Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for lubrication systems of rotary reducers, and in particular to a lubricating oil filtration and return device for rotary reducers. Background Technology
[0002] As a core transmission component in fields such as engineering machinery and mining equipment, the normal operation of precision parts such as gears and bearings in rotary reducers is highly dependent on the lubrication and cooling of lubricating oil. During long-term use, lubricating oil is prone to mixing with impurities such as metal shavings, dust, and wear particles. If it is not purified in time, it will lead to a decrease in lubrication effect, aggravate the wear of parts, shorten the service life of the reducer, and even cause serious failures such as seizure and shaft breakage. Existing lubricating oil filtration and return devices generally have separate filtration and return structures, resulting in a large overall size. This makes them less flexible when adapting to small or space-constrained rotary reducers. In addition, the return path design is simple, resulting in low lubricating oil return efficiency after filtration. Furthermore, the lack of a backup flow path means that lubrication can be interrupted if the main filter component becomes clogged. Therefore, this utility model proposes a lubricating oil filtration and return device for a rotary reducer. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lubricating oil filtration and return device for rotary reducers.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rotary reducer lubricating oil filtration and return device, comprising a filtration assembly, the filtration assembly being composed of a main frame and a filtration mechanism, and further comprising a fixed bracket provided above the filtration mechanism on the main frame; The reflux assembly consists of a three-way pipe that is snapped onto the filter mechanism. The vertical end of the three-way pipe has two flow-diverting chambers. One horizontal end of the three-way pipe is fixedly connected to a first connecting pipe, and the other horizontal end of the three-way pipe is fixedly connected to a second connecting pipe.
[0005] Furthermore, the other end of the first connecting pipe is fixedly connected to the output end of the filter mechanism, and the other end of the second connecting pipe is fixedly connected to the input end of the filter mechanism.
[0006] The beneficial effects of adopting the above-mentioned further solution are: the first connecting pipe connects to the output end of the filter mechanism and the second connecting pipe connects to its input end, allowing the lubricating oil to flow through the filter mechanism along a fixed path, avoiding the flow channel chaos that would cause unfiltered oil to mix with clean oil, thus ensuring the filtration effect; at the same time, this corresponding connection method makes the components tightly connected, reducing the risk of oil leakage, and also makes the oil flow smoother, helping the device to operate stably, and also providing convenience for quick positioning of pipelines during subsequent maintenance.
[0007] Furthermore, a connector assembly is provided at the top of the tee pipe, the connector assembly being composed of a straight pipe fixedly connected to the top of the tee pipe.
[0008] The beneficial effects of adopting the above-mentioned further solution are as follows: The top of the tee pipe is equipped with a connector assembly, and its straight pipe is fixedly connected to the tee pipe, making the oil flow channel more compact and continuous, avoiding pipeline mess. This structure allows the oil to flow in an orderly manner, reducing flow resistance, and also makes the overall layout of the device more regular and saves installation space. At the same time, the fixed connection between the two enhances the connection stability, reduces the possibility of oil leakage, and allows for quick identification of the flow path during subsequent inspection or maintenance, making operation more convenient.
[0009] Furthermore, the straight pipe has two cavities formed inside by a partition, and the two cavities are respectively connected to the first connecting pipe and the second connecting pipe.
[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the straight pipe is divided into two chambers by a partition, and the chambers are respectively connected to the first connecting pipe and the second connecting pipe. This allows the oil to flow independently in their respective chambers, avoiding the mixing of unfiltered and filtered oil, ensuring the cleanliness of the filtered oil. The partition structure also makes the flow path clearer, preventing the oil from flowing in a chaotic or stagnant manner, thus improving the overall flow efficiency. At the same time, the independent chambers also reduce mutual interference between oils in different paths, enhancing the operational stability of the device, and making it easier to troubleshoot flow path problems during subsequent maintenance.
[0011] Furthermore, filter elements are embedded in both sides of the partition inside the straight pipe, and the filter elements have a semi-circular structure.
[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: The semi-circular filter elements embedded on both sides of the baffle inside the straight pipe can filter the oil in the two chambers separately, so that both the unfiltered and filtered oil are purified, improving the overall filtration effect. The semi-circular design fits the inner wall of the straight pipe, making full use of the space and avoiding filtration dead corners. The embedded installation makes the filter element stable and does not shake, and it is also convenient to disassemble and replace. It not only ensures continuous and effective filtration, but also makes maintenance easier and reduces the resistance when the oil flows, making the device operate more smoothly.
[0013] Furthermore, a top cover is fixedly connected to the top of the straight pipe, and an inlet pipe and an outlet pipe are fixedly connected to the top of the top cover in sequence. The inlet pipe is connected to the second connecting pipe, and the outlet pipe is connected to the first connecting pipe.
[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the top of the straight pipe is fixedly connected to the top cover, which in turn is connected to the inlet pipe and the outlet pipe in sequence, and is also connected to the second connecting pipe and the first connecting pipe respectively, so that the oil can enter and exit in an orderly manner along a fixed path. The top cover can not only seal the inside of the straight pipe to prevent oil leakage or the entry of external impurities, but also avoid the pipeline from being messy through the regular pipe opening layout. This structure makes the oil flow smoother and will not cause the path to be chaotic. When it is necessary to inspect or maintain it later, the oil inlet and outlet path can be quickly identified, making the operation more convenient, while also ensuring the overall stability of the device operation.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the three-way pipe of the reflux assembly is snapped onto the filter mechanism. The two diversion chambers at the vertical end, together with the two connecting pipes at the horizontal end, allow the oil to flow along a fixed path, avoiding mixing and affecting the filtration effect. The snap-fit method makes installation and disassembly more convenient, and facilitates quick disassembly of components during maintenance. The design of the diversion chambers makes the oil flow more orderly and reduces mutual interference. The connecting pipes securely connect to the filter mechanism, ensuring smooth oil delivery and improving the overall reliability of the device operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a rotary reducer lubricating oil filtration and return device, including a filter assembly 1, which is composed of a main frame 11 and a filter mechanism 13, and also includes a fixed bracket 12 provided above the filter mechanism 13 on the main frame 11. The return flow assembly 2 consists of a three-way pipe 21 that is snapped onto the filter mechanism 13. The vertical end of the three-way pipe 21 has two diversion chambers 24. One horizontal end of the three-way pipe 21 is fixedly connected to a first connecting pipe 22, and the other horizontal end of the three-way pipe 21 is fixedly connected to a second connecting pipe 23. By snapping the three-way pipe 21 onto the filter mechanism 13, the two diversion chambers 24 at the vertical end, together with the two connecting pipes at the horizontal end, allow the oil to flow along a fixed path, avoiding mixing and affecting the filtration effect. The snap-fit method makes installation and disassembly more convenient, and facilitates quick disassembly of components during maintenance. The design of the diversion chambers 24 makes the oil flow more orderly and reduces mutual interference. The connecting pipes are firmly connected to the filter mechanism 13, ensuring smooth oil delivery and improving the overall reliability of the device operation.
[0021] The other end of the first connecting pipe 22 is fixedly connected to the output end of the filter mechanism 13, and the other end of the second connecting pipe 23 is fixedly connected to the input end of the filter mechanism 13. The first connecting pipe 22 is connected to the output end of the filter mechanism 13, and the second connecting pipe 23 is connected to the input end, so that the lubricating oil can flow through the filter mechanism 13 along a fixed path, avoiding the flow channel chaos that causes unfiltered oil to mix with clean oil, and ensuring the filtration effect. At the same time, this corresponding connection method makes the components tightly connected, reduces the risk of oil leakage, and makes the oil flow smoother, which helps the device to operate stably and also provides convenience for quick positioning of pipelines during subsequent maintenance.
[0022] The top of the tee pipe 21 is equipped with a connector assembly 3, which consists of a straight pipe 31 fixedly connected to the top of the tee pipe 21. The connector assembly 3 is fixedly connected to the tee pipe 21, making the oil flow channel more compact and continuous, avoiding pipeline clutter. This structure allows the oil to flow in an orderly manner, reducing flow resistance and making the overall layout of the device more regular and saving installation space. At the same time, the fixed connection between the two enhances the connection stability, reduces the possibility of oil leakage, and allows for quick identification of the flow path during subsequent inspection or maintenance, making operation more convenient.
[0023] Two cavities are formed inside the straight pipe 31 by a partition 35. The two cavities are connected to the first connecting pipe 22 and the second connecting pipe 23, respectively. The partition 35 divides the straight pipe 31 into two cavities, which are connected to the first connecting pipe 22 and the second connecting pipe 23, respectively. This allows the oil to flow independently in their respective cavities, avoiding the mixing of unfiltered and filtered oil, ensuring the cleanliness of the filtered oil. The separation structure makes the flow path clearer, and the oil flow will not be chaotic or stagnant, improving the overall flow efficiency. At the same time, the independent cavities also reduce mutual interference between oils in different paths, enhance the stability of the device operation, and make it easier to troubleshoot flow path problems during subsequent maintenance.
[0024] Filter elements 36 are embedded on both sides of the partition 35 inside the straight pipe 31. The filter elements 36 have a semi-circular structure. The semi-circular filter elements 36 embedded on both sides of the partition 35 inside the straight pipe 31 can filter the oil in the two chambers separately, so that both unfiltered and filtered oil are purified, improving the overall filtration effect. The semi-circular design fits the inner wall of the straight pipe 31, making full use of space and avoiding filtration dead corners. The embedded installation makes the filter elements 36 stable and does not shake, and it is also easy to disassemble and replace. It not only ensures continuous and effective filtration, but also makes maintenance easier and reduces the resistance when the oil flows, making the device operate more smoothly.
[0025] The top of the straight pipe 31 is fixedly connected to the top cover 32. The top of the top cover 32 is sequentially connected to the inlet pipe 33 and the outlet pipe 34. The inlet pipe 33 is connected to the second connecting pipe 23, and the outlet pipe 34 is connected to the first connecting pipe 22. The top of the straight pipe 31 is fixedly connected to the top cover 32, which is in turn connected to the inlet pipe 33 and the outlet pipe 34 in sequence. It is also connected to the second connecting pipe 23 and the first connecting pipe 22 respectively, so that the oil can enter and exit in an orderly manner along a fixed path. The top cover 32 can seal the inside of the straight pipe 31 to prevent oil leakage or the entry of external impurities. It can also avoid the pipeline from being messy through the regular pipe opening layout. This structure makes the oil flow smoother and will not cause the path to be messy. When it is necessary to inspect or maintain it later, the oil inlet and outlet path can be quickly identified, making the operation more convenient. At the same time, it can also ensure the overall stability of the device operation.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
