Description

Technical Field

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

Then, under the action of the second delivery pump, the connecting pipe, the heat conducting pipe, and the delivery pipe, the lubricating oil is transported and enters the reducer. At the same time, under the cooperation of the first motor, the heat dissipation fins, the fan blades, and the ventilation slots, the lubricating oil inside the heat conducting pipe can be cooled, making the lubricating oil entering the reducer at a lower temperature, improving the absorption of the heat inside the reducer. Then, under the cooperation of the first delivery pump, the return pipe, and the oil delivery pipe, the lubricating oil that has absorbed heat is transported into the delivery box, and under the action of the cooling device, the circulation pump, and the cooling pipe, the lubricating oil that has absorbed heat can be cooled, making the lubricating oil have a better cooling effect and absorb heat faster during subsequent use, thereby improving the cooling effect of the reducer, preventing the internal components from being damaged due to high temperature, extending its service life, and reducing the maintenance cost.

[0016] 2. During the use of the present invention, when the lubricating oil absorbs heat inside the reducer, due to the continuous operation of the reducer, debris generated by the friction of the internal components of the reducer will remain in the lubricating oil. When the lubricating oil is transported out of the reducer, through the cooperation of the filter box, the filter plate, and the magnetic filter plate, the debris inside the lubricating oil can be filtered and adsorbed, preventing the debris from moving with the lubricating oil and accumulating inside subsequent delivery structures such as the first delivery pump and the oil delivery pipe, causing blockage, thereby greatly improving the circulating delivery effect of the lubricating oil and preventing the delivery structure from being blocked and affecting the cooling effect of the reducer.

[0017] 3. During the use of the present invention, when using lubricating oil to cool down the inside of the reducer, by transporting the lubricating oil to make it circulate inside the reducer, and during the movement process, through the cooperation of the filter plate and the magnetic filter plate, the lubricating oil is cleaned, which can greatly improve the service life of the lubricating oil and slow down the aging speed of the lubricating oil, thereby greatly improving the lubricating effect of the lubricating oil on the internal components of the reducer and at the same time improving the cooling effect of the reducer.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Example 1, refer to Figures 1-8 As shown: The present invention provides a hanging ring-shaped star wheel reducer, including a mounting frame 1. The bottom of the inner wall of the mounting frame 1 is fixedly installed with a support frame 10. The top of the support frame 10 is fixedly installed with a delivery box 11.

The outer surface of the cooling device 13 is fixedly communicated with the outer surface of the cooling pipe 12. One side of the outer wall of the support frame 10 is fixedly installed with a circulation pump 14. The outer surface of the circulation pump 14 is fixedly communicated with the outer surface of the cooling pipe 12. One side of the outer wall of the delivery box 11 is fixedly communicated with a connecting pipe 15. The bottom of the inner wall of the mounting frame 1 is fixedly installed with a storage tank 16. One side of the outer wall of the storage tank 16 is fixedly communicated with the outer surface of the connecting pipe 15. The top of the storage tank 16 is provided with an oil filling port 17. One side of the outer wall of the storage tank 16 is fixedly communicated with a connecting pipe 18.

[0022] In this embodiment, when the lubricating oil transported into the hanging ring planetary gear reducer absorbs heat, under the action of the conveying device, it is transported into the inside of the conveying box 11. Since the conveying box 11 has a certain inclination angle, the lubricating oil transported into the inside of the conveying box 11 will move slowly downward under the action of gravity. When the lubricating oil is moving downward, under the action of the circulation pump 14, the coolant inside the cooling pipe 12 can be circulated. Since the conveying box 11 is made of a heat-conducting material, therefore, through the movement of the coolant inside the cooling pipe 12, part of the heat of the lubricating oil inside the conveying box 11 can be absorbed. The coolant that has absorbed the heat will continue to move into the cooling device 13. Through the cooperation of the semiconductor heat dissipation device and the fan inside the cooling device 13, the coolant can be quickly and efficiently cooled, so that it can continuously cool the lubricating oil inside the conveying box 11 for a long time, making it more convenient for subsequent use. The lubricating oil continuously moves inside the conveying box 11, enters the storage tank 16 through the connecting pipe 15, and with the cooperation of other structures, the continuous cooling and circulating movement of the lubricating oil can be realized, thereby improving the cooling effect on the reducer.

[0023] Embodiment 2, as shown in Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a second delivery pump 19 is fixedly installed at the bottom of the inner wall of the mounting frame 1. The outer wall of the second delivery pump 19 is fixedly communicated with the outer wall of the connecting pipe 18. A fixing frame 20 is fixedly installed at the bottom of the inner wall of the mounting frame 1. A plurality of ventilation slots 21 are formed on one side of the outer wall of the fixing frame 20. A heat-conducting pipe 22 is provided on the inner wall of the fixing frame 20. The outer wall of the heat-conducting pipe 22 is fixedly communicated with the outer wall of the connecting pipe 18. A heat dissipation fin 23 is provided on the inner wall of the fixing frame 20. The heat dissipation fin 23 is arranged on the outer wall of the heat-conducting pipe 22. Two fixing plates 24 are fixedly installed on the inner wall of the fixing frame 20. A first motor 25 is fixedly installed on one side of the outer wall of each of the two fixing plates 24. A fan blade 26 is fixedly sleeved on the output end of each of the two first motors 25.

[0024] In this embodiment, when it is necessary to cool down the hanging ring star wheel reducer, first, under the operation of the staff, lubricating oil is transported from the oil injection port 17 to the inside of the storage tank 16. Then, under the action of the second transfer pump 19 and the connecting pipe 18, the lubricating oil inside the storage tank 16 can be sucked out and transported into the heat conduction pipe 22. Since the heat conduction pipe 22 is made of a material with good heat conductivity, under the action of the first motor 25, the fan blade 26, and the ventilation groove 21, the air circulation inside the fixing frame 20 can be accelerated. With the cooperation of the heat dissipation fins 23, the lubricating oil inside the heat conduction pipe 22 can be cooled down, making the lubricating oil transported into the reducer have a lower temperature, greatly improving the cooling effect on the reducer, preventing the internal components from being damaged due to excessive temperature, and reducing the cost consumption.

[0025] Embodiment 3, according to Figure 1 , Figure 2 , Figure 4 and Figure 8 as shown, a drive motor 2 is fixedly installed on the top of the mounting frame 1, a reducer main body 3 is fixedly installed on the top of the mounting frame 1, the input end of the reducer main body 3 is fixedly connected to the output end of the drive motor 2, a return pipe 4 is fixedly communicated with the outer wall of the reducer main body 3, a filter box 5 is fixedly installed on the top of the mounting frame 1, one side of the outer wall of the filter box 5 is fixedly communicated with the outer wall of the return pipe 4, a magnetic filter plate 6 is arranged on the inner wall of the filter box 5, two filter plates 7 are arranged on the inner wall of the filter box 5, an oil delivery pipe 8 is fixedly communicated with one side of the outer wall of the filter box 5, a first transfer pump 9 is fixedly installed on the top of the mounting frame 1, the outer wall of the first transfer pump 9 is fixedly communicated with the outer wall of the oil delivery pipe 8, the outer wall of the oil delivery pipe 8 is fixedly communicated with one side of the outer wall of the delivery box 11, a delivery pipe 27 is fixedly communicated with the outer wall of the reducer main body 3, and the outer wall of the delivery pipe 27 is fixedly communicated with the outer wall of the heat conduction pipe 22.

[0026] In this embodiment, during the working process of the hanging ring star wheel reducer, after the lubricating oil inside it absorbs heat, under the action of the first transfer pump 9 and the oil delivery pipe 8, negative pressure is generated inside the filter box 5. At the same time, under the action of the return pipe 4, the lubricating oil inside the reducer is transported into the filter box 5. Under the action of the filter plate 7 and the magnetic filter plate 6, the debris generated by the wear of the reducer components retained in the lubricating oil can be filtered and adsorbed, preventing the debris in the lubricating oil from continuously moving with the lubricating oil, thus protecting the subsequent conveying structure, avoiding the debris from staying inside the subsequent structure and causing blockage, prolonging the service life of the subsequent conveying structure, and by cleaning the debris in the lubricating oil, the lubricating oil can be protected, preventing the lubricating oil from aging too quickly, and further improving the lubrication and cooling effects of the lubricating oil.

[0027] The working principle of the entire mechanism is as follows: When the hanging ring gear reducer is used intensively for a long time, a large amount of heat will be generated inside it. At this time, under the operation of the staff, lubricating oil is transported from the oil injection port 17 into the storage tank 16. Then, under the action of the second transfer pump 19 and the connecting pipe 18, the lubricating oil inside the storage tank 16 can be sucked out and transported into the heat conduction pipe 22. Since the heat conduction pipe 22 is made of a material with good heat conductivity, under the action of the first motor 25, the fan blade 26 and the ventilation groove 21, the air circulation inside the fixing frame 20 can be accelerated, and with the cooperation of the heat dissipation fins 23, the lubricating oil inside the heat conduction pipe 22 can be cooled. Subsequently, the lubricating oil after the cooling treatment will continue to move under the action of the second transfer pump 19 and enter the hanging ring gear reducer through the transfer pipe 27. With the continuous operation of the reducer, it will carry the lubricating oil to move together, so that the lubricating oil entering the reducer can quickly and fully absorb the heat generated by its internal components. When the lubricating oil absorbs heat, under the action of the first transfer pump 9 and the oil pipe 8, a negative pressure is generated inside the filter box 5. At the same time, under the action of the return pipe 4, the lubricating oil inside the reducer is transported into the filter box 5. Through the action of the filter plate 7 and the magnetic filter plate 6, the debris generated by the wear of the reducer components retained in the lubricating oil can be filtered and adsorbed, preventing the debris inside the lubricating oil from moving continuously with the lubricating oil, thus playing a protective role for the subsequent conveying structure. After the lubricating oil is filtered and adsorbed, under the action of the first transfer pump 9 and the oil pipe 8, the lubricating oil that has absorbed heat can enter the conveying box 11. Since the conveying box 11 has a certain inclination angle, the lubricating oil transported into the conveying box 11 will slowly move downward under the action of gravity. When the lubricating oil is moving downward, under the action of the circulation pump 14, the coolant inside the cooling pipe 12 can circulate. Since the conveying box 11 is made of a heat-conducting material, therefore, through the movement of the coolant inside the cooling pipe 12, part of the heat of the lubricating oil inside the conveying box 11 can be absorbed. The coolant that has absorbed heat will continue to move into the cooling device 13. Through the cooperation of the semiconductor heat dissipation device and the fan inside the cooling device 13, the coolant can be quickly and efficiently cooled, enabling it to continuously cool the lubricating oil inside the conveying box 11 for a long time, making it more convenient for subsequent use. The lubricating oil continuously moves inside the conveying box 11, enters the storage tank 16 through the connecting pipe 15, and then through the above structure and method again, the lubricating oil can continuously circulate inside the hanging ring gear reducer, thereby cooling the hanging ring gear reducer and lubricating the components inside the hanging ring gear reducer, reducing the friction between the components and extending its service life. Since the debris in the lubricating oil will be cleaned during the continuous circulation process of the lubricating oil, the service life of the lubricating oil can be extended.Avoid the lubricating oil from aging too fast, thereby improving the lubricating and cooling effects of the lubricating oil.
