Description
Technical field:
The present invention relates to a kind of sealing devices, and in particular to a kind of vertical non-contact sealing arrangement.
Background technique:
It is vertical and high-speed axis that bevel gear box output end is set on certain aviation casing test bay, and axis maximum speed is more than 2000r/min, with
Casing input terminal is connected by gear coupling；In axis high speed rotation, axis, shaft coupling and cabinet are formed by easy shape in space
At negative pressure, output end oil leak is caused.So designing a kind of vertical non-contact sealing arrangement for speedy carding process shaft end is very
It is necessary.
Summary of the invention:
The object of the present invention is to provide a kind of vertical non-contact sealing arrangement for speedy carding process shaft end, which is solved
Gear-box vertical output end Leakage, can be realized by the vertical non-contacting sealing structure being made of three oil baffle structures
The sealing of high-speed output end, structure is simple, and oil return point is more, and oil return area is big, not easy oil leakage, can be used for high revolving speed shafting sealing.
The technical solution adopted by the present invention are as follows: a kind of vertical non-contact sealing arrangement, including changeover mechanism, further include first
Disc, can oil leak get rid of oil the second disc, be capable of oil leak oil scraper ring, for disc positioning disc positioning sleeve
With speedy carding process end clamp plate；First disc is installed on the vertical output shaft of changeover mechanism, the second disc peace
Loaded below the first disc, the oil scraper ring is installed below the second disc, and the disc positioning sleeve is installed on gear oil
Below ring, the speedy carding process end clamp plate is installed below oil scraper ring.
Further, it is equipped with annular seal groove at the inner ring of second disc, is equipped with O-ring annular groove at outer ring,
The middle section of the inner ring and outer rings is provided with oil leaking hole and disc slot.
Further, oil leak aperture is equipped at the outer ring of the oil scraper ring.
Further, the disc positioning sleeve is equipped with annular groove, and the annular groove is connected to the oil return hole of changeover mechanism.
Further, the positioning of disc and oil scraper ring is realized by being provided with the disc positioning sleeve of disc slot.
Further, the second disc and gear by being installed on the first disc of rotary shaft, being installed on changeover mechanism
Oil ring realizes oil return and sealing.
Beneficial effects of the present invention: a kind of vertical non-contact sealing arrangement for speedy carding process shaft end is provided, this is close
Seal apparatus solves the vertical output end Leakage of gear-box, passes through the vertical non-contacting seal being made of three oil baffle structures
Structure can realize the sealing of high-speed output end, and structure is simple, and oil return point is more, and oil return area is big, not easy oil leakage, can be used for high revolving speed
Shafting sealing, design is rationally, securely and reliably, economic and practical, is easy to promote and use on a large scale.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of embodiment one.
Specific embodiment:
Embodiment one
Referring to Fig.1, a kind of vertical non-contact sealing arrangement, including changeover mechanism 1, further include the first disc 2, can oil leak get rid of
Oil the second disc 3, be capable of oil leak oil scraper ring 4, for disc positioning disc positioning sleeve 5 and speedy carding process side pressure
Plate 6；First disc 2 is installed on the vertical output shaft of changeover mechanism 1, and second disc 3 is installed on first and gets rid of
2 lower section of oil ring, the oil scraper ring 4 are installed on 3 lower section of the second disc, and the disc positioning sleeve 5 is installed under oil scraper ring 4
Side, the speedy carding process end clamp plate 6 are installed on 4 lower section of oil scraper ring；Annular seal groove is equipped at the inner ring of second disc 3
11, O-ring annular groove 8 is equipped at outer ring, the middle section of the inner ring and outer rings is provided with oil leaking hole 10 and disc slot 9；Institute
It states and is equipped with oil leak aperture at the outer ring of oil scraper ring 4；The disc positioning sleeve 5 is equipped with annular groove 7, the annular groove 7 and switching machine
The oil return hole of structure 1 is connected to.
First disc is fixed on vertical output shaft as first of oil baffle structure, and most of oil is introduced second and gets rid of oil
Ring oil leaking hole flows into disc slot through oil leaking hole, and flows into gear case oil bottom case by changeover mechanism oil return hole；Output shaft passes through tooth
Formula shaft coupling is connect with casing input terminal, and annular seal groove is equipped at the second disc inner ring, will flow into shaft coupling and sealing fills
A small amount of lubricating oil between setting introduces disc oil leaking hole；This structure keeps off oil seal as second；Fail to introduce disc oil leaking hole
Lubricating oil, can through oil scraper ring flow into disc positioning sleeve, and by changeover mechanism oil return hole flow into gear case oil bottom case, be provided with back
The oil scraper ring of oilhole and disc positioning sleeve equipped with oil return annular groove keep off oil seal structure as third road.By three oil baffle structures
The vertical non-contact sealing arrangement of composition has structure simple, and oil return point is more, and oil return area is big, not easy oil leakage, can be used for high turn
The features such as fast shafting seals.
