Description

Technical Field

[0001] This utility model relates to the field of guide wheel shaft technology, specifically a robust and pressure-resistant guide wheel shaft with high-efficiency transmission. Background Technology

[0002] Nylon guide wheel shafts are guide wheel assemblies made primarily of nylon, consisting of a central shaft and a nylon wheel body. They are used to guide, support, and protect cables, ropes, or other flexible materials to pass smoothly through equipment during operation. Nylon guide wheel shafts are widely used in various fields of modern industry, making them an ideal replacement for traditional metal guide wheels. When selecting a nylon guide wheel shaft, the appropriate material and structural design should be chosen based on the specific application scenario, load conditions, and environmental factors to maximize its performance advantages.

[0003] The guide wheel shaft can rotate when installed on the shaft body. Since the guide wheel shaft mainly guides through rotation, it needs to have good lubrication to ensure the transmission effect. However, after long-term use, the existing guide wheel shaft will experience a decrease in lubrication effect and requires the addition of lubricating oil. When adding lubricating oil, it can only be added to the outside, which makes it difficult for the lubricating oil to enter the rotating component evenly for lubrication.

[0004] In view of this, it is necessary to develop a robust and pressure-resistant guide shaft with high-efficiency transmission, which would make it easier for workers to add lubricating oil to the inside of the guide shaft. Utility Model Content

[0005] The purpose of this invention is to provide a robust and pressure-resistant guide wheel shaft with high-efficiency transmission, in order to solve the technical problem mentioned in the background art that when adding lubricating oil to the existing guide wheel shaft, the lubricating oil can only be added to the outside, which makes it difficult for the lubricating oil to enter the peripheral components evenly for lubrication.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a robust and pressure-resistant guide wheel shaft with high-efficiency transmission, comprising: a guide wheel shaft body, the guide wheel shaft body including a shaft body and a limiting disc, the limiting disc being located at both ends of the shaft body and integrally formed with the shaft body, an oil guiding assembly being provided inside the shaft body, the oil guiding assembly being used to provide a channel for the uniform transmission of lubricating oil, the oil guiding assembly including an oil guiding groove, an oil filling port and a through hole, the oil guiding groove being opened inside the shaft body, the oil filling port being opened at both ends of the oil guiding groove and penetrating the outer side of the limiting disc, and the through hole penetrating the inner wall of the shaft body.

[0007] Preferably, the inside of the filler port is provided with a sealing plug, and a blocking mesh is provided at the connection between the through hole and the oil guide groove.

[0008] Preferably, the shaft body has multiple mounting cavities inside, and the mounting cavities are arranged around the inside of the shaft body, with a support ring inside each mounting cavity.

[0009] Preferably, a bushing is installed in the internal cavity of the shaft, and the top of the bushing has a hole corresponding to the through hole, and the hole penetrates the top inner wall of the bushing.

[0010] Preferably, a matching rotating shaft 5 is rotatably mounted inside the bushing.

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

[0012] In this invention, since the rotating shaft is located inside the bushing, lubricating oil needs to be added to ensure its lubrication and make the transmission of the guide wheel shaft more efficient. To ensure that the lubricating oil is added more evenly, an oil guide assembly is provided. The operator removes the sealing plug from the filling port and pushes the lubricating oil into the oil guide groove using tools such as a syringe. There are two filling ports to facilitate the even addition of lubricating oil. After the lubricating oil is added, when the guide wheel shaft rotates, centrifugal force is generated, which causes the lubricating oil to enter evenly between the bushing and the rotating shaft through the through hole. The blocking mesh is used to block the added lubricating oil to prevent it from entering directly through the through hole after being added, which would result in uneven lubricating oil addition.

[0021] Please see Figures 1-4 A robust and pressure-resistant guide shaft for high-efficiency transmission;

[0022] It includes: a guide wheel shaft body 1, which includes a shaft body 2 and a limiting disk 3. The limiting disk 3 is located at both ends of the shaft body 2 and is integrally formed with the shaft body 2. An oil guiding assembly is provided inside the shaft body 2. The oil guiding assembly is used to provide a channel for the uniform transmission of lubricating oil. The oil guiding assembly includes an oil guiding groove 8, an oil filling port 9 and a through hole 11. The oil guiding groove 8 is opened inside the shaft body 2. The oil filling port 9 is opened at both ends of the oil guiding groove 8 and penetrates the outer side of the limiting disk 3. The through hole 11 penetrates the inner wall of the shaft body 2. A sealing plug 10 is provided inside the oil filling port 9. A blocking net 12 is provided at the connection between the through hole 11 and the oil guiding groove 8.

[0023] The guide wheel shaft body 1 is made of nylon, which has good wear resistance and impact resistance. The shaft body 2 and the limiting plate 3 are integrated as a whole. When the guide wheel shaft body 1 is in use, objects pass through the outside of the shaft body 2. The limiting plate 3 can limit the objects passing through the guide wheel shaft body 1 to prevent them from falling off the outside of the shaft body 2. Since the rotating shaft 5 is inside the bushing 4, lubricating oil needs to be added to ensure its lubrication and make the transmission of the guide wheel shaft body 1 more efficient. In order to make the lubricating oil added more evenly, an oil guide component is provided. The operator removes the sealing plug 10 from the oil filling port 9 and pushes the lubricating oil into the oil guide groove 8 through a syringe or other tools. There are two oil filling ports 9 to facilitate the even addition of lubricating oil. After the lubricating oil is added, when the guide wheel shaft body 1 is rotated, centrifugal force is generated, which causes the lubricating oil to enter evenly between the bushing 4 and the rotating shaft 5 through the through hole 11. The blocking net 12 is used to block the added lubricating oil to prevent the lubricating oil from entering directly through the through hole 11 after being added, which would result in uneven lubricating oil addition.

[0024] The shaft 2 has multiple mounting cavities 6 inside, and the mounting cavities 6 are opened around the inside of the shaft 2. A support ring 7 is provided inside the mounting cavity 6. A bushing 4 is installed in the internal cavity of the shaft 2, and a hole corresponding to the through hole 11 is opened on the top of the bushing 4. The hole penetrates the top inner wall of the bushing 4. A matching rotating shaft 5 is rotatably installed inside the bushing 4.

[0025] The interior of the mounting cavity 6 provides space for the installation of the support ring 7. The support ring 7 is injection molded and embedded inside. The support ring 7 is made of steel and is used to improve the strength of the shaft 2, making the guide wheel shaft body 1 more robust and pressure resistant. The rotating shaft 5 is rotatably installed inside the bushing 4. After the guide wheel shaft body 1 is installed by rotating the shaft 5, the shaft 2 can be rotated for use.

[0026] Working principle: First, the guide wheel shaft body 1 is installed via the rotating shaft 5. Since the rotating shaft 5 is rotatably connected to the bushing 4, the guide wheel shaft body 1 can rotate. The object that needs to be guided and supported is guided and transmitted through the shaft body 2. The limiting plate 3 plays a limiting role. When it is necessary to add lubricating oil inside, the operator can open the sealing plug 10 and add the lubricating oil into the oil guide groove 8 through the filling port 9. Then, the filling port 9 is sealed by the sealing plug 10. When the guide wheel shaft body 1 is in use, it will rotate and generate centrifugal force, so that the lubricating oil in the oil guide groove 8 enters the interior through the through hole 11 for lubrication.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
