The utility model discloses a high-precision worm and gear speed
reducer, which relates to the technical field of high-precision worm and gear speed reducers, and comprises a bottom shell, an upper shell is fixedly connected to the upper surface of the bottom shell, a filtering mechanism is fixedly connected to the upper surface of the upper shell, the filtering mechanism comprises a filtering box, the bottom surface of the filtering box is fixedly connected with the upper surface of the upper shell, and the bottom surface of the filtering box is fixedly connected with the upper surface of the upper shell. A large
sponge and a small
sponge are clamped to the inner wall of the filter box, a side cover plate is fixedly connected to the back face of the filter box, an
oil pump is fixedly connected to the upper surface of the bottom shell, the input end of the
oil pump penetrates through the bottom shell and extends into the bottom shell, and the output end of the
oil pump fixedly communicates with an oil
pipe. The end, away from the oil pump, of the oil
pipe penetrates through the filter box and extends into the filter box, and a supporting frame is fixedly connected to the upper surface of the filter box. Compared with a traditional speed
reducer, the high-precision worm and gear speed
reducer has the advantages of being time-saving, labor-saving, long in service life, easy to maintain and the like.
