[0001] The present application relates to the technical field of extruder gearbox, and in particular to an extruder gearbox and an extruder gearbox. BACKGROUND

[0002] The extruder gearbox is one of the most core components of a single-screw or double-screw extruder, which is located between the motor and the extruder screw. The motor usually operates at a high speed, but the extruder screw needs to work at a very low speed, and at the same time needs a huge torque to shear, melt and push the high-viscosity plastic melt. The extruder gearbox can reduce the high speed of the motor to the working speed required by the screw, and amplify the torque by tens or even hundreds of times in the process, thereby meeting the power requirements of the extruder.

[0003] At present, the existing extruder gearbox structure is usually a cuboid, which lacks effective open design, resulting in poor heat dissipation efficiency of the transmission components. SUMMARY

[0037] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0038] ​​​The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the front and rear associated objects are in an "or" relationship.

[0039] The inventor found in the research of the extruder gearbox that the existing extruder gearbox structure usually adopts a closed, integral cuboid box structure, as shown in Figure 10 In terms of heat dissipation, this closed cuboid structure completely encloses the high-speed rotating transmission components such as gears and bearings, forming a relatively closed space. A large amount of friction heat is generated during the meshing transmission of the gears. Due to the limited internal space of the box and the poor exchange with the outside air, the heat is difficult to dissipate quickly, and is easy to accumulate in the box, causing the temperature of the lubricating oil to continue to rise. The rise in oil temperature reduces the viscosity and lubrication performance of the lubricating oil, accelerating its oxidation and deterioration, which not only aggravates the wear of the gears and bearings and shortens their service life, but also may cause the clearance between the parts to change due to thermal expansion, affecting the transmission accuracy, and even in extreme cases, causing the equipment to overheat and stop, affecting the continuity and stability of production.

[0040] The transmission structure of the existing extruder gearbox usually adopts a multi-stage gear pair in series layout, and the heat dissipation measures (such as heat dissipation fins or fans on the outer surface of the box) mainly act on the outermost wall of the box. However, in this centralized structure with layer-by-layer transmission, the heat generated by the gears and bearings located in the middle and core of the transmission chain must pass through other components and the heat conduction of the lubricating oil before finally reaching the outer wall of the box to be dissipated. This long heat transfer path results in a large thermal resistance, making it difficult for the heat of the core transmission components to be efficiently conducted out, thereby forming a condition where the internal temperature of the box is much higher than the external temperature, causing the heat dissipation effect of the internal key transmission components to be much worse than that of the outer components, becoming a weak link in the overall system heat management.

[0041] The extruder gearbox box 100 and the extruder gearbox 200 provided by the present application will be described in detail below in combination with the accompanying Figures 1 to 9 , through specific embodiments and application scenarios.

[0042] Some embodiments of the present application disclose an extruder gearbox box 200, comprising a mounting box 110 and a heat conduction assembly 120, the mounting box 110 being used for mounting transmission components 210.

[0043] As shown in Figure 1 and Figure 5 , the mounting box 110 is provided with a gap 150, which penetrates through both sides of the mounting box 110 along the width direction of the mounting box 110, and also penetrates through both sides of the mounting box 110 along the height direction of the mounting box 110. By providing a gap 150 that penetrates through the mounting box 110 along both the width and height directions, the center region of the overall box in the prior art, which was originally hidden and had the largest thermal resistance, is directly exposed to the external environment, thereby increasing the effective contact area between the mounting box 110 and the external air and enhancing the heat dissipation effect of the mounting box 110. Moreover, the position of the gap 150 of the mounting box 110 is exactly at the position where the heat generated by the transmission component 210 is most concentrated and the heat dissipation demand is most urgent, greatly shortening the heat transfer path and effectively avoiding the accumulation of heat in the middle of the transmission chain, thereby significantly reducing the peak operating temperature of the transmission component 210 under high-speed heavy-load working conditions and improving the thermal balance performance and operation reliability of the entire extruder gearbox 200.

[0044] In this embodiment, the width direction of the mounting box 110 is as shown by W in Figure 1 , and the height direction of the mounting box 110 is as shown by H in Figure 1 .

[0045] As shown in Figure 4 and Figure 5 , the mounting box 110 is provided with a connecting portion 130 corresponding to the gap 150, and part of the transmission component 210 is located in the connecting portion 130. The gear portion of the transmission component 210 is accommodated inside the mounting box 110, ensuring good sealing and support, and the main shaft portion of the transmission component 210 extends into the mounting box 110 through the connecting portion 130, which supports the main shaft portion of the transmission component 210, and the outer surface of the connecting portion 130 is also directly exposed to the external environment, so that the heat generated in the connecting portion 130 area can be directly and quickly dissipated to the outside, avoiding the large backflow and accumulation of heat into the inside of the mounting box 110 on both sides, and significantly improving the thermal management efficiency and operation reliability of the entire transmission system.

[0046] As shown in Figure 1 and Figure 4As shown, the heat conduction assembly 120 is arranged in the gap 150 and connected with the two opposite walls of the gap 150 corresponding to the mounting box 110, for transmitting the heat of the mounting box 110 to the outside. By arranging the heat conduction assembly 120 between the gap 150 of the mounting box 110, the large amount of friction heat generated inside the mounting box 110 can be actively captured and conducted to the outside environment, significantly accelerating the heat loss, effectively controlling the working temperature of the lubricating oil, delaying its oxidation, and achieving the purpose of active heat dissipation. Moreover, the arrangement of the heat conduction assembly 120 can accurately address the bottleneck problem of poor heat dissipation of the internal transmission component 210, ensuring that the temperature of the gears, main shafts, bearings and other structures of the transmission component 210 is not too high, thereby greatly improving the transmission efficiency, service life and operation reliability of the entire extruder gear box 200.

[0047] As shown in Figure 7 , the heat conduction assembly 120 includes two heat conduction bottom plates 121 and a plurality of fins 122. The two heat conduction bottom plates 121 are respectively arranged on the two opposite walls of the gap 150 corresponding to the mounting box 110. The plurality of fins 122 are arranged equidistantly and connected with the two heat conduction bottom plates 121 respectively. The heat conduction assembly 120 efficiently absorbs the heat generated during the operation of the box body and the internal transmission component 210 by attaching the heat conduction bottom plates 121 to the opposite faces of the gap 150 of the mounting box 110. Then, the heat is rapidly conducted to the equidistantly arranged large number of fins 122. These fins 122 greatly increase the contact area with air, and through the natural convection or forced flow of air, the captured heat is continuously and quickly dissipated to the outside environment, achieving the purpose of efficient heat dissipation. The design of the heat conduction bottom plates 121 and the fins 122 maximizes the heat dissipation area and accurately targets the main heat source for directional heat dissipation, effectively controlling the temperature inside the mounting box 110 and solving the problem of poor heat dissipation of the internal transmission component 210.

[0048] In the present embodiment, as shown in Figure 7 , the two ends of the heat conduction bottom plate 121 are flush with the end face of the mounting box 110. The flush structure of the heat conduction bottom plate 121 with the end face of the mounting box 110 maximizes the contact area between the heat conduction bottom plate 121 and the mounting box 110, ensuring that the heat inside the mounting box 110 can be efficiently transmitted to the heat conduction bottom plate 121 through the entire end face without obstruction, avoiding the heat flow bottleneck caused by steps or protrusions. At the same time, the flush structure makes the overall appearance more regular, reduces the stress concentration points that may be caused by protrusions 1211 or recesses, not only improves the structural strength, but also facilitates the installation layout in limited space, preventing interference with surrounding components.

[0049] In the present embodiment, as shown in Figure 7As shown, the two ends of the fins 122 are flush with the end faces of the heat-conductive base plate 121. The two ends of the fins 122 being flush with the end faces of the heat-conductive base plate 121 makes the effective heat dissipation surface of all the fins 122 fully exposed to the airflow without any part being wasted or shielded, thus providing the ultimate heat dissipation area under given spatial constraints. In addition, the flush design eliminates the protruding edges of the fins 122, significantly reducing the risk of the fins 122 being bent or damaged due to accidental impact during transportation, installation or maintenance, and improving the structural rigidity and long-term reliability of the entire heat-conductive assembly 120.

[0050] As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 7 As shown, the heat-conductive assembly 120 further comprises at least one fan 123 arranged on one side of the heat-conductive base plate 121. By adding the fan 123 on one side of the heat-conductive base plate 121, an active forced convection is introduced to the original passive heat dissipation system, greatly improving the heat dissipation effect of the entire heat-conductive assembly 120. The directional airflow generated by the fan 123 can instantly blow away the hot air accumulated on the surface of the fins 122 and continuously bring in fresh low-temperature air, thus significantly accelerating the heat exchange rate between the fins 122 and the air. As a result, the heat extracted from the mounting box 110 by the heat-conductive base plate 121 can be more efficiently taken away, forming a strong suction effect and achieving active cooling of the core heat source. This improvement is particularly suitable for high-load or high-temperature working conditions, and can quickly control the temperature rise of the transmission components 210, ensuring the continuous operation of the extruder gearbox 200 in a more stable and safer thermal environment.

[0051] As a preferred embodiment of the present application, the heat-conductive assembly 120 is two, arranged on opposite sides of the heat-conductive base plate 121.

[0052] As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 1 As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 4 As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200.

[0053] As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 5 As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 6 As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 7 As shown in FIG. 1, the heat-conductive assembly 120 is arranged on the top of the mounting box 110. The heat-conductive assembly 120 is arranged on the top of the mounting box 110 to effectively dissipate the heat generated by the transmission components 210, and to ensure the stable and reliable operation of the extruder gearbox 200. Figure 8As shown, the heat conduction assembly 120 is detachably connected with the mounting box 110. The heat conduction assembly 120 and the mounting box 110 are designed in a detachable connection manner, which greatly improves the maintainability and flexibility of the heat conduction assembly 120. This connection manner allows the heat conduction assembly 120 to be quickly detached, cleaned or replaced as an independent module at any time without affecting the main structure of the mounting box 110. This not only can completely remove the dust and oil accumulated between the fins 122 for a long time to restore the best heat dissipation performance, but also can replace only the heat conduction assembly 120 when the heat conduction assembly 120 is damaged accidentally or needs to be upgraded according to the working condition, without scrapping or overall processing the heavy mounting box 110, thereby significantly reducing the maintenance cost, shortening the downtime, and giving the entire system strong adaptability and extensibility. Moreover, the heat conduction assembly 120 can be used flexibly according to the heat dissipation requirements, for example, in the case that the extruder gear box 200 needs to be quickly heated by lubricating oil, the heat conduction assembly 120 is removed, and the heat conduction assembly 120 is installed when the extruder gear box 200 is overloaded.

[0054] As shown in Figure 6 and Figure 8 As shown, one of the mounting box 110 and the heat conduction bottom plate 121 is provided with a clamping groove 1101, and the other is provided with a protrusion 1211 matched with the clamping groove 1101. The mounting box 110 and the heat conduction bottom plate 121 are connected through the matching of the clamping groove 1101 and the protrusion 1211, realizing the quick and accurate positioning and stable connection between them. This design can play the role of self-guiding and centering during assembly, ensuring that the heat conduction bottom plate 121 is tightly attached to the heating wall surface of the mounting box 110, and the contact thermal resistance is minimized, thereby ensuring efficient heat conduction. At the same time, this buckle 1212 type connection without bolts simplifies the assembly and disassembly process, and the quick assembly and disassembly of the heat conduction assembly 120 can be completed without special tools, greatly improving the operation efficiency of daily cleaning and maintenance, inspection or replacement of the heat dissipation module.

[0055] In some embodiments, the clamping groove 1101 is provided on the mounting box 110, and the protrusion 1211 is provided on the heat conduction bottom plate.

[0056] In some embodiments, the clamping groove 1101 is provided on the heat conduction bottom plate, and the protrusion 1211 is provided on the mounting box 110.

[0057] As preferred in the embodiment, the card slot 1101 is a dovetail slot, and the protrusion 1211 is a trapezoidal tenon. The dovetail slot and the trapezoidal tenon are matched to achieve the connection between the heat-conducting bottom plate 121 and the mounting box 110, which has high-precision positioning, great tensile strength, and excellent stability. The trapezoidal inclined surface structure of the dovetail slot can produce a strong mechanical self-locking effect after insertion and matching, effectively resisting loosening and separation caused by vibration and thermal expansion and contraction, ensuring that the heat-conducting bottom plate 121 and the box wall maintain close contact during long-term use, thereby maintaining extremely low thermal resistance. At the same time, this large-area mortise and tenon matching also provides excellent structural rigidity and a larger heat conduction contact area, enabling heat to be more uniformly and efficiently conducted from the mounting box 110 to the entire heat-conducting assembly 120, significantly improving the reliability and heat dissipation efficiency of the connection.

[0058] As shown in Figure 8 , the end faces of the two heat-conducting bottom plates 121 are respectively provided with a plurality of buckles 1212 for fixing the fan 123. The design of arranging multiple buckles 1212 on the end face of the heat-conducting bottom plate 121 to fix the fan 123 eliminates the need for threaded holes on the heat-conducting bottom plate 121 or the fan 123, and also eliminates the cumbersome steps of screw fastening. Through the elastic locking structure of the buckle 1212, the fan 123 can be accurately positioned and firmly fixed at the optimal heat dissipation position. This not only greatly simplifies the assembly and daily maintenance (such as cleaning or replacing the fan 123) process, improving efficiency, but also ensures the connection rigidity of the fan 123 and the heat-conducting assembly, effectively resisting vibration and preventing it from loosening during operation, thereby ensuring the long-term stable working performance of the active heat dissipation system.

[0059] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the mounting box 110 includes an upper box body 111 and a lower box body 112, and the upper box body 111 and the lower box body 112 are connected by a plurality of fasteners 140. The design of the mounting box 110 composed of the upper box body 111 and the lower box body 112 connected by a plurality of fasteners 140 greatly improves the maintainability and workmanship of the equipment. This split structure allows the upper box body 111 to be removed by loosening the fasteners 140 without the need to disassemble the entire gear box during maintenance, replacement of internal transmission components 210, or daily maintenance, thereby providing sufficient accessibility to internal core components and significantly simplifying the operation process and shortening downtime. At the same time, this design also reduces the casting and machining difficulty of the box itself, improves production efficiency, and allows precise control of the compression degree of the box joint surface by adjusting the pre-tightening force of the fasteners 140, achieving an optimal balance between manufacturing and maintenance costs while ensuring the overall structural rigidity and sealing reliability.

[0060] Some embodiments of the present application also disclose an extruder gearbox 200, comprising a transmission component 210 and an extruder gearbox 200 box.

[0061] As shown in Figure 1 , Figure 4 and Figure 9 , the transmission component 210 is mounted on the mounting box 110. The design of integrating the transmission component 210 inside the mounting box 110 provides a stable, sealed and independent running environment for the gears, bearings and other components of the transmission component 210, which not only effectively isolates the intrusion of external dust and foreign matter, ensuring the reliability and service life of long-term operation, but also closely links the heat source (transmission component 210) and the heat dissipation surface (mounting box 110 wall) in structure, building an efficient heat management foundation. At the same time, this layout makes each mounting box 110 can be assembled, debugged and maintained as an independent functional unit. When a transmission component 210 needs to be repaired, the mounting box 110 where it is located can be operated specifically without disassembling the entire transmission system, greatly improving the convenience and efficiency of maintenance and reducing the operation and maintenance cost.

[0062] As shown in Figure 9 , at least part of the transmission component 210 is exposed in the gap 150. By exposing at least part of the transmission component 210 in the gap 150, the most direct heat dissipation method is created for the most critical heat source area. The large amount of friction heat generated by this part of the transmission component 210 during work can bypass the thermal resistance of the box wall and directly exchange heat with the outside air in an efficient convection. This fundamentally solves the problem of overheating and lubrication failure of the internal transmission component 210 of the traditional closed gearbox due to heat accumulation and long transmission path, thereby significantly reducing the peak working temperature of the extruder gearbox 200, improving the transmission efficiency, and prolonging the service life of the key components.

[0063] It should be noted that the part of the transmission component 210 exposed in the gap 150 is a main shaft of the transmission component 210. The contact part between the main shaft and the mounting box 110 is provided with a sealing assembly, which can effectively prevent the leakage of lubricating oil inside the mounting box 110 to the outside, and block the intrusion of pollutants such as dust and water vapor into the box interior while allowing the main shaft to rotate freely.

[0064] It should be noted that, as used herein, the terms "includes," "including," or "has" are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements is not limited to those elements, but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a... " does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element.

[0065] Further, it is to be understood that the scope of the present application is not limited to the exact details of construction, mechanism, or arrangement of parts shown and described, nor exclusively to the exact sequence of steps described, for carrying out the methods described in the application, but one skilled in the art could make various changes, modifications, and substitutions thereto without departing from the application.

Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
