Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings for rolling mills, in particular to a width-adjustable movable-pressure sliding bearing for rolling mills. Background Art
[0002] In the field of mechanical manufacturing, rolling mills are important equipment widely used in industries such as metal processing and plastic forming. The performance of a rolling mill largely depends on the design and function of its key component - the bearing. The bearing not only needs to withstand high loads and high-speed operation but also maintain precise motion control to ensure the processing quality of products. Traditional rolling mill bearings are usually designed with fixed dimensions, which, although ensuring the stability and reliability of the equipment to a certain extent, also bring certain limitations.
[0003] Especially during the production process, products of different specifications have different requirements for the width of the rolling mill bearing. Traditional bearings with fixed widths do not have the function of adjusting the width. Therefore, when it is necessary to change the product specifications, it is often necessary to stop the machine to replace the bearing or adjust the equipment, which not only reduces production efficiency but also increases production costs. In addition, the maintenance and replacement of fixed bearings are cumbersome and require professional technicians to operate, further increasing the operation difficulty and cost of the enterprise.
[0004] The non-adjustability of traditional fixed-width bearings limits the flexibility and adaptability of rolling mills. To solve this problem, it is necessary to develop a new type of bearing for rolling mills, which should have the function of adjustable width to meet the production needs of different products and simplify the maintenance and replacement process, thereby improving production efficiency and economic benefits.
[0005] Therefore, we propose a width-adjustable movable-pressure sliding bearing for rolling mills. Summary of the Utility Model
[0006] The utility model mainly solves the above-mentioned existing technical problems and provides a width-adjustable movable-pressure sliding bearing for rolling mills.
[0007] To achieve the above purpose, the utility model adopts the following technical scheme. A width-adjustable movable-pressure sliding bearing for rolling mills includes a main bearing body. A circumferential docking groove is opened at the outer edge of the main bearing body, and a limiting rod is installed on the outer end face of the main bearing body. A plurality of auxiliary bearings that overlap the outer end face of the main bearing body are slidably sleeved on the limiting rod. Docking teeth one and docking teeth two are horizontally staggered on both sides of the auxiliary bearing. Adjacent auxiliary bearings are spliced respectively through the staggered docking teeth one and docking teeth two. A nut is threadedly connected to the limiting rod, and the plurality of spliced auxiliary bearings are detachably connected to the main bearing body through the nut.
[0008] Preferably, a fixing bolt is threadedly connected to the outer side of each of the first docking teeth. A second fixing hole located outside the auxiliary bearing is formed between adjacent second docking teeth. The first docking teeth on the auxiliary bearing close to the main bearing body are threadedly connected to the first fixing hole formed in the inner bottom surface of the docking groove through the fixing bolts on the outer sides of the first docking teeth.
[0009] Preferably, the limiting rods on the main bearing body are annularly distributed at its edge, and the number of the limiting rods is at least three groups.
[0010] Preferably, both the first docking teeth and the second docking teeth are stainless steel bumps.
[0011] Preferably, an elastic sealing ring is sleeved at the connection between the main bearing body and the adjacent auxiliary bearing. The sealing ring includes a protective sleeve and an elastic block on the inner side of the protective sleeve for one circle, and the elastic block shields the outer port of the corresponding first fixing hole.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] Embodiment: A width-adjustable movable pressure sliding bearing for a rolling mill, as Figure 1 - Figure 4 shown, includes a main bearing body 1. A circumferential docking groove 101 is provided at the outer edge of the main bearing body 1. A limiting rod 102 is also installed on the outer end face of the main bearing body 1. A plurality of sub-bearings 2 that overlap the outer end face of the main bearing body 1 are slidably sleeved on the limiting rod 102. Docking teeth one 201 and docking teeth two 202 are horizontally staggered on both sides of the sub-bearing 2. Adjacent two sub-bearings 2 are spliced respectively through the staggered docking teeth one 201 and docking teeth two 202. A nut 103 is threadedly connected to the limiting rod 102. Through the nut 103, the plurality of sub-bearings 2 spliced into one body are detachably connected to the main bearing body 1.
[0028] Furthermore, a fixing bolt 203 is threadedly connected to the outside of each docking tooth one 201. A fixing hole two 204 located outside the sub-bearing 2 is provided between adjacent docking teeth two 202. Through the corresponding fixing bolt 203 being threadedly connected to the fixing hole two 204, the docking tooth one 201 on the sub-bearing 2 close to the main bearing body 1 is threadedly connected to the fixing hole one 104 provided on the inner bottom surface of the docking groove 101 through the fixing bolt 203 outside the docking tooth one 201. Adjacent sub-bearings 2 are clamped through the staggered docking teeth one 201 and docking teeth two 202, and then a plurality of groups are fixed by using the corresponding fixing bolts 203. Each adjacent pair of sub-bearings 2 is strengthened once, improving the connection stability of the overall splicing state. Especially when the main bearing body 1 drives a plurality of sub-bearings 2 to rotate at high speed, the adjacent sub-bearings 2 are already fixed at one circle of the connection part itself, improving the connection stability of the overall spliced sub-bearings 2.
[0029] Furthermore, the limiting rods 102 on the main bearing body 1 are annularly distributed at its edge, and the number of the limiting rods 102 is at least three groups. The plurality of limiting rods 102 can limit the sliding of the plurality of sub-bearings 2 sleeved on them, playing an effect of guiding the installation. The limiting rods 102 penetrate through both sides of the corresponding sub-bearings 2.
[0030] Furthermore, both the docking teeth one 201 and the docking teeth two 202 are made of stainless steel convex blocks.
[0031] Furthermore, a sealing ring with elasticity is sleeved at the connection between the main bearing body 1 and the adjacent auxiliary bearing 2. The sealing ring includes a protective sleeve 3 and an elastic block 301 on the inner side of the protective sleeve 3. The elastic block 301 blocks the outer port of the corresponding fixing hole 104, preventing the fixing bolt 203 at the connection between the main bearing body 1 and the auxiliary bearing 2 from falling off, and also playing a role in blocking and protecting the connection part.
[0032] The working principle of the present utility model: This technical solution uses the limiting rod 102 for limiting, and the butt teeth 201, butt teeth 202 and butt groove 101 are matched for clamping, and there are also two threaded connections of the fixing bolt 203 and the nut 103. Multiple groups of connection and limiting methods are combined to improve the connection stability and fixing effect of the main bearing body 1 after the width adjustment strip. At the same time, multiple groups of spliced auxiliary bearings 2 can also be spliced first and then directly replace multiple groups of auxiliary bearings 2 used on the outer side of the main bearing body 1, and different width solutions can be quickly replaced or adjusted without delaying the width adjustment efficiency of the outer side of the main bearing body 1.
[0033] A width-adjustable pressure sliding bearing for a rolling mill. It has the following beneficial effects:
[0034] Improve connection stability: Through the combined use of the limiting rod 102, the butt teeth 201 and butt teeth 202 of the auxiliary bearing 2, and the fixing bolt 203, the firm connection and precise positioning of the auxiliary bearing are realized. When the main bearing body 1 drives multiple groups of auxiliary bearings 2 to rotate at high speed, this design ensures high connection stability and significantly reduces mechanical failures that may be caused by loose connections.
[0035] Convenient and quick adjustment and maintenance: Due to the design of the limiting rod 102 and the threaded connection (fixing bolt 203 and nut 103), the replacement and width adjustment of the auxiliary bearing 2 become fast and convenient. Users can quickly adjust the bearing width according to different production requirements, improving the adaptability and production efficiency of the equipment.
[0036] Improve the sealing and protection of the device: The connection between the main bearing body 1 and the auxiliary bearing 2 is designed with an elastic sealing ring, which contains a protective sleeve 3 and an elastic block 301. This not only enhances the sealing performance, prevents dust and moisture from entering, but also protects the fixing bolt 203 from falling off easily, thereby improving the protection and durability of the overall device.
[0037] Reduce operating noise and improve equipment safety: The firmness of the structure and the application of the elastic sealing ring effectively reduce the vibration and noise generated during high-speed movement, providing a safer and more comfortable working environment for operators.
[0038] Improvement in economic benefits: Due to the high reliability and easy maintainability of this design, the daily operation and maintenance costs and downtime are reduced. In the long run, it can bring significant economic benefits to the using enterprises. In addition, the characteristic of quick adjustment enables the equipment to rapidly adapt to the production of different products, enhancing the market competitiveness.
[0039] Through these designs, the width-adjustable pressure sliding bearing for rolling mills of the present utility model not only has a significant improvement in functionality, but also brings multiple advantages in operation efficiency and economic benefits, and is suitable for wide application in industrial occasions that require frequent adjustment of the bearing width.
