Description
Technical Field

It is specifically suitable for industrial scenarios that require long-term continuous operation and high heat dissipation requirements, such as heavy machinery transmission systems, chemical production line drive units, and power devices for new energy equipment.
[0003] Existing technical solutions often rely on passive cooling or simple air cooling, which has low heat dissipation efficiency. When running under continuous high load, the heat generated by gear meshing friction and bearing rotation loss cannot be dissipated in time, and the internal temperature can easily rise to above 80°C. This can lead to a decrease in lubricating oil viscosity, failure of lubrication performance, and in turn cause failures such as tooth surface scuffing and bearing seizure.
[0004] To address the above problems, this utility model provides a speed reducer that prevents high-temperature overload. Utility Model Content

[0009] Furthermore, a front-end temperature sensor is fixedly connected to the top of the water-cooled mounting shell, and a connecting plate is fixedly connected to one side of the water-cooled mounting shell. A limiting component is threadedly connected to one side of the connecting plate, and the connecting plate is threadedly connected to one side of the water-cooled mounting shell through the limiting component.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] In this invention, the high-efficiency condenser, water-cooled circulation pipes, and cooling fans are used to quickly remove heat from the reducer body through the spiral pipes and the high-efficiency condenser.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a speed reducer to prevent high temperature overload, including a bottom fixing plate 1, a speed reducer water cooling heat dissipation mechanism 2 and a motor air cooling heat dissipation mechanism 3. There are two bottom fixing plates 1, and the bottom of the speed reducer water cooling heat dissipation mechanism 2 and the motor air cooling heat dissipation mechanism 3 are fixedly connected to the two bottom fixing plates 1. Ground connecting parts 4 are threaded to both sides of the bottom fixing plate 1.
[0026] The following section will explain the specific setup and function of the reducer water-cooled heat dissipation mechanism 2 and the motor air-cooled heat dissipation mechanism 3.
[0027] In this embodiment: the reducer water cooling heat dissipation mechanism 2 includes a high-efficiency condenser 21 and a water cooling circulation pipe 22, and the motor air cooling heat dissipation mechanism 3 includes a permeable filter plate 31 and a cooling fan 32.
[0028] The reducer water cooling heat dissipation mechanism 2 includes a water cooling mounting shell 23 fixedly connected to the top of the bottom fixing plate 1. The inner wall of the water cooling mounting shell 23 is provided with a spiral placement groove 24. The water cooling circulation pipe 22 is fixedly connected to the inside of the spiral placement groove 24. The two ends of the water cooling circulation pipe 22 are fixedly connected to the two ends of the high-efficiency condenser 21. The high-efficiency condenser 21 is fixedly connected to the outer surface of the water cooling mounting shell 23. The outer surface of the water cooling circulation pipe 22 is fixedly connected to the circulating water pump 25. The outer surface of the circulating water pump 25 is fixedly connected to the outer surface of the water cooling mounting shell 23.
[0029] The effects achieved by the above components are as follows: the spiral placement grooves 24 on the inner wall of the water-cooled mounting shell 23 allow the water-cooled circulation pipe 22 to fit tightly against the inner wall of the shell, and the circulating water in the pipe can quickly absorb the heat of the reducer body 310 transferred by the mounting shell, avoiding pipe deformation due to high temperature and ensuring long-term stable heat exchange. The high-efficiency condenser 21 can quickly absorb the heat of the circulating water, and the circulating water pump 25 provides stable power for the circulating water, ensuring that the heat is delivered to the condenser in a timely manner to form a complete water-cooled cycle. The circulating water pump 25 and the condenser are both fixed to the outer surface of the water-cooled mounting shell 23, avoiding the increase of water flow resistance caused by excessive pipe length, and reducing the impact of external vibration on the heat dissipation system.
[0030] Specifically, a front-end temperature sensor 26 is fixedly connected to the top of the water-cooled mounting shell 23, and a connecting plate 27 is fixedly connected to one side of the water-cooled mounting shell 23. A limiting member 28 is threadedly connected to one side of the connecting plate 27, and the connecting plate 27 is threadedly connected to one side of the water-cooled mounting shell 23 through the limiting member 28.
[0031] The effects achieved by the above components are as follows: the front-end temperature sensor 26 can directly monitor the surface temperature of the reducer body 310, providing accurate data support for subsequent heat dissipation control; the connecting plate 27 and the water-cooled mounting shell 23 are detachably connected, which not only ensures the connection strength, but also facilitates subsequent disassembly and maintenance; the connecting plate 27 and the water-cooled mounting shell 23 are subjected to uniform force, avoiding installation deviation caused by unilateral force, ensuring the coaxiality of the reducer body 310 and the motor air-cooled heat dissipation mechanism 3, and reducing vibration and noise during power transmission.
[0032] Specifically, the motor air-cooling heat dissipation mechanism 3 includes a motor protective shell 33 fixedly connected to the other side of the connecting plate 27, and the outer surface of the motor protective shell 33 is fixedly connected to the top of the bottom fixing plate 1.
[0033] The effects achieved by the above components are as follows: the motor protective shell 33 is connected to the reducer water cooling heat dissipation mechanism 2 through the connecting plate 27 to form an integrated structure, reducing the equipment footprint, shortening the power transmission path, and reducing transmission loss. The protective shell and the bottom fixing plate 1 work together to enhance protection and stability. The motor protective shell 33 can effectively block external dust and impurities from entering the motor and prevent short circuits in the motor windings caused by foreign objects.
[0034] Specifically, the outer surface of the motor protective housing 33 is threaded with a wind-cooled mounting housing 34, and the two sides of the wind-cooled mounting housing 34 are threaded with connecting bolts 35. The outer surface of the connecting bolts 35 is threaded with nuts 36. The wind-cooled mounting housing 34 is threaded to the outer surface of the motor protective housing 33 through the connecting bolts 35.
[0035] The above components achieve the following effects: the connecting bolts 35, together with the anti-loosening nuts 36, firmly connect the air-cooled mounting shell 34 and the motor protective shell 33. The anti-loosening nuts 36 can effectively prevent the bolts from loosening due to equipment vibration. At the same time, the detachable design allows the air-cooled mounting shell 34 to be disassembled separately. When the cooling fan 32 or the servo motor 37 fails, it can be repaired without disassembling the motor protective shell 33.
[0036] Specifically, a servo motor 37 is fixedly connected to the inner wall of the air-cooled mounting shell 34, and a cooling fan 32 is fixedly connected to the output end of the servo motor 37.
[0037] The effect achieved by the above components is that the servo motor 37 can dynamically adjust the speed of the cooling fan 32 according to the motor temperature, avoiding the energy waste of traditional fixed-speed fans, and can quickly remove the surface heat of the reducer motor body 39, ensuring stable operation.
[0038] Specifically, the ventilation filter plate 31 is fixedly connected to the outer surface of the air-cooled mounting shell 34, the top of the air-cooled mounting shell 34 is fixedly connected to the end temperature sensor 38, and the motor protective shell 33 is fixedly connected to the motor reducer electric body 39.
[0039] The effects achieved by the above components are as follows: the air-permeable filter plate 31 is fixed to the air inlet end of the air-cooled mounting shell 34, which can filter dust, hair and other impurities in the air, preventing impurities from entering the motor protective shell 33 and adhering to the winding surface of the reducer electric body 39, preventing poor heat dissipation and reduced insulation performance of the winding due to dust accumulation, and reducing the risk of motor burnout; the end temperature sensor 38 is fixed to the top of the air-cooled mounting shell 34, which can monitor the temperature of the reducer electric body 39 in real time, forming a dual-point temperature measurement of the motor and reducer with the front-end temperature sensor 26, avoiding the temperature blind spot caused by single temperature measurement.
[0040] Specifically, the output end of the reducer electric body 39 is rotatably connected to the inside of the connecting plate 27, the output end of the reducer electric body 39 is fixedly connected to the reducer body 310, and the reducer body 310 is fixedly connected to the inside of the water-cooled mounting shell 23.
[0041] The effects achieved by the above components are as follows: the output end of the reducer electric body 39 is connected to the input end of the reducer body 310 through a coupling. The positioning function of the connecting plate 27 ensures the coaxiality of the two, reducing the additional torque and vibration during transmission. The reducer body 310 is fixed in the internal cavity of the water-cooled mounting shell 23, and heat can be quickly transferred to the mounting shell and water-cooling pipes. With the efficient heat dissipation of the water-cooling system, the temperature of the reducer body 310 is kept stable within a reasonable range.
[0042] Working principle: After the reducer electric body 39 is connected to an external power source, it starts. The output end transmits power to the reducer body 310 inside the water-cooled mounting shell 23 through a coupling. The reducer body 310 adjusts the speed and torque through gear meshing to provide power to the external load. During this process, the gear meshing friction of the reducer body 310, the bearing rotation loss, and the heating of the motor windings generate heat, causing the temperature of both to rise.
[0043] The front-end temperature sensor 26 monitors the temperature of the reducer body 310 in real time, and the end-end temperature sensor 38 monitors the temperature of the reducer electric body 39 in real time. The control unit can start the circulating water pump 25. The cooling water in the water-cooled circulation pipe 22 absorbs the heat of the mounting shell, flows through the high-efficiency condenser 21 to dissipate heat, and then flows back to form a water-cooled circulation.
[0044] The control unit can start the servo motor 37 and the cooling fan 32 to run. Cold air is drawn in through the ventilation filter plate 31 and blown directionally onto the motor surface for heat dissipation. The ventilation filter plate 31 can block impurities from entering the motor and prevent dust accumulation from affecting heat dissipation. The water cooling system and the air cooling system start and stop dynamically according to the temperature, which ensures heat dissipation effect and avoids energy waste.
