Abstract
Description
Technical Field
[0001] This utility model relates to the field of speed reducer equipment technology, specifically a speed reducer with a cooling structure. Background Technology
[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine. Its function is to increase torque by reducing the speed, thereby meeting the power requirements of different working machines. At the same time, it can also change the transmission direction to a certain extent, making the power transmission more rational and efficient.
[0003] Speed reducers can reduce speed, increase torque, change rotation direction, and achieve overload protection and reversing functions. They can also save space, reduce costs, and improve the mechanical performance of equipment. However, existing speed reducers use natural heat dissipation or simple heat dissipation fin structures, which have a relatively slow heat dissipation speed. Moreover, most heat dissipation structures are fixed, making it difficult to quickly disassemble, install, maintain, and replace them. Utility Model Content
[0004] The purpose of this invention is to provide a reducer with a cooling structure to address the problem that existing reducers use natural heat dissipation or simple heat dissipation fin structures, resulting in slow heat dissipation and that most heat dissipation structures are fixed, making quick disassembly, maintenance, and replacement difficult.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reducer with a cooling structure, comprising: a reducer housing, an elastic heat sink movably inserted inside the reducer housing, a cooling hose fixedly connected to the inner side of the elastic heat sink, a heat dissipation connecting strip movably snapped onto one end of the top of the reducer housing, a cooling mechanism provided at the other end of the top of the reducer housing, a docking short pipe provided at one end of the bottom of the cooling mechanism, and a connecting mechanism provided at one end of the top of the cooling hose.

The elastic heat sink and the cooling hose are both adapted to the U-shaped receiving cavity, and the heat dissipation connecting strip is adapted to the slot.
[0007] As a further embodiment of this utility model: a cooling tank, a circulating pump, and a condenser; the cooling tank is fixedly connected to the other end of the top of the reducer housing; the circulating pump is fixedly connected to the top of the cooling tank via a pipe; the condenser is fixedly connected to the other end of the top of the reducer housing; the cooling tank and the circulating pump are connected via a pipe; a first diverter, an outlet pipe, a second diverter, and an inlet pipe; the first diverter is fixedly connected to the outlet of the circulating pump; the outlet pipe is rotatably connected to one end of the first diverter; the second diverter is fixedly connected to the inlet of the condenser; the inlet pipe is rotatably connected to one end of the second diverter; multiple sets of short connecting pipes are symmetrically fixedly connected to the bottom of the outlet pipe and the inlet pipe.
[0008] As a further embodiment of this utility model: the connecting mechanism includes a telescopic tube, an internally threaded connecting tube, and a polygonal rotating component. The telescopic tube is fixedly connected to the bottom of the docking short tube, the internally threaded connecting tube is rotatably connected to the bottom of the telescopic tube, the polygonal rotating component is fixedly connected to the outside of the internally threaded connecting tube, and the internally threaded connecting tube is threadedly connected to the cooling hose.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, a circulating pump draws coolant from the cooling tank, which flows through a first diverter joint, an outlet pipe, and a connecting short pipe. Then, it passes through a telescopic pipe and an internally threaded connecting pipe into a cooling hose. After absorbing heat from inside the reducer housing, the coolant flows out through the telescopic pipe, then through another set of telescopic pipes, internally threaded connecting pipes, a connecting short pipe, an inlet pipe, and a second diverter joint back to the condenser. There, it exchanges heat with the outside air, cools down, and then returns to the cooling tank, completing the circulation. Straight and flexible heat sinks assist in heat dissipation. This combined active cooling method is more efficient than traditional natural or simple cooling structures, and can quickly reduce the internal temperature of the reducer. To avoid performance degradation and component damage, ensuring efficient operation, the flexible heat sink is inserted into the U-shaped receiving cavity and brought in using its connection with the cooling hose, exposing both ends. The heat dissipation connecting strip is then inserted into the slot and limited. The telescopic tube at the bottom of the connecting short tube is pulled down, allowing the internal threaded connecting tube to align with the cooling hose port. The multi-sided rotating threaded connection is then rotated. This design allows for quick disassembly and assembly, facilitating maintenance and replacement, reducing time and costs, and improving equipment efficiency. The first and second rotating joints facilitate rotating the outlet and inlet pipes during disassembly and assembly, avoiding obstruction, providing operating space, and enhancing installation and maintenance convenience.

[0021] Reference Figures 1 to 6 In this embodiment of the present invention, a reducer with a cooling structure includes: a reducer housing 1, which serves as the main frame of the entire reducer and provides installation space for heat dissipation components; an elastic heat sink 2 is movably inserted into the reducer housing 1; a cooling hose 3 is fixedly connected to the inner side of the elastic heat sink 2; and a heat dissipation connecting strip 4 is movably snapped onto one end of the top of the reducer housing 1. The elastic heat sink 2 is inserted into the reducer housing 1 and then snapped into the heat dissipation connecting strip 4 through the top of the reducer housing 1, so that the internal heat is transferred to the heat dissipation connecting strip 4 through the elastic heat sink 2 for auxiliary heat dissipation; and the cooling hose 3 can be filled with coolant to circulate and cool the inside of the reducer housing 1. The other end of the top of the reducer housing 1 is provided with a cooling mechanism 5. One end of the bottom of the cooling mechanism 5 is provided with a docking short pipe 6. One end of the top of the cooling hose 3 is provided with a connecting mechanism 7. The cooling hose 3 is connected to the connecting mechanism 7 through the docking short pipe 6. Then the cooling mechanism 5 is started to circulate heat dissipation. The heat dissipation connecting straight plate 4 is movably inserted into the elastic heat sink 2. There are multiple sets of heat dissipation connecting straight plate 4, elastic heat sink 2 and cooling hose 3. There are multiple sets of connecting mechanisms 7, which are symmetrically arranged at both ends of the top of the multiple sets of cooling hose 3.
[0022] Reference Figure 1 and Figure 2The reducer housing 1 has a U-shaped cavity 8 inside to accommodate the elastic heat sink 2 and the cooling hose 3. The other end of the top of the reducer housing 1 has a slot 9 for inserting the heat dissipation connecting strip 4. The elastic heat sink 2 and the cooling hose 3 are both adapted to the U-shaped cavity 8, and the heat dissipation connecting strip 4 is adapted to the slot 9.
[0023] Reference Figure 1 , Figure 4 and Figure 5 The system includes a cooling tank 501, a circulating pump 502, and a condenser 503. The cooling tank 501 is fixedly connected to the other end of the top of the reducer housing 1. The circulating pump 502 is fixedly connected to the top of the cooling tank 501 via a pipe. The condenser 503 is fixedly connected to the other end of the top of the reducer housing 1. The cooling tank 501 and the circulating pump 502 are connected by a pipe. The system also includes a first diverter 504, an outlet pipe 505, a second diverter 506, and an inlet pipe 507. The first diverter 504 is fixedly connected to the outlet of the circulating pump 502. The outlet pipe 505 is rotatably connected to one end of the first diverter 504. The second diverter 506 is fixedly connected to the inlet of the condenser 503. The inlet pipe 507 is rotatably connected to one end of the second diverter 506. A short pipe 6 is connected to the condenser housing 1. Multiple sets of cooling systems are symmetrically and fixedly connected to the bottom of the outlet pipe 505 and the inlet pipe 507. The circulating pump 502 draws out the coolant from the cooling tank 501 and delivers it to the docking short pipe 6 through the first diverter 504 and the outlet pipe 505. The coolant then enters the cooling hose 3 through the connecting mechanism 7 to absorb the heat generated inside the reducer housing 1. It then flows out through the other end of the cooling hose 3, passes through another set of connecting mechanisms 7, the docking short pipe 6, the inlet pipe 507, and the second diverter 506, and returns to the condenser 503. In the condenser 503, the coolant exchanges heat with the outside air, and the heat of the coolant is dissipated into the air, reducing the coolant temperature. It then returns to the cooling tank 501, completing one cooling cycle.
[0024] Reference Figure 1 and Figure 6The connecting mechanism 7 includes a telescopic tube 701, an internally threaded connecting tube 702, and a polygonal rotating part 703. The telescopic tube 701 is fixedly connected to the bottom of the connecting short tube 6. The internally threaded connecting tube 702 is rotatably connected to the bottom of the telescopic tube 701. The polygonal rotating part 703 is fixedly connected to the outside of the internally threaded connecting tube 702. The internally threaded connecting tube 702 is threadedly connected to the cooling hose 3. When the elastic heat sink 2 is inserted into the U-shaped receiving cavity 8, due to the connection relationship between the cooling hose 3 and the elastic heat sink 2, it can be brought into the U-shaped receiving cavity 8 until... Both ends of the flexible heat sink 2 and both ends of the cooling hose 3 are exposed from the reducer housing 1. Then, the heat dissipation connecting strip 4 is inserted into the slot 9, and at the same time, it limits the heat dissipation connecting strip 4. Then, pull down the telescopic tube 701 at the bottom of the docking short tube 6 so that the internal thread connecting tube 702 is docked with the port of the cooling hose 3. Then, use a tool to rotate the polygonal rotating part 703 so that the internal thread connecting tube 702 is threadedly connected to the cooling hose 3. In this way, the installation of the flexible heat sink 2, the cooling hose 3 and the heat dissipation connecting strip 4 is completed.
[0025] The working principle of this utility model is as follows: Step 1, during use, the coolant in the cooling tank 501 is drawn out by the circulating pump 502 and transported to the docking short pipe 6 through the first diverter 504 and the outlet pipe 505. The coolant then passes through the telescopic pipe 701 and the internal threaded connecting pipe 702 in sequence into the cooling hose 3, where it absorbs the heat generated inside the reducer housing 1. Then, it flows out through the other end of the cooling hose 3, passes through another set of telescopic pipes 701, internal threaded connecting pipes 702, the docking short pipe 6, the inlet pipe 507, and the second diverter 506, and returns to the condenser 503. In the condenser 503, the coolant... The coolant exchanges heat with the outside air, dissipating its heat into the air and lowering its temperature. It then returns to the cooling tank 501, completing one cooling cycle. Furthermore, the design of the heat dissipation connection fins 4 and elastic heat sinks 2 further carries away heat, enhancing the cooling effect. These two elements work together to ensure the reducer's cooling performance, allowing it to operate efficiently in a suitable temperature environment. Compared to traditional natural cooling or simple cooling structures, this combined active cooling method reduces the internal temperature of the reducer more quickly and efficiently, ensuring it operates at a suitable temperature. To prevent performance degradation and component damage due to overheating during operation in a controlled temperature environment; Step two, during installation, insert the elastic heat sink 2 into the U-shaped receiving cavity 8. Due to the connection between the cooling hose 3 and the elastic heat sink 2, it can be pushed into the U-shaped receiving cavity 8 until both ends of the elastic heat sink 2 and both ends of the cooling hose 3 protrude from the reducer housing 1. Then, insert the heat dissipation connecting strip 4 into the slot 9, while limiting its position. Then, pull down the telescopic tube 701 at the bottom of the docking short tube 6 to align the internal threaded connecting tube 702 with the port of the cooling hose 3, and use tools... Rotating the polygonal connector 703 allows the internal threaded connecting pipe 702 to be threadedly connected to the cooling hose 3, thus completing the installation of the elastic heat sink 2, cooling hose 3, and heat dissipation connecting strip 4. This enables quick assembly and disassembly, facilitating maintenance and replacement, reducing maintenance time and costs, and improving equipment efficiency. The design of the first and second swivel joints 504 and 506 allows for rotation of the outlet pipe 505 and inlet pipe 507 during assembly and disassembly, preventing obstruction of installation and disassembly and providing greater operating space for installation and disassembly, further improving the convenience of installation and maintenance.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
