Description
Technical Field
[0001] The utility model relates to an oil-containing bearing, in particular to an oil-containing bearing with inner diameter circulating oil storage, belonging to the technical field of bearings. Background Art
[0002] The oil-containing bearing with inner diameter circulating oil storage is one of the essential main components in the production process of fans. When a fan uses an oil-containing bearing with inner diameter circulating oil storage, the oil in the oil storage groove can continuously circulate and lubricate the fan shaft core during rotation, reducing the friction coefficient suffered during the rotation of the fan, so that the fan product has the advantages of no noise, abnormal noise, and high rotation speed during rotation. The quality of the oil-containing bearing with inner diameter circulating oil storage is crucial for the service life of the fan;
[0003] At present, various types of oil-containing bearings have emerged on the market. In the prior art, oil holes are usually opened on the bearing, and then lubricating oil is added before the bearing leaves the factory to achieve the purpose of the bearing containing oil. This kind of oil-containing bearing has only tiny oil holes in the inner diameter and no oil grooves. During the high-speed rotation of the fan, the lubricating oil will overflow from both ends of the inner diameter of the product, which may lead to insufficient lubrication during the high-speed rotation of the fan. Insufficient lubrication of the oil-containing bearing may cause frictional noise and abnormal noise during the rotation of the fan. Moreover, this kind of oil-containing bearing product cannot be circularly lubricated, and the contact surface between the inner wall of the bearing and the fan blade shaft core is relatively large, which may lead to an increase in its friction coefficient and easier heating, thereby greatly reducing the service life of the oil-containing bearing;
[0004] Therefore, it is urgent to improve the oil-containing bearing with inner diameter circulating oil storage to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an oil-containing bearing with inner diameter circulating oil storage, which has several evenly distributed circulating oil storage grooves at the inner diameter. When the fan rotates at a high speed, the fan blade shaft core drives the oil in the inner diameter circulating oil groove to continuously and uninterruptedly circulate and lubricate the fan blade shaft core, ensuring that the inner diameter wall of the inner diameter circulating oil storage bearing and the outer diameter of the fan blade shaft core rotate at a high speed to reduce the friction coefficient and maintain continuous circulating lubrication. The oil groove gap can reduce the contact surface between the inner wall of the bearing and the fan blade shaft core, reduce its friction coefficient and heat generation, thereby effectively reducing the frictional noise and abnormal noise generated during the use of the product, and thus greatly extending the service life of the oil-containing bearing.
[0006] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:
[0007] An oil-containing bearing with an inner diameter circulating oil storage includes an oil-containing bearing body. A number of evenly distributed circulating oil storage grooves are provided at the inner diameter of the oil-containing bearing body. An oil groove gap is provided between the circulating oil storage grooves and the inner wall of the oil-containing bearing body. The circulating oil storage grooves communicate with the inside of the oil-containing bearing body through the oil groove gap. Inner walls and oil storage groove interfaces are fixedly provided on both sides of the oil groove gap, and the inner walls and oil storage groove interfaces are in an arc-shaped structure.
[0008] Preferably, a number of evenly distributed outer diameter exhaust grooves are provided on the outer side of the oil-containing bearing body.
[0009] Preferably, a number of evenly distributed plane exhaust grooves are provided on both plane surfaces of the oil-containing bearing body.
[0010] Preferably, the outer diameter exhaust grooves communicate with the plane exhaust grooves.
[0011] Preferably, the edges of the outer diameter exhaust grooves and the plane exhaust grooves are both in an arc-shaped structure.
[0012] Preferably, on one plane surface of the oil-containing bearing body, the number of the circulating oil storage grooves is equal to the number of the outer diameter exhaust grooves and the plane exhaust grooves, and the three are in one-to-one correspondence.
[0013] Preferably, on one plane surface of the oil-containing bearing body, the outer diameter exhaust grooves communicate with the circulating oil storage grooves.

[0015] Preferably, a convex ring is fixedly provided inside the plane depression, and a number of evenly distributed convex points are fixedly provided outside the convex ring on the plane depression. Both the convex ring and the convex points are provided outside the circulating oil storage grooves.
[0016] Preferably, a number of evenly distributed arc-shaped ribs are fixedly provided inside the plane exhaust grooves.
[0017] The utility model has at least the following beneficial effects:
[0018] 1. There are a number of evenly distributed circulating oil storage grooves at the inner diameter of the utility model. When the fan rotates at a high speed, the oil in the inner diameter circulating oil groove is continuously driven by the wind leaf shaft core to circulate and lubricate the wind leaf shaft core, ensuring that the inner diameter wall of the inner diameter circulating oil storage bearing and the outer diameter of the product wind leaf shaft core rotate at a high speed to reduce the friction coefficient and maintain continuous circulating lubrication. The oil groove gap can reduce the contact surface between the inner wall of the bearing and the wind leaf shaft core, reduce its friction coefficient and heat generation, and thus effectively reduce the friction noise and abnormal noise generated during the use of the product, thereby greatly extending the service life of the oil-containing bearing.

Detailed Description of the Embodiment
[0026] The following will be combined with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.
[0027] As Figures 1 - 5 shown, the oil-impregnated bearing with inner diameter circulating oil storage provided in this embodiment includes an oil-impregnated bearing body 1. The applicable range of the inner diameter size of the oil-impregnated bearing body 1 is between 1 mm and 20 mm, and the applicable range of the outer diameter size is between 4 mm and 40 mm. A number of evenly distributed circulating oil storage tanks 2 are provided at the inner diameter of the oil-impregnated bearing body 1. The applicable range of the number of the circulating oil storage tanks 2 is between 2 and 20 oil grooves. The applicable range of the size of the circulating oil storage tanks 2 is between 0.08 mm and 1.0 mm. An oil tank gap 3 is provided between the circulating oil storage tanks 2 and the inner wall of the oil-impregnated bearing body 1. The applicable range of the width of the oil tank gap 3 is between 0.1 mm and 0.5 mm. The circulating oil storage tanks 2 are connected to the inside of the oil-impregnated bearing body 1 through the oil tank gap 3. Inner wall and oil storage tank interfaces 4 are fixedly provided on both sides of the oil tank gap 3. The inner wall and oil storage tank interfaces 4 are of an arc-shaped structure, and the radius of the inner wall and oil storage tank interfaces 4 is between R0.05 mm and R0.3 mm, which is convenient for the lubricating oil to flow out from the circulating oil storage tanks 2 to the fan shaft core, making the fan rotate more smoothly;
[0028] The circulating oil storage groove 2 at the inner diameter of the oil-impregnated bearing body 1 can increase the oil storage capacity of the oil-impregnated bearing body 1. When the fan rotates at a high speed, the oil in the inner diameter circulating oil groove 2 is continuously driven by the blade shaft core to circulate and lubricate the blade shaft core, ensuring that the inner diameter wall of the inner diameter circulating oil bearing and the outer diameter of the product blade shaft core rotate at a high speed to reduce the friction coefficient and maintain continuous circulating lubrication. The oil groove gap 3 can reduce the contact surface between the inner wall of the bearing and the blade shaft core, reduce its friction coefficient and heat generation, and thus effectively reduce the friction noise and abnormal noise generated during the use of the product, thereby greatly extending the service life of the oil-impregnated bearing.
[0029] Furthermore, as Figures 1 - 5 shown, the outer diameter of the oil-impregnated bearing body 1 is divided into: having an outer diameter exhaust groove 5 and not having an outer diameter exhaust groove 5; the plane of the oil-impregnated bearing body 1 is divided into: having a plane exhaust groove 6 and not having a plane exhaust groove 6; the outer diameter exhaust groove 5 is communicated with the plane exhaust groove 6, and the radii of both the outer diameter exhaust groove 5 and the plane exhaust groove 6 are between R0.2 mm and R1.0 mm, and the applicable range of the length of the plane exhaust groove 6 is between D1 mm and D50 mm; the edges of both the outer diameter exhaust groove 5 and the plane exhaust groove 6 are set as arc-shaped structures; on one side plane of the oil-impregnated bearing body 1, the number of the circulating oil storage grooves 2 is equal to the number of the outer diameter exhaust grooves 5 and the plane exhaust grooves 6 and the three correspond one by one. On one side plane of the oil-impregnated bearing body 1, the outer diameter exhaust groove 5 is communicated with the circulating oil storage groove 2. The outer diameter exhaust groove 5 and the plane exhaust groove 6 can play a role in heat dissipation. The inner diameter circulating oil-impregnated bearing with or without an exhaust groove can be selected according to the applicable type and economic conditions of the fan product, greatly improving the applicable range of the inner diameter circulating oil-impregnated bearing.
[0030] Even further, as Figure 1 、 Figure 2 and Figure 5 shown, the two side planes of the oil-impregnated bearing body 1 are divided into: having a plane depression 7 and not having a plane depression 7. The upper plane depression 7 of the oil-impregnated bearing body 1 with the plane depression 7 is communicated with the plane exhaust groove 6. The plane depression 7 corresponds to the mounting block on the blade shaft core, which is suitable for the installation of the inner diameter circulating oil-impregnated bearing on various fans, can reduce the installation difficulty of the inner diameter circulating oil-impregnated bearing, and improve the production speed of the fan.
[0031] Even more further, as Figure 2 and Figure 3As shown, a convex ring 8 is fixedly arranged inside the planar recess 7. A plurality of uniformly distributed convex points 9 are fixedly arranged outside the convex ring 8 of the planar recess 7. Both the convex ring 8 and the convex points 9 are arranged outside the circulating oil storage groove 2. On the one hand, the convex ring 8 can slow down the liquid flow rate during rotation and can also prevent oil leakage during the use of the inner diameter circulating oil storage oil-impregnated bearing, thereby making the oil-impregnated bearing more durable in use and not requiring frequent refueling. The convex points 9 can reduce the friction between the planar recess 7 of the oil-impregnated bearing and the bearing connecting piece, prevent local overheating, and slow down the volatilization rate of the lubricating oil inside the oil-impregnated bearing. A plurality of uniformly distributed arc-shaped ribs 10 are fixedly arranged inside the planar exhaust groove 6. The arc-shaped ribs 10 can slow down the flow rate of the lubricating oil in the planar exhaust groove 6, thereby effectively improving the retention of the lubricating oil.
[0032] As Figures 1 - 5 shown, the principle of the inner diameter circulating oil storage oil-impregnated bearing provided in this embodiment is as follows:
[0033] A plurality of uniformly distributed circulating oil storage grooves 2 are provided at the inner diameter of the oil-impregnated bearing body 1. The circulating oil storage grooves 2 at the inner diameter of the oil-impregnated bearing body 1 can increase the oil storage capacity of the oil-impregnated bearing body 1. An oil groove gap 3 is provided between the circulating oil storage groove 2 and the inner wall of the oil-impregnated bearing body 1. The circulating oil storage groove 2 is communicated with the inside of the oil-impregnated bearing body 1 through the oil groove gap 3. Inner walls and oil storage groove interfaces 4 are fixedly arranged on both sides of the oil groove gap 3. The inner walls and oil storage groove interfaces 4 are of an arc-shaped structure, which is convenient for the lubricating oil to flow out from the circulating oil storage groove 2 onto the fan shaft core, making the fan rotate more smoothly. When the fan rotates at a high speed, the blade shaft core drives the oil in the inner diameter circulating oil groove 2 to continuously circulate and lubricate the blade shaft core, ensuring that the inner diameter wall of the inner diameter circulating oil storage bearing and the outer diameter of the product blade shaft core rotate at a high speed, reducing the friction coefficient and maintaining continuous circulating lubrication. The oil groove gap 3 can reduce the contact surface between the bearing inner wall and the blade shaft core, reduce its friction coefficient and heat generation, and thus effectively reduce the friction noise and abnormal noise generated during the use of the product, thereby greatly extending the service life of the oil-impregnated bearing.
