Description

Technical Field

[0001] This utility model relates to the field of composite disc technology, and in particular to a steel-covered cast iron composite disc. Background Technology

[0002] Steel-capped cast iron composite discs are primarily used in heavy machinery, such as machine tool spindles, mining crushers, lifting transmission devices, and large gear transmission systems. In these applications, the fixed disc not only needs to withstand high-speed rotation and strong impact loads but also requires excellent wear resistance and dimensional stability. By adopting a steel-capped cast iron composite structure, the fixed disc can utilize both the high strength support provided by steel and the wear resistance of cast iron, effectively extending the equipment's service life and ensuring operational stability. This makes it particularly suitable for long-term, high-load industrial production environments.

[0003] In the existing technology, composite discs are prone to local or overall deformation when used for a long time or subjected to large external impacts. This may not only lead to accelerated wear on the surface of the fixed disc, but also affect the operating accuracy and transmission stability of mechanical equipment, and even cause vibration or failure under high load and high speed operation, thereby reducing the service life and reliability of the equipment. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a steel-covered cast iron composite disc, which aims to improve the problem in the prior art where composite discs are prone to local or overall deformation when used for a long time or subjected to large external impacts.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A steel-covered cast iron composite disc includes a fixed disc, the fixed disc having a hollow internal structure with a reinforcing structure inside, a mounting ring fixedly mounted on the fixed disc, a mounting disc inside the mounting ring, a positioning hole in the middle of the mounting disc, fixing teeth arranged in a ring on the inner side of the mounting disc, and fixing grooves arranged in a ring on the outer side of the mounting disc.

[0007] By adopting the above technical solutions, the fixed plate is fixed in a suitable position. The hollow structure inside the fixed plate not only reduces the weight, but also improves the overall strength and rigidity by strengthening the structure. The mounting ring is connected to the fixed plate, so that the mounting plate is firmly installed on the fixed plate. The positioning hole in the middle of the mounting plate is used for precise positioning, so that the fixed plate can bear the load during operation and ensure the precise alignment of each connecting part.

[0008] Preferably, the reinforcing structure includes a first reinforcing rib, which is fixedly disposed within a hollow structure inside the fixed disk, and the first reinforcing rib is configured as a honeycomb structure.

[0009] Preferably, the reinforcing structure includes a second reinforcing rib, which is fixedly disposed within a hollow structure inside the fixed disk, and the second reinforcing rib is configured as a cross structure.

[0010] Preferably, the surfaces of the fixing plate, the mounting ring, and the mounting plate are all coated with a nickel-based alloy.

[0011] Preferably, heat dissipation fins are uniformly arranged on the lower surface of the fixed plate.

[0012] Preferably, multiple sets of reinforcing rods are evenly arranged inside the mounting ring.

[0013] Preferably, the upper side of the outer ring of the mounting plate is configured with a wave structure.

[0014] Preferably, the lower surface of the mounting plate has multiple sets of mounting holes evenly distributed.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting a reinforcing structure, the honeycomb structure provides high rigidity and strength per unit volume, which can effectively enhance the overall load-bearing capacity of the fixed plate, reduce deformation caused by external force or high-speed operation, and the honeycomb structure has good anti-torsion and anti-vibration performance, which can effectively disperse stress concentration, reduce fatigue damage, and extend the service life of the fixed plate.

[0017] 2. In this utility model, by setting a mounting plate with a reinforcing rod and a wave structure, the reinforcing rod increases the local and overall rigidity of the mounting ring, making it less prone to bending or deformation when subjected to external forces or high loads, thereby ensuring the operating accuracy of the mechanical equipment. The wave structure can effectively disperse stress concentration, alleviate the influence of vibration and impact, reduce the risk of fatigue damage, and extend the service life of the mounting plate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a steel-covered cast iron composite disc, including a fixed disc 1, the fixed disc 1 having a hollow structure inside, and a reinforcing structure 3 inside the hollow structure, a mounting ring 4 fixedly mounted on the fixed disc 1, a mounting disc 6 inside the mounting ring 4, a positioning hole 7 in the middle of the mounting disc 6, a fixing tooth array on the inner side of the mounting disc 6, and a fixing groove array on the outer side of the mounting disc 6.

[0029] Specifically, by fixing the fixed plate 1 in a suitable position, the hollow structure inside the fixed plate 1 not only reduces the weight, but also improves the overall strength and rigidity by strengthening the structure 3. The mounting ring 4 is connected to the fixed plate 1, so that the mounting plate 6 is firmly installed on the fixed plate 1. The positioning hole 7 in the middle of the mounting plate 6 is used for precise positioning, so that the fixed plate 1 can bear the load during operation and ensure the precise alignment of each connecting part.

[0030] Reference Figure 4 The reinforcing structure 3 includes a first reinforcing rib 301, which is fixedly disposed in the hollow structure inside the fixed disk 1, and the first reinforcing rib 301 is configured as a honeycomb structure.

[0031] Specifically, by setting the first reinforcing rib 301 and fixing it inside the hollow structure of the fixed plate 1, the honeycomb structure design can not only significantly improve the overall rigidity and strength of the fixed plate 1 while maintaining lightweight, but also evenly distribute the external load and reduce stress concentration, thereby enhancing the stability and durability of the fixed plate 1 during operation and under stress.

[0032] Reference Figure 1 The surfaces of the fixing plate 1, the mounting ring 4 and the mounting plate 6 are all coated with a nickel-based alloy.

[0033] Specifically, the nickel-based alloy coating can significantly improve the surface hardness and wear resistance of the fixed disk 1, effectively resist friction, impact and corrosion, and reduce the surface wear rate, thereby extending the service life of the fixed disk 1 and its components, and ensuring the stability and reliability of the fixed disk 1 in long-term operation.

[0034] Reference Figure 2 Heat dissipation fins 2 are evenly distributed on the lower surface of the fixed plate 1;

[0035] Specifically, the heat dissipation fins 2 can effectively increase the surface area of ​​the fixed plate 1, accelerate the heat dissipation rate, thereby reducing the temperature rise rate of the fixed plate 1 during operation, preventing the material performance from deteriorating or deforming due to overheating, and ensuring the stability and reliability of the fixed plate 1 during long-term operation.

[0036] Reference Figure 1 Multiple sets of reinforcing rods 5 are evenly arranged inside the mounting ring 4;

[0037] Specifically, the reinforcing rod 5 can enhance the overall rigidity and structural stability of the mounting ring 4, effectively distribute the load, and prevent the mounting ring 4 from deforming during operation or under stress.

[0038] Reference Figure 2 The upper outer ring of the installation disc 6 is designed with a wave structure;

[0039] Specifically, the wave structure can increase the contact area and elastic buffering capacity of the mounting plate 6, effectively disperse stress during stress or thermal expansion and contraction, reduce local stress concentration, and thus improve the overall stability and durability of the fixing plate 1.

[0040] Reference Figure 6 Multiple sets of mounting holes 8 are evenly distributed on the lower surface of the mounting plate 6;

[0041] Specifically, mounting hole 8 allows for easy and precise positioning and installation of mounting plate 6.

[0042] Example 2:

[0043] Reference Figure 5The reinforcing structure 3 includes a second reinforcing rib 302, which is fixedly installed inside the hollow structure inside the fixed disk 1. The second reinforcing rib 302 is configured as a cross structure.

[0044] Specifically, the second reinforcing rib 302 is fixedly installed inside the hollow structure of the fixed disk 1 and adopts a cross structure design. This structure can effectively disperse stress in multiple directions, improve the overall rigidity and deformation resistance of the fixed disk 1, and enhance the stability of the fixed disk 1 when subjected to torque or radial load, thereby ensuring that the fixed disk 1 is structurally stable, durable and reliable during operation.

[0045] Working principle: The fixed plate 1 is fixed in a suitable position, and then the mounting plate 6 is fixed in a suitable position through the mounting hole 8 and the positioning hole 7. The hollow structure inside the fixed plate 1 not only reduces the weight, but also improves the overall strength and rigidity through the strengthening structure 3. The nickel-based alloy coating can significantly improve the surface hardness and wear resistance of the fixed plate 1, effectively resisting friction, impact and corrosion. The heat dissipation fins 2 can effectively increase the surface area of ​​the fixed plate 1 and accelerate the heat dissipation rate, thereby reducing the temperature rise rate of the fixed plate 1 during operation.
