The lubrication of the bearings during fan operation is crucial to the life and stable operation of the fan.

[0003] An axial cooling fan is disclosed in Chinese patent application No. 202322388346.0, including a main frame, a stator, a circuit board, a fan blade and a rotor.

[0052] During use, the bearing becomes hot, and the oil in the oil storage area 13 of the bearing expands and flows out through the oil groove 81, the upper oil channel 82, and the lower oil channel 83 to participate in lubrication.

[0068] The setting of the washer 9 prevents the buckle ring 10 from rubbing against the inner wall of the oil-containing bearing 8, thereby avoiding damage to the oil-containing bearing 8;

[0069] The setting of the buckle ring 10 effectively fixes the shaft core 2 to prevent the fan blade 1 from falling off.

[0070] Example 3

[0071] See also Figure 6-7 On the basis of Embodiment 1-2, a rotation stabilization component is provided between the shaft core 2 and the fan blade 1, and the rotation stabilization component includes a stabilization plate 14, and the stabilization plate 14 is connected to the middle tube of the bracket, and the shaft core 2 passes through the stabilization plate 14 and is connected to a power pulley, and a middle transmission wheel 16 is slidably connected to the stabilization plate 14, and the middle transmission wheel 16 can rotate around the axis, and the power pulley and the middle transmission wheel 16 rotate through a transmission belt 17;

[0072] The stabilizing plate 14 is connected to a gear ring 15, and a plurality of stabilizing gears 19 are arranged in the gear ring 15, and the stabilizing gears 19 are all meshed with the gear ring 15, and the stabilizing gears 19 are fixedly connected to a linkage rod 20, and the lower end of the linkage rod 20 is rotatably connected to the stabilizing plate 14, and the upper end of the linkage rod 20 passes through a top plate 25 arranged above the stabilizing plate 14 and is connected to a swivel, and the upper end of the linkage rod 20 is fixedly connected to a buffer gear, and the buffer gear is meshed with the swivel, and the swivel is rotatably connected to the fan blade 1;

[0073] A power gear 27 is disposed inside the gear ring 15 , and the power gear 27 is meshed with the gear ring 15 . The power gear 27 is fixedly connected to the side wheels 18 via a synchronization shaft 26 , and the synchronization shaft 26 is rotationally connected to the stabilizing plate 14 .

A side limiting wheel 23 is rotatably connected to the fixed snap ring 22, and the side limiting wheel 23 abuts against the outer side wall of the gear ring 15.

[0075] A narrowed limiting ring is provided at the lower side of the gear ring 15, and the limiting ring is connected to a limiting slot 24 provided on the stabilizing plate 14;

[0076] The stabilizing plate 14 is connected to the top plate 25 via fixing bolts 21 .

[0077] The working principle and beneficial effects of the above scheme:

[0078] When the fan blade 1 is driven to rotate, the shaft core 2 drives the power pulley to rotate, and transmits the power to the side wheel 18 through the middle transmission wheel 16 and the transmission belt 17, thereby driving the power gear 27 to rotate. When the power gear 27 rotates, the gear ring 15 is driven to rotate. Since the gear ring 15 is meshed with the stabilizing gear 19, the stabilizing gear 19 rotates around the linkage rod 20. The linkage rod 20 is connected to the swivel, driving the swivel to rotate relative to the fan blade 1. The shaft core 2 is connected to the fan blade 1, so that the fan blade 1 rotates under the drive of the shaft core 2 and also rotates relative to the swivel. At the same time, the linkage rod 20 arranged on the outer periphery of the shaft core 2 supports the fan blade 1, ensuring the stability of the rotation of the fan blade 1.

[0079] When the fan blade 1 rotates, the fan blade 1 rotates relative to the rotating ring, and the rotating ring rotates relative to the gear ring 15. In this process, the stabilizing gear 19, the linkage rod 20, and the rotating ring that provide support for the fan blade 1 all rotate, but the rotation of the stabilizing gear 19, the linkage rod 20, the rotating ring and other parts is slowed down relative to the fan blade 1, that is, the wear of the parts that provide the stabilizing function to the fan blade 1 is effectively reduced, which is conducive to long-term use and enhances the practicality of the structure;

[0080] Since the rotation of the fan blades 1 is not a constant and stable process, vibrations will be generated, which will exert a certain radial force on the shaft core 2, causing wear of the shaft core 2. While the rotation stabilization component provides stable rotation for the fan blades 1, it also reduces the radial force of the fan blades 1 on the shaft core 2, thereby avoiding wear of the shaft core 2.

[0081] Example 4

[0082] See also Figure 8-9On the basis of Embodiments 1-3, an adjustment component is provided between the shaft core 2 and the fan blade 1, and the adjustment component includes a fixing plate 28, the fixing plate 28 is fixedly connected to the lower surface of the fan blade 1, the lower surface of the fixing plate 28 is fixedly connected to the shaft core 2, and an adjustment rod 29 is provided on the lower surface of the fixing plate 28, the lower end surface of the adjustment rod 29 is an inclined surface, the adjustment rod 29 abuts against an adjustment block 30 slidably connected to the mounting plate 31, the longitudinal section of the adjustment block 30 is a trapezoid, and the mounting plate 31 is fixedly connected to the middle tube of the bracket;

[0083] A slider 32 is fixedly connected to the lower surface of the adjustment block 30. The slider 32 passes through the mounting plate 31 and is slidably connected to the mounting plate 31. An adjustment ring 33 is fixedly connected to one end of the slider 32 located below the mounting plate 31, and one end of the adjustment ring 33 is sleeved on the outer side of the shaft core 2.

[0084] The working principle and beneficial effects of the above scheme:

[0085] The rotation stabilization component can ensure a certain rotation stability of the fan blade 1, but cannot adjust the movement of the fan blade 1 when the fan blade 1 rotates in a biased direction;

[0086] When the rotation of the fan blade 1 shows a certain deflection, it will drive the fixing plate 28 to deflect, and the adjusting rod 29 connected to the lower surface of the fixing plate 28 on the lower side will squeeze the adjusting block 30, driving the adjusting block 30 to have a displacement tendency, thereby driving the adjusting ring 33 to apply a force to the shaft core 2, and this force is opposite to the force of the deflection of the fan blade 1, and a torque is formed at the connection between the shaft core 2 and the mounting plate 31, which has a tendency to deflect the shaft core 2 in the opposite direction, so that the shaft core 2 returns to the normal position;

[0087] The adjustment component can automatically assist the fan blade 1 to return to the correct position when the fan blade 1 is deflected, thereby further enhancing the stability of the fan blade 1 and facilitating the long-term operation of the fan.

[0088] Example 5

[0089] An oil circuit circulation method for an oil-containing bearing fan is used to design an oil circuit for an oil-containing bearing fan, comprising:

[0090] S1: When the fan blade 1 starts to rotate, the shaft core 2 in the oil-containing bearing 8 starts to rotate, and the friction between the shaft core 2 and the inner hole 84 wall of the oil-containing bearing 8 causes the lubricating oil to overflow from the oil groove 81, the upper oil channel 82, and the lower oil channel 83, forming a thin oil film on the surface of the oil-containing bearing 8;

[0091] S2: The fan blade 1 generates heat during rotation, and the lubricating oil in the oil storage area 13 expands due to the heat, and overflows from the oil groove 81, the upper oil channel 82, and the lower oil channel 83 to the contact surface of the oil-containing bearing 8;

[0092] S3: When the fan blade 1 stops rotating, the lubricating oil will flow back into the oil storage area 13 through the oil groove 81, the upper oil channel 82 and the lower oil channel 83 due to the drop in temperature.

[0093] The working principle and beneficial effects of the above scheme:

[0094] That is, when the fan starts to rotate, the shaft core 2 in the oil-containing bearing 8 begins to rotate, and the friction between the shaft core 2 and the inner wall of the oil-containing bearing 8 causes the lubricating oil to overflow from the pores, forming a thin oil film on the surface of the oil-containing bearing 8. This oil film reduces friction and wear, thereby ensuring that the fan can run quietly and smoothly. The fan will generate heat during operation, and the lubricating oil in the bearing will expand due to the heat, causing more lubricating oil to be brought to the contact surface, thereby ensuring sufficient lubrication at the operating temperature. At the same time, when the fan stops running, the lubricating oil will be reabsorbed by the pores due to the drop in temperature, forming a natural circulating lubrication system.

[0095] When the fan starts to rotate, the lubricating oil rises along the shaft core 2 to the oil sealing cover 7, and no longer flows upward. After radially moving through the upper oil channel 82 above the oil-containing bearing 8, it flows downward from the oil groove 81 on the outer diameter surface of the oil-containing bearing 8 to the bottom, and returns to the oil storage area 13 through the lower oil channel 83, forming a set of oil circulation system, which greatly reduces the overflow and volatilization of the lubricating oil, and achieves the purpose of improving the current oil-containing fan to increase the oil storage capacity and improve the leakage of the lubricating oil, thereby improving the various performances of the fan and extending the life of the fan.
