[0002] In the modern industrial field, heavy-duty speed reducers are widely used in many industries such as metallurgy, mining, port machinery, and heavy machine tools, and are key equipment for realizing power transmission and speed conversion. During the operation of a heavy-duty speed reducer, it needs to withstand high loads, high torques, and complex and variable working conditions. As an important component of the heavy-duty speed reducer, the housing not only provides support and protection for internal transmission components such as gears and shafts, but also needs to have good sealing performance to ensure the normal operation of the speed reducer; The existing transmission devices cannot combine the sealing structure with the lubrication component, resulting in ineffective lubrication inside the sealing component near the speed reducer, and it is inconvenient to handle oil stains when disassembling the sealing component, thus making it difficult to ensure good sealing and leakage prevention effects and adapt to different working conditions. For this reason, we propose a heavy-duty speed reducer housing with an efficient sealing structure. Summary of the Invention

Detailed Embodiment

[0016] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation on the present invention.

[0017] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] In modern industrial drive systems, high requirements are put forward for the performance, reliability, and maintenance convenience of drive devices. There are obvious deficiencies in the combination of the sealing structure and the lubrication component in existing drive devices. On the one hand, the design of the sealing structure focuses on preventing medium leakage, but it is difficult to work in coordination with the lubrication component. For example, common seals such as O-ring seals and lip seals mainly function to prevent internal lubricating oil from leaking out and external impurities from entering. However, they have limitations in lubrication and cannot effectively guide the lubricating oil into the sealing component, resulting in increased wear of the sealing component due to insufficient lubrication and shortening the service life of the sealing component. On the other hand, the lubrication component is usually set independently, such as oil sump lubrication, oil mist lubrication, etc., and it is difficult to accurately provide continuous and stable lubrication for the sealing component. This separated design makes the lubricating oil unable to fully play its lubricating role, easily causing waste and leakage of the lubricating oil, increasing the maintenance cost of the equipment and the risk of environmental pollution. In addition, in practical applications, when it is necessary to disassemble the sealing component for maintenance, the existing structure makes it difficult to disassemble and clean the ink, further affecting the maintenance efficiency and operation stability of the equipment. A heavy-duty reducer box body with an efficient sealing structure according to the present invention, please refer to the attached Figure 1 - attached Figure 8, including a structural body 1, the structural body 1 includes a detachable component 6, a sealing component 5 connected to the detachable component 6, a lubricating component 9 connected to the sealing component 5, and a guiding component 8 connected to the lubricating component 9. The sealing component 5 includes a lip seal ring 51, a fitting ring 52, a first moving ring 53, a clamping groove 54, and a second moving ring 55. The fitting ring 52 is arranged on the lip seal ring 51, and a lubrication port 7 is provided on the fitting ring 52. The clamping groove 54 is arranged inside the first moving ring 53. The second moving ring 55 and the first moving ring 53 match each other. Through grooves 56 are provided on both the second moving ring 55 and the first moving ring 53. The fitting ring 52 penetrates through the two through grooves 56. When lubricating oil enters the interior of the lubrication port 7, the lubricating oil enters the interiors of the first moving ring 53 and the second moving ring 55 respectively from the interior of the fitting ring 52 to achieve lubrication. The guiding component 8 includes an oil retaining disc 81. An annular groove 82 is provided inside the oil retaining disc 81. A guiding ring 84 is arranged at the bottom of the oil retaining disc 81. An oil seepage port 83 is provided between the guiding ring 84 and the oil retaining disc 81. The interior of the guiding ring 84 is of a hollow structure. The cross-section of the guiding ring 84 is semi-circular, and a guiding protrusion is provided on the inner wall. Two communication ports 85 are arranged on the bottom surface of the guiding ring 84. The lubricating component 9 includes a collecting disc 91 and a conical plate 92. Oil-resistant rubber tubes 93 are arranged on the front and rear surfaces of the collecting disc 91. A micro pump 94 is arranged on the oil-resistant rubber tube 93. The conical plate 92 is arranged inside the collecting disc 91. By arranging the special shape of the conical plate 92, the lubricating oil is guided into both sides of the collecting disc 91. Through the oil-resistant rubber tubes 93, it is convenient to guide the lubricating oil to the sealing component 5 to lubricate the sealing component 5, thereby ensuring a good sealing effect and adapting to different working conditions.

[0019] Example 1: A base 2 is arranged at the bottom of the structural body 1. A sealing box body 3 is arranged on the base 2. Grooves are provided on both the front and rear surfaces of the sealing box body 3. The detachable component 6 includes a clamping plate 61, a sealing ring 62, a spring 63, and an inclined plate 64. The two clamping plates 61 are both arranged inside the grooves. The two sealing rings 62 are respectively arranged on the inner side and the outer side of the sealing box body 3. The two inclined plates 64 are respectively arranged on the left and right surfaces of the clamping plate 61 through the spring 63. Specifically, by arranging the two sealing rings 62 on both sides of the groove, it is convenient to achieve a sealing effect on the groove at the sealing box body 3. When the detachable component 6 needs to be removed, after removing the top plate, press the two inclined plates 64. The two inclined plates 64 are converted from an inclined state to a parallel state under the action of the spring 63, so as to facilitate the disassembly and separation of the sealing component 5 and the detachable component 6 from the sealing box body 3.

[0020] Example 2: A transmission device 4 is arranged inside the sealing box body 3. The transmission device 4 includes a driving bevel gear 41. Two driven bevel gears 42 are meshed with the driving bevel gear 41. Through holes are provided at the centers of the lip seal ring 51, the fitting ring 52, the first moving ring 53, and the second moving ring 55. Specifically, by setting the lip seal ring 51, it can effectively prevent the leakage of lubricating oil from the joint between the sealed housing 3 and the transmission device 4. Its lip fits tightly with the relative moving parts, can adapt to a certain degree of axial and radial displacement, and ensure the sealing effect. The holes are arranged in the internal centers of the lip seal ring 51, the fitting ring 52, the first moving ring 53 and the second moving ring 55, enabling the shaft to pass through smoothly without affecting the rotation effect of the shaft.

[0021] Specifically, the setting of the fitting ring 52 plays a role in positioning and auxiliary sealing. It cooperates with the lip seal ring 51 to enhance the sealing performance. The holes on the fitting ring 52 correspond to the holes of the lip seal ring 51 to ensure the installation accuracy and stability of the shaft. The first moving ring 53 and the second moving ring 55 achieve dynamic sealing. The holes inside the first moving ring 53 and the second moving ring 55 are also used for the installation of the shaft. When the shaft rotates, the first moving ring 53 and the second moving ring 55 can fit tightly to prevent the leakage of lubricating oil.

[0022] Specifically, the power transmission and direction change are achieved by setting the driving bevel gear 41 and two driven bevel gears 42. When the driving bevel gear 41 rotates, it drives the driven bevel gear 42 to rotate through the meshing of the tooth surfaces, providing power output for the entire transmission device 4. During the working process, it effectively reduces the friction and wear during gear meshing, and improves the transmission efficiency and reliability.

[0023] Embodiment 3: Heat dissipation grooves are provided on both the left and right sides of the base 2. An opening is provided at the bottom of the sealed housing 3, and the opening communicates with the base 2. A heat dissipation fan is provided inside the base 2. Fixed bottom plates are provided at the four corners of the base 2, and each fixed bottom plate is provided with a fastening bolt. A top plate is provided on the top of the sealed housing 3, and the top plate is set on the sealed housing 3 through screws. The lip seal ring 51 and the seal ring 62 are made of rubber. The numbers of the sealing assembly 5, the detachable assembly 6 and the lubricating assembly 9 are all set to two. The semi-circular design of the guiding ring 84 can reduce the flow resistance of the oil fluid, and the hollow structure is used to accommodate the reflux lubricating oil.

[0024] Specifically, a connecting plate is provided between the detachable assembly 6 and the sealing assembly 5. The sealing assembly 5 is connected to the lubricating assembly 9 through an oil-resistant rubber tube 93. The lubricating assembly 9 is connected to the guiding assembly 8 through the guiding ring 84. The lubricating oil enters the inside of the collecting tray 91 from inside the guiding ring 84, and the lubricating oil is guided into the inside of the sealing assembly 5 through the micro pump 94. When the lubricating oil enters the inside of the lubricating port 7, the lubricating oil enters the inside of the first moving ring 53 and the second moving ring 55 respectively from the inside of the fitting ring 52 to achieve lubrication; Specifically, the lubricating oil is collected by setting up the collecting tray 91. The design of the conical plate 92 facilitates the entry of the lubricating oil into the interiors of the two oil-resistant rubber hoses 93. The micro pump 94 is activated to guide the lubricating oil into the interior of the lubricating port 7, thereby guiding the lubricating oil into the interior of the lip seal ring 51 of the sealing assembly 5, achieving the combination of the lubricating assembly 9 and the sealing assembly 5, and facilitating the effective lubrication of the interior of the sealing assembly 5 near the speed reducer. Specifically, by detaching the oil-resistant rubber hose 93 from the lubricating port 7 and pressing the inclined plate 64, the spring 63 is compressed, causing the inclined plate 64 to change from an inclined state to a parallel state, thereby driving the detachable assembly 6 and the lip seal ring 51 to drive the fitting ring 52 to be detached from the driven ring one 53 and the moving ring two 55, achieving the effect of processing the ink while detaching the sealing assembly 5, and further ensuring a good sealing and anti-leakage effect and adapting to different working conditions. The spring 63 is fixed between the engaging plate 61 and the inclined plate 64, and the inclined plate 64 can slide along the groove. Specifically, through the cooperation of the lip seal ring 51, the moving ring one 53, and the moving ring two 55 in the sealing assembly 5, a multiple sealing effect is achieved to prevent the leakage of the lubricating oil. And with the setting of the lubricating assembly 9, while achieving sealing, the sealing assembly 5 is lubricated. The lubricating oil finally enters the interior of the oil baffle 81 through the sealing assembly 5 and re-enters the interior of the collecting tray 91 for collection. This not only reduces the frictional resistance but also takes away the heat generated by friction, avoiding the waste of the lubricating oil while ensuring a good lubrication effect.

[0025] Working principle: First, install the dynamic ring 1 53 and the dynamic ring 2 55 in the sealing assembly 5 to the lip sealing ring 51 through the through groove 56, and at the same time press the inclined plate 64 to the inside of the sealing box 3 to change from a parallel state to an inclined state, and finally achieve the sealing effect synchronously through the two sealing rings 62, cover the top plate and tighten it with screws, install the two oil-resistant rubber tubes 93 to the inside of the lubrication port 7, start the active bevel gear 41 and the driven bevel gear 42 to rotate, and during the transmission process, the oil baffle plate 81 realizes the oil baffle operation, and the lubricating oil enters the inside of the guide ring 84 through the annular groove 82. At this time, the lubricating oil flows into the collection plate 91 through the connecting port 85 by gravity, and the collection plate 91 collects the lubricating oil. The special design of the conical plate 92 facilitates the lubricating oil to enter the two oil-resistant rubber tubes 93. The micro pump 94 is started to guide the lubricating oil to the inside of the lubrication port 7, thereby entering the inside of the lip seal 51 of the sealing component 5, and finally entering the inside of the oil baffle plate 81 through the sealing component 5, and re-entering the inside of the collecting plate 91 for collection. Due to the provision of the dynamic ring, when it is necessary to disassemble the sealing component 5, first disassemble the top plate, then take out the oil-resistant rubber tube 93 from the lubrication port 7, press the two inclined plates 64, and the two inclined plates 64 are converted from an inclined state to a parallel state under the action of the spring 63, thereby driving the detachable component 6 and the lip seal 51 to drive the engaging ring 52 to be disassembled from the dynamic ring 1 53 and the dynamic ring 2 55, and finally the sealing component 5 and the detachable component 6 are disassembled and separated from the sealing box body 3 as a whole. At this point, the entire workflow is completed.
