Description

Technical Field

[0001] This utility model relates to the field of speed reducers, specifically to an integrated dustproof and heat dissipation device for speed reducers. Background Technology

[0002] A speed reducer is a power transmission device mainly used to reduce the output speed of a motor or engine while increasing the output torque to meet the needs of mechanical equipment for low-speed, high-torque operation. Its core consists of components such as gears, bearings, and housing. Speed ​​ratio adjustment is achieved through multi-stage gear meshing. Common types include gear reducers, planetary reducers, and worm gear reducers. They are widely used in industrial automation, engineering machinery, and conveying equipment. They feature stable transmission efficiency, extended equipment life, and energy saving, making them an indispensable power regulation component in modern mechanical systems. In order to ensure the dustproof effect of the gearbox, the gearbox of the existing speed reducer usually adopts a closed structure design to prevent external contaminants such as dust and impurities from entering the interior and affecting the normal operation of gears and bearings. However, although this closed structure can effectively prevent dust, it also leads to poor internal heat dissipation. During long-term high-load operation, the gear meshing friction and bearing rotation will generate a lot of heat. However, due to the sealed housing, the heat is difficult to dissipate quickly, causing the internal temperature to rise continuously. Excessive temperature will not only accelerate the aging of lubricating oil and reduce the lubrication effect, but may also cause thermal expansion of metal parts, affecting the gear meshing accuracy, and even causing abnormal wear or failure of equipment, thereby shortening the service life of the speed reducer.

[0003] In summary, to ensure the long-term stable operation of the reducer, it is necessary to address the poor heat dissipation problem caused by the sealed structure of the gearbox. This would enable the equipment to effectively dissipate heat while maintaining efficient dust prevention, thereby avoiding problems such as lubricant failure and accelerated component wear caused by excessive temperature, and further improving the reliability and service life of the reducer. Summary of the Invention

[0004] The purpose of this utility model is to provide an integrated dustproof and heat dissipation device for speed reducers. By adding a heat dissipation structure that is linked to the drive shaft on the gearbox, the heat dissipation structure can be driven to run synchronously when the drive shaft rotates, thereby improving the heat dissipation effect inside the gearbox and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated dustproof and heat dissipation device for a speed reducer, comprising a gearbox, a drive shaft connected to the gearbox, a protective component on the outside of the gearbox, an air outlet pipe fixed to the outside of the gearbox, a connecting shell installed at the end of the air outlet pipe, an air inlet pipe fixed to the outside of the connecting shell, a rotating seat rotatably connected inside the connecting shell, multiple sets of circumferentially distributed supports installed on the outside of the rotating seat, a connecting plate rotatably connected between each set of supports, a positioning groove opened inside the connecting shell, the bottom of the connecting plate being slidably connected to the positioning groove via a slider, a transmission mechanism for driving the rotating seat to rotate on the outside of the gearbox, and a dustproof mechanism located on the lower side of the gearbox.

[0006] Preferably, the protective assembly includes a protective shell fixed to the outside of the gearbox and a baffle fixed to the protective shell, the baffle being fixedly connected to the protective shell by screws.

[0007] Preferably, the transmission mechanism includes a linkage component disposed on the outside of the gearbox and a drive component disposed on the outside of the transmission shaft, wherein the drive component drives the rotating seat to rotate through the linkage component.

[0008] Preferably, the linkage assembly includes a bracket fixed to the gearbox and a rotating shaft rotatably connected to the bracket, with the top of the rotating shaft rotatably connected to the rotating seat through a connecting shell.

[0009] Preferably, the drive assembly includes a worm fixed to the outside of the drive shaft and a worm wheel fixed to the bottom of the shaft, the worm wheel meshing with the worm.

[0010] Preferably, the dustproof mechanism includes a protective component disposed on the side of the gearbox and a fixing component disposed on the protective component. The protective component is used to improve the dustproof effect of the gearbox, and the fixing component is used to position the protective component.

[0011] Preferably, the protective component includes a ventilation slot on the side of the gearbox, a fixing frame disposed inside the ventilation slot, and a mesh plate fixed inside the fixing frame, wherein the fixing frame is adapted to the ventilation slot.

[0012] Preferably, the fixing component includes multiple connectors fixed to the outside of the fixing frame, fixing screws provided on the connectors, and a connecting groove opened on the side of the gearbox, the connecting groove being adapted to the connectors.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention adds a heat dissipation structure linked to the drive shaft on the gearbox. When the drive shaft rotates, it automatically drives the heat dissipation device to operate synchronously, improving heat dissipation efficiency. This design utilizes the equipment's own operating power to achieve heat exchange, avoiding additional energy consumption while maintaining the original dustproof performance. The linked heat dissipation structure enhances airflow inside the gearbox, promoting the rapid removal of heat from heat-generating components such as gears and bearings, effectively reducing the temperature of lubricating oil and the operating temperature of metal parts. This slows down lubricating oil deterioration and reduces the impact of thermal deformation on meshing accuracy. While ensuring dustproof requirements, this solution significantly improves the reliability and service life of the reducer under continuous high-load conditions through optimized thermal management.

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] Refer to the instruction manual appendix Figures 1 to 5 A dustproof and heat dissipation integrated device for a speed reducer includes a gearbox 1, a drive shaft 2 connected to the gearbox 1, a protective component on the outside of the gearbox 1, an air outlet pipe 4 fixed on the outside of the gearbox 1, a connecting shell 5 installed at the end of the air outlet pipe 4, an air inlet pipe 6 fixed on the outside of the connecting shell 5, a rotating seat 7 rotatably connected inside the connecting shell 5, multiple sets of circumferentially distributed supports 8 installed on the outside of the rotating seat 7, a connecting plate 9 rotatably connected between each set of supports 8, a positioning groove 10 opened inside the connecting shell 5, and the bottom of the connecting plate 9 slidably connected to the positioning groove 10 through a slider, a transmission mechanism for driving the rotating seat 7 to rotate is provided on the outside of the gearbox 1, and a dustproof mechanism is provided on the lower side of the gearbox 1.

[0018] It should be noted that the drive shaft 2 drives the rotating seat 7 to rotate through the transmission mechanism. The rotating seat 7 drives multiple sets of connecting plates 9 to rotate. The slider at the bottom of the connecting plate 9 slides along the trajectory of the positioning groove 10, forcing the connecting plate 9 to produce periodic angular changes, continuously compressing the internal cavity volume of the connecting shell 5, and forcefully squeezing the gas inside the connecting seat out of the air outlet 4. The air inlet 6 is equipped with a dustproof net, which forms a forced convection circulation with the dustproof mechanism to achieve efficient heat dissipation.

[0019] Refer to the instruction manual appendix Figure 1 The protective assembly includes a protective shell 31 fixed to the outside of the gearbox 1 and a baffle 32 fixed to the protective shell 31. The baffle 32 is fixedly connected to the protective shell 31 by screws.

[0020] It should be noted that the protective component, through the combination structure of the protective shell 31 and the baffle 32, provides a physical isolation barrier for the internal transmission mechanism, effectively preventing external dust from entering the transmission mechanism.

[0021] Refer to the instruction manual appendix Figure 2 and Figure 3 The transmission mechanism includes a linkage component located outside the gearbox 1 and a drive component located outside the transmission shaft 2. The drive component drives the rotating seat 7 to rotate through the linkage component.

[0022] It should be noted that the transmission mechanism, as the power transmission hub, transmits the rotational motion of the transmission shaft 2 to the rotating seat 7 through the drive assembly and linkage assembly, thereby achieving synchronous operation of the heat dissipation structure and the transmission shaft 2.

[0023] Refer to the instruction manual appendix Figure 2 and Figure 3 The linkage component includes a bracket 111 fixed on the gearbox 1 and a rotating shaft 112 rotatably connected to the bracket 111. The top of the rotating shaft 112 is rotatably connected to the shell 5 and the rotating seat 7.

[0024] It should be noted that the linkage component transmits power between the rotating seat 7 and the drive component through the rotating shaft 112 supported by the bracket 111, ensuring stable torque transmission.

[0025] Refer to the instruction manual appendix Figure 2 and Figure 3 The drive assembly includes a worm 113 fixed to the outside of the drive shaft 2 and a worm wheel 114 fixed to the bottom of the rotating shaft 112, with the worm wheel 114 meshing with the worm 113.

[0026] It should be noted that the drive assembly utilizes the meshing characteristics of the worm gear 113 and the worm wheel 114 to convert the high-speed rotation of the transmission shaft 2 into the torque output required by the rotating shaft 112, thereby meeting the power requirements of the heat dissipation structure.

[0027] Refer to the instruction manual appendix Figure 2 and Figure 5 The dustproof mechanism includes a protective component disposed on the side of the gearbox 1 and a fixing component disposed on the protective component. The protective component is used to improve the dustproof effect of the gearbox 1, and the fixing component is used to position the protective component.

[0028] It should be noted that the dustproof mechanism filters dust from the gearbox 1 ventilation opening through protective components, while the fixing components ensure the detachability and installation stability of the protective structure.

[0029] Refer to the instruction manual appendix Figure 2 and Figure 5 The protective components include a ventilation slot 121 on the side of the gearbox 1, a fixing frame 122 disposed inside the ventilation slot 121, and a mesh plate 123 fixed inside the fixing frame 122. The fixing frame 122 is adapted to the ventilation slot 121.

[0030] It should be noted that the mesh plate 123 in the protective component covers the entire cross section of the ventilation slot 121, which not only ensures the smooth flow of air, but also physically intercepts most of the dust particles from entering the gearbox 1.

[0031] Refer to the instruction manual appendix Figure 2 and Figure 5 The fixing component includes multiple connectors 124 fixed to the outside of the fixing frame 122, fixing screws 125 provided on the connectors 124, and a connecting groove 126 opened on the side of the gearbox 1, the connecting groove 126 being adapted to the connectors 124.

[0032] It should be noted that by using fixing screws 125 to install the connector 124, the fixing frame 122 can be quickly disassembled and assembled, which facilitates the cleaning of the mesh plate 123.

[0033] Working principle: When the drive shaft 2 rotates, it drives the worm gear 113 on its outer side to rotate. The worm gear 113 meshes with the worm wheel 114 fixed at the bottom of the rotating shaft 112, driving the rotating shaft 112 to rotate. The rotating shaft 112 passes through the bracket 111 and extends into the connecting shell 5, driving the rotating seat 7 at the top to rotate. The rotating seat 7 drives the multiple sets of supports 8 distributed circumferentially on its outer side to rotate, thereby driving the connecting plate 9 installed between each set of supports 8 to move. The slider at the bottom of the connecting plate 9 slides along the trajectory of the positioning groove 10 opened inside the connecting shell 5. This constraint forces the connecting plate 9 to undergo periodic angular deflection and oscillation while revolving with the rotating seat 7. This oscillation continuously compresses and expands the volume of the internal chamber of the connecting shell 5. During the volume compression phase, the gas inside the connecting shell 5 is forcefully squeezed out and discharged through the air outlet duct 4. During the volume expansion phase, external air is drawn into the connecting shell 5 through the air inlet duct 6 equipped with a dustproof screen. At the same time, the fixed frame 122 and the screen plate 123 installed in the ventilation slot 121 on the side of the gearbox 1 allow air to exchange between the inside and outside of the gearbox 1. This forced convection circulation process uses the equipment's own power to continuously carry out the heat generated inside the gearbox 1. Combined with the dustproof screen plate 123 of the ventilation slot 121, it achieves efficient heat dissipation while maintaining the airtight and dustproof effect of the gearbox 1.
