Description

Technical Field

[0001] This utility model belongs to the technical field of cylindrical roller bearings, specifically a cylindrical roller bearing with lubrication function. Background Technology

[0002] A radial rolling bearing with cylindrical rollers as the rolling elements has an internal structure in which the rollers are arranged in parallel and spacers or spacers are installed between them to prevent the rollers from tilting or rubbing against each other, thus effectively preventing an increase in rotational torque.

[0003] However, when modern cylindrical roller bearings need maintenance and lubrication after prolonged operation, they must be disassembled to perform internal lubrication. This method of lubrication greatly increases the intensity of the operation. In addition, since the lubricating oil injected into the cylindrical roller bearing contains impurities, these impurities may affect the lubrication function, causing the cylindrical roller bearing to malfunction. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cylindrical roller bearing with lubrication function. This solves the problem that currently, when cylindrical roller bearings need maintenance and lubrication after long-term rotation, the bearing must be disassembled to perform internal lubrication and maintenance. This lubrication and maintenance method greatly increases the intensity of operation. At the same time, because the lubricating oil injected into the cylindrical roller bearing contains impurities, these impurities may affect the lubrication function, causing the cylindrical roller bearing to malfunction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical roller bearing with lubrication function, comprising an outer ring, an inner cavity on the outer ring, a mounting bracket installed in the inner cavity, an oil inlet on the mounting bracket, two slots in the oil inlet, a sealing post slidably installed in the oil inlet, two locking blocks fixedly installed on the sealing post, and two oil outlet holes (first and second) on the mounting bracket.

[0006] As a further embodiment of this utility model: an inner ring is installed in the inner cavity, and the mounting bracket is installed between the outer ring and the inner ring.

[0007] As a further embodiment of this utility model: the mounting frame is provided with a plurality of mounting openings, and a rotating rod is installed in each mounting opening.

[0008] As a further embodiment of this utility model: a roller is installed on the rotating rod, and an opening hole is provided on the sealing post.

[0009] As a further embodiment of this utility model: an installation ring is slidably installed inside the oil inlet, and connecting rings are symmetrically installed on the installation ring.

[0010] As a further embodiment of this utility model: a filter plate is installed inside the mounting ring, and the filter plate has a plurality of filter holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This cylindrical roller bearing with lubrication function is equipped with a locking block, a locking groove, a mounting bracket, and an oil outlet. During operation, the operator places the bearing flat on a horizontal surface, places the tool on the opening hole, and then rotates the tool. The rotation of the tool causes the sealing column to rotate. Since the sealing column is symmetrically equipped with locking blocks that engage in the locking groove, the rotation of the sealing column will cause the locking blocks to rotate synchronously, thereby separating the locking blocks from the locking groove. Then, the sealing column is removed, and the oil injection pipe is pressed tightly against the oil injection port to inject oil into the bearing. After the lubricating oil enters the oil injection port, it flows out from the second oil outlet and the two first oil outlets on the mounting bracket, reaching the inner cavity, thus lubricating and maintaining the entire bearing. It is not necessary to completely disassemble the cylindrical roller bearing, reducing the operator's workload.

[0013] 2. This cylindrical roller bearing with lubrication function, through the setting of filter plate, filter holes, connecting ring and mounting ring, allows lubricating oil in the oil outlet pipe to enter the oil inlet during operation. It passes through the filter holes on the filter plate and enters the inner cavity. Impurities remaining in the lubricating oil are blocked by the filter plate. When the filter plate needs to be cleaned, the operator removes the sealing column, hooks the connecting ring with an iron hook, and then removes the mounting ring to clean the filter plate, preventing the filter holes from being blocked and ensuring the normal operation of subsequent work.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a cylindrical roller bearing with lubrication function, including an outer ring 1, an inner cavity 2 on the outer ring 1, an inner ring 3 installed in the inner cavity 2, and a mounting bracket 4 installed between the outer ring 1 and the inner ring 3.

[0021] An installation frame 4 is installed in the inner cavity 2. The installation frame 4 has several installation openings 5, and a rotating rod 6 is installed in the installation openings 5.

[0022] Rollers 7 are mounted on the rotating rod 6, and opening holes 12 are provided on the sealing column 11.

[0023] The mounting frame 4 has an oil inlet 10, and an installation ring 15 is slidably installed inside the oil inlet 10. A connecting ring 17 is symmetrically installed on the installation ring 15. Because the connecting ring 17 is symmetrically installed, workers can use an iron hook to hook onto the connecting ring 17, thereby removing the installation ring 15 from the oil inlet 10, which facilitates the subsequent replacement and installation of the installation ring 15.

[0024] A filter plate 16 is installed inside the mounting ring 15. The filter plate 16 has several filter holes 18. Because of the filter plate 16, impurities in the lubricating oil can be blocked outside the filter plate 16, preventing impurities from entering and affecting the lubrication function, thus ensuring that the cylindrical roller bearing can work normally.

[0025] Two slots 14 are provided inside the oil filling port 10. Because of the slots 14, the locking block 13 can be locked in the slots 14 to prevent the sealing column 11 from sliding out of the oil filling port 10, thus improving the stability of subsequent work.

[0026] A sealing post 11 is slidably installed inside the oil inlet 10. Because of the installation of the sealing post 11, the injected lubricating oil can be prevented from leaking out of the cylindrical roller bearing, thus avoiding waste and reducing operating costs.

[0027] Two locking blocks 13 are fixedly installed on the sealing column 11, and two oil outlet holes 8 are opened on the mounting frame 4. Because there are two oil outlet holes 8, lubricating oil can be evenly injected into the cylindrical roller bearing, so that the inside of the cylindrical roller bearing can be filled with lubricating oil, ensuring the normal use of the cylindrical roller bearing in the future.

[0028] The mounting frame 4 has an oil outlet hole 2 9.

[0029] The working principle of this utility model is as follows: When working, the operator places the bearing flat on a horizontal surface, then places the tool on the opening hole 12, and then rotates the tool. The rotation of the tool drives the sealing column 11 to rotate. Since the sealing column 11 is symmetrically equipped with locking blocks 13, and the locking blocks 13 are locked in the locking groove 14, the rotation of the sealing column 11 will drive the locking blocks 13 to rotate synchronously, thereby separating the locking blocks 13 from the locking groove 14. Then the sealing column 11 is removed, and then the oil injection pipe is pressed tightly against the oil injection port 10 to inject oil into the bearing. After the lubricating oil enters the oil injection port 10, it flows out from the oil outlet hole 2 9 and the two oil outlet holes 1 8 opened on the mounting frame 4 and reaches the inner cavity 2, thereby lubricating and maintaining the entire bearing.

[0030] When the lubricating oil in the oil outlet pipe enters the oil inlet 10, it will pass through the filter holes 18 on the filter plate 16 and enter the inner cavity 2. The impurities remaining in the lubricating oil will be blocked by the filter plate 16. When the filter plate 16 needs to be cleaned, the operator takes out the sealing column 11, hooks the connecting ring 17 with an iron hook, and then takes out the installation ring 15 to clean the filter plate 16.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
