Embodiment 1
[0042] Embodiment 1, combining Figure 4
[0043] The oil seal assembly 1 is provided with a set of chambers for the installation of the skeleton structure. The skeleton structure is a composite skeleton 3 (which is a hard material such as some plastic parts or metal parts), and the cavity for the composite skeleton 3 to be installed is located in the oil seal assembly 1. It has a groove connecting the upper slope of the lip 102 (the groove here is used for the disassembly and assembly of the composite skeleton 3), thanks to the skeleton structure set in the oil seal assembly 1, when the skeleton structure is the composite skeleton 3, select The annular seal ring 2 is made of rubber of the same material as the oil seal assembly 1. Because the composite skeleton 3 is used as the skeleton structure to provide a relatively stable connection gap, it is suitable for the shaft structure considering the influence of friction.
Embodiment 2
[0044] Embodiment 2, combining Figure 4 , Figure 5 and Image 6
[0045] The oil seal assembly 1 is provided with a group of chambers for the installation of the skeleton structure. The skeleton structure is a spring 14. The chamber for the installation of the spring 14 is located at the bottom end of the oil seal assembly 1, and is provided with a limit spring 14. funnel-shaped stoma (here the stoma structure is used), when the skeleton structure is the spring-4, the lip 102 is displaced in the axial direction under the action of the centripetal elastic force of the spring-4, and the cavity where the composite skeleton 3 is installed The chamber provides an elastic deformation and extension space for the lip 102, and along with the pressure deformation brought by the abutment block 9 at the top of the oil seal assembly 1, the adjustment of the centripetal pressure is realized, which is suitable for the shaft structure that does not need to consider the influence of fricti...
Embodiment 3
[0047] The oil seal assembly (1) is made of a wear-resistant and aging-resistant rubber material, and the rubber material is composed of the following components in parts by weight:
[0048] 100 parts of acrylate rubber, 70 parts of nitrile rubber, 3 parts of silane coupling agent, 2 parts of dicumyl peroxide, 6 parts of nano-silicon carbide, 5 parts of nano-zinc oxide, 5 parts of nano-titanium dioxide, 2 parts of alumina fiber , 3 parts by weight of graphite powder, 1 part of stearic acid, and 1 part of sulfur powder.
[0049] The particle size of the nano-silicon carbide is 30nm, the particle size of the nano-zinc oxide is 40nm, and the particle size of the nano-titanium dioxide is 20nm; the diameter of the alumina fiber is 5um, and the length of the monofilament is 40mm;
[0050] The preparation method of above-mentioned rubber material, comprises the steps:
[0051] 1. 100 parts of acrylate rubber, 70 parts of nitrile rubber, 3 parts of silane coupling agent, 2 parts of d...
