Abstract
Description
Technical Field
[0001] This invention belongs to the field of bearing ring production and design technology, and in particular relates to a composite bearing ring. Background Technology
[0002] Bearings operate smoothly and reliably with low noise, high load capacity, and high rotational accuracy, making them primarily used in high-speed, high-precision applications. Bearing rings are an integral part of the bearing. In current technology, common bearing rings are generally of a single, ring-shaped structure. Because of this integral ring structure, when a part of the bearing ring is damaged, the entire bearing ring must be disassembled and replaced, rendering the damaged ring unusable. This is especially problematic for large bearing ring parts, as it is not only cumbersome and time-consuming, impacting production efficiency, but also results in high operating costs. Therefore, it is necessary to improve the structure of existing bearing rings. Summary of the Invention
[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a combined bearing ring.
[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:
[0005] A composite bearing ring includes a bearing ring body and a detachable inner liner mounted on the inner wall of the bearing ring body. The bearing ring body includes an intermediate body and two separate parts fitted on its left and right sides. The inner diameter of the inner liner is smaller than the minimum inner diameter of the intermediate body and smaller than the minimum inner diameter of the separate parts. The intermediate body includes a base body and two cylindrical bodies on its two sides. The separate parts include a main body. The inner wall of the main body has an inner liner mounting part that mates with the inner liner. The inner wall of the main body has a mating part that mates with the cylindrical body. A limiting platform is formed at the junction of the inner wall of the mounting part and the inner wall of the mating part. The separate parts and the intermediate body are fixed together by radially arranged connectors. Each inner wall of the separate parts is provided with an inner liner between it and the intermediate body. The inner sides of the inner liner are limited by the side end face of the intermediate body and the limiting platform of the separate parts, respectively. Each outer wall of the cylindrical body has at least one axially arranged protrusion. The inner wall of the mating part of the separate parts has a groove that matches the protrusion.
[0006] Furthermore, the connector uses screws, with screw through holes on the main body corresponding to the mating part and threaded connection holes on the cylinder corresponding to the screw positions.
[0007] Furthermore, the screw holes on the split body are provided with a countersunk structure.
[0008] Furthermore, all the edges and corners of the intermediate body are chamfered.
[0009] Furthermore, all the edges and corners of the split parts are chamfered.
[0010] Furthermore, each of the outer circumferential surfaces of the cylinder has three protrusions.
[0011] Furthermore, all edges and corners of the lining are chamfered.
[0012] Furthermore, the base and the cylindrical bodies on both sides are integrally formed.
[0013] Compared with existing technologies, the present invention has the following advantages:
[0014] This invention features a rationally designed structure. By assembling a separate component on each of the left and right sides of the intermediate body and securing them to the intermediate body with connecting parts, the outer end face of the intermediate body's cylinder and the limiting platform of the separate component create a limiting space for the inner liner, holding the liner between the inner walls of the intermediate body and the separate components. This allows the intermediate body, the liner, and the two separate components on either side of the intermediate body to form the bearing ring body. The inner surface of the liner serves as the working surface in contact with the rotating shaft. When the liner wears, simply remove the connecting parts to separate the separate components from the intermediate body, and then replace the liner with a new one; the operation is simple and convenient. Except for the liner, which is a vulnerable structure, all other components of the bearing ring provided by this invention are reusable, thus effectively reducing operating costs.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.
[0026] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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 will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0028] The invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] A type of composite bearing ring, such as Figures 1 to 5 As shown, the bearing ring body includes a bearing ring body and a liner 3 that is detachably installed on the inner wall of the bearing ring body. The bearing ring body includes an intermediate body 1 and two separate bodies 2 fitted on its left and right sides. The inner diameter of the liner is smaller than the diameter at the minimum inner diameter of the intermediate body and smaller than the diameter at the minimum inner diameter of the separate bodies.
[0030] The intermediate body includes a base 4 and two cylindrical bodies 5 on both sides. The secondary body includes a main body, the inner wall of which has an inner lining mounting part 6 that mates with the inner lining, and a mating part 7 that mates with the cylindrical bodies. A limiting platform 8 is formed at the junction of the inner wall of the mounting part and the inner wall of the mating part. Preferably, the base and the cylindrical bodies on both sides are integrally formed.
[0031] The split body and the intermediate body are fixed together by radially arranged connectors 14. Each split body has an inner liner between its inner wall and the intermediate body, and the liner is limited on both sides by the side end face of the intermediate body and the limiting platform of the split body, respectively. Each cylinder's outer wall has at least one axially arranged protrusion 9, and the inner wall of the mating part of the split body has a groove 10 that matches the protrusion. For example, such as... Figure 6 As shown, each of the outer circumferential surfaces of the cylinder has three protrusions.
[0032] When assembling the bearing rings, aligning the protrusion with the slot ensures proper fit between the intermediate body and the split body. The fit between the slot of the split body and the protrusion on the intermediate body effectively improves the structural stability between the intermediate body and the split body, resulting in good circumferential load-bearing capacity.
[0033] All edges of the intermediate body are chamfered. All edges of the split body are chamfered. All edges of the inner lining are chamfered. In an optional embodiment, the connector is a screw, with a screw through hole 11 on the main body corresponding to the mating part, and a threaded connection hole 12 on the cylinder corresponding to the screw position. To avoid interference between the connector and other structures, a countersunk structure 13 is provided on the screw through hole on the split body.
[0034] To improve the structural stability between the split body and the liner, in an optional embodiment, such as Figures 7 to 9 As shown, limiting grooves 15 are provided at both ends of the outer wall of the inner lining, and limiting posts 16 that cooperate with the limiting grooves are provided on the inner wall of the split inner lining installation part.
[0035] When assembling the bearing rings, aligning the limiting post with the limiting groove ensures proper fit between the inner bushing and the split body. The fit between the limiting post of the split body and the limiting groove of the inner bushing effectively improves the structural stability between the split body and the inner bushing, resulting in good circumferential load-bearing capacity.
[0036] This invention features a rationally designed structure. By assembling a separate component on each of the left and right sides of the intermediate body and fixing them to the intermediate body with connecting parts, the outer end face of the intermediate body's cylinder and the limiting platform of the separate component create a limiting space for the inner liner, holding the liner between the inner wall of the intermediate body and the inner wall of the separate component. This allows the intermediate body, the liner, and the two separate components on either side of the intermediate body to form the bearing ring body. The inner surface of the liner serves as the working surface in contact with the rotating shaft. When the liner wears, simply remove the connecting parts to separate the separate component from the intermediate body, and then replace it with a new liner. The operation is simple and convenient. It should be noted that, except for the liner, which is a vulnerable structure, all other components of the bearing ring provided by this invention are reusable, thus effectively reducing usage costs, especially for large bearing rings, where the cost reduction effect is significant.
[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
