Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate production equipment, and in particular relates to a split roller transmission device. Background Art

[0002] In the plate production process, hot-rolled steel plates need to go through a specific cooling process to ensure their physical and mechanical properties. This cooling process is usually completed on a cooling bed, and the roller drive is the core component of the cooling bed. The roller drive is powered by a motor and is driven by orderly arranged roller shafts. Each set of roller shafts is equipped with two sets of rollers to provide stable support.

[0003] However, since this device operates in a high temperature environment for a long time, the rollers and rollers on the shaft will inevitably wear out. With the advancement of industrial efficiency development, the frequency of equipment use has increased significantly, and the demand for rapid handling of equipment failures and low failure rate operation has become increasingly urgent. In this case, reducing equipment failure rates and simplifying maintenance processes have become key factors in improving work efficiency.

[0004] Traditional roller transmission devices usually adopt an integral roller design, which means that when replacing a damaged roller, no matter from which direction the operation is performed, multiple adjacent rollers and sleeves need to be disassembled to complete the replacement. This replacement method is not only inefficient, but also labor-intensive, which seriously restricts production efficiency and the convenience of equipment maintenance.

[0005] In view of the above problems, the utility model proposes a split roller transmission device, which aims to realize barrier-free replacement of damaged rollers without removing the surrounding rollers and sleeves. Through this innovative design, work efficiency can be significantly improved, while the difficulty of maintenance can be greatly reduced, thus meeting the needs of modern industrial production for high efficiency and low failure rate of equipment. Utility Model Content

[0006] In view of the problems existing in the prior art, the utility model provides a split roller transmission device which is easy to disassemble and replace, improves the convenience of equipment maintenance, reduces the difficulty of maintenance, and at the same time ensures the stability and precision of the roller transmission.

[0007] The utility model is implemented as follows: a split roller transmission device, characterized in that it includes: a split roller, composed of a convex half disc and a concave half disc, which are detachably connected together; a roller shaft, the split roller is installed on the roller shaft, each roller shaft is equipped with a plurality of split rollers, and a specified spacing is maintained between each split roller; a sleeve is installed at both ends of the roller shaft; one end of the roller shaft is connected to a motor reducer; a connecting shaft is used to connect the sleeves on two adjacent roller shafts; wherein the joint surfaces of the convex half disc and the concave half disc are fixedly connected together by a bolt assembly.

[0008] Preferably, the convex half disk and the concave half disk can form a complete circular rolling disk after docking. Preferably, a through hole is provided on the joint surface of the convex half disk and the concave half disk, and a bolt assembly is installed in the through hole.

[0009] Preferably, the bolt assembly in the through hole is a metric bolt and a reamed hole bolt.

[0010] Preferably, the metric bolts and the reamed hole bolts are distributed in a diagonal manner on the joint surface of the convex half disk and the concave half disk.

[0011] Preferably, when the convex half-disc and the concave half-disc are butted against each other, their outer edges are smoothly transitioned. Preferably, at least one of the joint surfaces of the convex half-disc and the concave half-disc is provided with a positioning stop.

[0012] Preferably, positioning pins are further provided on the joint surfaces of the convex half-disc and the concave half-disc.

[0013] The advantages and technical effects of the utility model are mainly reflected in the following aspects: Radial stability: Through the design of the concave and convex surface, the radial movement of the split roller is effectively constrained, which not only enhances the stability of the roller, but also makes it easier to position and perform fine processing, thereby improving the working accuracy and service life of the entire transmission device.

[0014] Axial positioning and damage resistance: The bolt design on the joint surface cleverly meets the connection requirements of the roller and provides reliable axial positioning. This design also enhances the roller's ability to resist tangential force damage when encountering jamming, thereby improving the durability and reliability of the equipment.

[0015] Easy to disassemble and maintain: Compared with the traditional integral roller, the split roller design of the utility model makes the disassembly process easier. The two half-discs can be easily separated by simply removing the connecting bolts, without the need to be inserted into the roller shaft through a complex axial path like an integral roller. This feature greatly simplifies the maintenance process, reduces work intensity, and improves work efficiency. In summary, the utility model realizes the rapid replacement and convenient maintenance of the roller through a unique design scheme, significantly improves the ease of use and maintainability of the equipment, reduces operating costs, and brings substantial technological progress to related industries.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0031] The utility model provides a split roller transmission device. Figures 1 to 6 :The device mainly includes a split roller 1, a roller shaft 2, a sleeve 3, a connecting shaft 4 and a motor reducer 5. The split roller 1 is composed of a convex half-disc 1-1 and a concave half-disc 1-2, which are detachably connected together by bolts. A plurality of such split rollers 1 are installed on the roller shaft 2, and a specified spacing is maintained between each roller. The sleeve 3 is installed at both ends of the roller shaft 2 for connection and fixation. The connecting shaft 4 is used to connect the sleeves 3 on two adjacent roller shafts so that the entire device forms a stable transmission system. The motor reducer 5 is connected to one end of the roller shaft 2 to provide power for the device.

[0032] Through holes are provided on the joint surfaces 1-5 and 1-7 of the convex half disk 1-1 and the concave half disk 1-2. These through holes include conventional through holes 1-9 and matching through holes 1-10, which are used to install metric bolts 1-4 and reamed hole bolts 1-3 respectively. For specific arrangement, see Figure 3b , Figure 3d , Figure 5b This design not only meets the connection requirements of the roller, but also provides reliable axial positioning, and enhances the ability of the roller to resist tangential force damage when encountering blocking. The conventional through hole 1-9 does not have a matching relationship with the metric bolt 1-4; while the reamed hole bolt 1-3 and the matched through hole 1-10 need to have a matching relationship, which plays an axial positioning role. Figure 5c An example of the connection between a reamed hole bolt and a matching through hole is shown in the figure. As shown in the figure, the diameter D of the matching screw hole 1-10 should not be less than the diameter d of the screw rod of the reamed hole bolt. On this basis, the size of the matching screw hole 1-10 is recommended to adopt the basic hole system H7 tolerance.

[0033] In addition, the joint surface of the convex half disc 1-1 and the concave half disc 1-2 is very delicately designed, and the shape of the concave and convex surface can effectively restrict the radial movement of the split roller, making it easier to position and finely process the outer rim surface. Moreover, after the two half discs are butt-jointed, their outer edges have a smooth transition, and there is no obvious protrusion at the joint, ensuring the stability of the roller during rotation.

[0034] from Figure 6 It can be seen more intuitively that if the roller at position Q is damaged, if an integral roller is used, multiple rollers and sleeves 3 need to be disassembled to replace it from any direction. However, if a split roller 1 is used, any roller on the roller shaft 2 can be replaced individually without any obstacles, and there is no need to remove the surrounding components, which greatly reduces the workload.

[0035] See also Figure 7a In order to further improve the positioning accuracy, a positioning pin 1-12 can be added to the joint surface of the convex half disk 1-1 and the concave half disk 1-2 and inserted into the positioning pin hole 1-11. At the same time, at least one half disk is provided with a positioning stop I1-6 and a positioning stop II1-8 for radial positioning.

[0036] See also Figure 7b In order to further increase the connection strength of the split roller 1, 8 through holes can be set on the joint surface I1-5 and the joint surface II 1-7 for connection, and a bolt is arranged in each through hole.

[0037] The main advantage of this split roller design is that it is easy to disassemble and maintain. Compared with the traditional integral roller, the two half-plates can be easily separated by removing the connecting bolts, which greatly simplifies the maintenance process, reduces the work intensity and improves the work efficiency.

[0038] In general, the utility model realizes the rapid replacement and convenient maintenance of the roller through a unique design scheme, significantly improves the usability and maintainability of the equipment, reduces operating costs, and brings substantial technological progress to related industries.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
