Problems solved by technology

When the fan blade rotates under the drive of the motor, there will be a "humming" abnormal sound between the motor and the fan blade, which greatly affects the product quality. Therefore, it is urgent to provide a device that can effectively reduce the noise generated by the fan blade operation new metal inserts

Embodiment 1

[0033] Such as image 3 , Figure 4 As shown, a shaft core for a fan blade is used to connect the blade body and the motor drive shaft. The shaft core includes a first connection assembly 100, a second connection piece 200 and a third connection assembly 300. The second connection The component 200 is respectively formed with a first inner cavity 201 and a second inner cavity (not shown) for accommodating the first connecting component 100 and the third connecting component 300 , and the third connecting component 300 is formed with a motor shaft hole 301 . The inner cavity of the second connecting member 200 is divided into a first inner cavity 201 and a second inner cavity by a partition plate 202, and a through hole is formed in the middle of the partition plate.

[0034] Such as Figure 5 , Figure 6 As shown, the first connection assembly 100 includes a first insert 101 and a first shock absorber 102, the first shock absorber 101 is fastened to the first insert 102, an...

Embodiment 2

[0040] Such as Figure 12 , Figure 13As shown, another centrifugal fan blade and the used shaft core are provided, including blades, a bottom plate and a frame. The center of the bottom plate protrudes upwards to form a motor mounting part, and the blades are evenly arranged between the bottom plate and the frame along the circumference. The centrifugal fan blade also includes a shaft core, the shaft core includes a first connection component, a second connection piece and a third connection component, and the second connection piece is formed with a In the first inner cavity and the second inner cavity, a motor shaft hole is formed on the third connecting component, and the shaft core is connected to the motor mounting part by injection molding.

Abstract

The invention provides a shaft core for a fan blade. The shaft core is used for connecting a fan blade body and a motor driving shaft; the shaft core comprises a first connecting assembly, a second connecting assembly and a third connecting assembly; the second connecting assembly is respectively formed into a first internal cavity and a second internal cavity for accommodating the first connecting assembly and the third connecting assembly; and a motor axle hole is formed on the third connecting assembly. According to the shaft core provided by the invention, the vibration caused by rotation of the fan blade when the fan blade rotates can be effectively reduced, thereby the noise caused by rotation of the fan blade can be effectively reduced, and product quality is improved.

Description

technical field [0001] The invention belongs to the field of fan, and in particular relates to a shaft core for a fan blade and a centrifugal fan blade. Background technique [0002] The body of the existing centrifugal fan blade is connected to the output shaft of the motor through a metal insert, and the metal insert is provided with a motor insertion hole for the output shaft of the motor to be inserted, such as figure 1 As shown, the fan blade body generally includes blades, a bottom plate and a frame. The center of the bottom plate protrudes upwards to form a motor mounting part. The blades are evenly arranged between the bottom plate and the frame along the circumference, and the metal insert is connected to the motor mounting part by injection molding. . Existing metal inserts such as figure 2 As shown, it is a cylindrical aluminum block. When the fan blade rotates under the drive of the motor, there will be a "humming" abnormal sound between the motor and the fan...
