Description

Technical Field

[0001] This application relates to the field of servo motors, and in particular to a high-power servo motor with high stability. Background Technology

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. Servo motors can control speed and position with very high accuracy. They can convert voltage signals into torque and speed to drive the controlled object. Compared with single-machine asynchronous motors, servo motors have three significant characteristics: large starting torque, wide operating range, and no self-rotation phenomenon.

[0003] However, due to the severe vibrations that occur during the operation of servo motors, their stability will be affected over time. The lack of shock absorption and buffering mechanisms is a significant issue. Furthermore, the presence of liquids such as machine oil and lubricating oil inside the servo motor may cause these liquids to solidify in cold weather, affecting the normal operation of the motor and potentially leading to motor failure and even its scrapping.

[0004] Therefore, there is an urgent need for a high-power servo motor with high stability. Summary of the Invention

[0005] The purpose of this application is to solve the problem of unstable operation of servo motors and to provide a high-power servo motor with high stability compared with the prior art. The motor includes a motor body, a drive shaft fixedly connected to the output end of the motor body, a rectangular frame slidably connected to the outer end of the motor body, a plurality of evenly distributed liquid storage bladders fixedly connected to the inner wall of the rectangular frame, a plurality of right-angle plates fixedly connected to the outer end of the rectangular frame, a temperature control box fixedly connected to the rectangular frame through the right-angle plates, an electromagnet sleeved on the outer wall of the drive shaft, a turntable fixedly connected to the outer wall of the electromagnet, a plurality of evenly distributed right-angle rods detachably connected to the side end of the turntable, a driven plate provided on the outer side of the temperature control box, one end of each of the plurality of right-angle rods fixedly connected to the outer end of the driven plate, and a driven shaft fixedly connected to one end of the driven plate.

[0006] The temperature control chamber includes an insulated chamber made of heat-insulating material. Multiple elastic bladders are installed inside the insulated chamber. One end of a driven shaft extends through the insulated chamber, and multiple stirring rods are fixedly connected to the outer end of the driven shaft. A heat-conducting plate is embedded in the outer end of the insulated chamber near the motor body. One side of the heat-conducting plate extends through the interior of the insulated chamber, and the other side contacts the outer end of the motor body. Multiple leak-proof holes with sealing rings are opened at the outer end of the insulated chamber. A connecting pipe is fixedly connected to the inner wall of each leak-proof hole. Multiple liquid storage bladders are fixedly connected to and communicate with the elastic bladders through the connecting pipes. By configuring the liquid storage bladders and the temperature control chamber, when the motor body vibrates, it squeezes the liquid storage bladders, sending the liquid inside to the elastic bladders inside the temperature control chamber. On the one hand, the liquid pressure generated during the process provides a comprehensive buffering effect on the motor body, effectively solving the problem of damage to the motor body caused by severe vibration and affecting its operational stability. On the other hand, the heat generated during the motor operation is absorbed and stored through the heat-conducting plate and the heat storage liquid. When the heat-conducting liquid comes into contact with the heat storage liquid, it can heat it, thereby heating and keeping the motor body warm when it returns to the outer surface of the motor body, reducing heat loss from the outside of the motor body, reducing its failure rate, and ensuring its operational stability. Finally, by replacing the heat storage liquid with coolant and turning on the cooling fins, the motor body can be effectively cooled, thus increasing the versatility of the device and making it usable in both winter and summer.

[0007] Furthermore, the reservoir is made of rubber and is connected to the outer end of the motor body. The connecting tube is made of inelastic soft material, and the inside of the reservoir is filled with heat-conducting fluid.

[0008] Furthermore, the turntable is made of iron, and an iron plate is fixedly connected to one end of the right-angle rod near the turntable. One end of the electromagnet is connected to a controller for electrical signals.

[0009] Furthermore, a waterproof bearing is fixedly connected between the outer side of the driven shaft and the inner wall of the insulation box, and the insulation box is cylindrical in shape.

[0010] Furthermore, the interior of the insulated box is filled with thermal storage oil, with a filling rate of 60-90%.

[0011] Furthermore, the right-angle rod, driven plate, and driven shaft are all made of lightweight materials, and the bottom of the insulated box has a liquid outlet hole, with a sealing valve threaded onto the inner wall of the liquid outlet hole.

[0012] Furthermore, the interior of the insulated box is filled with coolant, with a coolant filling rate of 60-90%.

[0013] Furthermore, the interior of the insulated box is equipped with a cooling element, which is electrically connected to the controller.

[0014] Furthermore, the interior of the rectangular frame is hollow, and the frame itself is made of thermally conductive material.

[0015] Furthermore, the interior of the rectangular frame is equipped with a heat insulation layer made of fiberglass.

[0016] Compared to existing technologies, the advantages of this application are:

[0017] (1) By setting up a liquid storage bladder and a temperature control box, the liquid storage bladder is squeezed when the motor body vibrates, and the liquid inside is sent to the elastic bladder inside the temperature control box. On the one hand, the liquid pressure generated during the process achieves a comprehensive buffering effect on the motor body, effectively solving the problem of damage to the motor body caused by violent vibration and affecting its working stability. On the other hand, the heat generated during the operation of the motor is absorbed and stored by the heat conduction plate and the heat storage liquid. When the heat conduction liquid comes into contact with the heat storage liquid, it can heat it, so that when it returns to the outer surface of the motor body, it heats and keeps the motor body warm, reducing the heat loss from the outside of the motor body, reducing its failure rate, and ensuring its working stability. Finally, by using coolant to replace the heat storage liquid and turning on the cooling plate, the motor body can be effectively cooled, thereby increasing the versatility of the device and making it usable in both winter and summer.

[0018] (2) By setting elastic silicone in the reservoir bladders on the inner wall of the rectangular frame, the reset effect of the rectangular frame can be increased. When the motor body vibrates, it will squeeze the reservoir bladder in one direction. The liquid in the reservoir bladder enters the interior of the elastic bladder through the connecting pipe and forces it to expand. The liquid pressure provides resistance to the motor body during the movement process, thereby effectively reducing the impact. Similarly, the motor body is effectively buffered in all directions to ensure that its vibration amplitude is reduced and its working stability is ensured.

[0019] (3) By setting up heat storage oil, it is convenient to absorb the heat emitted by the motor body itself through the heat conduction plate. When the motor body starts to rotate, the turntable can be fixed outside the drive shaft by turning on the electromagnet, thereby driving multiple stirring rods to rotate. This ensures that heat is exchanged inside the heat storage oil and also accelerates the transfer of heat to the heat conduction oil inside the elastic bladder. When the heat conduction oil returns to the liquid storage bladder, it can heat and keep the motor body warm, reduce the heat loss outside the motor body, reduce its failure rate, and ensure its working stability.

[0020] (4) In winter, the insulation layer can be stuffed into the rectangular frame to further insulate the motor body and ensure that the motor body can work normally.

[0021] (5) When used in summer, the above structure can be disassembled, the electromagnet can be turned off, the turntable can be disassembled, and then the load on the drive shaft can be reduced, reducing the energy consumption of the motor body. Since there is heat-conducting liquid inside the reservoir, the heat-conducting liquid inside the reservoir can directly diffuse the heat emitted by the motor body to the outside through the rectangular frame of the heat-conducting material. The heat-conducting liquid entering the elastic bladder can also exchange heat with the coolant, and can also help the motor body to remove its surface heat, thereby achieving the purpose of cooling.

[0022] (6) When the cooling is not ideal, the turntable can be reinstalled and connected to multiple right-angle rods. At the same time, the cooling plate is turned on. When the motor body is restarted, the drive shaft drives the stirring rod to rotate through multiple right-angle rods, driven plate and driven shaft, thereby exchanging heat with the internal coolant, which helps to cool the heat transfer fluid that enters the elastic bladder, thereby accelerating the cooling rate of the motor body.

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] Example 1:

[0037] This application discloses a high-power servo motor with high stability. Please refer to [link / reference]. Figure 1-2 The device includes a motor body 1, a drive shaft 2 fixedly connected to the output end of the motor body 1, a rectangular frame 5 slidably connected to the outer end of the motor body 1, a plurality of evenly distributed liquid storage bladders 9 fixedly connected to the inner wall of the rectangular frame 5, a plurality of right-angle plates 11 fixedly connected to the outer end of the rectangular frame 5, a temperature control box 8 fixedly connected to the rectangular frame 5 through the right-angle plates 11, an electromagnet sleeved on the outer wall of the drive shaft 2, a turntable 3 fixedly connected to the outer wall of the electromagnet, a plurality of evenly distributed right-angle rods 7 detachably connected to the side end of the turntable 3, a driven plate 4 provided on the outer side of the temperature control box 8, one end of each of the plurality of right-angle rods 7 fixedly connected to the outer end of the driven plate 4, and a driven shaft 6 fixedly connected to one end of the driven plate 4.

[0038] Please see Figure 3-4 The temperature control box 8 includes an insulated box 81 made of heat-insulating material. The insulated box 81 has multiple elastic bladders 83 inside. One end of the driven shaft 6 extends through the insulated box 81. Multiple stirring rods 82 are fixedly connected to the outer end of the driven shaft 6. A heat-conducting plate 86 is embedded in the outer end of the insulated box 81 near the motor body 1. One side of the heat-conducting plate 86 extends through the interior of the insulated box 81, and the other side of the heat-conducting plate 86 contacts and connects to the outer end of the motor body 1. Multiple leak-proof holes 87 with sealing rings are opened at the outer end of the insulated box 81. A connecting pipe 10 is fixedly connected to the inner wall of the leak-proof hole 87. Multiple liquid storage bladders 9 are fixedly connected to and communicate with the elastic bladders 83 through the connecting pipe 10.

[0039] Please refer to Figure 10The rectangular frame 5 is fixed to a specific location by bolts. Multiple movable shafts 14 are fixedly connected to one side of the rectangular frame 5. A movable box 15 is provided on the outside of the movable shaft 14. A limit groove 16 is opened on one side of the movable box 15. A sliding groove for the movable box 15 to move is opened on the motor body 1. Therefore, the motor body 1 can move freely in a small range in the horizontal and vertical directions on the rectangular frame 5 through the movable box 15.

[0040] The liquid reservoir 9 is made of rubber and is in contact with the outer end of the motor body 1. The connecting pipe 10 is made of inelastic soft material, and the inside of the liquid reservoir 9 is filled with heat-conducting liquid.

[0041] Turntable 3 is made of thin iron material. One end of right-angle rod 7 near turntable 3 is fixedly connected to an iron plate, and one end of electromagnet is connected to a controller for electrical signal.

[0042] A waterproof bearing is fixedly connected between the outside of the driven shaft 6 and the inner wall of the insulation box 81. The insulation box 81 can be cylindrical or cubic.

[0043] During operation, the motor body 1 will experience severe vibrations, affecting its stability. Therefore, it is necessary to perform buffering and shock absorption treatment.

[0044] During operation: Ideally, elastic silicone can be placed in the reservoir 9 on the inner wall of the rectangular frame 5 to increase its reset effect. When the motor body 1 vibrates in one direction, it will squeeze the reservoir 9 in that direction. The liquid in the reservoir 9 enters the interior of the elastic bladder 83 through the connecting pipe 10. The liquid pressure provides a counterforce to the motor body 1, thereby effectively reducing its impact. Similarly, the motor body 1 is effectively buffered in all directions to ensure that its vibration amplitude is reduced and its working stability is ensured.

[0045] The interior of the insulated box 81 is filled with thermal storage oil 85, with a filling rate of 60-90%, and the optimal filling rate is 70%.

[0046] In cold winters, the oil or lubricating oil inside the motor body 1 will solidify due to the low temperature, affecting the stability of the motor body 1. Therefore, heat storage oil 85 can be added to absorb and store heat.

[0047] The heat emitted by the motor body 1 is transferred to the heat storage oil 85 through the heat conduction plate 86. When the motor body 1 starts to rotate, the electromagnet can be turned on to fix the turntable 3 to the outside of the drive shaft 2. The turntable 3 drives multiple right-angle rods 7 to rotate, which indirectly drives the driven plate 4 to rotate. Finally, by driving multiple stirring rods 82 to rotate, heat exchange is ensured inside the heat storage oil 85. At the same time, heat is also conveniently transferred to the heat conduction oil inside the elastic bladder 83. When the heat conduction oil returns to the liquid storage bladder 9, it can heat and keep the motor body 1 warm, ensuring that the low temperature environment outside will not absorb the heat from the outside of the motor body 1.

[0048] The right-angle rod 7, driven plate 4 and driven shaft 6 are all made of lightweight materials. The bottom of the insulated box 81 is provided with a liquid outlet hole, and the inner wall of the liquid outlet hole is threaded with a sealing valve 84.

[0049] Please see Figure 9 The rectangular frame 5 has a hollow structure inside and is made of thermally conductive material. The rectangular frame 5 has a heat insulation layer 13 inside and is made of fiberglass.

[0050] In winter, the heat insulation layer 13 can be inserted into the rectangular frame 5 to achieve the purpose of heat insulation for the motor body 1, effectively preventing excessive heat loss from the motor body 1, which could lead to unstable operation and easy failure.

[0051] Example 2:

[0052] Please see Figure 7-8 The difference between Example 2 and Example 1 is that the interior of the insulated box 81 is filled with coolant, and the coolant filling rate is 60-90%.

[0053] The following technical features have also been added: the interior of the insulated box 81 is equipped with a cooling chip 12, which is electrically connected to the controller.

[0054] In this embodiment, the heat insulation layer 13 inside the rectangular frame 5 needs to be removed.

[0055] When used in summer, the above structure can be disassembled, the electromagnet can be turned off, and the turntable 3 can be disassembled. This will reduce the load on the drive shaft 2 and reduce the energy consumption of the motor body 2. Since there is a heat-conducting liquid inside the liquid reservoir 9, the heat-conducting liquid inside the liquid reservoir 9 can diffuse heat to the outside through the rectangular frame 5 of the heat-conducting material. The heat-conducting liquid entering the elastic bladder 83 exchanges heat with the coolant, which can also help the motor body 1 remove surface heat. When it is found that the heat dissipation is insufficient, the turntable 3 can be reinstalled and connected to multiple right-angle rods 7. At the same time, the cooling plate 12 is turned on. When the motor body 1 is restarted, the drive shaft 2 drives the stirring rod 82 to rotate through multiple right-angle rods 7, driven plate 4 and driven shaft 6, thereby exchanging heat with the internal coolant, which in turn helps to cool the heat-conducting liquid entering the elastic bladder 83, thereby accelerating the cooling rate of the motor body 1.

[0056] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
