Abstract
The invention discloses a two-group magnet-rotor-and-copper-rotor-type magnetic-force coupler. The coupler comprises: two magnet rotors of a magnet rotor (1), a magnet rotor (2) and four copper rotors of a copper rotor (3), a copper rotor (4), a copper rotor (5) and a copper rotor (6). The magnet rotor (1), the copper rotor (3) and the copper rotor (4) form one group. The magnet rotor (2), the copper rotor (5) and the copper rotor (6) form the other group. Compared to the current one group type magnetic-force coupler, the two-group magnet-rotor-and-copper-rotor-type magnetic-force coupler of the invention possesses four (two groups) occasions of cutting lines of magnetic force (places of gaps). In this case, when a swing diameter is the same, other basic structures are the same and a rotating speed is the same, transmission power of the magnetic-force coupler of the invention is at least one time larger than that of the current one-group copper-rotor-and-magnet-rotor-type magnetic-force coupler. The invention is especially suitable for the occasions with the restricted swing diameter or a rotating component possessing a high linear velocity and limited material intensity.
Description
Technical field
The present invention relates to magnetic coupling, relate in particular to a kind of two groups of magnet rotors and copper rotor formula magnetic coupling with permanent magnetism power transfer torque.
Background technology
With permanent magnetism power can transfer torque be the technology of knowing altogether, magnetic coupling is based on the actuated element of a kind of transferring power of this technology, one side of magnetic coupling is the permanent magnet (title magnet rotor) that polarity arranges according to certain rules to be installed and opposite side is equipped with copper dish (title copper rotor), when power drives the copper rotor rotation, the magnetic line of force by copper dish cutting permanent magnet, on the copper dish, produce eddy current, and the magnetic field interaction of the magnetic field of eddy current and permanent magnet makes magnet rotor rotate with copper rotor, gapped between them without any mechanical connection, they respectively with engine, working machine connects, just can give engine with the transmission of power of engine, the occasion of existing magnetic coupling cutting magnetic line (just gapped place) has two (promptly one groups) at most, when the identical and rotating speed of other basic structure is also identical, the tactical diameter of the big more then magnetic coupling of transmitted power that requires is just big more, restricted or revolving part has in limited time because of the linear velocity high strength of materials at tactical diameter, and the magnetic coupling of one group of magnet rotor and copper rotor formula just can't be implemented.
Summary of the invention
The purpose of this invention is to provide a kind of transmitted power that makes and increase twice two groups of magnet rotors and copper rotor formula magnetic coupling.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of two groups of magnet rotors and copper rotor formula magnetic coupling, it is characterized in that: comprise magnet rotor (1), (2) two magnet rotors of magnet rotor and copper rotor (3), copper rotor (4), copper rotor (5), (6) four copper rotors of copper rotor, described magnet rotor (1) forms one group with copper rotor (3), copper rotor (4), and described magnet rotor (2) forms another group with copper rotor (5), copper rotor (6).
Be respectively equipped with gap (7) and gap (8) between described magnet rotor (1) and copper rotor (3), the copper rotor (4), be respectively equipped with gap (9) and gap (10) between described magnet rotor (2) and copper rotor (5), the copper rotor (6).
During rotation, the magnetic line of force of the copper dish of described copper rotor (3) and copper rotor (4) cutting magnet rotor (1), the magnetic line of force of the copper dish cutting magnet rotor (2) of described copper rotor (5) and copper rotor (6).
A kind of two groups of magnet rotors of the present invention and copper rotor formula magnetic coupling, what be different from existing one group of formula magnetic coupling is that the occasion (just gapped place) of cutting magnetic line has four (promptly two groups), like this, tactical diameter is identical, other basic structure is identical, transmitted power magnetic coupling when rotating speed is identical will be twice at least than the transmitted power of the magnetic coupling of existing one group of copper rotor and magnet rotor formula, is specially adapted to the restricted or revolving part of tactical diameter because of the limited occasion of the linear velocity high strength of materials.
