Description

Technical Field

[0001] This application relates to the technical field of transmission devices for straight seam welded pipe machines, specifically a worm gear protection device for high-frequency straight seam welded pipe units. Background Technology

[0002] The worm gear in a high-frequency straight seam welded pipe unit is a mechanical device used for transmission and speed reduction. It consists of two key components: a worm wheel and a worm. During the production process, the high-frequency straight seam welded pipe unit needs to precisely control the movement speed of each component. The worm gear transmission device can convert the high-speed rotation of the motor into a low-speed movement suitable for the welded pipe production process, and transmit power to the corresponding components, such as the feeding mechanism and the welding mechanism, to ensure that these components can work at the set speed and rhythm, thus guaranteeing the quality and production efficiency of the welded pipe.

[0003] To protect themselves, worm gears are often housed in a casing. However, worm gears generate a significant amount of heat during transmission, especially in high-load operating environments such as high-frequency straight seam welded pipe units. If this heat cannot be dissipated in time, it will cause the oil temperature to rise, leading to a decrease in oil viscosity, poor lubrication performance, and accelerated wear of the worm gear. Furthermore, high temperatures can also cause thermal deformation of the worm gear, affecting transmission accuracy.

[0004] In addition, high-frequency straight seam welded pipe units generate a large amount of dust and debris during operation. This dust and debris can easily enter the worm gear transmission mechanism, contaminate the oil, accelerate component wear, and may also affect the normal operation of the equipment.

[0005] Therefore, it is necessary to provide a worm gear protection device for high-frequency straight seam welded pipe units to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] The purpose of this utility model is to provide a worm gear protection device for a high-frequency straight seam welded pipe unit to solve the problems mentioned in the background art.

[0008] The technical solution adopted by this application to solve its technical problem is:

[0009] A worm gear protection device for a high-frequency straight seam welded pipe unit includes a protective housing for mounting the worm gear, a worm gear cavity for rotating the worm gear is provided inside the protective housing, and a worm gear cavity for rotating the worm is provided at the bottom of the protective housing. Oil is injected into the worm gear cavity and the worm gear cavity.

[0010] The sidewall of the worm gear cavity is equipped with a heat-absorbing component, and the protective shell has liquid holes for oil flow on both sides.

[0011] The cooling assembly has its inlet and outlet ends respectively connected to the liquid holes on both sides of the protective housing to exchange heat for the oil in the protective housing.

[0012] Preferably, the heat-absorbing component includes an arc-shaped plate and multiple heat-absorbing fins. The arc-shaped plate is fitted onto the surface of the worm gear cavity, and the multiple heat-absorbing fins are equidistantly arranged and fixed on the arc-shaped plate.

[0013] Preferably, the protective shell has a heat absorption groove inside its side wall, and the two ends of the heat absorption groove are connected to the liquid hole through the inlet hole.

[0014] Preferably, the cooling assembly includes an outlet pipe, a pump body, a cooling chamber, a cooling fan, an inlet pipe, and a mounting bracket. One end of the outlet pipe and the inlet pipe are respectively mounted on liquid holes on both sides of the protective housing via flanges. The pump body is mounted on the outlet pipe. The other ends of the outlet pipe and the inlet pipe are plugged into the inlet and outlet ports of the cooling chamber. The cooling fan is mounted on the top surface of the cooling chamber. The cooling chamber is mounted on the protective housing via the mounting bracket.

[0015] Preferably, the cooling chamber includes two liquid collection chambers and guide plates. The two liquid collection chambers are fixedly connected to both ends of the multiple guide plates, and the interior of the guide plates is hollow. The two liquid collection chambers are connected to the interior of the multiple guide plates, and heat dissipation fins are installed in the gaps between the multiple guide plates. The liquid inlet and outlet ports of the cooling chamber are installed on the liquid collection chambers.

[0016] Preferably, a shaft bracket is sealed and installed on one side of the protective housing, an output shaft is installed inside the worm gear, and sealed bearings and bushings are respectively sleeved on the side walls of the output shaft located on both sides of the worm gear. The output shaft is rotatably installed in the worm gear cavity through the sealed bearing, and an output sealing cover is sealed and installed on the other side of the protective housing through a first washer.

[0017] Preferably, the worm gear is installed inside the input shaft, and sealed bearings are sleeved on the input shafts located on both sides of the worm gear.

[0018] The beneficial effects of this application are:

[0019] 1. Through the coordinated design of heat absorption components, cooling components, and heat absorption tanks, the heat problem generated by the high-load operation of the worm gear is effectively solved. The arc-shaped plate and heat absorption fins quickly absorb the heat of the worm gear cavity, and the heat absorption tank guides the oil to further absorb the transferred heat. The cooling component drives the oil circulation through the pump body. Through the combined action of the guide plate, heat dissipation fins, and cooling fan in the cooling chamber, efficient heat dissipation is achieved, avoiding problems such as oil viscosity reduction and deterioration of lubrication performance caused by excessive oil temperature.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0045] Please see Figure 1-7 The embodiments provided by this utility model are as follows:

[0046] like Figure 1 and Figure 2As shown, a worm gear protection device for a high-frequency straight seam welded pipe unit includes a protective housing 1 for mounting a worm gear 5 and a worm 6. The protective housing 1 has an internal worm gear cavity 12 for rotating the worm gear 5, and a worm gear cavity 11 for rotating the worm 6. Oil is injected into the worm gear cavity 12 and the worm gear cavity 11. The protective housing 1 provides a relatively enclosed space for the worm gear 5 and worm 6. The internal worm gear cavity 12 and worm gear cavity 11 provide space for the rotation of the worm gear 5 and worm 6, respectively. The oil injected into the worm gear cavity 12 and worm gear cavity 11 allows the oil to flow between the teeth of the worm gear 5 and worm 6 when they rotate, providing lubrication and heat dissipation. The protective housing 1 prevents external dust and debris from entering, protecting the worm gear 5 and worm 6 from environmental influences and extending their service life. The lubricating effect of the oil reduces friction between the worm gear 5 and worm 6, lowers wear, and carries away heat generated during transmission, ensuring smooth and efficient transmission.

[0047] like Figure 2 and Figure 3 As shown, specifically, a shaft bracket 2 is sealed and installed on one side of the protective housing 1, and an output shaft 3 is installed inside the worm gear 5. Sealed bearings 7 and bushings 8 are respectively sleeved and installed on the side walls of the output shaft 3 located on both sides of the worm gear 5. The output shaft 3 is rotatably installed in the worm gear cavity 12 through the sealed bearings 7. An output sealing cover 32 is sealed and installed on the other side of the protective housing 1 through the first washer 31. The worm 6 is installed inside the input shaft 4. Sealed bearings 7 are sleeved and installed on the input shaft 4 located on both sides of the worm 6. The input shaft 4 is rotatably installed in the worm gear cavity 11 through the sealed bearings 7. An input sealing cover 42 is sealed and installed on both sides of the bottom of the protective housing 1 through the second washer 41.

[0048] The output shaft 3 is installed inside the worm gear 5 and rotates within the worm gear cavity 12 via a sealed bearing 7. The sealed bearing 7 ensures the flexible rotation of the output shaft 3 while preventing oil leakage. The bushing 8 provides further support and positioning. The input shaft 4 is installed with the worm gear 6 and also rotates within the worm gear cavity 11 via the sealed bearing 7. The output sealing cover 32 and the input sealing cover 42 are respectively installed at corresponding positions on the protective housing 1 via a first washer 31 and a second washer 41, further enhancing the sealing performance of the protective housing 1. The sealing design effectively prevents oil leakage, maintains the amount of oil in the cavity, and ensures lubrication and heat dissipation. At the same time, the seal also prevents external impurities from entering the cavity, protecting the worm gear 5, worm gear 6, bearings, and other components from contamination, thus improving the reliability and stability of the equipment.

[0049] like Figure 4 and Figure 5As shown, a heat-absorbing component 9 is installed on the side wall of the worm gear cavity 12. The heat-absorbing component 9 includes an arc-shaped plate 91 and multiple heat-absorbing fins 92. The arc-shaped plate 91 is attached to the surface of the worm gear cavity 12, and the multiple heat-absorbing fins 92 are equidistantly arranged and fixed on the arc-shaped plate 91. When the worm gear 5 rotates in the cavity and generates heat, the heat is transferred to the wall of the worm gear cavity 12. The arc-shaped plate 91 absorbs the heat through the multiple heat-absorbing fins 92 connected to it and conducts heat to the side wall of the protective shell 1. The heat-absorbing fins 92 increase the heat absorption area and improve the heat absorption efficiency, thereby reducing the temperature of the worm gear cavity 12, preventing the oil performance from deteriorating and the wear of the worm gear 5 and worm 6 from being too high, and ensuring the normal operation of the worm gear 5 and worm 6.

[0050] like Figure 5 and Figure 7 As shown, liquid holes 15 for oil flow are respectively opened on both sides of the protective housing 1. The inlet and outlet of the cooling component 10 are respectively connected to the liquid holes 15 on both sides of the protective housing 1 to exchange heat for the oil in the protective housing 1.

[0051] Specifically, the cooling assembly 10 includes an outlet pipe 101, a pump body 102, a cooling chamber 103, a cooling fan 104, an inlet pipe 105, and a mounting bracket 106. One end of the outlet pipe 101 and the inlet pipe 105 are respectively mounted on the liquid holes 15 on both sides of the protective housing 1 via flanges. The pump body 102 is mounted on the outlet pipe 101. The other ends of the outlet pipe 101 and the inlet pipe 105 are plugged into the inlet and outlet interfaces of the cooling chamber 103. The cooling fan 104 is mounted on the top surface of the cooling chamber 103. The cooling chamber 103 is mounted on the protective housing 1 via mounting bracket 106. It includes two liquid collection chambers 1031 and guide plates 1032. The two liquid collection chambers 1031 are fixedly connected to both ends of the guide plates 1032, and the guide plates 1032 are hollow. The two liquid collection chambers 1031 are connected to the interior of the guide plates 1032. Heat dissipation fins 1033 are installed in the gaps between the guide plates 1032. The liquid inlet and outlet ports of the cooling chamber 103 are installed on the liquid collection chambers 1031.

[0052] Pump body 102 is mounted on outlet pipe 101, providing power to allow oil in protective housing 1 to flow into cooling chamber 103 through outlet pipe 101. After entering cooling chamber 103, the oil first enters collection chamber 1031, and then flows through the internal channels of guide plate 1032. During this process, heat dissipation fins 1033 dissipate heat from the oil, and cooling fan 104, mounted on the top surface of cooling chamber 103, accelerates airflow and further enhances heat dissipation. The cooled oil flows back to protective housing 1 through inlet pipe 105, forming a circulating cooling system.

[0053] Furthermore, in order to facilitate the heat absorption component 9 in discharging the heat absorbed in the worm gear cavity 12, a heat absorption groove 13 is provided inside the side wall of the protective housing 1. The two ends of the heat absorption groove 13 are connected to the liquid hole 15 through the inlet hole 14. When the oil flows in the protective housing 1, a portion of the oil will flow into the heat absorption groove 13. When the worm gear 5 and worm 6 generate heat during operation, the heat will be transferred to the side wall of the protective housing 1 through the heat absorption component 9. The oil in the heat absorption groove 13 absorbs this heat and then participates in the entire oil circulation through the inlet hole 14 and the liquid hole 15. Finally, it is cooled in the cooling component 10, which further improves the heat absorption capacity of the worm gear 5 and worm 6, thereby providing better protection for the worm gear 5 and worm 6.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
