Description

Technical Field

[0001] This invention relates to the technical field of gearboxes. More specifically, this invention relates to a synchronous gearbox with a high-efficiency cooling cycle. Background Technology

[0002] Gearboxes generate a significant amount of heat during operation. When a gearbox operates under overload for an extended period, this heat cannot be dissipated in time, causing the temperature of the oil inside the gearbox to gradually rise. This leads to a gradual increase in oil pressure, eventually causing some oil to seep out from the gaps in the gearbox, resulting in oil leakage. The decrease in the amount of oil inside the gearbox interferes with its operation, and oil leaks onto the ground also cause environmental pollution. Current technology involves installing a pressure sensor inside the gearbox to monitor the oil pressure. When an increase in pressure is detected, the cooling system is activated to cool the oil. This process requires multiple electrical components and control programs, resulting in low efficiency and a high failure rate. Summary of the Invention

[0003] To overcome the shortcomings of existing equipment that requires multiple electrical components and electrical control programs to cool the oil inside the gearbox, resulting in low efficiency and high failure rate, this invention provides a synchronous gearbox with a high-efficiency cooling cycle.

[0004] Technical solution

[0005] A synchronous gearbox with a high-efficiency cooling cycle includes a housing 1, a housing 2, and a transmission mechanism. Housing 2 is fixedly connected to housing 1. The transmission mechanism is connected between housing 1 and housing 2, and is used to receive and output power. It also includes a heat-conducting plate, elastic telescopic rods, a movable plate, a linkage block, a spring 1, and pipes. The heat-conducting plate is fixedly connected to housing 1. Several elastic telescopic rods are fixedly connected to the heat-conducting plate. The telescopic ends of all elastic telescopic rods are fixedly connected to a movable plate, which is slidably connected to housing 1. Several linkage blocks are slidably connected to the heat-conducting plate. Several spring 1s are fixedly connected to each linkage block, and the spring 1s are fixedly connected to the heat-conducting plate. A groove 1 is formed on the heat-conducting plate. Two grooves 2 are formed on housing 1, which communicate with groove 1. One groove 2 is used for coolant input, and the other groove 2 is used for coolant discharge. Two pipes are fixedly connected to housing 1, and the pipes communicate with the corresponding grooves 2. Each linkage block has a through hole.

[0006] As a further preferred option, the groove is wavy.

[0007] As a further preferred option, a sealing ring is provided between box one and box two.

[0008] As a further preferred option, a sealing ring is provided between the housing and the movable plate.

[0009] As a further preferred option, it also includes heat-conducting strips; several heat-conducting strips are fixedly attached to the movable plate; and several grooves are formed on the heat-conducting plate.

[0010] As a further preferred option, the distribution density of the heat-conducting strips increases, and the heat-conducting strips are more densely packed on the side near the groove 2 used for draining coolant.

[0011] As a further preferred embodiment, it also includes a fixing component; the fixing component is connected to the housing; the fixing component includes an L-shaped block, a second spring, and a fixing block; several L-shaped blocks are slidably connected to the housing; the L-shaped blocks have inclined surfaces; several second springs are fixedly connected to each L-shaped block, and the second springs are fixedly connected to the housing; several fixing blocks are fixedly connected to the movable plate, and the fixing blocks cooperate with the corresponding L-shaped blocks.

[0012] As a further preferred option, a sealing ring is provided between the housing and the L-shaped block.

[0013] As a further preferred option, both the L-shaped block and the fixing block are made of wear-resistant material.

[0014] As a further preferred option, both the outer surfaces of box one and box two are coated with an anti-corrosion layer.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. By utilizing changes in oil temperature and pressure, the opening of groove one is automatically controlled, allowing the coolant to circulate within groove one to cool the oil, thereby reducing the oil pressure and minimizing the risk of oil leakage. This process does not require the use of electrical controls and programs, resulting in high efficiency and a low failure rate. Furthermore, during the process of controlling the opening of groove one using oil pressure, the oil pressure pushes the movable plate downward, increasing the volume between housing one and housing two, which helps to reduce oil pressure and further reduce the risk of oil leakage.

[0017] Second, by setting heat-conducting strips between the heat-conducting plate and the movable plate, the heat exchange area is increased, thereby improving the cooling effect. At the same time, a denser heat-conducting strip is set at the rear to improve the cooling effect on the oil at the rear, avoiding the problem of poor cooling effect of the oil at the rear.

[0018] Third, during normal use, the moving plate is fixed by the cooperation of the L-shaped block and the fixed block. Even if the moving plate is impacted by oil, it will not move downward, thus avoiding the problem of low service life caused by the high frequency of up and down sliding of the moving plate.

Detailed Implementation

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: A synchronous gearbox with a high-efficiency cooling cycle, such as Figures 1-6As shown, it includes a housing 1, a housing 2, and a transmission mechanism 3; housing 2 is bolted to housing 1, and both housing 1 and housing 2 are made of alloy material; the transmission mechanism 3 connects housing 1 and housing 2 together; it also includes a heat-conducting plate 4, elastic telescopic rods 5, a movable plate 6, a linkage block 7, a spring 8, and a pipe 13; the heat-conducting plate 4 is bolted to housing 1; four elastic telescopic rods 5 are fixed to the heat-conducting plate 4; the telescopic ends of all the elastic telescopic rods 5 are fixed to the movable plate 6, which slides against housing 1. Connection; two linkage blocks 7 are slidably connected to the heat-conducting plate 4; two springs 8 are fixedly connected to each linkage block 7, and the springs 8 are fixedly connected to the heat-conducting plate 4; a groove 91 is provided on the heat-conducting plate 4; two grooves 92 are provided on the housing 1, and the grooves 92 are connected to the grooves 91. One groove 92 is used for inputting coolant, and the other groove 92 is used for discharging coolant; two pipes 13 are bolted to the housing 1, and the pipes 13 are connected to the corresponding grooves 92; a through hole 93 is provided on each linkage block 7.

[0031] The groove 91 is wavy, which can prolong the time it takes for the coolant to flow through the groove 91, thereby improving the cooling effect.

[0032] A sealing ring is provided between box 1 and box 2 to improve the sealing performance.

[0033] A sealing ring is provided between the housing 1 and the movable plate 6 to improve the sealing performance.

[0034] First, an external coolant circulation system is connected to two pipes 13. Coolant is supplied to the forward pipe 13 via this system. The coolant flows through the forward pipe 13 into the forward groove 92, and then into the end of the first groove 91. At this point, the linkage block 7 intercepts the coolant, preventing it from flowing further into the first groove 91. When the oil pressure between housing 1 and housing 2 increases, the oil pushes the movable plate 6 downwards, compressing the elastic telescopic rod 5. The movable plate 6 pushes the linkage block 7 downwards, compressing the spring 8 until the through hole 93 on the linkage block 7 aligns with the groove 91. At this point, the linkage block 7 stops blocking the groove 91, allowing coolant to flow in from the front port of the groove 91, then out from the rear port, and into the rear groove 92. From there, it flows back into the external coolant circulation system through the rear pipe 13. After the movable plate 6 moves downwards, it contacts the heat-conducting plate 4. At this point, the heat from the oil inside the housing 1 and housing 2 is transferred to... The oil is heated on the movable plate 6, then transferred to the heat-conducting plate 4, and then to the coolant, thus achieving emergency cooling of the oil. As the oil temperature drops, its pressure also drops, causing the pressure of the oil on the movable plate 6 to decrease. This causes the elastic telescopic rod 5 to rebound, moving the movable plate 6 back to its original position. The spring 8 rebounds, moving the linkage block 7 back to its original position, causing the linkage block 7 to re-seal the groove 91, stopping the emergency cooling operation. That is, by using changes in oil temperature and pressure, the opening of the groove 91 is automatically controlled, allowing the coolant to circulate inside the groove 91 to cool the oil, thereby reducing the oil pressure and decreasing the risk of oil leakage. This process does not require the use of electrical controls and programs, resulting in high efficiency and a low failure rate. Furthermore, during the process of controlling the opening of the groove 91 using oil pressure, the oil pressure pushes the movable plate 6 downward, increasing the volume between the housing 1 and the housing 2, which helps to reduce the oil pressure and further reduce the risk of oil leakage.

[0035] Example 2: Based on Example 1, such as Figure 4 and Figure 7 As shown, it also includes heat-conducting strips 9; several heat-conducting strips 9 are welded to the lower side of the movable plate 6; several grooves 94 are opened on the heat-conducting plate 4.

[0036] The distribution density of the heat-conducting strips 9 increases progressively, and the heat-conducting strips 9 are denser on the side near the groove 2 92 used for draining coolant.

[0037] As the movable plate 6 moves downward, it will also drive the heat-conducting strip 9 downward, so that the heat-conducting strip 9 is inserted into the groove 3 94. During heat dissipation, heat is transferred between the heat-conducting plate 4, the movable plate 6 and the heat-conducting strip 9, which increases the heat exchange area and helps to improve the cooling efficiency.

[0038] Since the coolant flows in from the front port of groove 91 and out from the rear port of groove 91, the coolant absorbs heat throughout the entire process of flowing through groove 91. As a result, the temperature of the coolant located at the rear inner side of groove 91 is always higher than that of the coolant located at the front inner side of groove 91, which leads to low cooling efficiency for the oil at the rear. Therefore, denser heat-conducting strips 9 are installed at the rear to increase the heat exchange area at the rear, thereby improving the cooling effect on the oil at the rear.

[0039] Example 3: Based on Example 2, as follows Figure 3 and Figure 8 As shown, it also includes a fixing component; the fixing component is connected to the housing 1; the fixing component includes an L-shaped block 10, a spring 11, and a fixing block 12; two L-shaped blocks 10 are slidably connected to the housing 1; the L-shaped blocks 10 have inclined surfaces; two springs 11 are fixedly connected to each L-shaped block 10, and the springs 11 are fixedly connected to the housing 1, and the springs 11 are made of alloy material; two fixing blocks 12 are bolted to the movable plate 6, and the fixing blocks 12 cooperate with the corresponding L-shaped blocks 10. When the oil pressure between the housing 1 and the housing 2 increases, the oil pressure pushes the L-shaped blocks 10 to move, and the L-shaped blocks 10 compress the springs 11.

[0040] A sealing ring is provided between the housing 1 and the L-shaped block 10 to improve the sealing performance.

[0041] Both the L-shaped block 10 and the fixing block 12 are made of wear-resistant material to improve their service life.

[0042] Both enclosure 1 and enclosure 2 have an anti-corrosion coating on their outer surfaces for rust prevention.

[0043] In normal use, the transmission mechanism 3 consists of multiple gears. During gear rotation, the gears agitate the hydraulic fluid, causing it to irregularly impact the movable plate 6. Upon impact, the movable plate 6 moves downwards, compressing the elastic telescopic rod 5. As the impact decreases, the elastic telescopic rod 5 rebounds, causing the movable plate 6 to move upwards. However, the high gear speed, meaning the high frequency of agitating the hydraulic fluid, results in a high frequency of impact on the movable plate 6, leading to a high frequency of up-and-down sliding of the movable plate 6. This accelerates the wear of the sealing ring between the housing 1 and the movable plate 6, thus reducing its service life. Therefore, in normal use, the movable plate 6 is fixed in place by the L-shaped block 10 and the fixing block 12. Even when impacted by hydraulic fluid, the movable plate 6 will not move downwards, thus avoiding the reduced service life caused by the high frequency of up-and-down sliding of the movable plate 6. The problem is that when the oil pressure increases, the oil pushes the L-shaped block 10 to move horizontally and compresses the second spring 11, causing the L-shaped block 10 to move away from the fixed block 12 and stop fixing the fixed block 12. At this time, the oil can push the movable plate 6 downward, thereby performing oil cooling operation. After the oil pressure returns to normal, the second spring 11 rebounds and drives the L-shaped block 10 to move back to its original position. The elastic telescopic rod 5 rebounds and drives the movable plate 6 to move upward. The movable plate 6 drives the fixed block 12 to move upward. The fixed block 12 moves upward and contacts the inclined surface of the L-shaped block 10. The fixed block 12 continues to push the L-shaped block 10 to move horizontally and compresses the second spring 11. When the fixed block 12 passes the inclined surface of the L-shaped block 10, the second spring 11 rebounds and drives the L-shaped block 10 to move back to its original position, so that the L-shaped block 10 and the fixed block 12 re-engage and fix the movable plate 6.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
