Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology, and more specifically to a high-efficiency heat dissipation device for a planetary reducer. Background Art

[0002] A planetary reducer is a power transmission device that reduces the speed of a motor while increasing the output torque. It includes bearings, planetary gears, a sun gear, and an inner ring gear. The gear with a fixed axis is called the center gear or sun gear. There is a gear with a variable axis next to the sun gear, that is, a gear that rotates and revolves around itself, called a planetary gear. The planetary gear has a supporting component called a planetary carrier, which transmits power to the shaft through the planetary carrier and then to other gears. They consist of a group of several gears to form a gear train.

[0003] Since the planetary reducer is in a closed reducer, each pair of gears will generate heat when they mesh and rub against each other. As the running time increases, the temperature inside the reducer case gradually increases, causing the planetary reducer to wear. The commonly used heat dissipation devices for planetary reducers are to add heat sinks outside the case to absorb the heat generated by the friction of the gear meshing, and then allow the air to circulate naturally for heat dissipation, or to add fans to the inside of the planetary reducer for heat dissipation and install serpentine water pipes in its oil pool with cooling water flowing through the pipes. The cooling water takes away part of the heat of the lubricating oil, thereby reducing the temperature inside the planetary reducer and dissipating the heat of the planetary reducer.

[0004] The shortcomings of the existing heat dissipation device of a planetary reducer:

[0005] First, the above-mentioned heat dissipation device is equipped with a serpentine water pipe in its oil pool, and cooling water is passed through the pipe. The cooling water takes away part of the heat of the lubricating oil, thereby reducing the temperature inside the planetary reducer. However, this method has low cooling efficiency, and there is a water pipe inside the oil pool. When the planetary reducer is working, it is easy to cause friction damage to the water pipe, causing water to overflow the water pipe into the oil pool, thereby damaging the planetary reducer.

[0006] Secondly, the heat dissipation device is equipped with a serpentine water pipe in its oil pool, and cooling water flows in the pipe. The cooling water takes away part of the heat of the lubricating oil, thereby reducing the temperature inside the planetary reducer. However, the lubricating oil has an optimum temperature range when working. When it is lower than the optimum range, the fluidity of the lubricating oil is poor and strong lubrication is difficult. When it is higher than the optimum range, the internal bearing cannot be cooled, and the bearing is prone to aging, thereby reducing its service life. Summary of the invention

[0012] Furthermore, the constant temperature heat dissipation device includes a constant temperature protective layer, a switch hole is opened on the top of the constant temperature protective layer, a first cooling pipe is fixedly connected to the inner wall of the constant temperature protective layer, one end of the first cooling pipe is fixedly connected to the first connecting pipe, and one end of the first connecting pipe is fixedly connected to the second cooling pipe.

[0013] Furthermore, the cooling switch includes a switch body, the bottom of the switch body is fixedly connected to a switch fixing column, the bottom of the switch fixing column is fixedly connected to a switch assembly, and the bottom of the switch assembly is movably connected to a second connecting pipe.

[0014] Furthermore, the constant temperature protection layer includes a phase change material heat storage layer, one side of the phase change material heat storage layer is fixedly connected to a vacuum insulation layer, and one side of the vacuum insulation layer is fixedly connected to a copper-plated heat reflection layer.

[0015] Furthermore, the input shaft device comprises an input shaft body, an inner wall of the input shaft body is provided with an input slot, an outer wall of the input shaft body is fixedly sleeved with an input retaining ring, and an outer wall of the input retaining ring is fixedly connected with an input blade.

[0016] Furthermore, the sizes of the three slots on the surfaces of the first rotating plate and the second rotating plate are adapted to the sizes of the planetary rotating shafts.

[0017] Furthermore, one end of the output shaft body is connected to the second rotating shaft, the output slot is connected to the output port of the machine, the input slot is connected to the first rotating shaft, and the other end of the input shaft body is connected to the output port of the machine.

[0018] Technical effects and advantages of the present invention:

[0019] 1. The present invention is provided with an output shaft device, a constant temperature heat dissipation device, and an input shaft device. When the machine drives the input shaft body to start working, the input shaft body drives the input retaining ring to rotate the input fan blades to dissipate heat for the planetary reduction device, and the output shaft body drives the output retaining ring to rotate the output fan blades to dissipate heat for the planetary reduction device. At the same time, the constant temperature fixing device is also driven to rotate, so that the constant temperature heat dissipation device rotates together with the input shaft body, thereby rotating the coolant inside the first cooling pipe, the first connecting pipe, and the second cooling pipe, thereby fully absorbing the heat generated by the meshing friction of the gears when the planetary reduction device is working, thereby increasing the heat dissipation efficiency of the planetary reduction device when working.

[0020] 2. The present invention is provided with a constant temperature heat dissipation device. When the first cooling tube, the first connecting tube and the second cooling tube rotate with the input shaft body, the coolant inside them will sway and collide with the phase change material heat storage layer, so that the molecules in the phase change material of the phase change material heat storage layer collide and move, and then change from solid to liquid to absorb heat. At the same time, the vacuum insulation layer performs vacuum insulation on the heat absorbed by the phase change material to reduce heat conduction. The copper-plated heat reflection layer reflects the heat radiation generated by the phase change material, further reducing the heat loss. When the planetary reduction device changes from high-speed operation to slow operation, the heat generated by the meshing of its gears cannot make the internal lubricating oil reach the optimum temperature. At this time, the heat absorbed by the phase change material of the phase change material heat storage layer will be conducted to the coolant inside the first cooling tube, the first connecting tube and the second cooling tube, and then conducted to the outer layer of the planetary reduction device, maintaining its constant temperature, preventing the lubricating oil temperature from being too high or too low, reducing the fluidity of the lubricating oil, or causing the lubricating oil to be esterified and unable to be used, preventing machine aging, and increasing the service life of the machine.

[0034] It needs to be further explained in this embodiment that the output shaft body 31 is connected to the second rotating shaft 46, and the output card slot 32 is connected to the output port of the machine. The output shaft body 31 is driven to rotate by the operation of the machine, so that the output shaft body 31 drives the output clamping ring 33 to rotate, and then the output fan blades 34 are rotated to dissipate heat for the planetary reduction device 4, thereby increasing the heat dissipation efficiency of the planetary reduction device 4.

[0037] Reference Figure 3 and Figure 4 The planetary reduction body 44 comprises a planet carrier 4401, the inner wall of the planet carrier 4401 is fixedly connected with a gear ring 4402, the inner wall of the gear ring 4402 is movably connected with a planetary wheel 4403, the inner wall of the planetary wheel 4403 is movably connected with a planetary rotating column 4404, the inner wall of the planetary rotating column 4404 is movably connected with a planetary rotating shaft 4405, the outer wall of the planetary rotating shaft 4405 is movably sleeved with a planetary ring 4406, the outer wall of the planetary wheel 4403 is movably connected with a sun wheel 4407, and the inner wall of the sun wheel 4407 is fixedly connected with a sun rotating shaft 4408;

[0038] It needs to be further explained in this embodiment that the three slots on the surface of the first rotating plate 43 and the second rotating plate 45 are adapted to the size of the planetary rotating shaft 4405. The three planetary rotating shafts 4405 are driven to rotate by the rotation of the first rotating plate 43, and then the planetary rotating column 4404 and the planetary wheel 4403 are driven to rotate in turn by the planetary rotating shaft 4405. The sun wheel 4407 and the sun rotating shaft 4408 are driven to rotate in turn by the rotation of the three planetary wheels 4403, thereby adjusting the rotation speed of the machine motor and reducing the energy loss of the machine.

[0039] Reference Figure 5 , Figure 6 , Figure 7The constant temperature heat dissipation device 5 includes a constant temperature protection layer 51, the constant temperature protection layer 51 includes a phase change material heat storage layer 5101, a vacuum insulation layer 5102 is fixedly connected to one side of the phase change material heat storage layer 5101, a copper-plated heat reflection layer 5103 is fixedly connected to one side of the vacuum insulation layer 5102, a switch hole 52 is opened on the top of the copper-plated heat reflection layer 5103, a first cooling pipe 53 is fixedly connected to the outer wall of the phase change material heat storage layer 5101, a first connecting pipe 54 is fixedly connected to one end of the first cooling pipe 53, and a second cooling pipe 55 is fixedly connected to one end of the first connecting pipe 54, and a cooling switch 6 includes a switch body 61, a switch fixing column 62 is fixedly connected to the bottom of the switch body 61, a switch assembly 63 is fixedly connected to the bottom of the switch assembly 63, and a second connecting pipe 64 is movably connected to the bottom of the switch assembly 63;

[0040] As further explained in this embodiment, the switch body 61 is twisted to make the switch fixing column 62 drive the switch assembly 63 to rotate and separate from the second connecting tube 64, and then coolant is added to the second connecting tube 64. When the coolant fills the first cooling tube 53, the first connecting tube 54, and the second cooling tube 55, the coolant can be tightened and closed, and the constant temperature heat dissipation device 5 rotates together with the input shaft body 81, thereby rotating the coolant inside the first cooling tube 53, the first connecting tube 54, and the second cooling tube 55, thereby fully absorbing the heat generated by the gear meshing friction when the planetary reduction device 4 is working, thereby increasing the heat dissipation efficiency of the planetary reduction device 4 when working. At the same time, when the first cooling tube 53, the first connecting tube 54, and the second cooling tube 55 rotate with the input shaft body 81, the coolant inside them will collide with the phase change material heat storage layer 5101 when it shakes, causing the phase change material heat storage layer 5101 to rotate. The molecules in the phase change material collide and move, and then change from solid to liquid to absorb heat. At the same time, the vacuum insulation layer 5102 performs vacuum insulation on the heat absorbed by the phase change material to reduce heat conduction. The copper-plated heat reflection layer 5103 reflects the thermal radiation generated by the phase change material, further reducing heat loss. When the planetary reduction device 4 changes from high-speed operation to slow operation, the heat generated by the gear meshing cannot make the internal lubricating oil reach the optimal temperature. At this time, the heat absorbed by the phase change material of the phase change material heat storage layer 5101 will be conducted to the coolant inside the first cooling pipe 53, the first connecting pipe 54, and the second cooling pipe 55, and then conducted to the outer layer of the planetary reduction device 4 to maintain its constant temperature, prevent the lubricating oil temperature from being too high or too low, reduce the fluidity of the lubricating oil, or cause the lubricating oil to esterify and become unusable, prevent machine aging, and increase the service life of the machine.

[0042] It needs to be further explained in this embodiment that the input card slot 82 is connected to the first rotating shaft 42, and the other end of the input shaft body 81 is connected to the output port of the machine. The input shaft body 81 is driven to rotate by the operation of the machine, so that the input shaft body 81 drives the input retaining ring 83 to rotate, and then the input fan blades 84 are rotated to dissipate heat for the planetary reduction device 4, thereby further increasing the heat dissipation efficiency of the planetary reduction device 4.

[0043] Working principle of the present invention:

[0044] S1. The user first connects the input shaft body 81 to the input port of the machine, connects the input card slot 82 to the first rotating shaft 42, and then connects the output card slot 32 to the output port of the machine, and then twists the switch body 61 to make the switch fixing column 62 drive the switch assembly 63 to rotate and separate from the second connecting tube 64, and then add coolant into the second connecting tube 64. When the coolant fills the first cooling tube 53, the first connecting tube 54, and the second cooling tube 55, they can be tightened and closed. When the machine starts working, it drives the input shaft body 81 to start rotating, and the input shaft body 81 then drives the first rotating shaft 42 to rotate. The first rotating shaft 42 is engaged and rotated with the slot hole inside the first rotating plate 43. The three holes on the surface of the first rotating plate 43 are engaged and rotated with the three planetary rotating shafts 4405. The three planetary rotating shafts 4405 are driven to rotate through the rotation of the first rotating plate 43, and then the planetary rotating column 4404 and the planetary wheel 4403 are driven to rotate in turn through the planetary rotating shaft 4405, and the rotation of the three planetary wheels 4403 drives the solar The wheel 4407 and the sun shaft 4408 rotate, so that the sun shaft 4408 is connected and rotated with the card slot inside the second rotating plate 45, and then connected with the output shaft body 31 through the slot hole on the inner wall of the second rotating shaft 46. At the same time, the outer wall of the output shaft body 31 is movably connected with the input protective shell 47, thereby driving the output shaft body 31 to rotate. When the machine drives the input shaft body 81 to start working, the input retaining ring 83 is driven by the input shaft body 81 to rotate the input fan blades 84 to dissipate heat for the planetary reduction device 4, and the output retaining ring 33 is driven by the output shaft body 31 to rotate the output fan blades 34 to dissipate heat for the planetary reduction device 4. At the same time, the constant temperature fixing device 7 is also driven to rotate, so that the constant temperature heat dissipation device 5 rotates together with the input shaft body 81, thereby rotating the coolant inside the first cooling pipe 53, the first connecting pipe 54, and the second cooling pipe 55, thereby fully absorbing the heat generated by the gear meshing friction when the planetary reduction device 4 is working, thereby increasing the heat dissipation efficiency of the planetary reduction device 4 when working.

[0045] S2. When the first cooling tube 53, the first connecting tube 54, and the second cooling tube 55 rotate with the input shaft body 81, the coolant inside them will collide with the phase change material heat storage layer 5101 when shaking, so that the molecules in the phase change material of the phase change material heat storage layer 5101 collide and move, and then change from solid to liquid to absorb heat. At the same time, the vacuum insulation layer 5102 performs vacuum insulation on the heat absorbed by the phase change material to reduce heat conduction, and the copper-plated heat reflection layer 5103 reflects the heat radiation generated by the phase change material, further reducing the heat loss. When the planet decelerates When the device 4 changes from high-speed operation to slow operation, the heat generated by the meshing of its gears cannot make the internal lubricating oil reach the optimal temperature. At this time, the heat absorbed by the phase change material of the phase change material heat storage layer 5101 will be transferred to the coolant inside the first cooling tube 53, the first connecting tube 54, and the second cooling tube 55, and then transferred to the outer layer of the planetary reduction device 4 to maintain its constant temperature, prevent the lubricating oil temperature from being too high or too low, reduce the fluidity of the lubricating oil, or cause the lubricating oil to esterify and become unusable, prevent bearing aging, and increase the service life of the bearing.
