Abstract
The utility model discloses a clutch type adjustable speed magnetic force coupler, comprising a shaft(6), a magnetic rotor(1) capable of sliding on the shaft freely, a magnetic rotor(2), an axial fixed copper rotor(3) and a copper rotor(4), wherein, one sides of the magnetic rotor(1) capable of sliding on the shaft freely and the magnetic rotor(2) are equipped with brakes(9). When the clutch type adjustable speed magnetic force coupler of the utility model is started, the brakes(9) are loosened firstly, and then the clearances between the magnetic rotors and the copper rotors are adjusted small, so that a power machine can be started in a zero load or a light load manner; after the clutch type adjustable speed magnetic force coupler is started, the clearances between the magnetic rotors and the copper rotors are adjusted small continuously, so that the power transmitting capability of the magnetic force coupler is enhanced; and by adjusting the clearances according to the system requirements, the output rotating speed of the magnetic force coupler also can be adjusted.
Description
Technical field
The utility model relates to a kind of magnetic coupling of clutch type adjustable speed.
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 magnet 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 copper rotor rotate with magnet 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 a kind of magnetic coupling of clutch type adjustable speed.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of magnetic coupling of clutch type adjustable speed; Comprise axle (6); The magnet rotor (1) that can on axle (6), be free to slide, magnet rotor (2); The copper rotor of axial restraint (3), copper rotor (4), said magnet rotor (1) and magnet rotor (2) one sides are equipped with brake (9).
Be provided with gap (7) between said magnet rotor (1) and the copper rotor (3).
Be provided with gap (8) between said magnet rotor (2) and the copper rotor (4).
On the said axle (5) speed adjusting gear (6) is installed.
The magnetic coupling of a kind of clutch type adjustable speed of the utility model during startup, is turned releasing of brake down earlier again with the gap between magnet rotor and the copper rotor, engine can zero load or light-load starting like this; Continue after the startup to turn the gap between magnet rotor and the copper rotor down, the ability of magnetic coupling transferring power just increases again; Its gap is regulated in requirement according to system, and the rotating speed of magnetic coupling output also is adjustable.
Description of drawings
Fig. 1 is the structural representation of the magnetic coupling of a kind of clutch type adjustable speed of the utility model.
Among the figure: 1, magnet rotor; 2, magnet rotor; 3, copper rotor; 4, copper rotor; 5, axle; 6, speed adjusting gear; 7, gap; 8, gap; 9, brake.
Embodiment
As shown in Figure 1, the magnetic coupling of clutch type adjustable speed comprises axle 5; The magnet rotor 1 that can on axle 5, be free to slide, magnet rotor 2, the copper rotor 3 of axial restraint, copper rotor 4, magnet rotor 1 is equipped with brake 9 with magnet rotor 2 one sides; On the axle 5 speed adjusting gear 6 is installed, engine links to each other with magnet rotor 1, magnet rotor 2, and working machine links to each other with copper rotor; Between magnet rotor and the copper rotor gapped 7 with gap 8, gap 7, gap 8 can be enough big, gap 7, gap 8 can change through the axial location of adjusting magnet rotor 1, magnet rotor 2; The ability of magnetic coupling transferring power is almost 0 when gap 7, gap 8 maximums; If install a brake 9 additional in magnet rotor 1, magnet rotor 2 one sides, the rotating speed of magnet rotor 1, magnet rotor 2 just can be 0, and this moment working machine and copper rotor can also under rated speed, rotate; Thereby realized the separation of two end power; During startup, unclamp brake 9 more earlier the gap 7 between magnet rotor 1, magnet rotor 2 and copper rotor 3, the copper rotor 4, gap 8 are turned down, the engine that is connected with magnet rotor 1, magnet rotor 2 like this can zero load or light-load starting; Continue again after the startup to turn the gap 7 between magnet rotor 1, magnet rotor 2 and copper rotor 3, the copper rotor 4, gap 8 down.
Claims (4)
1. the magnetic coupling of a clutch type adjustable speed; Comprise axle (5); The magnet rotor (1) that can on axle (5), be free to slide, magnet rotor (2); The copper rotor of axial restraint (3), copper rotor (4) is characterized in that: said magnet rotor (1) and magnet rotor (2) one sides are equipped with brake (9).
2. the magnetic coupling of a kind of clutch type adjustable speed according to claim 1 is characterized in that: be provided with gap (7) between said magnet rotor (1) and the copper rotor (3).
3. the magnetic coupling of a kind of clutch type adjustable speed according to claim 1 is characterized in that: be provided with gap (8) between said magnet rotor (2) and the copper rotor (4).
