A type of combined bearing ring

Abstract

This invention provides a combined bearing ring, comprising a base body, within which a working body is installed. The working body includes a cylindrical bushing portion with a flanged structure at one end, on which several connecting parts are provided. At least one end face of the base body has a mounting platform, to which the connecting parts are connected. The flanged structure is recessed into the mounting platform, and the outer edge of the connecting parts does not protrude from the end face of the base body. Simultaneously, several positioning protrusions are provided on the outer wall of the bushing portion, and corresponding grooves are provided on the inner wall of the base body. This invention features a reasonable structural design, achieving the function of a bearing ring by combining the working body and the base body. The base body serves as the structural foundation, while the bushing portion is the component that directly engages with the shaft. Even if wear occurs after long-term use, the base body can be reused by replacing the working body separately. This simple operation saves on operating costs and is particularly suitable for large bearing ring products.

Description

Technical Field

[0001] This invention belongs to the technical field of bearing ring products, and in particular relates to a combined bearing ring. Background Technology

[0002] As an important component of bearings, bearing races are generally in the form of a single ring. Because of this integral ring structure, when a part of the bearing race is damaged, the entire bearing race must be disassembled and replaced, and the damaged bearing race is scrapped. This is especially true for large bearing race parts, which is not only cumbersome and time-consuming, affecting production efficiency, but also leads to high operating costs. Therefore, it is necessary to optimize and improve the existing bearing races. 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 base, in which a working body is installed. The working body includes a cylindrical bushing portion, one end of which has a flange structure, and a plurality of connecting parts are provided on the flange structure. At least one end face of the base has a mounting platform, and the connecting parts are connected to the mounting platform. The flange structure is recessed into the mounting platform, and the outer edge of the connecting parts does not protrude from the end face of the base. Meanwhile, a plurality of positioning protrusions are provided on the outer wall of the bushing portion, and the inner wall of the base has grooves corresponding to each positioning protrusion.

[0006] Furthermore, each of the connecting components is evenly distributed along the circumferential direction of the flange structure.

[0007] Furthermore, the connector is provided with 3-5 pieces.

[0008] Furthermore, the connector is made of screws.

[0009] Furthermore, the mounting platform is provided with fixing holes that correspond one-to-one with the connectors.

[0010] Furthermore, the fixing hole is a threaded hole.

[0011] Furthermore, the positioning protrusion has the same length as the bushing portion in the axial direction.

[0012] Furthermore, the positioning protrusion extends 1-2.5mm beyond the outer wall of the bushing portion.

[0013] Furthermore, the outer wall of the bushing is provided with 2-5 positioning protrusions at equal intervals along the circumferential direction.

[0014] Compared with existing technologies, the present invention has the following advantages:

[0015] This invention features a rational structural design. By combining the working body and the base body into one unit, the bearing ring function is achieved. The base body serves as the structural foundation, while the bushing part is the component that directly mates with the shaft. Even if wear occurs after long-term use, the base body can be reused by replacing the working body separately. The operation is simple and saves on usage costs, making it particularly suitable for large bearing ring products. Attached Figure Description

[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 6 As shown, the system includes a base 1, within which a working body 2 is installed. The working body includes a cylindrical bushing 3, one end of which has a flanged structure 4. The flanged structure has several connecting holes 5, each with a connector 6 installed. At least one end of the base has a mounting platform 7. The flanged structure is connected to the mounting platform via the connectors, thus fixing the working body to the base. To avoid interference between the working body and external structures, the flanged structure is recessed into the mounting platform, and the outer edge of the connector does not protrude from the end face of the base. Preferably, the connecting holes have a countersunk structure.

[0030] Meanwhile, to reduce the shear force of the connectors and ensure the stability of the combined structure of the base and the connectors, several positioning protrusions 8 are provided on the outer wall of the bushing, and slots 9 are provided on the inner wall of the base corresponding to each positioning protrusion. During assembly, simply align the positioning protrusions of the working body with the slots of the base, then slowly insert the bushing into the inner cavity of the base until the flange structure abuts against the mounting platform, and then tighten the connectors to fix the flange structure to the mounting platform, thereby ensuring that the working body and the base are securely fixed.

[0031] Each of the aforementioned connectors is evenly distributed along the circumference of the flange structure. There are 3-5 connectors. Each connector uses a screw. The mounting platform has corresponding fixing holes 10 for each connector. These fixing holes are threaded holes.

[0032] The positioning protrusions are the same length as the bushing in the axial direction. The positioning protrusions extend 1-2.5mm beyond the outer wall of the bushing. Two to five positioning protrusions are evenly spaced along the circumference of the outer wall of the bushing. The working body, through the positioning protrusions and the grooves in the base, forms a mating relationship, effectively bearing the torque of relative rotation between the base and the working body, greatly reducing the shear force on the connecting parts. Therefore, this combined bearing ring can operate stably for a long time, with reliable performance and a guaranteed service life.

[0033] This invention features a rational structural design. By combining the working body and the base body into one unit, the bearing ring function is achieved. The base body serves as the structural foundation, while the bushing part is the component that directly mates with the shaft. Even if wear occurs after long-term use, the base body can be reused by replacing the working body separately. The operation is simple and saves on usage costs, making it particularly suitable for large bearing ring products.

[0034] 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.
