Description

Technical Field

[0001] This utility model relates to the field of bushing structure technology, specifically to a deformation-resistant self-lubricating bushing structure. Background Technology

[0002] As a fundamental component in mechanical transmission systems, bushings play a crucial role in rotating equipment. Their main functions are to support the shaft, reduce friction and wear, and bear radial loads from the shaft. Most bushings rely on external oil supply systems or periodic manual oiling to maintain lubrication, which not only increases the complexity of equipment maintenance but also limits their applicability in special environments to some extent.

[0003] Existing bushing technology still has significant shortcomings in dealing with harsh operating conditions such as high speed, heavy load, and high temperature. On the one hand, ordinary bushings have limited resistance to deformation and are prone to plastic deformation or fatigue damage under continuous high load operation, leading to an increase in the clearance between the shaft and the bushing, affecting transmission accuracy and generating vibration and noise. On the other hand, common self-lubricating designs often rely on a single lubricating material or a simple oil reservoir structure, making it difficult to maintain a stable lubrication effect during long-term operation; especially after the lubricant is depleted, if it is not replenished in time, it will aggravate the wear of the friction pair and even cause seizing failure. To address these issues, we propose a deformation-resistant self-lubricating bushing structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a deformation-resistant self-lubricating bushing structure. Through the synergistic effect of the flow guiding component, the first lubrication component, the second lubrication component and the reinforcement component, it can achieve uniform distribution of lubricating oil, continuous self-lubrication, improved structural strength and convenient maintenance, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant self-lubricating bushing structure, comprising a bushing body and a flow guiding component; Bushing body: A first lubrication component and a second lubrication component are mounted on the surface of the bushing body, and a reinforcing component is mounted on the surface of the bushing body; The flow guiding assembly includes flow guiding holes, annular flow guiding grooves, and strip flow guiding grooves. The bushing body has evenly distributed flow guiding holes in the middle of its circumferential surface. The bushing body also has evenly distributed annular flow guiding grooves and strip flow guiding grooves inside. All the flow guiding holes, annular flow guiding grooves, and strip flow guiding grooves are interconnected. By setting the flow guiding assembly, the lubricating oil inside the storage ring is guided, so that the lubricating oil can flow evenly into the interior of the bushing body.

[0006] Furthermore, the first lubrication assembly includes a storage ring, an internal threaded ring, and a sealing bolt. The storage ring is fixed in the middle of the circumferential surface of the bushing body. An annular storage cavity is formed inside the storage ring, and the annular storage cavity communicates with all the guide holes. A fixing hole is formed on the right side of the upper end of the storage ring. An internal threaded ring is fixed inside the fixing hole. The internal thread of the internal threaded ring is connected to the sealing bolt. The annular storage cavity is sealed by setting the sealing bolt. When oil needs to be added, the sealing bolt can be removed, and then the lubricating oil can be easily replenished.

[0007] Furthermore, the second lubrication assembly includes a fixing block, an oblique connecting hole, a graphite column, a connecting plate, a spring, a turntable, and a fastening bolt. A mounting hole is provided at the left end of the upper side of the storage ring, and a fixing block is fixed inside the mounting hole. An oblique connecting hole is provided on the right side of the fixing block.

A turntable is fixed to the left end of the spring, and a fastening bolt is rotatably connected to the left end of the turntable. The fastening bolt is threaded into the left end of the oblique connecting hole. By setting up the second lubrication assembly, the graphite column can tightly contact the shaft inside the bushing body during use, thus lubricating the shaft.

[0008] Furthermore, the reinforcing component includes reinforcing rings, reinforcing ribs, and protective tubes. Two corresponding reinforcing rings are fitted onto the upper and lower ends of the bushing body surface. The reinforcing rings have evenly distributed reinforcing ribs fixed inside. The bushing body has a strip-shaped support groove on its circumference, and the reinforcing ribs are slidably connected inside the strip-shaped support groove. The lower reinforcing ring has evenly distributed threaded grooves on its circumference, and a protective tube is threaded onto its circumference. By setting the reinforcing component, the strength of the bushing body is improved, and deformation is prevented.

[0009] Furthermore, it also includes a fastening assembly, which includes fastening plates and fixing bolts. The upper end of the storage ring has three corresponding openings, and three corresponding fastening plates are fixed on the end face of the reinforcing ring. The six fastening plates are respectively snapped into the three openings. The circumferential surface of the storage ring has threaded holes, and fixing bolts are threaded into the threads of the threaded holes. The fixing bolts are connected to the corresponding two fastening plates. The two reinforcing rings are fixed by setting the fastening assembly.

[0010] Furthermore, a fixing ring is fixed to the upper end of the circumferential surface of the upper reinforcing ring, and the upper end of the fixing ring is provided with evenly distributed fixing holes. The fixing ring and fixing holes facilitate the installation of the bushing body.

Meanwhile, the second lubrication component 4 guides the graphite column 43 to continuously press against the shaft under the elastic force of the spring 45 through the fixing block 41 and the oblique connecting hole 42. The preload of the spring 45 is adjusted by the fastening bolt 47 to ensure that the graphite column 43 is always in contact with the shaft during operation, providing solid lubrication as a supplement, especially to prevent dry friction when the lubricating oil is insufficient. The reinforcement component 5 is embedded in the strip support groove of the bushing body 1 through the upper and lower reinforcement rings 51 and the reinforcement ribs 52, which enhances the overall structural rigidity and resists the risk of deformation under high load. The lower protective tube 53 provides additional protection. The fastening component 6 uses the fastening plate 61 and the fixing bolt 62 to firmly connect the reinforcement ring 51 to the storage ring 31 to ensure the stability of the component. The fixing ring 7 and the fixing hole 8 facilitate installation and fixation.
