Description
Technical field
The utility model relates to the drive technology field in the mechanical engineering, is the magnetic induction coupler that a kind of noncontact connects.It is mainly used in does not have the drive system that axle seals, do not have leakage, resistant to elevated temperatures magnetic drive pump, magnetic agitation still, magnetic valve and other apparatus.
Background technology
Current no axle envelope, in the transmission device of non-leakage magnetic pump and magnetic agitation still all adopts, the structure that outer magnet rotor is coupled, magnet rotor and outer magnet rotor are by the permanent magnet N utmost point that equates the dipole number promptly, the S utmost point is made alternately, the outer magnet rotor permanent magnet N utmost point is realized transmission with the S utmost point with the interior magnet rotor permanent magnet S utmost point and the extremely corresponding coupling of N, yet the transmission device of this magnetic structure but exists certain limitation on using, because interior magnet rotor contacts with medium in the seal isolation cover, belong to flow passage components, therefore, the working temperature of interior magnet rotor permanent magnet directly was limited by the temperature of flow medium.Current best magnetic material, no matter be " neodymium iron boron (Nd-Fe-B) " permanent magnetic material, or " SmCo (Sm-Co) " permanent magnetic material, its limit name working temperature has only 150 ℃ and 300 ℃ respectively, and in actual use, must consider coefficient of safety again, the actual serviceability temperature of samarium cobalt permanent magnet body generally is limited to below 250 ℃, and the actual serviceability temperature of Nd-Fe-B permanent magnet, because the remanent magnetism temperature coefficient is bigger, generally can only be limited to below 80 ℃.When the temperature that has served as flow medium surpassed the actual serviceability temperature of permanent magnet, these permanent magnetic materials were just incompatible, and the physical property of magnet decays following temperature rising.This is the limitation that current general magnetic force coupling transmission device exists.
Summary of the invention
The utility model provides a kind of cage type driven rotor that adopts strip conductor to form to respond to coupled drive with the driving rotor, overcome the permanent magnet induction formula magnetic drive device that interior magnet rotor permanent magnet is subjected to the restriction of medium temperature and influences in the prior art.
The technical solution of the utility model is: it is formed by driving rotor, driven rotor and seal isolation cover.Drive rotor inner wall along the extremely tight permanent magnet alternately of the N utmost point and S is housed in week, form high-energy magnetic field; Driven rotor is being inlayed the cage type inductor of being made up of some strip conductors in the matrix periphery along wall, when prime mover drives the driving rotor rotation, the strip conductor that drives on epitrochanterian high-energy magnetic field and the driven rotor produces induced current, by counter magnetic field and the driving rotor coupling transfer torque that induced current produced.
Advantage of the present utility model: high temperature resistant, stable drive, noiseless, novel structure are simple, easily manufactured, with low cost, have wide range of applications, the nothing that both can be applied to fluid machineries such as pump class, agitating device is leaked drive system, also can be applicable to other transmission field; Both adapted to transfer torque under hot conditions; Also adapt under low temperature, normal temperature condition and transmit square.
The test that the utility model is applied to leak-free high temperature pump drive system shows, medium temperature up to 300 ℃～450 ℃ the time, revolutional slip is stabilized in about 5%, pump all can move in the standard performance scope reposefully continuously.The utility model both can be applicable to the small-power drive system, also can be applicable to Large-power Driving System.Of the present utility model applying will thoroughly solve the leakage problem of high-temperature pump, high-temperature stirring still,
