Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to intermediate bearings for ships with good cooling effect. Background Technology

[0002] Intermediate bearings, also known as tunnel bearings, are a type of bearing used in mechanical engineering to support the rotational motion of intermediate shafts. They are mainly used in ship shafting and transmission systems. These bearings are divided into two types: sliding and rolling. The sliding type is commonly used in the shipbuilding field. The body is made of steel or cast iron and the base is fixed by through bolts [7]. Common classifications include three-link type (SL type) and three-channel steel three-bearing type (SC type). Intermediate bearings for ships are key support components in ship shafting systems. They are mainly used to bear the radial load of intermediate shafts and compensate for installation errors.

[0003] Chinese Patent Publication No. CN211145137U discloses an intermediate bearing for a ship shaft, comprising a base, a reinforcing mechanism, a main body mechanism, an oil injection mechanism, a housing, an oil injection nozzle, a brush, a filter screen, a connecting pipe, and a cleaning mechanism. The beneficial effects of this utility model are: the brush is fixed to the side wall of the oil injection nozzle, facilitating the removal of dirt from the side wall of the oil injection pipe when the oil injection pipe is inserted into the nozzle, preventing dirt from entering the housing; when lubricating oil is poured into the housing, impurities in the lubricating oil accumulate at the bottom of the housing due to gravity, and the filter screen blocks these impurities; when the lubricating oil level is higher than the connecting pipe, the lubricating oil is poured into the bearing through the top of the connecting pipe, thus preventing impurities in the lubricating oil from entering the bearing's interior through the filter screen, reducing internal friction and promoting better bearing performance.

[0004] However, the aforementioned intermediate bearing generates high heat during actual long-term operation. Since it lacks a cooling structure, the intermediate bearing wears faster due to high temperature, affecting its service life and thus reducing its performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a marine intermediate bearing with improved cooling performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a marine intermediate bearing with good cooling effect, comprising an intermediate bearing body, wherein heat dissipation fins are provided on all four outer walls of the intermediate bearing body, two oil injection joints are provided on the top of the intermediate bearing body, a base is fixedly connected to the bottom of the intermediate bearing body, an assembly opening is provided on both sides of the outer outer wall of the base, a cooling device is provided inside the assembly opening, multiple heat dissipation vents are provided through the front and rear sides of the base, a fixed rotating shaft is rotatably connected to both sides of the inner wall of the base, a fixed cross plate is fixedly connected between one end of two fixed rotating shafts, the other end of one of the fixed rotating shafts passes through the base and is fixedly connected to a first synchronous pulley, and an installation component is connected to the side wall of the base;

[0007] The surface of the fixed horizontal plate is provided with a fixing groove, and two symmetrical moving components are movably sleeved on the outer side wall of the fixed horizontal plate.

[0008] As a further description of the above technical solution: the mounting assembly includes a mounting housing fixedly connected to the side wall of the base, and an L-shaped mounting plate is fixedly connected to the side wall of the base. The mounting housing serves to protect the motor mounted on the L-shaped mounting plate.

[0009] As a further description of the above technical solution: a mounting motor is fixedly connected to the side wall of the mounting L-shaped plate, and a mounting rod is fixedly connected to the output end of the mounting motor. The mounting motor is used to drive the mounting rod to rotate.

[0010] As a further description of the above technical solution: the end of the mounting rod is connected to an L-shaped plate and a second synchronous pulley is fixedly connected thereto. The second synchronous pulley is driven by a synchronous toothed belt meshing with the first synchronous pulley. The mounting rod drives the second synchronous pulley to rotate, and then the synchronous toothed belt drives the first synchronous pulley to rotate.

[0011] As a further description of the above technical solution: the movable component includes a movable sleeve block that is movably sleeved on the outer wall of the fixed horizontal plate. A drive motor is fixedly connected to the top of the movable sleeve block, and a drive rod is fixedly connected to the output end of the drive motor. The drive motor is used to drive the drive rod to rotate.

[0012] As a further description of the above technical solution: a drive fan blade is fixedly connected to the end of the drive rod, a moving motor is fixedly connected to the surface of the moving sleeve, and the output end of the moving motor is fixedly connected to the moving rod, so as to achieve the purpose of driving the moving rod to rotate.

[0013] As a further description of the above technical solution: the end of the moving rod passes through the moving sleeve and extends into the fixed groove. A moving wheel is fixedly connected to the end of the moving rod, so that the moving rod drives the moving wheel to rotate and move inside the fixed groove.

[0014] This utility model has the following beneficial effects:

[0015] The movable component allows the movable motor to drive the movable wheels to rotate. As the movable wheels contact the inner wall of the fixed groove and generate friction, the two movable wheels move closer or further apart within the groove. The movable motor then drives the movable sleeve block to move along the direction of the fixed horizontal plate, allowing the drive motor and drive fan blades on the movable sleeve block to adjust the airflow and evenly contact the cooling pipes on the cooling device, thus uniformly cooling the intermediate bearing body. The mounting component allows the mounting motor to drive the mounting rod and the second synchronous pulley to rotate. The second synchronous pulley then drives the first synchronous pulley to rotate via a synchronous toothed belt. The first synchronous pulley then drives the fixed horizontal plate on the fixed shaft to rotate in both directions. The movable component on the fixed horizontal plate also drives the drive fan blades to further evenly blow air into the cooling pipes of the cooling device, ensuring sufficient cooling of the intermediate bearing body. This cooling structure extends the service life of the intermediate bearing and improves its performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 The present invention provides a marine intermediate bearing with good cooling effect, comprising an intermediate bearing body 1, wherein heat dissipation fins 2 are provided on all four outer walls of the intermediate bearing body 1, two oil injection joints 3 are provided on the top of the intermediate bearing body 1, a base 4 is fixedly connected to the bottom of the intermediate bearing body 1, and assembly openings are provided on both sides of the outer outer wall of the base 4, with cooling devices 6 installed inside the assembly openings. Multiple heat dissipation vents 5 are provided through the front and rear sides of the base 4, and fixed rotating shafts 7 are rotatably connected to both sides of the inner wall of the base 4. A fixed cross plate 8 is fixedly connected between one end of two fixed rotating shafts 7, and the other end of one fixed rotating shaft 7 passes through the base 4 and is fixedly connected to a first cross plate. The step wheel 9 and the base 4 have a mounting assembly connected to their side walls. The mounting assembly is used to adjust the rotation of the first synchronous wheel 9. The mounting assembly includes a mounting housing 10 fixedly connected to the side wall of the base 4, a mounting L-shaped plate 11 fixedly connected to the side wall of the base 4, a mounting motor 12 fixedly connected to the side wall of the mounting L-shaped plate 11, a mounting rod 13 fixedly connected to the output end of the mounting motor 12, and a second synchronous wheel 14 fixedly connected to the end of the mounting rod 13 through the mounting L-shaped plate 11. The second synchronous wheel 14 meshes with the first synchronous wheel 9 through a synchronous toothed belt 15. The mounting motor 12 is used to drive the mounting rod 13 to rotate.

[0024] A fixing groove is provided on the surface of the fixed horizontal plate 8. Two symmetrical moving components are movably sleeved on the outer wall of the fixed horizontal plate 8. The moving components include a moving sleeve block 16 movably sleeved on the outer wall of the fixed horizontal plate 8. A drive motor 17 is fixedly connected to the top of the moving sleeve block 16. A drive rod is fixedly connected to the output end of the drive motor 17. A drive fan blade 18 is fixedly connected to the end of the drive rod. A moving motor 19 is fixedly connected to the surface of the moving sleeve block 16. A moving rod is fixedly connected to the output end of the moving motor 19. The end of the moving rod passes through the moving sleeve block 16 and extends into the fixing groove. A moving wheel 20 is fixedly connected to the end of the moving rod. The moving components achieve the purpose of adjusting the air blowing and heat dissipation.

[0025] Working principle: When in use, lubricating oil is first added to the inside of the intermediate bearing body 1 through the oil filling joint 3 as needed. Then, the external cap is sealed to the oil filling joint 3 by threads. Then, the heat dissipation fins 2 are used to initially dissipate heat from the intermediate bearing body 1 during operation.

[0026] Next, start the cooling device 6 on the base 4, and then start the drive motor 17. The drive motor 17 drives the drive fan blade 18 on the drive rod to rotate and blow air. Then the rotating air blown out passes through the cooling pipe on the cooling device 6 for conduction and condensation. Then the cold air passes through the base 4 to blow air and dissipate heat to the intermediate bearing body 1.

[0027] Then, the two moving motors 19 are started, which drive the moving rod and the moving wheel 20 to rotate. Because the moving wheel 20 contacts the inner wall of the fixed groove and generates friction, the two moving wheels 20 move closer or further away from each other inside the fixed groove. Then, the moving motor 19 also drives the moving sleeve block 16 to move along the direction on the fixed horizontal plate 8, so that the drive motor 17 and drive fan blade 18 on the moving sleeve block 16 adjust the air blowing, so that the air comes into contact with the cooling pipe on the cooling device 6 evenly, thereby blowing air evenly to cool and dissipate heat on the intermediate bearing body 1 on the base 4.

[0028] Simultaneously, the mounting motor 12 is started, which drives the mounting rod 13 and the second synchronous pulley 14 to rotate. Then, the second synchronous pulley 14 drives the first synchronous pulley 9 to rotate through the synchronous toothed belt 15.

[0029] As the first synchronous wheel 9 drives the fixed horizontal plate 8 on the fixed shaft 7 to rotate in both directions, the moving component on the fixed horizontal plate 8 also drives the drive fan blade 18 and the cooling pipe on the cooling device 6 to blow air evenly, so that the cold air can fully blow air to the intermediate bearing body 1 to dissipate heat. Then the excess heat dissipation air is directly discharged through multiple heat dissipation ports 5.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
