[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.
[0025] In this document, "illustrative" means "serving as an example, illustration, or description," and any illustrations or embodiments described herein as "illustrative" should not be construed as a more preferred or advantageous technical solution. For the sake of brevity, each figure only schematically shows the parts relevant to this exemplary embodiment, and they do not represent the actual structure or true proportions of the product.
[0026] The bearing water jacket in this invention is a bearing cooling and lubrication system designed for high-temperature operating parts in composite material equipment, such as thermoplastic prepreg machines and hot presses. The operating temperature of this equipment is generally between 150℃ and 450℃. Under high-temperature, continuous operation conditions, bearings are prone to overheating and deformation, leading to bearing damage. Adding a water jacket effectively reduces the temperature of the bearings and shafts, ensuring the stability of equipment operation.
[0027] Currently tested shaft systems with spans of 300–2000 mm demonstrate stable cooling capabilities. For large rollers, double or multiple water jackets can be used for uniform cooling. The cooling medium is circulating cooling water, with the chiller set to a temperature not exceeding 30°C; the operating temperature range is 150–450°C; and the lubricating medium is high-temperature resistant grease or high-temperature synthetic grease. In practical applications, when the roller surface heating zone reaches 450 degrees Celsius, the distance between the roller surface and the bearing does not exceed 30cm, and the temperature remains below 80 degrees Celsius after passing through the cooling water jacket. This is considered instantaneous cooling.
[0028] One aspect of this utility model is as follows: Figure 1 As shown, a plate bearing water jacket is provided, which includes: One aspect of this utility model is, as follows Figure 1 As shown, a plate bearing water jacket is provided, which is implemented on the rotating shaft of a high-temperature steel wheel. Figure 1 As shown, the plate bearing water jacket includes: a cooling valve body 10, the main body of which includes a thickness direction. A recess 11 is formed, the depth of which is greater than the radius of the rotating shaft. A first semi-circular arc surface 12 is formed within the recess 11. The first semi-circular arc surface 12 is parallel to the thickness direction.
[0029] like Figure 2 , 3 As shown, a first cooling channel 91 and a second cooling channel 92 are formed in the cooling valve body 10 around the recess 11 and the first semi-circular surface 12, and are interconnected. The extending directions of the first cooling channel 91 and the second cooling channel 92 are parallel to each other. The two ends of the first cooling channel 91 and the second cooling channel 92 in their extending directions are located at the two ends of the recess 11, respectively.
[0030] like Figure 2 , 3 As shown in Figures 4 and 5, one or more first lubricating oil holes 13 are formed between the first cooling channel 91 and the second cooling channel 92. The first lubricating oil holes 13 connect the outer surface of the cooling valve body 10 and the first semi-circular arc surface 12.
[0031] like Figure 6 , 7 As shown, an assembly 20 forms a second semicircular arc surface 21. The second semicircular arc surface 21 faces the first semicircular arc surface 12. The assembly 20 is detachable, for example, bolted to a recess 11, so that the second semicircular arc surface 21 and the first semicircular arc surface 12 can be fitted onto the outer circumferential surface of a rotating shaft. One or more second lubricating oil holes 22 are formed on the assembly 20. The second lubricating oil holes 22 communicate with the outer surface of the assembly 20 and the second semicircular arc surface 21.
[0032] The structural advantages of mounting the fitting 20 on the cooling valve body 10 are that it facilitates the inspection and maintenance of worn areas during assembly and disassembly, while ensuring precise alignment of the lubrication channels, improving overall heat dissipation and lubrication efficiency, and extending bearing life. The structural design balances manufacturability and functional reliability, embodying a unity of engineering practicality and innovation. The second lubrication hole 22 and the first lubrication hole 13 are at least partially aligned along the thickness direction in the assembled state to form a continuous lubrication path, ensuring uniform distribution of lubricating oil in the semi-circular contact area. The mating interface between the cooling valve body 10 and the fitting 20 is equipped with a sealing structure to prevent cooling medium leakage. This plate bearing water jacket, through a synergistic cooling and lubrication mechanism, effectively reduces thermal stress and frictional loss of the rotating shaft under high-temperature conditions, making it suitable for stable operation under heavy loads and high speeds. The symmetrical arrangement of the cooling channels enhances the uniformity of cooling medium flow and avoids localized overheating. The inlet and outlet ports at both ends of the recess facilitate quick connection to external pipelines, improving maintenance efficiency.
[0033] Both the first and second semi-circular arc surfaces undergo surface hardening treatment to improve wear resistance and anti-galling capabilities. The stress distribution of the entire water jacket structure is optimized through finite element analysis to ensure structural stability under high-temperature variable load conditions and meet the requirements for long-term continuous operation. After the second semi-circular arc surface 21 of the assembly 20 and the first semi-circular arc surface 12 of the cooling valve body 10 are aligned and positioned, axial clamping is achieved through pre-tightening bolts to ensure precise alignment and reliable sealing of the lubrication holes. The first and second bearing bushes are made of bronze or stainless steel, and their inner surfaces undergo surface hardening treatment.
[0034] The plate bearing water jacket proposed in this invention effectively solves the problems in the prior art through its unique structure. This plate bearing water jacket not only achieves an optimized layout of cooling channels and lubrication holes in its design, but also improves the convenience of maintenance and the flexibility of component replacement through its detachable assembly design. This design is particularly suitable for industrial environments with high requirements for equipment operational stability and maintenance efficiency.
[0035] Furthermore, this utility model's plate bearing water jacket system, through an integrated design approach, combines cooling and lubrication functions, reducing system complexity and floor space while improving overall operational reliability and energy efficiency. This is of great significance for enhancing the overall performance of mechanical equipment, extending its service life, and reducing operating costs.
[0036] In one embodiment of the plate bearing water jacket of this utility model, the cooling valve body 10 includes a top surface. A recess 11 is formed on the top surface.
[0037] like Figure 2As shown, the first cooling channel 91 and the second cooling channel 92 are located at both ends of the cooling valve body 10 at both ends of the recess 11 in the extending direction.
[0038] like Figure 4 As shown, the plate bearing water jacket also includes an inlet connector 31 and an outlet connector 32. The inlet connector 31 and the outlet connector 32 are respectively connected to the first cooling channel 91 and the second cooling channel 92 from their respective ends. The inlet connector 31 and the outlet connector 32 extend from opposite sides of the cooling valve body 10 and are parallel to the top surface.
[0039] like Figure 2 , 3 As shown, in one embodiment of the plate bearing water jacket of this utility model, the first cooling channel 91 or the second cooling channel 92 includes: like Figure 2 , 3 As shown, pipes 93 and 94 on both sides are respectively located within the cooling valve bodies 10 on both sides of the recess 11. The extension direction of the pipes on both sides is perpendicular to the top surface. A bottom pipe 95 is located within the cooling valve body 10 adjacent to the first semi-circular surface 12. The extension direction of the bottom pipe 95 is perpendicular to the pipes on both sides. This forms a U-shaped cooling flow channel, allowing coolant to flow in from the inlet connector 31, enter the bottom pipe 95 through one side pipe 93, and then flow out through the other side pipe 94 to the outlet connector 32, achieving effective cooling of the area near the first semi-circular surface 12. This structural layout is reasonable, improving heat exchange efficiency while avoiding cross-interference of cooling channels, ensuring stable system operation.
[0040] By precisely controlling the coolant flow path and lubrication distribution, this design achieves synergistic optimization of centralized cooling and dynamic lubrication in hot zones. The U-shaped flow channel reduces fluid resistance and improves heat dissipation response speed. Combined with the continuous oil supply to the friction interface through the second lubrication hole, wear is significantly reduced. The overall structure ensures stability during high-intensity operation while reflecting a profound consideration for energy efficiency and sustainable operation, providing an innovative solution for protecting core components under complex working conditions. This plate bearing water jacket demonstrates excellent adaptability in practical applications, effectively coping with harsh conditions such as frequent start-stop cycles, load fluctuations, and high-temperature environments. Its modular structure facilitates installation and replacement, significantly reducing downtime for maintenance and improving production line efficiency. Simultaneously, material selection considers both corrosion resistance and thermal conductivity, ensuring cooling stability during long-term operation.
[0041] like Figure 2 , 3 As shown, the pipes on both sides and the bottom pipe 95 of the first cooling channel 91 are parallel to the pipes on both sides and the bottom pipe 95 of the second cooling channel 92, respectively.
[0042] like Figure 4As shown, in one embodiment of the plate bearing water jacket of this utility model, a plurality of first lubricating oil holes 13 are located between the bottom pipe 95 of the first cooling channel 91 and the bottom pipe 95 of the second cooling channel 92 and are arranged along the circumferential extension direction of the first semi-circular arc surface 12. A plurality of second lubricating oil holes 22 are arranged along the axial extension direction of the first semi-circular arc surface 12.
[0043] like Figure 4 , 5 As shown, in another embodiment of the plate bearing water jacket of this utility model, it includes: a first bearing bush 41. It is mounted on the first semi-circular arc surface 12 of the cooling valve body 10. The inner surface of the first bearing bush 41 is parallel to the first semi-circular arc surface 12. A first lubrication groove 42 is formed circumferentially along the inner surface of the first bearing bush 41. Multiple through holes are formed at positions corresponding to the openings of the multiple first lubrication oil holes 13 in the first lubrication groove 42.
[0044] like Figure 4 , 7 As shown, in one embodiment of the plate bearing water jacket of this utility model, it includes: a second bearing bush 43. It is mounted on the second semi-circular arc surface 21 of the assembly 20. The inner surface of the second bearing bush 43 is parallel to the second semi-circular arc surface 21. A second lubrication groove 44 is formed circumferentially along the inner surface of the second bearing bush 43. Multiple through holes are formed at positions corresponding to the openings of the multiple second lubrication oil holes 22 in the second lubrication groove 44.
[0045] Therefore, the design of the first lubrication groove 42 and the second lubrication groove 44 effectively improves the lubrication performance and heat dissipation efficiency of the plate bearing water jacket under dynamic loads, and significantly extends the bearing service life, especially under high temperature and high load conditions. Simulation verification shows that the spiral distribution structure of the lubrication grooves promotes the formation of a dynamic pressure field for the lubricating oil, enhances the oil film carrying capacity, and the flow guiding design at the edge of the grooves improves the circulation efficiency of the cooling oil, effectively reducing the interface temperature of the friction pair.
[0046] Furthermore, the first lubrication groove 42 and the second lubrication groove 44 are positioned on opposite sides of the rotating shaft, ensuring that the lubricating medium is continuously guided to the friction interface under centrifugal force, further enhancing the uniformity and stability of lubrication distribution. This symmetrical arrangement effectively balances the hydrodynamic field during rotation, preventing local oil film breakage and improving the overall operational reliability of the water jacket. Simultaneously, this structural design considers manufacturing feasibility, ensuring easy molding during precision machining without requiring additional assembly steps. Through multiple sets of comparative experiments, the plate bearing water jacket using this structure maintained good lubrication after continuous operation, without significant wear or overheating, verifying its long-term stability and effectiveness. Another aspect of this utility model also provides a plate bearing water jacket system. This is a cooling system including the plate bearing water jacket of this utility model.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
