Description

Technical Field

[0001] The invention relates to the technical field of gear boxes, in particular to a two-shaft four-gear dual-clutch bidirectional output gear box. Background Art

[0002] The gearbox is a basic transmission device and an important mechanical component with a wide range of applications. Before the gearbox is operated, a large amount of lubricating oil needs to be injected into the gearbox to ensure that all gears can be soaked in the lubricating oil, so that an oil film can be established between the gears during operation to prevent dry friction from occurring during gear teeth operation, which may cause the gearbox to fail. After the gearbox is running, only a small amount of lubricating oil is needed to establish an oil film between the gear teeth. A large amount of lubricating oil participates in the gear contact, causing the lubricating oil to heat up rapidly and keep it at a high temperature, resulting in a high temperature of the gearbox. The high temperature of the gearbox will increase the wear of the machine equipment and shorten the service life of the gearbox. In the Chinese patent with application number 202120255557.5 and name "A gearbox cooling device for an extruder", the patent uses an oil pump to suck the cooling oil in the storage box into the interior of the No. 1 box through the oil pipe, and then sprays it on the outer surface of the gear sleeve and the rotating rod after filtering to cool and lubricate the gear sleeve and the rotating rod. However, this patent only cools the lubricating oil through the heat sink. When the gearbox has been running for a long time, the heat dissipation speed of the heat sink cannot keep up with the speed of the gearbox temperature rise, and the heat dissipation effect is poor. The temperature of the gearbox continues to rise, which will increase the wear of the machinery and equipment, shorten the service life of the gearbox, and is not conducive to the continuous operation of the gearbox. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. A heat dissipation and life extension component is provided. The lubricating oil enters the cooling arc box through the traction of the oil pump, then flows through the oil discharge head and the oil injection pipe, and finally sprays out from the oil injection head. The sprayed lubricating oil creates an oil film between the gears to cool the gears. The contact area between the lubricating oil and the gears is small, which reduces the resistance of the lubricating oil to the gear rotation and improves the transmission effect. At the same time, the cooling arc box is located on the outside of the clutch flywheel housing, and the lubricating oil can also quickly cool the clutch, extending the service life of the clutch; The lubricating oil at the bottom of the inner side of the box flows through the cooling pipe and the filter cylinder into the oil collecting box at one end, and then enters the corresponding isolation hole in the concentric tube. Compared with the traditional cooling method that only relies on the heat dissipation fins, the concentric tube and the separator divide the lubricating oil into multiple strands, so that the lubricating oil flows through multiple isolation holes, increasing the contact area of ​​the lubricating oil, and can quickly cool down the lubricating oil flowing through. The gear box has a better cooling effect and a longer service life. In combination with the oil pump, the lubricating oil can be recycled; When the gearbox is vibrated, the damping spring and the damping rubber block can buffer and absorb the vibration force, reducing the damage of the vibration to the gearbox and further extending the service life of the gearbox. When the gearbox vibrates, the telescopic inner tube moves inside the telescopic outer tube, driving the upper pressure plate to squeeze the air bag of the pedal air pump. The outlet end of the pedal air pump will deliver cold air into the arc-shaped air box and spray it out from the air diffusion holes. The cold air sprayed from the air diffusion holes can blow the heat sink on the outside of the concentric tube, utilizing the vibration force, accelerating the heat dissipation speed of the heat sink, and having a better cooling effect on the gearbox. When the gearbox runs at a high power or runs for a long time, cold water is transported to the inside of the annular cover at one end through an external water pump. The cold water flows into the isolation hole corresponding to the annular cover and is discharged from the annular cover, the water branch pipe and the water main pipe at the other end. The cooling water and lubricating oil flowing through the isolation hole are distributed at intervals. Under the action of heat conduction, the cold water can quickly cool down the lubricating oil flowing through, further enhancing the cooling effect of the gearbox. The gearbox can flexibly adjust the cooling method according to its own temperature, making it more flexible to use.

[0014] 2. An enhanced heat dissipation component is provided. When the concentric tube, the separator and the heat sink alone cannot effectively cool the lubricating oil, the telescopic cylinder drives the linkage rod and the driving rotating rod to move, the extrusion spring is compressed, and the extrusion plate applies pressure to the friction plate. The extrusion plate and the friction plate fit closely together. Under the action of static friction, the driving shaft drives the driving rotating rod to rotate. Under the clamping action of the limit bar, the driving rotating rod drives the driving pulley to rotate. Under the connection and driving action of the linkage belt, the driven pulley, the main gear and the sub-gear, the driving rod drives the crossflow fan blade to rotate. The wind generated by the rotation of the crossflow fan blade blows on the surface of the heat sink, further accelerating the heat dissipation speed of the heat sink, effectively utilizing the driving force of the driving shaft, accelerating the cooling speed of the lubricating oil, further improving the cooling effect of the gear box, and extending the service life of the gear box. When the sludge inside the gear box needs to be cleaned, the cleaning screw is rotated, and the cleaning screw drives the scraper to move along the guide rod. When the scraper moves, the sludge on the bottom inner surface of the box body is pushed into the dirt box. After the sludge is cleaned, the dirt box is removed, and the lifting rod is held to push the lifting plate up to push out the sludge inside the dirt box. There is no need to disassemble the gear box to clean the sludge, which is convenient and quick.

[0015] To sum up, the heat dissipation life extension component is coordinated with the enhanced heat dissipation component, and the gearbox can flexibly adjust the cooling method according to its own temperature. The gearbox can adjust the cooling method according to temperature requirements, and can effectively allocate and utilize the driving force and water cooling of the drive shaft, making it more flexible to use.

[0020] The working principle and use process of the present invention are as follows: before the gearbox is operated, the two oil control valves 212 are opened, and the lubricating oil is poured into the oil feeding hopper 213, and the lubricating oil flows through the oil return tee pipe 222 and the oil return branch pipe 221 into the corresponding isolation hole 219 in the concentric pipe 217, and the lubricating oil delivery is stopped after the corresponding isolation hole 219 is filled with lubricating oil; When the gearbox is running, the oil control valve 212 connected to the bottom of the oil feeding bucket 213 is closed, the driving shaft 201 and the driving gear 202 rotate, the driving gear 202 drives the driven gear 204 to rotate, and the driven gear 204 drives the clutch and other mechanical components to operate, the oil pump 210 is started, and under the traction of the oil pump 210, the lubricating oil flows through the oil return branch pipe 221, the oil return tee pipe 222, the oil pump 210 and the oil inlet head 206 in sequence into the cooling arc box 205, and then flows through the oil discharge head 207 and the oil injection pipe 208, and finally sprays out from the oil injection head 209. The oil injection head 209 sprays The oil ends are respectively directed toward the meshing parts between the adjacent driving gears 202 and the driven gears 204. The sprayed lubricating oil establishes an oil film between the gears to prevent dry friction during gear teeth operation and also cool the gears. The sprayed lubricating oil directly acts on the meshing parts between the driving gears 202 and the driven gears 204. The contact area between the lubricating oil and the gears is small, which reduces the resistance of the lubricating oil to the gear rotation and improves the transmission effect. At the same time, the cooling arc box 205 is located outside the clutch flywheel housing 203. The lubricating oil can also quickly cool the clutch and extend the service life of the clutch. The lubricating oil sprayed by the oil spray head 209 cools the driving gear 202 and the driven gear 204 and then drips into the bottom of the inner side of the box body 1. The lubricating oil at the bottom of the inner side of the box body 1 flows through the cooling pipe 214 and the filter cylinder 215 into the oil collecting box 216 at one end, and finally enters the corresponding isolation hole 219 in the concentric tube 217. The concentric tube 217 and the separator 218 can divide the lubricating oil into multiple strands, so that the lubricating oil flows through multiple isolation holes 219, thereby increasing the contact area of ​​the lubricating oil. The concentric tube 217, the partition sheet 218 and the heat sink 220 are all made of copper. Under the effect of heat conduction, the lubricating oil flowing through can be quickly cooled down. Compared with the traditional cooling method that only relies on the heat sink fins, the gearbox has better cooling and a longer service life. After the lubricating oil flows through the multiple isolation holes 219, it flows through the oil collecting box 216 at the other end and enters the oil return branch pipe 221 and the oil return tee pipe 222, and finally flows through the oil pump 210 to realize the recycling of the lubricating oil. When the gearbox is running at a high power or for a long time, the concentric tube 217, the partition plate 218 and the heat sink 220 alone cannot effectively cool the lubricating oil, the telescopic cylinder 310 is started, and the output end of the telescopic cylinder 310 contracts, driving the linkage rod 311 and the driving rotating rod 302 to move, the squeezing spring 306 is compressed, and the squeezing plate 328 applies pressure to the friction plate 301. The squeezing plate 328 fits tightly with the friction plate 301, and the supporting outer tube 304 and the supporting inner rod 305 play a connecting and supporting role. Under the action of static friction, the driving shaft 201 drives the driving rotating rod 302 to rotate. Under the clamping action of the limit bar 307, the driving rotating rod 302 drives the driving pulley 30 9 rotates, a linkage belt 314 is coated between the driving pulley 309 and the driven pulley 313, thereby driving the driven pulley 313, the driven rotating rod 312 and the main gear 315 to rotate, the main gear 315 is meshed with the two sub-gears 318, thereby driving the cross-flow fan blades 317 to rotate, the wind generated by the rotation of the cross-flow fan blades 317 blows on the surface of the heat sink 220, speeding up the air flow speed outside the heat sink 220, thereby speeding up the heat dissipation speed of the heat sink 220, the driving force of the driving shaft 201 drives the cross-flow fan blades 317 to rotate, effectively utilizing the driving force of the driving shaft 201, speeding up the cooling speed of the lubricating oil, improving the cooling effect of the gear box, and extending the service life of the gear box; When the gearbox is vibrated, the damping spring 231 and the damping rubber block 228 can buffer and absorb the vibration force, the telescopic outer tube 230 and the telescopic inner tube 229 limit the telescopic direction of the damping spring 231, and cooperate with the support frame 227 to support the gearbox, thereby reducing the damage of vibration to the gearbox and further extending the service life of the gearbox. When the gearbox vibrates, the telescopic inner tube 229 moves inside the telescopic outer tube 230, driving the upper pressure plate 232 to squeeze the air bag of the pedal air pump 234, and the air bag of the pedal air pump 234 is squeezed. The outlet end of the pedal air pump 234 will transport cold air into the arc-shaped air box 235, and finally spray it out from the air diffusion hole 236. The cold air sprayed from the air diffusion hole 236 can blow the heat sink 220 on the outside of the concentric tube 217, utilize the vibration force, further accelerate the heat dissipation speed of the heat sink 220, and have a better cooling effect on the gearbox. When the gearbox is running at a high power or for a long time, and the above methods still cannot effectively cool the gearbox, the external water pump is started, and the cooling water delivered by the external water pump flows through the water branch pipe 224 at one end into the annular cover 223, and then flows into the isolation hole 219 corresponding to the annular cover 223, and finally is discharged from the annular cover 223, the water branch pipe 224 and the water main pipe 226 at the other end into the external collection water tank. The cooling water and lubricating oil flowing through the isolation hole 219 are distributed at intervals. Under the action of heat conduction, the cooling water can quickly cool the lubricating oil flowing through; The gear box can flexibly adjust the cooling method according to its own temperature, and is more flexible to use, and can effectively allocate and utilize the driving force and water cooling of the driving shaft 201; When the sludge inside the gear box needs to be cleaned, after the lubricating oil inside the gear box is released, the fixing ear 326 is rotated to move the fixing ear 326 out of the fixing frame 327, and the lifting rod 324 is held to pull the lifting plate 325 down, so that the lifting plate 325 moves to the bottom of the inner side of the dirt box 323. At this time, the scraper 321 is located at the end of the guide rod 319 away from the sewage outlet 322, and the cleaning screw 320 is rotated, and the cleaning screw 320 drives the scraper 321 along the guide rod When the scraper 321 moves, the bottom surface of the scraper 321 is attached to the inner bottom surface of the box body 1. When the scraper 321 moves, the sludge on the inner bottom surface of the box body 1 is pushed into the dirt box 323. After the sludge is cleaned, the cleaning screw 320 is rotated in the opposite direction to return the scraper 321 to its original position, and the dirt box 323 is removed. The lifting rod 324 is held and pushed to push the lifting plate 325 upward to push out the sludge inside the dirt box 323. There is no need to disassemble the gear box to clean the sludge, which is convenient and quick.
