Description

Technical Field

[0001] This invention relates to the field of bearing processing equipment technology, specifically to a sliding bearing and its manufacturing method. Background Technology

[0002] Sliding bearings mainly include cast sliding bearings, sintered copper-based bearings, and high-strength sliding bearings. Among these, oil cooling is a crucial step in the heat treatment process of high-strength sliding bearings, decisively impacting their final performance. The cooling process not only affects the uniformity of material structure and the stability of mechanical properties but also directly influences the product's wear resistance, fatigue strength, and overall service life. If impurities in the cooling oil are not effectively separated and removed, they may gradually accumulate inside the cooling chamber, delivery pipeline, or pump body, causing a series of problems such as increased local flow resistance, uneven system pressure distribution, and temperature control imbalance. This not only reduces cooling efficiency but may also lead to unstable equipment operation, or even cause localized overheating or mechanical wear, thereby shortening the service life of the entire cooling system and increasing maintenance frequency and production costs. Existing technologies often employ simple filtration devices or periodic oil replacement, but these methods often have limited filtration effects, making it difficult to achieve efficient purification and continuous recycling of the cooling oil. Hidden dangers such as impurity deposition and oil contamination remain, affecting product quality and the long-term stable operation of equipment.

[0003] Therefore, in the heat treatment process of high-strength sliding bearings, it is not only necessary to ensure the cleanliness of the cooling oil and achieve efficient filtration and circulation purification, but also to take important technical measures to ensure product quality and long-term stable operation of equipment.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-6 As shown, the present invention is a sliding bearing, including a bearing housing 41, and further comprising; A bearing cover 42 is provided on the top of the bearing housing 41. Both ends of the top of the bearing cover 42 are slidably connected to a screw 43. A nut 44 is threadedly connected to the outer wall of the top end of the screw 43. The bottom end of the screw 43 penetrates into the interior of the bearing housing 41. A bearing bush 45 is embedded in the inner wall of the top end of the bearing housing 41.

[0026] An apparatus for manufacturing a sliding bearing includes a cooling box 1, and further includes: A separation mechanism is provided on the cooling tank 1. The separation mechanism includes a filter box 101 provided on the cooling tank 1. The separation mechanism is used to filter and remove impurities in the cooling oil. The circulation mechanism is installed inside the cooling box 1. The circulation mechanism includes a circulation chamber 2 installed on the cooling box 1. The circulation mechanism is used to reduce the waste of cooling oil by circulating cooling during the cooling of the bearing.

[0027] The separation mechanism includes a filter box 101 fixedly installed on the right side of the cooling box 1. A conical plate 102 is fixedly installed inside the filter box 101. A baffle plate 103 is provided on the top of the conical plate 102. Several filter holes 104 are opened on the inner wall of the conical plate 102. A circular box 105 is fixedly installed at the bottom of the conical plate 102. A circulation pipe 106 is fixedly installed on the outer wall of the circular box 105.

[0028] The above scheme is adopted: During the cooling process, the cooling oil entering the cooling chamber 201 will flow through the oil drain plate 111 and enter the conical plate 102. During the flow, the cooling oil will be initially filtered through the filter holes 104 set on the conical plate 102. Impurities will be trapped inside the conical plate 102, and the purified cooling oil will flow into the circular box 105 and then flow back to the circulation chamber 2 to realize the continuous recycling of the cooling medium. At the same time, it will improve the cleaning efficiency of the cooling system.

[0029] A rotating rod 107 is rotatably mounted through the conical plate 102. Several centrifugal plates 108 are fixedly mounted on the outer wall of the rotating rod 107. A first gear 109 is fixedly mounted at the bottom end of the rotating rod 107. The rotating rod 107 rotates through the circular box 105. A discharge plate 110 is fixedly mounted on the bottom inner wall of the conical plate 102. The top end of the discharge plate 110 extends to the outside of the filter box 101. An oil drain plate 111 is fixedly mounted on the right side of the cooling box 1.

[0030] The conical plate 102 has a hollow conical structure, with its larger top end connected to the inner wall of the filter box 101 and its smaller bottom end connected to the circular box 105, forming a funnel-shaped arrangement. A ring-shaped or disc-shaped baffle plate 103 is provided at the top of the conical plate 102 to guide the cooling oil to flow evenly along the inner wall of the conical plate, preventing impurities from falling directly. Multiple filter holes 104 are evenly distributed on the inner wall of the conical plate 102. During the flow of the cooling oil, preliminary filtration is achieved through the filter holes 104, trapping larger particles of impurities inside the conical plate. This structure effectively improves the preliminary filtration efficiency of the cooling oil, prevents impurities from entering the subsequent circulation system, ensures smooth oil flow, and enhances the stability and cooling effect of the cooling system.

[0031] The above-mentioned scheme transmits power to the rotating rod 107, causing it to rotate synchronously. The rotating rod 107 drives multiple centrifugal plates 108 to rotate synchronously, forming a high-speed rotating assembly. The rotation of the centrifugal plates 108 causes impurities retained in the conical plate 102 to be affected by centrifugal force and move away from the center of rotation. When the impurities collide with the inclined surface of the discharge plate 110, they are thrown out of the device under the guidance of the inclined surface, thereby achieving efficient separation and automatic removal of impurities in the cooling oil. This structure, through the combination of mechanical transmission and centrifugal separation technology, effectively improves the cleanliness of the cooling oil and extends the service life of the equipment without affecting the normal operation of the cooling system, while reducing the maintenance frequency. It has good practicality and automated processing capabilities.

[0032] like Figures 1-6 As shown, the circulation mechanism includes a circulation chamber 2 and a cooling chamber 201 opened in the cooling box 1. A closing door 202 is hinged to the top of the cooling box 1. An oil supply pipe 203 is fixedly installed on the left side of the cooling box 1. The oil supply pipe 203 communicates with the cooling chamber 201 and the circulation chamber 2. The top end of the circulation pipe 106 communicates with the circulation chamber 2. The oil drain plate 111 communicates with the cooling chamber 201.

[0033] The above solution involves: first, opening the closed door 202 and placing the bearing to be cooled stably in the designated position within the cooling chamber 201. After confirming that the placement is correct, closing the closed door 202 ensures that the cooling chamber is in a relatively sealed state. This operation not only effectively prevents external impurities from entering the cooling chamber and contaminating the cooling oil, but also avoids the cooling oil from splashing out due to flow or vibration during the cooling process, thereby ensuring the safety of equipment operation and the cleanliness of the working environment. At the same time, good sealing also helps to improve cooling efficiency, enabling the bearing to obtain a more uniform and efficient cooling effect.

[0034] A drive motor 204 is fixedly installed on the left side of the cooling box 1. A reciprocating screw 205 is fixedly installed on the output shaft of the drive motor 204. The right end of the reciprocating screw 205 rotates through the cooling box 1 and extends into the filter box 101. A second gear 206 is fixedly installed on the right end of the reciprocating screw 205. The second gear 206 meshes with the first gear 109.

[0035] The system is equipped with a drive motor 204. After starting, the drive motor 204 drives the reciprocating screw 205 to rotate, which in turn drives the second gear 206 meshing with it to rotate synchronously. The second gear 206 meshes with the first gear 109.

[0036] The reciprocating screw 205 is threaded with an internal thread plate 207. Two rectangular slots 208 are opened in the internal thread plate 207. Several through holes 209 are opened on the right side of the rotating rod 107. T-shaped hollow plates 210 are slidably installed in the two rectangular slots 208 respectively. The left sides of the two T-shaped hollow plates 210 extend out of the two rectangular slots 208 respectively.

[0037] During the cooling process of the bearing, the rotation of the reciprocating screw 205 will drive the internal thread plate 207 that it mates with to move back and forth in the horizontal direction. When the internal thread plate 207 moves towards the drive motor 204, the cooling oil on its left side is squeezed. Under the influence of oil resistance, the T-shaped hollow plate 210 will slide into the rectangular groove 208 and undergo compression deformation during this process. At this time, the compressed cooling oil is forced into the cooling chamber 201 through the oil supply pipe 203, further pushing the cooling oil to flow through the oil drain plate 111, the conical plate 102, the circular box 105 and the circulation pipe 106 in sequence, and finally re-enter the circulation chamber 2 and converge to the left side area of ​​the internal thread plate 207 to form a complete cooling circulation path.

[0038] Limiting springs 212 are fixedly installed on the right side of the two cooling chambers 201 respectively. The right ends of the two T-shaped hollow plates 210 are fixedly connected to the two rectangular grooves 208 respectively. The inner walls of the front and back sides of the two T-shaped hollow plates 210 are respectively provided with strip grooves 211.

[0039] The above scheme is adopted: when the internal thread plate 207 begins to move back away from the drive motor 204, due to the combined action of the flow resistance of the cooling oil and the restoring force provided by the limit spring 212, the T-shaped hollow plate 210 will move back away from the rectangular groove 208. At this time, the strip groove 211 set on the T-shaped hollow plate separates from the rectangular groove 208, so that the oil circuit in the circulation chamber 2 is interconnected, thereby realizing the balance of the oil in the chamber and the stability of the liquid level. This structure realizes the orderly flow of cooling oil in different working stages through the combination of mechanical transmission and hydraulic control. It not only improves the cooling efficiency, but also enhances the responsiveness and stability of the system. It is suitable for efficient and controllable circulating cooling of key components such as bearings.

[0040] Working principle and usage process of this invention: During the cooling process of the bearing, the rotation of the reciprocating screw 205 drives the mating internal thread plate 207 to move back and forth horizontally. When the internal thread plate 207 moves closer to the drive motor 204, the cooling oil on its left side is compressed. Under the influence of oil resistance, the T-shaped hollow plate 210 slides into the rectangular groove 208 and undergoes compression deformation during this process. At this time, the compressed cooling oil is forced into the cooling chamber 201 through the oil supply pipe 203, further pushing the cooling oil to flow sequentially through the oil drain plate 111, the conical plate 102, the circular box 105, and the circulation pipe 106, and finally re-enters the circulation chamber 2 and converges to the left side of the internal thread plate 207, forming a complete cooling system. However, in the circulation path, when the internal thread plate 207 begins to move back away from the drive motor 204, due to the combined action of the flow resistance of the cooling oil and the restoring force provided by the limit spring 212, the T-shaped hollow plate 210 will move back away from the rectangular groove 208. At this time, the strip groove 211 set on the T-shaped hollow plate separates from the rectangular groove 208, so that the oil circuit in the circulation chamber 2 is interconnected, thereby realizing the balance of the oil in the chamber and the stability of the liquid level. This structure realizes the orderly flow of cooling oil in different working stages through the combination of mechanical transmission and hydraulic control, which not only improves the cooling efficiency, but also enhances the responsiveness and stability of the system. It is suitable for efficient and controllable circulation cooling of key components such as bearings. During the cooling process, the cooling oil entering the cooling chamber 201 flows sequentially through the drain plate 111 and into the conical plate 102. As the oil flows, it undergoes preliminary filtration through the filter holes 104 on the conical plate 102, trapping impurities inside. The purified oil then flows into the circular box 105 and from there back into the circulation chamber 2, achieving continuous recycling of the cooling medium. Simultaneously, to improve the cleaning efficiency of the cooling system, a drive motor 204 is installed. Upon startup, the drive motor 204 drives the reciprocating screw 205 to rotate, which in turn drives the second gear 206 meshing with it to rotate synchronously. The second gear 206 meshes with the first gear 109, thereby driving the moving... The force is transmitted to the rotating rod 107, causing it to rotate synchronously. The rotating rod 107 drives multiple centrifugal plates 108 to rotate synchronously, forming a high-speed rotating assembly. The rotation of the centrifugal plates 108 causes impurities retained in the conical plate 102 to be affected by centrifugal force and move away from the center of rotation. When the impurities collide with the inclined surface of the discharge plate 110, they are thrown out of the device under the guidance of the inclined surface, thereby achieving efficient separation and automatic removal of impurities in the cooling oil. This structure, by combining mechanical transmission and centrifugal separation technology, effectively improves the cleanliness of the cooling oil and extends the service life of the equipment without affecting the normal operation of the cooling system, while reducing the maintenance frequency. It has good practicality and automation capabilities.

[0041] This patented oil-cooling process for sliding bearings utilizes a highly efficient circulating filtration system. By immersing the high-temperature bearing workpiece in clean cooling oil, the rapid heat exchange capacity of the oil achieves rapid cooling of the bearing. During circulation, the cooling oil undergoes multi-stage filtration and centrifugal separation, effectively removing impurities and ensuring the cleanliness and fluidity of the oil. This process not only improves the hardness and wear resistance of the bearing material but also ensures the uniformity of the structure and the stability of mechanical properties, significantly enhancing product quality and equipment reliability.

[0042] Meanwhile, in this patented oil-cooling process, anti-wear agents and hardening accelerators are added to the cooling oil. During heat exchange, these agents penetrate to the surface of the bearing workpiece, further enhancing the surface hardness and wear resistance of the material. Using this process, a protective film with good density and enhanced lubricity can be formed on the bearing surface, which not only strengthens the bearing's wear resistance but also improves its tribological properties and extends its service life.

[0043] The present invention has the following beneficial effects: (1) In the cooling process of this invention, the cooling oil entering the cooling chamber first flows into the conical plate (102) through the oil drain plate (111). At this stage, the cooling oil undergoes preliminary filtration through the filter holes (104) set on the conical plate (102). The impurities contained therein are trapped in the conical plate (102), and the purified cooling oil flows into the subsequent circular box (105) and then flows back to the circulation chamber (2) to realize the continuous circulation of the cooling medium. At the same time, after the drive motor (204) is started, its output shaft drives the reciprocating screw (205) to rotate, which in turn drives the second gear (206) meshing with it to rotate synchronously. The second gear (206) meshes with the first gear (109) and transmits power to the rotating rod (107) to rotate accordingly. The rotating rod (107) drives several centrifugal plates (108) to rotate synchronously at high speed. During this process, impurities within the conical plate (102) are subjected to centrifugal force and move away from the center of rotation. When the impurities collide with the inclined surface of the discharge plate (110), they are guided by the inclined surface and smoothly thrown out of the device, thereby achieving automatic separation and efficient removal of impurities in the cooling oil. This mechanism can effectively maintain the cleanliness and good fluidity of the cooling oil without affecting the normal operation of the system, preventing a decrease in cooling efficiency due to impurity accumulation. Through the combined application of the above structural design and working principle, not only is the stability and self-cleaning ability of the cooling system significantly improved, but the uniformity and efficiency of the cooling process are also further guaranteed, enabling the workpiece to be cooled more quickly and uniformly, thereby improving the overall processing quality and equipment operational reliability.

[0044] (2) In the process of cooling the bearing, the rotation of the reciprocating screw (205) will drive the internal thread plate (207) that it cooperates with to move back and forth in the horizontal direction. When the internal thread plate (207) moves towards the drive motor (204), the cooling oil on its left side is squeezed. Under the influence of hydraulic resistance, the T-shaped hollow plate (210) will slide into the rectangular groove (208) and undergo elastic compression deformation during this process. At this time, the pressurized cooling oil is transported to the cooling chamber (201) through the oil supply pipe (203) and further flows through the oil drain plate (111), the conical plate (102), the circular box (105) and the circulation pipe (106) in sequence, and finally re-enters the circulation chamber (2) and converges to the left side of the internal thread plate (207) to realize the continuous circulation of the cooling medium. When the internal thread plate (207) begins to move away from the drive motor (204), under the combined action of the flow resistance of the cooling oil and the reset force provided by the limiting spring (212), the T-shaped hollow plate (210) will move back away from the rectangular groove (208). At this time, the strip groove (211) set on the T-shaped hollow plate (210) disengages from the rectangular groove (208), making the oil passages in the circulation chamber (2) interconnected, thereby promoting the cooling oil level in the chamber to become uniform and maintaining the system pressure balance. Through the reasonable layout design of components such as the drain plate (111), the conical plate (102), the circular box (105), and the circulation pipe (106), not only is the uniform distribution performance of the cooling oil in the whole system improved, but the stability and continuity of the cooling process are also effectively enhanced, ensuring that all parts of the workpiece can obtain a consistent and good cooling effect, thereby improving the overall processing quality and the reliability of equipment operation.
