Abstract
The invention discloses a permanent magnet coupling speed regulator. The speed regulator comprises a cylindrical conductor rotor, a cylindrical magnetic isolation housing, a cylindrical permanent magnet rotor and a regulator, wherein the cylindrical magnetic isolation housing is positioned between the cylindrical conductor rotor and the cylindrical permanent magnet rotor; gaps are reserved between the cylindrical magnetic isolation housing and the cylindrical conductor rotor and between the cylindrical magnetic isolation housing and the cylindrical permanent magnet rotor; the cylindrical conductor rotor and the cylindrical permanent magnet rotor independently rotate around rotation axes of the cylindrical conductor rotor and the cylindrical permanent magnet rotor respectively and the axial positions are not changed; and under the action of the regulator, the cylindrical magnetic isolation housing slides along the axial direction, so that the area of an acting magnetic field between the cylindrical permanent magnet rotor and the cylindrical conductor rotor is changed; therefore, load torque and rotation speed are changed.
Description
Technical field
The present invention relates to a kind of speed regulating device, the speed regulator of permanent magnetism coupling specifically.
Background technology
The patent No. is 200910232125.6 patent of invention, has announced a kind of permanent-magnet speed governor.It comprises: tubular conductor rotor, tubular p-m rotor and adjuster is characterized in that: the tubular p-m rotor is separated by air-gap in the tubular conductor rotor therebetween, and with the rotating shaft independent rotation of installing separately; Adjuster adjusting tubular p-m rotor and tubular conductor rotor to change the active area between tubular conductor rotor and the tubular p-m rotor, realize changing the size of transmitting torque between tubular conductor rotor and the tubular p-m rotor at the relative position of axis direction.
The tubular p-m rotor comes and goes when mobile under controller action vertically, and the active area between tubular p-m rotor and the tubular conductor rotor changes.Active area is big, and the moment of torsion of transmission is big, output shaft rotating speed height; The moment of torsion of the little transmission of active area is little, and the output shaft rotating speed is little; Active area is zero, and transfer torque is zero, and tubular p-m rotor and tubular conductor rotor are thrown off fully, and tubular p-m rotor rotating speed is zero, and promptly the output shaft rotating speed is zero.
Above-mentioned adjustable magnetic coupler has following deficiency:
1 complex structure, volume is big, and the installing space position is big.
2 cost height.
Summary of the invention
The purpose of this invention is to provide a kind of than the simpler compactness of above-mentioned permanent-magnet speed governor structure, the labour-saving of speed governing, permanent magnetism coupling speed regulator that reliability is high.
The invention provides a kind of permanent magnetism coupling speed regulator, comprising: tubular conductor rotor, tubular p-m rotor, tubular magnetism shielding hood and adjuster; It is characterized in that: the tubular magnetism shielding hood is between tubular conductor rotor and tubular p-m rotor, and tubular magnetism shielding hood and tubular conductor rotor and tubular p-m rotor are all gapped; Tubular conductor rotor and tubular p-m rotor edge be the rotating shaft independent rotation separately, and axial location is constant; Under the effect of adjuster, the tubular magnetism shielding hood slides vertically.
The tubular conductor rotor is installed on the power shaft, the tubular p-m rotor is installed on the output shaft, when the tubular conductor rotor was rotated, tubular conductor rotor and tubular p-m rotor produced relative motion, and axial location is constant mutually in the relative motion process for tubular conductor rotor and tubular p-m rotor.Permanent magnetic field produces eddy current on the tubular conductor rotor, simultaneously eddy current produces induced field again and interacts with permanent magnetic field, thereby drives the tubular p-m rotor along the direction rotation identical with the tubular conductor rotor, and the result is that transmission of torque with power shaft is to output shaft.
The tubular magnetism shielding hood is installed on the output shaft, between tubular conductor rotor and tubular p-m rotor.The tubular magnetism shielding hood come and go to move under controller action vertically, intercept tubular conductor rotor and tubular p-m rotor over against active area; The area that intercepts is big more, and load torque is more little, and rotating speed is low more; Otherwise, as the same.
Permanent magnetism coupling speed regulator of the present invention is compared with general permanent-magnet speed governor, can bring following beneficial effect:
1 simple in structure, volume is little, the installing space position is little.Because the tubular conductor rotor and the tubular p-m rotor of permanent magnetism coupling speed regulator of the present invention do not have relative motion at axial direction, have so just shortened axial dimension greatly, the installing space position is little, and the operational reliability of motor improves.
2 costs are low.
