[0028] Referring toFigure 1 And Figure 2 The hub 2 is coaxially provided with a mounting portion 22, the hub 2 is provided with a mounting through hole 221 for mounting the mounting portion 22, the mounting portion 22 and the shaft sleeve 3 are provided with a damping block 4, the mounting portion 22 comprises an inner cavity 222 for accommodating the damping block 4, the damping block 4 is provided with an embedded through hole 41 which is embedded with the shaft sleeve 3. The shaft sleeve 3 is fixed on the hub 2 through the mounting portion 22, and the connection between the shaft sleeve 3 and the mounting portion 22 is separated by the damping block 4. The vibration of the shaft sleeve 3 caused by the motor shaft is not easily fed back to the hub 2 through the damping block 4, which effectively reduces the noise generated during the operation of the wind wheel.

[0029] The damping block 4 is made of rubber material. Rubber has high elasticity and viscoelasticity, which can absorb and consume vibration energy, thereby effectively reducing vibration and noise. In addition, rubber has large elastic deformation and small elastic modulus, which can provide better damping effect when subjected to impact and vibration. Moreover, rubber can maintain stable damping performance under high temperature or low temperature conditions, and has wide application range.

[0030] Referring to Figure 1 And Figure 2 The outer wall of the shaft sleeve 3 is provided with a plurality of embedded grooves 32 and positioning grooves 33. The number of the embedded grooves 32 and the positioning grooves 33 depends on the size of the shaft sleeve 3. In the embodiment, there are fourteen embedded grooves 32 and two positioning grooves 33. The fourteen embedded grooves 32 are arranged in a circumferential array with the axis of the shaft sleeve 3 as the center, and the two positioning grooves 33 are arranged along the length direction of the shaft sleeve 3. The damping block 4 is embedded in the embedded grooves 32 and the positioning grooves 33.

The cooperation of the first damping portion 42, the second damping portion 43, and the damping connecting portions 44 improves the reliability of the damping block 4 fixed on the installation portion 22.

[0034] In the actual manufacturing process, only the installation portion 22 and the shaft sleeve 3 need to be placed in the mold, and then the rubber is injected into the installation portion 22 to complete the assembly of the installation portion 22, the damping block 4, and the shaft sleeve 3.
