Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, specifically to a bearing bush. Background Technology

[0002] A bearing bush is a mechanical part used to support and reduce friction, typically installed in mechanical bearings and other rotating components. Its main function is to provide support and reduce friction between the shaft and the bearing, thereby ensuring stable shaft rotation and extending bearing life. Bearing bushes are usually made of metal or alloy materials, such as bronze and aluminum alloys, possessing good wear resistance and heat resistance. Working in conjunction with the bearing, the bearing bush bears the weight of the shaft and the forces generated during rotation, ensuring stable shaft operation and performance under certain loads. They evenly distribute and transmit loads, preventing deformation or damage to the shaft due to torsion or uneven stress.

[0003] However, most bearing bushes do not have a structure to detect the internal lubricating oil during use. As a result, technicians cannot observe the amount of lubricating oil stored inside the bush, which can lead to wear on the shaft and bearing bush when the lubricating oil dries out, causing damage to the shaft and bearing. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a bearing bush that solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution:

[0006] A bearing bush includes: a lower shell, an upper shell slidably connected to the upper surface of the lower shell, a cooling cavity formed in the inner wall of the upper shell, a cooling pipe fixedly connected to the inner wall of the upper shell, an oil pipe fixedly connected to the outer wall of the upper shell, a storage bottle slidably connected to the outer wall of the oil pipe, an installation ring fixedly connected to the outer walls of both the oil pipe and the storage bottle, a first fixing ring slidably connected to the outer wall of the installation ring, a second fixing ring rotatably connected to the outer wall of the first fixing ring, a locking rod rotatably connected to the outer wall of the second fixing ring, a fixing plate slidably connected to the inner wall of the locking rod, a spring fixedly connected to the outer wall of the fixing plate, a pressure rod slidably connected to the outer wall of the fixing plate, and the outer wall of the pressure rod slidably connected to the inner wall of the first fixing ring.

[0007] Furthermore, both the lower and upper shells have mounting grooves on their inner walls, and the inner wall of the lower shell is slidably connected to a bearing body.

[0026] Please see Figure 1-4 ,

[0027] A bearing bush includes: a lower shell 1, an upper shell 2 slidably connected to the upper surface of the lower shell 1, a cooling cavity 4 formed in the inner wall of the upper shell 2, a cooling pipe 3 fixedly connected to the inner wall of the upper shell 2, and the outer wall of the cooling pipe 3 fixedly connected to the inner wall of the cooling cavity 4, the cooling pipe 3 being arranged in two sets distributed on the inner walls of the lower shell 1 and the upper shell 2, and the cooling cavity 4 being arranged in a ring in the middle of the inner walls of the lower shell 1 and the upper shell 2, an oil pipe 5 fixedly connected to the outer wall of the upper shell 2, and four sets of oil pipe 5 distributed laterally on the left and right sides of the same surface of the lower shell 1 and the upper shell 2, a temporary storage bottle 7 slidably connected to the outer wall of the oil pipe 5, and an installation ring 6 fixedly connected to the outer walls of both the oil pipe 5 and the temporary storage bottle 7, the outer wall of the installation ring 6 being slidably connected to a first fixing ring 8, and the second fixing ring 8 being fixedly connected to the outer wall of the installation ring 6. A sealing groove is provided on the inner wall of a first fixing ring 8. The shape of the sealing groove is the same as that of the mounting ring 6. A second fixing ring 9 is rotatably connected to the outer wall of the first fixing ring 8. A locking rod 10 is rotatably connected to the outer wall of the second fixing ring 9. A fixing plate 11 is slidably connected to the inner wall of the locking rod 10. A locking groove is provided on the inner wall of the locking rod 10. The shape of the locking groove is the same as that of the fixing plate 11. Two sets of fixing plates 11 are slidably connected to the inner walls of the left and right sides of the first fixing ring 8. A pressure rod 13 is slidably connected to the outer walls of both fixing plates 11. The outer walls of the pressure rods 13 are slidably connected to the inner walls of the first fixing ring 8. A spring 12 is fixedly connected to the outer wall of the fixing plate 11. The other end of the spring 12 is fixedly connected to the inner wall of the first fixing ring 8.

[0028] Both the lower shell 1 and the upper shell 2 have mounting grooves 16 on their inner walls. The inner wall of the lower shell 1 is slidably connected to the bearing body 14, and the outer wall of the bearing body 14 is provided with an anti-slip block. The outer wall of the anti-slip block is slidably connected to the inner wall of the mounting groove 16. The bearing body 14 is slidably connected to the inner wall of the upper shell 2. The inner wall of the bearing body 14 has an oil groove 15. The inner wall of the bearing body 14 is rotatably connected to the shaft 17, and the outer wall of the shaft 17 is fixedly connected to a limit ring. The outer wall of the limit ring is rotatably connected to the inner wall of the oil groove 15. Multiple sets of oil grooves 15 are distributed on the left and right sides and the middle of the bearing body 14. The lower surface of the lower shell 1 is fixedly connected to a support base 18.

[0029] A fixing block 19 is slidably connected to the inner wall of the support base 18, and a groove is provided on the inner wall of the support base 18. The groove is arranged in multiple square arrays. The inner wall of the groove is the same shape as the fixing block 19. The fixing block 19 is arranged in multiple square arrays and slides inside the groove of the support base 18. A groove is provided on the rear outer wall of the fixing block 19. A tension plate 20 is slidably connected inside the groove. The tension plate 20 is L-shaped. A bolt 21 is rotatably connected to the inner wall of the tension plate 20. The outer wall of the bolt 21 is rotatably connected to the inner wall of the tension plate 20. Two sets of bolts 21 are distributed on the outer wall of the tension plate 20. The outer wall of the bolt 21 on the side wall passes through the tension plate 20 and is threadedly connected to the fixing block 19. The outer wall of the bolt 21 on the lower wall passes through the tension plate 20 and is threadedly connected to the slider body 22. The outer wall of the slider body 22 is slidably connected to the inner wall of the base 23. A groove is opened inside the base 23. The shape of the groove is the same as that of the slider body 22.

[0030] The working principle is as follows: the support base 18 is first inserted into the inner wall of the base 23, and the fixing block 19 is slid into the groove of the support base 18. Bolt 21 passes through the tension plate 20, causing the slider body 22 to lock into the inner wall of the base 23, thus achieving a quick connection between the base 23 and the support base 18. During use, the bolt 21 pulls the fixing block 19 outward, locking it inside the groove of the support base 18, thus fixing the support base 18. This improves the support and stability of the support base 18 during use, preventing the bearing body 14 from shaking and causing wear when the shaft 17 rotates. During use, the bearing body 14 slides into the mounting groove 16 and the inner wall of the lower shell 1 via the outer wall of the bearing body 14. The mounting groove 16 allows for quick positioning, preventing misalignment of the bearing body 14 and potential detachment. During use, the temporary storage bottle 7, oil pipe 5, and mounting ring 6 are placed inside the first fixing ring 8. The second fixing ring 9, when rotating on the outer wall of the first fixing ring 8, seals the gap between the oil pipe 5 and the temporary storage bottle 7. The mounting rings on both sides further reduce the gap. During use, the clamping rod 10 flips and slides into the outer wall of the fixing plate 11. By pressing the pressure rod 13, the fixing plate 11 slides outward. Under the pull of the spring 12, when the pressure rod 13 is released, the fixing plate 11 slides into the inner wall of the clamping rod 10, quickly connecting the temporary storage bottle 7 and the oil pipe 5. During use, lubricating oil can be added to the oil tank 15 through the oil pipe 5. The temporary storage bottle 7 allows for monitoring of the lubricating oil level. The temporary storage bottle 7 passes through the lower shell 1 and the bearing body 14, allowing lubricating oil to flow into the oil tank 15. When the shaft 17 rotates, it lubricates the shaft 17. During use, the rotation of the shaft 17 lubricates the upper shell 2 with the lubricating oil. The upper bearing body 14 and the upper bearing body 14 allow the lubricating oil to flow back into the inner wall of the temporary storage bottle 7 through the oil pipe 5. This allows for observation of the lubricating oil usage during use, preventing a decrease in lubricity due to prolonged use, which could cause wear and damage to the bearing body 14. During use, the cooling pipe 3 and cooling chamber 4 can cool the shaft 17 and bearing body 14 when the shaft 17 rotates, preventing the shaft 17 from overheating due to high-speed friction during long-term operation, thus preventing deformation of the shaft 17 and bearing body 14 due to excessive temperature.
