Description

Technical Field

[0001] This invention relates to the field of speed reducer technology, specifically to an energy-saving high-temperature protection system for gear reducers. Background Technology

[0002] Gear reducers are transmission components that rely on the meshing of gears to reduce speed and amplify output torque. They are widely used in industrial equipment such as high-temperature processing and high-temperature conveying. They are mainly used to match the speed parameters between the power source and the load, and to improve the output torque of the equipment. They are an indispensable core transmission device in industrial production.

[0003] Existing conventional gear reducers lack dedicated heat insulation structures. When operating under high-temperature conditions for extended periods, external heat is continuously conducted into the gearbox, causing the lubricating oil to easily oxidize and fail, resulting in a significant reduction in lubrication effectiveness. Under high-temperature environments, gears, hubs, and shafts expand due to heat, leading to deviations in gear meshing clearances and increasing the risk of uneven wear and jamming. This significantly increases transmission friction losses and energy consumption. Traditional reducers lack integrated self-circulating lubrication structures, requiring separate lubrication pumps and increasing the power consumption of auxiliary equipment. Furthermore, conventional reducers lack targeted residual torque buffering structures. When the equipment is powered off, the torsional impact force generated by the load directly acts on the gears, making them more susceptible to plastic deformation and damage under high-temperature conditions. This results in a high failure rate, frequent maintenance, and parts replacement, further increasing operating costs and failing to meet the demands for stable operation at high temperatures and energy conservation.

[0010] Preferably, the surface of the oil channel is provided with a dispersion groove, the top of the outer ring inside the oil groove is provided with a fine hole, the top of the oil tank is provided with a lubricating oil filling port, and the top of the lubricating oil filling port extends out of the heat insulation shell.

[0011] Preferably, the outer surface of the floating hub is provided with a plurality of splines, which are matched with the inner walls of the corresponding planetary rings and sun rings, and the outer surface of each of the plurality of splines is provided with a compensation shim.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This gear reducer's energy-saving high-temperature protection system uses an integrated heat-insulating shell to block external high-temperature radiation. Combined with an oil slinger that is linked to the drive gear, it achieves autonomous circulation oil supply, eliminating the need for an additional lubrication motor and reducing the energy consumption of auxiliary equipment. The oil tank, oil passage, and oil receiving arc plate form a closed-loop lubrication circuit, reducing the loss of lubricating oil due to high-temperature evaporation, continuously carrying away the heat of gear meshing friction, delaying the high-temperature deterioration of lubricating oil, and enabling it to operate continuously in high-temperature environments for extended periods, reducing the frequency of lubricating oil replacement and consumable costs.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 6As shown, the energy-saving high-temperature protection system for the gear reducer in this embodiment includes a heat-insulating shell 1. The heat-insulating shell 1 isolates the external high temperature to prevent the internal gear lubricating oil from failing due to high temperature, while also reducing the internal heat loss to the outside and lowering lubrication and cooling energy consumption. An outer ring 21 is provided inside the heat-insulating shell 1. The outer ring 21 is placed inside the heat-insulating protection, resulting in less thermal expansion and preventing sudden changes in gear meshing clearance at high temperatures, which would increase friction loss. Three planetary gear rings 5 ​​are meshed and connected to the inner wall of the outer ring 21. The three planetary gears distribute the load evenly, reducing the degree of thermal deformation and wear of a single gear at high temperatures, while also reducing meshing friction resistance through split transmission, thus achieving energy saving. A sun gear ring 6 is connected to the three planetary gear rings 5. The planetary transmission structure itself has a higher transmission efficiency than ordinary gears, and combined with the heat-insulating shell 1, it suppresses high-temperature thermal expansion and gear jamming. To maintain long-term energy-efficient operation, floating hubs 24 are installed inside the three planetary rings 5 ​​and the sun ring 6. These floating hubs 24 adapt to the thermal expansion deviations of high-temperature components, eliminating hard friction and reducing additional heat generation and energy loss. Axial columns 22 are installed at the middle of the floating hubs 24 in each of the three planetary rings 5. These axial columns 22, in conjunction with a compensation structure, buffer high-temperature axial thermal expansion displacement to prevent uneven wear of the planetary gears and increased energy consumption. Floating limit components 26 are installed at one end of each of the three axial columns 22. These floating limit components 26 constrain the extreme positions of high-temperature thermal expansion, preventing gear seizure and stopping, while also buffering hard contact to reduce frictional loss. One end of each of the three floating limit components 26 is connected to the output end 2. Multiple sets of limit structures disperse high-temperature thermal stress and prevent deformation of the output shaft. To reduce transmission resistance and save energy, the floating hub 24 of the sun ring 6 has an input end 4 located at its center. The floating structure of the input end 4 ensures stable coaxiality of the input teeth at high temperatures, avoiding uneven load friction loss. The outer surface of the input end 4 has a drive tooth 20. The heat insulation shell 1 blocks external high temperatures to prevent the drive tooth 20 from softening and wearing due to high temperatures, maintaining meshing accuracy and reducing slippage energy loss. One side of the drive tooth 20 is meshed with a transmission tooth 19. The heat insulation chamber reduces the gear operating temperature, reduces thermal deformation, ensures smooth meshing, reduces impact heat generation, and achieves high-temperature energy-saving transmission. One side of the transmission tooth 19 is meshed with a drive tooth 18. The multi-stage transition gear evenly distributes the high-temperature load, avoiding local overheating and wear while reducing transmission impact loss. The drive tooth 18 is located at its center through... The rotating shaft is equipped with an oil slinger 17, which automatically circulates and sprays oil as it rotates, eliminating the need for an additional oil pump, reducing energy consumption of auxiliary equipment, and continuously removing high-temperature heat from the gears. An oil tank 10 is located on the bottom outer surface of the oil slinger 17. The sealed oil tank 10, in conjunction with the heat insulation shell 1, reduces high-temperature evaporation loss of lubricating oil, lowers the frequency of oil replenishment, saves operating costs, and is suitable for long-term high-temperature operation. An oil groove 7 is located at the top of the outer ring 21. The oil groove 7 receives circulating lubricating oil, continuously wetting the planetary gears, removing high-temperature frictional heat, and simultaneously providing uniform lubrication to reduce dry friction energy consumption. An oil channel 9 is installed inside the heat insulation shell 1 above the oil groove 7. The oil channel 9 guides the lubricating oil to flow evenly to each gear pair, preventing localized high-temperature dry friction and reducing overall transmission loss. An oil-receiving arc-shaped plate 11 is installed inside the heat insulation shell 1 above the oil channel 9.The oil-receiving arc-shaped plate 11 gathers and recirculates splashed lubricating oil, reducing oil waste and eliminating the need for frequent oil replenishment, thus meeting both high-temperature lubrication requirements and energy saving.

[0022] Specifically, several unloading clips 28 are arranged on the outer surface of the input end 4 near the position of the active tooth 20. The unloading clips 28 buffer the instantaneous impact load under high temperature and heavy load, avoid gear overload wear, and reduce energy waste caused by failure downtime. Each of the unloading clips 28 has a vertical rod 34 on its outer surface. The vertical rod 34, together with the elastic structure, offsets the additional radial stress generated by high temperature thermal expansion, prevents poor tooth surface contact, and increases friction loss. The outer surfaces of the vertical rods 34 are connected to a torsion shell 27. The torsion shell 27 houses the entire unloading buffer structure, isolates it from external high temperature, and does not affect the buffer elasticity. To achieve continuous load relief and energy saving under high-temperature conditions, a return spring 33 is connected between the upright 34 and the inside of the torsion shell 27. The return spring 33 maintains its elasticity at high temperatures and continuously buffers impact loads to avoid additional heat loss from hard contact. An inner ring 35 is rotatably connected inside the torsion shell 27. The inner ring 35 adaptively adjusts the meshing position according to the load to offset the friction increase caused by the deformation of high-temperature components. Several protrusions 30 are provided on the inner wall of the inner ring 35 near the upright 34. The protrusions 30 work with the upright 34 to relieve load in stages, reduce the instantaneous peak load of high-temperature heavy load, and reduce the plastic deformation loss of gears.

[0023] Furthermore, the outer surface of the inner ring 35 is provided with a toothed area 32. The toothed area 32, together with the adjusting tooth 31, can finely adjust the unloading buffer amplitude in real time to adapt to different high temperature load conditions and accurately control transmission loss. One side of the toothed area 32 is meshed with the adjusting tooth 31, which is controlled by a micro motor. The micro motor can complete the condition adjustment by running at low power, without the need for high-power adjustment equipment to meet the high temperature and energy-saving requirements.

[0024] Furthermore, a number of stress-relieving spring components 29 are arranged on the outer surface of the torsion shell 27. The stress-relieving spring components 29 share the axial thermal expansion stress under high temperature to prevent the shell from deforming and squeezing the gears, thus increasing friction loss. The bottom of the torsion shell 27 is rotatably connected to the stress-relieving shell 13. One end of the number of stress-relieving spring components 29 is connected to the inner wall of the stress-relieving shell 13. The double-layer stress-relieving shell isolates the external high temperature and protects the elastic performance of the springs to ensure stable buffering and energy-saving effect under high temperature.

[0025] Furthermore, a protective cover 12 is installed inside the heat insulation shell 1 outside the drive gear 18 and transmission gear 19. The protective cover 12 seals the gear transmission cavity to isolate external high-temperature dust and prevent impurities from entering, which would aggravate high-temperature wear of the gears and increase energy consumption. A top shell 16 is provided at the top of the oil tank 10. The top shell 16 matches the oil slinger 17. The top shell 16 blocks external high-temperature heat from being directly conducted to the oil tank 10, preventing the lubricating oil from deteriorating rapidly at high temperatures, extending the service life of the lubricating oil, and saving consumable costs. The top of the top shell has a notch, which corresponds to the oil receiving arc plate 11. The notch guides the high-temperature lubricating oil to flow smoothly back to the oil tank 10, ensuring continuous circulation and heat dissipation, carrying away the frictional heat of the gears and reducing high-temperature losses. An oil storage groove 15 is provided on the surface of the oil slinger 17. The oil storage groove 15 stores lubricating oil, improving the continuous lubrication under high-temperature and low-speed conditions and avoiding dry friction that would increase energy consumption.

[0026] Furthermore, the surface of the oil passage 9 is provided with a dispersion groove 8, which divides the lubricating oil flow channel and evenly delivers it to all gear pairs to avoid local high temperature and dry friction due to lack of oil, thereby reducing the overall transmission energy consumption. The top of the outer ring 21 inside the oil groove 7 is provided with a fine hole 14, which continuously supplies a small amount of oil to wet the meshing surface of the planetary gears and continuously removes high temperature frictional heat to reduce tooth surface wear. The top of the oil tank 10 is provided with a lubricating oil filling port 3, and the top of the lubricating oil filling port 3 extends out of the heat insulation shell 1. The external filling port does not require disassembling the heat insulation shell, reducing the leakage of high temperature internal heat, maintaining a constant internal lubrication environment, and reducing heat dissipation energy consumption.

[0027] Furthermore, the outer surface of the floating hub 24 is provided with several splines 23. The splines 23 transmit torque while reserving a small compensation space to offset high-temperature thermal expansion deformation and prevent the splines 23 from jamming and increasing transmission resistance. The splines 23 are matched with the inner walls of the corresponding planetary rings 5 ​​and sun rings 6. The outer surface of several splines 23 is provided with compensation shims 25. The compensation shims 25 adapt to high-temperature thermal expansion, fill the gap, eliminate hard friction of the splines 23, reduce energy loss, and adapt to long-term high-temperature operation.

[0028] Furthermore, one end of the axial column 22 extends into the interior of the floating limit assembly 26. An elastic gasket is connected between the axial column 22 and the floating limit assembly 26. The elastic gasket buffers the compressive force generated by the high temperature axial thermal expansion to prevent the planetary gear from axially shifting and wearing, thus increasing energy consumption. A compensation washer ring 2201 is connected between the outer surface of the floating limit assembly 26 and the axial column 22. The compensation washer ring 2201 offsets the high temperature dimensional changes, maintains coaxiality stability, and reduces gear meshing friction loss.

[0029] Furthermore, one end of the input end 4 extends out of the front end of the heat insulation shell 1. The external input end 4 does not damage the integrity of the heat insulation shell and continuously blocks the external high temperature from entering the interior. One end of the output end 2 extends out of the rear end of the heat insulation shell 1. The split shaft end structure reduces the conduction of high temperature heat along the shaft to the transmission interior, thereby reducing the working temperature of the gear and achieving energy-saving operation.

[0030] The usage method of this embodiment is as follows: Before use, lubricating oil is added to the oil tank 10 through the external lubricating oil filling port 3. The filling port extends directly out of the heat insulation shell 1 without disassembling the heat insulation shell, thus preserving the heat insulation capacity of the heat insulation shell 1 completely, preventing external high temperature from being conducted to the inside, and reducing the additional energy consumption caused by internal heat loss. When the equipment is running, the power is connected through the input end 4, which sequentially drives the active gear 20, transmission gear 19, and drive gear 18 to complete the power transmission. The drive gear 18 synchronously drives the oil slinger 17 to rotate synchronously. Automatic oil slinging lubrication is achieved by the operation of the equipment itself, without the need for a separate oil supply motor, reducing additional power consumption and achieving energy saving. The oil storage groove 15 on the oil slinger 17 can... Lubricating oil is retained to ensure continuous oil supply under low-speed, high-temperature conditions, avoiding dry friction due to lack of oil and increased energy consumption. The splashed lubricating oil is collected by the oil receiving arc plate 11 and flows into the oil channel 9. The dispersion groove 8 inside the oil channel 9 evenly distributes the lubricating oil. A portion flows into the oil groove 7 at the top of the outer ring 21, and then continuously and slowly wets the meshing positions of the planetary gear ring 5 and the sun gear ring 6 through the fine holes 14 on the outer ring 21, continuously carrying away the heat generated by gear friction, forming a closed-loop self-lubricating heat dissipation system, reducing the high-temperature evaporation loss of lubricating oil and reducing the frequency of lubricating oil replacement. When the equipment operates in a high-temperature environment for a long time, the various metal components expand due to heat. The floating hub 24, with the compensation shim 25, automatically compensates for the thermal expansion gap. Axial column 2 2. The elastic gasket and compensating washer ring 2201 between the floating limit component 26 and the axial thermal expansion displacement buffer the gear wear and jamming, reduce friction loss, and improve transmission efficiency under high temperature conditions. When the equipment is under high temperature and heavy load conditions for a long time, the heat insulation shell 1 isolates the external high temperature radiation, the three sets of planetary gears evenly distribute the load to reduce the force on a single tooth, the floating hub 24 is equipped with compensating washer 25 to adapt to the high temperature thermal expansion gap, and the axial column 22 is equipped with compensating washer ring 2201 to buffer axial deformation. The multiple structures work together to avoid high temperature plastic deformation of gears and increased friction loss. If the high temperature load specifications change on site, or if there is residual torsional impact force after the equipment is shut down and the power is cut off, the micro motor can be started to drive the adjustment. The meshing tooth 31 drives the inner ring 35 to rotate. The inner wall protrusion 30 of the inner ring 35 pushes the upright rod 34 outward, pushing the unloading clamp 28 to fit against the output end 2 to generate frictional damping, reduce the rotational speed of the output end 2, absorb the torsional force of power failure, and can adjust the damping force according to different high temperature working conditions to accurately control transmission loss. When the equipment is stopped for maintenance, the unloading shell 13 can be opened to clean the accumulated dust and impurities inside, so as to avoid impurities aggravating high temperature wear and increasing energy consumption. After cleaning, the reset buffer component can be put back into the high temperature production environment. The whole set of equipment relies on multiple structures such as heat insulation, self-lubrication, floating compensation and adjustable damping to continuously reduce energy consumption while operating stably under high temperature conditions, achieving the effect of energy saving.
