[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear and understandable, the following will further describe the present invention in detail with reference to specific embodiments.

[0024] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a detachable lubricating oil circulation device for a speed reducer includes a speed reducer housing 1, and a circulation device is arranged outside the speed reducer housing 1; the circulation device includes a threaded telescopic pipe 2 installed on one side of the speed reducer housing 1, and the other side of the threaded telescopic pipe 2 is threadedly connected to a temporary oil storage tank 3. An exhaust unit 5 is fixedly installed on the top of the temporary oil storage tank 3, and a square cover 4 is detachably installed on the top of the temporary oil storage tank 3. A metal chain 9 is connected to the bottom of the square cover 4, and the end of the metal chain 9 is fixedly connected to a magnet 10, and the magnet 10 is arranged inside the temporary oil storage tank 3; the other side of the temporary oil storage tank 3 is connected to a spiral cooling rod 6, an oil pump 7 is arranged outside the temporary oil storage tank 3, the top end of the spiral cooling rod 6 is connected to the input end of the oil pump 7, and the output end of the oil pump 7 is connected to a hose 8, and the end of the hose 8 is fixedly connected to the top end of the speed reducer housing 1.

[0025] In this embodiment, the temporary oil storage tank 3 and the speed reducer housing 1 are integrally connected by the threaded telescopic pipe 2, the spiral cooling rod 6 is installed between the speed reducer housing 1 and the oil pump 7, and the hose 8 is installed between the oil pump 7 and the speed reducer housing 1, which is convenient for disassembly and installation and is not limited to the use environment;

[0026] When the speed reducer overheats during operation, the lubricating oil flows into the temporary oil storage tank 3 through the threaded telescopic pipe 2 with the impurities inside the speed reducer housing 1 carried by the agitated bubbles, increasing the internal space of the speed reducer housing 1. The lubricating oil with gas will move upward due to density, enter the exhaust unit 5, and part of the gas liquefies. The non-vaporized lubricating oil passes through the double filtration of the magnet 10 and the filter screen 11 to remove the impurities in the lubricating oil, passes through the inside of the spiral cooling rod 6 under the suction of the oil pump 7, then enters the hose 8, and then is sprayed through the hose 8 and enters the inside of the speed reducer housing 1 again. While the lubricating oil is circulated as a whole, the internal parts of the speed reducer housing 1 are better lubricated and cooled.

[0027] As an embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the exhaust unit 5 includes a mounting flange 51 fixedly installed on the top of the temporary oil storage tank 3, a exhaust pipe 52 is fixedly installed on the top of the mounting flange 51, a spiral exhaust channel 53 is installed inside the exhaust pipe 52, and a piston 54 is clamped at the top end of the exhaust pipe 52. A oil separation filter screen 55 is detachably installed at the bottom end of the piston 54, and a cover plate 57 is fixedly installed at the top end of the piston 54.

[0028] In this embodiment, the lubricating oil with gas will move upward under the influence of density and enter the spiral exhaust passage 53 of the exhaust unit 5. Part of the gas liquefies, and the lubricating oil slides down along the spiral exhaust passage 53. The moisture is absorbed by the spiral exhaust passage 53 made of silicone rubber. The remaining gas and the unliquefied lubricating oil continue to move upward. The lubricating oil is completely blocked inside the exhaust unit 5 by the oil separation filter screen 55. The gas then pushes up the piston 54 and is released to the outside air through the exhaust holes 12 on the side of the piston 54. When the gas inside the speed reducer decreases and there is no thrust on the piston 54, it falls back with the cover plate 57 to form a seal.

[0029] As an embodiment, as Figure 3 and Figure 4 shown, the exhaust pipe 52 has a trapezoidal structure, and the spiral exhaust passage 53 is a component made of silicone rubber. The spiral exhaust passage 53 and the exhaust pipe 52 are detachably installed.

[0030] In this embodiment, the disassemblable glue fits closely to the inner wall of the trapezoidal exhaust pipe 52, facilitating disassembly and cleaning. The spiral structure of the spiral exhaust passage 53 and the silicone rubber wall surface work together. When blocking the lubricating oil carried by the gas, it is more conducive to the lubricating oil sliding down along the spiral exhaust passage 53. At the same time, the silicone rubber can absorb the moisture generated after liquefaction, preventing the moisture from flowing back to the temporary oil storage tank 3, reducing the viscosity of the lubricating oil, and extending the service life of the lubricating oil.

[0031] As an embodiment, as Figure 3 and Figure 4 shown, the outer side of the piston 54 is provided with exhaust holes 12 arranged in an array, and the spiral exhaust passage 53 is communicated with the temporary oil storage tank 3.

[0032] In this embodiment, when the gas continues to rise along the spiral exhaust passage 53, it will push the piston 54 upward, and the exhaust holes 12 are exposed. The gas is discharged through the exhaust holes 12. When there is no gas discharge, the piston 54 falls back to form a seal. As an embodiment, as Figure 4 shown, hooks 56 are installed on one side of the oil separation filter screen 55 and the cover plate 57, and on the upper and lower sides inside the piston 54. The hooks 56 are arranged in an L-shaped structure.

[0033] In this embodiment, the piston 54, the oil separation filter screen 55, and the cover plate 57 are connected by the hooks 56, facilitating the disassembly of the cover plate 57, the piston 54, and the oil separation filter screen 55 for daily maintenance and cleaning. The piston 54 and the exhaust pipe 52 play a role in positioning and sealing. The oil separation filter screen 55 blocks the lubricating oil carried by the gas and the outside dust, which is conducive to cleaning and wiping.

[0034] As an embodiment, as Figure 1 and Figure 5As shown in the figure, a lotus nozzle 82 is fixedly installed at the end of the hose 8. The lotus nozzle 82 is arranged inside the reducer housing 1. A lotus cover 81 is fixedly installed at the connection between the hose 8 and the reducer housing 1. The lotus nozzle 82 and the lotus cover 81 are arranged parallel to each other up and down.

[0035] In this embodiment, the relatively large diameter of the lotus cover 81 is used to seal and support the hose 8, preventing the hose 8 from entering the interior of the reducer housing 1 too much. The lotus nozzle 82 is located inside the reducer housing 1. The lubricating oil in the temporary storage tank 3 is pumped out through the spiral cooling rod 6 by the oil pump 7, sprayed through the lotus nozzle 82, and then re-enters the interior of the reducer housing 1 for circulation.

[0036] As an embodiment, as Figure 1 、 Figure 2 shown, an opening 32 matching the square cover 4 is provided on the temporary storage tank 3, and an observation port 31 is provided outside the temporary storage tank 3. Glass is arranged inside the observation port 31.

[0037] In this embodiment, the state of the lubricating oil can be observed at any time through the observation port 31, which is convenient for confirming the lubricating oil replacement time. When replacing, the square cover 4 can be opened, and the lubricating oil can be sucked out or poured out through the opening 32, and the temporary storage tank 3 can be cleaned, and the lubricating oil can be supplemented and cleaned.

[0038] As an embodiment, as Figure 2 shown, a filter screen 11 is arranged at the connection between the temporary storage tank 3 and the spiral cooling rod 6.

[0039] In this embodiment, the filter screen 11 is detachably connected to the temporary storage tank 3, which is convenient for disassembly, cleaning and replacement. When the interior of the reducer housing 1 is running, a large number of bubbles will be generated. Under the action of the bubbles, the impurities inside the reducer housing 1 can be fully mixed with the lubricating oil, and then the impurities can be brought out into the temporary storage tank 3. Therefore, the filter screen 11 can act together with the magnetic block 10 adsorption as a second-stage filtration to effectively remove the impurities in the lubricating oil and save costs.

[0040] Working principle: When in use, first connect the temporary storage tank 3 and the reducer housing 1 through the threaded telescopic pipe 2. A spiral cooling rod 6 is installed between the reducer housing 1 and the oil pump 7, and a hose 8 is installed between the oil pump 7 and the reducer housing 1, which is convenient for disassembly and assembly and is not limited to the use environment;

[0041] When there is no overheating phenomenon in the speed reducer, the lubricating oil uses the agitated bubbles to carry the impurities inside the speed reducer housing 1 and flows into the temporary oil storage tank 3 through the threaded telescopic pipe 2. After being double-filtered by the magnetic block 10 and the filter screen 11, the impurities in the lubricating oil can be well removed. Under the suction of the oil pump 7, it enters the hose 8 through the spiral cooling rod 6 and is sprayed into the speed reducer housing 1 through the lotus leaf nozzle 82. Spraying with the lotus leaf nozzle 82 can better lubricate the internal parts of the speed reducer housing 1;

[0042] When there is an overheating phenomenon during the operation of the speed reducer, the lubricating oil uses the agitated bubbles to carry the impurities inside the speed reducer housing 1 and flows into the temporary oil storage tank 3 through the threaded telescopic pipe 2, which can quickly increase the internal space of the speed reducer housing 1. The lubricating oil with gas will move upward due to density influence and enter the spiral exhaust channel 53 of the exhaust unit 5. Part of the gas liquefies, and the lubricating oil slides down along the spiral exhaust channel 53. The moisture is absorbed by the spiral exhaust channel 53 made of silicone rubber material. The remaining gas and the unliquefied lubricating oil continue to move upward. The lubricating oil is completely blocked inside the exhaust unit 5 through the oil separation filter screen 55. The gas then pushes up the piston 54 and is released to the outside air through the exhaust hole 12 on the side of the piston 54. When the gas inside the speed reducer decreases and the piston 54 has no thrust, it falls back with the cover plate 57 to form a seal;

[0043] The non-vaporized lubricating oil is double-filtered by the magnetic block 10 and the filter screen 11 to remove the impurities in the lubricating oil. Under the suction of the oil pump 7, it passes through the spiral cooling rod 6, which can increase the contact between the lubricating oil and the wall surface of the spiral cooling rod 6, accelerate the heat dissipation of the lubricating oil and effectively reduce the temperature. Then it enters the hose 8 and is sprayed into the speed reducer housing 1 through the lotus leaf nozzle 82. Spraying with the lotus leaf nozzle 82 can better lubricate and cool the internal parts of the speed reducer housing 1.
