Abstract
The invention relates to a sealing structure, in particular to a non-contact type end cover for a bearing box for a pump. The non-contact type end cover for the bearing box for the pump comprises a bearing box end cover; a through hole is formed in the centre of the bearing box end cover and is used for a main shaft to penetrate; an oil guide groove is formed in the inside surface of the bearing box end cover; the opening of the oil guide groove faces a bearing. According to the non-contact type end cover for the bearing box for the pump provided by the invention, a rotary main shaft oil throwing disc and the bearing box end cover of the whole structure are not in contact with each other, so that the service life is very long; moreover, any maintenance is not required, and the trouble caused by frequently replacing rubber seals is avoided.
Description
Technical field
The present invention relates to a kind of sealing structure, particularly bearing in pump case non-contact type end cap.
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 non-contact type end cap, including bearing box end cap, there is through hole at described bearing box end cap center, for through
Main shaft, described bearing box end cap medial surface has oil guide groove；Described Oil Guide channel opening is towards bearing.
Described Oil Guide channel opening has projection on the side wall of main shaft, and described projection is towards Oil Guide channel opening.
Described Oil Guide channel opening is Oil Guide inclined-plane away from the side wall of main shaft, and described Oil Guide inclined-plane makes Oil Guide channel opening
Expand, by oily water conservancy diversion to bearing housing.
Backflash is had on the described bearing box end cap through-hole wall relative with main shaft；Described backflow trench bottom setting
There is return port.
The bearing in pump case non-contact type end cap that the present invention provides, the main shaft disc of total rotation and bearing housing end
Lid is no any contact, so service life is very long, and without any maintenance, eliminates frequent replacing rubber seal
Trouble.
Brief description
Fig. 1 is that the bearing in pump case non-contact type end cap of the present invention installs mplifying structure schematic diagram；
Fig. 2 is the bearing in pump case non-contact type end cap 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 non-contact type end cap, including bearing box end cap 2, described bearing housing end
There is through hole at 2 centers of covering, for through main shaft 1, described bearing box end cap 2 medial surface has oil guide groove 5；Described oil guide groove 5
Opening is towards bearing.
Described oil guide groove 5 opening has projection on the side wall of main shaft 1, and described projection is towards oil guide groove 5 opening.
Described oil guide groove 5 opening is Oil Guide inclined-plane 7 away from the side wall of main shaft 1, and described Oil Guide inclined-plane 7 makes oil guide groove
5 enlarged open, by oily water conservancy diversion to bearing housing.
Backflash 3 is had on described bearing box end cap 2 through-hole wall relative with main shaft 1；Described backflash 3 bottom
It is provided with return port 4.
The oil guide groove 5 of projection is machined with described bearing box end cap 2, is also machined with Oil Guide inclined-plane 7.When main shaft 1 revolves at a high speed
When turning, the lubricating oil in bearing housing throws away to surrounding in splashing shape under the drive of bearing roller, and axle fallen by the lubricating oil throwing away
Hold on the inwall inclined-plane 7 of case end cap, a part of lubricating oil flows back to bearing housing along bearing box end cap 2 inwall inclined-plane 7；Another part
Under gravity to whereabouts, fall in the oil guide groove 5 of bearing box end cap 2, flow back to bearing housing along oil guide groove 5, this is
Seal together, also second sealing, by the collective effect on Oil Guide inclined-plane 7 above and oil guide groove, can basic guarantee
The sealing of bearing housing, but still have micro lubricating oil after long operation and enter into bearing and bearing housing end
In gap 6 between lid, this parts of lubricating oil can be thrown out in the presence of main shaft rotation, is thrown to the endoporus of bearing box end cap
On, a part directly flows back to bearing housing, and some flows into the backflash 3 of bearing box end cap, backflash along major axes orientation
Bottom is provided with return port 4, finally or lubricating oil is taken back bearing housing,.Thus the mesh reaching long-play and not leaking
's.Due to main shaft and the bearing box end cap of total rotation be no any contact, structure is very simple, so service life
Very long, and without any maintenance, eliminate the frequent trouble changing rubber seal.
