Description

Technical Field

[0001] This invention relates to the field of marine bearing locking and clamping technology, specifically a marine bearing locking and clamping mechanism with a self-cleaning function. Background Technology

[0002] Marine bearings are core components of ship propulsion systems, steering gears, and other critical transmission parts. Their reliability and lifespan directly affect the ship's operational safety and maintenance costs. Because ships operate in harsh marine environments with high humidity and salt spray, bearings not only have to withstand enormous mechanical loads but are also highly susceptible to contaminants such as seawater, salt, and dust, leading to lubrication failure, accelerated wear, and even jamming or premature damage.

[0003] Traditional marine bearing locking and clamping mechanisms primarily focus on mechanical locking and load-bearing. For bearing sealing and protection, they often employ passive protection methods such as contact seals or labyrinth seals. These methods are prone to failure after long-term operation due to seal wear and aging, making them ineffective at preventing external contaminants. Simultaneously, impurities easily mix into the lubricating fluid during circulation, accelerating bearing wear, and the detached wear particles further contaminate the lubricating fluid, creating a vicious cycle.

[0004] To address the aforementioned issues, an improved marine bearing locking and clamping mechanism with a self-cleaning function is now designed. Summary of the Invention

The end of the liquid inlet pipe 19 away from the bearing housing 1 passes through the mounting base 20 and is fixedly connected to a second infusion pump 18. The input end of the second infusion pump 18 is located at the bottom of the liquid storage tank 16, and the input end of the second infusion pump 18 is connected to the output end of the liquid outlet pipe 3. A filter screen 24 for filtering lubricating fluid is horizontally fixedly connected to the inner wall of the storage tank 16. A filling port 15 is fixedly connected to the upper end of the side wall of the storage tank 16. A second transparent observation port 17 is vertically opened on the side wall of the storage tank 16 to facilitate observation of the lubricating fluid inside the storage tank 16.

A cleaning mechanism for cleaning the filter screen 24 is provided at the upper end of the filter screen 24. Protective mechanisms for preventing external air from entering the bearing seat 1 are provided at both ends of the bearing seat 1.

[0027] The protective mechanism includes an air purifier 21. Both ends of the bearing seat 1 are fixedly connected to a fixed frame 2. A through hole 28 is provided at the center of the fixed frame 2 to facilitate the passage of the rotating shaft. The diameter of the through hole 28 is larger than the diameter of the rotating shaft. An air supply pipe 23 is fixedly connected to the side wall of the fixed frame 2. The end of the air supply pipe 23 away from the fixed frame 2 is fixedly connected to the output end of the air purifier 21. An air pump 22 is installed on the side wall of the air supply pipe 23 to transport the air purified by the air purifier 21 to the inside of the fixed frame 2.

[0028] When in use, start the air pump 22. The air pump 22 delivers the air purified by the air purifier 21 to the inside of the fixed frame 2 through the air pipe 23. Then, the air is discharged outward through the perforation 28, thereby preventing external air dust from entering the bearing seat 1 and protecting the bearing seat 1.

[0029] The cleaning mechanism includes a fixed cylinder 4, which is vertically fixed to the center of the top of the storage tank 16. A rotating tube 7 is rotatably connected to the inner wall of the fixed cylinder 4. The lower end of the rotating tube 7 is in close contact with the upper end of the filter screen 24. A collection frame 25 for cleaning the upper end of the filter screen 24 is horizontally fixed to the lower end of the side wall of the rotating tube 7. A rotary joint 6 is fixedly connected to the upper end of the rotating tube 7 through the fixed cylinder 4. A first gear 5 is fixedly connected to the side wall of the rotating tube 7 above the storage tank 16. A motor 10 is fixedly connected to the upper end of the storage tank 16. A second gear 8 is fixedly connected to the output end of the motor 10. The second gear 8 meshes with the first gear 5. Suction components for extracting impurities from the upper end of the filter screen 24 from the storage tank 16 are provided on the collection frame 25 and the side wall of the storage tank 16.

[0030] When in use, start the motor 10. The output end of the motor 10 drives the second gear 8 to rotate. The second gear 8 drives the first gear 5 to rotate. The first gear 5 drives the rotating tube 7 to rotate. The rotating tube 7 drives the collection frame 25 to rotate, so that the collection frame 25 cleans the upper end of the filter screen 24.

[0031] The suction assembly includes a first infusion pump 12. A plurality of openings 26 are provided on one side wall of the collection frame 25. The openings 26 face the rotation direction of the collection frame 25. A guide block 27 is fixedly connected to the side wall of the collection frame 25 between two adjacent openings 26 to facilitate the entry of impurities into the opening 26. The first infusion pump 12 is fixedly connected to the side wall of the storage tank 16. A drain pipe 13 is fixedly connected to the output end of the first infusion pump 12. A connecting pipe 9 is fixedly connected to the input end of the first infusion pump 12. The end of the connecting pipe 9 away from the first infusion pump 12 is fixedly connected to the end of the rotary joint 6 away from the rotating pipe 7. An electrically controlled valve 11 for controlling the opening and closing of the connecting pipe 9 is installed on the side wall of the connecting pipe 9.

[0032] When the collection frame 25 rotates, the first infusion pump 12 is started. Under pressure, the impurities at the top of the filter screen 24 are sucked into the collection frame 25 through the opening 26, and then pass through the rotating pipe 7, the rotary joint 6, the connecting pipe 9, the electric control valve 11, the first infusion pump 12, and the drain pipe 13 in sequence, and are finally discharged through the drain pipe 13.

[0033] Working principle of a marine bearing locking and clamping mechanism with self-cleaning function: When in use, start the air pump 22. The air pump 22 delivers the air purified by the air purifier 21 to the inside of the fixed frame 2 through the air pipe 23. Then, the air is discharged outward through the perforation 28, forming a positive pressure airflow barrier, which effectively prevents external dust, moisture and other pollutants from entering the bearing housing, ensuring the long-term stable operation of the bearing in the harsh marine environment.

[0034] During use, the lubricant is stored in the storage tank 16 and pumped into the bearing housing 1 through the inlet pipe 19 by the second pump 18 to lubricate the bearing. After use, the lubricant flows back to the upper part of the storage tank 16 through the outlet pipe 3. When it flows through the filter screen 24, impurities are trapped above the filter screen, thus achieving preliminary purification of the lubricant.

[0035] Start the motor 10. The output end of the motor 10 drives the second gear 8 to rotate. The second gear 8 drives the first gear 5 to rotate. The first gear 5 drives the rotating tube 7 to rotate. The rotating tube 7 drives the collection frame 25 to rotate, so that the collection frame 25 cleans the upper end of the filter screen 24.

[0036] When the collection frame 25 rotates, the first infusion pump 12 is started. Under pressure, the impurities at the top of the filter screen 24 are sucked into the collection frame 25 through the opening 26, and then pass through the rotating pipe 7, the rotary joint 6, the connecting pipe 9, the electric control valve 11, the first infusion pump 12, and the drain pipe 13 in sequence, and finally discharged through the drain pipe 13, realizing the automatic cleaning of the filter screen 24 and the collection of impurities.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
