Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical roller bearings, in particular to a cylindrical roller bearing assembly. Background Art

[0002] Cylindrical roller bearings are rolling bearings primarily designed to withstand radial loads. Their primary structure consists of an inner ring, outer ring, rollers, and a cage. Cylindrical roller bearings have cylindrical rollers, which provide a large contact area and can withstand heavy loads. They are widely used in many industrial applications, particularly those involving high loads and high speeds.

[0003] Multi-row cylindrical roller bearings are available in various sizes on the market to meet different application requirements. Multi-row cylindrical roller bearings contain multiple roller rows within the same bearing to increase load capacity and rigidity. Common types include double-row cylindrical roller bearings (NN, NNU, N, NF series), four-row cylindrical roller bearings (QJ, QJN series), and multi-row cylindrical roller bearings (e.g., six-row and eight-row).

[0004] Currently, most multi-row cylindrical roller bearings are monolithic and come in a variety of sizes. This can complicate the manufacturing process and increase inventory costs for manufacturers. Furthermore, custom production may be required for specialized needs, increasing costs. Furthermore, for users, problems with a single row in a monolithic multi-row bearing may necessitate replacement of the entire bearing, resulting in high repair costs. Therefore, the present invention provides a cylindrical roller bearing assembly to address the issues raised in the background technology above. Utility Model Content

[0005] The purpose of the utility model is to provide a cylindrical roller bearing assembly, in which the cylindrical roller bearing is firmly connected through a simple connection structure, can more easily adapt to different length and load-bearing capacity requirements, and when repairing or replacing, only the damaged or worn single-row bearing needs to be replaced, without replacing the entire multi-row bearing, thereby reducing maintenance costs and having strong practicality.

[0006] To achieve the above objectives, a cylindrical roller bearing assembly is provided, comprising two adjacent outer rings and an inner ring disposed inside the outer rings, wherein a plurality of U-shaped embedding grooves are uniformly formed inside the outer rings, and a connecting assembly is commonly provided inside each two adjacent embedding grooves, wherein the connecting assembly is used to securely connect the outer rings.

[0007] The connecting assembly includes a connecting plate inserted into the embedded groove, two positioning plates symmetrically fixedly connected to the connecting plate on one side close to the outer ring, and two screws inserted into the corresponding positioning plates. The positioning plate is connected to the internal thread of the corresponding outer ring through the screws, and a threaded groove is opened inside the outer ring to cooperate with the screws.

[0008] According to the cylindrical roller bearing assembly, a gap is set between the end of the inner ring and the end of the outer ring.

[0009] According to the cylindrical roller bearing assembly, a hexagonal inner groove is provided inside the screw head, and the connecting assembly also includes a baffle provided on one side of the hexagonal inner groove and an insert fixedly connected to the baffle on the side close to the screw, and the insert is cooperatively connected with the hexagonal inner groove.

[0010] According to the cylindrical roller bearing assembly, the outer surface of the baffle is flush with the outer surface of the outer ring.

[0011] According to the cylindrical roller bearing assembly, the connecting plate is flush with the outer surface of the outer ring.

[0012] According to the cylindrical roller bearing assembly, a notch is formed on one side of the blocking piece.

[0013] The utility model has the following beneficial effects:

[0014] Compared to existing technologies, this cylindrical roller bearing assembly achieves a secure connection through a simple connection structure, making it easier to adapt to different length and load-bearing capacity requirements. Single-row bearings are also relatively simple to manufacture and can be standardized. By using connecting plates of varying lengths, bearings with varying numbers of rows can be manufactured. Furthermore, by combining multiple single-row bearings into a multi-row bearing, repair or replacement requires only replacing damaged or worn single-row bearings, rather than replacing the entire multi-row bearing. This reduces maintenance costs and enhances practicality.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] Reference Figure 1-5 , an embodiment of the present invention provides a cylindrical roller bearing assembly, which includes two adjacent outer rings 1 and an inner ring 2 arranged on the inner side of the outer ring 1. A plurality of U-shaped embedding grooves 5 are evenly opened inside the outer ring 1. A connecting component is commonly provided inside each two adjacent embedding grooves 5. The connecting component is used for fixed connection between the outer rings 1. The connecting component includes a connecting plate 3 inserted into the embedding groove 5, two positioning plates 6 symmetrically fixedly connected to the connecting plate 3 on the side close to the outer ring 1, and two screws 7 inserted into the corresponding positioning plates 6. The positioning plate 6 is threadedly connected to the corresponding outer ring 1 through the screws 7. A threaded groove 11 cooperating with the screws 7 is opened inside the outer ring 1.

[0026] After the outer ring 1 is fitted, the connecting plate 3 is snapped into the recessed groove 5 and screwed together with the outer ring 1 using screws 7. This secures the connecting plate 3 to the outer ring 1, thus completing the assembly of the cylindrical roller bearing. This simple operation allows for a secure connection of the cylindrical roller bearing. Cylindrical roller bearings achieve a secure connection through a simple connection structure, making it easier to adapt to varying lengths and load capacities. Single-row bearings are relatively simple to manufacture and can be standardized. Using connecting plates 3 of varying lengths allows for the manufacture of bearings with varying numbers of rows. Furthermore, by combining multiple single-row bearings into a multi-row bearing, repair or replacement requires only replacing the damaged or worn single-row bearing, rather than replacing the entire multi-row bearing. This reduces maintenance costs and enhances practicality.

[0027] The head of each screw 7 is provided with a hexagonal socket 9, which facilitates the use of an external hexagonal wrench to remove and install the screw 7. The connection assembly also includes a baffle 4 positioned on one side of the hexagonal socket 9 and an insert 10 fixedly connected to the baffle 4 on the side closest to the screw 7. The insert 10 is connected to the hexagonal socket 9. The baffle 4 is provided with a notch 8 on one side to facilitate the use of a tool to remove the baffle 4 through the notch 8.

[0028] After the screw 7 is installed, a blocking piece 4 is inserted on one side of the screw 7 so that the insert 10 is connected with the hexagonal socket 9. The blocking piece 4 protects the screw 7, which helps to ensure the overall aesthetics of the outer side of the cylindrical roller bearing.

[0029] The gap between the end of the inner ring 2 and the end of the outer ring 1 is set. When the outer rings 1 are fitted together for assembly, the inner rings 2 are spaced apart to ensure the flexible operation of the bearing and avoid additional stress caused by excessive tight fitting.

[0030] To ensure the flatness of the cylindrical roller bearing surface, the outer surface of the baffle 4 is flush with the outer surface of the outer ring 1, and the connecting plate 3 is flush with the outer surface of the outer ring 1. The cylindrical roller bearing with a flat surface can ensure normal installation work in the later stage.

[0031] Working Principle: After the outer ring 1 is fitted, the connecting plate 3 is snapped into the embedded groove 5 according to the required use. The connecting plate 3 and the outer ring 1 are then connected using screws 7 to secure the connecting plate 3 and the outer ring 1, thereby achieving a simple combination of cylindrical roller bearings. Cylindrical roller bearings achieve a secure connection through a simple connection structure, making it easier to adapt to different lengths and load-bearing capacity requirements. Single-row bearings are relatively simple to manufacture and can be standardized. Using connecting plates 3 of different lengths allows for the manufacture of bearings with different numbers of rows. Furthermore, by combining multiple single-row bearings into a multi-row bearing, repair or replacement requires only replacing the damaged or worn single-row bearing, rather than the entire multi-row bearing. This reduces maintenance costs and enhances practicality.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
