Abstract
The utility model discloses a magnetic suspension resistance absorber which comprises shafts, magnetic suspension bearings and a conveyor belt, wherein, at least two shafts are arranged in parallel, the magnetic suspension bearings are arranged at the two ends of the shafts, and the conveyor belt is arranged on the shafts. When being used, the magnetic suspension resistance absorber is evenly paved on a ship body under the ship; when the ship runs, the water flow causes friction force on the conveyor belt so that the conveyor belt drives the shafts to rotate, an outer ring magnet and an inner ring magnet repel mutually and are not contacted and no friction is generated, thereby greatly reducing the resistance of the water flow to the ship body. The utility model greatly reduces the resistance of a water-borne transport and ensures that an overweight water aircraft realizes the water takeoff.
Description
Technical field
The utility model relates to magnetic suspension principle, particularly a kind of magnetic levitation resistance-reducing device that is applicable to heavy amount marine communication means.
Background technology
At present the marine communication means that utilizes ground to imitate principle mainly is to utilize application force and the antagonistic force that produces between the object and the water surface, increases the principle of lift and the very near aircraft of the dried up face of design-calculated.When the aircraft adjoined water surface flies because the dried up face of wing lower surface is very near, can flow downwards when air flow stream is crossed wing, at this moment ground effect vehicle has lift and two kinds of power of buoyancy, and is lift-off and draining two states simultaneously, promptly as aircraft again as the naval vessel.Because ground effect vehicle can fly between the 1-3 rice on the water surface, it is fast to have a speed of a ship or plane, good economy performance, and safe and reliable advantage, the military specialist predicts that following sea might be its world.But the marine communication means that utilizes ground effect principle at present all is faced with load carrying ability and is restricted, and therefore the excessive problem of resistance when taking off on the water is difficult to possess needs under battle conditions.
The utility model content
The purpose of this utility model is at the existing excessive problem of resistance when utilizing marine communication means that principle is imitated on ground to take off, a kind of resistance that reduces marine communication means is provided, thereby improve its speed, be applicable to the magnetic levitation resistance-reducing device of heavy amount marine communication means.
Technical scheme provided by the utility model is: a kind of magnetic levitation resistance-reducing device, and it comprises axle, and magnetic suspension bearing and belt conveyor, its axis have two and arrangement in parallel at least, and magnetic suspension bearing is installed on the two ends of axle, and belt conveyor is mated formation on axle.
Further, magnetic suspension bearing is made up of outer ring magnet, inner ring magnet and bearing seat, and outer ring magnet and inner ring magnet are the ringshaped magnet that polylith magnet articulating forms, and inner ring magnet is fixedly arranged on the two ends of axle, outer ring magnet is set on the inner ring magnet, and is installed on the bearing seat; Outer ring magnet does not contact mutually with inner ring magnet and opposite face has same magnetic pole.
Further, outer ring magnet and inner ring magnet are high magnetic permanent magnet.
Further, belt conveyor is made by nylon silica gel.
The utility model is according to following advantage is arranged: can reduce the resistance of marine communication means greatly, and simple in structure, easily to make, magnetic suspension bearing does not have friction and consumes, the driving efficiency height, long service life, applied widely.

The specific embodiment
As shown in Figure 1, 2, a kind of magnetic levitation resistance-reducing device 1, it comprises the axle 2 of at least two arrangement in parallels, is installed on the magnetic suspension bearing 3 and the nylon silica gel belt conveyor 4 of mating formation on axle 2 at axle 2 two ends; Magnetic suspension bearing 3 is made up of outer ring magnet 5, inner ring magnet 6 and bearing seat 7, the ringshaped magnet of outer ring magnet 5 for forming by 8 high magnetic permanent magnet articulatings, the ringshaped magnet of inner ring magnet 6 for forming by 6 high magnetic permanent magnet articulatings, inner ring magnet 6 is fixedly arranged on the two ends of axle 1, outer ring magnet 5 is placed in outside the inner ring magnet 5, and is installed on the bearing seat 7; Outer ring magnet 5 does not contact mutually with inner ring magnet 6 and opposite face has same magnetic pole.
Embodiment one: be illustrated in figure 3 as the application of magnetic levitation resistance-reducing device 1 on the naval vessel.During use magnetic levitation resistance-reducing device 1 evenly is laid on the hull under the naval vessel water surface 8, its bottom bracket 6 is installed on the hull.When foot, current cause friction force to belt conveyor 3, making belt conveyor 3 drive axle 1 rotates together, because what magnetic levitation resistance-reducing device 1 used is magnetic suspension bearing 2, outer ring magnet 4 does not contact event mutually with the 5 mutual repulsions of inner ring magnet can not produce friction, thereby has significantly reduced the resistance of current to hull.
Embodiment two: be illustrated in figure 4 as the carry-on on the water application of magnetic levitation resistance-reducing device 1.During use magnetic levitation resistance-reducing device 1 evenly is laid on the floating drum under the overwater flight device water surface 8, its bottom bracket 6 is installed on the floating drum.When aircraft travels on the water, current cause friction force to belt conveyor 3, belt conveyor band 3 moving axis 1 are rotated together, because what magnetic levitation resistance-reducing device 1 used is magnetic suspension bearing 2, outer ring magnet 4 does not contact event mutually with the 5 mutual repulsions of inner ring magnet can not produce friction, thereby has significantly reduced the resistance of current to floating drum.Resistance reduces because take off, so utilize magnetic levitation resistance-reducing device 1 to make aircraft realization water takeoff on the heavy water gaging.
