Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed wire production lines, and particularly relates to a pedestal bearing used for the first-stage roller table of a high-speed wire roller table. Background Art

[0002] One of the key equipment in the high-speed wire production line - the technical improvement of the Stelmor air-cooled roller table (referred to as the S / M roller table), especially an innovative solution is proposed for the bearing lubrication and maintenance problems of its first-stage roller table in extreme working environments.

[0003] During the high-speed wire production process, the S / M roller table, as an important transmission device connecting the spinning machine and the subsequent cooling section, undertakes the task of quickly and smoothly transporting high-temperature wire. Among them, the first-stage roller table is directly arranged at the outlet of the spinning machine. Due to the influence of the initially high-temperature wire and cooling air in this area, a special working condition with dense rollers, low space position, and extremely high ambient temperature is formed. In this environment, the stability and durability of the roller table system become the key factors affecting production efficiency and product quality.

[0004] Traditionally, ordinary UCPA-type bearing seats are used for the roller tables in this area. Please refer to Figure 3 , and rely on a centralized dry oil lubrication system for lubrication. However, when facing the high-temperature environment of the first-stage roller table, this lubrication method exposes a series of serious problems: First, the high temperature causes the lubricating oil to easily solidify, which not only reduces the lubrication effect but also frequently causes blockage of the lubrication pipeline, seriously affecting the normal operation of the roller table and the bearing life; Second, since the design height of the roller table is mostly below the daily maintenance plane, once the bearing seat fails and needs to be repaired or replaced, the operator faces great difficulty in disassembly and assembly, which not only increases the maintenance cost but also prolongs the downtime, posing a serious threat to production continuity.

[0005] In summary, the existing dry oil lubrication system and bearing seat configuration are difficult to meet the requirements of efficient and stable operation of the first-stage S / M roller table of the high-speed wire production line under extreme working conditions. Therefore, the utility model designs a pedestal bearing used for the first-stage roller table of a high-speed wire roller table, which replaces dry oil lubrication with oil-air lubrication. Summary of the Utility Model

[0006] Aiming at the problems existing in the prior art, the utility model provides a pedestal bearing used for the first-stage roller table of a high-speed wire roller table. This bearing seat can use oil-air lubrication, with the characteristics of improving the lubrication effect, reducing the failure rate, and short maintenance time.

[0007] The utility model is realized as follows. A pedestal bearing used for the first section of the roller table of high-speed wire rod roller tables includes a bearing pedestal and a bearing installed in the bearing pedestal. It is characterized in that: the bearing installed in the bearing pedestal is a single-side sealed bearing; a grease retainer ring is arranged in the bearing pedestal on the side opposite to the sealing surface of the single-side sealed bearing; the grease retainer ring and the single-side sealed bearing enclose a sealed cavity; an oil injection hole is arranged on the bearing pedestal corresponding to the position of the single-side sealed bearing in the radial direction, and an oil plug is installed on the oil injection hole; a snap ring is installed outside the grease retainer ring.

[0008] Further preferably, the bearing pedestal includes a horizontal base and a bearing support part, and mounting holes are arranged on both the upper and lower end surfaces of the base.

[0009] Further preferably, a set screw is arranged on the inner ring of the single-side sealed bearing on the side of the horizontal base, and an open adjustment hole is arranged on the outer edge of the bearing support part of the bearing pedestal corresponding to the position of the set screw.

[0010] The advantages and technical effects of the utility model are as follows: In view of the special working conditions of the first section of the roller table of the S / M roller table (i.e., the Stelmor air-cooled roller table) in the high-speed wire rod production line, the utility model innovatively designs a pedestal bearing suitable for oil-gas lubrication, aiming to replace the traditional dry oil lubrication method and solve problems such as the solidification and blockage of lubricating oil caused by high temperature and the difficulty in disassembling and assembling the bearing pedestal. The design of the bearing pedestal is ingenious and is mainly reflected in the following aspects:

[0011] Firstly, a single-side sealed bearing is adopted in the bearing pedestal, and a grease retainer ring is arranged on the side opposite to its sealing surface. The grease retainer ring and the bearing enclose a sealed cavity together. This design not only ensures the effective implementation of oil-gas lubrication, but also significantly improves the lubrication effect and reduces the failure rate caused by poor lubrication. At the same time, the oil injection hole arranged on the bearing pedestal and the installed oil plug facilitate the injection and replacement of lubricating oil.

[0012] Secondly, the snap ring installed outside the grease retainer ring not only stabilizes the position of the grease retainer ring, but also makes the disassembly and assembly process of the bearing pedestal simpler and faster, greatly shortening the maintenance time and reducing the maintenance cost.

[0013] In addition, the structural design of the bearing pedestal has also been optimized, including a horizontal base and a bearing support part. Mounting holes are arranged on both the upper and lower end surfaces of the base, enhancing the connection stability between the bearing pedestal and the roller table bracket. In particular, a set screw is arranged on the inner ring of the single-side sealed bearing on the side of the horizontal base, and an open adjustment hole is arranged at the corresponding position. This design facilitates the fine adjustment of the set screw and ensures the stability and accuracy of the bearing during operation. Description of the Drawings

[0018] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figure 1 and Figure 2 , a pedestal bearing used for the first section of the high-speed wire rod roller table, including a bearing housing 1 and a bearing 2 installed in the bearing housing. The characteristics are as follows: The bearing installed in the bearing housing is a single-sided sealed bearing. The design of the single-sided sealed bearing can effectively prevent the lubricant from leaking from one side of the bearing, ensuring the effective utilization of the lubricant inside the bearing. This sealing performance helps to improve the lubrication effect, reduce the waste of lubricant, and protect the bearing from the intrusion of external pollutants, thereby extending the service life of the bearing; on the opposite side of the sealing surface of the single-sided sealed bearing, an oil baffle ring 3 is provided inside the bearing housing. The oil baffle ring and the single-sided sealed bearing enclose a sealed cavity. This design further enhances the sealing performance of the bearing. The sealed cavity can ensure that when oil-air lubrication is carried out, the lubricant can be evenly distributed inside the bearing, reducing friction and wear, and improving the operating efficiency and stability of the bearing; along the radial direction on the bearing housing corresponding to the position of the single-sided sealed bearing, a lubricating oil hole 4 is provided, and an oil plug 5 is installed on the lubricating oil hole. The design of the lubricating oil hole facilitates the injection and replacement of the lubricant, and the installed oil plug can ensure that the sealing performance of the sealed cavity is not affected when the lubricant does not need to be injected. This design improves the convenience of bearing maintenance, enabling the operator to easily replenish and replace the lubricant; an elastic snap ring 6 is installed outside the oil baffle ring. The installation of the elastic snap ring not only stabilizes the position of the oil baffle ring, but also ensures the tight fit between the oil baffle ring and the bearing housing. This design helps to prevent the lubricant from leaking from the gap between the oil baffle ring and the bearing housing, further improving the sealing performance and lubrication effect of the bearing. At the same time, the elastic snap ring also has a certain buffering effect, which can reduce the impact and vibration received by the bearing during operation.

[0020] Further preferably, the bearing seat includes a horizontal base 1-1 and a bearing support portion 1-2, and mounting holes 1-3 are provided on both the upper and lower end surfaces of the base.

[0021] It is mainly reflected in the following aspects:

[0022] I. Enhancing installation stability and reliability

[0023] Multi-point fixation: By providing mounting holes on both the upper and lower end surfaces of the base, multi-point fixation of the bearing seat can be achieved. This multi-point fixation method can more effectively resist the vibration and impact forces generated during the operation of the equipment, reduce the loosening and displacement of the bearing seat caused by vibration, and thus improve the operation stability and reliability of the entire roller table system.

[0024] Improving load-bearing capacity: Multi-point fixation also means that the bearing seat can more evenly distribute and bear the weight from the rolled piece and the equipment itself, avoiding local stress concentration caused by excessive single-point load-bearing, and thus improving the load-bearing capacity and service life of the bearing seat.

[0025] II. Facilitating installation and maintenance

[0026] Simplifying the installation process: Since mounting holes are provided on both the upper and lower end surfaces of the bearing seat, a more flexible choice of appropriate fixing positions and directions can be made during installation, thus simplifying the installation process and improving the installation efficiency.

[0027] Facilitating maintenance: When maintenance or replacement of the bearing seat is required, the multi-point fixation design also facilitates operators to operate from multiple angles, reducing the maintenance difficulty and shortening the maintenance time.

[0028] Adapting to different installation environments: Different production lines or equipment layouts may have different requirements for the installation position and direction of the bearing seat. By providing mounting holes on both the upper and lower end surfaces of the base, these different installation environments can be better adapted, improving the versatility and flexibility of the bearing seat.

[0029] Further preferably, a set screw 7 is provided on the inner ring of the single-side sealed bearing on the side of the horizontal base. The set screw is a T-shaped screw, which is used to cooperate with the keyway on the roller shaft to achieve torque transmission. An open adjustment hole 1-4 is provided on the outer edge of the bearing seat support portion corresponding to the position of the set screw. This design not only realizes effective cooperation with the roller shaft, ensures stable torque transmission, and improves the transmission efficiency of the equipment; at the same time, an open adjustment hole is cleverly opened on the outer edge of the bearing seat support portion corresponding to the position of the set screw. This design greatly facilitates the precise adjustment of the set screw by the staff, effectively ensuring the operation stability and service life of the bearing, and also significantly improving the flexibility and convenience of equipment installation and maintenance.

[0030] In summary, the oil-gas lubricated pillow block bearing of the present utility model provides strong technical support for the continuous and stable operation of the high-speed wire rod production line with its efficient lubrication effect, simple disassembly and assembly process, stable structural design and the ability to adapt to extreme working conditions, significantly improving the production efficiency and product quality.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
