Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel rotary driving devices, in particular to a multi-point rotary reducer for large-component photovoltaics. Background Technique

[0002] A multi-point rotary reducer is a special speed reduction device, which is used in occasions where multiple rotation points need to work coordinately at the same time, such as a large-component photovoltaic system. After the existing multi-point rotary reducer is used for a period of time, it needs to be disassembled to apply lubricating oil. However, the disassembly process is too cumbersome and inconvenient, affecting the efficiency of applying lubricating oil to the multi-point rotary reducer. Moreover, after the lubricating oil is applied to the multi-point rotary reducer, some lubricating oil will enter other areas inside the reducer, so that the lubricating oil is not all used for lubricating the worm and the worm wheel. Therefore, we propose a multi-point rotary reducer for large-component photovoltaics. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a multi-point rotary reducer for large-component photovoltaics. By arranging an oil tank on the top of the worm wheel installation housing and installing a lubricating component for lubricating the worm wheel and the worm in the oil tank, when the multi-point rotary reducer needs to apply lubricating oil, it can be realized without disassembling the housing, improving the efficiency of applying lubricating oil to the multi-point rotary reducer; by installing a lubricating component in the oil tank, the lubricating component utilizes the characteristics of slow rotation speed and few rotations of the multi-point rotary reducer for photovoltaics. When the worm wheel rotates, the worm wheel teeth intermittently lift the top block, so that the lifting block slides upward in the lifting groove, and the oil leakage grooves sealed on both sides of the lifting block are opened, and the lubricating oil leaks from the oil leakage grooves into the worm wheel. If the worm wheel just lifts the lifting block when it stops, the oil leakage groove is sealed by the sliding plate connected by the telescopic rod on the second fixing plate under the action of the second spring to avoid too much single oil leakage. When the top block is in the gap between the worm wheel teeth, the lifting block slides downward under the action of the first spring and pushes the sliding block, so that the sliding plate loses the seal of the oil leakage groove, and the lubricating oil in the oil tank enters the oil leakage groove. However, the connection between the oil leakage groove and the lifting groove is sealed by the lifting block at this time, and waits for the worm wheel to continue working to lift the lifting block to complete the oil leakage. By this method, the worm wheel is lubricated with intermittent oil injection, reducing the waste of lubricating oil and realizing the maximum utilization of lubricating oil, and solving the problems in the background.

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution: a multi-point slewing reducer for large-component photovoltaic applications, including a worm gear installation housing 1, the bottom of the worm gear installation housing 1 is fixedly communicated with a worm installation housing 2, a slewing bearing 3 is fixedly installed inside the worm gear installation housing 1, a worm gear 4 is rotatably connected to the slewing bearing 3, a worm 10 is rotatably installed inside the worm installation housing 2 at the bottom side of the worm gear 4, the worm 10 meshes with the worm gear 4, a driving component for driving the worm 10 to rotate is installed inside the worm installation housing 2, an oil tank 6 is arranged at the top of the worm gear installation housing 1, and a lubricating component for lubricating the worm gear 4 and the worm 10 is installed inside the oil tank 6.

[0020] This multi-point slewing reducer drives the worm 10 to rotate through the driving component, thereby rotating the worm gear 4 meshing with the worm 10, so that the worm gear 4 rotates at a reduced speed under the support of the slewing bearing 3. When lubricating oil needs to be filled, it can be completed through the lubricating component installed inside the oil tank 6, without disassembling the housing, improving the filling efficiency of the lubricating oil of this reducer. The driving component includes a driving motor 16, the driving motor 16 is fixedly installed at the rear side of the worm installation housing 2, a transmission shaft 7 is rotatably penetrated between the front and rear sides at the bottom of the worm installation housing 2, the rear end of the transmission shaft 7 is fixedly connected to the output shaft end of the driving motor 16, a fourth bevel gear 15 is fixedly sleeved on the outer surface of the transmission shaft 7 inside the worm installation housing 2, a fixed plate one 12 is fixedly connected to the rear side inside the worm installation housing 2, a rotating shaft 28 is rotatably penetrated through the fixed plate one 12, a second bevel gear 13 and a third bevel gear 14 are respectively fixedly connected to the upper and lower ends of the rotating shaft 28, a first bevel gear 11 is fixedly sleeved on the outer surface of the right side of the worm 10, and the first bevel gear 11 meshes with the second bevel gear 13, and the third bevel gear 14 meshes with the fourth bevel gear 15.

[0021] When the driving component is in use, start the driving motor 16, drive the transmission shaft 7 to rotate through the driving motor 16, and then drive the rotating shaft 28 to rotate, and then drive the worm 10 to rotate. Moreover, the transmission shaft 7 can be connected to multiple slewing reducers, realizing synchronous rotation of multiple rotation points in the large-component photovoltaic by a single driving source.

[0022] The lubrication assembly includes a lifting groove 17 which is arranged at the bottom of the fuel tank 6. A lifting block 18 is slidably connected to the lifting groove 17. A top block 20 is fixedly connected to the bottom side of the lifting block 18. A number of first springs 19 are fixedly connected between the top side of the lifting block 18 and the top side of the lifting groove 17. Limiting plates 29 are fixedly connected to the bottom of the left and right sides of the lifting groove 17, and the top side of the limiting plate 29 abuts against the bottom side of the lifting block 18.

[0023] Leakage oil grooves 21 are formed on the left and right sides of the lifting groove 17. The leakage oil grooves 21 communicate with the fuel tank 6. Fixing plates two 26 are fixedly connected to the left and right sides of the bottom of the fuel tank 6. A telescopic rod 25 is installed on one side of the fixing plate two 26 close to the leakage oil groove 21. The other end of the telescopic rod 25 is fixedly connected to a sliding plate 24. A second spring 27 is sleeved on the telescopic rod 25. A number of connecting rods 23 are fixedly connected to one side of the sliding plate 24 close to the lifting block 18. The other end of the connecting rod 23 is fixedly connected to a sliding block 22. The sliding block 22 is slidably connected to the inner bottom side of the leakage oil groove 21, and one side of the sliding block 22 close to the lifting block 18 abuts against the lifting block 18.

[0024] An oil inlet 8 is formed at the top of the fuel tank 6. A dust-proof cover 9 is sleeved on the oil inlet 8.

[0025] When the lubrication assembly is in use, lubricating oil is filled into the fuel tank 6 through the oil inlet 8, and the fuel tank 6 is prevented from being polluted by the dust-proof cover 9. When the slewing reducer operates, the tooth plate of the worm wheel 4 jacks up the top block 20, so that the lifting block 18 slides upward in the lifting groove 17, and then the left and right sides of the lifting block 18 release the sealing of the leakage oil groove 21, so that the lubricating oil in the leakage oil groove 21 leaks out to lubricate the worm wheel 4. If the worm wheel 4 stops rotating just when it jacks up the lifting block 18, the sliding plate 24 connected to the fixing plate two 26 through the telescopic rod 25 pushes to complete the sealing of the leakage oil groove 21 under the action of the second spring 27 to avoid continuous oil leakage. When the top block 20 is located in the tooth gap of the worm wheel 4, the lifting block 18 slides downward under the action of the first spring 19 to realize the re-sealing of the leakage oil groove 21. And because the lifting block 18 pushes the sliding block 22 when sealing, the sliding plate 24 is pushed through the connecting rod 23, and the sealing at the connection between the fuel tank 6 and the leakage oil groove 21 is released, so that the lubricating oil in the fuel tank 6 enters the leakage oil groove 21, waiting for the worm wheel 4 to rotate again to jack up the top block 20, and the lifting block 18 is limited by the limiting plate 29 to avoid direct contact with the worm wheel 4.

[0026] Mounting plates 5 are fixedly installed on the left and right sides of the worm installation housing 2. A number of mounting strip holes are formed in the mounting plates 5, and the slewing reducer is fixedly installed through the number of mounting strip holes in the mounting plates 5.

[0027] Working principle: The multi-point slewing reducer drives the transmission shaft 7 to rotate through the driving motor 16, and then drives the rotating shaft 28 to rotate, and then drives the worm 10 to rotate. The transmission shaft 7 can be connected to multiple groups of slewing reducers, realizing the synchronous rotation of multiple rotating points in the large-component photovoltaic by a single driving source. By rotating the worm 10, the worm gear 4 meshing with the worm 10 is rotated, so that the worm gear 4 rotates at a reduced speed under the support of the slewing bearing 3. The lubricating oil of this reducer is filled through the oil tank 6, and the dust cover 9 is used to prevent the oil tank 6 from being polluted. When the slewing reducer operates, the tooth plate of the worm gear 4 jacks up the top block 20, so that the lifting block 18 slides upward in the lifting groove 17, and then the left and right sides of the lifting block 18 release the seal of the oil leakage groove 21, so that the lubricating oil in the oil leakage groove 21 leaks out to lubricate the worm gear 4. If the worm gear 4 stops rotating just to jack up the lifting block 18, the sliding plate 24 connected to the fixing plate two 26 through the telescopic rod 25 is pushed under the action of the spring two 27 to complete the sealing of the oil leakage groove 21 and prevent continuous oil leakage. When the top block 20 is located in the tooth gap of the worm gear 4, the lifting block 18 slides downward under the action of the spring one 19 to realize the re-sealing of the oil leakage groove 21. And because the lifting block 18 seals and jacks the sliding block 22, the sliding plate 24 is pushed through the connecting rod 23 to release the seal at the connection between the oil tank 6 and the oil leakage groove 21, so that the lubricating oil in the oil tank 6 enters the oil leakage groove 21 and waits for the worm gear 4 to rotate again to jack up the top block 20. And the lifting block 18 is limited by the limiting plate 29 to avoid direct contact with the worm gear 4. By this method of filling lubricating oil, there is no need to disassemble the housing, which improves the filling efficiency of the lubricating oil of this reducer, reduces the waste of lubricating oil, maximizes the utilization of lubricating oil, and enables the lubricating oil to be evenly smeared on the tooth blocks of the turbine 4, improving the transmission performance of this slewing reducer.
