Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged diagram at A place in Fig. 1;
Wherein: 1, bent axle, 11, rotatingshaft, 2, transparent cover, the 3, first inner split ring, the 4, first outer spacer ring, the 5, second outer spacer ring, the 6, second inner split ring.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of speed reducer made up mechanical seal structure, there is bent axle 1, bent axle 1 has rotatingshaft 11, rotatingshaft 11 packs transparent cover 2 into from left side, transparent cover 2 is positioned at rotatingshaft 11 low order ends, transparent cover 2 has the first vertical block, the first inner split ring 3 is installed in transparent cover 2 left sides, the first inner split ring 3 has the second vertical block, the first vertical block of transparent cover 2 is contrary with the bearing of trend of the second vertical block of the first inner split ring 3, and the second vertical block of the first vertical block of transparent cover 2 and the first inner split ring 3 forms first layer labyrinth seal.
The outer stopper of the outer spacer ring 4 of the first outer spacer ring 4, the first is installed in the first inner split ring 3 left sides and the cooperation of the inner stopper of transparent cover 2 contacts.
The first outer spacer ring 4 has the 3rd vertical block, and the first outer spacer ring 4 is by the 3rd vertical block and the first inner split ring 3 sealings.
The first outer spacer ring 4 left sides are installed the second inner split ring 6, the second inner split rings 6 and are had the 4th vertical block.The second inner split ring 6 left sides are installed the outer spacer ring 5 of the second outer spacer ring 5, the second and are had the 5th vertical block.The 5th vertical block of the 4th vertical block of the second inner split ring 6 and the second outer spacer ring 5 forms second layer labyrinth seal.
The first inner split ring 3 hot jackets are inserted in rotatingshaft 11, the first inner split rings 3 and rotatingshaft 11 interference fit.
The second inner split ring 6 hot jackets are inserted in rotatingshaft 11, the second inner split rings 6 and rotatingshaft 11 interference fit.
A speed reducer, has above-mentioned speed reducer made up mechanical seal structure, and the second outer spacer ring 5 left side covers have bearing, gear.
