[0002] The worm gear box is a key component commonly used in mechanical transmission systems, mainly used for speed reduction and torque amplification; it transmits power through the engagement of the worm and the worm wheel, while changing the speed and torque, transmitting high-speed and low-torque power to a low-speed and high-torque system.

[0003] When the worm is transmitting torque, both ends of the worm, as the transmission points of torque, will be subjected to greater stress. This continuous torque transmission will cause stress accumulation at both ends of the worm, especially under high load and high-speed operation and poor lubrication conditions. This stress concentration is more serious, which increases the risk of fatigue fracture, and this abnormal stress concentration will cause the material properties of both ends of the worm to deteriorate, such as elastic modulus, yield strength, etc., which will further affect the overall performance of the worm. The performance degradation will reduce the efficiency of the worm when transmitting torque, and even generate vibration and noise, affecting the overall performance of the worm gear box.

[0022] Reference Figure 1-Figure 14, including a cover shell 1 and a bottom shell 2, and also including: an oil inlet 101 arranged at the top of the cover shell 1; an oil outlet 201 arranged at the bottom of the bottom shell 2; a worm wheel 5 and a worm 6 are arranged in the worm gear box composed of the cover shell 1 and the bottom shell 2, and the worm wheel 5 and the worm 6 are meshed and connected; a first gear 7 rotates synchronously with the worm 6, the first gear 7 is arranged in the bottom shell 2, and a plurality of second gears 8 are meshed and connected on the first gear 7; a vertical pipe 11 is arranged in the bottom shell 2, and the top end of the vertical pipe 11 is connected to a cone tube 9, and an impeller 25 is arranged in the cone tube 9, and the impeller 25 is fixedly connected to the second gear 8, and the cone tube 9 is connected to the nozzle 10; a sliding plate 23 is arranged at the lower end of the vertical pipe 11, and an opening 2301 is opened on the sliding plate 23; an adjusting part 24 cooperates with the sliding plate 23 to control the amount of oil injection; the bottom shell 2 A fixing ring 17 is provided inside, and a semicircular convex tooth 1701 is provided on the fixing ring 17, and the arc protruding end of the semicircular convex tooth 1701 faces the shaft body of the worm 6 and fits with the shaft body of the worm 6; a support plate 18 is fixedly connected to the bottom of the fixing ring 17; a bottom plate 21 is provided at the bottom of the sliding plate 23, and a retreat rod 20 is provided on the bottom plate 21, and the retreat rod 20 passes through the support plate 18, and a second spring 19 is provided between the bottom plate 21 and the support plate 18, and the second spring 19 is sleeved on the retreat rod 20; the adjusting part 24 is divided into a slope section 2402, a blocking section 2403 and a supporting section 2404 from top to bottom, and a slot 2401 is provided on the supporting section 2404, and the slot 2401 is aligned with the bottom slot 1101; in the initial state, the sliding plate 23 is located in the blocking section 2403.

[0023] In the present invention, lubricating oil is injected into the worm gear box through the oil inlet 101, and waste oil is discharged through the oil outlet 201 for replacement; Under low load and low speed operation, the worm 6 drives the first gear 7 to rotate synchronously, the first gear 7 drives the second gear 8 to rotate, and the second gear 8 drives the impeller 25 to rotate, so that the impeller 25 extracts the medium in the riser 11, so that negative pressure is formed in the riser 11. At the initial stage or at a low speed, since the negative pressure formed by the impeller 25 is not large, the sliding plate 23 in the riser 11 is located at the blocking section 2403 and moves on the blocking section 2403, and the lubricating oil at the bottom of the bottom shell 2 is sucked into the nozzle 10 through the opening 2301, and is sprayed by the nozzle 10 to the worm wheel 5 and the worm 6 to lubricate the worm wheel 5 and the worm 6; Under high load and high speed operation, the heat generated by the worm wheel 5 and the worm 6 is greater, the worm 6 drives the first gear 7 to rotate synchronously, the first gear 7 drives the second gear 8 to rotate, and the second gear 8 drives the impeller 25 to rotate, so that the impeller 25 extracts the medium in the riser 11, so that a negative pressure is formed in the riser 11. Since the worm 6 rotates at a high speed, the impeller 25 also rotates at a high speed, and a strong negative pressure can be formed in the riser 11, and the sliding plate 23 can be further lifted to the slope section 2402, so that more lubricating oil enters the nozzle 10 with a greater pressure, and the lubricating oil sprayed from the nozzle 10 to the worm wheel 5 and the worm 6 has a stronger impact force, which can more effectively take away the heat generated by the worm wheel 5 and the worm 6 during operation, and reduce the working temperature of the worm 6 and the worm wheel 5. The reduction in temperature helps to reduce deformation and stress concentration caused by thermal stress; at the same time, the lubricating oil can reduce the friction and wear between the worm 6 and the worm wheel 5, and the lubricating oil can extend their service life and reduce the risk of performance degradation and stress concentration caused by wear; The lubricating oil impacts the worm 6 and the worm wheel 5, and can remove impurities and dirt on the surface of the worm 6 and the worm wheel 5, keeping them clean and smooth, which helps to reduce friction and stress concentration caused by impurities; In one embodiment, under high load and high speed operation, when the worm 6 transmits torque, its two ends as the torque transmission points will be subjected to greater stress. This continuous torque transmission will cause stress accumulation at both ends of the worm 6. Under long-term uneven stress, the material of the worm 6 is prone to fatigue, which reduces its service life. In addition, due to stress concentration and wear, the transmission accuracy and stability of the worm 6 will be affected, resulting in larger transmission errors. The high load and high speed operation of the worm 6 causes the impeller 25 to rotate at a high speed, and a strong negative pressure is formed in the riser 11, so that the sliding plate 23 rises and slides to the slope section 2402, and the bottom The plate 21 presses the second spring 19 upward, and the second spring 19 compresses and pushes the support plate 18. The support plate 18 is forced to push the fixing ring 17 upward, so that the semicircular convex teeth 1701 apply an extrusion force to the shaft body of the worm 6. The worm 6 is compressed and continues to rotate. The semicircular convex teeth 1701 squeeze the shaft body of the worm 6, and the stress is released by changing the internal stress distribution of the worm 6 and generating plastic deformation through such squeezing. During the squeezing process, the worm 6 is subjected to a uniform pressure distribution, which helps to reduce the local stress peak; at the same time, the plastic deformation will cause the internal stress to be released, thereby extending the service life of the worm 6 and avoiding large transmission errors; And as the speed of the worm 6 increases, the accumulated stress at both ends of the worm 6 will increase. At the same time, the worm 6 increases the output of the impeller 25 to form a stronger negative pressure in the riser 11, allowing the sliding plate 23 to rise and slide to a higher position of the slope section 2402, so that the gap between the sliding plate 23 and the slope section 2402 is increased, and the amount and impact force of the lubricating oil sprayed by the nozzle 10 are increased, so as to lubricate the worm wheel 5 and the worm 6 more comprehensively. At the same time, since the sliding plate 23 rises and slides to a higher position of the slope section 2402, the bottom plate 21 further presses the second spring 19 upward, and the second spring 19 further compresses and pushes the support plate 18. The support plate 18 is further forced to push the fixing ring 17 upward, so that the semicircular convex teeth 1701 exert a greater extrusion force on the shaft body of the worm 6 to adapt to the increase in the speed of the worm 6, resulting in the increase in the accumulated stress at both ends of the worm 6.

[0024] Reference Figure 1-Figure 14 The worm wheel 5 is fixedly connected with the output shaft 3, the worm 6 is fixedly connected with the input shaft 4, both the output shaft 3 and the input shaft 4 extend outside the worm gear box, and the first gear 7 is arranged on the input shaft 4; a bottom groove 1101 is provided at the bottom of the riser 11, and the adjusting part 24 is provided at the bottom of the riser 11; the adjusting part 24 is divided into a slope section 2402, a blocking section 2403 and a supporting section 2404 from top to bottom, and a slot 2401 is provided on the supporting section 2404, and the slot 2401 is aligned with the bottom groove 1101; in the initial state, the sliding plate 23 is located in the blocking section 2403.

[0025] In the present invention, the input shaft 4 drives the worm 6 to rotate and drives the first gear 7 to rotate synchronously. The vertical pipe 11 can be fixed in the bottom shell 2 through a fixing plate. Specifically, the side of the vertical pipe 11 can be fixed to the side inside the bottom shell 2 through a fixing plate.

[0026] In one embodiment, when under high load and high speed operation, the worm 6 simultaneously increases the output of the impeller 25 to form a stronger negative pressure in the riser 11, allowing the sliding plate 23 to rise and slide to a higher position of the ramp section 2402, thereby increasing the gap between the sliding plate 23 and the ramp section 2402, increasing the amount and impact force of the lubricating oil sprayed by the nozzle 10, and more comprehensively lubricating the worm wheel 5 and the worm 6. The stronger impact force can more effectively take away the heat generated at the meshing point of the worm wheel 5 and the worm 6 to cope with different operating conditions.

[0027] Reference Figure 1-Figure 14 A connecting rod 22 is fixedly connected to the bottom of the sliding plate 23, and the connecting rod 22 is fixedly connected to the bottom plate 21; a fixing rod 15 is provided in the bottom shell 2, and both ends of the fixing ring 17 are slidably connected to the fixing rod 15, and a first spring 16 is provided between the two ends of the fixing ring 17 and the top of the fixing rod 15, and the first spring 16 is sleeved on the fixing rod 15.

[0028] In the present invention, the sliding plate 23 moves upward, driving the bottom plate 21 to move upward through the connecting rod 22; The fixing rod 15 cooperates with the first spring 16 to preliminarily fix the fixing ring 17 .

[0029] Reference Figure 1-Figure 14 A heat exchange chamber 12 is provided below the input shaft 4, and a heat sink 1201 is provided in the heat exchange chamber 12. Inlet pipes 13 are connected to both sides of the heat exchange chamber 12, and an exhaust pipe 14 is connected to the top surface of the heat exchange chamber 12; a section of the intake pipe 13 toward the outside of the bottom shell 2 is inclined downward, and a section of the exhaust pipe 14 toward the outside of the bottom shell 2 is inclined upward.

[0030] In the present invention, a heat sink 1201 is provided inside the heat exchange chamber 12, and a heat sink 1201 may also be provided outside the heat exchange chamber 12, so as to better absorb the heat inside the worm gear box. The heat in the heat exchange chamber 12 is high. According to the Bernoulli principle, in the channel formed by the heat exchange chamber 12 and the air inlet pipe 13, the air in the heat exchange chamber 12 has a large heat quantity, and the external cold air will enter the heat exchange chamber 12 through the air inlet pipe 13, thereby forming an airflow. The hot air in the heat exchange chamber 12 rises, and under the impact of the cold air flow discharged into the heat exchange chamber 12 through the air inlet pipe 13, the hot air in the heat exchange chamber 12 will be discharged through the exhaust pipe 14. By designing a section of the air intake pipe 13 that is tilted downward toward the outside of the bottom shell 2 and a section of the exhaust pipe 14 that is tilted upward toward the outside of the bottom shell 2, the air in the heat exchange chamber 12 can flow more smoothly and the heat exchange effect can be better. The upward tilted structure of the exhaust pipe 14 can facilitate the outflow of hot air, and the downward tilted structure of the air intake pipe 13 can prevent hot air from being discharged through the air intake pipe 13, thereby avoiding airflow chaos and being unfavorable for heat dissipation.

[0031] Reference Figure 1-Figure 14 The number of the nozzles 10 is consistent with the number of the second gears 8 , and the output end of the nozzle 10 is directly opposite to the meshing position of the worm wheel 5 and the worm 6 .

[0032] In the present invention, a plurality of nozzles 10 are provided, and the nozzles 10 are directed to the meshing part of the worm wheel 5 and the worm 6, so that the lubricating oil can directly hit the heat generating point. The cooperation of the plurality of nozzles 10 can perform heat dissipation, lubrication, and decontamination more comprehensively. The lubricating oil deteriorates or is contaminated by pollutants, and foreign matter is formed in the worm wheel 5 and the worm 6, which will reduce the lubricating effect of the lubricating oil and increase the friction. The foreign matter in the meshing part of the worm wheel 5 and the worm 6 can be removed by directly spraying oil on the meshing part of the worm wheel 5 and the worm 6 through the nozzles 10. In a high temperature environment, the lubricating oil will fail due to oxidation, which will manifest as blackening and thickening. At this time, the performance of the lubricating oil has been significantly reduced and may no longer meet the lubrication needs of the equipment. The meshing area of ​​the worm wheel 5 and the worm 6 is the main part that generates heat. If the lubricating oil does not flow at the meshing area of ​​the worm wheel 5 and the worm 6 for a long time, the lubricating oil in this area is exposed to a high temperature environment for a long time and is easily oxidized and deteriorated. The lubricating oil sprayed from the nozzle 10 can impact the meshing area of ​​the worm wheel 5 and the worm 6, which can bring better lubrication effect to the meshing area of ​​the worm wheel 5 and the worm 6, reduce the friction between the worm wheel 5 and the worm 6, and reduce the generation of heat. The lubricating oil sprayed from the nozzle 10 can impact the lubricating oil at the meshing area of ​​the worm wheel 5 and the worm 6, so as to replace the lubricating oil at the meshing area of ​​the worm wheel 5 and the worm 6 in real time, so as to avoid the problem that the lubricating oil at the meshing area of ​​the worm wheel 5 and the worm 6 does not flow for a long time and is easily oxidized and deteriorated.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
