The reinforcing ribs are divided into an upper layer and a lower layer, the two reinforcing ribs on the upper layer are upper-layer reinforcing ribs, the two reinforcing ribs on the lower layer are lower-layer reinforcing ribs, and the reinforcing ribs symmetrically surround the periphery of the core body. And the upper-layer reinforcing ribs and the lower-layer reinforcing ribs correspond up and down or in a staggered manner. The utility model has the beneficial effects that the product cannot slide in the axial direction and the vertical direction, and the weight is light.

Description

Technical Field

[0001] This utility model relates to a bushing, specifically an aluminum bushing for a wind turbine, and belongs to the field of bushing technology. Background Technology

[0002] The bushing is suitable for household air conditioners, commercial vehicle air conditioners, wind film machines, and blower fans. Currently, most metal shafts are knurled or grooved, which can easily loosen and cause malfunctions when high-torque products are running. Due to the difficulty of processing, shafts generally use a circular hole design. If the nut loosens, the impeller can easily spin idly. Utility Model Content

[0003] The purpose of this invention is to address the defect in the prior art where products are prone to loosening during operation, and to provide a wind turbine aluminum bushing that prevents the product from sliding in either the axial or vertical directions.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an aluminum bushing for a wind turbine, which is installed on a wind turbine mounting frame and used in conjunction with the rotating shaft of a motor; the bushing is fixedly connected to the outer periphery of the wind turbine; it includes a core and reinforcing ribs; the core and reinforcing ribs are an integral structure; the reinforcing ribs surround the outer periphery of the core;

[0005] The core is cylindrical in shape, with a through hole in the middle. The cross-section of the through hole is D-shaped, and the length of the straight side of the D-shaped hole is less than the diameter of the circular through hole. The motor shaft is installed inside the D-shaped hole.

[0006] The reinforcing ribs are arc-shaped, and there are 2-8 reinforcing ribs in total.

[0007] The number of reinforcing ribs is 4, and the 4 reinforcing ribs are divided into 2 layers. The upper layer consists of 2 reinforcing ribs, and the lower layer consists of 2 reinforcing ribs, which are symmetrically arranged around the periphery of the core.

[0008] The upper and lower reinforcing ribs correspond to each other vertically or are staggered.

[0009] Compared with existing technologies, the beneficial effects of this utility model are: the D-shaped hole design in the center of the core ensures more effective fixation to the rotating shaft of the motor, preventing the rotating shaft from spinning freely due to loose screws. The symmetrical arc-shaped design of the reinforcing ribs effectively fixes the product, preventing axial slippage. The double-layered reinforcing ribs strengthen the product, preventing vertical slippage. The overall aluminum alloy design makes it lighter. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0017] Example 1:

[0018] like Figures 1 to 4 As shown, an aluminum bushing for a wind turbine is installed on a wind turbine mounting frame and used in conjunction with a motor rotating shaft (not shown in the figure); the bushing is fixedly connected to the outer periphery of the wind turbine (not shown in the figure); it includes a core 1 and a reinforcing rib 2; the core 1 and the reinforcing rib 2 are an integral structure made of aluminum alloy; the reinforcing rib 2 surrounds the outer periphery of the core 1;

[0019] The core 1 is cylindrical in shape, and the core 1 has a through hole in the middle; the cross-section of the through hole is a D-shaped hole 3, and the length of the straight side 4 of the D-shaped hole 3 is less than the circular diameter of the through hole; the motor rotating shaft (not shown in the figure) is installed in the D-shaped hole 3.

[0020] The reinforcing rib 2 is arc-shaped, and there are 4 reinforcing ribs 2.

[0021] The four reinforcing ribs are divided into two layers: the upper two reinforcing ribs are called upper reinforcing ribs 201, and the lower two reinforcing ribs are called lower reinforcing ribs 202, which are symmetrically surrounding the core.

[0022] The upper reinforcing rib 201 and the lower reinforcing rib 202 are corresponding vertically.

[0023] Example 2:

[0024] The upper reinforcing rib 201 and the lower reinforcing rib 202 are staggered and correspond to each other.

[0025] Same as Example 1.

[0026] The embodiments described above are merely preferred embodiments of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution should be included within the protection scope of this utility model.
