Description

Technical Field

[0001] This utility model relates to the technical field of ultra-thin wall bearing devices, specifically a high-stability, corrosion-resistant single-point mooring ultra-thin wall bearing device. Background Technology

[0002] A single-point mooring system is a crucial piece of equipment used in offshore oil production systems to moor floating structures such as floating production storage and offloading (FPSO) vessels at a fixed point at sea, allowing the floating structures to rotate freely around that point under the influence of wind, waves, and currents. Among these components, the bearing assembly is a key element, and its performance directly affects the stability and reliability of the entire system.

[0003] A novel ultrathin-walled, highly wear-resistant ceramic bearing (CN201820680143.5) effectively reduces friction and significantly improves heat dissipation efficiency, exhibiting excellent practicality. It can operate stably even in environments with significant temperature variations, and possesses high hardness and wear resistance. However, it has shortcomings: its protective properties against existing equipment are inadequate, and its corrosion resistance, thermal conductivity, and overall performance are also poor. Therefore, a highly stable, corrosion-resistant, single-point mooring ultrathin-walled bearing device is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable, corrosion-resistant, single-point mooring ultra-thin-walled bearing device to solve the problems mentioned in the background art, such as poor protection, poor corrosion resistance, poor thermal conductivity, poor performance, and inconvenience in use of novel ultra-thin-walled, highly wear-resistant ceramic bearings.

A reinforcing support plate is fixedly connected to the outer wall of the bolt seats, and a second fixing bolt is inserted into the inner wall of the bolt seats and the heat-conducting blocks. An oil injection port is formed in the middle of the inner wall of the reinforcing support plate, and splicing slots are formed on the upper and lower edges of the inner side of the reinforcing support plate. An installation block is inserted into the inner wall of the splicing slot, and a ball bearing is slidably embedded on one side of the installation block. A first fixing bolt is inserted into the side of the installation block and the reinforcing support plate.

[0006] Preferably, the outer ring and inner ring are made of duplex stainless steel, the coating is distributed around the outer ring and inner ring in an enclosing position, and the coating is a double-layer structure of nano-ceramic coating and organic fluorocarbon coating.

[0007] Preferably, the ball bearing is made of zirconia ceramic, and the ball bearing is installed with limiting support to the outer ring body and the inner ring body through a groove retainer.

[0008] Preferably, the shape of one end of the bolt seat matches the shape of one end of the heat-conducting block, and the bolt seat, the heat-conducting block, and the second fixing bolt are all made of copper. The oil inlet has a funnel structure.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-6This utility model provides a technical solution: a high-stability, corrosion-resistant, single-point mooring ultra-thin-walled bearing device, comprising an outer ring body 1, an inner ring body 2, a cage 3, a heat-conducting block 4, balls 5, a groove 6, a bolt seat 7, an oil inlet 8, a reinforcing support plate 9, a coating 10, a splicing slot 11, a sliding ball 12, a mounting block 13, a first fixing bolt 14, and a second fixing bolt 15. The inner ring body 2 is installed on the inner wall of the outer ring body 1, and balls 5 are slidably installed between the outer ring body 1 and the inner ring body 2. The outer ring body 1 and the inner ring body 2 are made of duplex stainless steel. The coating 10 is distributed in a wrapping position with the outer ring body 1 and the inner ring body 2, and the coating 10 has a double-layer structure of nano-ceramic coating and organic fluorocarbon coating, thus making the outer ring body 1 and the inner ring body 2 more stable and corrosion-resistant. The outer ring 1 and inner ring 2 have a stable structure and are effectively corrosion-resistant through the coating 10. The ball bearing 5 is made of zirconia ceramic and is supported and installed with the outer ring 1 and inner ring 2 by the retainer 3 and the groove 6, which makes the ball bearing 5 slide stably, structurally stable, and performs better. The outer walls of the outer ring 1 and inner ring 2 are coated with the coating 10, and the inner walls of the outer ring 1 and the outer walls of the inner ring 2 are both provided with grooves 6. The ball bearing 5 is inserted and slidably installed in the grooves 6, and the retainer 3 is fitted on the outer wall of the ball bearing 5. Heat-conducting blocks 4 are embedded in the inner walls on both sides of the retainer 3, and bolt seats 7 are attached to one end of the heat-conducting blocks 4. The shape of one end of the bolt seat 7 matches the shape of one end of the heat-conducting block 4. Furthermore, the bolt seat 7, the heat-conducting block 4, and the second fixing bolt 15 are all made of copper. The oil inlet 8 has a funnel structure, which allows the ball bearing 5 to effectively dissipate heat through the bolt seat 7, the heat-conducting block 4, and the second fixing bolt 15, and also facilitates the addition of lubricating oil and prevents rapid leakage. A reinforcing support plate 9 is fitted and fixedly connected to the outer wall of the bolt seat 7, and the second fixing bolt 15 is inserted and installed on the inner wall of the bolt seat 7 and the heat-conducting block 4. The reinforcing support plate 9 is bolted and fixedly installed on the heat-conducting block 4 and the retainer 3 by the second fixing bolt 15. The reinforcing support plate 9 is also fitted and supported by the outer ring body 1 and the inner ring body 2. The outer ring body 1 and the inner ring body 2 are slidably connected to the reinforcing support plate 9 by the sliding ball 12. This design facilitates bolt fixing of the reinforcing support plate 9, allowing it to wrap and support the sides of the outer ring 1 and inner ring 2, providing excellent protection and stable rotation. An oil inlet 8 is located in the middle of the inner wall of the reinforcing support plate 9, and splicing slots 11 are provided on the upper and lower edges of the inner side of the reinforcing support plate 9. An installation block 13 is inserted into the inner wall of the splicing slot 11, and a sliding ball 12 is rolled and embedded on one side of the installation block 13. The sliding ball 12 and the installation block 13 are connected to the splicing slot 11 by a first fixing bolt 14 in a bolted connection. This allows for easy independent disassembly and replacement of the sliding ball 12 and the installation block 13. The first fixing bolt 14 is inserted into one side of the installation block 13 and the reinforcing support plate 9.

[0021] Working principle: When using this high-stability, corrosion-resistant, single-point mooring ultra-thin-walled bearing device, the device is first assembled and installed. Then, the reinforcing support plate 9 is positioned and fitted with the cage 3 through the bolt seat 7, and then bolted and fixed by the second fixing bolt 15, thereby covering the outer ring body 1 and the inner ring body 2. In use, the outer ring body 1, the inner ring body 2 and the reinforcing support plate 9 can be slid and moved by the sliding ball 12. The heat generated when the ball 5 slides with the groove 6 will be quickly conducted and dissipated through the heat conducting block 4, the bolt seat 7 and the second fixing bolt 15. When the lubricating oil needs to be adjusted, it can be injected through the funnel of the oil filling port 8. When the reinforcing support plate 9 and the sliding ball 12 are damaged, the bolts can be removed and the bearings can be quickly replaced. This is the usage process of this high-stability, corrosion-resistant, single-point mooring ultra-thin-walled bearing device.
