Description

Technical Field

[0001] This utility model relates to the field of bearing product technology, and more specifically, to a suspension transmission bearing. Background Technology

[0002] Bearings support rotating mechanical bodies, reduce the coefficient of friction during their movement, and enable them to rotate with high precision. As a transmission component, bearings are widely used in engineering machinery, aerospace machinery, and chemical machinery. In aerospace applications, bearings are also required in specific suspension transmission scenarios. Bearings used in these scenarios often need to be installed in specific bearing housings. In practice, it has been found that bearing transmission components have many parts, inconvenient assembly, and large overall weight, failing to meet lightweight requirements. Bearings need to be inserted into the shaft end for use. Over long-term use, the shaft end will wear, and the transmission stability between the shaft end and the bearing will deteriorate. These problems urgently require the design of specially made bearings to solve, hence this project. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a suspension transmission bearing. This utility model is designed with a coupling with a flange and a cam, which can be directly bolted to shaft components, effectively solving the problem of poor transmission stability during bearing use. The outer ring of the bearing is designed in the shape of a seat, so it can be directly connected and installed without the need for matching bearing seat parts. The outer ring and inner ring of the bearing are reasonably arranged and installed to meet the requirements of suspension transmission.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A suspension drive bearing includes an outer bearing ring and a coupling. An inner bearing ring is fixedly installed on the outer wall of the coupling. The coupling is inserted into the inner bearing ring of the outer bearing ring. A roller groove is formed between the inner and outer bearing rings. A plurality of rollers are installed in the roller groove. A flange support is formed by a protrusion on the outer wall of the outer bearing ring. A plurality of bolt holes are provided on the flange support.

[0006] Furthermore, the coupling adopts a tubular shape, with a through hole in the center. The outer diameter of the coupling matches the inner ring of the bearing. One end of the outer wall of the coupling has a flange protrusion, and several threaded holes are evenly distributed on the side wall of the flange. The inner ring of the bearing is installed from the non-flange flange end of the coupling.

[0007] Furthermore, the coupling has a thin-walled section at the flange end, which can be bent and folded outward to form a sidewall. An inner ring groove is formed between the sidewall and the flange, and the bearing inner ring is fixed in the inner ring groove.

[0008] Furthermore, the thickness of the thin-walled section is less than 1 mm.

[0009] Furthermore, a first groove is formed on the inner side of the outer ring of the bearing, and the inner ring of the bearing includes a first half inner ring and a second half inner ring. The first half inner ring and the second half inner ring have the same structure. The first half inner ring and the second half inner ring are spliced ​​together in a symmetrical arrangement. After the first half inner ring and the second half inner ring are assembled, a second groove is formed. The first groove and the second groove can be combined to form a square roller groove.

[0010] Furthermore, both the bottom of the first and second trenches are provided with shallow grooves.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4 The suspended transmission bearing shown includes an outer bearing ring 1 and a coupling 2. An inner bearing ring 3 is fixedly mounted on the outer wall of the coupling 2. The coupling 2 is inserted into the inner side of the outer bearing ring 1 with the inner bearing ring 3 partially inserted. A roller groove 4 is formed between the inner bearing ring 3 and the outer bearing ring 1. Several rollers 5 are installed within the roller groove 4. A flange support 13 is formed by a protrusion on the outer wall of the outer bearing ring 1. Several bolt holes 131 are provided on the flange support 13. This utility model is specially designed with the outer bearing ring 1 and coupling 2 according to usage requirements. In use, the coupling 2... To connect with shaft-type parts, the outer ring 1 of the bearing is designed in the shape of a seat to achieve direct fixed installation of the outer ring 1. Bolts can be installed in the bolt holes 131 of the flange support 13, so that this utility model can be directly suspended and installed in the use position without the need for additional bearing seat parts for installation. The above design is to meet the requirements of bearing integration and lightweight. The bearing can be directly installed. Due to the reduction of parts, the overall weight of the bearing transmission part will be significantly reduced. Integration also reduces the difficulty of bearing installation and is suitable for quick installation in small spaces.

[0021] like Figure 2 As shown, the coupling 2 has a tubular shape and a through hole 21 in the center. The through hole 21 is used to connect the shaft head of the shaft part. The outer diameter of the coupling 2 matches the inner ring 3 of the bearing. The inner ring 3 of the bearing can be fitted onto the outside of the coupling 2. One end of the outer wall of the coupling 2 has a flange cam 22 protruding. Several threaded holes 221 are evenly distributed on the side wall of the flange cam 22. The design of the flange cam 22 allows the coupling 2 to be bolted to the shaft part, which can greatly improve the stability of the transmission. Even if the shaft head is worn and loose, the transmission can still be normal. The flange cam 22 end is significantly higher than the outer wall of the coupling 2. Therefore, the inner ring 3 of the bearing is installed from the non-flange cam 22 end of the coupling 2.

[0022] like Figure 3 As shown, the non-flange cam 22 end of the coupling 2 is provided with a thin-walled section 23. The bearing inner ring 3 is installed from the thin-walled section 23. This is the initial form of the coupling 2. After the bearing inner ring 3 is installed, a riveting operation is applied to the thin-walled section 23, so that the thin-walled section 23 is bent and folded outward to form a side wall 24. The side wall 24 is also higher than the outer wall of the coupling 2. Therefore, an inner ring groove 25 is formed between the side wall 24 and the flange cam 22. After the side wall 24 is formed, the bearing inner ring 3 is fixed in the inner ring groove 25 to achieve the installation purpose. In this utility model, the design thickness of the thin-walled section 23 is set to be less than 1mm. The thin-walled section 23 with a thickness of less than 1mm can facilitate the riveting operation.

[0023] like Figure 2 As shown, a first groove 11 is formed on the inner side of the outer ring 1 of the bearing, such as... Figure 4 As shown, the bearing inner ring 3 includes a first half-inner ring 31 and a second half-inner ring 32. The first half-inner ring 31 and the second half-inner ring 32 have the same structure and are symmetrically arranged and spliced ​​together. After the first half-inner ring 31 and the second half-inner ring 32 are assembled, a second groove 33 is formed. The first groove 11 and the second groove 33 can be combined to form a square roller groove 4. When the bearing is in use, the roller 5 moves in the square roller groove 4. After the lightweight design of the bearing, there is an assembly problem between the coupling 2 and the bearing inner ring 3. The above design of this utility model is to address this issue. To solve the assembly problem of coupling 2 and bearing inner ring 3, this utility model specifically divides the bearing inner ring 3 into two half inner rings. During assembly, the first half inner ring 31 is first installed onto coupling 2, then coupling 2 is inserted into bearing outer ring 1. After filling in the rollers 5, the second half inner ring 32 is installed on coupling 2 to form an inner and outer ring and roller structure. Finally, a thin-walled section 23 is machined to fix the bearing inner ring 3. In this way, the entire bearing component can be assembled in an orderly manner. Its structural layout is reasonable, and the installation sequence is interlocked, which can effectively solve the bearing assembly problem.

[0024] like Figure 2 and Figure 4 As shown, the bottom of the first groove 11 and the second groove 33 are both provided with shallow grooves 12. The design of the shallow grooves 12 can reduce the machining difficulties of the first groove 11 and the second groove 33 (facilitating tool entry and exit), and increase the grease storage space to ensure sufficient lubrication of the roller 5 and extend the service life of the bearing product.

[0025] This utility model not only meets the requirements of suspension transmission, but also has the advantages of high integration, light weight, and convenient installation. The bearing product of this utility model has broad application prospects.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
