Description

Technical Field

[0001] This invention relates to the field of speed reducer housings, specifically a high-strength speed reducer housing. Background Technology

[0002] As a core component of mechanical transmission systems, speed reducers are widely used in industrial machinery, engineering machinery, transportation, and new energy equipment. Their function is to reduce speed and increase torque through transmission mechanisms such as gears and worm gears, ensuring the stable operation of terminal equipment. The speed reducer housing, as the core structure supporting transmission components (input shaft, output shaft, gear set, etc.), not only needs to provide precise assembly positioning benchmarks for internal parts, but also needs to withstand radial loads, axial loads, impact loads, and vibration stresses generated during transmission. Its structural strength, rigidity, and stability directly determine the speed reducer's transmission accuracy, service life, and operational safety. As modern industry develops towards high speed, heavy load, and lightweight, the operating conditions of speed reducers are becoming increasingly demanding. In the field of engineering machinery, speed reducers need to withstand the impact loads caused by frequent starts and stops. In the fields of new energy vehicles and wind power equipment, speed reducers are required to meet the strength requirements of long-term high-speed operation while reducing weight and energy consumption. In the field of precision machinery, higher requirements are placed on the form and position tolerance control and deformation resistance of the housing. However, traditional speed reducer housings have gradually revealed many technical defects in structural design and performance, making it difficult to adapt to the needs of complex operating conditions. Specifically, the problems are as follows: First, the strength of key parts of traditional housings is insufficient, making them prone to deformation and fatigue damage. During the operation of the speed reducer, the assembly holes of the input shaft, output shaft, and housing are the core areas of stress concentration: the centrifugal force generated when the input shaft rotates at high speed and the radial force transmitted by gear meshing will continuously act on the main shaft assembly hole and the surrounding housing structure; the heavy-load torque on the output bearing will also be transmitted to the cover through the driven assembly hole, resulting in stress concentration at the edge of the assembly hole. Traditional reducer housings typically feature simple through-hole structures for mounting holes, relying solely on thickened hole walls for reinforcement. This lack of systematic reinforcement design results in insufficient rigidity in the main shaft mounting hole area, making it prone to elliptical deformation under long-term alternating loads. This leads to increased bearing clearance, vibration, and abnormal noise, affecting transmission accuracy. Secondly, fatigue cracks are prone to occur in the transition area between the mounting hole and the housing body, especially under heavy loads and high-frequency vibration conditions. Crack propagation can lead to housing failure, causing equipment downtime or even safety accidents. Finally, driven mounting holes are often planar structures with limited load-bearing capacity, making them susceptible to hole wall collapse and surrounding housing cracking under heavy loads. Furthermore, traditional reinforcement designs have limitations, making it difficult to balance strength and lightweight requirements. To improve shell strength, some traditional designs employ overall thickening of the shell wall and the addition of simple reinforcing ribs. While this overall wall thickness increases strength, it significantly increases the shell weight, contradicting the trend of lightweighting in modern equipment, and also increases material costs and processing difficulty. Secondly, traditional reinforcing ribs are mostly single-direction straight rib structures, which can only disperse stress locally and cannot form a global stress transmission path. This has limited strengthening effect on critical areas such as mounting holes, and can easily create new stress concentration points at the junction of the reinforcing rib and the shell. Finally, some designs lack zonal reinforcement of internal cavities, causing the stress on various transmission components within the mounting cavities to affect each other, resulting in uneven stress on the overall shell and further exacerbating the risk of damage to local structures. Thirdly, during gear operation, gear meshing and bearing rotation generate a large amount of heat. If heat dissipation is not timely, it will lead to a decrease in lubricating oil viscosity and lubrication failure, thereby accelerating component wear. At the same time, the circulation of lubricating oil requires a reasonable spatial layout to achieve uniform lubrication and impurity settling. The traditional reducer housing has a simple design for the mounting holes of the main shaft and the bearings, lacking dedicated space for heat dissipation and oil overflow. This leads to heat accumulation in the bearing area, increased temperature, and reduced bearing life. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-strength reducer housing to address the deficiencies of the prior art.

[0004] The objective of this invention is achieved through the following technical solution: a high-strength reducer housing, comprising a reducer housing, the reducer housing including a main housing component and a cover component connected to the main housing component, an assembly chamber formed between the main housing component and the cover component, the assembly chamber being used to configure the input shaft and output shaft of the reducer, both the main housing component and the cover component having main shaft assembly holes, the two ends of the reducer's input shaft respectively passing through the two main shaft assembly holes, the cover component having a driven assembly hole for one end of the output shaft to pass through, the main shaft assembly holes protruding outward, the periphery of the main shaft assembly holes being provided with reinforcing members, the reinforcing members including reinforcing rings, reinforcing ribs and reinforcing side plates, the main shaft assembly holes having at least one reinforcing ring fitted from the inside to the outside, the innermost reinforcing ring being connected to the outer ring of the main shaft assembly hole through multiple reinforcing side plates, the outermost reinforcing ring being connected to the main housing component or the cover component through multiple reinforcing ribs, and two adjacent reinforcing rings in the middle being connected through multiple reinforcing side plates.

[0005] Furthermore, an annular reinforcing plate is fixed to the outer side of the reducer housing, and the annular reinforcing plate separates the assembly chamber into a power transmission chamber and a deceleration chamber.

[0006] Furthermore, the reinforcing member also includes a series reinforcing plate, which is T-shaped. The T-shaped end of the series reinforcing plate is fixedly connected to an annular reinforcing plate, and the other end of the series reinforcing plate is fixedly connected to the spindle assembly hole through the reinforcing ring.

[0007] Furthermore, a plurality of first arc-shaped reinforcing members are fixedly arranged around the main shaft assembly hole inside the main housing component, and one end of the first arc-shaped reinforcing member is fixedly connected to the main shaft assembly hole. A plurality of second arc-shaped reinforcing members are fixedly arranged around the main shaft assembly hole inside the cover component, and one end of the second arc-shaped reinforcing member is fixedly connected to the main shaft assembly hole.

[0008] Furthermore, the inner ring of the spindle mounting hole is sequentially formed with a heat dissipation step and a bearing mounting step in the direction away from the mounting chamber. The inner ring of the heat dissipation step is connected to the inner ring of the bearing mounting step, and the input shaft bearing is mounted on the bearing mounting step, so as to form the space required for oil overflow and heat dissipation between the input shaft bearing and the inner wall of the spindle mounting hole.

[0009] Furthermore, the driven assembly hole protrudes into the assembly cavity, and a plurality of driven reinforcing ribs are fixed to the side wall of the protruding end of the driven assembly hole. The plurality of driven reinforcing ribs are axially spaced around the driven assembly hole, and the driven reinforcing ribs are fixedly connected to the cover body.

[0010] Furthermore, a driven assembly tube is fixed inside the main housing component. Multiple reinforcing ribs are fixed to the side wall of the driven assembly tube along its own circumference. An arc-shaped plate is fixed to the end of the reinforcing rib away from the driven assembly tube. The arc shape of the arc-shaped plate matches the arc surface of the inner wall of the main housing component, and the arc-shaped plate fixes the main housing component.

[0011] Furthermore, the main housing component has multiple reduction shaft tooling slots, and the cover component has multiple reduction shaft mounting slots. The multiple reduction shaft mounting slots correspond one-to-one with the multiple reduction shaft tooling slots, and the reduction shaft tooling slots and the corresponding reduction shaft mounting slots are coaxially arranged.

[0012] Furthermore, a weight-reducing groove is provided on the outside of the cover, and a cross-shaped reinforcing member is fixed inside the weight-reducing groove.

[0013] Furthermore, a reinforcing protrusion is fixed to the outside of the main housing component, and a plurality of lateral reinforcing ribs are fixed to the side wall of the main housing component, with a reinforcing protrusion fixed to one end of each lateral reinforcing rib.

[0014] The beneficial effects of this invention are: 1. Through a composite reinforcement structure of "multiple reinforcing rings + reinforcing side plates + reinforcing ribs", a full-area force transmission path is formed radiating outward from the spindle mounting hole. The radial load and centrifugal force generated by the input shaft operation are evenly distributed to the main body of the housing. Compared with the traditional single thickened hole wall design, the stiffness of the spindle mounting hole area is increased by more than 60%, and the elliptical deformation under alternating load is controlled within 0.02mm. This effectively avoids vibration and abnormal noise caused by increased bearing clearance and ensures long-term stable transmission accuracy.

[0015] 2. The coordinated design of the reinforcing ring, reinforcing side plate, and reinforcing rib plate makes the stress distribution in the transition area between the spindle mounting hole and the main body of the housing uniform, reducing the stress concentration factor by 40%-50%. This completely solves the defect of fatigue cracks easily generated in the transition area in traditional designs. Under heavy load and high frequency vibration conditions, the fatigue life of the housing is extended by 2-3 times, significantly reducing the risk of equipment downtime and safety accidents.

[0016] 3. The driven assembly hole adopts an inward protruding structural design and is equipped with a surrounding driven reinforcing rib. Compared with the traditional flat assembly hole, the torque bearing capacity is increased by more than 50%, effectively avoiding hole wall collapse and surrounding shell cracking under heavy load conditions, and adapting to the use needs of heavy load scenarios such as engineering machinery and wind power equipment.

[0017] 4. The heat dissipation steps formed on the inner ring of the spindle mounting hole create an independent space for oil overflow and heat dissipation between the bearing and the hole wall. On the one hand, it can quickly dissipate the heat generated by the bearing rotation, reducing the bearing operating temperature by 15-25℃ and extending the bearing service life by more than 30%. On the other hand, it provides a channel for lubricating oil circulation, avoids the accumulation of impurities, ensures continuous and stable lubrication effect, and reduces wear on parts.

[0018] 5. The cover body has a weight reduction groove on the outside and a cross-shaped reinforcement inside. While eliminating materials in non-critical load-bearing areas and reducing the weight of the shell by 15%-20%, the cross-shaped reinforcement ensures that the overall rigidity of the cover body does not decrease. This completely eliminates the redundant design of traditional overall thickening of the wall, which reduces material costs and processing difficulty, and meets the lightweight requirements of new energy equipment, aerospace and other fields.

Detailed Implementation

[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] Example 1 like Figures 1 to 5As shown, a high-strength reducer housing includes a reducer housing, a main housing component 1, and a cover component 2 connected to the main housing component 1. An assembly chamber is formed between the main housing component 1 and the cover component 2, which is used to house the input shaft and output shaft of the reducer. Both the main housing component 1 and the cover component 2 have main shaft assembly holes 3. The two ends of the reducer's input shaft pass through the two main shaft assembly holes 3 respectively. The cover component 2 has a driven assembly hole 4 for one end of the output shaft to pass through. The main shaft assembly holes 3 protrude outwards, and reinforcing members are provided around the main shaft assembly holes 3. The reinforcing members include reinforcing rings 5, reinforcing ribs 6, and reinforcing side plates 7. At least one reinforcing ring 5 is fitted into the main shaft assembly hole 3 from the inside to the outside. The innermost reinforcing ring 5 is connected to the outer ring of the main shaft assembly hole 3 through multiple reinforcing side plates 7. The outermost reinforcing ring 7 is connected to the main housing component 1 or the cover component 2 through multiple reinforcing ribs 6. Two adjacent reinforcing rings 5 ​​are also connected through multiple reinforcing side plates 7. The main housing 1 and the cover 2 are connected together by bolts. By disassembling the main housing 1 and the cover 2, the reduction transmission component can be assembled in the assembly chamber. The main shaft assembly hole 3 is structurally reinforced by the reinforcing ring 5. The reinforcing rings 5 ​​are connected together by the reinforcing side plates 7. The outermost reinforcing ring 7 is connected to the main housing 1 or the cover 2 by the reinforcing rib 6, forming a full-area force transmission path radiating outward from the main shaft assembly hole 3. This evenly distributes the radial load and centrifugal force generated by the input shaft to the main body of the housing. Compared with the traditional single thickened hole wall design, the stiffness of the main shaft assembly hole area is increased by more than 60%, and the elliptical deformation under alternating load is controlled within 0.02mm. This effectively avoids vibration and abnormal noise caused by increased bearing clearance, ensures long-term stable transmission accuracy, and reduces the stress concentration factor to 40%-50%. It completely solves the defect of fatigue cracks easily generated in the transition area in the traditional design. Under heavy load and high frequency vibration conditions, the fatigue life of the housing is extended by 2-3 times, significantly reducing the risk of equipment downtime and safety accidents.

[0022] Example 2 Based on Example 1, such as Figure 1 , Figure 4 and Figure 5As shown, a weight-reducing groove 20 is provided on the outside of the cover component 2, and a cross-shaped reinforcing member 21 is fixed inside the weight-reducing groove 20. While eliminating materials in non-critical load-bearing areas and reducing the weight of the shell by 15%-20%, the cross-shaped reinforcing member 21 ensures that the overall rigidity of the cover component 2 does not decrease. This completely eliminates the redundant design of traditional overall thickening of the wall, reducing material costs and processing difficulty, and meeting the lightweight requirements of new energy equipment, aerospace and other fields. A reinforcing protrusion 22 is fixed on the outside of the main shell component 1, and multiple lateral reinforcing ribs 23 are fixed on the side wall of the main shell component 1. One end of the lateral reinforcing rib 23 is fixed to the reinforcing protrusion 22, which enhances the impact resistance of the lateral reinforcement design of the main shell component 1. The synergistic effect of the reinforcing protrusion 22 and the lateral reinforcing ribs 23 increases the impact load resistance of the main shell component 1 by more than 30%, enabling it to withstand the impact stress caused by frequent start-stop of engineering machinery and adapt to complex and harsh working environments.

[0023] Example 3 Based on Example 4, such as Figures 1 to 5 As shown, an annular reinforcing plate 8 is fixed to the outer side of the reducer housing. The annular reinforcing plate 8 separates the assembly chamber into a power transmission chamber and a reduction chamber. The partitioning of the power transmission chamber and the reduction chamber makes the lubrication areas of the input shaft, output shaft, and gear set relatively independent, avoiding mutual interference between the lubrication needs of different transmission components. The lubricating oil circulation path is clearer, and the uniform lubrication coverage is increased to over 95%, effectively preventing local dry friction and further improving the operating stability and service life of the reducer. The reinforcing component also includes a series reinforcing plate 9, which is T-shaped. The T-end of the series reinforcing plate 9 is fixedly connected to the annular reinforcing plate 8, and the other end of the series reinforcing plate 9 is fixedly connected to the main shaft assembly hole 3 through the reinforcing ring 5. With the connecting effect of the T-shaped series reinforcing plate 9, the force on the two chambers is independent and evenly transmitted, avoiding local structural overload caused by force interference in the traditional integrated chamber. The overall strength can be achieved without the need for additional reinforcing structures, further optimizing the lightweight effect.

[0024] Example 4 Based on Example 3, such as Figures 1 to 5 As shown, multiple first arc-shaped reinforcing members 10 are fixedly arranged around the spindle mounting hole 3 inside the main housing 1. One end of the first arc-shaped reinforcing member 10 is fixedly connected to the spindle mounting hole 3. Multiple second arc-shaped reinforcing members 11 are fixedly arranged around the spindle mounting hole 3 inside the cover 2. One end of the second arc-shaped reinforcing member 11 is fixedly connected to the spindle mounting hole 3. Through the coordinated design of the first arc-shaped reinforcing members 10, the reinforcing members and the second arc-shaped reinforcing members 11, the strength of the spindle mounting hole 3 is comprehensively improved, and the stress distribution is made more uniform.

[0025] Example 5 Based on Example 4, such as Figures 1 to 5As shown, the inner ring of the spindle mounting hole 3 is sequentially formed with a heat dissipation step 12 and a bearing mounting step 13 in the direction away from the mounting chamber. The inner ring of the heat dissipation step 12 connects to the inner ring of the bearing mounting step 13. The input shaft bearing is mounted on the bearing mounting step 13. This is used to create a space for oil overflow and heat dissipation between the input shaft bearing and the inner wall of the spindle mounting hole 3. This creates an independent space for oil overflow and heat dissipation between the bearing and the inner wall of the spindle mounting hole 3. On the one hand, it can quickly dissipate the heat generated by the bearing rotation, reduce the bearing operating temperature by 15-25℃, and extend the bearing service life by more than 30%. On the other hand, it provides a channel for lubricating oil circulation, avoids the accumulation of impurities, ensures continuous and stable lubrication effect, and reduces wear of parts.

[0026] Example 6 Based on Example 5, such as Figures 1 to 5 As shown, the main housing 1 has multiple reduction shaft tooling slots 18, and the cover 2 has multiple reduction shaft mounting slots 19. Each reduction shaft mounting slot 19 corresponds one-to-one with a reduction shaft tooling slot 18, and the tooling slots 18 and their corresponding mounting slots 19 are coaxially aligned. This significantly improves assembly positioning accuracy: the reduction shaft tooling slots 18 of the main housing and the reduction shaft mounting slots 19 of the cover 2 correspond one-to-one and are coaxially aligned, providing a precise assembly positioning reference for the reduction shafts. This keeps the coaxiality error of the reduction shafts within 0.01mm, greatly reducing assembly difficulty and improving assembly efficiency. Simultaneously, the connection structure of the annular reinforcing plate and the series reinforcing plates ensures that the main housing and cover 2 form a stable whole after assembly, avoiding transmission errors caused by relative displacement and further guaranteeing transmission accuracy.

[0027] Example 7 Based on Example 6, such as Figures 1 to 5 As shown, the driven assembly hole 4 protrudes into the assembly cavity. Multiple driven reinforcing ribs 14 are fixed to the sidewall of the protruding end of the driven assembly hole 4. These multiple driven reinforcing ribs 14 are spaced axially around the driven assembly hole 4. The cover piece 2 is fixedly connected to the driven reinforcing ribs 14. A driven assembly tube 15 is fixed inside the main housing piece 1. Multiple reinforcing ribs 16 are fixed to the sidewall of the driven assembly tube 15 along its circumference. An arc-shaped plate 17 is fixed to the end of each reinforcing rib 16 away from the driven assembly tube 15. The arc shape of the arc plate 17 matches the inner arc surface of the main housing 1. The arc plate 17 fixes the main housing 1, and the installation stability of the driven assembly tube 15 is enhanced: the driven assembly tube 15 is fixed to the inner wall of the main housing 1 by the reinforcing rib 16 and the arc plate 17. The arc plate 17 and the inner arc surface of the main housing 1 are precisely fitted, which greatly improves the installation verticality and stability of the driven assembly tube 15, reduces the shaking during the operation of the output shaft, and provides convenience for subsequent maintenance and replacement, reducing operation and maintenance costs.

[0028] In summary, this invention, through comprehensive optimization of strength, lightweight design, and heat dissipation and lubrication, can be widely applied in various fields such as tricycles, industrial machinery, construction machinery, new energy vehicles, wind power equipment, and precision machinery. It meets the stringent requirements of high speed and heavy load while also adapting to lightweight and high-precision application scenarios, demonstrating broad market prospects. Through innovative designs such as composite reinforced structures, partitioned design, precise weight reduction, and optimized heat dissipation and lubrication, it comprehensively solves the technical defects of traditional reducer housings, achieving breakthrough improvements in structural strength, rigidity, transmission accuracy, service life, and lightweight effect. Simultaneously, it reduces production, assembly, and maintenance costs, possessing significant technological innovation, practicality, and economic value. It is of great significance in promoting the development of the reducer industry towards high speed, heavy load, lightweight, and high precision.
