Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically a torque amplification power take-off housing with a cooling mechanism. Background Technology

[0002] In modern engineering and mechanical applications, torque-amplified power take-offs (PTOs) play a crucial role. During operation, numerous internal mechanical components interact, such as gear meshing and shaft rotation. These processes inevitably generate friction, resulting in a significant amount of heat. Traditional PTO housings often lack effective heat dissipation methods. Under prolonged or high-load operation, the internal temperature of the housing can rise sharply. Excessive temperature can degrade the performance of the lubricating oil inside the PTO, reducing lubrication effectiveness and thus exacerbating wear between components, shortening the lifespan of the PTO. Furthermore, high temperatures can affect the precision of the fitting of internal components, reducing transmission efficiency and even causing malfunctions, thus impacting the normal operation of the entire equipment. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a torque amplification power take-off housing with a cooling mechanism, which solves the problem that traditional power take-off housings often lack effective heat dissipation methods. Under long-term or high-load working conditions, the internal temperature of the housing will rise sharply, which may lead to a decrease in the performance of the lubricating oil inside the power take-off, reduce the lubrication effect, and thus aggravate the wear between components. Moreover, high temperature may also affect the fitting accuracy of precision components inside the power take-off, reduce transmission efficiency, and affect the normal operation of the entire equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a torque amplification power take-off housing with a cooling mechanism, comprising a housing, two cooling mechanisms respectively provided on both sides of the housing, each cooling mechanism including a fixed bracket, a plurality of heat dissipation fins fixedly installed between the inner walls of the fixed bracket, the heat dissipation fins being in contact with the housing, a connecting pipe provided inside the fixed bracket, the connecting pipe passing through the plurality of heat dissipation fins and having a bent and inserted design, a plurality of fixing protrusions fixedly installed on the outer wall of the fixed bracket, a fixing bolt provided on one side of each fixing protrusion, the fixing bolt passing through the fixing protrusion, the fixed bracket being fixedly installed on one side of the housing by the fixing bolt, and the fixing bolt being threadedly connected to the side of the housing.

[0005] As a further embodiment of this utility model: a circulation mechanism is provided on one side of the housing, the circulation mechanism includes a liquid storage tank, an injection port is provided at the top of the liquid storage tank at its center, and an outlet is provided at the bottom of the liquid storage tank near its side.

[0006] As a further embodiment of this utility model: a suction pump is fixedly installed on one side of the liquid storage tank, and two infusion pipes are fixedly connected to the output ends on both sides of the suction pump.

[0007] As a further embodiment of this utility model: two return pipes are fixedly connected to both sides of the liquid storage tank, and both the infusion pipe and the return pipe are flexible tubes.

[0008] As a further embodiment of this utility model: connectors are fixedly installed at both ends of the connecting tube, the output ends of the infusion tube and the return tube, and the connectors at both ends of the connecting tube correspond to the connectors at the ends of the infusion tube and the return tube, respectively.

[0009] As a further embodiment of this utility model: two connecting bolts are symmetrically distributed on one side of the connector, and the connecting bolts pass through the two corresponding connectors and are threaded to them.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The torque amplification power take-off housing with a cooling mechanism transfers the heat generated by the power take-off during operation to the housing, which then transfers the heat to the heat dissipation fins. A suction pump delivers coolant from the storage tank to the connecting pipe via a delivery pipe. The coolant in the connecting pipe absorbs the heat absorbed by the heat dissipation fins. In this way, the internal temperature of the power take-off is effectively prevented from becoming too high due to prolonged operation or high load, keeping the operating temperature of the power take-off relatively stable and thus improving the overall working stability of the power take-off.

[0012] 2. The torque amplification power take-off housing with cooling mechanism has a circulation mechanism. When the power take-off is used, the suction pump draws coolant from the storage tank and delivers the coolant to the connecting pipe through the delivery pipe. The coolant flows in the connecting pipe, carrying away the heat from the heat dissipation fins, and then flows back into the storage tank through the return pipe. Through this circulation, the coolant can repeatedly participate in the heat exchange process, achieving efficient heat transfer and enabling the heat inside the power take-off to dissipate quickly, thus improving the heat dissipation efficiency of the housing during cooling.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a torque amplifying power take-off (PTO) housing with a cooling mechanism, comprising a housing 1, with two cooling mechanisms 2 respectively provided on both sides of the housing 1. Each cooling mechanism 2 includes a fixed bracket 201, with several heat dissipation fins 202 fixedly installed between the inner walls of the fixed bracket 201. The heat dissipation fins 202 are in contact with the housing 1. Because of the heat dissipation fins 202, the heat dissipation area is increased, allowing the heat from the housing 1 to dissipate more quickly, effectively reducing the temperature of the housing 1, preventing the performance of the PTO from being affected by excessive temperature, and improving the stability and reliability of the PTO's operation. A connecting pipe 203 is provided inside the fixed bracket 201, through which several heat dissipation fins 202 are passed, and the connecting pipe 203 has a bent and interlocking design. This design of the connecting pipe 203 allows the cooling fins to pass through. When the coolant flows in the connecting pipe 203, it fully exchanges heat with the heat dissipation fins 202, improving heat dissipation efficiency and allowing heat to be carried away more efficiently, further optimizing the cooling effect. Several fixing protrusions 3 are fixedly installed on the outer wall of the fixing bracket 201. Each fixing protrusion 3 has a fixing bolt 4 on one side. The fixing bolt 4 passes through the fixing protrusion 3. The fixing bracket 201 is fixedly installed on one side of the housing 1 by the fixing bolt 4, and the fixing bolt 4 is threaded to the side of the housing 1. This fixing method is not only firm and reliable, ensuring that the cooling mechanism 2 will not loosen due to vibration or other reasons during the operation of the power take-off, but also ensures that the cooling mechanism 2 continues to play a stable role. At the same time, the cooling mechanism 2 can be removed by unscrewing the fixing bolt 4, so that the heat dissipation fins 202 can be cleaned and replaced, improving the efficiency of subsequent maintenance.

[0021] A circulation mechanism 5 is provided on one side of the housing 1. The circulation mechanism 5 includes a liquid storage tank 501. An inlet 502 is opened at the center of the top of the liquid storage tank 501, and an outlet 503 is opened at the bottom of the liquid storage tank 501 near its side. A suction pump 504 is fixedly installed on one side of the liquid storage tank 501. Two delivery pipes 505 are fixedly connected to the output ends of the suction pump 504 on both sides. Through the cooperation between the suction pump 504, the delivery pipes 505 and the return pipe 506, the suction pump 504 delivers the coolant in the liquid storage tank 501 to the connecting pipe 203 through the delivery pipes 505, and then delivers it back to the liquid storage tank 501 through the return pipe 506 connected to the other end of the connecting pipe 203. This allows the coolant to circulate and remove heat from the housing 1, improving the cooling effect. To improve the heat dissipation effect of the cooling mechanism 2, two return pipes 506 are fixedly connected to both sides of the liquid storage tank 501. Both the infusion pipe 505 and the return pipe 506 are flexible tubes. Connectors 6 are fixedly installed at both ends of the connecting pipe 203 and at the output ends of the infusion pipe 505 and the return pipe 506. The connectors 6 at both ends of the connecting pipe 203 correspond to the connectors 6 at the ends of the infusion pipe 505 and the return pipe 506, respectively. Two connecting bolts 7 are symmetrically distributed on one side of the connector 6. The connecting bolts 7 pass through the corresponding two connectors 6 and are threaded to them. This threaded connection makes the connection between the connectors 6 firm and easy to disassemble and install. By unscrewing the connecting bolts 7 and then unscrewing the fixing bolts 4, it is convenient to remove the cooling mechanism 2 for inspection and maintenance.

[0022] The working principle of this utility model is as follows: During the use of the power take-off, the heat emitted by it is transferred to the housing 1. Since the heat dissipation fins 202 in the cooling mechanism 2 are in contact with the housing 1, the heat dissipation fins 202 can receive the heat from the housing 1. At the same time, the suction pump 504 in the circulation mechanism 5 works to extract the coolant from the storage tank 501 and transport it through the liquid delivery pipes 505 at both output ends. The coolant reaches the connectors 6 at both ends of the connecting pipe 203 through the liquid delivery pipes 505. Since the connecting bolts 7 pass through the corresponding connectors 6 to ensure a firm connection, the coolant can enter the connecting pipe 203. The connecting pipe 203 has a bent and inserted design. When the coolant flows in it, it fully exchanges heat with the heat dissipation fins 202 and takes away the heat absorbed by the heat dissipation fins 202 from the housing 1. Then, the coolant flows back to the storage tank 501 through the return pipe 506 connected to the other end of the connecting pipe 203 under the action of the suction pump 504. This cycle is repeated to achieve cooling of the housing 1.
