Abstract
The invention discloses a speed-adjustable magnetic coupling capable of synchronously moving magnetic rotors through left-hand and right-hand threads, and comprises a magnetic rotor (1), a magnetic rotor (2), a copper rotor (3) and a copper rotor (4), wherein a gap (7) is formed between the magnetic rotor (1) and the copper rotor (3), a gap (8) is formed between the magnetic rotor (2) and the copper rotor (4), a left-hand thread sleeve (5) and a right-hand thread sleeve (6) are arranged on the magnetic rotor (1) and the magnetic rotor (2) respectively and have same pitch and different thread diameters; and an internal/external thread sleeve (9) is arranged between the left-hand thread sleeve (5) and the right-hand thread sleeve (6). According to the speed-adjustable magnetic coupling capable of synchronously moving the magnetic rotors through the left-hand and right-hand threads, when the internal/external thread sleeve is rotated by electrical actuators or other actuating mechanisms, the internal/external thread sleeve drives the two magnetic rotors to synchronously move in opposite directions through the internal and the external threads, so that during adjustment, the two gaps between the two magnetic rotors and the two copper rotors stay substantially the same.
Description
Technical field
The present invention relates to revolve the adjustable speed magnetic coupling of screw thread about a kind of with the moved further magnet rotor.
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 working machine with the transmission of power of engine, and the gap length between them has determined the size of transferring power ability.
Summary of the invention
The purpose of this invention is to provide and revolve the adjustable speed magnetic coupling of screw thread about a kind of with the moved further magnet rotor.
The technical scheme that the present invention is adopted for achieving the above object is: revolve the adjustable speed magnetic coupling of screw thread with the moved further magnet rotor about a kind of, comprise magnet rotor (1), magnet rotor (2), copper rotor (3) and copper rotor (4), be provided with gap (7) between magnet rotor (1) and the copper rotor (3), be provided with gap (8) between magnet rotor (2) and the copper rotor (4), described magnet rotor (1), be respectively equipped with different left hand thread cover (5) of the identical diameter of thread of pitch and right-handed thread cover (6) on the magnet rotor (2), be provided with internal and external threads cover (9) between left hand thread cover (5) and the right-handed thread cover (6).
Internal and external screw thread on the described internal and external threads cover (9) is corresponding with screw thread on left hand thread cover (5), the right-handed thread cover (6).
When described internal and external threads cover (9) rotates, do opposite the moving axially of direction by left hand thread cover (5) and right-handed thread cover (6) drive magnet rotor (1), magnet rotor (2) respectively.
Revolve the adjustable speed magnetic coupling of screw thread about the present invention is a kind of with the moved further magnet rotor, when the adjusting of actuators such as electric actuator is rotated the internal and external threads cover, the internal and external threads cover just can make two magnet rotors synchronously move by rightabout by its internal and external screw thread, also will be when regulating two gaps between two magnet rotors and two copper rotors keep basic identical.
