Description

Technical Field

[0001] The invention relates to the technical field of transmission equipment, in particular to an embedded low thermal resistance transmission device. Background Art

[0002] Planetary reducer is a commonly used transmission device, which is widely used in mechanical equipment to reduce the speed of the output shaft and increase the torque. Its structure is mainly composed of outer ring gear, planetary gear, sun gear and other components. Planetary reducer is favored because of its compact structure, large transmission ratio and stable torque output. The working principle of planetary reducer is simple and clear. The planetary gear rotates through the drive of the sun gear, and the planetary gear rotates through the support of the outer ring gear, thereby reducing the speed of the output shaft and increasing the torque output. This transmission mode makes planetary reducer widely used in various mechanical equipment, such as industrial machinery, automation equipment, food processing machinery and other fields. Planetary reducer has the advantages of high transmission efficiency, stable operation and long life, which can meet the needs of different working conditions. In modern industrial production, planetary reducer plays an important role and provides reliable power support for the normal operation of mechanical equipment.

[0003] The Chinese patent with application number CN202321980771.2 discloses an embedded integrated air-cooled shell output planetary reducer. When the shaft rotates, it will drive the sun gear to rotate, thereby driving the planetary gears to rotate, and then driving the planetary carrier to rotate. When the shaft rotates, it can drive the main crankshaft gear to rotate, thereby driving the secondary crankshaft gear to rotate. Under the meshing action between the driving gear and the driven gear, it can drive the fan blades to rotate, thereby dissipating heat from the device. In this way, the fan blades are driven to rotate by their own structure, and there is no need to connect an additional power supply, which can reduce energy waste. This solves the problem that the device proposed in the above background is equipped with an air-cooled fan on the outer shell to assist it in heat dissipation, but adding a fan will increase the waste of electricity.

[0004] A Chinese patent with application number CN202323556191.3 discloses an output transmission structure of a planetary reducer. By setting a limit groove, a first electromagnet, a movable collar, a spring and a limit ball, and utilizing the interaction between the first electromagnet and the spring, the slider on the outside of the movable collar moves in the slide groove, so that the recessed portion is close to or away from the top of the storage hole, so that the limit groove or the recessed portion can be used to temporarily accommodate the limit ball, thereby completing the fixing or separation of the output shaft of the planetary reducer and the inner sleeve of the equipment, or the fixing or separation of the output shaft of the servo motor and the inner sleeve of the planetary reducer, and the disassembly and assembly process is simple and quick.

[0005] By setting a second electromagnet, a slot and a strip, when the planetary reducer body is connected to an external device and is in use, the second electromagnet is energized and the first electromagnet is de-energized. At this time, the slider is close to the second electromagnet to fix the moving collar, so as to avoid the position shift of the moving collar due to the action of the spring when there is external shock during use, thereby ensuring the stability of the connection. At the same time, the setting of the slot and the strip can form a protective shell on the outside of the fixed structure to prevent the fixed structure from accumulating dust during use. However, the following problems still exist in actual applications, specifically: 1. Most of the existing transmission mechanisms are special mechanisms with limited application scope. They are not generally applicable to industries such as lifting machinery, construction machinery, and new energy gravity energy storage, and have a narrow application scope. 2. During the operation of the planetary reducer, due to long-term operation, the gear parts will be worn, affecting the service life. At the same time, a lot of heat will be generated. If the heat is not dissipated in time, high-temperature friction will be caused, affecting the normal operation of the equipment itself; 3. When the lubricating oil is used to lubricate and dissipate heat for the planetary gear set, a small amount of impurities will be generated during the friction process, which will affect the planetary gear set during the high-frequency rotation process. It needs to be replaced regularly. At the same time, before replacement, the impurities will still affect the tooth surface accuracy. 4. When driven by a driving motor, the gravity of the heavy object will cause the drum to rotate, which will lead to the lifting being unreliable and the drum cannot be effectively locked in time.

[0031] An intermediate shaft 8 is rotatably connected inside the support frame 1. A limiting tooth groove 9 is provided on the intermediate shaft 8 and matches with the driving gear sleeve 44. The driving gear sleeve 44 and the limiting tooth groove 9 match to realize the synchronous rotation of the limiting gear rod 4 and the intermediate shaft 8, and also facilitate the separation of the planetary reduction part and the driving motor 2 for easy disassembly and assembly. The intermediate shaft 8 is placed inside the driving sleeve 6. The intermediate shaft 8 is connected to the driving gear ring 7 through a planetary gear set. The planetary gear set is placed inside the driving sleeve 6, and the reduction transmission of the driving motor 2 and the driving sleeve 6 is realized through the planetary gear set.

[0032] The driving sleeve 6 is filled with lubricating oil, and an oil filling structure and an oil discharge structure are connected to the driving sleeve 6. The oil filling structure is used to fill the driving sleeve 6 with lubricating oil, and the lubricating oil in the driving sleeve 6 is discharged to the outside through the oil discharge structure to realize the circulation of the lubricating oil. The circulation of the lubricating oil is formed by the oil filling structure and the oil discharge structure, which lubricates the planetary gear set and brings the heat generated by friction out of the driving sleeve 6. The driving motor 2 and the upper end of the support frame 1 are both connected with lifting rings, and the lifting of the support frame 1 is realized by the lifting rings.

[0033] During the specific implementation of this embodiment, the support frame 1 is first fixed to a suitable position, and then the connection between the drive motor 2 and the drive sleeve 6 is achieved through the cooperation of the limit tooth groove 9 and the limit tooth rod 4, the drive motor 2 is fixed on the support frame 1, and the oil injection structure and the oil discharge structure are started at the same time, and the drive motor 2 is started. The drive motor 2 rotates to drive the transmission shaft 3 to rotate, and the transmission shaft 3 drives the intermediate shaft 8 to rotate through the limit tooth rod 4 and the limit tooth groove 9. The rotation of the intermediate shaft 8 drives the drive sleeve 6 to rotate through the planetary gear set, and the rotation of the drive sleeve 6 drives the roller to rotate. At the same time, the oil injection structure adds lubricating oil to the inside of the drive sleeve 6, and the lubricating oil lubricates and cools the planetary gear set. At the same time, the lubricating oil is discharged from the drive sleeve 6 through the oil discharge structure after cooling and lubrication, thereby realizing the recycling of the lubricating oil.

[0034] The oil discharge structure includes a liquid return bin 10 opened on the inner wall of the drive sleeve 6. The inner wall of the drive sleeve 6 is provided with a plurality of liquid through holes 11. The lubricating oil enters the liquid return bin 10 through the liquid through holes 11 to realize the recovery of the lubricating oil. At the same time, the drive sleeve 6 rotates, and the lubricating oil flows into the liquid return bin 10 through the liquid through holes 11 under the action of centripetal force to realize the collection of the lubricating oil after lubrication. The lubricating oil inside the drive sleeve 6 flows back to the liquid return bin 10 through the liquid through holes 11.

[0035] The end of the driving sleeve 6 away from the driving motor 2 is coaxially fixedly connected with a collecting bin 12, the collecting bin 12 is connected with the liquid return bin 10, the lubricating oil in the liquid return bin 10 flows toward the collecting bin 12, the collecting bin 12 is coaxially connected with a conical collecting plate 13 at the end away from the driving sleeve 6, the lubricating oil is collected toward the axial center of the conical collecting plate 13 through the guiding effect of the conical collecting plate 13, and is continuously transported to the side of the conical collecting plate 13, the collecting bin 12 is coaxially connected with a return pipe 1 4. The return pipe 14 is rotatably connected to the collecting bin 12 to ensure that the return pipe 14 remains stationary while the driving sleeve 6 rotates. The return pipe 14 is communicated with an oil storage tank 15 connected to the support frame 1. An oil pump 16 is arranged inside the oil storage tank 15. The oil pump 16 is used to pump the inside of the collecting bin 12 to a negative pressure state. Due to the pumping action of the oil pump 16, the return pipe 14 and the collecting bin 12 are in a low pressure state, thereby allowing the lubricating oil to flow more smoothly into the oil storage tank 15.

[0036] Since the collecting bin 12 rotates synchronously with the driving sleeve 6, in order to ensure the stability of the connection between the return pipe 14 and the collecting bin 12 and to prevent the lubricating oil from leaking from the return pipe 14 and the collecting bin 12, an auxiliary sealing structure is provided. Specifically, on the basis of the existing sealing structure, an auxiliary sealing structure is connected between the return pipe 14 and the collecting bin 12, and the auxiliary sealing structure includes a connecting sleeve 17 coaxially fixedly connected to the collecting bin 12, an annular sealing rail 18 is provided inside the connecting sleeve 17, an adjusting ring 19 is coaxially rotatably connected inside the annular sealing rail 18, the adjusting ring 19 is fixedly connected to the return pipe 14, and the outer wall surface of the adjusting ring 19 and The inner wall surface of the annular sealing rail 18 fits together, the adjusting ring 19 and the return pipe 14 are coaxially fixedly connected, annular rails 20 are provided at both ends of the adjusting ring 19, and a sealing ring plate 21 is coaxially slidably connected inside the annular rail 20. The sealing ring plate 21 and the annular rail 20 are connected by a spring, and the wall surface of the sealing ring plate 21 fits together with the inner wall of the annular sealing rail 18. The sealing ring plate 21 is made of elastic material. Under the action of the spring, the sealing ring plate 21 always fits closely together with the inner wall surface of the annular rail 20. Even if there is long-term rotation wear, under the action of the spring, the sealing ring plate 21 automatically compensates and always fits together with the inner wall surface of the annular rail 20.

[0037] In order to realize the injection of lubricating oil into the interior of the driving sleeve 6 and ensure the circulation of the lubricating oil, the oil injection structure includes an injection pipe 22 connected to the oil storage tank 15, the injection pipe 22 is connected to the discharge end of the oil pump 16, the extracted lubricating oil is circulated into the interior of the driving sleeve 6 through the oil pump 16, the injection pipe 22 passes through the axis of the return pipe 14, the injection pipe 22 and the driving sleeve 6 are rotatably connected, ensuring that the driving sleeve 6 and the injection pipe 22 Independent movement, the inner diameter of the reflux pipe 14 is larger than the outer diameter of the injection pipe 22, the injection pipe 22 passes through the collection bin 12 and is placed inside the driving sleeve 6, the injection pipe 22 is placed on one end of the driving sleeve 6 and is fixedly connected with an atomizing nozzle 23, the atomizing nozzle and the driving sleeve 6 are rotatably connected, the lubricating oil inside the oil storage tank 15 is sprayed into the driving sleeve 6 through the injection pipe 22 and the atomizing nozzle 23, thereby achieving lubrication and cooling of the planetary gear set.

[0038] During the transmission process between gears, wear will occur and some impurities will be mixed in the lubricating oil. If the lubricating oil is not purified for a long time, the gear tooth surface will be aggravated. Therefore, a structure for filtering and purifying the lubricating oil is provided. Specifically, a filter plate 24 is fixedly connected to the inside of the oil storage tank 15, and the lubricating oil is filtered through the filter plate 24. One side of the oil storage tank 15 is fixedly connected to a collecting box 25, and the filtered impurities are collected through the collecting box 25.

[0039] The long-term accumulation of filter residues will cause the filter plate 24 to be blocked, so a structure for cleaning the filter plate 24 is provided. Specifically, a scraper 26 is slidably connected to the upper end of the filter plate 24, and the scraper 26 is threadedly connected to a reciprocating screw rod 27 rotatably connected to the inside of the oil storage tank 15. The reciprocating screw rod 27 is externally connected to a driving source, and the reciprocating sliding of the scraper 26 is driven by the rotation of the reciprocating screw rod 27. In the process of the reciprocating sliding of the scraper 26, the cleaning of the filter plate 24 is achieved. A storage rail 28 is provided on one side of the collection box 25 close to the oil storage tank 15, and an isolation plate 29 is slidably connected to the storage rail 28. The isolation plate 29 and the storage rail 28 are connected by a spring. The isolation plate 29 is inclined at one end close to the oil storage tank 15. The impurities cleaned by the scraper 26 are collected by the storage rail 28. At the same time, the isolation plate 29 slides up and down in the process of the isolation plate 29 also realizing the isolation between the oil storage tank 15 and the storage rail 28. Only when the scraper 26 slides to one side of the storage rail 28, the isolation plate 29 slides downward, thereby facilitating the impurities to enter the interior of the storage rail 28. At the same time, when the scraper 26 slides to the inner chamber of the oil storage tank 15, the isolation plate 29 rises to realize the isolation between the oil storage tank 15 and the storage rail 28.

[0040] In order to prevent the scraper 26 from scraping the lubricating oil retained on the filter plate 24 into the inside of the receiving rail 28 during the sliding process, a new scraper 26 structure is provided to prevent the impurities from accumulating on the side away from the receiving rail 28 during the reciprocating sliding process of the scraper 26. Specifically, a plurality of oil holes 30 are provided on the scraper 26 to allow the lubricating oil to pass through the scraper 26 smoothly. The scraper 26 includes a main frame 31, and the main frame 31 is threadedly connected to the reciprocating screw rod 27. A rotating filter plate 32 is rotatably connected to the main frame 31. The rotating filter plate 32 and the main frame 31 are connected by a torsion spring. A limiting baffle 33 is fixedly connected to the main frame 31, and the rotating filter plate 32 is limited by the limiting baffle 33. At the same time, the end of the filter plate 24 away from the storage rail 28 is fixedly connected to a wedge-shaped stopper 42, so that when the scraper 26 slides toward the side of the storage rail 28, the rotating filter plate 32 is always in a vertical contact state with the filter plate 24 under the limiting action of the limiting baffle 33. When the scraper 26 slides away from the storage rail 28, the rotating filter plate 32 rotates under the action of the wedge-shaped stopper 42, so that the impurities can pass through the scraper 26 to the side of the scraper 26 close to the storage rail 28.

[0041] In order to achieve the locking of the reel 5 and prevent the reel 5 from slipping and rotating under the action of a heavy object, the present embodiment provides a structure for locking the reel 5, wherein both ends of the reel 5 are fixedly connected to a limit ring 34, and a limit clamping ring 35 is coaxially slidably connected inside the limit ring 34, and an electromagnet 41 is fixedly connected inside the limit ring 34, and the limit clamping ring 35 is adsorbed by the electromagnet 41, and a plurality of limit holes 36 distributed on a circular axis are opened on the limit clamping ring 35, and a limit frame 37 is fixedly connected to the support frame 1, and two limit frames 37 are fixedly connected to the limit frame 37. A symmetrically distributed limit pin 38 is used to limit the reel 5 through the cooperation of the limit pin 38 and the limit hole 36. When the electromagnet 41 is energized, the limit snap ring 35 is adsorbed and received in the limit ring 34, so that the limit pin 38 and the limit hole 36 are disengaged and the reel 5 is unlocked. At the same time, when the reel 5 stops rotating, the electromagnet 41 is powered off, the limit snap ring 35 is reset, and the limit pin 38 and the limit hole 36 cooperate to lock the limit snap ring 35.

[0042] The limit pin 38 includes a limit sleeve 39, and the limit sleeve 39 is internally coaxially slidably connected to the limit pin 40. The limit pin 40 and the limit sleeve 39 are connected by a spring. The elastic force between the limit pin 40 and the limit sleeve 39 is smaller than the elastic force of the spring between the limit clamping ring 35 and the limit ring 34, thereby avoiding the problem of jamming between the limit pin 38 and the limit clamping ring 35.

[0043] When the present invention is used in practice, the support frame 1 is first fixed to a suitable position, and then the connection between the driving motor 2 and the driving sleeve 6 is realized through the cooperation of the limiting tooth groove 9 and the limiting tooth rod 4, and the driving motor 2 is fixed on the support frame 1, and the oil filling structure and the oil discharge structure are started at the same time, and the driving motor 2 is started. The driving motor 2 rotates to drive the transmission shaft rod 3 to rotate, and the transmission shaft rod 3 drives the intermediate shaft 8 to rotate through the limiting tooth rod 4 and the limiting tooth groove 9. The rotation of the intermediate shaft 8 drives the driving sleeve 6 to rotate through the planetary gear set, and the rotation of the driving sleeve 6 drives the roller to rotate. At the same time, the atomizing nozzle 23 fills lubricating oil into the driving sleeve 6, and the lubricating oil lubricates and cools the planetary gear set. At the same time, after cooling and lubrication, the driving sleeve 6 is discharged through the return pipe 14 and enters the collection box 25. The lubricating oil entering the collection box 25 is filtered through the filter plate 24, and then recycled by the oil pump 16. At the same time, the impurities on the filter plate 24 are cleaned by the rotation of the reciprocating screw 27 to ensure the cleanliness of the lubricating oil circulation process.
