Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing wear technology, and in particular to an anti-wear device for bearings. Background Technology
[0002] In the field of mechanical transmission, bearings, as core components for achieving rotational motion, directly affect the service life and operational stability of equipment due to friction and wear between the bearing and its mounting carrier. Currently, anti-wear measures for bearings mainly focus on the following two types of solutions, but both have significant technical limitations:
[0003] The unavoidable vibrations during mechanical operation lead to impact contact between the bearing column and wear-resistant components. Existing devices mostly use rigid contact structures, lacking effective buffering mechanisms. The vibration impact force is directly transmitted to the bearing and the contact components, easily causing deformation and damage to the contact components, and exacerbating vibration wear on the bearing, especially in high-frequency vibration scenarios (such as motors and pumps). Some improved devices incorporate single or a few contact components between the bearing column and the mounting plate, but these present two major problems: First, the contact components are mostly rigid fixed structures, unable to adaptively adjust to slight radial offsets or dimensional fluctuations in the bearing column, easily leading to "localized excessive compression" or "contact gaps," resulting in uneven stress on the bearing column and causing localized uneven wear. Second, during bearing operation, friction generates metal debris. Existing devices lack dedicated debris collection structures, allowing debris to accumulate in the contact gap between the bearing column and the mounting hole, forming "abrasive particles." These debris not only exacerbate scratches and wear on the bearing column surface, but also clog the bearing lubrication channels, leading to lubrication failure and further worsening the wear problem. In addition, existing devices mostly use bolted or welded connections, which require special tools for disassembly and assembly, making the operation cumbersome and making it difficult to quickly inspect and replace contact parts during maintenance, thus reducing the efficiency of equipment operation and maintenance.
[0004] In summary, existing bearing wear prevention solutions have significant shortcomings in terms of adaptability, stress balance, debris handling, ease of disassembly and assembly, and vibration damping. They are insufficient to meet the requirements of mechanical equipment for bearings to provide "long-term wear prevention, flexible adaptation, and convenient maintenance." There is an urgent need for a new type of wear prevention device that can solve the above-mentioned multi-dimensional problems.

However, this does not mean that this utility model does not have the features of these prior art.

Detailed Implementation
[0020] The following is a detailed explanation with reference to the accompanying drawings.
[0021] Example 1
[0022] This utility model provides a wear-resistant device for bearings, such as... Figure 1 and Figure 2As shown, the system includes a first main board 100 and a second main board 200. The first main board 100 and the second main board 200 are connected by a snap-fit mechanism. The first main board 100 and the second main board 200 are mirror images of each other, and a first post hole 101 and a second post hole 201 for accommodating a bearing post are provided at the intermediate connection between the first main board 100 and the second main board 200. At least one anti-wear component 300 is provided on both the first main board 100 and the second main board 200. The anti-wear component 300 includes a plurality of abutment members 301 for sliding contact with the bearing post, a plurality of support columns 302 corresponding to the plurality of abutment members 301 and passing through the axis of the abutment members 301, a first support plate 303 connected to the plurality of support columns 302, and a second support plate 304 connected to the first support plate 303. This invention enables quick assembly and disassembly of the device through the snap-fit connection between the first main board 100 and the second main board 200, reducing the difficulty of assembly and maintenance. The mirrored arrangement of the two main boards, along with the first post hole 101 and the second post hole 201 in the middle, can accurately position and accommodate the bearing post, ensuring the coaxiality of the bearing post and the device, and avoiding excessive local wear caused by assembly deviation. The anti-wear component 300 can directly contact the bearing post to form protection, blocking the direct friction between the bearing post and the main board, providing basic anti-wear protection for the bearing post. Overall, it achieves the dual functions of convenient assembly and initial protection.
[0023] According to a preferred embodiment, a plurality of abutment members 301 are configured in the form of ball bearings, and a plurality of corresponding support columns 302 are rotatably connected to the abutment members 301 by passing through the center of the abutment members 301. The ball bearing abutment members 301 convert the sliding friction between the bearing post and the abutment member 301 into rolling friction, significantly reducing the coefficient of friction and reducing wear. The support columns 302 are rotatably connected to the abutment members 301 by passing through the center of the abutment members 301, ensuring that the ball bearings rotate smoothly around the support columns 302, avoiding jamming, and ensuring stable conversion of the friction mode. This not only improves the smoothness of the bearing post operation but also significantly extends the service life of the abutment members 301 and the bearing post.
[0024] According to a preferred embodiment, a plurality of support columns 302 are fixedly connected to a first support plate 303. The first support plate 303 is fixedly connected to the end of a second support plate 304 away from the first main plate 100 or the second main plate 200. It should be noted that the abutment members 301 and the first support plate 303 are made of flexible material, enabling them to abut against bearing columns of different radii. When the radius of the bearing column is too large, since the curvature of the plurality of abutment members 301 is fixed, the abutment members 301 on both sides will contact the bearing column first, thus undergoing slight deformation due to their own flexibility and the flexibility of the first support plate 303, thereby applying a clamping force to the bearing column. Furthermore, due to the rigidity of the support columns 302, the force applied by the bearing column to the abutment members 301 and the first support plate 303 is converted into a force towards the horizontal sides of the first support plate 303, thereby increasing the clamping force on the bearing column. The structure of the support column 302 being fixedly connected to the first support plate 303 and the first support plate 303 being connected to the second support plate 304 provides stable support for the wear-resistant component 300. The flexible material of the abutment 301 and the first support plate 303 enables them to deform, allowing them to adapt to bearing columns of different radii and improving the versatility of the device. When the bearing column radius is too large, the abutment 301 on both sides first contacts and generates clamping force through deformation, tightly fitting the surface of the bearing column and avoiding wobbling and wear caused by gaps. The rigid support column 302 converts the force applied by the bearing column into the force on both sides of the first support plate 303, enhancing the clamping force and providing support for the flexible structure, preventing excessive deformation failure and achieving a balance between "flexible adaptation" and "rigid clamping".
[0025] According to a preferred embodiment, the first main board 100 is provided with a first groove 102 corresponding to at least one second support plate 304. One end of the second support plate 304 extends into the first groove 102 to move radially along the first post hole 101 within the first groove 102. The first groove 102 on the first main board 100 provides a radial movement path for the second support plate 304, allowing the anti-wear component 300 to adaptively adjust to changes in the bearing post radius or slight positional shifts during operation, ensuring that the abutment 301 always effectively contacts the bearing post, avoiding problems of "inadequate contact" or "excessive compression"; the radial movement characteristic allows the device to maintain a close fit even when the bearing post experiences slight shaking (radius change), improving the continuity and reliability of protection.
[0026] According to a preferred embodiment, the second main board 200 is provided with a second slide groove 202 corresponding to at least one second support plate 304. One end of the second support plate 304 extends into the second slide groove 202 to move radially along the second column hole 201 within the second slide groove 202. The second slide groove 202 on the second main board 200 forms a symmetrical fit with the first slide groove 102 on the first main board 100, so that the anti-wear components 300 on both the first main board 100 and the second main board 200 have radial adjustment capabilities, ensuring uniform force on the bearing column (or both sides), avoiding imbalance of force on the bearing column caused by unilateral adjustment, and reducing local uneven wear; the symmetrical slide groove structure can also improve the overall structural symmetry of the device, ensure the coaxiality of the bearing column operation, reduce vibration wear, and enhance the uniformity of the anti-wear effect.
[0027] According to a preferred embodiment, a first spring 103 is provided between the second support plate 304 and the first slide groove 102, along the radial direction of the first column hole 101, and a second spring 203 is provided between the second support plate 304 and the second slide groove 202, along the radial direction of the second column hole 201. The first spring 103 between the second support plate 304 and the first slide groove 102, and the second spring 203 between the second support plate 304 and the second slide groove 202, can provide elastic preload, so that the second support plate 304 drives the anti-wear component 300 to always have a tendency to resist in the direction of the bearing column, ensuring that the abutment 301 and the bearing column are stably fitted, avoiding frictional wear caused by gaps; when the radius of the bearing column changes or slight vibration occurs, the spring automatically compensates for the displacement by extension and contraction, buffers external impact, reduces the impact of vibration on contact stability, and avoids excessive friction caused by rigid contact, realizing the dual functions of "elastic adaptation" and "buffering protection", improving the vibration resistance and protective stability of the device.
[0028] According to a preferred embodiment, the second support plate 304 is inclined at the midpoint between the first support plate 303 and the first slide groove 102 or the second slide groove 202. The end of the second support plate 304 furthest from the first support plate 303 engages with the first slide groove 102 or the second slide groove 202 in an "I" shape. The inclined second support plate 304 optimizes the force transmission direction, making the clamping force of the first support plate 303 and the abutment 301 on the bearing column more closely match the force requirements, improving clamping rationality. The "I"-shaped engagement structure at the end of the second support plate 304 furthest from the first support plate 303 restricts its movement direction within the first slide groove 102 or the second slide groove 202, preventing component detachment, ensuring structural stability, and avoiding protection failure. Simultaneously, the "I"-shaped structure reduces the contact gap between the second support plate 304 and the slide groove, reducing lateral sway and ensuring that the second support plate 304 moves precisely only radially, improving adjustment accuracy and ensuring the contact stability of the anti-wear component 300.
[0029] According to a preferred embodiment, at least three anti-wear components 300 are disposed on the first main board 100 or the second main board 200. At least six anti-wear components 300 are disposed on the first main board 100 and the second main board 200, arranged rotationally symmetrically with respect to the centers of the first and second bore holes 101 and 201. The at least three anti-wear components 300 disposed on the first main board 100 or the second main board 200 can form multi-point contact in the circumferential direction of the bearing column, avoiding force concentration caused by single / two-point contact and reducing localized excessive wear. The at least six anti-wear components 300 disposed on the first main board 100 and the second main board 200, arranged rotationally symmetrically with respect to the centers of the first and second bore holes 101 and 201, ensure uniform force distribution in the circumferential direction of the bearing column, consistent protection in each direction, elimination of weak areas, and prevention of localized uneven wear. The symmetrical distribution also improves the positioning accuracy of the device for the bearing column, avoids operational deviation, comprehensively covers circumferential anti-wear requirements, and enhances the comprehensiveness and reliability of protection.
[0030] According to a preferred embodiment, when at least six anti-wear components 300 are provided, the rotation angle between two adjacent anti-wear components 300 is set to 60°. The 60° rotation angle between the six adjacent anti-wear components 300 is a uniformly divided angle of the 360° circumference, ensuring that the components are completely equidistantly distributed circumferentially on the bearing post. This ensures that the magnitude and spacing of the contact force between each anti-wear component 300 and the bearing post are completely consistent, completely eliminating uneven circumferential force and preventing excessive local wear in any direction. The equidistant distribution structure is suitable for high-precision bearing operation scenarios, meets high wear control requirements, further improves the protection accuracy and balance of the device, and ensures long-term stable operation of the bearing post.
[0031] According to a preferred embodiment, magnetic grooves 400 for collecting debris are provided on the circumferential edges of the first main board 100 near the first post hole 101 and the second main board 200 near the second post hole 201. The magnetic grooves 400 on the first main board 100 and the second main board 200 near the second post hole 201 can magnetically attract metal debris generated during bearing operation, preventing debris accumulation in the contact area between the first / second post hole 101 and the bearing post, thus reducing wear caused by debris at the source. Simultaneously, the magnetic grooves 400 collect debris, facilitating subsequent cleaning and maintenance without disassembling the device, reducing maintenance costs. Furthermore, reducing debris residue can prevent scratches on the bearing post surface, extending the service life of the bearing post and the device, and improving maintenance convenience and long-term protection.
