The liquid storage chamber 10 is connected with the shell 1 through a one-way liquid outlet valve 11. The one-way liquid outlet valve 11 is arranged near the front and rear inner walls of the bottom box 6 for refrigeration. A filter screen 12 is arranged in the liquid storage chamber 10. The liquid storage chamber 10 is connected with the upper side of the shell 1 through an extraction mechanism 13. The extraction mechanism 13 is installed in the installation chamber 9. Semiconductor refrigeration plates 16 are arranged on the front and rear side walls of the bottom box 6 corresponding to the liquid storage chamber 10. Heat dissipation fins are arranged on the sides of the semiconductor refrigeration plates 16 facing outward to meet the heat exchange requirements.

[0020] Specifically, the locking mechanism 7 includes a fixing block 701 and a locking bolt 702. The front and rear sides of the shell 1 and the upper surface of the bottom box 6 are both rectangularly fixed with fixing blocks 701, and the upper and lower corresponding fixing blocks 701 are locked and fixed by locking bolts 702.

[0021] In this embodiment, the locking bolts 702 lock and fix the corresponding upper and lower fixing blocks 701 to achieve the effect of locking and fixing the shell 1 and the bottom box 6. The rubber shock-absorbing pad 5 sandwiched between the upper and lower fixing blocks 701 provides a buffering and shock-absorbing effect.

[0022] Specifically, a slag discharge valve 14 is installed at the lower side of the right side wall of the bottom box 6 corresponding to the liquid storage chamber 10 .

[0023] In this embodiment, the slag discharge valve 14 can discharge the lubricating oil containing more impurities from the bottom box 6, so as to facilitate the replacement of the lubricating oil.

[0024] Specifically, the filter screen plate 12 is installed between the inner walls of the liquid storage chamber 10 in an inclined state, and the inclination angle of the filter screen plate 12 is 45-60 degrees.

[0025] In this embodiment, the filter screen 12 filters impurities in the lubricating oil, and the impurities are not easily adhered to the filter screen 12 .

[0027] In this embodiment, the temperature sensor 133 detects the temperature of the lubricating oil in the shell 1. When the temperature is greater than the set value, the information is fed back to the controller 134. The controller 134 enables the semiconductor refrigeration plate 16 to cool the lubricating oil in the bottom box 6. The controller 134 enables the extraction component 131 to draw the lubricating oil in the bottom box 6 into the liquid distribution pipe 132, and then the lubricating oil flows evenly on the worm assembly 3 through the liquid distribution pipe 132. At the same time, the high-temperature lubricating oil in the shell 1 flows into the bottom box 6 through the one-way liquid outlet valve 11.

[0030] When in use, the rubber shock-absorbing pad 5 is used to increase the buffering and shock-absorbing function of the bottom of the shell 1, and the sound insulation board 4 is used to increase the sound insulation function of the inner wall of the shell 1, so that the noise of the worm gear reducer is greatly reduced, and the temperature of the lubricating oil in the shell 1 is detected by the temperature sensor 133 in the extraction mechanism 13. When the temperature is greater than the set value, the information is fed back to the controller 134. The controller 134 enables the semiconductor refrigeration plate 16 to cool the lubricating oil in the bottom box 6. The controller 134 enables the extraction component 131 to draw the lubricating oil in the bottom box 6 into the liquid distribution pipe 132, and then the liquid distribution pipe 132 flows evenly on the worm component 3. At the same time, the high-temperature lubricating oil in the shell 1 flows into the bottom box 6 through the one-way liquid outlet valve 11, and the filter plate 12 filters the impurities in the lubricating oil in the bottom box 6. This cycle achieves the effect of cooling and removing impurities of the lubricating oil, so that the lubricating oil can better lubricate the worm gear, reduce friction loss or noise, and extend the service life of the worm gear reducer.

[0031] In summary, the low-noise worm gear reducer increases the buffering and shock-absorbing function of the bottom of the housing 1 and increases the sound insulation function of the inner wall of the housing 1, so that the noise of the worm gear reducer is greatly reduced. During use, the lubricating oil can be cooled and impurities in the lubricating oil can be filtered, so that the lubricating oil can better lubricate the worm gear, reduce friction loss or noise, and extend the service life of the worm gear reducer.
