Description
[technical field] the present invention relates to magnetic drives, claims the magnetic coupling technical field again, is the improvement of existing cantilever type, small capacity, bottom entering type magnetic drives, a kind of bottom entering type magnetic transmission device.
[background technique] bottom entering type magnetic transmission device is with solving a kind of structural type that heads into the formula following problems and occur: when (1) stirring shaft cantilever is long, can produce swing, magnet steel rotor and separation sleeve inwall rub in causing, and have shortened service life of equipment; When (2) in the course of reaction solid product being arranged, magnet steel slippage in can causing.
But there is following problems in existing bottom entering type structure: (one) Great Wall company " magnetic transmission application technical progress ": " problem such as the magnetic drives performance is stable inadequately, and the still inner bearing life-span is short, and operation rate is low and restricting the development of magnetic drives.The user reflects that still internal corrosion and solid particle medium are the principal element that causes operation rate low to lubricating condition in the influence of bearing, the still to influence of bearing etc. ".The still inner bearing life-span, short reason was that bearing seal is bad, and the bad reason of bearing seal is: can not automatic compensation function after selected Sealing dirt exclusion capabilities difference and the wearing and tearing in the background technique; (2) lack safety 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 movement.Be in the effect of alternating magnetic field; to produce eddy current loss, 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 technique safety clutch.
It is a kind of safe, reliable that [summary of the invention] the object of the invention is to provide, not slippage of magnetic coupling, and bearing is not easy to wear, the bottom entering type magnetic transmission device of long service life.
[technological scheme] technical solution of the present invention is as follows:
(a) on bottom bearing, install Che Shi TB3 rotating seal ring and CZF dust ring (Cheng Daxian " mechanical design handbook " volume 3.14-304 page or leaf) successively.Wherein: the CZF dust ring is made into the dust ring of rectangular cross-section by low friction, high abrasion, high-intensity polymer T6, has overlap joint mouthful on the ring, and lap-joint's driving fit is tight, relies on the automatic compensating action of the outer O type circle of ring simultaneously, and being adjacent to the surperficial face that prevents dust does not have the gap; TB3 Che Shi sealing is made up of thin lips and teeth shape slip ring+O type circle, and the slip ring crown is bordering on the line contact with contacting of surface of revolution, can significantly reduce the frictional heat that high speed rotating produces.The thick 0.001-0.0025 of slip surface oil film, a lubricate and unlikely being scraped become to be dripped (leakage), the elastic force of O type circle makes the wearing and tearing that are bordering on the line contact sealing face be able to automatic compensation;
(b) device one safety clutch between input shaft and outer steel rotor, described clutch is a multi-plate friction clutch, height closes the device moment of torsion and can it be equaled 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, its price is (Xu Deqin " development and the application of 2000L high-pressure magnetic still ") up to 150,000 yuan, therefore the device safety clutch ensures safety in production, prevents that accident is very important on the magnetic force reactor, has very high economic value.
[beneficial effect] be reliable, the long service life of bearing seal (a); (b) safe and reliable, not slippage of magnetic coupling.
