Anti-stuck shaft sleeve structure

Abstract

This utility model discloses an anti-jamming bushing structure, belonging to the field of bushing technology. It includes an anti-jamming bushing structure comprising a bushing body and an anti-jamming structure. The anti-jamming structure is located inside the bushing body and includes a transmission elastic ball, a driven gear, a brush, and a filter hole. The transmission elastic ball drives the driven gear to rotate, the driven gear drives the brush to rotate, and the filter hole filters waste material. The anti-jamming structure also includes an oil passage located inside the bushing body. Thus, while continuously supplying oil, impurities are filtered, and usable lubricating oil is further filtered from the impurities, avoiding lubrication failure and impurity blockage, achieving anti-jamming. This prevents the bushing structure from jamming due to impurity accumulation, which could lead to equipment downtime, parts damage, or even safety accidents. Simultaneously, it reduces maintenance and production costs.

Description

Technical Field

[0001] This application relates to the field of bushing technology, specifically to an anti-jamming bushing structure. Background Technology

[0002] A bushing is a cylindrical mechanical part that fits onto a shaft. It is usually made of wear-resistant materials such as bronze, cast iron, and plastic. It mainly supports the shaft, reduces friction between the shaft and fixed parts, positions the radial position of the shaft, and protects the shaft and mating surfaces through sliding contact with the shaft. As it is a wear part, the replacement cost after wear is low, and it is widely used in various rotating machinery.

[0003] With the development of industrial technology, the internal smoothness and regularity of bushings have been greatly improved. This significantly reduces the wear of the shaft when it rotates inside, allowing for the replacement of bushings and reducing production costs by replacing shaft wear with bushing wear. However, bushings currently on the market generally have the following technical problems in actual use:

[0004] In rotating machinery used in the production and processing of machine tools, automobiles, and construction machinery, traditional bushings are prone to wear and impurities due to foreign object intrusion and uneven application of lubricating oil, which can lead to lubrication failure and seizure. This can result in equipment downtime, parts damage, or even safety accidents, thereby increasing production costs. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-jamming bushing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an anti-jamming bushing structure, comprising a bushing body and an anti-jamming structure, characterized in that the anti-jamming structure is formed on the inner side of the bushing body;

[0007] The anti-jamming structure includes a transmission elastic ball, a driven gear, a brush, and a filter hole. The transmission elastic ball is used to drive the driven gear to rotate, the driven gear is used to drive the brush to rotate, and the filter hole is used to filter waste.

[0008] Optionally, the anti-jamming structure further includes an oil passage, which is opened on the inner side of the bushing body. A waste discharge port is opened on the outer side of the bushing body, and a sealing bolt is provided on the inner side of the waste discharge port. The sealing bolt is threadedly connected to the waste discharge port.

[0009] Optionally, an oiling space is provided on the inner side of the bushing body, an oil spraying rod is provided on the inner side of the oiling space, and multiple oil grooves are provided on the outer side of the oil spraying rod.

[0010] Optionally, the outer side of the oil tank is provided with multiple oil inlets, and the outer side of the oil spraying rod is provided with multiple oil spraying holes.

[0011] Optionally, the oil spraying rod has an oil storage space inside, which is connected to the oil inlet and the oil spraying hole. Both sides of the oil spraying rod are equipped with drive gears, and the outer side of the drive gears is equipped with transmission elastic balls.

[0012] Optionally, the outer side of the transmission elastic ball is provided with an elastic surface, the inner side of the bushing body is provided with a waste material slide, the waste material slide is connected to the oiling space, a brush is rotatably connected to the inner side of the waste material slide, and driven gears are installed on both sides of the brush.

[0013] Optionally, the driven gear meshes with the driving gear, a waste bin is provided on the inner side of the bushing body, the waste bin is connected to the waste slide, and multiple filter holes are provided at the bottom of the waste bin, with the oil passage being threaded.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] In this invention, the shaft rotates within the bushing body, its surface contacting the elastic surface of the transmission elastic ball, causing the transmission elastic ball to rotate. This, in turn, causes the driving gears on both sides to rotate synchronously. The driving gears mesh with the driven gears, driving the brush to rotate within the waste chute, simultaneously rotating the oil spraying rod. As the brush rotates, it filters the lubricating oil in the oil passage, carrying impurities to the waste chute. After the impurities accumulate, they flow into the waste bin. The impurities in the waste bin are filtered through the filter holes, and the lubricating oil contained therein flows out through the filter holes and back to the shaft. The driving gear then drives the oil spraying rod. During rotation, some of the lubricating oil carried on the brush is scraped off by the oil spraying rod and flows through the oil inlet to the oil storage space. The oil storage space buffers the flow to achieve uniform oil supply, and then the oil is sprayed onto the shaft surface and the inner wall of the bushing through the oil spraying holes to maintain continuous lubrication. In this way, impurities are filtered out while continuously supplying oil, and usable lubricating oil is further filtered out from the impurities, avoiding lubrication failure and impurity blockage, thus preventing jamming. This avoids the problem of the bushing structure jamming due to the accumulation of impurities, which could lead to equipment downtime, parts damage, or even safety accidents. In the same way, maintenance and production costs are reduced. Attached Figure Description

Detailed Implementation

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figure 1 - Figure 5

[0026] This utility model provides a technical solution: an anti-jamming bushing structure, including a bushing body 1 and an anti-jamming structure 2, characterized in that the anti-jamming structure 2 is opened on the inner side of the bushing body 1, and the anti-jamming structure 2 includes a transmission elastic ball 213, a driven gear 211, a brush 206 and a filter hole 216. The transmission elastic ball 213 is used to drive the rotation of the driven gear 211, the driven gear 211 is used to drive the brush 206 to rotate, and the filter hole 216 is used to filter waste.

[0027] Specifically, such as Figure 1-2As shown, in order to achieve the above objectives, this application provides the following technical solution: the anti-jamming structure 2 further includes an oil passage 201, which is opened on the inner side of the bushing body 1. A waste discharge port 202 is opened on the outer side of the bushing body 1. A sealing bolt 203 is provided on the inner side of the waste discharge port 202, and the sealing bolt 203 is threadedly connected to the waste discharge port 202.

[0028] During operation, when the shaft rotates within the bushing body 1, its surface contacts the elastic surface 214 of the transmission elastic ball 213, causing the transmission elastic ball 213 to rotate. This, in turn, causes the driving gears 212 on both sides to rotate synchronously. The driving gears 212 mesh with the driven gears 211, driving the brush 206 to rotate within the waste chute 204. Simultaneously, the brush 206 rotates, filtering the lubricating oil in the oil passage 201. This causes impurities to be pushed towards the waste chute 204. As the impurities accumulate, they eventually flow into the waste bin 205. The impurities accumulated in the waste bin 205 are filtered through the filter holes 216, and the lubricating oil contained within them is filtered out and flows back to the shaft.

[0029] Specifically, such as Figure 1-3 As shown, an oiling space 207 is provided on the inner side of the bushing body 1, an oil spraying rod 208 is provided on the inner side of the oiling space 207, a plurality of oil grooves 209 are provided on the outer side of the oil spraying rod 208, a plurality of oil inlets 215 are provided on the outer side of the oil grooves 209, and a plurality of oil spraying holes 210 are provided on the outer side of the oil spraying rod 208.

[0030] Specifically, such as Figure 2-5 As shown, the oil spraying rod 208 has an oil storage space inside, which is connected to the oil inlet 215 and the oil spraying hole 210. Both sides of the oil spraying rod 208 are equipped with driving gears 212. The outer side of the driving gears 212 is equipped with transmission elastic balls 213. The outer side of the transmission elastic balls 213 is provided with elastic surfaces 214. The inner side of the bushing body 1 is provided with a waste material slide 204, which is connected to the oiling space 207. The inner side of the waste material slide 204 is rotatably connected with a brush 206. Both sides of the brush 206 are equipped with driven gears 211, which mesh with the driving gears 212. The inner side of the bushing body 1 is provided with a waste material bin 205, which is connected to the waste material slide 204. The bottom of the waste material bin 205 is provided with multiple filter holes 216. The oil passage 201 is threaded.

[0031] During operation, when the drive gear 212 drives the oil spraying rod 208 to rotate, some of the lubricating oil carried on the brush 206 is scraped off by the oil spraying rod 208 and flows through the oil inlet 215 to the oil storage space. The oil storage space buffers and achieves a uniform effect. Then, it is sprayed onto the shaft surface and the inner wall of the bushing through the oil spraying hole 210 to maintain continuous lubrication. In this way, impurities are filtered while the oil is continuously supplied, and then the impurities are further filtered to obtain usable lubricating oil, avoiding lubrication failure and impurity blockage, and achieving anti-seize.

[0032] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
