Preferably, the outer end face of the oil seal rubber body is provided with an annular deformation groove.
Preferably, the upper part and the lower part of the oil seal rubber body where the concave sealing surface is located are a main sealing lip and an auxiliary sealing lip respectively;
the inner edge of the metal shaping framework is provided with a plurality of uniformly arranged clip-shaped elastic sheets, the cross sections of the clip-shaped elastic sheets are matched with the concave sealing surface, and the upper ends and the lower ends of the clip-shaped elastic sheets are respectively positioned at the main sealing lip and the auxiliary sealing lip;
the outer edge of metal design skeleton is provided with a plurality of design shell fragments of evenly arranging, and the design shell fragment sets up in the inboard oil blanket rubber body of outsourcing skeleton.
Preferably, the upper end face and the lower end face of the outer wrapping framework are both hidden in the oil seal rubber body.
Preferably, the metal shaping framework, the clip-shaped spring plate and the shaping spring plate are all made of thin-wall materials, and the metal shaping framework is provided with a plurality of lightening holes.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. compared with the rubber inner-wrapped framework oil seal on the market, the rubber inner-wrapped framework oil seal is good in strength, high in hardness, more convenient to assemble and capable of completely avoiding the situation that the oil seal generates trimming in the assembling process;
2. the corrosion resistance of the material is very good, and the corrosion resistance of the outboard engine in seawater for a long time is ensured to reach the optimal state.
Description of the drawings:
fig. 1 is a schematic cross-sectional structure of the present invention;
fig. 2 is a schematic view of the top view structure of the metal shaped frame, the clip and the shaped clip of the present invention;
fig. 3 is a schematic view of the enlarged partial structure of fig. 1 according to the present invention;
fig. 4 is a schematic bottom view of the present invention.
The specific implementation mode is as follows:
the invention will be described in further detail by way of example with reference to the accompanying drawings:
an oil seal for outboard machines comprises an annular oil seal rubber body 1, wherein the annular inner wall of the oil seal rubber body 1 is provided with a concave sealing surface, the outer wall of the oil seal rubber body 1 is provided with an annular clamping groove with an L-shaped section, and an outer wrapping framework 2 is clamped and connected to play a role in protecting and matching the whole oil seal and sealing fluid, and the metal outer wrapping framework 2 is made of 304L, 316L or 316L materials;
a metal shaping framework 3 is arranged in the oil seal rubber body 1, a clamping groove is formed in the inner end face of the oil seal rubber body, an oil seal spring 4 is installed in a clamped mode, and the oil seal spring 4 is made of 304L, 316L or 316L.
An annular deformation groove 5 is arranged on the outer end face of the oil seal rubber body.
The upper part and the lower part of the oil seal rubber body 1 where the concave sealing surface is positioned are a main sealing lip 6 and an auxiliary sealing lip 7 respectively;
a plurality of uniformly arranged clip-shaped elastic sheets 8 are arranged on the inner edge of the metal shaping framework 3, the cross section of each clip-shaped elastic sheet 8 is matched with the concave sealing surface, and the upper end and the lower end of each clip-shaped elastic sheet 8 are respectively positioned at the main sealing lip 3 and the auxiliary sealing lip 4;
the outer edge of the metal shaping framework is provided with a plurality of shaping elastic sheets 9 which are uniformly distributed, and the shaping elastic sheets 9 are arranged in the oil seal rubber body 1 at the inner side of the outer wrapping framework 2;
the pressing force of the main lip to the shaft can be improved, the effect of the pressing force can be maintained, and the shape of the whole oil seal is protected from being changed easily.
