[0002] A speed reducer mainly consists of main components such as gears (worm gears), a housing, bearings, etc. It plays a role in matching speeds and transmitting torques between a prime mover and a working machine or an actuator.

Specific embodiments

[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 Figure 1 - Figure 8As shown in the figure, the present invention provides an explosion-proof temperature control device for a hollow shaft reducer, which includes a motor 1. A rotating shaft one 2 is fixedly installed at the output end of the motor 1. A sealing ring one 3 is movably sleeved on the outer surface wall of the rotating shaft one 2. A protective shell 4 is adhered to the outer surface wall of the sealing ring one 3. An air outlet valve 5 is fixedly communicated with the top of the protective shell 4. A group of heat sinks 6 are fixedly inserted into the inner surface wall of the protective shell 4. A reducer body 7 is fixedly inserted between the inner surface walls of the group of heat sinks 6. A temperature sensor 8 is fixedly installed on one side of the outer wall of the reducer body 7, and the outer surface wall of the rotating shaft one 2 is fixedly inserted into the inside of the reducer body 7. A sealing ring two 9 is adhered to the outer surface wall of the reducer body 7, and the outer surface wall of the sealing ring two 9 is adhered to the inner surface wall of the protective shell 4. A sprocket one 10 is fixedly sleeved on the outer surface wall of the rotating shaft one 2. A chain 11 is movably sleeved on the outer surface wall of the sprocket one 10. A sprocket two 12 is movably inserted into the inner surface wall of the chain 11. A rotating shaft two 13 is fixedly inserted into the inner surface wall of the sprocket two 12. A housing 14 is fixedly installed at the bottom of the protective shell 4. A group of shaft holes one 15 are opened on the outer surface wall of the housing 14, and the outer surface wall of the rotating shaft two 13 is movably inserted between the inner surface walls of the group of shaft holes one 15. An air pipe 16 is fixedly communicated with the bottom of the protective shell 4, and the outer surface wall of the air pipe 16 is fixedly inserted into the inside of the housing 14. A rotating frame 17 is fixedly sleeved on the outer surface wall of the rotating shaft two 13. Two groups of shaft holes two 18 are opened on the outer surface wall of the rotating frame 17. A rotating shaft three 19 is movably inserted between the inner surface walls of the two groups of shaft holes two 18. An extrusion roller 20 is fixedly sleeved on the outer surface wall of each of the two rotating shafts three 19, and the outer surface walls of the two extrusion rollers 20 are in contact with the outer surface wall of the air pipe 16. A treatment box 21 is fixedly installed at the bottom of the protective shell 4. An air inlet valve 29 is fixedly communicated with one side of the outer wall of the treatment box 21.

[0022] In this embodiment, after the motor 1 starts, it drives the first rotating shaft 2 at the output end to start rotating. At this time, the speed reducer body 7 utilizes the principle of gear transmission to reduce the speed of the high-speed rotating motion of the first rotating shaft 2 and increase the torque. The two sealing rings can cooperate with the protective housing 4 to prevent impurities such as external dust and water vapor from entering the speed reducer body 7, which helps to maintain the cleanliness of the speed reducer and extend the service life of the equipment. As the speed reducer body 7 starts to work, the internal structure will continuously increase in temperature due to reasons such as friction and overload. When the first rotating shaft 2 rotates, it drives the first sprocket 10 fixedly sleeved on the outer surface wall to start rotating. The first sprocket 10 causes the chain 11 sleeved on the outer surface wall to start moving. The movement of the chain 11 drives the second sprocket 12 at the bottom to rotate synchronously. The second sprocket 12 causes the second rotating shaft 13 inserted inside to rotate inside the housing 14. At this time, the second rotating shaft 13 starts to drive the rotating frame 17 fixedly sleeved on the outer surface wall to rotate inside the housing 14. When the rotating frame 17 rotates, it drives the extrusion roller 20 to rotate by means of the third rotating shaft 19 inserted inside. The extrusion roller 20 alternately squeezes and releases the elastic air pipe 16. When the extrusion roller 20 squeezes the air pipe 16, the air pipe 16 is compressed, the internal space decreases, so that the gas is extruded and pushed to the front end of the air pipe 16 and transported into the protective housing 4. As the extrusion roller 20 continues to rotate, the extruded area of the air pipe 16 gradually returns to its original state, and a negative pressure area is formed in the processing box 21, attracting external cold air to enter the air pipe 16 through the intake valve 29 and be transported into the protective housing 4. When the cold air enters the inside of the processing box 21, it will take away the heat on the surface of the speed reducer body 7. A group of heat dissipation fins 6 installed on the outer surface wall of the speed reducer body 7 can effectively increase the heat dissipation area of the speed reducer body 7, thereby improving the heat exchange efficiency with the external air and further preventing the equipment from being damaged due to overheating. The gas that has absorbed heat and increased in temperature will be discharged through the outlet valve 5 under the action of pressure. By quickly reducing the temperature of the speed reducer body 7, the risk of explosion accidents is greatly reduced, and equipment damage caused by too high temperature is avoided, thus ensuring the stable operation of the speed reducer. When the temperature control device cannot reduce the temperature of the speed reducer body 7, the temperature sensor 8 will detect that the temperature of the speed reducer body 7 is too high. At this time, it will send a signal in time to automatically cut off the power supply of the motor 1, further improving the safety of the work.

[0023] Embodiment 2: According to Figure 1 - Figure 2 、 Figure 5 and Figure 7 - Figure 8As shown in the figure, a processing box 21 is fixedly installed at the bottom of the protective case 4. A set of third shaft holes 22 are formed in the outer surface wall of the processing box 21, and a set of fourth shaft holes 23 are formed in the outer surface wall of the processing box 21. Two mounting brackets 24 are fixedly inserted into the inner surface wall of the processing box 21. A set of springs 25 are fixedly installed on one side of the outer walls of the two mounting brackets 24. An activated carbon adsorption net 26 is fixedly installed between the outer surfaces of one of the two sets of springs 25, and the activated carbon adsorption net 26 is movably inserted into the interior of the processing box 21. A metal filter net 27 is fixedly installed between the outer surfaces of the other set of the two sets of springs 25, and the metal filter net 27 is movably inserted into the interior of the processing box 21. A water absorption plate 28 is fixedly inserted into the inner surface wall of the processing box 21.

[0024] In this embodiment, when the outside air enters the interior of the processing box 21, the water absorption plate 28 can absorb the moisture in the air, preventing the humidity inside the protective case 4 from being too high, which may cause problems such as short circuits in the circuit and corrosion of components in the speed reducer body 7. The metal filter net 27 can filter impurities such as dust and particulate matter in the air, preventing relevant impurities from accumulating inside the protective case 4, affecting the heat dissipation effect of the speed reducer body 7, and preventing impurities from entering the interior of the speed reducer body 7, resulting in damage to the speed reducer body 7. The activated carbon adsorption net 26 can not only intercept fine particulate matter, but also effectively adsorb harmful gases in the air, reducing the erosion and damage of these harmful substances to the internal components of the speed reducer. At the same time, it can also reduce the concentration of flammable and explosive gases, thereby reducing the risk of explosion and fire.

[0025] Embodiment 3: According to Figure 1 - Figure 2 、 Figure 5 and Figure 7 - Figure 8As shown in the figure, a processing box 21 is fixedly installed at the bottom of the protective case 4. A set of third shaft holes 22 are formed in the outer surface wall of the processing box 21, and a set of fourth shaft holes 23 are formed in the outer surface wall of the processing box 21. Two mounting brackets 24 are fixedly inserted into the inner surface wall of the processing box 21. A set of springs 25 are fixedly installed on one side of the outer walls of the two mounting brackets 24. An activated carbon adsorption net 26 is fixedly installed between the outer surfaces of one of the two sets of springs 25, and the activated carbon adsorption net 26 is movably inserted into the interior of the processing box 21. A metal filter net 27 is fixedly installed between the outer surfaces of the other set of the two sets of springs 25, and the metal filter net 27 is movably inserted into the interior of the processing box 21. A water absorption plate 28 is fixedly inserted into the inner surface wall of the processing box 21. An air inlet valve 29 is fixedly communicated with one side of the outer wall of the processing box 21. A set of fourth rotating shafts 30 are movably inserted into the inner surface walls of the set of fourth shaft holes 23. A set of first gears 31 are fixedly sleeved on the outer surfaces of the set of fourth rotating shafts 30. A set of fan blades 32 are fixedly sleeved on the outer surfaces of the set of fourth rotating shafts 30. A set of fifth rotating shafts 33 are movably inserted into the inner surface walls of the set of third shaft holes 22. A set of second gears 34 are fixedly sleeved on the outer surfaces of the set of fifth rotating shafts 33, and the outer surfaces of the set of second gears 34 are meshed and connected with the inner surfaces of the first gears 31. A set of rubber knocking balls 35 are fixedly sleeved on the outer surfaces of the set of fifth rotating shafts 33.

[0026] In this embodiment, when the air circulates inside the processing box 21, it will drive the fan blades 32 to start rotating. At this time, the fourth rotating shafts 30 inside the fan blades 32 will rotate inside the fourth shaft holes 23 accordingly, and drive the first gears 31 fixedly sleeved on the outer surfaces to start rotating. The second gears 34 meshed and connected with the first gears 31 will rotate accordingly, driving the fifth rotating shafts 33 inside to start rotating inside the third shaft holes 22. When the fifth rotating shafts 33 rotate, they will start to drive the rubber knocking balls 35 on the outer surfaces to rotate, making them continuously knock on the surfaces of the metal filter net 27 and the activated carbon adsorption net 26, and cooperate with the springs 25, so that the metal filter net 27 and the activated carbon adsorption net 26 vibrate continuously, removing some of the dust and particulate matter attached to the surfaces, thereby restoring their filtering performance, preventing the filtering effect of the metal filter net 27 and the activated carbon adsorption net 26 from being affected due to excessive accumulation of surface pollutants, and prolonging the service life of the device.

[0027] The working principle of the entire mechanism is as follows: When the motor 1 starts, the rotating shaft 2 at its output end immediately begins to rotate. This rotational movement is transmitted through the gear transmission system inside the reducer body 7, achieving a reduction in high-speed rotational speed and an increase in torque. During this process, the two sealing rings cooperate closely with the protective shell 4, effectively blocking the entry of external impurities such as dust and moisture into the interior of the reducer body 7. As the reducer body 7 starts and operates, the temperature inside its internal structure gradually rises due to factors such as friction and overload. At this time, the continuous rotation of the rotating shaft 2 drives the sprocket 10 fixedly sleeved on the outer surface to rotate. The rotation of the sprocket 10 further drives the chain 11 sleeved on the outer surface to start moving. The movement of the chain 11 causes the sprocket 12 at the bottom to rotate synchronously. The rotational movement of the sprocket 12 drives the rotating shaft 13 inserted inside to rotate within the outer shell 14. The rotation of the rotating shaft 13 further drives the rotating frame 17 fixedly sleeved on the outer surface to rotate within the outer shell 14. When the rotating frame 17 rotates, it drives the rotation of the extrusion roller 20 through the rotating shaft 19 inserted inside. During the rotation of the extrusion roller 20, it alternately squeezes and releases the elastic air tube 16. When the extrusion roller 20 squeezes the air tube 16, the air tube 16 is compressed, and the internal space decreases, thereby squeezing out the gas and pushing it towards the front end of the air tube 16, and finally delivering the gas into the protective shell 4. As the extrusion roller 20 continues to rotate, the squeezed area of the air tube 16 gradually returns to its original state. At this time, a negative pressure area is formed inside the treatment box 21. This negative pressure area has a strong attraction force, which can attract external cold air to enter the treatment box 21 through the intake valve 29. When the external air flows into the treatment box 21, the water absorption plate 28 will effectively absorb the moisture in the air, ensuring that the humidity inside the protective shell 4 remains at an appropriate level. At the same time, the metal filter net 27 will finely filter out impurities such as dust and particulate matter in the air, preventing these impurities from accumulating inside the protective shell 4 and thus affecting the heat dissipation performance of the reducer body 7. It can effectively prevent impurities from invading the interior of the reducer body 7 and prevent equipment damage caused thereby. In addition, the activated carbon adsorption net 26 not only has the ability to intercept fine particulate matter but also can efficiently adsorb harmful gases in the air, significantly reducing the erosion and damage of these harmful substances to the internal components of the reducer. When the air circulates inside the treatment box 21, it drives the fan blade 32 to rotate, and then drives the rotating shaft 4 inside to rotate within the shaft hole 23. As the rotating shaft 4 rotates, the gear 1 fixedly installed on its outer surface also starts to rotate and interacts with the meshing gear 4, causing the internal rotating shaft 3 to rotate within the shaft hole 22. This series of actions causes the rubber knocking ball 5 on the outer surface of the rotating shaft 3 to continuously rotate and knock on the surfaces of the metal filter net 27 and the activated carbon adsorption net 26. With the cooperation of the spring 25, this knocking causes the metal filter net 27 and the activated carbon adsorption net 26 to vibrate, effectively removing the dust and particulate matter attached to their surfaces, thereby restoring and maintaining their filtering performance.To avoid the decline in filtration efficiency caused by the accumulation of pollutants, thereby extending the service life of the device, the treated air is then conveyed into the protective housing 4 through the air pipe 16. When the cold air enters the treatment box 21, it will carry away the heat on the surface of the reducer body 7. To improve the heat dissipation efficiency, a set of heat sinks 6 are installed on the outer wall of the reducer body 7. These heat sinks 6 effectively increase the heat dissipation area of the reducer and improve the heat exchange efficiency with the outside air. As the heat is absorbed, the gas temperature rises and is discharged through the air outlet valve 5 under the action of pressure. This process rapidly reduces the temperature of the reducer body 7, greatly reduces the risk of explosion accidents, and avoids equipment damage caused by excessive temperature. When the temperature control device fails to effectively reduce the temperature of the reducer body 7, the temperature sensor 8 will timely detect the situation of excessive temperature and send a signal to automatically cut off the power supply of the motor 1 to further ensure the safety of operation.,

[0028] The wiring diagram of the motor 1 and the temperature sensor 8 in the present invention belongs to the common knowledge in the art, and its working principle is already a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 1 and the temperature sensor 8 will not be explained in detail anymore.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
