Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
referring to fig. 1 to 6, a combined sealing ring includes a first sealing ring, a supporting ring 2, and a second sealing ring 3, which are used together;
the first sealing ring comprises three structures of a supporting sealing surface 4, an oil through groove 5 and a mounting groove 6;
the supporting sealing surface is designed along the upper part of the sealing section, the radial width is designed according to the width of the supporting surface of the mounting structure, and a transition bevel edge is arranged between the supporting sealing surface and the oil through groove;
the oil through groove is lower than the supporting sealing surface at the left side position, and a transition bevel edge is arranged between the oil through groove and the supporting sealing surface to ensure that a radial release space is reserved in the compression process of the supporting sealing surface;
the mounting groove is designed according to the size of the supporting shoulder in the groove width and the depth, and the root of the groove is designed with a fillet to prevent the sealing ring from being torn from the root.
The first sealing ring is made of rubber materials and can meet the requirements of temperature and cooling media.
The support ring comprises four structures of a first mounting bulge 7, a mounting concave table 8, an oil through hole 9 and a second mounting bulge 10;
the mounting bulge is triangular, and the bulge ensures that a certain interference magnitude is increased after the sealing ring is mounted and is not easy to fall off;
the mounting concave table is smaller than the whole thickness of the support ring, and can be adaptively designed according to the specific structural size, so that the mounting and sealing effects of the sealing ring are ensured;
the oil through holes are uniform small holes which are uniformly distributed along the circumference, the diameter of each small hole determines the oil through flow, and the axial position of each small hole influences the heat dissipation efficiency;
the support ring is made of high polymer materials and has the characteristics of high temperature resistance and high strength.
The second sealing ring comprises three structures, namely an arc shoulder 11, a supporting boss 12 and a mounting groove 13;
the whole shape of the circular arc convex shoulder is triangular, the root of the triangle is jointed with a rectangular surface at the right end of the sealing ring, the left part of the circular arc convex shoulder is in inverted transition, the circular arc forms a sealing surface to be in contact with an external structure and to be compressed, and the triangular supporting surface ensures that the sealing surface has a radial release space in the compression process;
the supporting boss ensures that the sealing ring and the mounting structure are in interference fit and are not easy to fall off, and meanwhile, the support of the boss also ensures that a gap is reserved between the whole sealing surface and the structure along the circumferential direction, so that the smooth circulation of cooling oil is ensured;
the mounting groove, its groove width and degree of depth design according to the size of supporting the convex shoulder, and the design of groove root has the fillet, prevents that the sealing washer from tearing from the root.
The second sealing ring is made of rubber materials and can meet the requirements of temperature and cooling media.
