[0043] Reference Figure 1-4 The lightweight flywheel comprises a flywheel body 1, a pole claw 2, and a counterweight 4; the flywheel body 1 is constructed as

[0044] It has a bearing hole 5 that penetrates along the axial direction of the central axis of the flywheel body 1. The flywheel body 1 is provided with an annular groove 6, which is constructed to be concave along the axial direction of the bearing hole 5. The flywheel body 1 is provided with a plurality of blades, which extend along the axial direction of the central axis of the flywheel body 1. The flywheel body 1 is also provided with a boss 7, and there are two bosses 7, which are symmetrically arranged on the upper end surface of the flywheel body 1, and the two bosses 7 are connected to each other. The boss 7 is provided inside with a mounting groove for mounting the pole claw 2, the steel magnet 3 and the counterweight 4. The blades include a first blade 8 and a second blade 9, the first blade 8 is mounted on the flywheel body 1, and the second blade 9 is mounted on the boss 7. The height of the first blade 8 is greater than the height of the second blade 9. Through the arrangement of the boss 7, the first blade 8 and the second blade 9 are at the same height, which ensures the energy storage efficiency and cooling efficiency when the flywheel rotates, and makes the wind blown out from the flywheel more uniform.

[0045] The mounting groove includes a first mounting groove 10 and a second mounting groove 11 , and the first mounting groove 10 and the second mounting groove 11 are symmetrically arranged.

[0046] The pole claw 2 and the steel magnet 3 are installed in the first installation slot 10, and the counterweight 4 is installed in the second installation slot 11. There are two pole claws 2, which are tightly matched at both ends of the steel magnet 3. Among them, the weight of the counterweight 4 is equal to that of the pole claw 2 and the steel magnet 3.

[0047] The total weight of the flywheel is consistent. The counterweight block 4 is set to keep the flywheel balanced at both ends, so that it is more stable when in use. The bottom of the first installation groove 10 is at least partially concave away from the blade in the direction of the central axis to form a positioning groove 12, and the steel magnet 3 part

[0048] Installed in the positioning groove 12, the flywheel body 1 is also provided with a positioning plate 13, and one end of the steel magnet 3 abuts against the positioning plate 13. The positioning groove 12 can position the steel magnet 3 in the radial and circumferential directions of the flywheel, so that the flywheel

[0049] The steel magnet 3 can remain stable during rotation and will not be misaligned in the first mounting groove 10 to affect the operation of the flywheel. A limiting groove 14 is also provided in the first mounting groove 10, and a protrusion 15 is provided on the pole claw 2 to be inserted into the limiting groove 14.

[0050] The pole claw 2 is positioned.

[0051] The first mounting groove 10 is also provided with an opening 16, through which the pole claw 2 is partially exposed to the outside of the flywheel body 1.

[0052] The opening 16 facilitates the installation of the pole claw 2 .

[0053] A positioning member 17 is provided in the second installation groove 11. The positioning member 17 is configured to be located along the central axis of the second installation groove 11.

[0054] Extending in the axial direction, the counterweight block 4 is provided with a first through hole 18 for inserting the positioning member 17 .

[0055] The lower end surface of the flywheel body 1 is provided with a groove 19 to reduce the weight of the flywheel and the energy required to rotate the flywheel.

[0056] Energy saving.

[0057] The lower end surface of the flywheel body 1 is provided with an arc groove 20. By providing the arc groove 20, the wall thickness of the flywheel can be reduced.

[0058] The wall thickness can be controlled at 2mm, thus meeting the strength requirements of the flywheel and reducing the weight.

[0059] A reinforcing rib 21 is provided on the lower end surface of the flywheel body 1. This ensures the strength of the connection between the flywheel and the motor shaft and improves the use of the flywheel.

[0060] Use life.

[0061] The boss 7 is provided with a plurality of second through holes 22. Through the second through holes 22, the airflow is caused to flow when the flywheel rotates.

[0062] The gas passes through the second through hole 22 to increase the gas flowability of the flywheel, which reduces noise and absorbs the vibration on the flywheel, thereby reducing the impact of the vibration on the flywheel.

[0063] The flywheel body 1 is provided with a first disassembly hole 23 and a second disassembly hole 24.

[0064] The first and second disassembly holes 23 and 24 are respectively disassembly holes penetrating in the axial direction of the central axis of the flywheel body 1; the first disassembly hole 23 and the second disassembly hole 24 are respectively provided with internal threads. Through the provision of the first and second disassembly holes 23 and 24, the magnetic flywheel can be ejected from the crankshaft by screwing in the screws; thereby simplifying the process of disassembling the magnetic flywheel installed on the crankshaft, greatly reducing the difficulty of disassembly.

[0065] The first disassembly hole 23 and the second disassembly hole 24 are both circular holes and are symmetrically arranged.

[0066] The apertures of the unloading holes 24 are of the same size.

[0067] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used.

[0068] It should be understood that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but also includes other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above invention concept.
