Description

Technical Field

[0001] The present invention relates to the technical field of bearing housing lubrication, and particularly to a long-term self-lubricating device for a fan bearing housing. Background Art

[0002] Fan bearing housing lubrication refers to the process of using lubricating oil inside the fan bearing housing to reduce the friction between the bearing and the shaft, reduce wear, and thus ensure the smooth operation of the fan and extend the service life of the equipment. Good lubrication can also effectively dissipate heat, prevent equipment damage caused by high temperature, and keep the fan running efficiently. Regular maintenance and replacement of lubricating oil are key links to ensure the normal operation of the fan bearing housing.

[0003] When lubricating the fan bearing housing, regularly replenishing the lubricating oil can ensure the normal operation of the bearing. However, the lubricating oil is prone to chemical reactions with oxygen under high temperature, high pressure, or long-term operation, producing oxidation products and gradually forming a black gel-like substance. This substance will change the viscosity and fluidity of the lubricating oil, making it unable to evenly cover the bearing surface, increasing friction and wear, and seriously affecting the lubrication effect and bearing life. Once the black gel substance is generated, in order to restore the lubrication state of the bearing housing and extend the equipment life, it is necessary to disassemble the machine for in-depth cleaning.

[0004] Based on the above situation, the present invention proposes a long-term self-lubricating device for a fan bearing housing. Summary of the Invention

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation manners and with reference to the attached drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0031] Embodiment 1: A long-term self-lubricating device for a fan bearing seat, as Figures 1-6 shown, includes a base 1. A shaft rod 101 is placed on the upper part of the base 1. A sealing cover 2 is fixedly connected to the top of the base 1 by bolts. A bearing 3 symmetrically arranged along the left and right of the base 1 is fixedly installed between the base 1 and the sealing cover 2. Two sealing rings 301 are sleeved on the outer diameter side wall of the bearing 3. A liquid storage tank 5 is fixedly connected to the middle of the top of the sealing cover 2. A feeding rack 6 symmetrically arranged along the left and right of the base 1 is fixedly connected between the base 1 and the sealing cover 2. The feeding rack 6 is communicated with the liquid storage tank 5. Liquid outlet ports are evenly arranged circumferentially on the inner side adjacent to the bearing 3 of the feeding rack 6. A circulation rack 7 is fixedly connected to the lower part of the bearing 3. A first turbine 8 is fixedly installed in the circulation rack 7. A fastening cover 4 is fixedly connected to the outermost end face of the base 1 and the sealing cover 2.

[0032] A sufficient amount of lubricating oil is previously stored at the bottom of the liquid storage tank 5. In order to achieve the long-term self-lubrication of the bearing 3, the first turbine 8 is started. Under the driving force of the first turbine 8, the lubricating oil first flows to the bearing 3 through the feeding rack 6. After passing through the bearing 3, the lubricating oil then flows into the circulation rack 7 and then flows to the inner top of the liquid storage tank 5. In this way, the present invention forms a circulating oil circuit system through these lines of the liquid storage tank 5, the feeding rack 6 and the circulation rack 7. The first turbine 8 drives the lubricating oil to circulate in this oil circuit system, so as to achieve the long-term self-lubrication effect on the bearing 3, and at the same time, the effect of cooling the lubricating oil can also be achieved during the circulation.

[0033] As Figure 3 、 Figure 5 and Figure 6As shown in the figure, it further includes a filter plate 9. The filter plate 9 is vertically slidably connected inside the circulation frame 7. Springs 10 are fixedly connected between the filter plate 9 and the circulation frame 7 and are symmetrically arranged before and after the filter plate 9. An inductor 11 is fixedly installed inside the circulation frame 7. A contact rod 12 is horizontally and fixedly connected to the side of the filter plate 9 adjacent to the inductor 11. The contact rod 12 is in contact and cooperation with the inductor. A second turbine 13 is fixedly installed at the bottom of the circulation frame 7. The second turbine 13 is electrically connected to the inductor 11 through a control module. A discharge pipe 14 is fixedly connected to the inner side of the circulation frame 7. One side of the top of the discharge pipe 14 is fixedly connected to the upper front side of the liquid storage tank 5. A baffle 16 is slidably connected to the side of the circulation frame 7 adjacent to the discharge pipe 14. The baffle 16 is used to partition the circulation frame 7. A filter box 15 is clamped at the upper front side inside the liquid storage tank 5. The filter box 15 is located directly below the discharge pipe 14.

[0034] To prevent the filter plate 9 from getting blocked and affecting the circulation of the lubricating oil, when the filter plate 9 gets blocked, the flow of the lubricating oil is obstructed, thereby pushing the filter plate 9 and the contact rod 12 to move to the left. The spring 10 is deformed and compressed under the force. When the contact rod 12 moves to contact the inductor 11, the inductor 11 emits an electrical signal. After the control module receives the electrical signal, it controls the first turbine 8 to stop rotating and the second turbine 13 to start. The second turbine 13 pumps the lubricating oil into the discharge pipe 14. Subsequently, the lubricating oil passes through the discharge pipe 14 and pours into the filter box 15 to filter and collect the impurities in the lubricating oil. The filtered impurities finally flow back into the liquid storage tank 5. In this way, through the cooperation of the filter plate 9 and the second turbine 13, the present invention realizes automatically switching the circulation path when the filter plate 9 gets blocked, ensuring the cyclic supply of the lubricating oil.

[0035] Moreover, through the filter box 15, the present invention automatically and timely filters and cleans the black gel substances in the lubricating oil and collects them, avoiding the influence on the viscosity and fluidity of the lubricating oil, improving the lubrication effect of the bearing 3 and extending its service life. And only the filter box 15 needs to be disassembled for cleaning, without the need to disassemble the machine for in-depth cleaning.

[0036] Embodiment 2: On the basis of Embodiment 1, as Figure 7 and Figure 8 shown, it further includes a baffle 16. The baffle 16 is slidably connected to the lower side of the circulation frame 7. A clamping plate 17 is fixedly connected to the side of the filter plate 9 away from the baffle 16. An isolation plate is provided in the middle of the clamping plate 17 for changing the flow path of the lubricating oil. Slide plates 18 are slidably connected to the circulation frame 7 and are symmetrically arranged before and after the circulation frame 7. A rotating guide plate 19 is connected between the symmetrically arranged slide plates 18. The rotating guide plate 19 cooperates with the clamping plate. A torsion spring 20 is fixedly connected between the slide plate 18 and the rotating guide plate 19. A limiting block 191 is fixedly connected to the middle of the side of the circulation frame 7 adjacent to the clamping plate 17. A fixing rod 21 is fixedly connected to one side of the inner top of the circulation frame 7. The fixing rod 21 is in contact and cooperation with the rotating guide plate 19 for limiting the rotating guide plate 19.

[0037] When the filter plate 9 slides to the left, the filter plate 9 drives the card plate 17 to move to the left, so that the card plate 17 no longer blocks the slide plate 18. Under the action of gravity, the slide plate 18 slides downward along the slide groove of the circulation frame 7 and drives the rotating guide plate 19 to move downward. As the rotating guide plate 19 moves downward and disengages from the fixed rod 21, the right side of the rotating guide plate 19 swings to the bottom and contacts the limit block 191 under the reset action of the torsion spring 20, and the left side of the rotating guide plate 19 contacts the isolation plate on the card plate 17. At this time, the rotating guide plate 19 tilts to the lower right to form two upper and lower chambers. The lubricating oil entering the circulation frame 7 begins to flow along the upper chamber formed by the rotating guide plate 19 and the isolation plate, and finally flows from the right side of the filter plate 9. To the left side of the filter plate 9. At the same time, when the filter plate 9 moves to the left, the control module is driven to start the second turbine 13 by triggering the sensor 11. The lubricating oil driven by the second turbine 13 lifts the baffle 16 upward to block the circulation frame 7 to form a flow channel. Subsequently, the lubricating oil on the left side of the filter plate 9 is blocked by the baffle 16 and cannot flow to the left side. Finally, the lubricating oil on the left side of the filter plate 9 is guided by the second turbine 13 and flows from the lower left part of the filter plate 9 to the lower chamber on the right side of the filter plate 9. During this period, the impurities on the filter plate 9 are backwashed. In this way, the lubricating oil can better backwash the black gel substance on the filter plate 9 and improve the cleaning effect.

[0038] When the filter plate 9 slides to the right, the filter plate 9 drives the card plate 17 to move to the right, and the card plate 17 contacts the slide plate 18. Under the extrusion of the inclined surface of the card plate 17, the slide plate 18 slides upward along the slide groove of the circulation frame 7 and drives the rotating guide plate 19 to move upward. As the rotating guide plate 19 moves upward and contacts the fixed rod 21, the rotating guide plate 19 swings in the opposite direction and resets under the extrusion of the fixed rod 21, and the torsion spring 20 deforms, thereby realizing automatic reset.

[0039] Embodiment 3: Based on embodiment 2, Figure 9 As shown, a rotating rack 22 is also included, which is connected to the feed rack 6. The outer wall of the rotating rack 22 is evenly provided with push plates in the circumferential direction. The push plates are in contact with the side walls of the grooves of the feed rack 6 to drive the lubricating oil in the rotating rack 22 and prevent the lubricating oil from being deposited at the bottom of the rotating rack 22.

[0040] When the lubricating oil in the liquid storage tank 5 needs to enter the bearing 3 for lubrication, first, the negative pressure generated during the operation of the first turbine 8 sucks the lubricating oil in the bearing 3 seat into the circulation frame 7. Subsequently, the negative pressure generated inside the bearing 3 seat evenly sucks the lubricating oil in the feeding frame 6 into the uniform feeding frame 6, thereby driving the liquid in the liquid storage tank 5 into the feeding frame 6. When the lubricating oil enters the feeding frame 6, the flowing lubricating oil drives the rotating frame 22 to rotate, thus causing the lubricating oil in the feeding frame 6 to flow better, preventing the lubricating oil from depositing at the bottom of the feeding frame 6 for a long time to generate gel substances and affecting the quality of the lubricating oil. In this way, through the cooperation of the feeding frame 6 and the first turbine 8, the lubricating oil evenly enters the bearing 3 seat. At the same time, through the cooperation of the feeding frame 6 and the rotating frame 22, it is realized to promote the flow of the lubricating oil deposited at the bottom of the feeding frame 6 and prevent the lubricating oil at the bottom of the feeding frame 6 from depositing for a long time to generate gel and affect the lubrication quality of the lubricating oil.

[0041] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present invention.
