[0034] The embodiment of the present application discloses a sealing structure for the oil inlet and return ports of a chassis of a diesel generator set.

[0035] Reference Figure 1-Figure 2 A sealing structure for the oil inlet and return port of a chassis of a diesel generator set includes a chassis shell 1, and an oil inlet and return port 11 is provided on the chassis shell 1. An oil inlet and return pipe 2 is provided on one side of the chassis shell 1 close to the oil inlet and return port 11, and a flange 3 is provided on the oil inlet and return pipe 2, and a flange seat 4 is provided on the chassis shell 1. A connecting component 5 is provided on the flange 3, and the connecting component 5 connects the flange 3 and the flange seat 4 to the chassis shell 1. In addition, a sealing component 6 is provided between the flange seat 4 and the flange 3, and the sealing component 6 seals the gap between the flange seat 4 and the flange 3.

[0036] The cross-section of the oil inlet and return port 11 on the chassis shell 1 is circular, and a limiting ring 41 is provided on the flange seat 4. One end of the limiting ring 41 is connected to the flange seat 4, and the other end is embedded in the oil inlet and return port 11 of the chassis shell 1, thereby improving the convenience of installing the flange seat 4 on the chassis shell 1.

[0037] In addition, a sealing gasket 42 is provided between the flange seat 4 and the chassis shell 1. When the flange 3 is installed on the chassis shell 1, the sealing gasket 42 is pressed tightly between the chassis shell 1 and the flange seat 4, thereby improving the sealing between the flange seat 4 and the chassis shell 1.

[0038] Furthermore, in order to improve the convenience of installing the flange seat 4 on the chassis shell 1, the connecting component 5 includes a connecting column 51, which is located on the inner side of the chassis shell 1, and four connecting columns 51 are evenly spaced around the axis of the oil return port 11, and the four connecting columns 51 are all welded to the chassis shell 1.

[0039] In addition, a thread groove 511 is provided on one side of the connecting column 51 close to the chassis housing 1, and a connecting bolt 31 is provided on the flange 3, the connecting bolt 31 corresponds to the connecting column 51, and one end of the connecting bolt 31 passes through the flange 3, the flange seat 4 and the chassis housing 1 in sequence, and one end of the connecting bolt 31 passes through the chassis housing 1 and is threadedly engaged with the thread groove 511 on the connecting column 51. This eliminates the need to directly weld the flange seat 4 to the chassis housing 1, so that the flange seat 4 and the flange 3 can be installed on the chassis housing 1 together.

[0040] When the flange 3 is mounted on the flange seat 4 , the oil inlet and return pipes 2 on the flange 3 pass through the oil inlet and return ports 11 on the chassis shell 1 .

[0041] Reference Figure 3-Figure 4 In order to increase the gap between the flange seat 4 and the flange plate 3, the sealing assembly 6 includes a sealing ring 61, which is in an annular shape as a whole and has a circular cross section. In addition, a sealing groove 43 is provided on the side of the flange seat 4 close to the flange plate 3, and the cross section of the sealing groove 43 is circular, and the axis of the sealing groove 43 is coaxial with the axis of the oil inlet and return port 11. When in use, the sealing ring 61 is sleeved in the sealing groove 43.

[0042] Furthermore, a mounting groove 32 is provided on one side of the flange 3 close to the flange seat 4. The cross section of the mounting groove 32 is circular, and the axis of the mounting groove 32 is coaxial with the axis of the sealing groove 43. The sealing assembly 6 also includes a sealing ring 62. The sealing ring 62 is annular in shape as a whole. When in use, the sealing ring 62 is sleeved in the sealing groove 43. The gap between the flange 3 and the flange seat 4 is sealed by the sealing ring 62 and the sealing ring 61.

[0043] In order to further improve the sealing performance between the flange seat 4 and the flange 3, a sealing protrusion 63 is formed on the sealing ring 62, and one side of the sealing protrusion 63 is integrally formed with the sealing ring 62. When the flange 3 is installed on the flange seat 4, the sealing protrusion 63 is pressed against the sealing ring 62. In addition, a supporting inclined surface 44 is formed on one side of the flange seat 4 close to the sealing groove 43, and an extrusion surface 64 is formed on the sealing protrusion 63. When the flange 3 is connected to the flange seat 4, the extrusion surface 64 on the sealing protrusion 63 on the sealing ring 62 is pressed against the supporting inclined surface 44 on the flange seat 4. As the flange 3 is installed on the flange seat 4, the sealing protrusion 63 on the sealing ring 62 is pressed against the sealing ring 62.

[0044] The implementation principle of the sealing structure at the oil inlet and return port of the chassis of a diesel generator set in an embodiment of the present application is: the connecting bolt 31 passes through the flange 3, the flange seat 4 and the chassis shell 1 in sequence, and then the connecting bolt 31 passes through one end of the chassis shell 1 and is threadedly engaged with the threaded groove 511 on the connecting column 51. As the flange 3 is pressed against the flange seat 4, the sealing ring 62 on the flange 3 is pressed against the sealing ring 61 of the flange seat 4.
