[0020] A helical gear prefix reducer includes a reducer housing 1, a built-in groove 2 is provided inside the reducer housing 1, reserved supports 3 are respectively provided at the front and rear ends of the built-in groove 2, a magnetic filter 6 is provided between a group of reserved supports 3, and a clamping block 5 is fixedly connected to the front and rear ends of the magnetic filter 6. The magnetic filter 6 is fixedly connected to a threaded clamping seat 7 near the edge of the reducer housing 1, and a magnetic rod 8 is threadedly connected to the bottom of the threaded clamping seat 7. An oil drain pipe port 4 is connected to the lower position of one side of the reducer housing 1, a notch 9 is provided on the top surface of the clamping block 5, and a slide groove 11 is connected to the bottom of the notch 9. A slider 12 is slidably connected to the inside of the slide groove 11, and a push block 10 is fixedly connected to the top of the slider 12.

[0021] like Figure 1 As shown, a drive shaft 15 is provided at the front end of the reducer housing 1, and an adapter card seat 17 is fixedly connected to the right side of the reducer housing 1. A drive motor 16 is fixedly installed on the side of the adapter card seat 17 away from the reducer housing 1, and the output end of the drive motor 16 passes through the adapter card seat 17 and extends to the interior of the reducer housing 1. The arrangement of the output end of the drive motor 16 extending to the interior of the reducer housing 1 will facilitate the subsequent relative rotation of the drive motor 16 with the gear assembly inside the reducer housing 1.

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the top of the reserved support platform 3 is provided with a card slot that is engaged with the card block 5, and the reserved support platform 3 and the protruding end of the push block 10 are engaged and connected. This arrangement will facilitate the reserved support platform 3 to be able to realize the engagement connection with the elastic buckle composed of the card block 5, the notch 9, the push block 10, the slide groove 11, the slider 12, the guide rod 13 and the spring 14; the outer shape of the push block 10 is an "L"-shaped structure, and the push block 10 is slidably connected to the card block 5 through the slider 12, the slide groove 11, and the card block 5. The guide rod 13 is inserted into the inner side of the slider 12, and the guide rod 13 and the card block 5 are fixedly connected. The outer sleeve of the guide rod 13 is provided with a spring 14, and the spring 14 is fixedly connected to the slider 12 and the card block 5 respectively. When pushing a The push block 10 is assembled so that it can be separated from the reserved support platform 3. At the same time, the magnetic filtering structure can be easily disassembled by simply taking out a group of card blocks 5 at the same time; the magnetic rods 8 are arranged in a vertical structure toward the depth of the built-in groove 2, and the magnetic rods 8 and the magnetic filter 6 are adjacent to each other on the left and right. The size of the magnetic filter 6 is consistent with the gap size formed by a group of reserved support platforms 3. The position of the magnetic filter 6 relative to the oil drain pipe port 4 is vertically arranged on the inner side of the built-in groove 2. After the magnetic filter 6 first magnetically filters the metal debris in the lubricating oil, multiple magnetic rods 8 will also perform secondary magnetic adsorption treatment on the metal debris, thereby improving the overall magnetic filtering effect.

[0023] Working process: The electric energy required for the startup and operation of the device in the present invention all comes from an external power supply. When using the helical gear prefix reducer, first, the drive shaft 15 is stably connected to the drive member by keying, and the drive motor 16 in the helical gear prefix reducer will start to rotate the gear assembly provided inside the reducer housing 1, and generate a relative driving force, thereby providing a more powerful transmission force to the drive member to carry out machining operations. When the adjacent gears wear each other during rotation, and some metal debris falls into the reducer housing 1, first of all, it is considered that the lubricating oil inside the reducer housing 1 will shake due to the rotation of the gears, so that the magnetic filter 6 installed inside the built-in groove 2 can magnetically absorb the metal debris mixed in the lubricating oil, and at the same time, When it is necessary to discharge and replace the lubricating oil inside the reducer housing 1, the oil inlet pipe of the external water pump is quickly connected to the oil discharge pipe port 4, and the lubricating oil inside the reducer housing 1 is gradually drawn out after starting. In the process of gradually converging the lubricating oil inside the reducer housing 1 toward the inner side of the built-in groove 2, under the elastic snap-fit limitation composed of the block 5, notch 9, push block 10, slide 11, slider 12, guide rod 13 and spring 14, the entire helical gear prefix reducer will pass through the magnetic filter 6 and the magnetic rod 8 to magnetically filter the lubricating oil flowing out in one direction, thereby achieving the purpose of filtering and removing impurities of metal debris. Subsequently, it is only necessary to quickly disassemble and assemble the magnetic filter structure to conveniently centrally process the magnetically attracted metal debris, thereby reducing the retention of metal debris inside the reducer housing 1.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
