During operation, heavy-duty reducers need to withstand high loads, high torques, and complex and changing working conditions. As an important component of heavy-duty reducer, the housing not only provides support and protection for internal gears, shafts and other transmission components, but also needs to have good sealing performance to ensure the normal operation of the reducer.

[0003] The existing transmission device is unable to combine the sealing structure with the lubrication component, resulting in the inability to effectively lubricate the inside of the sealing component near the reducer, and it is inconvenient to deal with oil stains when disassembling the sealing component, 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 reducer housing with an efficient sealing structure. Summary of the Invention

[0025] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0026] 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.

[0027] In modern industrial transmission systems, high requirements are placed on the performance, reliability and maintenance convenience of transmission devices. Existing transmission devices have obvious deficiencies in the combination of sealing structures and lubrication components. On the one hand, the design of the sealing structure focuses on preventing medium leakage, but it is difficult to work in conjunction with the lubrication component. For example, common seals such as O-rings and lip seals have the main function of preventing internal lubricating oil from leaking and external impurities from entering. However, there are limitations in lubrication. The lubricating oil cannot be effectively guided into the interior of 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 up independently, such as oil pool lubrication and oil mist lubrication, which makes it difficult to accurately provide continuous and stable lubrication for the sealing component. This separate design prevents the lubricating oil from fully exerting its lubricating effect, easily causing lubricating oil waste and leakage, increasing equipment maintenance costs and environmental pollution risks. In addition, in actual applications, when the sealing component needs to be disassembled for maintenance, the existing structure makes it difficult to conveniently disassemble and clean the lubricating oil, further affecting the maintenance efficiency and operational stability of the equipment. The present invention discloses a heavy-duty reducer housing with an efficient sealing structure. Please refer to the attached figure. 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 guide component 8 connected to the lubricating component 9, the sealing component 5 includes a lip sealing ring 51, a fitting ring 52, a dynamic ring 1 53, a groove 54 and a dynamic ring 2 55, the fitting ring 52 is arranged on the lip sealing ring 51, the fitting ring 52 is provided with a lubrication port 7, the groove 54 is provided inside the dynamic ring 1 53, the dynamic ring 2 55 and the dynamic ring 1 53 match each other, the dynamic ring 2 55 and the dynamic ring 1 53 are both provided with a through groove 56, the fitting ring 52 runs through the two through grooves 56, when the lubricating oil enters the interior of the lubrication port 7, the lubricating oil enters the interior of the dynamic ring 1 53 and the dynamic ring 2 55 from the interior of the fitting ring 52 to achieve lubrication, the guide component 8 includes an oil baffle plate 81, the oil baffle plate An annular groove 82 is provided inside 81, a guide ring 84 is provided at the bottom of the oil baffle plate 81, an oil seepage port 83 is provided between the guide ring 84 and the oil baffle plate 81, a hollow structure is provided inside the guide ring 84, the guide ring 84 has a semicircular cross-section, and a guide protrusion is provided on the inner wall, and two connecting ports 85 are provided on the bottom surface of the guide ring 84. The lubrication assembly 9 includes a collecting plate 91 and a conical plate 92. The front and back surfaces of the collecting plate 91 are both provided with an oil-resistant rubber tube 93, and a micro pump 94 is provided on the oil-resistant rubber tube 93. The conical plate 92 is provided inside the collecting plate 91. By setting the special shape of the conical plate 92, the lubricating oil is guided into both sides of the collecting plate 91, and the lubricating oil is conveniently guided to the sealing assembly 5 through the oil-resistant rubber tube 93 to lubricate the sealing assembly 5, thereby ensuring a good sealing effect and adapting to different working conditions.

[0028] Embodiment 1: A base 2 is provided at the bottom of the structural body 1, and a sealed box 3 is provided on the base 2. Grooves are provided on the front and back of the sealed box 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 provided inside the groove, the two sealing rings 62 are respectively provided on the inner and outer sides of the sealed box 3, and the two inclined plates 64 are respectively provided on the left and right sides of the clamping plate 61 through the spring 63;

[0029] Specifically, by arranging 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, the top plate is removed and the two inclined plates 64 are pressed. The two inclined plates 64 are converted from an inclined state to a parallel state under the action of the spring 63, thereby facilitating the removal and separation of the sealing component 5 and the detachable component 6 from the sealing box body 3.

[0030] In the second embodiment, a transmission device 4 is provided inside the sealed box 3. The transmission device 4 includes a driving bevel gear 41. Two driven bevel gears 42 are meshed on the driving bevel gear 41. Holes are formed in the inner centers of the lip seal 51, the interlocking ring 52, the first dynamic ring 53 and the second dynamic ring 55.

[0031] Specifically, by providing a lip seal 51, the lubricating oil can be effectively prevented from leaking from the joint between the sealing box 3 and the transmission device 4. Its lip fits tightly with the relatively moving parts and can adapt to a certain degree of axial and radial displacement to ensure the sealing effect. The internal center holes of the lip seal 51, the chimeric ring 52, the dynamic ring 1 53 and the dynamic ring 2 55 allow the shaft to pass through smoothly without affecting the rotation effect of the shaft.

[0032] Specifically, the setting of the chimeric 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 chimeric ring 52 correspond to the holes of the lip seal ring 51, ensuring the installation accuracy and stability of the shaft, and the dynamic ring 1 53 and the dynamic ring 2 55 realize dynamic sealing. The holes inside the dynamic ring 1 53 and the dynamic ring 2 55 are also used for the installation of the shaft, and when the shaft rotates, the dynamic ring 1 53 and the dynamic ring 2 55 can fit tightly to prevent lubricating oil leakage.

[0033] Specifically, the transmission and direction change of power are achieved by providing a driving bevel gear 41 and two driven bevel gears 42. When the driving bevel gear 41 rotates, the driven bevel gears 42 are driven to rotate through the meshing of the tooth surfaces, providing power output for the entire transmission device 4. During operation, the friction and wear during gear meshing are effectively reduced, thereby improving transmission efficiency and reliability.

[0034] Embodiment 3: Heat dissipation grooves are provided on the left and right sides of the base 2, an opening is provided at the bottom of the sealing box 3, the opening is connected to the base 2, a heat dissipation fan is provided inside the base 2, and fixed bottom plates are provided at the four corners of the base 2, each of the fixed bottom plates is provided with a fastening bolt, a top plate is provided on the top of the sealing box 3, and the top plate is set on the sealing box 3 by screws, the lip sealing ring 51 and the sealing ring 62 are made of rubber, the number of sealing components 5, detachable components 6 and lubrication components 9 are all set to two, the semicircular design of the guide ring 84 can reduce the flow resistance of the oil, and the hollow structure is used to accommodate the return lubricating oil.

[0035] Specifically, a connecting plate is provided between the detachable assembly 6 and the sealing assembly 5. The sealing assembly 5 and the lubrication assembly 9 are connected via an oil-resistant rubber tube 93. The lubrication assembly 9 and the guide assembly 8 are connected via a guide ring 84. The lubricating oil flows from the guide ring 84 into the interior of the collection tray 91. The lubricating oil is guided into the interior of the sealing assembly 5 by a micro pump 94. When the lubricating oil enters the interior of the lubrication port 7, the lubricating oil flows from the interior of the fitting ring 52 into the interiors of the movable ring 1 53 and the movable ring 2 55, respectively, to achieve lubrication.

[0036] Specifically, a collecting tray 91 is provided to collect the lubricating oil, and the design of the conical plate 92 facilitates the lubricating oil to enter the interior of the two oil-resistant rubber tubes 93. The micro pump 94 is activated to guide the lubricating oil to the interior of the lubrication port 7, thereby guiding the lubricating oil to the interior of the lip seal 51 of the sealing assembly 5. The lubricating assembly 9 and the sealing assembly 5 are combined to facilitate effective lubrication of the interior of the sealing assembly 5 near the reducer.

[0037] Specifically, by removing the oil-resistant rubber tube 93 from the lubrication port 7, pressing the inclined plate 64, the spring 63 is compressed, and the inclined plate 64 is turned from an inclined state to a parallel state, thereby driving the detachable component 6 and the lip seal 51 to drive the engaging ring 52 to be removed from the driven ring 1 53 and the driven ring 2 55, so as to achieve the effect of processing the lubricating oil while removing the sealing component 5, thereby 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;

[0038] Specifically, by setting the lip seal 51, the dynamic ring 1 53 and the dynamic ring 2 55 in the sealing component 5, multiple sealing effects are achieved to prevent leakage of lubricating oil, and the setting of the lubricating component 9 is set to lubricate the sealing component 5 while achieving sealing. The lubricating oil eventually enters the interior of the oil baffle 81 through the sealing component 5 and re-enters the interior of the collection plate 91 for collection, which not only reduces the friction resistance, but also takes away the heat generated by friction, while ensuring a good lubrication effect, avoiding waste of lubricating oil.

[0039] Working principle:

[0040] 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 81 realizes the oil blocking 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 81 through the sealing component 5, and re-entering the inside of the collection tray 91 for collection. Due to the provided dynamic ring, when it is necessary to disassemble the sealing component 5, first disassemble the top plate, 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. 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.
