Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to an automatic lubrication device for a gear reducer. Background Art

[0002] Gear reducer is a common mechanical transmission device used to reduce the speed of the input shaft and increase the torque of the output shaft. It consists of a group of gears, which transmit power through the meshing between the teeth. Inside the gear reducer, gears, bearings and other parts will produce friction and wear when running at high speed. Therefore, it is necessary to use a gear reducer automatic lubrication device to ensure that these parts are always in a good lubrication state, reduce friction and wear, and thus extend the service life of the gear reducer.

[0003] During the use of the traditional gear reducer automatic lubrication device, the electric telescopic rod drives the piston block to extend, and the pressure generated by the sealing cylinder causes the lubricating oil to enter the oil injection pipe through the third connecting pipe and be sprayed on the surface of the gear parts through the nozzle for lubrication.

[0004] However, when the gear reducer is subjected to a higher load, the lubricating oil will heat up, resulting in a higher internal temperature. The traditional heat dissipation structure is large in size and only dissipates heat through a single heat dissipation pipe, resulting in low heat dissipation efficiency. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an automatic lubrication device for a gear reducer, aiming to improve the problem that the traditional heat dissipation structure is large in size and only dissipates heat through a single heat dissipation pipe, resulting in low heat dissipation efficiency.

[0008] The heat dissipation component includes fins, the interior of the fins is fixedly connected to the outer wall of the second cooling tube, and the fins are arranged in a linear array and are fixedly connected to the outer walls of the second cooling tube and the first cooling tube.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the filter is threadedly connected with a sealing cover, and the outer wall of the filter is fixedly connected with fixing blocks arranged in a ring array.

[0011] As a further description of the above technical solution:

[0012] The fixing block is internally slidably connected with a limiting plate, and one side of the limiting plate is fixedly connected with a hemispherical column.

[0013] As a further description of the above technical solution:

[0022] 1. In the utility model, the lubricating oil first enters the upper cooling block 1 through the cooling pipe 1, then enters the upper cooling block 2 and enters the lower cooling block 2 through the cooling pipe 2, thereby achieving the effect of reducing the heat dissipation volume and improving the heat dissipation efficiency. It solves the problem that the traditional heat dissipation structure is large in volume and only dissipates heat through a single heat dissipation pipe, resulting in low heat dissipation efficiency, and improves the heat dissipation efficiency of the automatic lubrication device of the gear reducer.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2The utility model provides an embodiment: an automatic lubrication device for a gear reducer, comprising a housing 1, a gear set 13 is arranged inside the housing 1, an oil outlet pipe 2 is fixedly connected inside the housing 1, one end of the oil outlet pipe 2 is fixedly connected to a filter 3, an outer wall of the filter 3 is fixedly connected to a lower cooling block 4, a top of the lower cooling block 4 is fixedly connected to a cooling pipe 5, one end of the cooling pipe 5 is fixedly connected to an upper cooling block 6, one side of the upper cooling block 6 is fixedly connected to an upper cooling block 7, the bottom of the upper cooling block 7 is fixedly connected to a cooling pipe 8, the bottom of the cooling pipe 8 is fixedly connected to a lower cooling block 9, and the lower A connecting pipe 10 is fixedly connected to one side of the cooling block 2 9, and an oil pump 11 is fixedly connected to one end of the connecting pipe 10. The input end of the oil pump 11 is fixedly connected to one end of the connecting pipe 10, and the output end of the oil pump 11 is fixedly connected to an oil return pipe 12. One end of the oil return pipe 12 is fixedly connected to the inside of the shell 1. A fan 15 is arranged between the cooling pipe 2 8 and the cooling pipe 1 5. The outer walls of the cooling pipe 2 8 and the cooling pipe 1 5 are both provided with heat dissipation components. The heat dissipation components include fins 14. The fins 14 are fixedly connected to the outer wall of the cooling pipe 2 8. The fins 14 are arranged in a linear array and are fixedly connected to the outer walls of the cooling pipe 2 8 and the cooling pipe 1 5.

[0032] Specifically, in the process of dissipating the heat of the lubricating oil in the housing 1, first, the input end of the oil pump 11 sucks the lubricating oil in the housing 1 through the oil outlet pipe 2, and then the lubricating oil is transported to the filter 3 for filtration. The filter 3 can effectively remove impurities and particulate matter in the lubricating oil, ensure the cleanliness of the lubricating oil, and avoid equipment wear and failure caused by impurities. The filtered lubricating oil enters the lower cooling block 4 and begins its cooling process. In the lower cooling block 4, the lubricating oil further flows into the upper cooling block 6 through the cooling pipe 5. In this process, the design of the cooling pipe plays a key role. The outer walls of the cooling pipe 5 and the cooling pipe 8 are both arranged with a plurality of fins 14. These fins 14 are like fins on a radiator, which greatly increase the contact area between the lubricating oil and the air, thereby improving the heat dissipation efficiency. As the lubricating oil flows, it enters the upper cooling block 7 and enters the lower cooling block 9 through the cooling pipe 8. In this process, the lubricating oil stays on both sides of the cooling tube 2 8 and the cooling tube 1 5, further increasing the heat dissipation area and extending the residence time of the lubricating oil, so that it can more fully exchange heat with the cooling tube, thereby improving the heat dissipation effect. In order to improve the heat dissipation efficiency, the fan 15 plays an important role. It draws in the external air through the fins 14 on the outer wall of the cooling tube 1 5 and blows it to the fins 14 on the outer wall of the cooling tube 2 8. This operation not only accelerates the flow of air, but also enables the air to better pass through the gaps between the fins 14 and take away more heat. After a series of cooling processes, the lubricating oil enters the oil pump 11 through the connecting pipe 10. At this time, the temperature of the lubricating oil has been significantly reduced, achieving the expected heat dissipation effect. Finally, the lubricating oil is pumped out through the output end of the oil pump 11 and returned to the housing 1 through the return oil pipe 12, continuing to provide lubrication and cooling for the normal operation of the equipment.

[0033] Reference Figure 3 and Figure 4 The outer wall of the filter 3 is threadedly connected with a sealing cover 16, the outer wall of the filter 3 is fixedly connected with a fixed block 21 arranged in a ring array, the fixed block 21 is slidably connected to a limit plate 22, one side of the limit plate 22 is fixedly connected with a hemispherical column 23, a telescopic rod 24 is arranged inside the fixed block 21, and a spring 25 is sleeved on the outer wall of the telescopic rod 24. One end of the telescopic rod 24 and the spring 25 are fixedly connected to the other side of the limit plate 22, and the other end of the telescopic rod 24 and the spring 25 are fixedly connected to the inside of the fixed block 21, the filter 3 is fixedly connected with a limit ring 17, the filter 3 is slidably connected with a frame 18, the frame 18 is provided with a slot 20, the frame 18 is fixedly connected with a filter screen 19, the outer wall of the hemispherical column 23 is embedded in the slot 20, and the outer wall of the hemispherical column 23 is slidably connected to the inside of the filter 3;

[0034] Specifically, during the installation of the filter screen 19, first, the sealing cover 16 is disassembled, and then the filter screen 19 is inserted into the filter 3 through the frame 18. After the filter screen 19 is inserted into the filter 3, it is limited by the limit ring 17. The function of the limit ring 17 is to ensure that the position of the filter screen 19 in the filter 3 is stable to prevent it from moving or shaking during operation. Subsequently, in the filter 3, the hemispherical column 23 is embedded in the card slot 20 to achieve fixation. The design of the hemispherical column 23 cleverly utilizes the embedding principle, so that the frame 18 can be firmly fixed in the filter 3. In addition, the hemispherical column 23 is also limited in the fixed block 21 by the limit plate 22, further enhancing its stability and reliability. In the process of the hemispherical column 23 being embedded in the card slot 20, the tension of the spring 25 plays a key role. The tension of the spring 25 can ensure that the hemispherical column 23 is tightly embedded in the card slot 20 and is not easy to slide out. This design not only improves the convenience of installation, but also enhances the durability and safety of the equipment. Finally, the removed sealing cover 16 is reinstalled and tightened.

[0035] Working principle: When the automatic lubrication device of the gear reducer is used, when the filter screen 19 needs to be installed first, the sealing cover 16 is first disassembled, and then the filter screen 19 is inserted into the filter 3 through the frame 18. The filter screen 19 is limited in position by the limit ring 17 in the filter 3 through the frame 18, and then the frame 18 is fixed in the filter 3 by the hemispherical column 23 in the filter 3 being embedded in the card groove 20. The hemispherical column 23 is limited in position in the fixing block 21 by the limit plate 22, and is supported by the tension of the spring 25, so that the hemispherical column 23 is embedded in the card groove 20 and is not easy to slide out. Then the sealing cover 16 is reinstalled and tightened. When the lubricating oil in the housing 1 is dissipated, the input end of the oil pump 11 absorbs the lubricating oil in the housing 1 through the oil outlet pipe 2 The oil enters the filter 3 for filtration and then enters the lower cooling block 4. The lubricating oil enters the upper cooling block 6 through the cooling pipe 5, then enters the upper cooling block 7 and enters the lower cooling block 9 through the cooling pipe 8. A plurality of fins 14 are arranged on the outer walls of the cooling pipe 8 and the cooling pipe 5 to increase the contact area between the lubricating oil and the air and improve the heat dissipation efficiency. Then the fan 15 inhales the external air through the fins 14 on the outer wall of the cooling pipe 5 and blows it to the fins 14 on the outer wall of the cooling pipe 8 to improve the heat dissipation efficiency. The residence time of the lubricating oil on both sides of the cooling pipe 8 and the cooling pipe 5 is increased to increase the heat dissipation area. Then the lubricating oil enters the oil pump 11 through the connecting pipe 10, and then the lubricating oil is pumped out through the output end of the oil pump 11 and returned to the housing 1 through the return oil pipe 12.
