Description

Technical Field

[0001] The invention relates to the technical field of bearings, in particular to an anti-corrosion nano-coated bearing. Background Art

[0002] Rolling bearings rely on rolling elements rolling in raceways to achieve relative motion. They have the advantages of low friction coefficient, low starting resistance, high efficiency, and high precision. Common rolling bearings include deep groove ball bearings, angular contact ball bearings, tapered roller bearings, cylindrical roller bearings, etc. Sliding bearings are bearings that work under sliding friction. They reduce friction and wear by forming a layer of lubricating oil film between the journal and the bearing seat. Sliding bearings have the advantages of large load-bearing capacity, stable operation, no noise, and impact resistance. They are suitable for high-speed, heavy-load, high-precision and other occasions. Nano-lubricants are lubricants with nano-materials as the main component. Compared with traditional lubricants, nano-lubricants have more efficient lubrication performance, longer service life and a wider range of use. They can effectively reduce the wear of the friction pair surface and increase the service life of rolling bearings.

[0003] The patent website announcement number CN 210371683 U discloses a bearing, including a plurality of concave bearing blocks and a bearing seat for fixing the plurality of concave bearing blocks; the plurality of concave bearing blocks are each provided with a concave hollow portion for mutually splicing to form a cylindrical inner cavity, and also includes a circular ring slide sleeved in the cylindrical inner cavity. The bearing has a simple structure, is easy to manufacture and has a low cost.

[0004] The applicant believes that the following disadvantages exist: the surface of the bearing is not sealed. When the bearing is running, if there is no seal, the internal grease will gradually be thrown out from the bearing gap due to centrifugal force, vibration and other factors, resulting in a reduction in the amount of grease and an inability to form an effective lubricating film, thereby increasing the friction of the bearing, affecting the normal use of the bearing and reducing the use effect of the bearing. Summary of the invention

[0005] The object of the present invention is to provide a corrosion-resistant nano-coated bearing to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a corrosion-resistant nano-coated bearing, comprising a support, a rolling mechanism is arranged inside the support, a sealing mechanism is arranged on the surface of the rolling mechanism, and mounting mechanisms are arranged on both sides of the support surface, and the mounting mechanisms are symmetrically arranged.

[0007] The sealing mechanism includes a seal, a fixing ring is fixedly connected to the sealing surface, a connecting plate is fixedly connected to the surface of the fixing ring, a limiting piece is fixedly connected to the side of the connecting plate facing away from the fixing ring, a circular hole groove is opened in the limiting piece, a limiting rod is inserted in the circular hole groove, a thread is arranged on the surface of the limiting rod, a locking nut is threadedly connected to the surface of the limiting rod, and the locking nut is tightly attached to the surface of the support.

[0008] Preferably, the number of the limit rods is several, and the limit rods are distributed in an equidistant ring shape, and the limit rods are of the same length. In the design and manufacturing process of the bearing, in order to ensure the effectiveness and stability of the seal, a limit rod is specially provided. The limit rod is usually made of high-strength and wear-resistant metal material, and is reasonably arranged around the bearing sealing structure through precise installation technology. When the sealing assembly is installed on the bearing, the limit rod can play its unique role in preliminarily limiting the seal. It cooperates with specific slots or protrusions on the seal to limit the displacement range of the seal to a certain extent, so that the seal can be maintained in the correct position in the initial installation state, preventing it from being offset or skewed during the installation process, thereby laying the foundation for achieving a good sealing effect in the subsequent process. In this way, even before the bearing is officially put into operation, the seal has been preliminarily fixed in an ideal position under the action of the limit rod, effectively improving the reliability of the entire bearing sealing system.

[0009] Preferably, the surface of the fixing ring is fixedly connected with a connecting block, a limiting groove is provided in the connecting block, a support member is inserted in the limiting groove, and the support member is arranged on one side of the seal. In the sealing protection system of the entire bearing, the support member and the connecting block play a key role. The support member is usually made of an alloy material with high strength and good toughness. Its shape is carefully designed and is generally a block structure with a specific curvature so that it can better fit the outer contour of the bearing. These support members are precisely installed in a specific position inside the bearing seat near the seal, and are tightly connected to the bearing seat by a firm fixing method.

[0010] Preferably, the rolling mechanism includes an outer ring, the limit rod is fixedly connected to the side of the outer ring, the support is fixedly connected to the outer surface of the outer ring, and the connecting plate is arranged on one side of the outer ring, responsible for bearing the load transmitted from the outside to the bearing, including radial load and axial load. These loads may come from the running parts of the machine equipment, external forces, etc. The outer ring needs to have sufficient strength and rigidity to withstand these forces to ensure the stability and reliability of the bearing and the entire equipment.

[0011] Preferably, a rolling body is rollingly connected inside the outer ring, a retaining frame is rotatably connected to the surface of the rolling body, the side of the rolling body facing away from the outer ring is fixedly connected to the inner ring, and the retaining frame is arranged between the inner ring and the outer ring. The rolling body can withstand the radial load on the bearing and evenly distribute the load between the inner ring and the outer ring of the bearing. Taking the automobile wheel hub bearing as an example, when the vehicle is driving, the weight of the wheel and the various forces exerted on the wheel by the road surface will generate radial loads, and the rolling body is responsible for reasonably transmitting and distributing these forces between the wheel hub (corresponding to the outer ring of the bearing) and the axle (corresponding to the inner ring of the bearing) to ensure the stability of the vehicle.

[0012] Preferably, the number of the rolling bodies is several, and the several rolling bodies are distributed in a ring shape with equal intervals.

[0013] Preferably, the mounting mechanism includes a transverse plate, which is fixedly connected to both sides of the support surface, the transverse plate surface is fixedly connected to a mounting plate, the mounting plate is fixedly connected to a fixing block on the side away from the transverse plate, the fixing block is threadedly connected to a fixing bolt, the fixing bolt is horizontally arranged, the number of the fixing bolt threads is two, and the two fixing bolts are symmetrically arranged.

[0014] Preferably, both sides of the support surface are fixedly connected with connecting parts, and the connecting parts pass through fixing bolts. The connecting parts are arranged on one side of the cross plate, and the fixing bolts are rotated inside to achieve a tight fixed connection with the external surface of the fixed object, thereby providing a stable support for the support, ensuring that the bearing remains stable at all times during the subsequent operation process, and providing a solid foundation for the normal operation of the equipment.

[0015] Compared with the prior art, the present invention provides a corrosion-resistant nano-coated bearing, which has the following beneficial effects: 1. The corrosion-resistant nano-coated bearing has significant advantages through the setting of a sealing mechanism and a seal that is easy to install and disassemble. In equipment with harsh working environments such as construction machinery and mining machinery, a large amount of dust, soil, sand and other solid particles are filled around. Once these impurities enter the bearing, they will directly increase the degree of wear of parts such as the bearing raceway, rolling elements and holders. As the wear continues to increase, the accuracy of the bearing will be greatly reduced and the service life will be severely shortened. Our sealing device can effectively prevent the invasion of these impurities, just like putting a layer of solid protective armor on the bearing to ensure its normal operation.

[0016] 2. The corrosion-resistant nano-coated bearing has a rolling mechanism. During operation, the working principle of the bearing is based on the characteristics of rolling friction. When the shaft starts to rotate, the inner ring that fits closely with the shaft also rotates synchronously, and the rolling body continues to roll on the raceway between the inner ring and the outer ring. Since the rolling friction coefficient is much smaller than the sliding friction coefficient, the shaft can rotate with a smaller friction torque when rotating. In this way, not only the energy loss is reduced, but also the mechanical efficiency is improved. Taking the automobile wheel hub bearing as an example, it is precisely because of the reasonable application of the rolling bearing that the wheel can remain smooth during rotation, effectively reducing the fuel consumption of the car during driving and improving the energy utilization efficiency.

[0017] 3. The anti-corrosion nano-coated bearing, through the installation mechanism, can achieve a tight fixed connection between the fixing bolts and the surface of the external fixed object by rotating the internal fixing bolts, thereby providing a stable support for the support, ensuring that the bearing remains stable during the subsequent operation process, and providing a solid foundation for the normal operation of the equipment.

[0018] 4. The corrosion-resistant nano-coated bearing is coated with an corrosion-resistant nano-coating on the surface of the bearing. The nano-coating has an extremely small particle size and a high specific surface area, and can form a uniform and dense protective film on the surface of the bearing, effectively blocking the contact between corrosive media such as air, moisture, acid and alkali and the bearing matrix, thereby significantly improving the corrosion resistance of the bearing. For example, in some humid or chemically corrosive industrial environments, such as electroplating workshops and offshore operating platforms, bearings coated with corrosion-resistant nano-coatings can resist the erosion of chloride ions, acid mist, etc., avoid rust and corrosion damage, and play a good protective role for the bearing.

[0025] Furthermore, the number of limit rods 22 is several, and the limit rods 22 are distributed in an equidistant ring shape, and the lengths of the limit rods 22 are the same. In the design and manufacturing process of the bearing, in order to ensure the effectiveness and stability of the seal 24, a limit rod 22 is specially provided. The limit rod 22 is usually made of high-strength and wear-resistant metal material, and is reasonably arranged around the bearing seal 24 structure through precise installation technology. When the seal 24 assembly is installed on the bearing, the limit rod 22 can play its unique role and perform preliminary positioning of the seal 24. It cooperates with specific slots or protrusions on the seal 24 to limit the displacement range of the seal 24 to a certain extent, so that the seal 24 can be kept in the correct position in the initial installation state, preventing it from being offset or skewed during the installation process, thereby laying the foundation for achieving a good sealing 24 effect in the subsequent process. In this way, even before the bearing is officially put into operation, the seal 24 has been initially fixed in an ideal position under the action of the limit rod 22, effectively improving the reliability of the entire bearing seal 24 system.

[0026] Furthermore, the surface of the fixing ring 23 is fixedly connected with a connecting block 27, and a limiting groove 26 is provided in the connecting block 27. A support member 21 is inserted in the limiting groove 26. The support member 21 is arranged on one side of the seal 24. In the seal 24 protection system of the entire bearing, the support member 21 and the connecting block 27 play a key role. The support member 21 is usually made of an alloy material with high strength and good toughness. Its shape is carefully designed, generally a block structure with a specific curvature, so that it can better fit the outer contour of the bearing. These support members 21 are precisely installed in a specific position inside the bearing seat near the seal 24, and are tightly connected to the bearing seat by a firm fixing method. Embodiment 2:

In the design and manufacturing process of the bearing, in order to ensure the effectiveness and stability of the seal 24, a limiting rod 22 is specially provided, and the limiting rod 22 is usually made of high-strength and wear-resistant It is made of metal material and is reasonably arranged around the bearing seal 24 structure through precise installation technology. When the seal 24 component is installed on the bearing, the limit rod 22 can play its unique role and perform preliminary positioning of the seal 24. It cooperates with specific grooves or protrusions on the seal 24 to limit the displacement range of the seal 24 to a certain extent, so that the seal 24 can be kept in the correct position in the initial installation state to prevent it from being offset or skewed during the installation process, thereby laying the foundation for achieving a good sealing 24 effect in the subsequent process. In this way, even before the bearing is officially put into operation, the seal 24 has been initially fixed in an ideal position under the action of the limit rod 22, effectively improving the reliability of the entire bearing seal 24 system. Furthermore, the rolling mechanism 3 includes an outer ring 34, a limiting rod 22 is fixedly connected to the side of the outer ring 34, a support member 21 is fixedly connected to the outer surface of the outer ring 34, and a connecting plate 28 is arranged on one side of the outer ring 34, which is responsible for bearing the load transmitted from the outside to the bearing, including radial load and axial load. These loads may come from the running parts of the machine equipment, external forces, etc. The outer ring 34 needs to have sufficient strength and rigidity to withstand these forces to ensure the stability and reliability of the bearing and the entire equipment.

[0028] Furthermore, a rolling element 33 is rollingly connected inside the outer ring 34, a retainer 32 is rotatably connected to the surface of the rolling element 33, the side of the rolling element 33 facing away from the outer ring 34 is fixedly connected to the inner ring 31, the retainer 32 is arranged between the inner ring 31 and the outer ring 34, and the rolling element 33 can bear the radial load on the bearing and evenly distribute the load between the inner ring 31 and the outer ring 34 of the bearing. Taking the automobile wheel hub bearing as an example, when the vehicle is running, the weight of the wheel and the various forces exerted on the wheel by the road surface will generate radial loads, and the rolling element 33 is responsible for reasonably transmitting and distributing these forces between the wheel hub (corresponding to the outer ring 34 of the bearing) and the axle (corresponding to the inner ring 31 of the bearing) to ensure the stability of the vehicle. The number of rolling elements 33 is set to be several, and the several rolling elements 33 are distributed in an annular shape with equal spacing. Embodiment three:

[0029] See also Figure 6 , and on the basis of the first and second embodiments, the rolling mechanism 3 further comprises an outer ring 34, a limit rod 22 is fixedly connected to the side of the outer ring 34, a support member 21 is fixedly connected to the outer surface of the outer ring 34, and a connecting plate 28 is arranged on one side of the outer ring 34, responsible for bearing the load transmitted from the outside to the bearing, including radial load and axial load. These loads may come from the running parts of the machine equipment, external forces, etc., and the outer ring 34 needs to have sufficient strength and rigidity to bear these forces to ensure the stability and reliability of the bearing and the entire equipment, a rolling body 33 is rollingly connected inside the outer ring 34, a retaining frame 32 is rotatably connected to the surface of the rolling body 33, and an inner ring 31 is fixedly connected to the side of the rolling body 33 away from the outer ring 34, and the retaining frame 32 is arranged between the inner ring 31 and the outer ring 34, and the rolling body 33 can bear the radial load on the bearing and evenly distribute the load between the inner ring 31 and the outer ring 34 of the bearing. Taking the automobile wheel hub bearing as an example, when the vehicle is running, the weight of the wheel and various forces exerted on the wheel by the road surface will generate radial loads, and the rolling elements 33 are responsible for reasonably transmitting and distributing these forces between the wheel hub (corresponding to the outer ring 34 of the bearing) and the axle (corresponding to the inner ring 31 of the bearing) to ensure the driving stability of the vehicle. The number of rolling elements 33 is set to be several, and the several rolling elements 33 are distributed in a ring shape with equal spacing.

[0030] Furthermore, the mounting mechanism 4 includes a transverse plate 43, which is fixedly connected to both sides of the surface of the support 1. A mounting plate 44 is fixedly connected to the surface of the transverse plate 43. A fixing block 45 is fixedly connected to the side of the mounting plate 44 facing away from the transverse plate 43. The fixing block 45 is internally threaded with a fixing bolt 42. The fixing bolt 42 is horizontally arranged. The number of threaded fixing bolts 42 is two, and the two fixing bolts 42 are symmetrically arranged.

[0031] Furthermore, both sides of the surface of the support 1 are fixedly connected with connecting parts 41, and the connecting parts 41 pass through the fixing bolts 42. The connecting parts 41 are arranged on one side of the cross plate 43. By rotating the internal fixing bolts 42, the fixing bolts 42 and the external fixed object surface are tightly fixedly connected, thereby playing a stable supporting role for the support 1, ensuring that the bearing remains stable at all times during the subsequent operation process, and providing a solid basic guarantee for the normal operation of the equipment.

[0032] In actual operation, when this device is used, first of all, in mechanical equipment, the bearing is a key component, and its stable performance directly affects the operating efficiency and life of the equipment. In order to ensure that the bearing can work normally under various complex working conditions, it is very important to effectively seal and protect it; We adopt a unique way to install the seal 24, placing the seal 24 on both sides of the bearing. During the installation process, when the support member 21 is accurately inserted into the pre-opened limiting groove 26 in the connection block 27, the limiting rod 22 can be smoothly inserted into the circular hole groove opened in the limiting member 25. Then, by threading the locking nut along the surface of the limiting rod 22, the seal 24 can be easily and firmly installed. The ingenuity of this design is that when the seal 24 is damaged, it can be quickly disassembled and replaced by simply rotating the locking nut in the opposite direction, which greatly improves the convenience of maintenance and ensures that the seal 24 is always in normal use. The advantages of setting such a seal 24 that is easy to install and disassemble are significant. In equipment with harsh working environments such as construction machinery and mining machinery, a large amount of dust, soil, sand and other solid particles are everywhere. Once these impurities enter the bearing, they will directly increase the degree of wear of the bearing raceway, rolling element 33 and retainer 32. As the wear continues to increase, the accuracy of the bearing will be greatly reduced and the service life will be severely shortened. Our seal 24 device can effectively prevent the invasion of these impurities, just like putting a layer of solid protective armor on the bearing to ensure its normal operation. During the operation of the bearing, its working principle is based on the characteristics of rolling friction. When the shaft starts to rotate, the inner ring 31 that fits closely with the shaft also rotates synchronously, and the rolling body 33 continues to roll on the raceway between the inner ring 31 and the outer ring 34. Since the rolling friction coefficient is much smaller than the sliding friction coefficient, the shaft can rotate with a smaller friction torque when rotating. In this way, not only the energy loss is reduced, but also the mechanical efficiency is improved. Taking the wheel hub bearing of the car as an example, it is precisely because of the reasonable application of the rolling bearing that the wheel can remain smooth during the rotation process, which effectively reduces the fuel consumption of the car during driving and improves the energy utilization efficiency. In addition, during the installation of the entire equipment, when it is necessary to fix the support 1, the operation is also very simple. We can rotate the internal fixing bolt 42 to achieve a tight fixed connection between the fixing bolt 42 and the external fixed object surface, thereby providing a stable support for the support 1 and ensuring that the bearing remains stable during the subsequent operation process, providing a solid foundation for the normal operation of the equipment.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
