Description

Technical Field

[0001] The utility model relates to a fan blade assembly structure, in particular to an oil-storing fan blade shaft core applied to an oil-containing bearing. Background Art

[0002] In the matching structure of oil-containing bearings and shaft cores, the effective storage and utilization of lubricating oil has always been one of the important factors affecting the service life and performance of bearings. In the traditional oil-containing bearing structure design, the lubricating oil between the bearing and the shaft core usually relies on regular external replenishment, and the lubricating oil cannot be effectively stored for a long time. This leads to insufficient lubrication. Especially after long-term use, the lubricating oil is easily lost or evaporated, which in turn leads to increased friction on the contact surface between the bearing and the shaft core. This not only increases operating noise, but also accelerates bearing wear, affecting the normal operation and service life of the equipment.

[0003] Although existing technologies incorporate lubricant storage designs into some structures, the large contact area between the bearing and the shaft core and the lack of an effective sealed space result in unsatisfactory lubricant storage. Therefore, how to effectively store lubricant within the shaft-bearing mating structure and reduce lubricant loss, thereby improving bearing lubrication performance, reducing friction noise, and extending equipment life, has become a pressing technical challenge in this field. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides an oil storage fan shaft core for an oil-containing bearing. By arranging one or more oil storage grooves on the shaft core, the lubricating oil can be effectively sealed, and a closed lubricating oil storage space is formed between the bearing and the shaft core, which not only reduces the contact area between the shaft core and the bearing, but also realizes the long-term sealing of the lubricating oil.

[0006] A fan blade, the fan blade comprising a main body and blades arranged on the main body;

[0007] The shaft core has one end fixedly assembled with the fan blade, an oil storage tank is provided on the shaft core, a bearing is installed on the outside of the shaft core at a position corresponding to the oil storage tank, the oil storage tank is closed by the bearing, and lubricating oil is stored in the oil storage tank.

[0008] As a preferred technical solution, there is one oil storage tank, and the oil storage tank is arranged around the shaft core, or there are multiple oil storage tanks, and multiple oil storage tanks are arranged around the shaft core.

[0009] As a preferred technical solution, the height of the bearing is greater than the height of the oil storage tank, so that the bearing can completely enclose the oil storage tank.

[0010] As a preferred technical solution, the main body is provided with an assembly hole, the shaft core is installed in the assembly hole, and the shaft core and the assembly end of the assembly hole form an anti-slip assembly section.

[0011] As a preferred technical solution, the anti-slip assembly section is a knurled section.

[0012] As a preferred technical solution, the oil storage tank is an oil storage tank of any regular or irregular shape.

[0013] The beneficial effects of the present invention are as follows: the present invention can effectively seal the lubricating oil by arranging one or more oil storage grooves on the shaft core, forming a closed lubricating oil storage space between the bearing and the shaft core, which not only reduces the contact area between the shaft core and the bearing, but also realizes the long-term sealing of the lubricating oil;

[0014] In addition, the shaft core of the present invention is provided with a knurled section, which can effectively increase the assembly friction with the fan blades to prevent loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 and Figure 2 As shown, the utility model is applied to an oil-containing bearing oil storage fan blade shaft core, comprising a fan blade 1, wherein the fan blade 1 comprises a main body and blades arranged on the main body;

[0023] It also includes a shaft core 5, one end of which is fixedly assembled with the fan blade 1, and an oil storage tank 4 is provided on the shaft core 5. A bearing 6 is installed on the outside of the shaft core 5 at a position corresponding to the oil storage tank 4, and the oil storage tank 4 is closed by the bearing 6. Lubricating oil is stored in the oil storage tank 4. Since the outside of the oil storage tank 4 is sealed by the bearing 6, after the shaft core 5 and the bearing 6 are assembled with each other, the internal lubricating oil can be sealed, which effectively prevents the lubricating oil from leaking out and increases the sealing effect.

[0024] In this embodiment, there is one oil reservoir 4, and the oil reservoir 4 is arranged around the shaft core 5, or there are multiple oil reservoirs 4, and multiple oil reservoirs 4 are arranged around the shaft core 5. In this embodiment, there is preferably one oil reservoir, that is, the oil reservoir 4 is arranged around the shaft core 5, and the external bearing 6 completes the closed oil storage, thereby achieving the purpose of gradually lubricating the bearing 6. Of course, in other embodiments, there can be multiple oil reservoirs 4, which are arranged around the shaft core 5 in an interval shape. Of course, the oil reservoirs can be of any regular or irregular shape.

[0025] In order to increase the sealing performance between the bearing 6 and the oil storage tank 4 , in this embodiment, the height of the bearing 6 is greater than the height of the oil storage tank 4 , so that the bearing 6 can completely seal the oil storage tank 4 .

[0026] Among them, there is an assembly hole 2 on the main body, the shaft core 5 is installed in the assembly hole 2, and the shaft core 5 and the assembly end of the assembly hole 2 form an anti-slip assembly section. Specifically, the anti-slip assembly section is a knurled section 3. By setting the knurled section 3, the assembly fastening force between the shaft core 5 and the bearing 6 can be increased, thereby increasing the friction force and preventing slipping or loosening.

[0027] The utility model can effectively seal the lubricating oil by arranging one or more oil storage grooves on the shaft core, forming a closed lubricating oil storage space between the bearing and the shaft core, which not only reduces the contact area between the shaft core and the bearing, but also realizes the long-term sealing of the lubricating oil;

[0028] In addition, the shaft core of the present invention is provided with a knurled section, which can effectively increase the assembly friction with the fan blades to prevent loosening.

[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
