Abstract
The utility model provides an induction type asynchronous high-temperature magnetic force coupling driver, chiefly comprising a driving shaft, an outer rotor, an outer magnet steel, a separation sleeve, an inner rotor, a copper bar which is arranged on the inner rotor and a copper collar which is connected with the copper bar and a driven shaft. The utility model has the advantages that the induction type asynchronous high-temperature magnetic force coupling driver can normally work under the condition of a variety of operating temperatures and especially the induction type asynchronous high-temperature magnetic force coupling driver is suitable for the transmitting of a variety of high-temperature mediums in the production of chemical industry. The induction type asynchronous high-temperature magnetic force coupling driver, kettle, etc, are combined into transportation and stirring devices without leakage.
Description
Technical field: the utility model relates to the induction type magnetic couple of force and closes transmission device, particularly a kind of Induction Type Asynchronous High-temperature Magnetic Force Coupling Driver.
Background technique: existing induction type magnetic couple of force close driver mainly by motor transmission shaft, external rotor, be located at outer steel, internal rotor on the external rotor, be located on the internal rotor interior magnet steel and in magnet steel circle, separation sleeve and driven shaft constitute.It is applied in need carry out under air-proof condition in the device that medium transfers or stir.This device deficiency in use is that when causing working area high temperature when the medium temperature height that transfers or stir or because of running, the magnet steel in its internal rotor demagnetization can take place and lost efficacy.This is that the Curie temperature of magnetic material is lower, due to the cause of poor heat stability.Present domestic rare earth permanent-magnetic material can only worked below 250 ℃, if operating temperature greater than 250 ℃, this kind transmission device just can not use.
Summary of the invention: the purpose of this utility model is to close the narrow limitation of driver and a kind of improvement driver---the Induction Type Asynchronous High-temperature Magnetic Force Coupling Driver that proposes at existing induction type magnetic couple of force, and it can adapt to various operational temperature conditions.
Can realize the purpose of this utility model by following technical proposals, a kind of Induction Type Asynchronous High-temperature Magnetic Force Coupling Driver, comprise motor transmission shaft, external rotor, be located at outer steel, internal rotor, separation sleeve and driven shaft on the external rotor, it is characterized in that, the copper bar of the axial setting-in correspondence of the outer steel on corresponding external rotor on the internal rotor, the two ends of copper bar are connected with copper ring on the internal rotor sidewall respectively.
The copper bar cross section is rectangular, circle or geometrical shape such as square.
Effect of the present utility model is, 1, it can adapt to various operational temperature conditions, both can work at normal temperatures, also proper functioning at high temperature; 2, cost reduction, favourable competition.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 2 is the A-A place structural drawing in the accompanying drawing 1.
Embodiment: referring to accompanying drawing 1,2, outer steel 1 alternately puts in order by the N utmost point and the S utmost point and is adhesively fixed on the inwall of external rotor 2.External rotor 2 is fixedlyed connected with motor transmission shaft 3.Internal rotor 4 is fixed on driven shaft 5 one ends, the outer steel on the corresponding external rotor 2 of internal rotor 4 circumferential surfacies be provided with corresponding parallel axes to groove, groove is embedded with copper bar 6, copper bar 6 two ends respectively be located at internal rotor 4 two sides on copper ring 10 be connected.Be provided with stainless steel separation sleeve 7 between external rotor 2 and the internal rotor 4, it is fixed on the pump housing or the kettle 8, and their joint is provided with seal ring 9.This driver combines with the pump housing or kettle to form not have to leak and carries or stirring apparatus.The similar squirrel-cage asynchronous motor of its working principle, when promptly outer magnet rotor is changed the line of production living rotating magnetic field at the drive backspin of motor, copper bar on the internal rotor can produce induction current because of cutting magnetic line, the magnetic field interaction that permanent magnet produces on magnetic field that induction current produces and the external rotor makes internal rotor rotate and transmitting torque with external rotor.Because sensed magnetic intensity has a difference with the magnetic intensity of outer magnet rotor on the internal rotor, thus speed discrepancy of inside and outside rotor existence, thereby internal rotor and external rotor are asynchronous rotation.
Claims (2)
