Description

Technical Field

[0001] The utility model relates to the technical field of NdFeB magnets, in particular to a NdFeB magnet with a mounting structure for a permanent magnetic coupler. Background Art

[0002] Permanent magnetic coupling is a non-contact coupling that uses permanent magnetic materials to generate magnetic fields to achieve torque transmission. The coupler is usually used to connect the motor and the load. It can transmit torque without physical contact. Its working principle is to use the magnetic force generated by two permanent magnets placed opposite to each other to achieve connection and transmission. Since there is no direct physical contact between them, such a design can reduce wear and extend the service life of the equipment. It can also absorb load shock and reduce vibration to a certain extent. It is a permanent magnetic material with extremely high performance. NdFeB magnets are synthesized from rare earth elements neodymium, iron and boron. Due to their excellent magnetic properties, they are widely used in many fields such as electronics, power machinery, and medical equipment.

[0028] Embodiment 2

[0029] like Figure 2 - Figure 4 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0030] The sliding plate 13 cooperates with the spring 12 to balance and stabilize the sliding rod 11. A fixed plate 14 is fixedly connected to the middle side of the outer side of the sliding rod 11. The upper and lower sides of the fixed plate 14 are rotatably connected to the rotating rod 15. The interiors of the two rotating rods 15 are rotatably connected to the fixed shafts 16. The fixed shafts 16 are the rotation centers of the rotating rods 15. The exteriors of the fixed shafts 16 are fixedly connected to the interior of the output shaft 8. The far sides of the two rotating rods 15 are rotatably connected to the posts 17. The posts 17 slide in the slots 10. The exteriors of the posts 17 are slidably connected to the interior of the slots 10. The rotation of the rotating rod 15 causes the posts 17 to move in the slots 10. Circular grooves 18 are provided on the upper and lower sides of the interior of the output shaft 8. The exteriors of the rotating rods 15 are fixedly connected to the interior of the output shaft 8. The sliding connection is inside the circular groove 18, and the circular groove 18 provides space for the external sliding of the rotating rod 15. A sliding groove 19 is opened on the inner middle side of the output shaft 8. The right side of the sliding rod 11 is fixedly connected to a limit plate 20, and the outer side of the limit plate 20 is slidingly connected to the inside of the sliding groove 19. The sliding groove 19 serves to limit the moving range of the limit plate 20. The left side of the sliding rod 11 is fixedly connected to a pull plate 21, and the pull plate 21 can be used to manually adjust the position of the sliding rod 11. The internal rotation of the rotating frame 4 is connected to a rotating magnetic disk 22, and the left side of the rotating magnetic disk 22 is fixedly connected to a load shaft 23. The external rotation of the load shaft 23 is connected to the inside of the rotating frame 4. The load shaft 23 is a key structure for transmitting mechanical energy to the final load.

[0031] Working steps

[0032] When the permanent magnet rotor 9 needs to be installed, the pull plate 21 can be pulled outward, thereby driving the sliding rod 11 to move. At this time, as the sliding rod 11 moves, the sliding plate 13 moves, thereby compressing the spring 12. As the sliding rod 11 moves, the fixed plate 14 slides, thereby causing the rotating rod 15 to rotate. At this time, as the rotating rod 15 rotates around the fixed axis 16, the clamping column 17 moves, thereby causing the clamping column 17 to retract into the inside of the output shaft 8. At this time, the permanent magnet rotor 9 can be slid inside the output shaft 8, thereby causing the clamping column 17 to align with the inner part of the clamping groove 10. At this time, release the pull plate 21, and the sliding disk 13 and the spring 12 can be reset by the elastic force of the spring 12, so that the rotating rod 15 can be rotated again, and then the clamping column 17 can extend out of the output shaft 8, and then it can be engaged in the clamping slot 10. At this time, the installation of the permanent magnet rotor 9 can be completed, and then the motor 7 can be started, and the output shaft 8 can be driven by the motor 7 to rotate, and then the permanent magnet rotor 9 can be rotated. At this time, the magnetic field between the permanent magnet rotor 9 and the rotating magnetic disk 22 can be used to transmit the torque, so that the rotating magnetic disk 22 can be rotated, and finally the load shaft 23 can be driven to rotate.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
