Description

Technical Field

[0001] The utility model relates to the technical field of oil-free graphite bushings, in particular to an impact-resistant oil-free graphite bushing. Background Art

[0002] The oil-free graphite bushing is also called a self-lubricating bushing. It takes the bushing as the base body and punches small holes with orderly arrangement and appropriate size on the friction surface, and inserts graphite into these holes, thus forming the required oil-free graphite bushing with self-lubricating ability. Since the oil-free graphite bushing is a self-lubricating bushing, to achieve the required self-lubricating effect, the proportion of graphite must reach a certain level to achieve the self-lubricating effect. In the casting of oil-free graphite bushings, the proportion is 20%-30%. This proportion can ensure the strength of the bushing base body and at the same time achieve the lubricating effect. The oil-free graphite bushing has been widely used in various industries, and the main industries using it include some large-scale mechanical equipment such as construction machinery, textile machinery, ship machinery, mining machinery, metallurgical machinery, and rolling machinery.

[0003] When the oil-free graphite bushing slides during work, a graphite film is formed on the surface to achieve the lubrication function. This requires ensuring that the contact surface is smooth enough. First, when processing, it is necessary to ensure that the inner and outer walls of the oil-free graphite bushing are smooth enough, and during use, it is necessary to prevent the graphite blocks from shifting. If the graphite blocks shift, it will cause the contact surface to be uneven, and the oil-free graphite bushing may be impacted during use, and the impact force will drive the oil-free graphite bushing to vibrate, resulting in the loosening or shifting of the graphite blocks.

[0004] Therefore, there is an urgent need to provide an impact-resistant oil-free graphite bushing to solve the above problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that the impact-resistant structure of the existing oil-free graphite bushing is not convenient for disassembly. After the graphite is consumed, it needs to be maintained in time. After the graphite is consumed, the overall lubricity decreases, and the friction on the impact-resistant structure also increases. It is not convenient to maintain without disassembly.

[0006] To solve the above technical problem, a technical solution adopted by the utility model is: to provide an impact-resistant oil-free graphite bushing, including a lubricating component, the lubricating component forms a graphite film when sliding to reduce the friction force, an outer protection component is slidably connected to one side of the lubricating component, and a force unloading component is slidably connected inside the lubricating component;

The partition plate can cushion and relieve the force on the outside of the copper body, and the clamping blocks can ensure that the partition plate can be installed at a specified position, and the stability during impact will be increased after the partition plate is aligned with the copper body.

[0013] The present utility model is further configured as follows: The force-relieving component includes a backing plate, the backing plate is inserted into the cavity, a plurality of washers are embedded in the backing plate, the washers can make the graphite blocks more firm, and the possibility of falling off and being displaced during vibration is reduced. Two first insertion holes are symmetrically formed on one side of the backing plate.

Insert blocks 403 are provided on both sides of the bracket 401, and the insert blocks 403 are adapted to the first sockets 303. The bracket 401 is inserted into one side of the pad 301, and then the slide plate 402 is slid through the inside of the bracket 401 to calibrate the pad 301, so that the pad 301 can be aligned with the internal through hole of the copper body 101 during installation, which can assist in the installation of the pad 301.

[0038] A damping assembly 6 is provided on one side of the lubrication assembly 1, and the damping assembly 6 can be disassembled. Figure 9 As shown, the shock absorbing assembly 6 includes a bottom ring 601, which is fixedly connected to the slot 108, and a slip ring 602 is slidably connected to one side of the bottom ring 601. A second spring 603 is provided between the bottom ring 601 and the slip ring 602. The shock absorbing direction of the second spring 603 is different from that of the pad 301 and the partition 201, thereby expanding the overall unloading range.

The sliding plate 402 will slide along with the push plate 505. When the bracket 401 is inserted into one side of the backing plate 301, if the sliding plate 402 can pass through the bracket 401, it means that the backing plate 301 has been rotated to align with the copper body 101. After the clamping plate 501 slides into the inside of the groove 106, it can slide into the card slot 107 for storage, and when the bracket 401 can be inserted into the two second jacks 507, they can be stored together. When in use, the first spring 504 can eject the push plate 505 to enable the sliding plate 402 to slide, and when not in use, it can be hidden for convenient use next time.

Then the sliding plate 402 will be ejected from the groove 106. By sliding the sliding plate 402, it can be judged whether the backing plate 301 is installed in place. If the sliding plate 402 can pass through the bracket 401, it means that the holes on the backing plate 301 are aligned with the holes on the copper body 101. At this time, insert multiple graphite blocks through the partition plate 201, the copper body 101 and the backing plate 301 for installation. After receiving the bracket 401, the sliding plate 402 and the clamping plate 501 into the card slot 107, finally install the bottom ring 601 in the slot 108.
