Description

Technical Field

[0001] This application relates to the field of bearing technology, and more specifically, to a high-toughness bearing. Background Technology

[0002] Bearings are used in mechanical transmission to fix the relative motion of rotating shafts and other components, providing support or guidance. Based on the frictional properties of the moving elements, they can be divided into sliding bearings and rolling bearings. Their performance determines the precision, performance, lifespan, and reliability of the host machine. Bearings often operate under harsh environments such as alternating loads of friction and compressive stress, as well as corrosive media. They must withstand not only various instantaneous impact forces but also high alternating stresses, which can lead to fatigue cracks and frictional damage, and in severe cases, even bearing ring fracture.

[0003] A search revealed a patent number disclosing a high-toughness bearing, relating to the field of high-toughness bearing technology. The bearing includes an inner ring with a rectangular groove on its inner edge for mounting pins on an edge shaft. A bearing retainer is fitted onto the outer surface of the inner ring, and multiple needle rollers are fitted onto the retainer. The needle rollers have a carburized thickness of 0.3 to 0.5 mm and are internally soft. Multiple lubrication grooves are formed on the surface of the needle rollers. The needle rollers are interference-fitted with the outer ring. During rotation, the carburized treatment of the needle rollers effectively ensures high toughness and reduces wear during use. The internal toughness of the needle rollers is better than their external toughness, preventing breakage under external impact and significantly improving bearing efficiency.

[0004] Although the aforementioned patent achieves the goal of preventing needle breakage through carburizing treatment, the friction between the needle and the inner and outer rings is dry. While the surface hardness of the needle increases after carburizing, the dry friction significantly increases the coefficient of friction, leading to rapid wear at the contact points between the needle and the inner and outer rings. The carburized layer of the needle will peel off and scratch, and scratches and pits will appear on the surfaces of the inner and outer rings, resulting in a rapid decrease in fitting accuracy and thus increasing equipment maintenance costs.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-4 A high-toughness bearing includes an outer ring 1 and an inner ring 2. The inner ring 2 is provided with a plurality of needle rollers 3. The outer ring 1 is provided with a lubrication assembly and a control assembly.

[0030] The lubrication assembly includes a wiping cotton 8, and the number of wiping cotton 8 is set to be multiple. The multiple wiping cotton 8 are arranged in a one-to-one correspondence with the multiple needle rollers 3. The multiple wiping cotton 8 are used to wiping lubricate the multiple needle rollers 3.

[0031] Reference Figures 1-4 An oil storage cavity 4 is provided inside the outer ring 1. Multiple through holes 5 are provided on one side of the oil storage cavity 4. The multiple through holes 5 are arranged in a ring array along the axis of the outer ring 1. An intercepting plate 6 is provided on the side of the multiple through holes 5 away from the oil storage cavity 4. A dispersion hole 7 is provided inside the intercepting plate 6. The number of dispersion holes 7 is set to multiple and the multiple dispersion holes 7 are evenly distributed. Multiple wiping cotton 8 are respectively connected to one side of the corresponding intercepting plate 6. The side of the multiple wiping cotton 8 away from the corresponding intercepting plate 6 is in contact with the needle roller 3.

[0032] The lubrication assembly lubricates the surface of the needle roller 3. Specifically, the lubricating oil is stored in the oil reservoir 4. When the bearing starts to operate, due to the rolling of the needle roller 3 and the centrifugal force, the lubricating oil in the oil reservoir 4 flows out through multiple through holes 5 arranged in a ring array along the axis of the outer ring 1. When the outflowing lubricating oil passes through the interceptor plate 6, it is further dispersed by the dispersion holes 7, so that the lubricating oil can be more evenly distributed on one side of the interceptor plate 6. The wiping cotton 8 connected to one side of the interceptor plate 6 absorbs the dispersed lubricating oil. As the needle roller 3 rotates continuously, the wiping cotton 8 evenly coats the surface of the needle roller 3 with the absorbed lubricating oil. Since the wiping cotton 8 is made of soft, fine, oil-absorbing, and wear-resistant polyester fiber cotton, the lubrication of the needle roller 3 is achieved.

[0033] The lubrication components can deliver lubricating oil to the needle rollers 3 with precision, and the wiping cotton 8 helps to distribute the lubricating oil evenly, reducing lubricating oil waste, improving lubrication effect, ensuring stable and smooth operation of the bearing under high toughness requirements, reducing problems such as component wear and heat generation caused by friction, extending the service life of the bearing, and improving the reliability and durability of the entire device. In addition, good lubrication and a uniform oil film can avoid vibration and noise caused by gap changes due to poor lubrication, making the bearing run more smoothly and quietly, and improving the comfort and stability of equipment operation.

[0034] Reference Figures 1-5 The control assembly includes a control plate 10. A groove 9 is provided inside the outer ring 1, and the control plate 10 is slidably connected to the groove 9. Multiple through-holes 11 are provided inside the control plate 10, and the multiple through-holes 11 are arranged in a circular array along the axis of the control plate 10. The width of the multiple through-holes 11 is adapted to the width of the multiple through holes 5. A toggle ring 12 is provided on one side of the outer ring 1. One side of the control plate 10 passes through one side of the outer ring 1 and is fixedly connected to the toggle ring 12. Multiple grooves 13 are provided inside the toggle ring 12, and multiple marking grooves 14 are provided on the outer wall of the outer ring 1. The multiple grooves 13 and the multiple marking grooves 14 are arranged in a one-to-one correspondence.

[0035] The amount of oil flowing from the oil reservoir 4 to the wiping cotton 8 can be controlled at any time by the control component. Specifically, when it is necessary to control the amount of oil flowing from the oil reservoir 4 to the wiping cotton 8, it can be achieved by rotating the actuating ring 12. Since the actuating ring 12 is fixedly connected to the control plate 10, rotating the actuating ring 12 will cause the control plate 10 to slide in the slide groove 9. Since the control plate 10 and the outer ring 1 are equipped with seals, the sealing of the outer ring 1 can be guaranteed. The control plate 10 has multiple through holes 11 arranged in a ring array along its axis and whose width is adapted to the through hole 5. When the actuating ring 12 is rotated, the through holes 11 are connected to the outer ring 1. When the through holes 5 are completely aligned, the oil in the oil storage chamber 4 can flow to the wiping cotton 8 through the through holes 5 and the through opening 11 to the maximum extent, through the dispersion holes 7 of the interceptor plate 6, and at this time the flow rate of the lubricating oil is the largest. When the rotating toggle ring 12 makes the through opening 11 partially aligned with the through hole 5, the flow rate of the lubricating oil will decrease accordingly. When the through opening 11 and the through hole 5 are completely misaligned, the flow channel of the lubricating oil is cut off. At this time, the oil in the oil storage chamber 4 cannot flow to the wiping cotton 8. Furthermore, by observing whether the groove 13 on the toggle ring 12 and the marking groove 14 on the outer wall of the outer ring 1 are aligned, the alignment state of the through opening 11 and the through hole 5 can be intuitively understood, thereby accurately controlling the flow rate of the lubricating oil.

[0036] The supply of lubricating oil can be precisely adjusted by the control components. By accurately controlling the amount of lubrication, excessive wear of bearing components caused by insufficient lubrication can be effectively prevented, as well as problems such as oil leakage, contamination, and component corrosion that may be caused by excessive lubrication. This helps to extend the service life of bearings, reduce the frequency of equipment maintenance and replacement, and thus reduce the operating and maintenance costs of equipment. Moreover, different working environments and conditions have different requirements for bearing lubrication. For example, in high-temperature environments, lubricating oil may evaporate or deteriorate more quickly, requiring an appropriate increase in the amount of lubrication; while in clean, low-temperature environments, the amount of lubrication can be appropriately reduced. The design of the control components allows the bearings to flexibly adapt to various working conditions and environments, improving the versatility and adaptability of the bearings.

[0037] Reference Figures 1-3 The outer wall of the outer ring 1 is provided with an oil replenishment hole 15, which is connected to the oil storage cavity 4. A sealing plug 16 is provided on one side of the oil replenishment hole 15. The oil replenishment hole 15 and the sealing plug 16 are in an interference fit and are engaged with each other.

[0038] The oil replenishment hole 15 and the sealing plug 16 facilitate the replenishment of lubricating oil in the oil storage chamber 4 when it is insufficient. The interference fit and snap-fit ​​method can effectively prevent lubricating oil leakage and ensure a stable lubrication environment inside the bearing.

[0039] Working principle: First, lubricating oil is stored in the oil reservoir 4. When the bearing starts to operate, due to the rolling of the needle rollers 3 and the action of centrifugal force, the lubricating oil in the oil reservoir 4 will flow out through multiple through holes 5 arranged in a ring array along the axis of the outer ring 1. When the outflowing lubricating oil passes through the interceptor plate 6, it will be further dispersed by the dispersion holes 7, so that the lubricating oil can be more evenly distributed on one side of the interceptor plate 6. The wiping cotton 8 connected to one side of the interceptor plate 6 will absorb these dispersed lubricating oils. As the needle rollers 3 continue to rotate, the wiping cotton 8 will evenly coat the surface of the needle rollers 3 with the absorbed lubricating oil. Since the wiping cotton 8 is made of soft, fine, oil-absorbing and wear-resistant polyester fiber cotton, it can lubricate the needle rollers 3.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
