Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically a split-half bearing. Background Technology

[0002] In existing technologies, traditional bearing structures often employ an integral design, such as the split self-aligning roller bearing cage and its self-aligning roller bearing disclosed in Chinese Patent (CN201820963263.6). This patent solves the radial clearance and deformation problems caused by traditional connecting plate structures through Z-shaped splicing surfaces and screw connections. However, its integral design still has the following limitations: Material waste: In many applications, especially in large, low-speed machinery, the outer ring does not need to withstand the same stress as the rolling elements, leading to excessive material use and waste. Inconvenient replacement: During use, once the rolling elements or cage of a traditional bearing wears out, the entire bearing usually needs to be replaced, making partial repair or replacement impossible, resulting in resource waste and increased maintenance costs. Limited service life: During use, integral bearings are prone to fatigue failure due to wear between the rolling elements and the cage, as well as radial clearance caused by cage deformation, affecting the bearing's service life.

[0003] To address the aforementioned problems, no effective solution has been proposed in the existing technology. Therefore, this utility model aims to optimize the bearing structure through a split-half design, thereby solving the problems of material waste, inconvenient replacement, and limited service life existing in the prior art. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a split-bearing, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a split-half bearing, comprising an inner ring, two outer half rings, and multiple rolling elements. The two outer half rings are assembled by snap-fitting to form the outer ring of the bearing. Each rolling element is rotatably mounted on the inner sidewall of the two outer half rings. The inner ring is inserted into the interior of the two outer half rings, and the outer sidewall of the inner ring abuts against the outer sidewall of each rolling element. The inner ring is rotatably connected to the outer ring of the bearing through the rolling elements.

[0008] Optionally, the semi-outer ring includes an outer ring and two flower discs. The outer ring is semi-circular in shape, and the flower discs are semi-circular in shape. The outer periphery of the flower discs is welded to the inner wall of the outer ring, and the two flower discs are arranged in parallel. Multiple grooves arranged circumferentially are formed on the inner periphery of the flower discs. The two ends of the rolling element are rotatably installed in the grooves adjacent to the two flower discs, and the rolling element is cylindrical.

[0009] Optionally, the rolling element includes a shaft and a plurality of small bearings, each of which is mounted on the outer side wall of the middle part of the shaft and arranged sequentially along the axial direction; the two ends of the shaft are respectively engaged in the slots of two adjacent flower discs.

[0010] Optionally, the outer ring of the semi-circle further includes two fixing plates, the fixing plates being semi-circular in shape, and the outer periphery of the fixing plates being welded to the inner wall of the outer ring.

[0011] Optionally, the middle part of the outer side wall of the inner ring is a recessed portion, and the outer side wall of each of the small bearings abuts against the recessed portion of the inner ring.

[0012] (III) Beneficial Effects

[0013] This utility model provides a split-half bearing, which has the following beneficial effects:

[0014] 1. This type of split-ring bearing features a split outer ring design, where the outer ring can be made of ordinary steel, while only the inner ring uses high-quality bearing steel. This material optimization significantly reduces the amount of bearing steel used, lowering manufacturing costs. Simultaneously, the split-ring design makes bearing installation and maintenance more convenient, further reducing maintenance costs.

[0015] 2. This type of split-bearing features a modular design for the rolling elements. When individual rolling elements wear, only the worn element needs to be replaced; when some smaller bearings wear, only the corresponding module needs to be replaced, without replacing the entire bearing. Rolling element replacement is more convenient, allowing for targeted replacement of worn elements, reducing equipment costs and extending the overall bearing life. The recessed design of the inner ring, which fits with the smaller bearings, ensures more even force distribution on the rolling elements, reducing wear and thus extending the bearing's lifespan.

[0016] 3. This type of split-half bearing, through its split-half design, makes disassembly and assembly of the bearing more convenient. During maintenance, the outer ring of the half can be easily removed by simply loosening the locking mechanism for internal inspection and repair, greatly reducing maintenance time and costs.

[0017] 4. In practical applications, when the rolling elements on the lower half of the outer ring wear excessively due to gravity, the relatively intact rolling elements on the upper half of the outer ring can be removed and replaced on the lower half, thus reversing their positions and significantly extending the bearing's service life. The rolling elements can be replaced and reused multiple times, overcoming the severe losses associated with single-use bearings in older models. This achieves energy conservation, efficiency improvement, and extended bearing lifespan, optimizing the bearing's structure and usage. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0028] Please see Figures 1 to 6 This utility model provides a technical solution: a split-half bearing, comprising an inner ring 3, two outer rings 1 of the two halves, and multiple rolling elements 4, wherein the two outer rings 1 of the halves are assembled by interlocking. In actual implementation, the two outer rings 1 of the halves can be detached and installed, and when they are interlocked together, they form a complete circular bearing outer ring.

[0029] Each rolling element 4 is rotatably mounted on the inner sidewall of the two half-outer rings 1. The inner ring 3 is inserted inside the two half-outer rings 1, and the outer sidewall of the inner ring 3 abuts against the outer sidewall of each rolling element 4. The inner ring 3 is rotatably connected to the outer ring of the bearing through each rolling element 4.

[0030] Each rolling element 4 is rotatably mounted on the outer ring of the bearing, and the inner ring 3 can rotate on the outer ring of the bearing through each rolling element 4.

[0031] Specifically, the outer ring 1 of the semi-circle includes an outer ring 101 and two flower discs 102. The outer ring 101 is semi-circular in shape, and the flower discs 102 are also semi-circular in shape. The outer periphery of the flower discs 102 is welded to the inner wall of the outer ring 101, and the two flower discs 102 are arranged in parallel. Multiple circumferentially arranged slots 1021 are formed on the inner periphery of the flower discs 102. The two ends of the rolling element 4 are rotatably mounted in the adjacent slots 1021 of the two flower discs 102, and the rolling element 4 is cylindrical. The outer ring 1 of the semi-circle also includes two fixing plates 103. The fixing plates 103 are semi-circular in shape, and the outer periphery of the fixing plates 103 is welded to the inner wall of the outer ring 101.

[0032] The outer ring 101 is semi-annular in shape, serving as the outer layer of the split bearing and bearing external loads. The faceplate 102 is also semi-annular and welded to the inner wall of the outer ring 101. Multiple circumferentially arranged grooves 1021 are formed on the inner periphery of the faceplate 102 for mounting the rolling elements 4. The design of the faceplate 102 makes the mounting of the rolling elements 4 more stable and enhances the overall strength of the bearing. The fixing plate 103 is also semi-annular and welded to the inner wall of the outer ring 101. It is used to fix the gasket and sealing plate, enhancing the bearing's sealing performance and preventing lubricant leakage and impurity ingress. The two halves of the outer ring 1 are assembled together to form the complete bearing outer ring. During use, the outer ring 101 bears external loads and transmits the load to the rolling elements 4 through the faceplate 102. The fixing plate 103 ensures the stability of the sealing structure and extends the bearing's service life.

[0033] More specifically, the rolling element 4 includes a shaft 401 and a plurality of small bearings 402. Each small bearing 402 is fitted onto the middle outer side wall of the shaft 401, and the small bearings 402 are arranged sequentially along the axial direction. The two ends of the shaft 401 are respectively engaged in the adjacent slots 1021 of the two flower discs 102. The middle part of the outer side wall of the inner ring 3 is a recessed portion 302, and the two ends of the outer side wall of the inner ring 3 are raised platform portions 301. The outer side wall of each small bearing 402 abuts against the recessed portion 302 of the inner ring 3.

[0034] The shaft 401 serves as a support structure, ensuring the stable installation of the rolling element 4. The small bearing 402 is made of high-quality bearing steel, ensuring the wear resistance and load-bearing capacity of the rolling element 4. The rolling element 4 is installed in the slot 1021 of the disc 102 via the shaft 401. The small bearing 402 rolls in the recess 302 of the inner ring 3, achieving relative rotation between the inner ring 3 and the outer ring 1. The modular design makes replacing the rolling element 4 more convenient. When some of the small bearings 402 wear, only the corresponding module needs to be replaced, without replacing the entire rolling element 4. When the entire rolling element 4 wears, the entire rolling element 4 can be replaced. The locking structure between the rolling element 4 and the disc 102 facilitates disassembly and replacement, making maintenance easy. The raised platform 301 on the outer wall of the inner ring 3 limits the small bearing 402, preventing the inner ring 3 from slipping during rotation. The recessed portion 302 on the outer side wall of the inner ring 3 abuts against the outer side wall of the small bearing 402, ensuring that the rolling element 4 is subjected to uniform force during rotation and reducing wear. The raised platform portion 301 of the inner ring 3 blocks each small bearing 402, and each small bearing 402 rolls along the recessed portion 302 during the rotation of the inner ring 3. At the same time, each small bearing 402 also limits and blocks the inner ring 3, preventing the inner ring 3 from slipping. That is, the rolling element 4 limits the inner ring 3 and prevents the inner ring 3 from deviating.

[0035] During use, the installation process is as follows: First, the rolling element 4 is installed in the slot 1021 of the disc 102 via the shaft 401. The inner ring 3 is placed inside the lower half of the outer ring 1, with the recess 302 of the inner ring 3 abutting against the rolling element 4. The other half of the outer ring 1 is then snapped onto the upper part of the lower half of the outer ring 1. The two half-rings are then assembled into a complete bearing outer ring using the snap-fit ​​installation. The fixing plate 103 is used to fix the sealing gasket and sealing plate, ensuring the bearing's sealing performance.

[0036] Operation: During bearing operation, the inner ring 3 rotates relative to the outer ring via the rolling elements 4. The small bearing 402 of the rolling elements 4 rolls within the recess 302 of the inner ring 3. The fit between the recess 302 and the small bearing 402 ensures even force distribution on the rolling elements 4, reducing wear. The raised platform 301 limits the movement of the small bearing 402, ensuring the stability of the inner ring 3.

[0037] Maintenance process: When the rolling element 4 or inner ring 3 is worn, simply loosen the snap fastener, remove one half of the outer ring 1, and replace the corresponding rolling element 4. This modular design greatly reduces maintenance time and cost.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
