Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gearboxes, and particularly relates to a gearbox cooling device with a temperature monitoring function. BACKGROUND

[0002] In the modern industrial production system, the gearbox, as the core component of the mechanical transmission system, is widely used in various mechanical equipment, such as wind power equipment, mining machinery, metallurgical equipment, ship power systems, and automobile manufacturing fields. Its main function is to change the speed, convert the torque, and transmit the power through the meshing of gears, to ensure that the equipment can operate stably according to the predetermined working condition.

[0003] With the continuous progress of industrial technology, the operating power and efficiency of mechanical equipment are continuously improved, which puts forward higher requirements for the performance of the gearbox. During the operation of the gearbox, a large amount of heat is generated due to the meshing of gears and the friction of bearings. Excessive temperature not only reduces the viscosity of lubricating oil, reduces the lubrication effect, and accelerates the wear of gears and bearings, but also may cause thermal deformation of the gearbox components, affect the meshing accuracy of gears, and thus reduce the transmission efficiency and reliability of the equipment. In severe cases, it may even cause equipment failure, resulting in production interruption and causing huge economic losses.

[0004] The traditional gearbox cooling method has many limitations. The early natural cooling method relies on natural convection of air for heat dissipation, and the cooling efficiency is extremely low, which is difficult to meet the heat dissipation needs of high-power equipment. Although the simple air cooling method improves the heat dissipation speed to some extent, its cooling effect is still limited for high-temperature and high-load running gearboxes. Some traditional liquid cooling systems lack precise temperature monitoring and control mechanisms, and the flow and cooling strength of the cooling liquid cannot be adjusted in real time according to the actual temperature changes of the gearbox, which may easily cause insufficient cooling or excessive cooling. Insufficient cooling will cause the gearbox temperature to be too high, affecting the performance and service life of the equipment; excessive cooling will cause energy waste and increase the operating cost.

[0028] The cooling assembly 200 comprises a cover plate 201 installed at the end of the box body 113, a liquid storage tank 202 adaptively installed at the side wall of the box body 113, a liquid pump 203 installed at the end of the cover plate 201, a sleeve 204 for installing a sensor installed on the inner wall of the cover plate 201, and a return pipe 205 installed on the side wall of the main shaft 101, the end of the sleeve 204 for installing a sensor extends to the end side wall of the worm gear 103, the liquid inlet of the liquid pump 203 is communicated with the liquid storage tank 202 through a pipeline, the end of the return pipe 205 is communicated with the liquid inlet of the liquid storage tank 202 through a pipeline, and the end side wall of the box body 113 is provided with a flow guide groove structure matched with the end of the main shaft 101 and the end of the worm gear 103.

[0029] Among them, the housing 113, as the main structure of the gearbox, is usually cast from high-strength cast iron or aluminum alloy, with good rigidity and sealing, and can effectively accommodate and protect the internal transmission components. Its internal design is equipped with precise mounting holes and positioning structures to ensure the accurate installation and stable operation of components such as the main shaft 101 and the worm 103. The side walls of the housing 113 are provided with a guide groove structure that matches the ends of the main shaft 101 and the worm 103. This structure is used to guide the flow of coolant and achieve cooling of key components. The main shaft 101 is rotatably mounted in the middle position inside the housing 113 and is supported by high-precision bearings to ensure that it can rotate smoothly and stably. The main shaft is generally made of high-quality alloy steel, heat-treated and precision-machined, with high strength and wear resistance to withstand the torque and load during the transmission process. A worm wheel 102 is fixedly connected to the middle side wall of the main shaft 101 for meshing transmission with the worm 103 to achieve speed and torque conversion. The worm gear 102 is fixedly connected to the middle side wall of the main shaft 101 and rotates synchronously with the main shaft. The worm gear is usually made of a friction-reducing material such as bronze. Its tooth profile is precisely designed and processed, and its meshing precision with the worm 103 is high, which can effectively transmit power, while also having good transmission stability and low noise. The worm 103 is rotatably mounted on the inner side wall of the housing 113 and is connected to the housing via a bearing. The worm is generally made of high-strength alloy steel and its surface is hardened to improve its wear resistance and transmission efficiency. A secondary bevel gear 104 is fixedly connected to the side wall of the worm 103, which is used to mesh with the main bevel gear 106 to achieve power input and change of direction. The upper side wall of the worm 103 meshes with the worm gear 102, transmitting power to the main shaft 101 through a worm transmission. The secondary bevel gear 104 is fixedly connected to the side wall of the worm 103 and rotates synchronously with the worm. The secondary bevel gear has a conical tooth profile, and its meshing with the primary bevel gear 106 enables orthogonal power transmission, changing the direction of power transmission to meet different transmission requirements. The drive shaft 105 is rotatably mounted on the side wall of the housing 113 and is rotatably connected to the housing via a bushing 111. The drive shaft is generally manufactured from high-quality alloy steel, offering high strength and rigidity, and is used to input external power. A primary bevel gear 106 is fixedly connected to the end of the drive shaft 105. This meshing connection with the secondary bevel gear 104 transmits the drive shaft's power to the worm 103. The primary bevel gear 106 is fixedly connected to the end of the drive shaft 105 and rotates synchronously with the drive shaft. The primary bevel gear's tooth profile matches that of the secondary bevel gear 104, resulting in high meshing precision, enabling efficient power transmission and ensuring transmission reliability and stability. A cover plate 201 is mounted on the end of the housing 113. It is generally made of sheet metal and connected to the housing via bolts or sealant, serving to seal the housing and accommodate other components.A liquid pump 203 is mounted at the end of the cover plate 201 for pumping and delivering the cooling liquid to the parts that need to be cooled. A sleeve 204 for mounting the sensor is mounted on the inner wall of the cover plate 201 for mounting the temperature sensor to monitor the temperature of the key parts inside the gear box. The liquid storage tank 202 is fitted on the side wall of the box body 113 for storing the cooling liquid. The liquid storage tank is generally made of plastic or metal material and has a certain volume and strength to meet the demand for cooling liquid during the operation of the equipment. The liquid pump 203 is mounted at the end of the cover plate 201 and communicates with the liquid storage tank 202 through a pipeline. The liquid pump is generally a centrifugal pump or a gear pump with sufficient head and flow to pump the cooling liquid in the liquid storage tank and deliver it to the parts that need to be cooled, such as the main shaft 101 and the worm 103. The sleeve 204 for mounting the sensor is mounted on the inner wall of the cover plate 201 and extends to the side wall of the end of the worm 103. The sleeve for mounting the sensor is generally made of metal or high-temperature resistant plastic and is hollow inside for mounting the temperature sensor. The temperature sensor can accurately measure the temperature of the end of the worm 103 through the sleeve for mounting the sensor to provide data support for the operation state monitoring of the equipment. The return pipe 205 is mounted on the side wall of the main shaft 101 and communicates with the liquid inlet of the liquid storage tank 202 through a pipeline at the end. The return pipe is used to return the cooled cooling liquid to the liquid storage tank to realize the circulation of the cooling liquid. The return pipe is generally made of metal or corrosion-resistant plastic and has certain strength and corrosion resistance to ensure smooth return of the cooling liquid.

[0030] Specifically, the gear box assembly 100 further comprises a bearing 107 fitted and mounted at the end of the main shaft 101 and the worm 103, and the bearing 107 is sealed and mounted below the cover plate 201.

[0031] Among them, the bearing 107 is fitted and mounted at the end of the main shaft 101 and the worm 103, and adopts a rolling bearing with good sealing performance, such as a deep groove ball bearing or an angular contact ball bearing. The bearing is installed below the cover plate 201, which can provide support for the shaft and ensure the stability of its rotation. On the other hand, the good sealing performance can prevent the leakage of lubricating oil and the intrusion of foreign matters from the outside, prolonging the service life of the bearing.

[0032] Further, the gear box assembly 100 further comprises a sleeve ring 108 fixedly connected to the side wall of the upper end of the box body 113, and a sealing ring 109 fixedly connected to the inner wall of the sleeve ring 108, the sleeve ring 108 is sleeved on the outer side of the main shaft 101, and the sealing ring 109 is sealingly sleeved on the side wall of the main shaft 101.

[0033] The sleeve ring 108 is fixedly connected to the upper side wall of the box body 113 and sleeved outside the main shaft 101. The sleeve ring is generally made of metal material and serves to assist in supporting and positioning the main shaft and provides a mounting base for the sealing ring 109. The sealing ring 109 is fixedly connected to the inner wall of the sleeve ring 108 and is sleeved on the side wall of the main shaft 101. The sealing ring is generally made of rubber or fluororubber and has good elasticity and sealing performance, which can effectively prevent leakage of lubricating oil and ensure the lubricating environment inside the gear box.

[0034] Further, the gear box assembly 100 further comprises a rotating rod 110 fixedly connected to the end of the main shaft 101, and the end of the rotating rod 110 is mounted above the sleeve ring 108.

[0035] The rotating rod 110 is fixedly connected to the end of the main shaft 101 and is mounted above the sleeve ring 108. The rotating rod is generally a metal rod, which facilitates manual rotation of the main shaft by an operator and facilitates equipment debugging, maintenance and other operations.

[0036] Preferably, the gear box assembly 100 further comprises a shaft sleeve 111 sealingly connected to the side wall of the box body 113, and the driving shaft 105 is rotatably mounted in the inner wall of the shaft sleeve 111.

[0037] The shaft sleeve 111 is sealingly connected to the side wall of the box body 113, and the driving shaft 105 is rotatably mounted in the inner wall of the shaft sleeve 111. The shaft sleeve is generally made of copper alloy or engineering plastic and has good wear resistance and self-lubricating performance, which can reduce the friction between the driving shaft and the box body, ensure smooth rotation of the driving shaft, and simultaneously serve as a sealing function to prevent leakage of lubricating oil.

[0038] It should be noted that the gear box assembly 100 further comprises a maintenance plate 112 fixedly connected to the bottom of the box body 113, and the maintenance plate 112 is in abutment with the bottom bearing of the main shaft 101.

[0039] The maintenance plate 112 is fixedly connected to the bottom of the box body 113 and is in abutment with the bottom bearing of the main shaft 101. The maintenance plate 112 is generally made of metal plate material and is connected to the box body by bolts or buckles, which facilitates disassembly. During equipment maintenance and repair, the maintenance plate 112 can be opened to check, replace or lubricate the bottom bearing and other components of the main shaft.

[0040] Preferably, the cooling assembly 200 further comprises a plug 206 mounted on the side wall of the liquid storage tank 202, and the end of the plug 206 is sealingly inserted into the middle of the through hole in the bottom of the liquid storage tank 202.

[0041] The plug 206 is installed on the side wall of the liquid storage tank 202 and is inserted into the through hole in the bottom of the liquid storage tank 204. The plug 206 is generally made of rubber or plastic and has good sealing performance to prevent leakage of the cooling liquid. When it is necessary to discharge the cooling liquid or to maintain the liquid storage tank, the plug 206 can be opened.

[0042] In use, external power is input through the drive shaft 105, and the main bevel gear 106 at the end of the drive shaft is engaged with the auxiliary bevel gear 104 on the worm 103 to transmit power to the worm 103 to rotate the worm. The upper end of the worm 103 is engaged with the worm gear 102 to drive the main shaft 101 to rotate, realizing the transmission of power and the conversion of rotation speed and torque to meet the working requirements of the device.

[0043] The liquid pump 203 is started to pump the cooling liquid in the liquid storage tank 202 to the guide groove structure at the end of the side wall of the box 113 through the pipeline. The cooling liquid flows along the guide groove to the parts that need to be cooled, such as the main shaft 101 and the worm 103, to absorb the heat generated by these parts during operation, thereby cooling the key parts of the gear box. The cooled cooling liquid is returned to the liquid storage tank 202 through the return pipe 205 to complete the circulation cooling process of the cooling liquid.

[0044] The temperature sensor installed in the sleeve 204 for installing the sensor monitors the temperature of the end of the worm 103 in real time and transmits the temperature signal to the control system. The control system adjusts the working state of the liquid pump 203 according to the preset temperature threshold. When the temperature is too high, the control system increases the flow of the liquid pump 203 to enhance the cooling effect; when the temperature is normal, the liquid pump 203 remains in a normal working state to ensure that the gear box always operates in an appropriate temperature range.

[0045] In summary, the circulation of the cooling liquid driven by the liquid pump can quickly and effectively remove the heat generated by the key parts of the gear box during operation, ensuring the stable operation of the gear box in a high-temperature environment and improving the reliability and service life of the device. The temperature sensor installed in the sleeve for installing the sensor can monitor the temperature of the end of the worm in real time and accurately, providing intuitive data support for the operating state of the device, so that the operator can adjust the working state of the cooling system in a timely manner to avoid damage to the device due to high temperature. The sealing design of the bearing, the sealing ring and the bushing effectively prevents the leakage of lubricating oil and the intrusion of external impurities, ensuring good lubrication and working environment inside the gear box and prolonging the maintenance period of the device. The design of the maintenance plate and the plug facilitates the inspection, maintenance of the internal parts of the device and the discharge of the cooling liquid and the cleaning of the liquid storage tank, reducing the difficulty and cost of maintenance of the device.
