Abstract
The utility model relates to a rare-earth magnet coupler which uses a magnetic field force for transmitting power. Rotary tables 3 are provided with magnetic steel 1. The rotary tables are respectively fixed on a prime mover and a rotating shaft 2 of a dragged unit. A baffle 4 is arranged between the prime mover and the dragged unit. The magnetic field force generated between the magnetic steel is used for transmitting the power. Because of the magnetic steels with very high performance are adopted, the utility model has the advantages that the size is reduced, the operation can be more stable and reliable. Because no rigid connection is required, power leakage is avoided during the power transmission towards a closed system. Moreover, the coupler also has an automatic protection function for overload. No maintenance is required, the transmitting efficiency is high, and basically no power is consumed.
Description
The utility model relates to a kind of Rare-Earth Magnetic coupler that utilizes magnetic field force to come transmitted power.
Traditional power transmission, as belt, gear, sprocket wheel, shaft coupling, hydraulic pressure, form such as pneumatic, all need to adopt rigid material prime mover with linked up by pull-over gear, when must to the sealing system in work prime mover transmitted power the time, just exist and how to solve leakage problems, a solution is a form of taking the axle envelope, as water pump, hydraulic motor, but this method is complex process not only, consumed power, but also can not stop seepage, another kind of solution is prime mover and all is enclosed in the system by pull-over gear that as the motor and the compressor of refrigerator, this method has proposed strict requirement to prime mover, increased cost, and made very difficulty of maintenance.
The purpose of this utility model is the defective that overcomes above-mentioned existence, has proposed a kind of Rare-Earth Magnetic coupler, utilizes the powerful magnetic field force of rare earth permanent-magnetic material generation, reaches the purpose of transmitted power.
Technical solution of the present utility model: transferring rotational motion circumferential coupler and end face shape coupler arranged, its structure such as Fig. 1 and shown in Figure 2, be fixed with rotating disk 3 respectively at prime mover and on by the rotating shaft 2 of pull-over gear, be equipped with on the circumference of rotating disk or on the end face some to equally distributed magnet steel 1, magnet steel is pressed the N utmost point and the S utmost point alternately, the number of pole-pairs of the magnet steel on two rotating disks equates, the polar orientations coupling surface, dividing plate 4 is housed at prime mover and between by pull-over gear, it is made with non-magnet material, its shape can be straight line or curve-like, guarantees passing through of the magnetic line of force, has formed magnetic linkage on coupling surface.Owing to the effect of magnetic linkage, the magnetic field force of generation makes by pull-over gear also along with synchronous rotation when prime mover rotates.This coupler not only can transferring rotational motion, as long as change the shape of dividing plate and the arrangement of magnet steel, can also transmit rectilinear motion, reciprocating motion and curvilinear motion.
Accompanying drawing 1,2 is respectively circumferential of the present utility model, end face shape rare earth coupler structure schematic diagram.
Exemplified two kinds of versions, 1 is magnet steel among the figure, the 2nd, and rotating shaft, the 3rd, rotating disk, the 4th, dividing plate, prime mover both can be on the right side among the figure, also can be in the left side.
The utlity model has following advantage: first has adopted high-performance rare-earth permanent magnet material to make magnet steel, its magnetic energy product is 10 times of traditional anoxic body magnet steel, therefore has very high ratio of performance and volume, in addition, rare earth magnetic steel also has extra high coercive force, therefore magnetic property is highly stable, reliable operation, if adopt ferrite or aluminium nickel cobalt to make magnet steel, when coupler transships, meeting degaussing soon, the power that causes coupler to transmit descends, even lost efficacy, because the rare earth resources of China is abundant, may for adopting magnetic soil magnet steel to provide.Second owing to take to utilize magnetic field force to come transmitted power, can fundamentally solve the seepage phenomenon in the closed system, and its transmission efficiency height, lossless substantially.The 3rd traditional power transmits form; when output load transships; tend to damage driving member; even also can damage prime mover with by pull-over gear, the utility model just can be realized overload protection function as long as suitably adjust the size of magnetic field force; in case output load overload; coupler can skid automatically, after overload goes to disappear, can resume work automatically again and does not have damage.
Claims (2)
1, Rare-Earth Magnetic coupler, divide two kinds of circumferential, end face shapes, it is characterized in that in the rotating shaft 2 of prime mover and pull-over gear, fixing rotating disk 3 respectively, be equipped with somely to equally distributed magnet steel 1 on the circumference of rotating disk 3 or on the end face, magnet steel is pressed the N utmost point and the S utmost point alternately, and the number of pole-pairs of the magnet steel on two rotating disks equates, the polar orientations coupling surface is equipped with the dividing plate made from non-magnet material 4 at prime mover and between by pull-over gear.
2, Rare-Earth Magnetic coupler according to claim 1 is characterized in that dividing plate 4 can adopt linearity or curve-like.
