Description

Technical Field

[0001] This utility model relates to the field of magnetic flywheels, specifically a magnetic flywheel that facilitates the replacement of magnetic blocks. Background Technology

[0002] A magnetic flywheel is a device that combines magnetic materials with a flywheel structure. A flywheel is a rotating component with a large moment of inertia. The magnetic flywheel, based on this, uses magnetic blocks to generate a magnetic field. Its main function is to achieve energy storage, conversion, and transfer through the interaction of the magnetic field with an external magnetic field or current. The magnetic block is the key component of the magnetic flywheel; it is the source of the magnetic field. The materials of the magnetic block are usually ferrite, neodymium iron boron, etc. Ferrite magnetic blocks are relatively inexpensive and have moderate magnetic properties, making them widely used in some applications where the magnetic field strength requirement is not extremely high, such as ordinary small motors.

[0003] The connection between the magnetic block and the magnetic flywheel is designed to minimize the possibility of loosening or detachment during operation, thereby improving the stability and operating efficiency of the equipment. Existing magnets and magnetic flywheels are designed with an integrated fixed connection. After long-term use, magnets and magnetic flywheels may experience wear, aging, or performance degradation, which will directly affect the overall efficiency and safety of the equipment. In this case, in order to replace damaged parts in a timely manner and reduce production losses caused by equipment failure, it is particularly important to simplify the disassembly and replacement procedures. Therefore, we propose a method to facilitate the replacement of magnetic blocks with magnetic flywheels. Utility Model Content

The limiting ring 16 is used to limit the movement of the limiting ring 15, and the telescopic rod 12 is used to limit the movement of the magnetic tile 2.

[0032] Working principle: When the magnet 9 needs to be replaced, rotating the locking ring 7 separates the locking ring 7 from the mounting ring 3. After the locking ring 7 is removed, the contraction groove 5 between the mounting rings 3 returns to its original state. The mounting ring 3 is then loosened from the magnetic flywheel 1 and the magnetic tile 2, allowing the mounting ring 3 and the magnetic tile 2 to be easily pulled out. When replacing the new magnet 9, rotating the threaded rod 10 on the magnet 9 removes it from the threaded groove 18. At the same time, the sleeve 11 and the telescopic rod 12 move out, and the spring 19 returns to its original state. When installing the new magnet 9, the new... A sleeve 11 and a telescopic rod 12 are attached to the magnetic block 9. The worker presses down the telescopic rods 12 on both sides to place the magnetic block 9 between the two magnetic tiles 2. The threaded rod 10 of the magnetic block 9 is then rotated and inserted into the threaded groove 18 of the corresponding mounting rod 17. The telescopic rods 12 at both ends are then released to ensure tight contact with the two magnetic tiles 2. If a different specification of magnetic block 9 needs to be replaced and the specification of the threaded rod 10 of the magnetic block 9 also needs to be changed, the threaded rod 10 on the magnetic block 9 is first removed from the threaded groove 18, and simultaneously the sleeve 11 and the telescopic rod 12 are removed. Rod 12 is moved out and spring 19 returns to its original state. Remove the screw connecting the threaded hole 8 to the mounting ring 3, pull out the entire mounting rod 17, pass the new mounting rod 17 through the mounting ring 3, and install the threaded hole 8 of the fixing plate 6 onto the mounting ring 3 using screws. Attach the sleeve 11 and telescopic rod 12 to the new magnetic block 9, then thread the threaded rod 10 of the new magnetic block 9 into the threaded groove 18 of the mounting rod 17. Finally, place the mounting ring 3 onto the magnetic flywheel 1, and simultaneously... The distance between the magnetic block 9 and the mounting ring 3 is adjusted by rotating the threaded rod 10 between the two adjacent magnetic tiles 2. At this time, the worker presses the telescopic rods 12 on both sides to adjust and clamp the magnetic block 9 between the two magnetic tiles 2. After the adjustment is completed, the locking nut 14 is tightened to one end of the mounting rod 17. The locking nut 14 and the threaded groove 18 are reverse threads. The locking nut 14 further locks the threaded rod 10 and the threaded groove 18. Then the telescopic rods 12 at both ends are loosened and tightly fitted to the two magnetic tiles 2.
