Description
Technical field
The utility model relates to a kind of drive technology field, relates in particular to a kind of magnetic drive device.
Background technology
Magnetic driver is a kind of transmission device that proposes in order to solve the intrinsic movable sealing problem of traditional transmission device.At present, magnetic driver is comprised of outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve.Its operation principle is, n arranged by rule magnet (n is even number) be assembled on the inside and outside magnet rotor of magnetic driver, makes magnet part mutually form the magnetic force systems that complete lotus root is closed.To be in heteropole relative when inside and outside two magnetic poles, i.e. angle of displacement Φ between two magnetic poles=0, and this moment, the magnetic energy of magnetic system was minimum; To turn to homopolarity relative when magnetic pole, i.e. angle of displacement Φ between two magnetic poles=2 π/n, and this moment, the magnetic energy of magnetic system was maximum.After removing external force, because the magnetic pole of magnetic system repels mutually, magnetic force will make magnet return to the minimum state of magnetic energy.So magnet produces motion, drive the magnet rotor rotation.Magnetic driver converts dynamic sealing point to the static seal point, thereby has solved the movable sealing problem of middle high-pressure occasion, poisonous occasion and corrosive situations, the fail safe that has improved production process.Yet the strength factor of existing magnetic driver is not good, and decay resistance is lower, has greatly affected the performance of magnetic driver.
In view of this, how designing a kind of magnetic drive device, to promote its decay resistance and resistance to wear, is the problem that the insider needs solution badly.
The utility model content
In prior art, not good this defective of the decay resistance in magnetic drive device and resistance to wear, the utility model provides a kind of magnetic drive device.
According to the utility model, a kind of magnetic drive device is provided, wherein, comprising:
Support;
Power shaft is arranged in described support;
Clutch shaft bearing is arranged between described power shaft and described support;
Outer magnet rotor is fixed in an end of described power shaft;
Interior magnet rotor is arranged at the inboard of described outer magnet rotor with one heart;
The fiber reinforced ceramic separation sleeve is arranged between described outer magnet rotor and described interior magnet rotor;
Output shaft is connected in an end of described interior magnet rotor; And
The second bearing is arranged between described output shaft and described support.
Preferably, described the second bearing is sliding bearing or rolling bearing.
Preferably, described output shaft is made by pottery.
Preferably, described output shaft is made by silicon nitride ceramics or silicon carbide ceramics.
The utility model has the advantages that: adopt silicon nitride ceramics or thyrite to make output shaft, can increase corrosion resistance, and can reduce its magnetic conductivity, in addition, separation sleeve adopts fiber reinforced ceramic to make, and has promoted resistance to wear and the corrosion resistance of separation sleeve.
