Abstract
The utility model discloses an intelligent SF6 circuit breaker rotates seal structure, including sealed axle, axle sleeve, closing plate and clamp plate, sealed axle cup joints simultaneously in axle sleeve and clamp plate, and the axle sleeve cup joints in the closing plate, inlays a plurality of inside seal circles of hugging closely sealed axle on the inside wall of axle sleeve, inlays a plurality of external seal circles of hugging closely the closing plate on the lateral wall of axle sleeve, about the axle sleeve inside wall both ends with seal up spool between be equipped with two bearings, the clamp plate lies in the left side of axle sleeve and closing plate, and the clamp plate is fixed with the closing plate through lieing in on it the bolt of lower part mutually. The utility model discloses it is nimble to realize that sealed axle rotates, and frictional resistance reduces, and transmission efficiency improves, and simple reliable.
Description
Technical field
The utility model is the rotational sealing structure of the intelligent SF6 circuit breaker of a kind of 40.5KV, also can be used for the rotary seal of other high pressure and ehv power transmission equipment.
Background technology
At present, the high-voltage sf6 circuit breaker action bars rotary seal overwhelming majority adopts axle sleeve and V-shaped seal ring or axle sleeve and O RunddichtringO Sealing Technology, bearing plate, axle sleeve flange and sealing plate connect, drive action bars direct acting by axis of rotation, this structural disadvantages is that design is complicated, cost is high, high to parts machining technological requirement level, assembling difficulty, frictional resistance are comparatively large, transmission efficiency is low.
Summary of the invention
For solving the problems of the technologies described above, a kind of structure of innovative design is simple, good seal performance, transmission efficiency are high and the rotational sealing structure that cost is extremely low, and its technical scheme taked is:
This structure comprises seal shaft, axle sleeve, sealing plate and pressing plate, seal shaft is socketed in axle sleeve and pressing plate simultaneously, and axle sleeve is socketed in sealing plate, the madial wall of axle sleeve is embedded with multiple inner seal ring being close to seal shaft, the lateral wall of axle sleeve is embedded with multiple be close to sealing plate exterior seal ring, be provided with two bearings between the two ends, left and right of axle sleeve madial wall and seal shaft, pressing plate be positioned at axle sleeve and sealing plate left side, and pressing plate is fixed by the bolt and sealing plate being located thereon bottom.
The utility model can realize seal shaft and rotate flexibly, and frictional resistance reduces, and transmission efficiency improves, and simple and reliable, and parts machining technological requirement level reduces, easy to assembly, greatly reduces axle sleeve outside dimension, effectively reduces production cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, seal shaft 1 is socketed in axle sleeve 3 and pressing plate 9 simultaneously, and axle sleeve 3 is socketed in sealing plate 5, the madial wall of axle sleeve 3 is embedded with multiple inner seal ring 2 being close to seal shaft 1, the lateral wall of axle sleeve 3 is embedded with multiple exterior seal ring 4 being close to sealing plate 5, bearing 6 and bearing 7 is provided with between the two ends, left and right of axle sleeve 3 madial wall and seal shaft 1, ensure that seal shaft 1 rotates flexibly, the more important thing is and ensure that inner seal ring 2 decrement controls in setting range, pressing plate 9 is positioned at the left side of axle sleeve 3 and sealing plate 5, and pressing plate 9 is fixed with sealing 5 plates by the bolt 8 being located thereon bottom.
