Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, a kind of turntable sealing dress is provided It sets, enhances the integral sealing ability of sealing device, avoid outside air and largely enter, and reduce to a certain extent interior The generation and diffusion of portion's noise.
The present invention is to be achieved by the following technical programs:
A kind of turntable sealing device, including seal casinghousing, turntable, shaft and rolling bearing, the seal casinghousing include upper Sealing plate, lower sealing plate and the cavity between the upper sealing panel and lower sealing plate, the upper sealing panel connect rolling bearing, Upper sealing panel and lower sealing plate contact position are equipped with annular groove and sealing ring, and the sealing ring is ordinatedly socketed in the annular In groove, and annular groove bottom, there are atmospheric pressure cavity, the seal casinghousing side is additionally provided with exhaust tube, and the exhaust tube connection is outer Portion and atmospheric pressure cavity, for extracting the air in atmospheric pressure cavity out, and exhaust tube is equipped with valve, control exhaust tube switch.
According to the above technical scheme, it is preferable that sealing ring lower potion is made of elastic material, and the width of sealing ring lower potion omits Greater than the width of annular groove.
According to the above technical scheme, it is preferable that in lower sealing plate upper surface, the sealing ring is fixed to be connected for annular groove setting It connects in upper sealing panel lower surface.
According to the above technical scheme, it is preferable that upper sealing panel and lower sealing plate contact position be additionally provided with a circle air-borne sound every Soundboard, the air-borne sound soundproof plate are arranged on the inside of sealing ring.
The beneficial effects of the present invention are: by being arranged and can be tightly sleeved at upper sealing panel and lower sealing plate link position Sealing ring and annular groove, and by the way that atmospheric pressure cavity is arranged inside annular groove, so that energy between sealing ring and annular groove It is enough compressed by air pressure, connection is even closer, solves the problems, such as sealing device link position poor sealing effect, enhances sealing The integral sealing ability of device, avoids outside air and largely enters, and reduces the generation of internal noise to a certain extent And diffusion.
Detailed description of the invention
Fig. 1 shows schematic diagram of main cross-sectional structure of embodiment according to the present invention.
In figure: 1. sealing rings, 2. annular grooves, 3. atmospheric pressure cavities, 4. lower sealing plates, 5. upper sealing panels, 6. cavitys, 7. take out Tracheae, 8. valves, 9. turntables, 10. rolling bearings, 11. shafts, 12. soundproof plates.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and most The present invention is described in further detail for good embodiment.
As shown, the present invention provides a kind of 9 sealing device of turntable, including seal casinghousing, turntable 9 and turns shaft 11 Dynamic bearing 10, the seal casinghousing include upper sealing panel 5, lower sealing plate 4 and between the upper sealing panel 5 and lower sealing plate 4 Cavity 6, the upper sealing panel 5 connects rolling bearing 10, and upper sealing panel 5 and lower 4 contact position of sealing plate are equipped with annular groove 2 And sealing ring 1, the sealing ring 1 are ordinatedly socketed in the annular groove 2, and 2 bottom of annular groove is there are atmospheric pressure cavity 3, The seal casinghousing side is additionally provided with exhaust tube 7, the exhaust tube 7 be connected to it is external with atmospheric pressure cavity 3, for will be in atmospheric pressure cavity 3 Air extraction, and exhaust tube 7 is equipped with valve 8, control exhaust tube 7 switchs.By being connect in upper sealing panel 5 with lower sealing plate 4 The sealing ring 1 and annular groove 2 that can be tightly sleeved are set at position, and by the way that atmospheric pressure cavity 3 is arranged inside annular groove 2, So that can be compressed by air pressure between sealing ring 1 and annular groove 2, connection is even closer, solves sealing device connection position The problem of setting poor sealing effect enhances the integral sealing ability of sealing device, avoids outside air and largely enter, and one Determine the generation and diffusion that reduce internal noise in degree.
According to above-described embodiment, it is preferable that 1 lower part of sealing ring is made of elastic material, and the width of 1 lower part of sealing ring Slightly larger than the width of annular groove 2.The width of sealing ring 1 is arranged to the width slightly larger than annular groove 2, enables to seal Circle 1 sealing effect it is stronger, in atmospheric pressure cavity 3 after evacuating air, flexible 1 lower part of sealing ring will receive extruding and it is tight It tightly fills in annular groove 2, improves whole sealing performance.
According to above-described embodiment, it is preferable that for the setting of annular groove 2 in lower 4 upper surface of sealing plate, the sealing ring 1 is fixed It is connected to 5 lower surface of upper sealing panel.
According to above-described embodiment, it is preferable that upper sealing panel 5 and lower 4 contact position of sealing plate be additionally provided with a circle air-borne sound every Soundboard 12, the setting of air-borne sound soundproof plate 12 is in 1 inside of sealing ring.Since turntable 9 can generate largely in 6 inner rotation of cavity Noise, by the inside of sealing ring 1 be arranged air-borne sound soundproof plate 12, internal noise can be prevented to external diffusion, reduced Noise pollution.
