Abstract
The invention relates to a seal structure, especially for an oil flinger of a pump bearing box. The oil flinger of the pump bearing box includes a sleeve, wherein the inner wall of the sleeve is provided with a boss. The boss is used to connect with the principal shaft; the front end of the sleeve is provided with an annular thin wall; the thin wall is arranged between the end cap of the bearing box and the principal shaft; the outer wall of the thin wall is provided with plus threads and left-hand threads corresponding to the direction of rotation of the principal shaft; an angular disc is arranged behind the thin wall, and the disc is fixed on the outer wall of the sleeve. In the whole structure of the oil flinger of the pump bearing box, the rotating oil flinger of the principal shaft is no touch with the end cap of the bearing box, so the oil flinger is long in service life, free of maintenance, and the trouble of frequently replacing rubber seals is avoided.
Description
Technical field
The present invention relates to a kind of sealing structure, particularly bearing in pump case disc.
Background technology
The main shaft of many plant equipment such as water pump is contained in bearing housing, and currently available technology mainly includes main shaft, bearing, axle
Hold case, bearing (ball) cover and rubber seal, bearing plays to main shaft and supports and the continuous effect rotating, on main shaft and bearing housing
It is equipped with bearing (ball) cover, end cap and cylindrical the refilling of main shaft axle stretch end are furnished with rubber seal, realize the sealing of whole bearing housing,
After the long-time rotating operation of main shaft, the lip of rubber seal is cylindrical with main shaft partly easily wearing and tearing of contacting, lead to sealing to be lost
Effect, oil leak, even main shaft can be made to scrap when serious.So the sealing service life of this structure is short, and safeguard the work of replacing
Measure also very big.
Content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of good seal performance, long service life and nothing
The bearing housing axle stretch end sealing structure that need to safeguard.
Concrete technical scheme is：
Bearing in pump case disc, including sleeve, described sleeve lining has boss, and described boss is used for being connected with main shaft；
Described barrel forward end has the thin-walled of annular, and described thin-walled is arranged between bearing box end cap and main shaft；Described thin-walled
The positive and negative pitch thread corresponding with main shaft direction of rotation is had on outer wall；Described thin-walled rear, also the disc of annular, described
Disc is fixed on the outer wall of sleeve.
Described disc includes the fundamental base leaning forward, and described fundamental base is pyramidal structure, and larger one end open is towards thin
Wall, less one end open is fixed on sleeve outer wall.
The larger one end open of described fundamental base is also associated with the Oil Guide circle of annular；The described Oil Guide circle being is located at oil guide groove
Notch at.
Described fundamental base is slidably matched with the boss of bearing box end cap.
The bearing in pump case disc that the present invention provides, the main shaft disc of total rotation and bearing box end cap are no
Any contact, so service life is very long, and without any maintenance, eliminate the frequent trouble changing rubber seal.
Brief description
Fig. 1 is that the bearing in pump case disc of the present invention installs mplifying structure schematic diagram；
Fig. 2 is the bearing in pump case disc structural representation of the present invention；
Fig. 3 is the bearing in pump case disc scheme of installation of the present invention.
It is embodied as
The specific embodiment of the present invention is described with reference to the drawings.
As depicted in figs. 1 and 2, bearing in pump case disc, including sleeve 2, described sleeve lining has boss, described
Boss is used for being connected with main shaft 1；There is the thin-walled 9 of annular described sleeve 2 front end, and described thin-walled 9 is arranged on bearing box end cap 3
And main shaft 1 between；The positive and negative pitch thread 6 corresponding with main shaft 1 direction of rotation is had on the described outer wall of thin-walled 9；
Described thin-walled 9 rear, the also disc 8 of annular, described disc 8 is fixed on the outer wall of sleeve 2.
Described disc 8 includes the fundamental base 81 leaning forward, and described fundamental base 81 is pyramidal structure, larger one end open court
To thin-walled 9, less one end open is fixed on sleeve 2 outer wall.
The described larger one end open of fundamental base 81 is also associated with the Oil Guide circle 82 of annular；The described Oil Guide circle 82 being is located at
At the notch of oil guide groove 4.
Described fundamental base 81 is slidably matched with the boss 5 of bearing box end cap 3.
As shown in figure 3, bearing housing axle stretch end stretches out the sealing structure that bearing case portion is divided, including bearing box end cap 3 and main shaft 1
The bearing in pump case disc of upper installation, abbreviation disc.The oil guide groove 4 of projection is machined with described bearing box end cap 3, gets rid of oil
Disk is a discoid part, cylindrical on have the positive and negative pitch thread 6 corresponding with main shaft direction of rotation.When main shaft high-speed rotation,
Lubricating oil in bearing housing throws away to surrounding in splashing shape under the drive of bearing roller, and the lubricating oil throwing away falls bearing housing end
On the inner hole wall of lid 3, a part of lubricating oil flows back to bearing housing along bearing box end cap 3 inner hole wall；Another part is in the work of gravity
With lower to whereabouts, a portion is fallen in the oil guide groove 4 of bearing box end cap 3, flows back to bearing housing along oil guide groove 4, another portion
Point fall on disc, disc is and then main shaft 1 high-speed rotation together, this parts of lubricating oil by continuing to be thrown out of,
Still can flow back in bearing housing along oil guide groove 4 and bearing box end cap 3 inwall eventually；It is more than first sealing.
Also have second sealing, by the collective effect of oil guide groove 4 above and disc, can basic guarantee bearing
The sealing of case, but still have, after long operation, the boss 5 that micro lubricating oil enters into bearing box end cap 3
In gap 7 and disc between, this parts of lubricating oil can be in the presence of disc external screw thread 6, finally or lubricating oil
Take back bearing housing, thus the purpose reaching long-play and not leaking.Main shaft disc and axle due to total rotation
Holding case end cap is no any contact, so service life is very long, and without any maintenance, eliminates frequent replacing rubber
The trouble of sealing.
