Description

Technical Field

[0001] This invention relates to the field of servo motor heat dissipation, and more specifically, to a high-power servo motor with high heat dissipation. Background Technology

[0002] A servo motor is a type of motor in a servo system that controls the operation of mechanical components; it is an auxiliary motor with indirect speed control. Servo motors can control speed and position with very high accuracy.

[0003] Servo motors tend to generate a lot of heat when operating at high power for extended periods. The heat generated cannot be quickly cooled down by relying solely on the motor casing for heat dissipation. Prolonged high-temperature operation of servo motors can easily damage the motor. Furthermore, servo motors are prone to vibration when operating at high power, which reduces the transmission efficiency. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the present invention aims to provide a high-heat-dissipation, high-power servo motor that can cool the motor casing by using ethanol liquid in the storage chamber, and the reflux of ethanol liquid makes the cooling less likely to be interrupted, as well as the buffer structure to buffer vibration and improve the transmission effect.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A high-power servo motor with high heat dissipation includes a motor body, a heat dissipation device sleeved on the outside of the motor body, and a housing. Two liquid storage chambers are formed in the middle of the housing. Storage boxes are fixedly connected to both ends of the housing. A processor is fixedly connected to the middle of each storage box. Four tension springs are fixedly connected to the inside of each storage box. Two partition structures are fixedly connected to the ends of the tension springs away from the inside of the storage box. A buffer structure is fixedly connected to the lower end of the storage box. A condenser tube is fixedly connected to the upper end of the storage box, and a cooling box is fixedly connected to the outer end of the condenser tube. The motor housing is cooled by ethanol liquid in the storage chambers, and the reflux of the ethanol liquid makes cooling less likely to be interrupted. The buffer structure also provides vibration damping, improving the transmission effect.

[0009] Furthermore, the separation structure includes a baffle with a rectangular hole in the middle. A storage slot is formed at the outer end of the rectangular hole on the inner side of the baffle. An electric telescopic rod is fixedly installed in the middle of the storage slot. A sensor is fixedly connected to the middle of the electric telescopic rod, and a cover is fixedly connected to the front end of the electric telescopic rod, so that high-temperature liquid ethanol and room-temperature ethanol can be separated.

[0010] Furthermore, the buffer structure includes a base, a cylindrical sleeve fixedly connected to the upper end of the base, a support spring fixedly connected to the middle of the cylindrical sleeve, a support block fixedly connected to the upper end of the support spring, and a baffle fixedly connected to the lower end of the support block. The baffle has multiple round holes at equal angles in the middle, which reduces the vibration effect of the motor body.

[0011] Furthermore, the liquid storage chamber and the material storage box are internally connected, and the liquid storage chamber and the material storage box contain ethanol liquid, so that the ethanol liquid can carry away the heat released by the motor body.

[0012] Furthermore, the cover is matched with the rectangular hole, and the sensor is electrically connected to the processor, so that the cover can cover the rectangular hole, and the processor can send an electrical signal to the sensor.

[0013] Furthermore, the two baffles are fixedly connected, and the cross-sections of the two baffles match the inner side of the storage box, so that the two baffles can separate the interior of the storage box.

[0014] Furthermore, the cylindrical sleeve contains a viscous liquid with a viscosity between 5000 and 10000 mPa·s, which reduces the vibration amplitude of the motor body through its viscosity.

[0015] Furthermore, the condenser tube is multi-bent in shape, and the end of the condenser tube away from the storage box is fixedly connected to the shell, so that the condenser tube can have sufficient length to achieve the condensation effect, and the condenser tube allows the ethanol liquid to flow back.

[0016] Furthermore, the condenser tube is connected to the liquid storage chamber, and the cooling box contains coolant, which allows the cooling box to accelerate the condensation of ethanol vapor inside the condenser tube.

[0017] Furthermore, the internal material of the condenser is a copper alloy, and the internal material of the baffle is a heat-insulating material, which allows the condenser to accelerate heat conduction, and the baffle can reduce the heat conduction of the ethanol liquid on both sides.

[0025] (6) The two baffles are fixedly connected, and the cross-sections of the two baffles match the inside of the storage box, so that the two baffles can separate the inside of the storage box.

[0026] (7) The cylindrical sleeve contains a viscous liquid with a viscosity between 5000-1000 mPa·s, which reduces the vibration amplitude of the motor body by the viscosity of the viscous liquid.

[0045] Please see Figure 1-10 A high-power servo motor with high heat dissipation includes a motor body 1. A heat dissipation device is sleeved on the outside of the motor body 1. The heat dissipation device includes a housing 2. Two liquid storage chambers 3 are opened in the middle of the housing 2. Storage boxes 4 are fixedly connected to both ends of the housing 2. A processor 5 is fixedly connected to the middle of the storage box 4. Four tension springs 6 are fixedly connected to the inside of the storage box 4. Two partition structures 7 are fixedly connected to the end of the tension springs 6 away from the inside of the storage box 4. A buffer structure 8 is fixedly connected to the lower end of the storage box 4. A condenser pipe 9 is fixedly connected to the upper end of the storage box 4. A cooling box 10 is fixedly connected to the outer end of the condenser pipe 9.

[0046] Please see Figure 3-7 The separation structure 7 includes a baffle 701 with a rectangular hole 702 in the middle. A storage slot 703 is located inside the baffle 701 at the outer end of the rectangular hole 702. An electric telescopic rod 704 is fixedly installed in the middle of the storage slot 703. A sensor 705 is fixedly connected to the middle of the electric telescopic rod 704. A cover 706 is fixedly connected to the front end of the electric telescopic rod 704, allowing the high-temperature liquid ethanol and room-temperature ethanol to be separated. The buffer structure 8 includes a base 801 with a cylindrical sleeve 802 fixedly connected to its upper end. A support spring 803 is fixedly connected to the middle of the cylindrical sleeve 802. A support block 804 is fixedly connected to the upper end of the support spring 803. A baffle 805 is fixedly connected to the lower outer end of the support block 804. Multiple circular holes 806 are equally spaced in the middle of the baffle 805, reducing the vibration of the motor body 1.

[0047] Please see Figure 5-8 The liquid storage chamber 3 and the material storage box 4 are internally connected, and both contain ethanol liquid, which allows the ethanol liquid to carry away the heat released by the motor body 1. The cover 706 matches the rectangular hole 702, and the sensor 705 is electrically connected to the processor 5, so that the cover 706 can cover the rectangular hole 702, and the processor 5 can send an electrical signal to the sensor 705.

[0048] Please see Figure 4-9Two baffles 701 are fixedly connected, and their cross-sections match the inner side of the storage box 4, allowing them to separate the interior of the storage box 704. The cylindrical sleeve 802 contains a viscous liquid with a viscosity between 5000-1000 mPa·s, which reduces the vibration amplitude of the motor body 1 due to its viscosity. The condenser tube 9 has a multi-stage curved shape, and its end away from the storage box 4 is fixedly connected to the housing 2, ensuring sufficient length for condensation and allowing the ethanol liquid to flow back.

[0049] Please see Figure 3-5 The condenser tube 9 is connected to the liquid storage chamber 3, and the cooling box 10 contains coolant, which allows the cooling box 10 to accelerate the condensation of ethanol vapor inside the condenser tube 9. The internal material of the condenser tube 9 is copper alloy, and the internal material of the baffle 701 is heat-insulating material, which allows the condenser tube 9 to accelerate heat conduction, and the baffle 701 to reduce heat conduction of ethanol liquid on both sides.

[0050] When the motor body 1 operates at high power for an extended period, the outer casing of the motor body 1 heats up. This heat is conducted through the casing 2 into the liquid storage chamber 3. The ethanol liquid in the liquid storage chamber 3 evaporates and rises into the condenser pipe 9. The evaporation of ethanol carries away a large amount of heat. The ethanol vapor passes through the condenser pipe 9 and is liquefied again by the cooling effect of the cooling box 10. The liquid ethanol then enters the storage box 4 through the end of the condenser pipe 9 closest to the storage box 4. At this point, the temperature of the liquid ethanol is still above 60 degrees Celsius. The liquid ethanol located on the side of the baffle 701 away from the casing 2 is insulated by the baffle 701. Simultaneously, the liquid ethanol on the side of the baffle 701 away from the casing 2 pushes the baffle 701 towards the casing 2. When the separating structure 7 moves a certain distance, the liquid ethanol located on the side of the baffle 701 away from the casing 2... The temperature of the liquid ethanol on the side of the baffle 701 away from the housing 2 has dropped to room temperature, and the sensor 705 is in contact with the processor 5. The processor 5 sends an electrical signal to the sensor 705 to control the electric telescopic rod 704 to retract, so that the cover 706 no longer blocks the rectangular hole 702. The liquid ethanol on the side of the baffle 701 away from the housing 2 flows into the side of the baffle 701 closer to the housing 2 through the rectangular hole 702. At the same time, the tension spring 6 pulls the partition structure 7 to move away from the housing 2. When the partition structure 7 moves to the initial position, the electric telescopic rod 704 controls the cover 706 to cover the rectangular hole 702 again, and the liquid ethanol on the side of the baffle 701 closer to the housing 2 continues to cool the motor body 1.

[0051] When the motor body 1 vibrates, the support block 804 vibrates up and down, and the viscous liquid stored inside the cylindrical sleeve 802 continuously flows up and down through the round hole 806. Due to the viscosity of the viscous liquid, the vibration amplitude of the baffle 805 is limited, reducing the vibration problem of the motor body 1. The ethanol liquid in the liquid storage chamber 3 cools the motor casing, and the backflow of the ethanol liquid makes the cooling less likely to be interrupted. In addition, the buffer structure 8 buffers the vibration, improving the transmission effect.

[0052] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
