle bearings, relies on cam mechanism to regulate, makes the extension length recruitment of outrigger shaft very large, cause the structure of product comparatively complicated, heavy, the driver of governor motion is arranged on the side of product, and need the pull bar quite grown, floor space is larger.Based on as mentioned above; the present inventor is at publication number 103915972A; what disclose on 07 09th, 2014 day for announcing patent discloses a kind of self-feeding type Permanent Magnet and Electric eddy speed regulating device; but practice finds; a kind of enabled production according to product described in this patent application as overload protection type; but its applicable speed adjustable range is relatively little, so restricted application.
