Description

Technical Field

[0001] The present invention relates to the technical field of speed reducers, and in particular to a dynamic lubrication type cycloid speed reducer and a method for using the same. Background Art

[0002] Although traditional cycloid reducers have advantages such as high reduction ratios and compact structures in the field of industrial transmission, they still face many technical bottlenecks in practical applications. The problem of increased gear wear due to insufficient lubrication is particularly prominent. Traditional grease lubrication or static oil bath lubrication methods are difficult to form an effective oil film in the gear meshing area. Especially under high-speed and heavy-load conditions, the accumulation of metal debris will accelerate the deterioration of the oil. Insufficient heat dissipation performance is also a significant defect. The heat generated by gear friction cannot be dissipated in time, resulting in a significant temperature rise in the reducer. This not only reduces the viscosity of the lubricating oil, but may also cause aging of seals and gear bonding failure. High maintenance costs also plague users. Due to the lack of an effective filtration system, the oil is severely contaminated and the lubricating oil needs to be replaced frequently, which not only increases costs but also affects production efficiency.

[0003] In addition, traditional structures are prone to transmission shock during startup and speed changes, affecting the smoothness of movement and potentially leading to a decrease in positioning accuracy in precision transmission situations. Existing improvement solutions, such as optimizing gear parameters or forced lubrication, often present new problems such as complex systems, high energy consumption, or inconvenient maintenance. These technical shortcomings have severely restricted the application of cycloid reducers in the field of high-end equipment manufacturing. There is an urgent need for an innovative solution that can achieve dynamic lubrication, efficient heat dissipation, low wear, and easy maintenance to break through existing technical bottlenecks. Therefore, a dynamically lubricated cycloid reducer and its use method are now needed. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The present invention provides: a dynamic lubrication cycloid reducer, such as Figures 1-8 As shown, it includes a base 1, a support base 2 is fixedly installed in the middle of the upper surface of the base 1, a protective cover 4 is provided on the upper part of the support base 2, a reduction gear module 5 is provided inside the protective cover 4, a filter component is installed on the upper surface of the base 1 at one end of the protective cover 4, and an oil pump component is installed on the upper surface of the base 1 at the other end of the protective cover 4. The cooperation of the filter component and the oil pump component is used to complete the circulation of the liquid lubricating oil inside the protective cover 4, thereby better ensuring the stability of the reduction gear module 5 inside the protective cover 4 during the rotation deceleration process, reducing friction, and improving the service life of the reduction gear module 5; The filter assembly and the oil pump assembly are both installed in communication with the protective sleeve 4. By connecting the filter assembly and the oil pump assembly with the protective sleeve 4, the lubricating oil inside the protective sleeve 4 can circulate and filter the lubricating oil, thereby better ensuring that the reduction gear module 5 rotating inside the protective sleeve 4 can work stably and continuously, and preventing the reduction gear module 5 from excessive wear during use; The filter assembly includes a filter box 25 mounted on the upper surface of the base 1. Two groups of liquid separators 26 are symmetrically mounted on the inner wall of the filter box 25. A liquid separator block 29 is mounted in the middle of the filter box 25, and a group of filter cotton 30 is mounted on the front and rear sides of the liquid separator block 29. Two groups of liquid plates 31 are embedded on the upper surface of each group of filter cotton 30. The filter box 25 is provided to filter the lubricating oil discharged from the inside of the protective cover 4. At the same time, the state of circulation, discharge and replenishment of the lubricating oil can be changed by selecting the use of the liquid outlet pipes 28 on both sides. The liquid separator 26 is provided to limit the lubricating oil to only be filtered and seeped through the filter cotton 30 and enter the circulation state, thereby improving the service life of the lubricating oil. The oil pump assembly includes an oil tank 35, and a liquid baffle 38 is sealed and inserted inside the oil tank 35, and a group of liquid outlet plates 39 are installed on both sides of the liquid baffle 38. The liquid baffle 38 and the liquid outlet plate 39 are separated from the oil tank 35 and filled with porous filter material 40. The oil tank 35 is connected to the filter box 25 so that the lubricating oil can circulate. In addition, the liquid baffle 38 and the liquid outlet plate 39 are used together to limit the flow state of the lubricating oil, so that the lubricating oil must flow through the porous filter material 40 to the inside of the liquid outlet plate 39, thereby completing the circulation of the lubricating oil.

[0020] Preferably, the reduction gear module 5 includes a limiting roller 6, and the outer arc surface of the limiting roller 6 is sleeved with a sealing sleeve 7, which is sealed and connected to the opening of one end of the protective sleeve 4, and a bearing 8 is rotatably installed on one side of the sealing sleeve 7. The limiting roller 6 is located at one end inside the protective sleeve 4 and is provided with a reduction socket 9. The outer arc surface of the limiting roller 6 is sleeved with a first positioning seat 10, and two groups of first cycloidal wheels 11 are installed on one side of the first positioning seat 10. A turntable is rotatably installed inside the two groups of first cycloidal wheels 11, and several groups of first needle wheels 12 cooperating with the first cycloidal wheels 11 are respectively installed on both sides of the turntable. The sealing sleeve 7 and bearing 8 arranged on the surface of the limiting roller 6 ensure the overall rotation smoothness of the reduction gear module 5. The set first positioning seat 10 and the first cycloidal wheel 11 achieve the purpose of buffering and deceleration through continuous rotation, and reduce friction loss through the continuous rotation reduction working mode, improve system efficiency, reduce temperature rise, and the recycled lubricating oil can also play a role in lubricating the cycloidal wheel.

[0021] Furthermore, the reduction gear module 5 also includes a connecting rod 17 installed with the limit roller 6, and a plurality of plug-in plates 18 are installed on the outer arc surface of the connecting rod 17. Two sets of second cycloid wheels 15 are sleeved on the outer arc surface of the connecting rod 17, and another set of turntables are rotatably installed between the two sets of second cycloid wheels 15, and a plurality of second pin wheels 16 used in conjunction with the second cycloid wheels 15 are respectively installed on both sides of the other set of turntables. The plug-in plates 18 installed on the outer arc surface of the connecting rod 17 cooperate with the reduction socket 9 opened at one end of the limit roller 6, so that the limit roller 6 will not directly drive the connecting rod 17 to rotate during the rotation process. After the limiting roller 6 rotates, the deceleration socket 9 contacts the plug plate 18 and the plug plate 18 is subjected to force, thereby completing the driving of the connecting rod 17, so that the rotation of the connecting rod 17 has a buffering effect. In addition, the second cycloid wheel 15 and the second needle wheel 16 installed on the outer arc surface of the connecting rod 17 have different initial rotation speeds, which makes the second cycloid wheel 15, the second needle wheel 16 and the first cycloid wheel 11, the first needle wheel 12 have different deceleration states, so that the overall deceleration effect of the reduction gear module 5 is improved. After the speed is synchronized, the synchronized limiting roller 6 and the connecting rod 17 can be better used in combination due to the multi-round deceleration.

[0022] Furthermore, a locking sleeve 13 is installed at the connection between the limiting roller 6 and the connecting rod 17, and a second positioning seat 14 is installed on one side of the locking sleeve 13. One side of the second positioning seat 14 is pressed against the surface of the second cycloid wheel 15. The outer arc surface of the connecting rod 17 is installed with a head 19 used in conjunction with the protective sleeve 4. A speed reduction disc 20 is fixedly installed on the outer end of the connecting rod 17. The limiting roller 6 and the connecting rod 17 are connected by the set locking sleeve 13, but the connection of the locking sleeve 13 only ensures the connection state of the limiting roller 6 and the connecting rod 17, and does not prevent the independent rotation of the limiting roller 6 and the connecting rod 17. The set second positioning seat 14 presses against the surface of a group of second cycloid wheels 15 to limit the two groups of second cycloid wheels 15.

[0023] It is worth mentioning that a positioning ring 21 is embedded and installed between the corresponding bearing 8 and the first positioning seat 10 inside the protective sleeve 4, and several groups of first reduction wheels 22 are rotatably installed inside the protective sleeve 4 corresponding to the two groups of first cycloidal wheels 11. Several groups of second reduction wheels 23 are rotatably installed inside the protective sleeve 4 corresponding to the two groups of second cycloidal wheels 15. The positioning ring 21 limits the limiting roller 6 to ensure the stability of the overall use of the reduction gear module 5, and the first reduction wheels 22 and the second reduction wheels 23 are both located in cooperation with the reduction gear module 5 to perform deceleration work and improve the deceleration efficiency.

[0024] Specifically, two groups of filter plates 27 are respectively installed on the upper parts of the front and rear sides of each group of liquid separators 26, and two groups of liquid outlet pipes 28 are installed on the left and right sides of the filter box 25 corresponding to the installation positions of the liquid separator box 26. An inclined angle is set on both sides of the liquid separator block 29, and the two groups of liquid plates 31 inserted and installed on the upper part of the filter cotton 30 are respectively arranged corresponding to the liquid separator box 26, and the liquid separator plate 31 does not completely penetrate the filter cotton 30. The liquid separator block 29 can make the lubricating fluid entering the filter box 25 be diverted to the upper parts of the two groups of filter cotton 30. Through the installation of the liquid separator plate 31, the lubricating oil on the surface of the filter cotton 30 will seep out through the bottom of the liquid separator plate 31 and be diverted and accumulated through the restriction of the liquid separator plate 31, so that the two sides of the two groups of liquid plates 31 are the filtered lubricating oil, and the lubricating oil to be filtered is between the two groups of liquid plates 31, so as to improve the filtering effect, so that the filtered lubricating oil can flow through the filter plates 27 opened on both sides of the liquid separator box 26 and complete the discharge work through the liquid outlet pipe 28.

[0025] In addition, the upper part of the filter box 25 is sealed with a first cover plate 32, and a first connecting pipe 33 is installed through the center of the first cover plate 32. The outer arc surface of the protective cover 4 is sealed with an electric control valve 24 corresponding to the position of the first connecting pipe 33. The first connecting pipe 33 is sealed and connected to the electric control valve 24. The bottom of the first connecting pipe 33 is installed in the center of the liquid separator 29. The first connecting pipe 33 installed in the center of the first cover plate 32 is connected and installed with the electric control valve 24. The circulation state of the lubricating oil is controlled by opening the electric control valve 24, which can well clean the filter cotton 30 inside the filter box 25 to improve the service life of the device.

[0026] It is worth noting that a conversion box 3 is fitted on the left side of the support seat 2, and a sealing cover on the outer side of the conversion box 3 is provided with a sealing plate 34. The oil tank 35 is fixedly connected to the sealing plate 34, and a second connecting pipe 36 is installed on the right side of the oil tank 35. The liquid outlet pipe 28 on the left side of the filter box 25 passes through the conversion box 3 and is connected to the second connecting pipe 36. The conversion box 3 is provided to protect the oil tank 35 to prevent the external environment from polluting the lubricating oil inside the oil tank 35. The water pump 42 can also be protected by the conversion box 3 and the sealing plate 34, so that the use state of the lubricating oil is more stable. The water pump provided in this embodiment is a speed-controlled water pump. The motor speed is adjusted by the frequency converter to change the flow and head of the water pump 42 to avoid energy waste caused by valve throttling. At the same time, the water pump 42 is connected with a contactor, a circuit breaker, and a thermal relay protection, which can well control the output state problem of the water pump, thereby ensuring the circulation of the lubricating oil.

[0027] Preferably, the bottom of the liquid baffle 38 does not contact the lower surface of the interior of the oil bin 35, and the bottom of the liquid outlet plate 39 is fixedly in contact with the lower surface of the interior of the oil bin 35. The top end of the oil bin 35 is covered with a second cover plate 41, and a water pump 42 is bolted to the upper surface of the second cover plate 41. The input end of the water pump 42 passes through the second cover plate 41 and extends into the interior of the filter sleeve 37. The output end of the water pump 42 passes through the protective sleeve 4 and is sealed. The liquid baffle 38 does not contact the lower surface of the interior of the oil bin 35, so that the lubricating oil can seep out through the bottom. The bottom oil body is prevented from directly flowing out by the liquid outlet plate 39. The porous filter material 40 is provided to complete further adsorption treatment of the lubricating oil, ensure the stable use of the lubricating oil, and make the lubricating oil flow to the inside of the liquid outlet plate 39. The filter plate 27 is provided to further protect the input end of the water pump 42, thereby further improving the filtering effect.

[0028] A method for using a dynamic lubrication cycloid reducer comprises the following steps: S1. Refueling and waiting for startup: The device fills the oil tank 35 with liquid lubricating oil for lubrication, covers the top of the oil tank 35 with the second cover plate 41, and then connects the water pump 42 and the protective cover 4 to ensure that there is enough lubricating oil in the oil tank 35 to smoothly operate the reduction gear module 5 inside the reducer. The device first fills the protective cover 4 and the oil tank 35 with liquid to ensure lubrication during the rotation of the reduction gear module 5. In addition, when the reduction gear module 5 is working, the activation of the water pump 42 causes the lubricating oil stored in the oil tank 35 to be sent into the protective cover 4. The internal space of the protective cover 4 is fixed, so that the lubricating oil in the protective cover 4 is squeezed into the filter box 25 for filtration; S2. Oil replenishment assistance: During the rotation of the reduction gear module 5, the water pump 42 slowly draws the liquid lubricating oil in the oil tank 35 into the protective sleeve 4 to ensure the flow of liquid lubricating oil in the protective sleeve 4. In addition, new lubricating oil is injected into the liquid outlet pipe 28 on the right side of the filter box 25 to ensure that there is no vacuum period of filtration in the entire device. After the liquid lubricating oil is drawn into the protective sleeve 4 through the oil tank 35, the excess lubricating oil is squeezed into the filter box 25 to complete the filtration, thereby maintaining the circulation of the lubricating oil in the protective sleeve 4. During the circulation of the lubricating oil, the lubrication state of the entire device can be improved by replenishing the lubricating oil in the filter box 25. The filter cotton 30 and the liquid separator 31 provided in the filter box 25 can cooperate to filter the lubricating oil to avoid the working wear of the reduction gear module 5 caused by impurities carried by the lubricating oil. S3. Return oil and replace with new oil: After the device has been used for a period of time, the solenoid valve in the middle of the liquid outlet pipe 28 is operated to discharge the lubricating oil after circulation. After the discharge is completed, new lubricating oil is added to the inside of the filter box 25 to continue lubricating the reduction gear module 5 inside the protective cover 4, so as to ensure the safety of the overall use of the reduction gear module 5 and reduce friction loss. When the reduction gear module 5 works for a long time, replacing the lubricating oil can well ensure the rotation stability of the reduction gear module 5 and improve the safety of the use of the reduction gear module 5.
