Description

Technical Field

[0001] This utility model relates to the field of copper bushings, and in particular to an impact-resistant, oil-free graphite copper bushing. Background Technology

[0002] Oil-free graphite copper bushings are composed of copper and graphite, combining the strength and excellent thermal conductivity of copper with the lubricating properties of graphite. They are typically used in environments requiring high loads, low friction, and wear resistance.

[0003] When using oil-free graphite copper bushings inside marine equipment, the bushing body is mounted on a shaft, and graphite material in holes on the surface of the bushing body lubricates it, allowing for self-lubrication without oil. However, when the bushing body is used in high-impact environments, frequent impacts accelerate wear, shorten its service life, and lead to problems with the effectiveness of oil-free graphite copper bushings. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the copper bushing body is used in a high-impact working environment, frequent impacts exacerbate the wear of the copper bushing body, shorten its service life, and thus lead to problems with the performance of oil-free graphite copper bushings.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an impact-resistant oil-free graphite copper sleeve, including a copper sleeve body, a plurality of placement holes are opened on the surface of the copper sleeve body, a graphite body is placed inside the placement holes on the surface of the copper sleeve body, and an impact-resistant device is provided on the surface of the copper sleeve body. The impact-resistant device improves the impact resistance of the copper sleeve body through the impact-resistant sleeve.

[0006] Preferably, the impact-resistant device includes an installation component, an impact-resistant sleeve, and a plurality of connection holes on the surface of the impact-resistant sleeve. The installation component installs and fixes the impact-resistant sleeve to the surface of the copper sleeve body, and the size of the plurality of connection holes on the surface of the impact-resistant sleeve is adapted to the size of the placement holes on the surface of the copper sleeve body.

[0007] Preferably, the mounting assembly includes a mounting groove formed on the surface of the copper sleeve body, a magnet, an iron sheet, and a mounting plate. The magnet is disposed inside the mounting groove on the surface of the copper sleeve body. The magnet magnetically attracts the iron sheet fixed on one side of the mounting plate. One side of the mounting plate is connected to the impact-resistant sleeve.

[0008] Preferably, the mounting plate is smaller on the side furthest from the impact-resistant sleeve, making it easier to insert the mounting plate into the mounting groove on one side of the copper sleeve body.

[0009] Preferably, the mounting plate has control holes on its surface to allow it to be snapped into an external tool.

[0010] Preferably, the mounting assembly includes bolts that are inserted into one side of the mounting plate to connect with the copper sleeve body.

[0011] Preferably, a storage slot is provided on one side of the mounting plate to store the nuts of the bolts.

[0012] Preferably, an inclined groove is formed on the surface of the mounting groove on one side of the copper sleeve body to increase the inlet size of the mounting groove.

[0013] Preferably, the inner wall of the connecting hole on the surface of the impact-resistant sleeve is provided with a plurality of blocking blocks to block the graphite body inside the hole on the surface of the copper sleeve body.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] By using an impact-resistant device, an impact-resistant sleeve made of high-strength alloy can be installed and fixed onto the surface of the copper sleeve body, thereby improving the impact resistance of the copper sleeve body. When the copper sleeve body is used in a high-impact working environment, the wear rate of the copper sleeve body is reduced, thereby increasing the service life of the oil-free graphite copper sleeve and improving the performance of the oil-free graphite copper sleeve.

[0026] Example 1,

[0027] Figures 1 to 3 The illustration shows an impact-resistant, oil-free graphite copper bushing, comprising a copper bushing body 1 with several placement holes 2 on its surface. Graphite bodies 3 are placed inside the placement holes 2 on the surface of the copper bushing body 1. An impact-resistant device 4 is provided on the surface of the copper bushing body 1, and the impact-resistant device 4, through an impact-resistant sleeve 42, enhances the impact resistance of the copper bushing body 1. When using the oil-free graphite copper bushing inside marine equipment, the impact-resistant device 4 is installed on the surface of the copper bushing body 1 to improve its impact resistance. The copper bushing body 1 is then installed on the shaft of the marine equipment, and the graphite bodies 3 in the placement holes 2 on the surface of the copper bushing body 1 lubricate it, enabling the copper bushing body 1 to operate self-lubricatingly without lubricating oil.

[0028] Figures 1 to 3The impact-resistant device 4 shown includes a mounting component 41, an impact-resistant sleeve 42, and several connecting holes 43 on the surface of the impact-resistant sleeve 42. The mounting component 41 installs and fixes the impact-resistant sleeve 42 onto the surface of the copper sleeve body 1. The dimensions of the connecting holes 43 on the surface of the impact-resistant sleeve 42 are adapted to the dimensions of the placement holes 2 on the surface of the copper sleeve body 1. When using the impact-resistant sleeve 42, the mounting component 41 is used to fix the impact-resistant sleeve 42 onto the surface of the copper sleeve body 1. At this time, the connecting holes 43 on the surface of the impact-resistant sleeve 42 and the placement holes 2 on the surface of the copper sleeve body 1 are aligned to avoid affecting the placement of the graphite body 3. Then, the impact-resistant sleeve 42 improves the impact resistance of the surface of the copper sleeve body 1. By using the impact-resistant device 4, the impact-resistant sleeve 42, which is made of high-strength alloy, can be installed and fixed onto the surface of the copper sleeve body 1, thereby improving the impact resistance of the copper sleeve body 1. When the copper sleeve body 1 is used in a high-impact working environment, the wear rate of the copper sleeve body 1 is reduced, thereby increasing the service life of the oil-free graphite copper sleeve and improving the performance of the oil-free graphite copper sleeve.

[0029] Figures 1 to 3 The mounting assembly 41 shown includes a mounting groove 411 formed on the surface of the copper sleeve body 1, a magnet 412, an iron sheet 413, and a mounting plate 414. The magnet 412 is disposed inside the mounting groove 411 on the surface of the copper sleeve body 1. The magnet 412 magnetically attracts the iron sheet 413 fixed on one side of the mounting plate 414. One side of the mounting plate 414 is connected to the impact-resistant sleeve 42. When installing the impact-resistant sleeve 42, the impact-resistant sleeve 42 is moved so that the mounting plate 414 fixed on one side of the impact-resistant sleeve 42 comes into contact with the mounting groove 411 on one side of the copper sleeve body 1. Then, the iron sheet 413 fixed on one side of the mounting plate 414 is attracted and fixed by the magnet 412 fixed inside the mounting groove 411 on one side of the copper sleeve body 1, thus completing the installation and fixation of the impact-resistant sleeve 42 on the surface of the copper sleeve body 1.

[0030] Figures 1 to 3 The mounting plate 414 shown is smaller on the side furthest from the impact-resistant sleeve 42, making it easier to insert into the mounting groove 411 on one side of the copper sleeve body 1. This smaller size on the side of the mounting plate 414 allows for easier access to the mounting groove 411 on the copper sleeve body 1, facilitating quick installation and fixation of the impact-resistant sleeve 42 onto the surface of the copper sleeve body 1. A control hole 415 is provided on the surface of the mounting plate 414 to allow for engagement with external tools. This control hole 415 allows external tools to pass through and engage with the mounting plate 414, facilitating subsequent removal of the mounting plate 414 from the mounting groove 411 on the copper sleeve body 1 for replacement of the impact-resistant sleeve 42.

[0031] Working principle: When using oil-free graphite copper bushings inside marine equipment, the mounting component 41 in the impact-resistant device 4 fixes the impact-resistant bushing 42 to the surface of the copper bushing body 1. At this time, the connecting hole 43 on the surface of the impact-resistant bushing 42 is aligned with the placement hole 2 on the surface of the copper bushing body 1 to avoid affecting the placement of the graphite body 3, thereby improving the impact resistance of the copper bushing body 1. Then, the copper bushing body 1 is installed on the shaft of the marine equipment. The graphite body 3 in the placement hole 2 on the surface of the copper bushing body 1 lubricates the copper bushing body 1, allowing it to be used self-lubricated without lubricating oil. When installing the impact-resistant bushing 42, the impact-resistant bushing 42 is moved so that the mounting plate 414 fixed on one side of the impact-resistant bushing 42 contacts the mounting groove 411 on one side of the copper bushing body 1. Then, the iron piece 413 fixed on one side of the mounting plate 414 is attracted and fixed by the magnet 412 fixed inside the mounting groove 411 on one side of the copper bushing body 1, thus completing the installation and fixation of the impact-resistant bushing 42 on the surface of the copper bushing body 1.

[0032] Example 2,

[0033] Figures 4 to 6 The mounting assembly 41 shown includes a bolt 416, which is inserted into one side of the mounting plate 414 to connect with the copper sleeve body 1. The mounting plate 414 on one side of the impact-resistant sleeve 42 is inserted into the mounting groove 411 of the copper sleeve body 1, and then the bolt 416 is rotated to thread the bolt 416 through the mounting plate 414 and fix it to the copper sleeve body 1, thereby quickly completing the installation and fixation of the impact-resistant plate on the copper sleeve body 1.

[0034] Figures 4 to 6 A storage groove 417 is provided on one side of the mounting plate 414 to store the nuts of the bolts 416. This storage groove 417 on one side of the mounting plate 414 helps to store the nuts of the bolts 416, preventing damage to the nuts and facilitating subsequent removal of the bolts 416 for replacement of the impact-resistant sleeve 42, thus improving the performance of the bolts 416. A beveled groove 418 is provided on the surface of the mounting groove 411 on one side of the copper sleeve body 1 to increase the inlet size of the mounting groove 411. This beveled groove 418 on the surface of the mounting groove 411 on one side of the copper sleeve body 1 increases the inlet size of the mounting groove 411, making it easier for the mounting plate 414 to be inserted into the mounting groove 411 on one side of the copper sleeve body 1.

[0035] Figures 4 to 6 The impact-resistant sleeve 42 shown has several blocking blocks 44 on the inner wall of the connecting hole 43 to block the graphite body 3 inside the placement hole 2 on the surface of the copper sleeve body 1. The blocking blocks 44 are fixed to the inner wall of the connecting hole 43 on the surface of the impact-resistant sleeve 42 to limit the position of the graphite body 3 inside the placement hole 2 on the surface of the copper sleeve body 1, allowing the graphite body 3 to be placed more stably inside the placement hole 2 on the surface of the copper sleeve body 1 for use.

[0036] Working principle: When installing the impact-resistant sleeve 42, the mounting plate 414 on one side of the impact-resistant sleeve 42 is inserted into the mounting groove 411 with the inclined groove 418 of the copper sleeve body 1. Then, the bolt 416 is rotated so that the bolt 416 passes through the mounting plate 414 and is threadedly fixed to the copper sleeve body 1. At this time, the nut of the bolt 416 is stored and protected by the storage groove 417 of the mounting plate 414, so as to quickly complete the installation and fixing of the impact-resistant plate on the copper sleeve body 1.
