The invention has the advantages of reliable bearing seal, long service life, safe and reliable use and no slipping of a magnetic coupling.
Description
[technical field] the present invention relates to magnetic drives, claims the magnetic coupling technical field again, be the improvement of existing simply-support magnetic drive device, a kind of high-capacity magnetic drive device.
[background technology] magnetic drive device can be realized positive confinement under the nominal situation condition, but under following situation, can leak (seeing " magnetic drive pump most common failure and monitoring "): (1) short-term overload, driver generation slippage: at this moment, prime mover turns round continuously, working machine stops, and magnet produces high temperature under positive counter magnetic field alternation effect, as untimely shutdown, a few minutes can make the overheated demagnetization of magnet, cause the permanent damage of driver; (2) ferromagnetic substance or particle deposition are in interior magnet rotor and separation sleeve gap in the fluid, and make separation sleeve wearing and tearing and magnet of a specified duration demagnetize.In a single day crackle takes place separation sleeve or the mill leakage can bringing on a disaster property consequence.
High-capacity magnetic drive device mainly has problems: (one) bearing is the weak link of magnetic drives.In production practices, because the poor sealing performance of bearing seal makes bearing easy to wear, the bad reason of bearing seal is: can not automatic compensation function after selected seal dirt exclusion capabilities difference and the wearing and tearing in the background technology; (2) lack security reliability: Zhao Kezhong " Drive Technology and equipment " 110 pages: " when transshipping or blocking, then the driving and driven male part of magnetic driver can slippage generation relative motion.Be in the effect of alternating magnetic field; to produce eddy current loss, magnetic hysteresis loss and residual loss; the major part of these losses changes heat energy into and causes that magnet temperature raises; the phenomenon of demagnetizing can appear when surpassing allowable work temperature; as untimely shutdown; a few minutes can make the overheated demagnetization of magnet, cause the permanent damage of driver.", unsafe reason is not install in the background technology overload clutch.
[summary of the invention] the object of the invention is to provide a kind of magnetic drive device slippage (step-out), the high-capacity magnetic drive device of bearing long service life can not occur.
[technical scheme] technical solution of the present invention is as follows:
(a) with upper and lower two bearings supporting, wherein: (a) there is a TB3 Che Shi sealing ring upper bearing (metal) bottom to the internal rotor power transmission shaft, and a gland that is bound up on the base center flange is arranged under the sealing ring, and gland is covered by the fan official who is bound up on the power transmission shaft respectively; There is a TB3 Che Shi sealing ring lower bearing top, and the CZF dust ring is arranged on the sealing ring, and dust ring is contained within the dome, and dome is bound up on the bottom center flange, and a cover that is bound up on the power transmission shaft is arranged on the dome;
(b) device one multiple-piece slipclutch between power shaft and outer steel rotor, clutch moment of torque can equal it or is slightly smaller than the moment of torsion of magnet rotor by adjusting.During when the magnet rotor overload or by card, clutch just skids, and the outer steel rotor does not change, and has avoided the slippage of interior magnet steel rotor.One cover moment of torsion is the 1100Nm magnetic drive device, and its price produces entirely, prevents that accident is very important up to 150,000 yuan, have very high economic worth;
[beneficial effect] be reliable, the long service life of bearing seal (a); (b) safe and reliable, not slippage of magnetic coupling.
[description of drawings] Fig. 1. embodiment of the invention structural representation
