Abstract
The utility model discloses a speed-adjustable magnetic coupler of a magnet rotor synchronously moved by a left screw thread and a right screw thread. The speed-adjustable magnetic coupler comprises a first magnet rotor (1), a second magnet rotor (2), a first copper rotor (3) and a second copper rotor (3). A first gap (7) is disposed between the first magnet rotor (1) and the first copper rotor (3). A gap (8) is disposed between the second magnet rotor (2) and the second copper rotor (4). The first magnet rotor (1) and the second magnet rotor (2) are respectively provided with a left screw thread (5) and a right screw thread (6), wherein the left screw thread (5) and the right screw thread (6) has the same pitch but different screw thread diameters. An internal and external thread sleeve (9) is arranged between the left screw thread (5) and the right screw thread (6). According to the speed-adjustable magnetic coupler of a magnet rotor synchronously moved by a left screw thread and a right screw thread, when the internal and external thread sleeve is adjusted to rotate by an electric performer and other executing mechanisms, the two magnet rotors can move synchronously toward opposite directions through the internal thread and the external thread of the internal and external thread sleeve, and the gap between the two magnet rotors and the gap between the two copper rotors are basically the same during the adjustment.
Description
Technical field
The utility model relates to and revolves the adjustable speed magnetic coupling of screw thread with the moved further magnet rotor about a kind of.
Background technology
With permanent magnetism power can transfer torque be the technology of common knowledge; 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, by the magnetic line of force of 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, has no mechanical connection between them and gapped, and they are connected with engine, working machine respectively; 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.
The utility model content
The purpose of the utility model provides revolves the adjustable speed magnetic coupling of screw thread with the moved further magnet rotor about a kind of.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: revolve the adjustable speed magnetic coupling of screw thread with the moved further magnet rotor about a kind of; Comprise first magnet rotor (1), second magnet rotor (2), first copper rotor (3) and second copper rotor (4); Be provided with first gap (7) between first magnet rotor (1) and first copper rotor (3); Be provided with gap (8) between second magnet rotor (2) and second copper rotor (4); 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 said first magnet rotor (1), second 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 said internal and external threads cover (9) is corresponding with screw thread on left hand thread cover (5), the right-handed thread cover (6).
When said internal and external threads cover (9) rotates, do in the opposite direction moving axially through left hand thread cover (5) and right-handed thread cover (6) drive first magnet rotor (1), second magnet rotor (2) respectively.
Revolve the adjustable speed magnetic coupling of screw thread about the utility model is a kind of with the moved further magnet rotor; When the adjusting of actuators such as YE is rotated the internal and external threads cover; Internal and external threads cover just can make two magnet rotors synchronously move by rightabout through its internal and external screw thread, also will be when regulating two gaps between two magnet rotors and two copper rotors keep basic identical.
