Description

Technical Field

[0001] The present invention relates to the technical field of gearboxes, and more particularly to a synchronous gearbox with an efficient cooling cycle. Background Art

[0002] A large amount of heat is generated during the operation of the gearbox. When the gearbox is overloaded for a long time, the heat generated cannot be discharged in time, causing the temperature of the oil inside the gearbox to gradually rise, thereby causing the oil pressure to gradually rise, and then causing some oil to seep out from the gaps in the gearbox, resulting in oil leakage. When the amount of oil inside the gearbox decreases, it will interfere with its operation, and oil leakage to the ground will also pollute the environment. The existing technology will set a pressure sensor on the inside of the gearbox to monitor the oil pressure through the pressure sensor. When the pressure is detected to increase, the cooling system is controlled to intervene to cool the oil. This process requires the use of multiple electronic components and electronic control programs, which is inefficient and has a high failure rate. Summary of the invention

[0005] As a further preferred solution, the groove 1 is wavy.

[0006] As a further preferred solution, a sealing ring is provided between the first box and the second box.

[0008] As a further preferred solution, it also includes a heat conducting strip; a plurality of heat conducting strips are fixedly connected to the movable plate; and a plurality of grooves are provided on the heat conducting plate.

[0009] As a further preferred solution, the distribution density of the heat-conducting strips increases gradually, and the heat-conducting strips on the side close to the second groove for discharging the coolant are denser.

[0014] Compared with the prior art, the present invention has the following advantages: 1.

In this process, no electric control components and electric control programs are required, which is highly efficient and has a low failure rate. In addition, in the process of controlling the conduction of groove 1 by using oil pressure, the oil pressure will push the movable plate downward, so that the volume between box body 1 and box body 2 becomes larger, which is conducive to reducing the oil pressure and further reducing the risk of oil leakage. Second, the heat exchange area is increased by setting heat conduction strips between the heat conduction plate and the movable plate, thereby improving the cooling effect.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: A synchronous gearbox with efficient cooling cycle, such as Figure 1-Figure 6As shown, it includes a box body 1, a box body 2 and a transmission mechanism 3; the box body 1 is bolted to the box body 2, and the box body 1 and the box body 2 are both made of alloy material; the transmission mechanism 3 is commonly connected between the box body 1 and the box body 2; it also includes a heat conducting plate 4, an elastic telescopic rod 5, a movable plate 6, a linkage block 7, a spring 18 and a pipe 13; the box body 1 is bolted to the heat conducting plate 4; four elastic telescopic rods 5 are fixed to the heat conducting plate 4; the telescopic ends of all the elastic telescopic rods 5 are commonly fixed to the movable plate 6, and the movable plate 6 slides with the box body 1 The heat conducting plate 4 is connected with two linkage blocks 7 in a sliding manner; each linkage block 7 is fixed with two springs 8, and the springs 8 are fixed with the heat conducting plate 4; the heat conducting plate 4 is provided with a groove 91; the box body 1 is provided with two grooves 92, which are connected with the groove 91, wherein one groove 92 is used for inputting coolant, and the other groove 92 is used for discharging coolant; the box body 1 is bolted with two pipes 13, which are connected with the corresponding grooves 92; each linkage block 7 is provided with a through hole 93.

[0019] The groove 1 91 is in a wave shape, which can prolong the time it takes for the coolant to flow through the groove 1 91 , thereby improving the cooling effect.

[0020] A sealing ring is provided between the box body 1 and the box body 2 to improve the sealing performance.

[0021] A sealing ring is provided between the box body 1 and the movable plate 6 to improve the sealing performance.

[0022] First, the external coolant circulation system is connected to the two pipes 13, and the coolant is transported to the front pipe 13 through the external coolant circulation system. The coolant flows into the front groove 2 92 through the front pipe 13, and then flows into the end of the groove 1 91. At this time, the coolant is intercepted by the linkage block 7, and the coolant cannot continue to flow into the groove 1 91. When the oil pressure between the box body 1 and the box body 2 increases, the oil will push the movable plate 6 to move downward and compress the elastic telescopic rod 5, and the movable plate 6 will move downward. The movable plate 6 pushes the linkage block 7 to move downward and compresses the spring 1 8 until the through hole 93 on the linkage block 7 is aligned with the groove 1 91. At this time, the linkage block 7 stops blocking the groove 1 91, so that the coolant flows in from the front port of the groove 1 91, then flows out from the rear port of the groove 1 91, and flows into the groove 2 92 at the rear, and then flows back to the external coolant circulation system from the rear pipe 13. After the movable plate 6 moves downward, it contacts the heat conducting plate 4. At this time, the heat of the oil inside the box 1 and the box 2 2 is transferred to The oil is then transferred to the movable plate 6 by the movable plate 6 and then to the heat conducting plate 4 and then to the coolant by the heat conducting plate 4, thereby realizing emergency cooling of the oil. When the temperature of the oil drops, its pressure will also drop, thereby reducing the pressure value of the oil on the movable plate 6, thereby causing the elastic telescopic rod 5 to rebound and drive the movable plate 6 to move upward back to its original position, and the spring 8 rebounds and drives the linkage block 7 to move back to its original position, so that the linkage block 7 re-blocks the groove 91 and stops the emergency cooling operation, that is, the change of oil temperature and pressure is used to automatically control the conduction of the groove 91, so that the coolant circulates inside the groove 91 to cool the oil, thereby reducing the oil pressure and reducing the risk of oil leakage. In this process, there is no need to use electronic controls and electronic control programs, the efficiency is high and the failure rate is low, and in the process of controlling the conduction of the groove 91 by the oil pressure, the oil pressure will push the movable plate 6 to move downward, so that the volume between the box body 1 and the box body 2 becomes larger, which is conducive to reducing the pressure of the oil and further reducing the risk of oil leakage.

[0023] Embodiment 2: on the basis of embodiment 1, as Figure 4 and Figure 7 As shown, it also includes a heat conducting strip 9; a plurality of heat conducting strips 9 are welded to the lower side of the movable plate 6; and a plurality of grooves 94 are opened on the heat conducting plate 4.

[0024] The distribution density of the heat conducting strips 9 increases gradually, and the heat conducting strips 9 close to the side of the second groove 92 for discharging the coolant are denser.

[0025] During the downward movement of the movable plate 6, the heat conducting strip 9 will also be driven to move downward, so that the heat conducting strip 9 is inserted into the groove three 94. During heat dissipation, heat is transferred between the heat conducting plate 4, the movable plate 6 and the heat conducting strip 9, that is, the heat exchange area is increased, which is beneficial to improving the cooling efficiency.

[0026] Since the coolant flows in from the front port of groove 91 and flows out from the rear port of groove 91, the coolant absorbs heat during the entire process of flowing through groove 91, so that the temperature of the coolant located at the rear inner side of groove 91 is always higher than the temperature of the coolant located at the front inner side of groove 91, resulting in low cooling efficiency for the oil at the rear. Therefore, more densely distributed heat conductive strips 9 are arranged at the rear to increase the heat exchange area at the rear, thereby improving the cooling effect on the oil at the rear.

[0027] Embodiment 3: Based on embodiment 2, Figure 3 and Figure 8 As shown, it also includes a fixing component; a fixing component is connected to the box body 1; the fixing component includes an L-shaped block 10, a spring 2 11 and a fixing block 12; two L-shaped blocks 10 are slidably connected to the box body 1; an inclined surface is provided on the L-shaped block 10; two springs 2 11 are fixedly connected to each L-shaped block 10, the springs 2 11 are fixedly connected to the box body 1, and the springs 2 11 are set to be 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 box body 1 and the box body 2 increases, the oil pressure pushes the L-shaped block 10 to move, and the L-shaped block 10 compresses the spring 2 11.

[0028] A sealing ring is provided between the box body 1 and the L-shaped block 10 to improve the sealing performance.

[0029] The L-shaped block 10 and the fixing block 12 are both made of wear-resistant material to increase their service life.

[0030] The outer surfaces of the box body 1 and the box body 2 are coated with an anti-corrosion layer to prevent rust.

[0031] During normal use, the transmission mechanism 3 is composed of a plurality of gears, and the oil will be moved during the rotation of the gears, so that the oil will irregularly impact the movable plate 6. After the movable plate 6 is impacted, it will move downward and compress the elastic telescopic rod 5. After the impact on the movable plate 6 is reduced, the elastic telescopic rod 5 rebounds and drives the movable plate 6 to move upward. The rotation speed of the gears is high, that is, the frequency of the oil movement is high, so that the frequency of the oil impacting the movable plate 6 is high, so that the frequency of the movable plate 6 sliding up and down is high, which leads to accelerated wear of the sealing ring between the box body 1 and the movable plate 6, and thus reduces the service life. Therefore, during normal use, the movable plate 6 is fixed by cooperating with the L-shaped block 10 and the fixed block 12. Even if the movable plate 6 is impacted by the oil, the movable plate 6 will not move downward, thereby avoiding the service life caused by the high frequency of the movable plate 6 sliding up and down. When the oil pressure increases, the oil pushes the L-shaped block 10 to move horizontally and compresses the spring 2 11, so that the L-shaped block 10 moves away from the fixed block 12 and stops fixing the fixed block 12. At this time, the oil can push the movable plate 6 downward, thereby performing an oil cooling operation. After the oil pressure returns to normal, the spring 2 11 rebounds and drives the L-shaped block 10 to move back to its original position, and the elastic telescopic rod 5 rebounds and drives the movable plate 6 to move upward, and 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, and the fixed block 12 continues to push the L-shaped block 10 upward for horizontal movement and compresses the spring 2 11. When the fixed block 12 passes over the inclined surface of the L-shaped block 10, the spring 2 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 are re-engaged to fix the movable plate 6.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
