Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a support roller and working machinery. Background Technology

[0002] Track rollers are core components of tracked vehicles such as excavators and bulldozers. On one hand, they bear the main weight of the vehicle and transfer the load to the ground via the tracks, ensuring stable movement in complex terrain and preventing localized sinking due to concentrated weight. On the other hand, track rollers help the tracks maintain their correct trajectory, preventing lateral deviation or slippage. Track rollers work in conjunction with drive sprockets and guide sprockets to ensure smooth, cyclical operation of the tracks.

[0003] Currently, track rollers mainly consist of components such as the roller body, axle, end caps, bearings, and floating oil seals. Lubricating oil is injected inside to reduce friction and wear between the axle and bearings. However, in actual use, various impurities easily accumulate inside track rollers: for example, iron filings remaining on the surface of components such as the roller body are difficult to thoroughly clean during the initial assembly stage; in addition, during long-term operation, wear of internal components can produce metal powders such as iron powder and copper powder. When these impurities mix with the lubricating oil, they lead to decreased lubrication performance, accelerated wear of internal components, and shortened service life. Utility Model Content

[0046] The following is combined Figures 1 to 5 This describes the support roller and working machinery according to embodiments of the present utility model.

[0047] According to embodiments of this utility model, in one aspect, a support roller is provided, suitable for application on tracked construction machinery, such as excavators, bulldozers, and tracked cranes. Specifically, as... Figure 1 As shown, the support roller includes a wheel body 1, a bearing 2, a wheel axle 3, a magnetic adsorption device 4, and a first porous adsorption device 5. The wheel body 1 has an oil reservoir 101 for holding lubricating oil, optionally located in the middle of the wheel body 1. Specifically, the wheel body 1 includes a first wheel body 102 and a second wheel body 103, with opposite ends detachably connected, for example, by a threaded connection. The oil reservoir 101 is located at the connection point of the first wheel body 102 and the second wheel body 103. This facilitates disassembly and assembly, reducing subsequent maintenance costs.

[0048] like Figure 1 As shown, bearings 2 are positioned opposite each other on both sides of the oil storage cavity 101, and bearings 2 open into the oil storage cavity 101. A wheel axle 3 passes through the bearings 2, allowing the wheel body 1 to rotate relative to the wheel axle 3, and lubricating oil to flow into the connection between the wheel axle 3 and the bearings 2. A magnetic adsorption device 4 is disposed in the oil storage cavity 101 and connected to the inner wall of the oil storage cavity 101, allowing the magnetic adsorption device 4 to rotate synchronously with the wheel body 1, making full contact with the lubricating oil in the oil storage cavity 101 and adsorbing iron filings and other impurities from the lubricating oil. A first porous adsorption device 5 is disposed in the oil storage cavity 101 and connected to the inner wall of the oil storage cavity 101, allowing the first porous adsorption device 5 to rotate synchronously with the wheel body 1, making full contact with the lubricating oil in the oil storage cavity 101 and adsorbing copper powder and other impurities from the lubricating oil. Furthermore, the first porous adsorption device 5 and the magnetic adsorption device 4 are arranged at intervals along the circumference of the wheel shaft 3. Optionally, the first porous adsorption device 5 and the magnetic adsorption device 4 are symmetrically arranged on both sides of the wheel shaft 3. In this way, the two do not interfere with each other and work independently and stably, thereby improving the overall impurity treatment efficiency.

[0049] It should be noted that when the support roller is working, the axle 3 remains stationary, while the wheel body 1 rotates around the axle 3. Iron and copper powder generated by the wear of components such as the axle 3 and bearing 2, as well as iron filings from uncleaned surfaces, enter the lubricating oil. The lubricating oil flows with the rotation of the wheel body 1. When it approaches the magnetic adsorption device 4, the iron filings in the lubricating oil are magnetically attracted to the surface of the magnetic adsorption device 4. At the same time, when the lubricating oil in the oil storage chamber 101 flows to the surface of the first porous adsorption device 5, it uses the pore adsorption characteristics to capture copper powder and a small amount of iron powder that has not been magnetically attracted in the lubricating oil.

[0050] This configuration, by arranging a magnetic adsorption device 4 and a first porous adsorption device 5 within the oil storage chamber 101, allows iron powder generated by friction and wear of components during long-term operation, as well as iron filings remaining from incomplete cleaning of components during assembly, to be adsorbed onto the surface of the magnetic adsorption device 4. Simultaneously, copper powder generated by friction and wear of the bearing 2, along with a small amount of iron powder not adsorbed by the magnetic adsorption device 4, can be adsorbed onto the surface of the first porous adsorption device 5. This enhances the effectiveness of adsorption filtration and reduces subsequent maintenance costs. Furthermore, the magnetic adsorption device 4 and the first porous adsorption device 5 are located close to the parts where friction and wear occur, significantly improving the adsorption filtration effect, ensuring the cleanliness of the lubricating oil, significantly improving lubrication performance, and extending the service life of the support roller.

[0051] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, the magnetic adsorption device 4 includes a non-magnetic connector 401 and a magnetic adsorption component 402. One end of the non-magnetic connector 401 is connected to the inner wall of the oil storage cavity 101, and the other end of the non-magnetic connector 401 is connected to the magnetic adsorption component 402. Specifically, the non-magnetic connector 401 is cylindrical and extends axially along the wheel axle 3. One end of the non-magnetic connector 401 is fixedly installed on the inner wall of the oil storage cavity 101. The magnetic adsorption component 402 has a square structure and is arranged radially along the wheel axle 3. The sidewall of the magnetic adsorption component 402 is fixedly connected to the non-magnetic connector 401.

[0052] With this configuration, the magnetic adsorption component 402 can directly adsorb iron filings onto its surface. Furthermore, the non-magnetic connector 401 fixes the magnetic adsorption component 402 to the wheel body 1, preventing direct contact between the magnetic adsorption component 402 and the wheel body 1, which would cause the wheel body 1 and the wheel axle 3 to become magnetized and generate magnetism, thus adsorbing the iron filings onto the surfaces of the wheel body 1 and the wheel axle 3. This ensures the reliable operation of the magnetic adsorption device 4 and improves the filtration and purification effect on the lubricating oil.

[0053] Optionally, in some embodiments of this utility model, the magnetic adsorption element 402 is a ring structure, which can increase the contact area between the magnetic adsorption element 402 and the lubricating oil, thereby significantly enhancing the adsorption efficiency of the magnetic adsorption element 402 and improving the purification effect of the lubricating oil. At the same time, the ring structure matches the flow path of the lubricating oil, reducing fluid resistance.

[0054] Optionally, in some embodiments of this invention, the magnetic adsorption element 402 is a permanent magnet. Specifically, the magnetic adsorption element 402 can be a neodymium iron boron magnet, which has excellent magnetic properties, ensuring continuous and effective adsorption of metal powder, and has high magnetic energy density, allowing the adsorption device to be designed to be smaller and lighter, suitable for space-constrained scenarios. With this configuration, the permanent magnet can autonomously and stably generate a magnetic field without relying on electricity, current, or other external energy sources, enabling continuous adsorption of ferromagnetic impurities. Its adsorption performance is stable and reliable, and its service life is significantly extended, exhibiting excellent performance in both functional continuity and durability.

[0055] Optionally, in some embodiments of this utility model, the non-magnetic connector 401 is made of plastic or aluminum alloy. Both plastic and aluminum alloy are non-magnetic materials, which will not be magnetized by a magnetic field, nor will they interfere with or shield the magnetic field generated by the magnetic device. While ensuring a reliable connection with the wheel 1, they can also ensure stable magnetic field strength and unaffected adsorption range, thereby guaranteeing the purification efficiency of the magnetic adsorption component 402. Furthermore, plastic and aluminum alloy are relatively lightweight, which can reduce the rotational load and inertial resistance of the wheel 1, reduce wear on components such as the wheel axle 3 and bearing 2, and extend their overall service life. In addition, both plastic and aluminum alloy have good corrosion resistance, are adaptable to complex environments, and are low in cost and easy to process. Of course, in other embodiments, the non-magnetic connector 401 can also be made of other non-magnetic materials such as stainless steel.

[0056] Optionally, in some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the first porous adsorption device 5 includes a first mesh bracket 501 and a first porous material adsorption element 502. Specifically, the first mesh bracket 501 is connected to the inner wall of the oil storage cavity 101. Optionally, the first mesh bracket 501 is arranged radially along the axle 3, and the first mesh bracket 501 can be a planar mesh bracket or a curved mesh bracket. The first porous material adsorption element 502 is stacked on the surface of the first mesh bracket 501. It should be noted that the shape of the first porous material adsorption element 502 should be consistent with the shape of the first mesh bracket 501 to ensure that the two are tightly fitted and connected.

[0057] With this configuration, the first porous material adsorption element 502 uses its pore adsorption properties to capture copper powder generated by the wear of the bearing 2 and a small amount of iron powder in the lubricating oil that is not attracted by the magnet. At the same time, the first mesh bracket 501 can act as a fixing cage to fix the first porous material adsorption element 502, so that the first porous material adsorption element 502 maintains a stable structural shape. Its mesh structure allows the lubricating oil to pass through smoothly, while effectively reducing fluid resistance, taking into account both flowability and low resistance characteristics.

[0058] Optionally, in some embodiments of this utility model, the first mesh support 501 is a stainless steel mesh support. With this configuration, stainless steel, possessing excellent mechanical strength and rigidity, serves as the base material for the mesh support, stably supporting the first porous material adsorption element 502, preventing deformation of the support due to equipment vibration, fluid impact, etc., and effectively resisting rust and chemical corrosion, avoiding problems such as mesh blockage and structural embrittlement caused by rust, resulting in a long service life.

[0059] Optionally, in some embodiments of this invention, the first porous material adsorption element 502 is an adsorbent fiber cotton. When the lubricating oil in the oil storage chamber 101 flows to the surface of the first porous adsorption device 5, the adsorbent fiber cotton uses its fiber pores to adsorb and capture copper powder generated by the wear of the bearing 2, as well as a small amount of iron powder in the lubricating oil that has not been adsorbed by the magnet. With this configuration, the adsorbent fiber cotton is composed of countless fine interwoven fibers, forming a dense and interconnected porous structure with a large specific surface area and strong adsorption capacity. The fine pores firmly lock in the adsorbed impurities through capillary action and surface tension, achieving a dynamic balance of "adsorption during flow," ensuring both the normal flow of the lubricating oil and continuous purification of the medium.

[0060] Optionally, in some embodiments of this utility model, such as Figure 1 As shown, the support roller also includes an end cap 6, a floating oil seal 8, and a second porous adsorption device 9. The end cap 6 is located at the end of the axle 3, and there is a gap between the end cap 6 and the roller body 1. Specifically, the end cap 6 is sleeved on the axle 3, and the end cap 6 and the axle 3 are respectively provided with through holes arranged radially along the axle 3. A cylindrical pin 10 passes through the through hole to fix the end cap 6 and the axle 3 in place. A sealing ring 11, such as an O-ring, is provided between the end cap 6 and the axle 3 to achieve a sealed connection between the end cap 6 and the axle 3, thereby preventing internal lubricating oil from leaking to the outside and preventing external dust and other impurities from entering the support roller and causing wear of parts and contamination of lubricating oil.

[0061] like Figure 1As shown, the end cap 6 and the wheel body 1 form a floating seal chamber 7, and the floating oil seal 8 is disposed within the floating seal chamber 7. The second porous adsorption device 9 is disposed on the side of the floating oil seal 8 facing the wheel axle 3. The second porous adsorption device 9 is connected to the end cap 6 and is located below the wheel axle 3. It should be noted that when the support roller is working, the end cap 6 remains fixed, the second porous adsorption device 9 remains fixed to the end cap 6, and the bearing 2 is interference-fitted with the wheel body 1, rotating with the wheel body 1 during operation. Under normal conditions, there is a gap of 0.2mm-0.6mm between the end cap 6 and the bearing 2, preventing contact. However, when the support roller 1 is subjected to an off-center load from the track, the end cap 6 and the bearing 2 come into contact and rub against each other, generating iron and copper powder, which falls directly onto the surface of the second porous adsorption device 9 under the influence of gravity and lubricating oil. In addition, some copper and iron powder generated by the friction and wear between the wheel axle 3 and the bearing 2 also flows into the surface of the second porous adsorption device 9 with the lubricating oil. Thus, the second porous adsorption device 9 uses micropores to adsorb and capture copper and iron powder in the filtered lubricating oil.

[0062] With this configuration, the second porous adsorption device 9 can accurately adsorb iron and copper powder mixed into the lubricating oil after friction and wear of the end cap 6, axle 3, and bearing 2, thereby reducing wear on the floating oil seal 8 and significantly improving sealing performance. Simultaneously, the targeted arrangement of the second porous adsorption device 9 according to the location of metal powder generation further enhances adsorption and filtration efficiency.

[0063] Optionally, in some embodiments of this utility model, such as Figure 5 As shown, the second porous adsorption device 9 includes a second mesh bracket 901 and a second porous material adsorption element 902. Specifically, the second mesh bracket 901 is connected to the end cap 6, and the second porous material adsorption element 902 is stacked on the surface of the second mesh bracket 901. It should be noted that the shape of the second porous material adsorption element 902 should be consistent with the shape of the second mesh bracket 901 to ensure that the two are tightly fitted and connected.

[0064] With this configuration, the second porous material adsorbent 902 uses its pore adsorption properties to capture iron powder and copper powder mixed into the lubricating oil after friction and wear of the end cap 6, wheel axle 3 and bearing 2. At the same time, the second mesh bracket 901 can play a fixed support role to fix the second porous material adsorbent 902, ensuring the reliable operation of the second porous material adsorbent 902. Moreover, its unique mesh structure has both excellent permeability and flow conductivity, which can not only allow the lubricating oil to pass through quickly and smoothly, but also greatly reduce fluid resistance. While ensuring the efficient flow of the lubricating medium, it minimizes the obstruction to its flow.

[0065] Optionally, in some embodiments of this utility model, both the second mesh bracket 901 and the second porous material adsorption element 902 are arc-shaped structures. Specifically, both the second mesh bracket 901 and the second porous material adsorption element 902 are arc-shaped structures, and their centers coincide with the center line of the wheel axle 3, thereby achieving a precise match with the wheel axle 3 and constructing an envelope curve with excellent fit. This arrangement allows the second porous adsorption device 9 to form a tight fit with the wheel axle 3, which not only significantly enhances the adsorption effect but also provides convenient installation and effectively improves the compactness of the overall structure.

[0066] Optionally, in some embodiments of this utility model, the second mesh bracket 901 is a stainless steel mesh bracket. This design leverages the high strength and structural stability of stainless steel, ensuring the bracket provides reliable support, maintaining a stable lubricating oil flow path, and preventing structural failure from affecting the coordinated operation of the filtration and lubrication systems. Furthermore, it exhibits outstanding corrosion resistance, maintaining structural integrity over a long period in lubricating oil environments, thus reducing the frequency of filtration system maintenance due to bracket failure.

[0067] Optionally, in some embodiments of this invention, the second porous material adsorption element 902 is an adsorbent fiber cotton. When iron powder and copper powder mixed in with the lubricating oil after the end cap 6, axle 3, and bearing 2 rub against and wear, they flow onto the surface of the second porous adsorption device 9. The adsorbent fiber cotton uses its fiber pores to adsorb and capture the iron powder and copper powder generated by the friction and wear of the end cap 6, axle 3, and bearing 2. With this configuration, the adsorbent fiber cotton effectively improves its adsorption capacity through its microporous structure and fiber arrangement, and its pore structure allows the lubricating oil to flow smoothly, balancing adsorption and flowability.

[0068] Optionally, in some embodiments of this utility model, the magnetic adsorption device 4 is detachably connected to the inner wall of the oil storage cavity 101. Specifically, the non-magnetic connector 401 of the magnetic adsorption device 4 is fixedly connected to the inner wall of the oil storage cavity 101 by means of interference fit through a connecting hole or threaded connection.

[0069] Optionally, in some embodiments of this utility model, the first porous adsorption device 5 is detachably connected to the inner wall of the oil storage chamber 101. Specifically, the first mesh bracket 501 of the first porous adsorption device 5 can be fixedly connected to the inner wall of the oil storage chamber 101 by means of a snap-fit ​​structure or threaded connection.

[0070] Optionally, in some embodiments of this utility model, the second porous adsorption device 9 and the end cap 6 are detachably configured. Specifically, the second mesh bracket 901 of the second porous adsorption device 9 and the end cap 6 can be fixedly connected by means of a snap-fit ​​structure or threaded connection.

[0071] This design, with its detachable structure, allows for quick assembly and disassembly of the magnetic adsorption device 4, the first porous adsorption device 5, and the second porous adsorption device 9. This not only greatly facilitates subsequent maintenance and replacement work but also helps extend the overall service life of the device.

[0072] According to an embodiment of this utility model, another aspect provides a working machine, including the track roller as described in the various embodiments above. Optionally, the working machine is an excavator, bulldozer, crawler crane, etc. With this configuration, by arranging a magnetic adsorption device 4 and a first porous adsorption device 5 within the oil storage chamber 101, iron powder generated by friction and wear of components during long-term operation, as well as iron filings remaining due to uncleaned components during assembly, can all be adsorbed onto the surface of the magnetic adsorption device 4. Simultaneously, copper powder generated by friction and wear of the bearing 2, and a small amount of iron powder not adsorbed by the magnetic adsorption device 4, can be adsorbed onto the surface of the first porous adsorption device 5, thereby improving the effectiveness of adsorption filtration and reducing subsequent maintenance costs. Furthermore, the magnetic adsorption device 4 and the first porous adsorption device 5 are located close to the parts where friction and wear occur, which greatly improves the adsorption filtration effect, ensures the cleanliness of the lubricating oil, significantly improves lubrication performance, and extends the service life of the track roller. Its overall structure is simple, reducing maintenance frequency and lowering costs. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effects of the aforementioned track roller, and therefore will not be repeated here.

[0073] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
