Description

Technical Field

[0001] This utility model relates to the field of servo motor housing technology, and more specifically, to a dual-cooling-cavity housing for an ultra-high-speed servo motor specifically for glass polishing. Background Technology

[0002] In the glass polishing process, the ultra-high-speed servo motor, as the core power component, needs to maintain high speed for a long time to meet the high precision and high efficiency requirements of glass polishing. However, ultra-high-speed operation will generate a lot of heat inside the motor, mainly from the electromagnetic losses of the motor stator and rotor, bearing friction, and the motion friction of mechanical parts. Excessive temperature will seriously affect the performance of the motor, such as causing the insulation performance of the motor windings to degrade, increasing the risk of short circuits; causing the magnetic materials of the motor rotor and stator to degrade, reducing the output power and torque stability of the motor; and accelerating the wear of internal parts of the motor, significantly shortening the service life of the motor.

[0003] Existing motor cooling methods rely solely on fans or simple single-cooling-cavity housings, which are insufficient to quickly dissipate the heat generated by the motor and cannot meet the cooling requirements of ultra-high-speed servo motors for glass polishing. Therefore, a dual-cooling-cavity housing for ultra-high-speed servo motors for glass polishing is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a dual-cooling-chamber housing for a special ultra-high-speed servo motor for glass polishing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-cooling-cavity housing for a high-speed servo motor for glass polishing, comprising a housing, an end cap at one end of the housing, and a protective cap at the other end of the housing. The end cap and the protective cap are used to seal both ends of the housing, protecting the core components such as the rotor and stator inside the motor, preventing dust and impurities from entering the motor, and providing a convenient interface for the installation and maintenance of the motor. A first cooling cavity is provided in the middle of the housing, which serves as the main cooling area and is used to contain coolant to remove the heat generated by the motor operation. Multiple heat-conducting strips are fixedly connected to the inner cavity of the first cooling cavity. The heat-conducting strips can quickly conduct the heat generated by the shaft, rotor, and other components to the coolant in the first cooling cavity, improving heat transfer efficiency and accelerating heat dissipation. A heat exchange cavity is provided in the middle of one end wall of the protective cap of the housing.

[0006] A heat-conducting ring is fixedly connected to the middle of the heat exchange chamber, which serves to exchange heat with the coolant in the first cooling chamber after it has absorbed heat, thereby reducing the coolant temperature for recycling. A connecting ring and multiple heat dissipation fins are fixedly connected to one end of the shell near the protective cover. The heat dissipation fins accelerate airflow, thereby improving heat dissipation efficiency. When air flows through the heat dissipation fins, it can carry away the heat from the surface of the shell, assisting in cooling the motor. The surface of the connecting ring has through holes. A second cooling chamber is formed in the middle of the end cover. The second cooling chamber, together with the first cooling chamber and the heat exchange chamber, constitutes a dual cooling circulation system. A liquid pump is fixedly connected to one side of the bottom of the shell. Fixed columns and dustproof mesh rings located in the middle of the fixed columns are symmetrically fixedly connected around one side of the protective cover. Driven by the liquid pump, the coolant circulates between the second cooling chamber, the first cooling chamber, and the heat exchange chamber. After absorbing the heat generated by the motor in the first cooling chamber, the coolant enters the heat exchange chamber through the connecting pipe for heat exchange. After the temperature drops, it flows into the second cooling chamber and is pumped back to the first cooling chamber, realizing the recycling of the coolant and continuously dissipating heat for the motor. The dustproof mesh ring corresponds to the through hole and can effectively prevent dust and impurities from entering and adhering to the heat conduction ring, thus affecting the heat dissipation efficiency.

[0007] Preferably, a rotating shaft is provided in the middle of the housing, one end of the rotating shaft penetrates the wall of the housing and is fixedly connected to multiple fan blades, and the other end of the rotating shaft penetrates the end cover and extends to the outside.

[0008] Preferably, a rotor is fixedly sleeved in the middle of the rotating shaft, and a stator is provided on the outside of the rotor. The stator is fixed in the middle of the housing. When the motor is running, the rotating shaft drives the fan blades to rotate. The rotation of the fan blades generates airflow, which accelerates the airflow speed outside the housing. In conjunction with the heat dissipation fins, the heat dissipation efficiency is further improved and the air cooling effect is enhanced.

[0009] Preferably, the input end of the liquid pump is connected to the bottom of the inner cavity of the second cooling chamber, and the output end of the liquid pump is connected to the bottom of the inner cavity of the first cooling chamber.

[0010] Preferably, the top of the inner cavity of the first cooling chamber is connected to the bottom of the inner cavity of the heat exchange chamber through a connecting pipe, and the top of the inner cavity of the heat exchange chamber is connected to the top of the inner cavity of the second cooling chamber through a connecting pipe. Driven by a liquid pump, the coolant circulates between the second cooling chamber, the first cooling chamber, and the heat exchange chamber. After absorbing the heat generated by the motor in the first cooling chamber, the coolant enters the heat exchange chamber through the connecting pipe for heat exchange. After the temperature drops, it flows into the second cooling chamber and is then pumped back to the first cooling chamber by the liquid pump, thus realizing the recycling of the coolant.

[0011] Preferably, the heat-conducting strip is fixed on the side wall of the first cooling chamber near the rotating shaft, and the heat-conducting ring is fixed on the side wall of the heat exchange chamber near the protective cover.

[0012] Preferably, a rivet is inserted in the middle of the fixed column, the rivet penetrates the wall of the connecting ring, the dustproof mesh ring corresponds to the through hole, the cross-sectional shape of the heat dissipation fin ring is set to "V" shape, the surface of the heat dissipation fin ring is provided with through holes, and the periphery of the end cover is fixedly connected to one side wall of the housing by rivets, which ensures a stable connection between the various components of the housing and ensures the stability and reliability of the dual cooling chamber housing during motor operation.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model firstly uses a liquid pump to drive the coolant to circulate between the second cooling chamber, the first cooling chamber, and the heat exchange chamber. The dual cooling chamber structure, combined with components such as heat-conducting strips, heat-conducting rings, and heat dissipation fins, forms a comprehensive and multi-layered heat dissipation system. The first cooling chamber directly cools the core components of the motor, the heat-conducting strips quickly conduct heat, the heat exchange chamber realizes the heat exchange of the coolant, and the heat dissipation fins and fan blades enhance the air cooling effect. The synergistic effect of multiple heat dissipation methods greatly improves the heat dissipation efficiency, can quickly and effectively reduce the operating temperature of the motor, and ensure the stability and reliability of the motor under ultra-high speed operation.

[0015] 2. This utility model also effectively prevents dust and impurities from entering the middle of the protective cover through the dustproof mesh ring, thereby adhering to the surface of the heat dissipation fin ring and affecting the heat dissipation effect of the heat dissipation fin ring. At the same time, the coolant circulates in the dual cooling circulation system, realizing the reuse of coolant, reducing coolant consumption, lowering operating costs, and also reducing the pollution caused by coolant discharge to the environment, which has good environmental benefits. The shell, end cover, and protective cover are connected by rivets and bolts, ensuring a stable connection between the various parts of the shell, ensuring the stability and reliability of the dual cooling chamber shell during motor operation.

[0016] In summary, through the interaction of the above-mentioned multiple functions, and by setting up a dual cooling chamber structure combined with components such as heat-conducting strips, heat-conducting rings, and heat dissipation fins, a comprehensive and multi-layered heat dissipation system is formed. The heat exchange chamber realizes the heat exchange of the coolant, while the heat dissipation fins and fan blades enhance the air cooling effect. The synergistic effect of multiple heat dissipation methods greatly improves the heat dissipation efficiency, which can quickly and effectively reduce the motor operating temperature and ensure the stability and reliability of the motor under ultra-high speed operation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1-5 The glass polishing-specific ultra-high-speed servo motor dual-cooling-cavity housing shown includes a housing 1. One end of the housing 1 is provided with an end cap 9, and the other end of the housing 1 is provided with a protective cap 12. The end cap 9 and the protective cap 12 are used to seal both ends of the housing 1, protecting the core components such as the rotor 16 and stator 18 inside the motor, preventing dust and impurities from entering the motor, and providing a convenient interface for the installation and maintenance of the motor. A first cooling cavity 2 is opened in the middle of the housing 1. The first cooling cavity 2 serves as the main cooling area, used to contain coolant and remove the heat generated by the motor operation. Multiple heat-conducting strips 3 are fixedly connected to the inner cavity of the first cooling cavity 2. The heat-conducting strips 3 can quickly conduct the heat generated by the shaft 15, rotor 16 and other components to the coolant in the first cooling cavity 2, improving the heat transfer efficiency and accelerating the heat dissipation speed. A heat exchange cavity 4 is opened in the middle of one end wall of the protective cap 12 of the housing 1.

[0025] A heat-conducting ring 5 is fixedly connected to the middle of the heat exchange chamber 4. The heat exchange chamber 4 plays the role of heat exchange, exchanging heat with the coolant after it has absorbed heat in the first cooling chamber 2, thereby reducing the temperature of the coolant for recycling. A connecting ring 6 and multiple heat dissipation fins 8 are fixedly connected to one end of the shell 1 near the protective cover 12. The heat dissipation fins 8 accelerate the airflow speed, thereby improving the heat dissipation efficiency. When the air flows through the heat dissipation fins 8, it can carry away the heat on the surface of the shell 1, assisting in cooling the motor. A through hole 7 is opened on the surface of the connecting ring 6. A second cooling chamber 10 is opened in the middle of the end cover 9. The second cooling chamber 10, together with the first cooling chamber 2 and the heat exchange chamber 4, constitutes a dual cooling circulation system. A liquid pump 11 is fixedly connected to one side of the bottom of the shell 1. A fixing post 13 and a dustproof mesh ring 14 located in the middle of the fixing post 13 are symmetrically fixedly connected around one side of the protective cover 12. Driven by the liquid pump 11, the coolant circulates between the second cooling chamber 10, the first cooling chamber 2 and the heat exchange chamber 4. After absorbing the heat generated by the motor in the first cooling chamber 2, the coolant enters the heat exchange chamber 4 through the connecting pipe for heat exchange. After the temperature drops, it flows into the second cooling chamber 10 and is pumped back to the first cooling chamber 2 by the liquid pump 11, realizing the recycling of the coolant and continuously dissipating heat for the motor. The dustproof mesh ring 14 corresponds to the through hole 7 and can effectively prevent dust and impurities from entering and adhering to the heat conduction ring 5, thus affecting the heat dissipation efficiency.

[0026] As attached Figure 1 , 2 As shown, a rotating shaft 15 is provided in the middle of the housing 1. One end of the rotating shaft 15 passes through the wall of the housing 1 and is fixedly connected to multiple fan blades 17. The other end of the rotating shaft 15 passes through the end cover 9 and extends to the outside. A rotor 16 is fixedly sleeved in the middle of the rotating shaft 15. A stator 18 is provided outside the rotor 16. The stator 18 is fixed in the middle of the housing 1. When the motor is running, the rotating shaft 15 drives the fan blades 17 to rotate. The rotation of the fan blades 17 generates airflow, which accelerates the airflow speed outside the housing 1. In conjunction with the heat dissipation fin ring 8, the heat dissipation efficiency is further improved and the air cooling effect is enhanced.

[0027] As attached Figure 1-5As shown, the input end of the liquid pump 11 is connected to the bottom of the inner cavity of the second cooling chamber 10, and the output end of the liquid pump 11 is connected to the bottom of the inner cavity of the first cooling chamber 2. The top of the inner cavity of the first cooling chamber 2 is connected to the bottom of the inner cavity of the heat exchange chamber 4 through a connecting pipe, and the top of the inner cavity of the heat exchange chamber 4 is connected to the top of the inner cavity of the second cooling chamber 10 through a connecting pipe. Driven by the liquid pump 11, the coolant circulates between the second cooling chamber 10, the first cooling chamber 2, and the heat exchange chamber 4. After absorbing the heat generated by the motor in the first cooling chamber 2, the coolant enters the heat exchange chamber 4 through the connecting pipe for heat exchange. After the temperature drops, it flows into the second cooling chamber 10 and is then pumped back to the first cooling chamber 2 by the liquid pump 11, realizing the recycling of the coolant. The heat-conducting strip 3 is fixed on the side wall of the inner cavity of the first cooling chamber 2 near the rotating shaft 15. The heat-conducting ring 5 is fixed on the side wall of the inner cavity of the heat exchange chamber 4 near the protective cover 12. A rivet is inserted in the middle of the fixing column 13, and the rivet penetrates the wall of the connecting ring 6. The dustproof mesh ring 14 corresponds to the through hole 7. The cross-sectional shape of the heat dissipation fin ring 8 is set as "V" shape, and the surface of the heat dissipation fin ring 8 is provided with through holes. The four sides of the end cover 9 are fixedly connected to one side wall of the housing 1 by rivets, ensuring a stable connection between the various components of the housing and ensuring the stability and reliability of the dual cooling chamber housing during motor operation.

[0028] The working principle of this utility model is as follows: Before use, coolant is injected into the first cooling chamber 2 through the through hole at the sealing block 19. When the motor starts and generates heat, the heat inside the housing 1 will be transferred to the coolant through the housing 1 and the heat conduction strip 3.

[0029] During cooling operation, the coolant can be circulated between the second cooling chamber 10, the first cooling chamber 2, and the heat exchange chamber 4 by starting the liquid pump 11. After absorbing the heat generated by the motor in the first cooling chamber 2, the coolant enters the heat exchange chamber 4 through the connecting pipe to exchange heat with the heat-conducting ring 5. The cooled coolant then flows back into the second cooling chamber 10 and is pumped back into the first cooling chamber 2 by the liquid pump 11 for cooling, realizing the recycling of the coolant, continuously dissipating heat from the motor, and improving the heat dissipation effect.

[0030] While the coolant exchanges heat inside the heat exchange chamber 4, the heat conduction ring 5 transfers heat to the heat dissipation fin ring 8. The fan blade 17 rotates with the shaft 15 to cool the heat dissipation fin ring 8, thus cooling the coolant. External gas will enter the protective cover 12 through the dustproof mesh ring 14 and carry away the heat on the surface of the heat dissipation fin ring 8, and then be discharged through the through hole in the middle of the protective cover 12.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
