In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] Figure 1 This is a schematic diagram of the installation of the built-in oil retaining ring structure in the utility model; Figure 2 It is a structural schematic diagram of the oil retaining ring in the utility model; Figure 3 yes Figure 2 For the cross-sectional view in the AA direction, see Figures 1 to 3 As shown, a preferred embodiment is shown, which shows a built-in oil retaining ring structure, including an oil retaining ring 1, an oil seal 2, a reducer housing 3, a mounting flange 4 and a large gear 5. The reducer housing 3 is provided with a large gear 5 inside, the mounting flange 4 passes through the reducer housing 3 and is connected to the large gear 5, an oil seal 2 is provided between the mounting flange 4 and the reducer housing 3, an oil retaining ring 1 is provided on the inner wall of the reducer housing 3, the oil retaining ring 1 presses the oil seal 2, and fixes the oil seal 2 between the mounting flange 4 and the reducer housing 3. In this embodiment, see Figure 1 As shown, the oil retaining ring 1 is arranged inside the reducer housing 3, adopting a built-in arrangement, and in combination with an oil seal 2, it can adapt to the installation environment where the reducer structure is limited and the sealing requirements are strict. Among them, an annular protrusion structure is provided on the inner wall of the reducer housing 3, and a gap is provided between the protrusion structure and the mounting flange 4 for installing the oil seal 2. The oil retaining ring 1 is arranged at the upper end of the protrusion structure, and the lower surface of the oil retaining ring 1 contacts the oil seal 2 to fix the position of the oil seal 2, and the two sides of the oil seal 2 contact the protrusion structure and the mounting flange 4 to achieve sealing between the two.
[0022] Further, as a preferred embodiment, the oil deflector 1 includes a mounting plate 6 and an oil deflector 7 disposed at one end of the mounting plate 6. The longitudinal section of one side of the oil deflector 1 is L-shaped. The mounting plate 6 and the oil deflector 7 are welded and connected to the inner wall of the reducer housing 3 by bolts 8. For details, see Figure 1 As shown, the mounting plate 6 is fixed at the upper end of the raised structure, and the mounting plate 6 presses down the oil seal 2 so that the position of the oil seal 2 is fixed, and the oil retaining ring 7 is against the mounting flange 4 and the large gear 5 to block the oil, so that the lubricating oil thrown up by the large gear 5 can return to the reducer housing 3, and only a very small amount of lubricating oil reaches the lip of the oil seal 2, thereby reducing the impact of the lubricating oil on the lip of the oil seal 2, thereby ensuring the effectiveness of the oil seal 2 and improving the sealing requirements of the reducer.

It also includes a screw 10, and the screw 10 connects the mounting flange 4 and the large gear 5. The positioning between the large gear 5 and the mounting flange 4 is achieved by the positioning pin 9, and then the mounting flange 4 and the large gear 5 are connected together by the screw 10, and when the large gear 5 rotates, the mounting flange 4 can be driven to rotate.
[0024] When in use, the large gear 5 rotates to throw up the lubricating oil in the reducer housing 3, and most of the thrown up lubricating oil will be blocked by the oil retaining ring 7 in the oil retaining ring 1, so that the lubricating oil returns to the reducer housing 3.
[0025] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
