Description
[technical field]
The utility model relates to the mechanical transmissioning technology field, relates in particular to a kind of magnetic driver.
[background technology]
The magnetic drives technology is the basic theories with modern magnetics, uses permanent magnetic material or two like magnetic poles repel each other that electromagnet pole produces, the magneticaction that there is a natural attraction between the sexes, comes a kind of new technology of realizable force or moment non contact transmission.The device of realizing this technology is called magnetic driver, is called again magnetic driver, magnetic coupling, magnetic coupling etc.General, magnetic driver mainly is by inside and outside two magnet steel, produces the purpose that magnetic coupling reaches transmission by internal-external magnetic steel after the motor-driven, it is maximum to be applied in the pump class.Magnetic driver in the existing technology, the torque of its transmission is little, and internal rotor can produce radial load in the transmission when rotating, and causes the excessive compression to bearing, and in addition, the inner and outer rotors gap is less, is difficult for the processing such as is cleaned in its inside.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, provides a kind of torque large, the magnetic driver of stable drive.
The technical solution of the utility model is achieved in that a kind of magnetic driver, and it comprises the power shaft that imports torque into, output shaft, end cap and the magnetic circuit of output torque; Wherein, described power shaft is fixedly connected with end cap, described magnetic circuit comprises external rotor and internal rotor, described external rotor one end is fixedly connected on end cap, be provided with outer rotor magnet on the inwall of described external rotor, position corresponding with described outer rotor magnet on the described internal rotor outer wall is provided with inner rotor magnets; Described output shaft is fixedly connected on the internal rotor center; Described external rotor is provided with a fixture, and described output shaft is located by the fixture on bearing and the external rotor.
In the said structure, be provided with a separation sleeve between described internal rotor and the external rotor.
In the said structure, described internal rotor comprises the first rotation section and the second rotation section, and described the first rotation section is fixedly connected with described output shaft, and described inner rotor magnets circumferentially is arranged at the external peripheral surface of the second rotation section.
In the said structure, described bearing is two, and two bearings is arranged at intervals on the output shaft.
The beneficial effects of the utility model are: the utility model imports torque into by power shaft, external rotor rotates thereupon, be coupled by the magnet on the inner and outer rotors again, driving internal rotor rotates synchronously, owing to realize the location by fixture and bearing between the inner and outer rotors, can reduce the gap between the inner and outer rotors, increase the magnetic force of the coupling between the inner and outer rotors, the torque of its transmission is large.Simultaneously, fixture and output shaft can provide rigid support to internal rotor, to the pressure of bearing, avoid the mechanical wear of bearing excessive compression minimizing bearing, so that this magnetic driver longer service life when reducing the internal rotor rotation; In addition, the separation sleeve that arranges between the inner and outer rotors can effectively with the inner and outer rotors isolation, be conducive to the cleaning of inner and outer rotors.
