Description
Technical Field
[0001] This invention relates to the field of speed reducer technology, specifically to an ultra-precision speed reducer for industrial robots. Background Technology
[0002] Ultra-precision speed reducers are high-precision, high-rigidity speed reduction devices, mainly used in industrial robots and other precision mechanical equipment to provide precise motion control and torque transmission.
[0003] In the prior art, such as the Chinese patent number CN105952874A, "A planetary reducer", it includes a reducer and a planetary reduction device disposed at the input end of the reducer; the reducer includes a first input shaft, a third-stage center gear and a second-stage center gear connected in series.
[0004] In existing technologies, during operation, the reducer body uses lubricating oil to cool and dissipate the high temperatures generated during operation, maintaining stable operation. However, at the connection between the power input shaft and the main body, due to the reducer's sealing requirements, a seal is used at the connection point. This prevents lubricating oil from reaching the connection point, and because the input shaft rotates at a high speed, the temperature at the connection point is also high. Without the cooling and heat dissipation effect of lubricating oil, the high temperature at the connection point cannot dissipate quickly, leading to excessively high temperatures. This causes the seals at the connection point to age faster or even fail, resulting in poor sealing of the reducer and a decrease in its working performance. Summary of the Invention
[0005] The purpose of this invention is to provide an ultra-precision reducer for industrial robots, addressing the problems mentioned in the background art. Due to the need for sealing in reducers, a seal is used at the connection between the input shaft and the reducer body. This seal prevents lubricating oil from reaching the connection point, and the high speed of the input shaft leads to high temperatures at the connection. Without the cooling and heat dissipation effect of lubricating oil, the high temperature at the connection cannot dissipate quickly, causing accelerated aging of the seal and even damage to the seal. This results in poor sealing of the reducer and a decline in its performance.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultra-precision reducer for industrial robots, comprising a reducer assembly and a control mechanism, wherein a heat dissipation mechanism is fixedly connected to one side of the reducer assembly, a connecting mechanism is installed on one side of the heat dissipation mechanism, a transmission mechanism is installed on one side of the connecting mechanism, and the control mechanism is installed on the surface of the reducer assembly;
[0007] The speed reducer assembly includes a speed reducer body, one end of which is rotatably connected to an input shaft. The heat dissipation mechanism includes a second heat sink, a first annular guide rail, fan blades, and a brush. The second heat sink is fixedly connected to one side of the speed reducer body. The first annular guide rail is fixedly connected to the speed reducer body, and a first annular slider is slidably connected inside the first annular guide rail. Fan blades are fixedly connected to the surface of the first annular slider, and a brush is fixedly connected to the surface of the first annular slider.
[0008] The transmission mechanism includes a drive plate, which is fixedly connected to the input shaft. A driven plate is provided on one side of the drive plate, a slot is provided on one side of the drive plate, and a retaining strip is fixedly connected to one side of the driven plate.
[0009] The connecting mechanism includes a first connecting rod, a second connecting rod, a strip guide rail, a second annular slider, and a second annular slide rail. One end of the first connecting rod is fixedly connected to the side wall of the driven plate, and the other end of the first connecting rod is fixedly connected to an insert rod. One end of the second connecting rod is fixedly connected to the side wall of the first annular slider, and the other end of the second connecting rod is inserted into the insert rod. One end of the strip guide rail is fixedly connected to the main body of the reducer, and a strip slider is slidably connected inside the strip guide rail.
[0010] When the temperature of this device is too high, the input shaft drives the reducer body to run, thereby causing the output shaft to rotate. During the rotation of the input shaft, a large amount of heat is generated at the connection point with the reducer body. The temperature sensor monitors the temperature at this connection point. When the temperature at the connection point exceeds a set value, the temperature sensor transmits a high-temperature signal to the controller. The controller then quickly energizes electromagnets one and two, causing their magnetic ends to generate the same magnetic poles. Electromagnet one then pushes electromagnet two, which in turn moves the fixed frame and the strip slider closer to the transmission mechanism. The strip slider then pushes the driven plate surface... The locking strip on the input shaft engages with the slot on the active plate. Simultaneously, the input shaft drives the active and driven plates to rotate. The rotation of the driven plate causes the first annular slider to rotate, which in turn drives the fan blades to rotate, thus ventilating the surface of the second heat sink and accelerating its heat dissipation efficiency. This rapidly cools the connection between the input shaft and the mounting base, preventing overheating. The ventilation holes on the surface of the second heat sink further accelerate airflow and enhance its heat dissipation speed. As the first annular slider rotates, it also drives a brush to clean the surface of the second heat sink, preventing dust accumulation and ensuring optimal heat dissipation performance.
[0011] Preferably, a mounting base is fixedly connected to the bottom of the reducer body, and multiple heat sinks are fixedly connected to the surface of the reducer body. The multiple heat sinks are evenly distributed on the surface of the reducer body, and an output shaft is rotatably connected to one end of the reducer body.
[0012] Preferably, the surface of the second heat sink is provided with a plurality of heat dissipation holes, which are arranged in a ring on the surface of the second heat sink.
[0013] Preferably, the first annular guide rail is located on the side of the second heat sink, and multiple fan blades are fixedly connected to the surface of the first annular slider, with the multiple fan blades distributed in a ring on the surface of the first annular slider.
[0014] Preferably, a plurality of brushes are fixedly connected to the surface of the first annular slider, and the plurality of brushes are distributed in a ring on the surface of the first annular slider, and the brushes are in contact with the side of the second heat sink.
[0015] Preferably, the active plate has multiple slots on one side, and the multiple slots are evenly distributed on one side of the active plate. The driven plate is fixedly connected to multiple locking strips on one side, and the multiple locking strips are evenly distributed on one side of the driven plate. The locking strips are located inside the slots and engage with the active plate.
[0016] Preferably, one end of the second connecting rod is provided with a socket, and the plug is located inside the socket and is inserted into the second connecting rod. Multiple first connecting rods are fixedly connected to the side wall of the driven plate. The multiple first connecting rods are evenly distributed on the side wall of the driven plate, and the positions of the first connecting rod and the second connecting rod correspond to each other.
[0017] Preferably, one end of the strip slider is fixedly connected to the second annular slider, the second annular slide rail is fixedly connected to one side of the driven plate, and the inside of the second annular slide rail is slidably connected to the second annular slider. Four strip guide rails are provided on one side of the reducer body, and the four strip guide rails are distributed in a rectangular shape on the side of the reducer body.
[0018] Preferably, the control mechanism includes a controller, a temperature sensor, a first electromagnet, and a fixed frame. The controller is fixedly connected to the surface of the reducer body, the temperature sensor is fixedly connected to the reducer body, the first electromagnet is fixedly connected to the surface of the reducer body, the fixed frame is fixedly connected to the strip slider, and a second electromagnet is fixedly connected to the side of the fixed frame.
[0019] Preferably, the temperature sensor is located at the upper part of the connection between the reducer body and the input shaft. The temperature sensor is electrically connected to the controller, the controller is electrically connected to the first electromagnet, and the controller is electrically connected to the second electromagnet. Multiple first electromagnets are provided on one side of the reducer body, and multiple second electromagnets are provided on the surface of the fixing frame. The multiple first electromagnets and the multiple second electromagnets are distributed in a mirror image.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. In this invention, the fixed frame and the strip slider are moved closer to the transmission mechanism by the pushing action of the first electromagnet. The strip slider causes the locking strip on the surface of the driven plate to engage with the locking groove on the surface of the driving plate. At the same time, the input shaft drives the driving plate and the driven plate to rotate. The rotation of the driven plate causes the first annular slider to rotate. Subsequently, the first annular slider drives the fan blades to rotate, thereby ventilating the surface of the second heat sink and accelerating the heat dissipation efficiency of the second heat sink. This allows the connection between the input shaft and the mounting base to be cooled down quickly, preventing the connection from overheating.
[0022] 2. In this invention, the heat dissipation holes on the surface of the second heat sink accelerate the airflow and improve the heat dissipation speed of the second heat sink. When the first annular slider rotates, it will also drive the brush to clean the surface of the second heat sink, so as to prevent dust from adhering to the surface of the second heat sink during use, which would lead to a decrease in the heat dissipation performance of the second heat sink.
[0023] 3. In this invention, the temperature sensor transmits a signal to the controller. At this time, the controller controls the change of the magnetic poles on the surface of the first electromagnet. The first electromagnet attracts the second electromagnet, causing the driven plate to detach from the driving plate. This can reduce the kinetic energy loss of the input shaft during power output and improve the efficiency of kinetic energy transmission. When it is necessary to cool the connection, the heat dissipation mechanism can be directly driven by the input shaft, reducing the use of the power source and reducing the cost of using and maintaining the reducer components.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1
[0034] Reference Figure 1-8 As shown: An industrial robot ultra-precision reducer includes a reducer assembly 1 and a control mechanism 5.

[0035] The reducer assembly 1 includes a reducer body 11, an input shaft 15 rotatably connected to one end of the reducer body 11, and an output shaft 14 rotatably connected to one end of the reducer body 11. The heat dissipation mechanism 2 includes a second heat sink 21, a first annular guide rail 22, fan blades 24, and a brush 25. The second heat sink 21 is fixedly connected to one side of the reducer body 11. The first annular guide rail 22 is fixedly connected to the reducer body 11, and a first annular slider 23 is slidably connected inside the first annular guide rail 22. The fan blades 24 are fixedly connected to the surface of the first annular slider 23, and the brush 25 is fixedly connected to the surface of the first annular slider 23.
[0036] The transmission mechanism 4 includes a drive plate 41, which is fixedly connected to the input shaft 15. A driven plate 43 is provided on one side of the drive plate 41, a slot 42 is provided on one side of the drive plate 41, and a retaining strip 44 is fixedly connected to one side of the driven plate 43.
[0037] The connecting mechanism 3 includes a first connecting rod 31, a second connecting rod 32, a strip guide rail 33, a second annular slider 36, and a second annular slide rail 35. One end of the first connecting rod 31 is fixedly connected to the side wall of the driven plate 43, and the other end of the first connecting rod 31 is fixedly connected to an insert rod 37. One end of the second connecting rod 32 is fixedly connected to the side wall of the first annular slider 23, and the other end of the second connecting rod 32 is inserted into the insert rod 37. One end of the strip guide rail 33 is fixedly connected to the reducer body 11, and a strip slider 34 is slidably connected inside the strip guide rail 33.
[0038] The control mechanism 5 includes a controller 51, a temperature sensor 52, a first electromagnet 53, and a fixing frame 55. The controller 51 is fixedly connected to the surface of the reducer body 11, the temperature sensor 52 is fixedly connected to the reducer body 11, the first electromagnet 53 is fixedly connected to the surface of the reducer body 11, the fixing frame 55 is fixedly connected to the strip slider 34, and a second electromagnet 54 is fixedly connected to the side of the fixing frame 55.
[0039] The working principle of this embodiment is as follows: The input shaft 15 drives the reducer body 11 to operate, thereby causing the output shaft 14 to rotate. During the rotation of the input shaft 15, a large amount of heat is generated at the connection point with the reducer body 11. The temperature sensor 52 monitors the temperature at the connection point. When the temperature at the connection point exceeds a set value, the temperature sensor 52 transmits a high-temperature signal to the controller 51. Then, the controller 51 quickly energizes the first electromagnet 53 and the second electromagnet 54, causing their magnetic ends to generate the same magnetic poles. At this time, the first electromagnet 53 pushes the second electromagnet 54. Driven by the push of the input shaft 3, the fixed frame 55 and the strip slider 34 move towards the side closer to the transmission mechanism 4. Driven by the strip slider 34, the locking strip 44 on the surface of the driven plate 43 engages with the locking groove 42 on the surface of the driving plate 41. At the same time, the input shaft 15 drives the driving plate 41 and the driven plate 43 to rotate. The rotation of the driven plate 43 causes the first annular slider 23 to rotate. Then the first annular slider 23 drives the fan blade 24 to rotate, thereby ventilating the surface of the second heat sink 21, accelerating the heat dissipation efficiency of the second heat sink 21, and rapidly cooling the connection between the input shaft 15 and the mounting base 12 to avoid the connection temperature from being too high.
[0040] The heat dissipation holes 26 on the surface of the second heat sink 21 accelerate air circulation and improve the heat dissipation speed of the second heat sink 21. When the first annular slider 23 rotates, it will drive the brush 25 to clean the surface of the second heat sink 21, so as to prevent dust from adhering to the surface of the second heat sink 21 during use, which would reduce the heat dissipation performance of the second heat sink 21.
[0041] As the driven plate 43 moves closer to the driving plate 41, the insertion rod 37 slides along the insertion hole 38, and the rotational power is stably transmitted to the first annular slider 23 through multiple first connecting rods 31 and second connecting rods 32, making the rotation of the first annular slider 23 more stable.
[0042] When the temperature at the connection drops to the normal value, the temperature sensor 52 transmits a signal to the controller 51. At this time, the controller 51 controls the change of the magnetic poles on the surface of the first electromagnet 53. The first electromagnet 53 then attracts the second electromagnet 54, causing the driven plate 43 to detach from the driving plate 41. This reduces the kinetic energy loss of the input shaft 15 during power output and improves the efficiency of kinetic energy transmission. When it is necessary to cool the connection, the input shaft 15 directly drives the heat dissipation mechanism 2 to operate, reducing the use of the power source and lowering the cost of using and maintaining the reducer assembly 1.

[0044] The reducer assembly 1 includes a reducer body 11, with an input shaft 15 rotatably connected to one end of the reducer body 11. The heat dissipation mechanism 2 includes a second heat sink 21, a first annular guide rail 22, fan blades 24, and a brush 25. The second heat sink 21 is fixedly connected to one side of the reducer body 11. The first annular guide rail 22 is fixedly connected to the reducer body 11, and a first annular slider 23 is slidably connected inside the first annular guide rail 22. Fan blades 24 are fixedly connected to the surface of the first annular slider 23, and a brush 25 is fixedly connected to the surface of the first annular slider 23.

The surface of the first ring slider 23 is fixedly connected with several brushes 25, which are arranged in a ring on the surface of the first ring slider 23. The brushes 25 are in contact with the side of the second heat sink 21.
[0046] The working principle of this embodiment is as follows: The input shaft 15 drives the reducer body 11 to operate, thereby causing the output shaft 14 to rotate. During the rotation of the input shaft 15, a large amount of heat is generated at the connection point with the reducer body 11. The temperature sensor 52 monitors the temperature at the connection point. When the temperature at the connection point exceeds a set value, the temperature sensor 52 transmits a high-temperature signal to the controller 51. Then, the controller 51 quickly energizes the first electromagnet 53 and the second electromagnet 54, causing their magnetic ends to generate the same magnetic poles. At this time, the first electromagnet 53 pushes the second electromagnet 54. Driven by the push of the input shaft 3, the fixed frame 55 and the strip slider 34 move towards the side closer to the transmission mechanism 4. Driven by the strip slider 34, the locking strip 44 on the surface of the driven plate 43 engages with the locking groove 42 on the surface of the driving plate 41. At the same time, the input shaft 15 drives the driving plate 41 and the driven plate 43 to rotate. The rotation of the driven plate 43 causes the first annular slider 23 to rotate. Then the first annular slider 23 drives the fan blade 24 to rotate, thereby ventilating the surface of the second heat sink 21, accelerating the heat dissipation efficiency of the second heat sink 21, and rapidly cooling the connection between the input shaft 15 and the mounting base 12 to avoid the connection temperature from being too high.
[0047] The heat dissipation holes 26 on the surface of the second heat sink 21 accelerate air circulation and improve the heat dissipation speed of the second heat sink 21. When the first annular slider 23 rotates, it will drive the brush 25 to clean the surface of the second heat sink 21, so as to prevent dust from adhering to the surface of the second heat sink 21 during use, which would lead to a decrease in the heat dissipation performance of the second heat sink 21.

Multiple locking strips 44 are fixedly connected to one side of the driven plate 43, and the multiple locking strips 44 are evenly distributed on one side of the driven plate 43. The locking strips 44 are located inside the slots 42 and engage with the driving plate 41. One end of the second connecting rod 32 is provided with an insertion hole 38. 37 is located inside the insertion hole 38 and is inserted into the second connecting rod 32. Multiple first connecting rods 31 are fixedly connected to the side wall of the driven plate 43. The multiple first connecting rods 31 are evenly distributed on the side wall of the driven plate 43. The positions of the first connecting rods 31 and the second connecting rods 32 correspond to each other. One end of the strip slider 34 is fixedly connected to the second annular slider 36. The second annular slide rail 35 is fixedly connected to one side of the driven plate 43, and the inside of the second annular slide rail 35 is slidably connected to the second annular slider 36. Four strip guide rails 33 are provided on one side of the reducer body 11. The four strip guide rails 33 are distributed in a rectangle on the side of the reducer body 11.
[0049] The control mechanism 5 includes a controller 51, a temperature sensor 52, a first electromagnet 53, and a mounting bracket 55. The controller 51 is fixedly connected to the surface of the reducer body 11, the temperature sensor 52 is fixedly connected to the reducer body 11, the first electromagnet 53 is fixedly connected to the surface of the reducer body 11, the mounting bracket 55 is fixedly connected to the strip slider 34, and a second electromagnet 54 is fixedly connected to the side of the mounting bracket 55. The temperature sensor 52 is located above the connection between the reducer body 11 and the input shaft 15. The temperature sensor 52 is electrically connected to the controller 51, the controller 51 is electrically connected to the first electromagnet 53, and the controller 51 is electrically connected to the second electromagnet 54. Multiple first electromagnets 53 are arranged on one side of the reducer body 11, and multiple second electromagnets 54 are arranged on the surface of the mounting bracket 55. The multiple first electromagnets 53 and the multiple second electromagnets 54 are distributed in a mirror image.
[0050] The working principle of this embodiment is as follows: The input shaft 15 drives the reducer body 11 to run, thereby causing the output shaft 14 to rotate. During the rotation of the input shaft 15, a large amount of heat is generated at the connection point with the reducer body 11. The temperature sensor 52 monitors the temperature at this connection point. When the temperature at the connection point exceeds a set value, the temperature sensor 52 transmits a high-temperature signal to the controller 51. Then, the controller 51 quickly energizes the first electromagnet 53 and the second electromagnet 54, causing their magnetic ends to generate the same magnetic poles. Electromagnet 53 pushes electromagnet 54. Under the pushing action of electromagnet 53, the fixed frame 55 and the strip slider 34 move towards the side closer to the transmission mechanism 4. Under the pushing action of the strip slider 34, the locking strip 44 on the surface of the driven plate 43 engages with the locking groove 42 on the surface of the driving plate 41. When the driven plate 43 moves closer to the driving plate 41, the insertion rod 37 slides along the insertion hole 38. Through multiple connecting rods 31 and 32, the rotational power is stably transmitted to the annular slider 23, making the rotation of the annular slider 23 more stable.
[0051] When the temperature at the connection drops to the normal value, the temperature sensor 52 transmits a signal to the controller 51. At this time, the controller 51 controls the change of the magnetic poles on the surface of the first electromagnet 53. The first electromagnet 53 then attracts the second electromagnet 54, causing the driven plate 43 to detach from the driving plate 41. This reduces the kinetic energy loss of the input shaft 15 during power output and improves the efficiency of kinetic energy transmission. When it is necessary to cool the connection, the input shaft 15 directly drives the heat dissipation mechanism 2 to operate, reducing the use of the power source and lowering the cost of using and maintaining the reducer assembly 1.
[0052] The device's operation and working principle are as follows: The input shaft 15 drives the reducer body 11, causing the output shaft 14 to rotate. During this rotation, a large amount of heat is generated at the connection point between the input shaft 15 and the reducer body 11. The temperature sensor 52 monitors this temperature. When the temperature exceeds a set value, the temperature sensor 52 transmits a high-temperature signal to the controller 51. The controller 51 then quickly energizes electromagnets 53 and 54, causing them to generate identical magnetic poles. At this time, electromagnet 53 will push electromagnet 54. Under the pushing action of electromagnet 53, the fixed frame 55 and the strip slider 34 will move towards the side closer to the transmission mechanism 4. Under the pushing action of the strip slider 34, the locking strip 44 on the surface of the driven plate 43 will engage with the locking groove 42 on the surface of the driving plate 41. At the same time, the input shaft 15 will drive the driving plate 41 and the driven plate 43 to rotate. Under the rotation action of the driven plate 43, the first annular slider 23 will rotate. Then the first annular slider 23 will drive the fan blade 24 to rotate, thereby ventilating the surface of the second heat sink 21.
[0053] The heat dissipation holes 26 on the surface of the second heat sink 21 accelerate the air circulation and improve the heat dissipation speed of the second heat sink 21. When the first annular slider 23 rotates, it will drive the brush 25 to clean the surface of the second heat sink 21.
[0054] When the temperature at the connection point drops to the normal value, the temperature sensor 52 transmits a signal to the controller 51. At this time, the controller 51 controls the change of the magnetic poles on the surface of the first electromagnet 53. The first electromagnet 53 then attracts the second electromagnet 54, causing the driven plate 43 to detach from the driving plate 41.
