[0002] A speed reducer is a power transmission mechanism that uses gears to reduce the rotational speed of a motor to a desired speed while providing a larger torque. It is an independent, closed transmission device between the prime mover and the driven machine, used to reduce speed and increase torque to meet operational requirements. Speed ​​reducers typically consist of multiple gear pairs; for example, using a small gear to drive a large gear achieves a certain speed reduction. Speed ​​reducers are widely used in modern machinery.

[0003] During operation, existing speed reducers generate a lot of heat due to friction between parts. As the equipment operates for longer, the heat increases. If heat is not dissipated, excessive heat will accumulate inside the speed reducer, leading to overheating. This can damage internal parts and affect the normal operation of the speed reducer. Therefore, a self-protection structure and speed reducer are proposed. Utility Model Content

[0030] Furthermore, a connecting pipe is provided inside one of the first rectangular plates 10, and the interior of the connecting pipe is interconnected with the interior of the water-cooling pipe 3. The first rectangular plate 10 is connected to the upper housing 1 of the reducer by the first bolt. It should be noted that the connecting pipe allows the two water-cooling pipes 3 to be interconnected. Water enters the interior of one water-cooling pipe 3 from the inlet pipe 13, and then enters the interior of the other water-cooling pipe 3 through the connecting pipe, and then is discharged from the outlet pipe 14.

[0031] It should be noted that the external water tank has a water pump installed on top, and a suction pipe is installed at one end of the water pump. The suction pipe is connected to the inlet pipe 13. A drain pipe is installed on the top of the outlet pipe 14 and is connected to the water tank. This allows the cold water in the water tank to circulate through the two water cooling pipes 3 and finally return to the inside of the water tank.

It should be noted that the first metal fin 4 can directly transfer heat to the cold water, and the second metal fin 7 can transfer the heat inside the reducer to the outside of the reducer.

[0033] Furthermore, the top of the box body 5 is connected to the box cover 15 by a second bolt that is evenly distributed. The box cover 15 has evenly distributed ventilation holes.

It should be noted that the servo motor 18 controls the rotation of the cooling fan 6 through the rotating shaft. The cooling fan 6 generates an upward airflow, which can expel the heat inside the reducer upward.

[0036] It should be noted that the specific model and specifications of the servo motor 18 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described. All of them can be powered by external devices and controlled to turn on and off.

[0037] Furthermore, the bottom of the outer wall of the housing 5 is connected to the top of the upper housing 1 of the reducer via the connecting plate 12 and the fourth bolt. The bottom of the housing 5 is in contact with the top of the upper housing 1 of the reducer. A temperature sensor is installed on the top of the upper housing 1 of the reducer. The temperature sensor monitors the operating temperature of the reducer. When the temperature is too high, the cooling fan 6 and cold water circulation are automatically started by the controller and other equipment to dissipate heat and prevent the parts from deforming or being damaged due to overheating. The connection between the fourth bolt, the connecting plate 12 and the upper housing 1 of the reducer is existing technology and will not be described here. The housing 5 can be installed and disassembled.

[0039] Working principle of this utility model:

[0040] First, turn on the servo motor 18. The servo motor 18 will control the rotation of the cooling fan 6 through the rotating shaft. The cooling fan 6 will generate an upward airflow. The airflow can exhaust the heat inside the reducer from the air outlet 17, thereby cooling the inside of the reducer.

[0041] Then, cold water is discharged into one of the water-cooling pipes 3 through external equipment, and then enters the interior of the other water-cooling pipe 3 through the connecting pipe, and is discharged from the outlet pipe 14. The circulating cold water passes through the two water-cooling pipes 3, which can dissipate heat from the inside of the reducer.
