Technical field
The utility model relates to the magnetic coupling that a kind of cam mechanism is regulated the adjustable speed in gap between rotor.
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 the magnetic coupling that a kind of cam mechanism is regulated the adjustable speed in gap between rotor.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of cam mechanism is regulated the magnetic coupling of the adjustable speed in gap between rotor; Comprise copper rotor (1), magnet rotor (2) and output shaft (4); Be provided with gap (3) between copper rotor (1) and the magnet rotor (2); Also be provided with the cam mechanism (5) that is used to regulate magnet rotor (2); Cam mechanism (5) by can axially movable outer cylinder (6) and fixing inner cylinder (7) constitute, said outer cylinder (6) links to each other with magnet rotor (2).
Said outer cylinder (6) is provided with curved groove.
Said inner cylinder (7) is provided with roller.
A kind of cam mechanism of the utility model is regulated the magnetic coupling of the adjustable speed in gap between rotor; The cam mechanism of magnetic coupling is a drum type brake; Have on the cylinder on curved groove, a cylinder roller is arranged; Cylinder is fixed, another cylinder rotates through the control of actuators such as YE and realizes moving axially, and this axially movable cylinder links to each other with magnet rotor, like this when actuators such as YE move magnet rotor with regard to and the copper rotor fixed of axial location between the gap change; Just regulated the output speed of magnetic coupling, this is easily in remote control and control automatically.
Description of drawings
Fig. 1 is the structure chart that a kind of cam mechanism of the utility model is regulated the magnetic coupling of the adjustable speed in gap between rotor.
Among the figure: 1, copper rotor; 2, magnet rotor; 3, gap; 4, output shaft; 5, cam mechanism; 6, outer cylinder; 7, inner cylinder.
Embodiment
As shown in Figure 1; Cam mechanism is regulated the magnetic coupling of the adjustable speed in gap between rotor, comprises copper rotor 1, magnet rotor 2, output shaft 4 and cam mechanism 5, is provided with gap 3 between copper rotor 1 and the magnet rotor 2; Magnet rotor 2 axial locations can be regulated; The axial location of copper rotor 1 is fixed, and gap 3 can change through the axial location that cam mechanism 5 is regulated magnet rotor 2: gap 3 is bigger than the ability of hour magnetic coupling transferring power, and output speed raises; The ability of magnetic coupling transferring power was less when gap 3 was big; Output speed reduces; Cam mechanism 5 is a drum type brake; Have on the outer cylinder 6 on curved groove, the inner cylinder 7 roller is arranged, inner cylinder 7 is fixed, outer cylinder 6 is rotated through the control of actuators such as YE and realized moving axially, and outer cylinder 6 links to each other with magnet rotor 2; Like this when actuators such as YE move magnet rotor 2 just and the gap 3 between the copper rotor 1 change, also just regulated the output speed of magnetic coupling.
