Description

Technical Field

[0001] The present application relates to the technical field of bearings, and more specifically, to a high-strength wear-resistant bearing. Background Art

[0002] Rolling bearings are precision mechanical components that convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Currently, rolling bearings are mainly composed of an outer ring, an inner ring, balls and a cage, and some full ball rolling bearings do not have a cage.

[0003] In the prior art, since the outer ring in the bearing supports the rolling elements of the inner ring, the rolling elements will bring greater friction and pressure to the inner side of the outer ring during rolling operation, which is very likely to cause wear to the bearing ring. Wear will cause the surface roughness of the bearing ring to increase, the friction coefficient to increase, thereby increasing the friction during the operation of the bearing, making the operation of the bearing unstable and increasing the noise. Utility Model Content

[0004] In order to solve the above problems, the present application provides a high-strength wear-resistant bearing.

[0005] The high-strength wear-resistant bearing provided in this application adopts the following technical solution:

[0006] A high-strength wear-resistant bearing comprises an outer ring, an inner ring is arranged inside the outer ring, and a lubrication assembly is arranged inside the outer ring;

[0007] The lubrication component includes an oil-absorbing fiber, which is located inside the outer ring. The cross-section of the oil-absorbing fiber is a circular ring. An oil outlet ring is provided on the inner side of the oil-absorbing fiber. A plurality of oil seepage holes are opened inside the oil outlet ring. A plurality of extrusion blocks are provided on the outer side of the oil outlet ring. The plurality of extrusion blocks are located between the oil-absorbing fiber and the oil outlet ring.

[0008] Through the above technical solution, when the roller of the lubrication component rolls between the outer ring and the inner ring, the lubricant will be slowly discharged from the inside of the oil-absorbing fiber, forming a lubricating film in the rolling contact area, reducing the direct contact between the roller and the outer ring and the inner ring, thereby reducing friction and wear and extending the service life of the bearing.

[0009] Furthermore, a plurality of oil injection holes are provided inside the outer ring, the plurality of oil injection holes are located on the top of the oil-absorbing fiber, and a one-way valve is provided inside each oil injection hole.

[0010] Through the above technical solution, lubricating oil is added to the oil filling hole, and the lubricating oil is transported to the inside of the oil-absorbing fiber through the oil filling hole. The one-way valve inside the oil filling hole prevents the lubricating oil from flowing back.

[0011] Furthermore, a retaining frame is provided between the outer ring and the inner ring, a plurality of rollers are provided inside the retaining frame, and support grooves are provided inside the outer ring and the inner ring.

[0013] Through the above technical solution, the silent pad can reduce the vibration and noise of the bearing during operation, which helps to maintain more stable lubrication conditions. Stable lubrication conditions can reduce friction and provide better lubrication effects, thereby reducing the friction and wear of the bearing.

[0014] Furthermore, the oil outlet ring is located in the support groove inside the outer ring, and the oil outlet ring and the oil absorbing fiber are located between the roller and the outer ring.

[0015] Furthermore, the top and bottom of the outer ring are both provided with sound insulation sealing covers, and the top and bottom of the outer ring and the inner ring are both provided with a plurality of jacks.

[0016] Through the above technical solution, the sound insulation sealing cover prevents the lubricating oil between the outer ring and the inner ring from leaking out.

[0017] Furthermore, a plurality of plug rods are fixedly connected to the opposite sides of the two sound insulation sealing covers, and the plurality of plug rods are respectively plugged into the corresponding plug holes.

[0018] Through the above technical solution, when installing the sound insulation sealing cover, the plug rod is inserted into the inside of the socket, and when disassembling, it is only necessary to pull out the sound insulation sealing cover, which is convenient for disassembly and installation.

[0019] Furthermore, the inner surface of the outer ring, the outer surface of the inner ring and the surface of the roller are all plated with a nickel alloy coating.

[0020] Through the above technical solution, the nickel alloy plating can provide higher surface hardness and wear resistance, reduce the wear on the surface of bearing parts, help extend the service life of the bearing, and improve its operating efficiency.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] (1) The utility model provides a lubricating assembly so that when the roller rolls between the outer ring and the inner ring, the lubricant is slowly discharged from the inside of the oil-absorbing fiber, forming a lubricating film in the rolling contact area, thereby reducing the direct contact between the roller and the outer ring and the inner ring, thereby reducing friction and wear, and extending the service life of the bearing;

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0032] Reference Figure 1-Figure 5 A high-strength wear-resistant bearing comprises an outer ring 1, an inner ring 2 is arranged inside the outer ring 1, and a lubrication component is arranged inside the outer ring 1;

[0033] The lubrication component includes an oil-absorbing fiber 11, which is located inside the outer ring 1. The cross-section of the oil-absorbing fiber 11 is circular. An oil outlet ring 9 is provided on the inner side of the oil-absorbing fiber 11. A plurality of oil seepage holes are opened inside the oil outlet ring 9. A plurality of extrusion blocks 10 are provided on the outer side of the oil outlet ring 9. The plurality of extrusion blocks 10 are located between the oil-absorbing fiber 11 and the oil outlet ring 9.

[0034] By setting the lubrication component, when the roller 8 rolls between the outer ring 1 and the inner ring 2, the lubricant will be slowly discharged from the inside of the oil-absorbing fiber 11, forming a lubricating film in the rolling contact area, reducing the direct contact between the roller 8 and the outer ring 1 and the inner ring 2, thereby reducing friction and wear and extending the service life of the bearing.

[0035] When the roller 8 rolls, it will squeeze the oil ring 9 to a certain extent. When the oil ring 9 is squeezed, it will squeeze the oil-absorbing fiber 11 through the squeezing block 10. The lubricating oil inside the oil-absorbing fiber 11 will be squeezed out by the squeezing block 10 and flow into the surface of multiple rollers 8 through the oil seepage holes inside the oil ring 9, thereby increasing the lubrication effect and reducing friction and wear.

[0036] When the speed of the roller 8 of the bearing increases, the extrusion pressure on the oil outlet ring 9 will increase slightly, resulting in an increase in the oil output of the oil-absorbing fibers 11 squeezed by the extrusion block 10, which can provide more lubricating oil and ensure that the bearing can still obtain sufficient lubrication when running at high speed.

[0037] Reference Figure 1-Figure 3 A plurality of oil injection holes 4 are provided inside the outer ring 1 , and the plurality of oil injection holes 4 are located on the top of the oil absorbing fiber 11 , and a one-way valve 13 is provided inside each of the oil injection holes 4 .

[0038] When the bearing is used, lubricating oil can be firstly added into the oil filling hole 4, and the lubricating oil is transported to the inside of the oil absorbing fiber 11 through the oil filling hole 4. The one-way valve 13 inside the oil filling hole 4 prevents the lubricating oil from flowing back.

[0039] Reference Figure 3-Figure 4 A retaining frame 6 is provided between the outer ring 1 and the inner ring 2, and a plurality of rollers 8 are provided inside the retaining frame 6. Support grooves are provided inside the outer ring 1 and the inner ring 2, and the plurality of rollers 8 are rollingly connected with the support grooves inside the outer ring 1 and the inner ring 2. A silent pad 7 is provided on the inner side of the support groove inside the inner ring 2, and the silent pad 7 is located between the inner ring 2 and the roller 8.

[0040] The silent pad 7 can reduce the vibration and noise of the bearing during operation, and help maintain a more stable lubrication condition. Stable lubrication conditions can reduce friction and provide better lubrication effect, thereby reducing the friction and wear of the bearing.

[0041] Reference Figure 1-Figure 4The oil outlet ring 9 is located in the supporting groove inside the outer ring 1, the oil outlet ring 9 and the oil absorbing fiber 11 are located between the roller 8 and the outer ring 1, the top and bottom of the outer ring 1 are provided with sound insulation sealing covers 3, the top and bottom of the outer ring 1 and the inner ring 2 are provided with multiple plug holes 5, and the two sound insulation sealing covers 3 are fixedly connected to the opposite sides with multiple plug rods 12, and the multiple plug rods 12 are respectively plugged into the corresponding plug holes 5.

[0042] The soundproof sealing cover 3 is provided to prevent the lubricating oil between the outer ring 1 and the inner ring 2 from leaking out. When installing the soundproof sealing cover 3, the insert rod 12 is inserted into the inside of the insertion hole 5. When disassembling, the soundproof sealing cover 3 only needs to be pulled out.

[0043] Reference Figure 1-Figure 5 The inner surface of the outer ring 1, the outer surface of the inner ring 2 and the surface of the roller 8 are all plated with a nickel alloy layer.

[0044] Nickel alloy plating can provide higher surface hardness and wear resistance, reduce wear on the surface of bearing components, help extend the service life of bearings, and improve their operating efficiency.

[0045] Working principle: When the roller 8 inside the bearing rotates, the oil ring 9 will be squeezed to a certain extent. When the oil ring 9 is squeezed, the oil-absorbing fiber 11 will be squeezed through the squeezing block 10. The lubricating oil inside the oil-absorbing fiber 11 will be squeezed out by the squeezing block 10 and flow into the surface of multiple rollers 8 through the oil seepage holes inside the oil ring 9, thereby increasing the lubrication effect and reducing friction and wear. When the speed of the roller 8 of the bearing increases, the squeezing force on the oil ring 9 will increase slightly, thereby increasing the amount of oil squeezed out of the oil-absorbing fiber 11 through the squeezing block 10, which can provide more lubricating oil and ensure that the bearing can still get sufficient lubrication when running at high speed.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
