Description

TECHNICAL FIELD

[0001] The present application relates to the field of speed reducer, in particular to a lubricating system of textile machinery speed reducer BACKGROUND

[0002] Textile machinery is a kind of machinery and equipment needed to process natural fibers or chemical fibers into various textiles.

[0003] Textile machinery has strong process, complex structure and many types of parts, and various processing procedures. Moreover, textile machinery and many other industrial products are interdependent and mutually promoting, for example, textile machinery needs motor industry to provide special function matching motor, textile special motor that can withstand harsh environment, and petroleum chemical industry to provide oil-resistant synthetic resin that can not deform for long-term immersion in lubricating oil to make transmission parts or sealing parts. Among them, the speed reducer is also an indispensable part of the textile machinery.

[0004] However, with the continuous development of industry, textile machinery also requires higher efficiency. With the continuous development of automation and intelligentization, the disadvantages of traditional speed reducer begin to emerge. The traditional speed reducer is a closed box type structure, which produces oil leakage after a period of work. Because the closed box type structure cannot observe the internal lubricating oil content of the speed reducer, it often cannot be maintained in time, which causes the lack of lubrication between the gears and bearings in the speed reducer, causing damage to the parts, and even in serious cases, the entire speed reducer will be scrapped. The traditional box type speed reducer needs to stop working and disassemble the speed reducer to add lubricating oil, which greatly affects the working efficiency of the textile machinery and greatly affects the continuity of the textile process.

[0005] Therefore, it has obvious significance to study a lubricating system of textile machinery speed reducer, which can conveniently and quickly observe the internal lubricating oil content of the speed reducer, prevent the speed reducer from lacking internal lubricating oil due to oil leakage, filter the lubricating oil containing iron filings or other impurities in the speed reducer, and conveniently and quickly supplement the lubricating oil while the speed reducer is working.

[0026] The application will be further described below in connection with specific embodiments. The illustrative embodiments of the application and the description used to explain the application are not intended to be limiting.

[0027] As shown in Figure 1 , Figure 2 , the lubrication system of the textile machinery speed reducer is placed on the mounting plate 11. The mounting plate 11 is welded with a side seal 11.1 around the periphery. The mounting plate 11 is welded with a first mounting bracket 11.2 on the inner side, and a second mounting bracket 11.3 on the outer side. The mounting plate 11 is fixedly connected with the speed reducer 1 through the second mounting bracket 11.3. Two triangular reinforcing ribs are welded between the second mounting bracket 11.3 and the mounting plate 11 to improve the connection strength. The first shell 5 of the lubrication system of the textile machinery speed reducer is locked on the side seal 11.1 by a plurality of screws. The side seal 11.1 and the first shell 5 can play a dustproof sealing role.

[0028] As shown in Figure 1 , , the first adapter assembly 2 is installed at the top of the speed reducer 1 at the hanging ring screw hole. The first oil pipe 3, the breather pipe 4, and the lubrication system are connected on the first adapter assembly 2. The second adapter assembly 10 is installed at the bottom of the speed reducer 1 at the oil discharge threaded hole. The second oil pipe 8, the third oil pipe 9, and the lubrication system of the textile machinery speed reducer are connected on the second adapter assembly 10.

[0029] Figure 1 and Figure 3As shown, the first housing 5 is externally mounted with a transparent tube 6. The transparent tube 6 is made of transparent glass material, and has a relatively hard texture and will not deform. The upper end of the transparent tube 6 is connected to the first adapter assembly 2 at the upper end of the speed reducer 1 through the air pipe 4, so that the air pressure in the transparent tube 6 is consistent with the air pressure in the speed reducer 1. The lower end of the transparent tube 6 is connected to the second adapter assembly 10 at the lower end of the speed reducer 1 through the third oil pipe 9, so that the lubricating oil level in the transparent tube 6 is consistent with the lubricating oil level in the speed reducer 1.

[0030] As shown in the drawings, Figure 3 The transparent tube 6 is internally placed with a hollow steel ball 20, which has a density lower than that of the lubricating oil, so that the hollow steel ball 20 can float on the surface of the lubricating oil. Because the lubricating oil level in the transparent tube 6 is consistent with the lubricating oil level in the speed reducer 1, the height of the lubricating oil contained in the speed reducer 1 can be determined by observing the position of the hollow steel ball 20 floating above the lubricating oil level in the transparent tube 6. The bottom of the transparent tube 6 is provided with a first terminal 6.1 and a second terminal 6.2. The first terminal 6.1 and the second terminal 6.2 are made of hard and conductive metal material. The upper ends of the first terminal 6.1 and the second terminal 6.2 slightly extend into the interior of the transparent tube 6, and the lower ends of the first terminal 6.1 and the second terminal 6.2 are connected to the electrical box 15 through electric wires. The connection parts of the first terminal 6.1, the second terminal 6.2 and the transparent tube 6 are in a sealed state to prevent oil leakage. The parts of the first terminal 6.1 and the second terminal 6.2 extending into the transparent tube 6 do not contact each other, so that the two electric wires connected to the lower ends of the first terminal 6.1 and the second terminal 6.2 are in a disconnected state.

[0031] As shown in the drawings, Figure 3 and Figure 4As shown, the lower part of the transparent tube 6 is provided with a filter device 17. The filter device 17 has a sealed second outer shell 17.3. An oil inlet 17.1 is located on the upper side of the second outer shell 17.3, communicating with the interior of the second outer shell 17.3. A third outer shell 17.5 is coaxially located inside the second outer shell 17.3. Multiple circular holes are provided on the side of the third outer shell 17.5 for lubricating oil to pass through. A fourth outer shell 17.6 is coaxially located inside the third outer shell 17.5, also having multiple circular holes on its side for lubricating oil to pass through. The lower ends of the third outer shell 17.5 and the fourth outer shell 17.6 are sealed together, and filter paper 17.4 is installed between them. An oil outlet 17.2 is located at the top center of the filter device 17, communicating with the interior of the fourth outer shell 17.1. The oil inlet 17.1 is connected to the second adapter assembly 10 at the lower end of the reducer 1 via a second oil pipe 8, allowing lubricating oil in the reducer 1 to flow into the filter device 17 for filtration via the second oil pipe 8. The oil outlet 17.2 at the top of the filter device 17 is connected to the two-position three-way valve 19 via the fifth oil pipe 18, so that the filtered lubricating oil in the filter device 17 can be re-drawn into the reducer 1 for recycling.

[0032] like Figure 3 As shown, an oil sump 14 is installed on the right side inside the first housing 5. The bottom of the oil sump 14 is connected to a two-position three-way valve 19 via a fourth oil pipe 16. When there is no lubricating oil or the lubricating oil content inside the reducer 1 is low, new lubricating oil can be added into the reducer 1 through the oil sump 14. An oil pump 22 is installed in the middle position inside the first housing 5. The oil pump 22 is locked onto the first mounting bracket 11.2 with screws. The oil pump 22 is electrically connected to the electrical box 15, and the electrical box 15 can automatically control the start and stop of the oil pump 22.

[0033] The upper end of the oil pump 22 is connected to the first adapter assembly 2 at the upper end of the reducer 1 via the first oil pipe 3. The lower end of the oil pump 22 is connected to the two-position three-way valve 19 via the sixth oil pipe 21. The left side of the bottom of the two-position three-way valve 19 is connected to the filter device 17 via the fifth oil pipe 18, and the right side of the bottom of the two-position three-way valve 19 is connected to the oil sump 14 via the fourth oil pipe 16. Thus, the two-position three-way valve 19 can be used to control the selection of lubricating oil in the filter device 17 or the lubricating oil in the oil sump 14; the two-position three-way valve 19 is electrically connected to the electrical box 15, and the electrical box 15 can automatically control the connection position inside the two-position three-way valve 19.

[0034] An electrical box 15 is installed on the bottom side inside the first outer casing 5. The electrical box 15 contains an integrated control circuit that can automatically control the working state of the lubrication system. Two wires on the left side of the electrical box 15 are connected to the lower ends of the first terminal 6.1 and the second terminal 6.2 in the transparent tube 6, respectively. A power cord 7 is provided on the outside of the electrical box 15, allowing it to be connected to an external power source for operation, thus enabling the lubrication system of the textile machinery reducer to operate.

[0035] like Figure 5 As shown, the oil tank 14 contains a piston 13, which has a hollow internal pipe and an oil nozzle 12 at its top. The oil nozzle 12 is a one-way injection cup, allowing lubricating oil to be injected into the oil tank 14 from the outside through the top, while preventing oil in the oil tank 14 from overflowing back through the oil nozzle 12. The bottom of the piston 13 has a circular float 13.1. Lubricating oil flows into the oil tank 14 through the hollow internal pipe of the piston 13, lifting the float 13.1 and causing the entire piston 13 to float upwards. The piston 13 has graduations on its exterior, indicating the amount of lubricating oil in the oil tank 14. The float 13.1 is surrounded by sealing rings 13.2 to prevent lubricating oil leakage. The bottom of the oil tank 14 has a fourth oil pipe 16, which can be pumped by the oil pump 22 via a two-position three-way valve 19 and a sixth oil pipe 21.

[0036] like Figure 6 As shown, the first adapter 23 in the first adapter assembly 2 has an external thread at its bottom, which is tightened onto the eye bolt hole at the top of the reducer 1. The top of the first adapter 23 is sealed by inserting a first sealing plate 24. The first sealing plate 24 has a circular stepped surface in the middle, allowing it to fit tightly against the top of the first adapter 23.

[0037] The first sealing plate 24 has a dedicated hole connected to the first oil pipe 3 and the vent pipe 4. The first oil pipe 3 is connected to the oil pump 22, allowing the lubricating oil drawn by the oil pump 22 to enter the reducer 1 through the first adapter assembly 2. The vent pipe 4 is connected to the top of the transparent pipe 6, ensuring that the air pressure inside the reducer 1 is consistent with the air pressure inside the transparent pipe 6. The first sealing plate 24 is equipped with a one-way air valve 26, which ensures that the air pressure inside the reducer 1 is consistent with atmospheric pressure, thus preventing the lubricating oil from flowing out through the gaps of the bearings of the reducer 1 due to increased pressure when adding lubricating oil. The one-way air valve 26 also prevents external dust or other foreign objects from entering the reducer 1, causing lubricating oil contamination or abnormal operation of the reducer 1.

[0038] The first adapter 23 is provided with external threads on the top and is tightened by the first compression nut 25. The first compression nut 25 is compressed on the stepped surface of the first sealing plate 24, so that the first sealing plate 24 and the first adapter 23 can be completely sealed. The first adapter 23 and the first compression nut 25 are both hexagonal on the outside, which facilitates tightening with a hex wrench during installation.

[0039] The first oil pipe 3 at the first adapter assembly 2 extends into the pipeline inside the speed reducer 1 for a longer distance, and the breather pipe 4 extends into the pipeline inside the speed reducer 1 for a shorter distance, so as to prevent the air pressure near the inside of the connection part between the speed reducer 1 and the first adapter assembly 2 from being disturbed by the flow of lubricating oil flowing from the first oil pipe 3 into the speed reducer 1, thereby causing the air pressure inside the breather pipe 4 to be unstable, the air pressure and the lubricating oil level inside the transparent tube 6 to be unstable, and the hollow steel ball 20 floating on the surface of the lubricating oil inside the transparent tube 6 to move up and down constantly, so that the lubricating oil content inside the speed reducer 1 cannot be accurately observed.

[0040] As shown in Figure 7 The second adapter 29 in the second adapter assembly 10 is provided with external threads on the bottom, and is screwed into the oil outlet at the bottom of the speed reducer 1 through the external threads on the bottom of the second adapter 29. The top of the second adapter 29 is sealed by inserting the second sealing plate 27. The second sealing plate 27 is provided with a circular stepped surface in the middle part, so that the second sealing plate 27 can be tightly fitted on the top of the second adapter 29.

[0041] The second sealing plate 27 is provided with a special hole for connecting the second oil pipe 8 and the third oil pipe 9, wherein the second oil pipe 8 is connected to the filtering device 17, so that the lubricating oil inside the speed reducer 1 can enter the filtering device 17 through the second adapter assembly 10 for filtering. The third oil pipe 9 is connected to the bottom of the transparent tube 6, so that the speed reducer 1 and the transparent tube 6 are in fluid communication, and thus the lubricating oil level inside the speed reducer 1 can be determined by observing the lubricating oil level inside the transparent tube 6.

[0042] The second adapter 29 is provided with external threads on the top and is tightened by the second compression nut 28. The second compression nut 28 is compressed on the stepped surface of the second sealing plate 27, so that the second sealing plate 27 and the second adapter 29 can be completely sealed. The second adapter 29 and the second compression nut 28 are both hexagonal on the outside, which facilitates tightening with a hex wrench during installation.

[0043] The third oil pipe 9 extends into the inside of the speed reducer 1 with a longer pipe and at a higher position than the second oil pipe 8 which extends into the inside of the speed reducer 1 with a shorter pipe and at a lower position than the third oil pipe 9, so as to prevent the lubricating oil flow near the speed reducer 1 and the third oil pipe 9 extending into the inside of the speed reducer 1 from being disturbed by the lubricating oil flow from the inside of the speed reducer 1 into the second oil pipe 8, forming a turbulent flow phenomenon, thereby affecting the liquid level inside the transparent tube 6 connected with the third oil pipe 9, making the lubricating oil liquid level inside the transparent tube 6 unstable, so that the hollow steel ball 20 floating on the surface of the lubricating oil in the transparent tube 6 cannot be accurately observed to observe the lubricating oil content inside the speed reducer 1.

[0044] Example one: there is no lubricating oil inside the speed reducer 1. At this time, the hollow steel ball 20 in the transparent tube 6 is at the bottom of the transparent tube and contacts the first terminal 6.1 and the second terminal 6.2 at the bottom of the transparent tube 6, so at this time the first terminal 6.1 and the second terminal 6.2 are in a state of mutual connection. At this time, the electrical box 15 will control the two-position three-way valve 19 to connect the fourth oil pipe 16 and the sixth oil pipe 21, and control the oil pump 22 to suck the lubricating oil in the oil pool 14, flow into the inside of the speed reducer 1 through the first oil pipe 3, for the speed reducer 1 to work.

[0045] Example two: the lubricating oil inside the speed reducer 1 after working, through the second oil pipe 8 at the bottom of the speed reducer, flows into the filtering device 17 to circulate and filter iron filings and other impurities.

[0046] Example three: the lubricating oil inside the speed reducer 1 flows into the inside of the transparent tube 6 through the fourth oil pipe. At this time, the hollow steel ball 20 inside the transparent tube 6 is in a state of being lifted, representing that the lubricating oil content inside the speed reducer 1 is sufficient for the speed reducer 1 to work, so there is no need to add new lubricating oil into the inside of the speed reducer 1. Because the lubricating oil cannot conduct electricity, the first terminal 6.1 and the second terminal 6.2 at the bottom of the transparent tube 6 are in a state of mutual disconnection. At this time, the electrical box 15 will control the two-position three-way valve 19 to disconnect the fourth oil pipe 16 and the sixth oil pipe 21 from each other, and connect the fifth oil pipe 18 and the sixth oil pipe 21 with each other. At this time, the oil pump 22 will re-suck the clean lubricating oil filtered in the filtering device 17, flow into the inside of the speed reducer 1 through the first oil pipe 3, for the speed reducer 1 to work.

[0047] Example four: the lubricating oil inside the reducer 1 is constantly consumed, or leaks through the bearing gap of the reducer 1, at this time the lubricating oil level inside the reducer 1 drops, so that the lubricating oil level inside the transparent tube 6 also drops. When the hollow steel ball 20 inside the transparent tube 6 constantly drops to contact the first terminal 6.1 and the second terminal 6.2 at the bottom of the transparent tube 6, at this time the first terminal 6.1 and the second terminal 6.2 are in a state of mutual connection. At this time the electrical box 15 will control the two-position three-way valve 19 to disconnect the fifth oil pipe 18 and the sixth oil pipe 21 from each other, and connect the fourth oil pipe 16 and the sixth oil pipe 21 to each other. At this time the oil pump will suck the lubricating oil in the oil pool 14, flow into the inside of the reducer 1 through the first oil pipe 3, and supplement the lubricating oil inside the reducer 1.

[0048] Example five: the lubricating oil inside the reducer 1 is constantly supplemented by the oil pool 14, so that the liquid level inside the reducer 1 constantly rises, so that the hollow steel ball 20 inside the transparent tube 6 is raised again. At this time the first terminal 6.1 and the second terminal 6.2 at the bottom of the transparent tube 6 return to a state of mutual disconnection, at this time the electrical box 15 will control the two-position three-way valve 19 to disconnect the fourth oil pipe 16 and the sixth oil pipe 21 from each other, and connect the fifth oil pipe 18 and the sixth oil pipe 21 to each other. At this time the oil pump 22 will re-suck the filtered clean lubricating oil in the filtering device 17, flow into the inside of the reducer 1 through the first oil pipe 3, and be used for the circulating work of the reducer 1.
