Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan technology, and in particular to an oil-impregnated bearing structure and a fan. Background Technology
[0002] Fans with oil-impregnated bearings are widely used in the market, and the amount of oil stored in these bearings directly affects the overall lifespan of the fan. However, the limited oil storage capacity of oil-impregnated bearings in current fans easily leads to a shorter lifespan. Although adding lubricating oil inside the fan frame can improve the fan's lifespan, oil splattering can occur.
[0003] Therefore, how to improve the oil storage capacity of oil-impregnated bearings to extend their service life and prevent oil spillage is an urgent problem to be solved. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an oil-impregnated bearing structure and a fan.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] On the one hand, this utility model provides an oil-impregnated bearing structure, including an oil-impregnated bearing body, a groove provided on the side wall of the oil-impregnated bearing body, and a filler provided in the groove, the filler being made of an oil-absorbing material.
[0007] Furthermore, the groove is arranged circumferentially around the sidewall of the oil-impregnated bearing body.
[0008] Furthermore, the upper end of the oil-impregnated bearing body is provided with the groove.
[0009] Furthermore, the lower end of the oil-impregnated bearing body is provided with the groove.
[0010] Furthermore, the oil-impregnated bearing body is provided with the groove at both its upper and lower ends.
[0011] Furthermore, the filling material is made of cotton-containing material.
[0012] Furthermore, the filling material is made of sponge.
[0013] On the other hand, this utility model also provides a fan, including a fan frame column and the above-mentioned oil-impregnated bearing structure, wherein the fan frame column is provided with a central hole, and the oil-impregnated bearing body is installed in the central hole.
[0014] Furthermore, the side of the filler is positioned to contact the inner wall of the central hole.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] like Figure 1 As shown, this utility model embodiment provides an oil-impregnated bearing structure, including an oil-impregnated bearing body 3. The side wall of the oil-impregnated bearing body 3 is provided with a groove, and a filler 5 is provided in the groove. The filler 5 is made of an oil-absorbing material.
[0028] In practical applications, due to the oil-absorbing properties of the filler 5, it can adsorb and store a large amount of lubricating oil. When the oil-impregnated bearing body 3 consumes lubricating oil during operation, the lubricating oil stored in the filler 5 can be continuously replenished, thereby increasing the oil content of the oil-impregnated bearing body 3 and effectively extending its service life. At the same time, the filler 5 stably adsorbs the lubricating oil, avoiding oil spillage due to centrifugal force and other factors, thus ensuring a clean and stable operating environment for the equipment.
[0029] Furthermore, the filling element 5 is made of cotton-containing material, preferably, the filling element 5 is made of sponge material.
[0030] Cotton-containing materials have good oleophilicity and capillary action, which can effectively absorb and store lubricating oil. In practical applications, natural cotton or specially treated cotton materials can be selected as filler 5, such as sponge material. Sponge material has a porous structure, strong oil absorption capacity and good elasticity, which can adapt to the slight deformation of the oil-impregnated bearing body 3 during operation, ensuring a stable supply of lubricating oil.
[0031] In one embodiment, the oil-impregnated bearing body 3 has a cylindrical structure with a circumferential groove on its side wall. The filler 5 is made of sponge material, cut to fit the shape and size of the groove, and tightly filled within it. The cotton material can continuously absorb and release lubricating oil, maintaining good lubrication between the motor shaft and the oil-impregnated bearing, effectively reducing frictional loss.
[0032] In one embodiment, the oil-impregnated bearing body 3 is also cylindrical, with a groove provided on its upper side wall. The filler 5 is made of sponge material, which is cut into a shape that fits the groove and then filled in.
[0033] In one embodiment, the oil-impregnated bearing body 3 has a groove on its lower end sidewall, and the filler 5 is still made of sponge material.
[0034] In one embodiment, grooves are provided on the upper and lower sidewalls of the oil-impregnated bearing body 3. The depth and width of the grooves at the upper and lower ends may be the same or different. The filler 5 is made of sponge material and is reasonably filled according to the position and characteristics of the grooves. Through the coordinated work of the fillers 5 at both ends, sufficient lubricating oil is continuously provided to the oil-impregnated bearing, which greatly extends the service life of the oil-impregnated bearing and completely eliminates the problem of oil slicking.
[0035] like Figure 1 As shown, this utility model embodiment also provides a fan, including a fan blade 1, a fan frame 2, a shaft core 4, a fan frame column 21 and the above-mentioned oil-impregnated bearing structure. The fan frame column 21 is provided with a central hole, and the oil-impregnated bearing body 3 is installed in the central hole.
[0036] The fan frame 2 serves as the external frame of the fan, supporting and protecting the internal components. The fan blades 1 are mounted on the shaft core 4, and the rotation of the shaft core 4 agitates and transports air. The fan frame column 21 is located at the center of the fan frame 2, and its central hole is used to install the oil-impregnated bearing body 3. During actual assembly, the oil-impregnated bearing body 3 is first smoothly placed into the central hole of the fan frame column 21 to ensure that the oil-impregnated bearing will not loosen or shift during fan operation. The shaft core 4 passes through the inner hole of the oil-impregnated bearing body 3.
[0037] like Figure 1 As shown, in this embodiment, the bottom of the oil-impregnated bearing body 3 is provided with a retaining ring 6, and the upper surface of the retaining ring 6 contacts the bottom of the filler 5 located at the lower end of the oil-impregnated bearing body 3.
[0038] Furthermore, the side of the filler 5 is positioned to contact the inner wall of the central hole. This design ensures that the filler 5 can fully absorb and transfer lubricating oil, allowing the lubricating oil to form an effective lubrication layer between the oil-impregnated bearing body 3 and the inner wall of the central hole. This effectively enhances the lubricating oil transfer efficiency, ensuring continuous and stable lubrication between the oil-impregnated bearing and the shaft core 4, significantly reducing frictional losses between components, and extending the service life of the oil-impregnated bearing structure and the fan.
[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
