Description

Technical Field

[0001] The present invention relates to the technical field of planetary gearboxes, and in particular to a high-power internal helical gear planetary gearbox. Background Art

[0002] A planetary gearbox, also known as an epicyclic gear transmission mechanism and a planetary gearbox, is a gear transmission system characterized by gears rotating around a central axis like planets around a star. It mainly consists of a sun gear, planet gears, a planet carrier and an inner ring gear.

[0003] In existing high-power internal helical planetary gearboxes, the helical planetary gears continuously mesh with each other during operation. Under high-power conditions, the meshing rotation of the gears will generate significant friction, so lubricating oil is needed to effectively reduce friction. However, traditional lubrication methods usually use oil pool immersion, that is, the splashing oil generated by the rotation of the gears covers the tooth surface and bearings. However, in such systems, some helical planetary gears cannot be actively immersed, and their surfaces can only be contact-lubricated by the splashing oil driven by other gears. Especially under high-speed rotation conditions, the centrifugal force generated will throw the lubricating oil away from the key meshing areas and bearing parts, resulting in localized insufficient lubrication and uneven distribution of the lubricating oil.

[0004] Therefore, we propose a high-power internal helical planetary gearbox to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the high-power internal helical planetary gearbox is in operation, the multiple gears inside it mesh and rotate, driving the first piston and the second piston to move. When the first piston and the second piston move, they absorb the lubricating oil in the oil tank into the corresponding first fixed cylinder and the second fixed cylinder. The lubricating oil flows from the first rubber plug and the second rubber plug on the first fixed cylinder and the second fixed cylinder to the area where the gears mesh with each other, thereby ensuring that the gears can effectively contact with the lubricating oil during rotation and meshing to reduce friction. This solves the problem in the prior art that splashing oil generated by the rotation of the gears covers the tooth surface and the bearing, resulting in local insufficient lubrication and uneven distribution of lubricating oil.

[0017] 2. When the high-power internal helical planetary gearbox is in operation, it will drive the fourth rotating block to move. When the fourth rotating block moves, it will drive the moving block to move. The moving block will drive the third piston to move along the inner wall of the pipe, thereby attracting the lubricating oil outside the oil tank into the inside of the oil tank to continue lubricating the gears. This ensures that the oil level in the oil tank is always sufficient, providing uninterrupted lubrication for the internal helical planetary gears and bearings, and ensuring a continuous supply and replenishment of lubricating oil.

[0018] 3. When the high-power internal helical planetary gearbox is in operation, the third piston moves on the inner wall of the pipe to generate suction, thereby sucking the external lubricating oil into the pipe. At this time, some lubricating oil will be located inside the pipe, and the second spring will push the third piston to move again in the pipe. Later, when the third piston moves on the inner wall of the pipe again to generate suction to suck the external lubricating oil into the pipe, the pressure of the lubricating oil already inside the pipe will be increased. At this time, the lubricating oil will move the gasket to flow from the multiple circular holes on the first fixed block into the oil tank. When the lubricating oil flow is completed, the first spring will push the gasket to move on the inner wall of the first fixed block to prevent the lubricating oil in the oil tank from flowing into the pipe, thereby effectively preventing the lubricating oil in the oil tank from flowing back into the oil suction pipe and preventing backflow.

One end of the three second oil pipes 319 is fixedly connected to the outer surface of the three oil tanks 304 and extends into the interior.

[0023] In this embodiment, when a high-power internal helical planetary gearbox is in operation, the external rotating mechanism drives the input shaft 201 to rotate. When the input shaft 201 rotates, it drives the sun gear 202 to rotate. When the sun gear 202 rotates, it drives the three planetary gears 203 located on the outside to engage and rotate. The outer surfaces of the three planetary gears 203 engage and rotate along the inner wall of the inner gear ring 204. At the same time, when the three planetary gears 203 rotate, they also drive the first rotating shaft 205 to rotate. One end of the first rotating shaft 205 rotates along the inner wall of the first rotating block 206. When the first rotating block 206 rotates, it drives the output shaft 207 to rotate. When the output shaft 207 rotates and moves, it drives the external components to rotate. At the same time, the first rotating block 2 The outer surface of the other end of 06 will rotate and move along the inner wall of the second rotating block 302, driving the second rotating block 302 to move. When the second rotating block 302 moves, it will drive the lubrication component 3 and the circulation component 4 to rotate and move along with the planetary gear 203. When the first rotating shaft 205 rotates and moves, it will drive the corrugated block 305 to rotate and move. When the corrugated block 305 rotates and moves, it will simultaneously drive the outer surfaces of the first moving rod 311 and the second moving rod 317 to slide along the inner wall of the corrugated block 305 to move vertically on the outer surface of the planetary gear 203. When the first moving rod 311 moves vertically, it will drive the first moving column 310 to move. The outer surface of the first moving column 310 will slide along the inner wall of the first rotating disk 301. At the same time, the first moving rod When moving, 311 will drive the first piston 309 to move, and the outer surface of the first piston 309 will slide along the inner wall of the first fixed cylinder 307. When the first piston 309 slides on the inner wall of the first fixed cylinder 307 and generates suction, it will generate suction on the inside of the oil tank 304 through the inside of the first oil pipe 318, and the lubricating oil in the oil tank 304 will flow into the inside of the first fixed cylinder 307. Then, the first piston 309 slides on the inner wall of the first fixed cylinder 307 to generate thrust, and the lubricating oil in the first fixed cylinder 307 will flow through the inside of the first rubber stopper 308 to the meshing area of ​​the sun gear 202 and the planetary gear 203, lubricating them to reduce friction. At the same time, the second moving rod 317 will drive the second moving column 317 when it moves vertically. 6 moves, the outer surface of the second moving column 316 slides along the inner wall of the second rotating block 302, and the second moving rod 317 drives the second piston 315 to move when moving. The outer surface of the second piston 315 slides along the inner wall of the second fixed cylinder 313. When the second piston 315 slides on the inner wall of the second fixed cylinder 313 and generates suction, it generates suction to the inside of the oil tank 304 through the inside of the second oil pipe 319, sucking the lubricating oil in the oil tank 304 into the inside of the second fixed cylinder 313. Then, the second piston 315 slides on the inner wall of the second fixed cylinder 313 and generates thrust, which circulates the lubricating oil in the second fixed cylinder 313 through the inside of the second rubber stopper 314 to the area where the planetary gear 203 and the inner gear ring 204 are meshed.This device incorporates a lubrication assembly 3. When the high-power internal helical planetary gearbox is in operation, the meshing rotation of its multiple gears drives the first piston 309 and second piston 315 to move. As they move, the first and second pistons 309 and 315 draw lubricating oil from the oil tank 304 into the corresponding first and second fixed cylinders 307 and 313. The lubricating oil then flows from the first and second rubber stoppers 308 and 314 on the first and second fixed cylinders 307 and 313 to the meshing areas between the gears, ensuring effective contact with the lubricating oil during rotational meshing, thereby reducing friction. This solves the prior art problem of uneven lubrication, where splashing oil generated by gear rotation covers the tooth surfaces and bearings, resulting in localized insufficient lubrication.

[0024] like Figure 1-8 As shown, the inner walls of the three oil tanks 304 are all provided with circulation components 4, and the three circulation components 4 all include a third rotating block 401. The inner walls of the three third rotating blocks 401 are respectively fixedly sleeved on the outer surfaces of the three first rotating shafts 205, and the outer surfaces of the three third rotating blocks 401 are fixedly connected to two fourth rotating blocks 402. The inner walls of the three oil tanks 304 are all fixedly embedded with two pipes 403, and the inner walls of the six pipes 403 are all fitted with third pistons 404. One end of the six pipes 403 is fixedly installed with a filter head 405, and the outer surfaces of the six third pistons 404 are all fixedly connected to moving pipes 406. One end of the six moving pipes 406 is all fixedly connected to a moving block 407. The outer surfaces of the six pipes 403 are all fixedly connected to the first fixed block 408, and the inner walls of the six first fixed blocks 408 are all fixedly connected to the column 409.

[0025] In this embodiment, a high-power internal helical planetary gearbox drives the outer surfaces of the three planetary gears 203 to mesh and rotate along the outer surface of the inner gear ring 204 when it is in operation. When the planetary gears 203 rotate, they drive the first rotating shaft 205 to rotate. When the first rotating shaft 205 rotates, it drives the third rotating block 401 located inside the oil tank 304 to rotate. When the third rotating block 401 rotates, it simultaneously drives the two fourth rotating blocks 402 to rotate. When the fourth rotating block 402 rotates, it gradually contacts the moving block 407 and then drives the moving block 407 to move. When the moving block 407 moves, it squeezes the second spring 413. At the same time, the moving block 407 drives the moving tube 406 to move. The moving tube 406 drives the third piston 404 to move. The outer surface of the third piston 404 moves along the inner wall of the pipe 403. When the third piston 404 moves, it generates suction through the filter head 405. The filter head 40 5 will filter the excess lubricating oil near the first rubber stopper 308 and the second rubber stopper 314 through the filter head 405 and flow it into the interior of the pipe 403, and then flow it into the interior of the oil tank 304 through the first fixed block 408 on the pipe 403, and then lubricate the gears again through the first oil pipe 318 and the second oil pipe 319, and rotate the lubricating oil. By setting up the circulation component 4, when the high-power internal helical planetary gearbox is running, it will drive the fourth rotating block 402 to move. When the fourth rotating block 402 moves, it will drive the moving block 407 to move. The moving block 407 will drive the third piston 404 to move along the inner wall of the pipe 403, thereby attracting the lubricating oil outside the oil tank 304 into the interior of the oil tank 304 to continue lubricating the gears, ensuring that the oil level in the oil tank 304 is always sufficient, providing uninterrupted lubrication for the internal helical planetary gears and bearings, and ensuring a continuous supply and replenishment of lubricating oil.

[0026] like Figure 1-8 As shown, the outer surfaces of the six columns 409 are slidably connected with gaskets 410, and the outer surfaces of the six gaskets 410 are respectively fitted with the inner walls of the six first fixed blocks 408. The inner walls of the six first fixed blocks 408 are respectively provided with first springs 412, one ends of the six first springs 412 are respectively fixedly connected to the inner walls of the six first fixed blocks 408, and the other ends of the six first springs 412 are respectively fixedly connected to the outer surfaces of the six gaskets 410. The outer surfaces of the six first fixed blocks 408 are respectively provided with a plurality of evenly arranged circular holes 411, and the outer surfaces of the six one-end moving blocks 407 are respectively provided with second springs 413, one ends of the six second springs 413 are respectively fixedly connected to the outer surfaces of the six moving blocks 407, and the other ends of the six second springs 413 are respectively fixedly connected to the second fixed blocks 414. The six second fixed blocks 414 are divided into two groups, and the outer surfaces of the three groups of second fixed blocks 414 are respectively fixedly connected to the inner walls of the three oil tanks 304.

[0027] In this embodiment, a high-power internal helical planetary gearbox drives the third piston 404 to move when in operation. When the third piston 404 moves, it attracts external lubricating oil into the interior of the pipe 403 through the filter head 405. At the same time, when the outer surface of the fourth rotating block 402 is no longer in contact with the outer surface of the moving block 407, the second spring 413 drives the moving block 407 to move, and the moving block 407 pushes the third piston 404 to move. The outer surface of the third piston 404 moves along the inner wall of the pipe 403, generating thrust in the pipe 403 until the third piston 404 is located at one end of the pipe 403, and then the fourth rotating block 402 is connected to the moving block 407. The trigger drives the moving block 407 to move, and the moving block 407 squeezes the second spring 413. At the same time, the moving block 407 drives the third piston 404 to move. The suction generated by the third piston 404 will circulate the excess lubricating oil near the first rubber stopper 308 and the second rubber stopper 314 into the interior of the pipe 403 again. At this time, the pressure of the lubricating oil already in the interior of the pipe 403 gradually increases, thereby moving the gasket 410. The inner wall of the gasket 410 slides along the inner wall of the column 409 and squeezes the first spring 412 at the same time. The excess lubricating oil flows into the oil tank 304 through the multiple circular holes 411 on the first fixed block 408 until the lubricating oil already in the pipe 403 is As the volume of the oil gradually decreases, the pressure on the first spring 412 gradually decreases. The elastic force of the first spring 412 drives the gasket 410 to move until the gasket 410 is located near one end of the inner wall of the first fixed block 408, thereby preventing the lubricating oil in the oil tank 304 from flowing into the pipe 403. At the same time, the third piston 404 will again suck some lubricating oil into the pipe 403 through the filter head 405. In this device, when the high-power internal helical planetary gearbox is in operation, the third piston 404 moves on the inner wall of the pipe 403 to generate suction, thereby sucking the external lubricating oil into the pipe 403. At this time, some lubricating oil will be located inside the pipe 403, and the second spring 41 3 will push the third piston 404 to move again in the pipe 403. Later, when the third piston 404 moves on the inner wall of the pipe 403 again to generate suction to suck the external lubricating oil into the pipe 403, the pressure of the lubricating oil already in the pipe 403 will be increased. At this time, the lubricating oil will move the gasket 410 to flow through the multiple circular holes 411 on the first fixing block 408 into the oil tank 304. After the lubricating oil has flowed, the first spring 412 will push the gasket 410 to move on the inner wall of the first fixing block 408, thereby preventing the lubricating oil in the oil tank 304 from flowing into the pipe 403, thereby effectively preventing the lubricating oil in the oil tank 304 from flowing back into the oil suction pipe 403, preventing backflow.

[0028] The method of use and working principle of this device: When a high-power internal helical planetary gearbox is in operation, the external rotating mechanism will drive the gears in the box body 1 to rotate, and when the gears rotate, they will drive the first rotating shaft 205 to rotate, and the first rotating shaft 205 will drive the corrugated block 305 and the third rotating block 401 to rotate and move, and the corrugated block 305 will simultaneously drive the first moving rod 311 and the second moving rod 317 to move, and the first moving rod 311 will drive the first moving column 310 to move, and the first moving column 310 will drive the first piston 309 to move, and the first piston 309 will suck the lubricating oil in the oil tank 304 into the first fixed cylinder 307 through the inside of the first oil pipe 318, and then the first piston 309 will slide on the inner wall of the first fixed cylinder 307 to generate thrust to circulate the lubricating oil in the first fixed cylinder 307 through the inside of the first rubber stopper 308 to the area where the sun gear 202 and the planetary gear 203 are meshed. At the same time, the second moving rod 317 will drive the second piston 315 to move, and the second piston 315 will suck the lubricating oil inside the oil tank 304 into the second fixed cylinder 313 through the inside of the second oil pipe 319. Then the second piston 315 slides on the inner wall of the second fixed cylinder 313 to generate thrust, and the lubricating oil in the second fixed cylinder 313 flows through the inside of the second rubber stopper 314 to the area where the planetary gear 203 and the inner ring gear 204 are meshed. The third rotating block 401 will simultaneously drive the two fourth rotating blocks 402 to rotate, and the fourth rotating block 402 will drive the moving block 407 to move, and the moving block 407 will drive the third piston 404 to move. The third piston 404 generates suction through the filter head 405 to flow the excess lubricating oil near the first rubber stopper 308 and the second rubber stopper 314 into the interior of the pipe 403, and then flows into the interior of the oil tank 304 through the first fixed block 408 on the pipe 403.
