Abstract
The invention discloses a permanent magnet plane gear mechanism. The axis of a small cylindrical wheel is in orthogonal layout with the axis of a big round disc. A plurality of circles of concentric permanent magnet blocks are evenly distributed on the plane of the big round disc. A plurality of circles of permanent magnet blocks which have equal diameters and have the opposite polarity with the permanent magnet blocks on the big round disc are correspondingly and coaxially arranged on the cylindrical surface of the small cylindrical wheel. When the permanent magnet plane gear mechanism works, the positions of the minimum air gaps generated when the permanent magnet blocks on the small cylindrical wheel are meshed with the permanent magnet blocks on the big round disc are mutually aligned. A plurality of permanent magnet blocks on a plurality of sets of meshing pairs participate in meshing and the meshing time is non-synchronous. Therefore, the permanent magnet plane gear mechanism not only improves driving torque, but also improves driving stationarity under the condition of loading. In addition, the same round permanent magnet blocks are adopted in the two permanent magnet gears, the manufacturing difficulty of magnetic pole blocks and the permanent magnet gears is reduced.
Description
Technical field
The present invention relates to a kind of permanent magnet gear transmission mechanism, particularly the permanent-magnet planar gear drive of a kind of power shaft and output shaft quadrature.
Background technology
Permanent magnet gear is to utilize coupled magnetic field to carry out transmission; along with being widely used of high-performance Ne-Fe-B permanent-magnet material; permanent magnet gear progressively draws attention; with traditional mechanical gear, compare, the permanent magnet gear transmission has noncontact, without advantages such as wearing and tearing, non-maintaining, low noise, overload protection and assembly precision are low.But the transmitting torque less, the permanent magnet gear transmission is engaged transmission, interior engaged transmission and rack-and-pinion transmission etc. exceptionally.Their structure is generally torus or the cylinder that adopts the permanent magnet of radially alternating distribution, by there is a natural attraction between the sexes, the two like magnetic poles repel each other effect realizes continuous torque transmission.
The simple cylinder that the tradition permanent magnet gear is comprised of a plurality of pole pairs, as the permanent magnetism straight spur gear, the permanent magnet that only has minority to rely on recently when working gear participates in transmission of torque, and all the other most of permanent magnets do not participate in, and cause transmitting torque less; In order to improve transmitting torque, the novel permanent magnetic gear that multiple many pole pairs mesh has simultaneously appearred in the world in succession, as the magnetic-field modulation-type permanent magnet gear, gerotor type magnetic gear and axial gap type permanent magnet gear etc., the driving torque density of the magnetic gear that these are new is improved, but complex structure, and be all that power shaft and output shaft can only be coaxially or layout in the same way.
In order to realize power shaft and output shaft orthogonal packing, can adopt permanent magnetism Bevel Gear Drive mode, but the processing of taper seat magnetic pole is more difficult, be also noted that the axial location of big or small permanent magnetism conical gear during assembling.The advantages such as the standard machinery face gear is with the engagement of the canine tooth wheel disc of a little common cylinder spur gear and an orthogonal packing, has an assembly precision requirement low, and pinion is simple, but canine tooth wheel disc flank profil complexity.According to the characteristics of common plane gear drive principle and permanent magnet gear, a kind of permanent-magnet planar gear transmission mode of orthogonal packing has been proposed.
Summary of the invention
Novel permanent magnetic face gear mechanism adopts small column wheel and the vertical layout of big disk axis, organizes pole pair more and is distributed in the small column that magnetic conduction mild steel makes and takes turns on the face of cylinder and big disk planar end.Make in order to improve engages magnetic number of pole-pairs deficiency the drawback that transmitting torque is less, adopt the concentric equally distributed permanent magnets of driven pulley big disk floor plan multi-turn, the opposite polarity permanent magnets of corresponding coaxially arranged equal diameter multi-turn on the small column wheel face of cylinder.
A kind of permanent-magnet planar gear mechanism, this permanent-magnet planar gear mechanism adopts small column wheel and the vertical layout of big disk axis, and the small column wheel is driving wheel, and big disk is driven pulley; The concentric equally distributed permanent magnets of driven pulley big disk floor plan multi-turn, the opposite polarity permanent magnets of corresponding coaxially arranged equal diameter multi-turn on the small column wheel face of cylinder.
From improving the driving torque aspect, avoid again the gearratio of many group engagement permanent magnets inconsistent, the permanent magnets of respectively enclosing on driven big disk equidistantly distributes, and the small column wheel respectively encloses permanent magnets spacing difference on the face of cylinder; Wherein, the permanent magnets group spacing of close small column wheel bearing one side equals big disk outmost turns permanent magnets spacing, with the small column wheel permanent magnets group spacing of big disk inner ring permanent magnets engagement, is greater than big disk outmost turns permanent magnets spacing; When two permanent magnet gear engagements, big disk outmost turns permanent magnets equates with small column wheel permanent magnets path of contact speed, the torque maximum of transmission; Larger with the small column wheel permanent magnets spacing of big disk inner ring permanent magnets engagement, the linear velocity of small column wheel permanent magnets is greater than the linear velocity of big disk inner ring permanent magnets, but because its permanent magnets spacing is larger, just guarantee to align at the permanent magnets engagement minimal air gap place of two-wheeled, magnetic force maximum now, other position air gaps are larger, and magnetic force is less, although stagger a little in the permanent magnets position, little on whole moment transmission impact.
Because many group Meshing Pair participate in transmission, and engagement is asynchronous opportunity, has so both improved driving torque, has also improved the transmission stability under the loading condition.Be distributed in the circular permanent magnet block of the magnetic pole piece employing formed objects on the small column wheel face of cylinder and big disk planar end, also reduced the manufacture difficulty of magnetic pole piece and permanent magnet gear.
