Drawings
Fig. 1 shows a front view cross-sectional structural schematic diagram according to an embodiment of the present invention.
In the figure: 1. the sealing ring, 2, the annular groove, 3, the air pressure cavity, 4, the lower sealing plate, 5, the upper sealing plate, 6, the cavity, 7, the exhaust pipe, 8, the valve, 9, the turntable, 10, the rotating bearing, 11, the rotating shaft and 12, the sound insulation plate.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model provides a carousel 9 sealing device, including seal housing, carousel 9, pivot 11 and rolling bearing 10, seal housing includes upper seal plate 5, and lower seal plate 4 reaches cavity 6 between upper seal plate 5 and the lower seal plate 4, rolling bearing 10 is connected to upper seal plate 5, and upper seal plate 5 is equipped with annular groove 2 and sealing washer 1 with lower seal plate 4 contact position, 1 cup joints with the cooperation of sealing washer in the annular groove 2, and 2 bottoms of annular groove leave atmospheric pressure chamber 3, seal housing side still is equipped with exhaust tube 7, exhaust tube 7 communicates outside and atmospheric pressure chamber 3 for take the air in atmospheric pressure chamber 3 out, and be equipped with valve 8 on the exhaust tube 7, control exhaust tube 7 switch. Through setting up sealing washer 1 and the annular groove 2 that can closely cup joint in last closing plate 5 and 4 hookup location department of lower closing plate, and through setting up atmospheric pressure chamber 3 in annular groove 2 inside, make and compress tightly through atmospheric pressure between sealing washer 1 and the annular groove 2, it is inseparabler to connect, the problem that sealing device hookup location sealing effect is poor is solved, sealing device's whole sealing ability has been strengthened, the outside air has been avoided getting into in a large number, and the production and the diffusion of internal noise have been reduced to a certain extent.
According to the above embodiment, preferably, the lower portion of the sealing ring 1 is made of elastic material, and the width of the lower portion of the sealing ring 1 is slightly larger than the width of the annular groove 2.
