Abstract
The utility model is related to a kind of sealing structure, particularly bearing in pump case non-contact type end cap.There is through hole at bearing in pump case non-contact type end cap, including bearing box end cap, described bearing box end cap center, for through main shaft, described bearing box end cap medial surface to be provided with oil guide groove；Described Oil Guide channel opening is towards bearing.The bearing in pump case non-contact type end cap that the utility model is provided, the main shaft disc and bearing box end cap of total rotation are, without any contact, so service life is very long, and without any maintenance, to eliminate the trouble for frequently changing rubber seal.
Description
Technical field
The utility model is related to a kind of sealing structure, particularly bearing in pump case non-contact type end cap.
Background technology
In bearing housing, currently available technology mainly includes main shaft, bearing, axle to the main shaft of many plant equipment such as water pump
Case, bearing (ball) cover and rubber seal are held, bearing plays a part of support and continuous rotation to main shaft, on main shaft and bearing housing
Bearing (ball) cover, end cap and the cylindrical sealing for refilling equipped with rubber seal, realizing whole bearing housing of main shaft axle stretch end are equipped with,
After main shaft long-time rotating operation, the part of the cylindrical contact of lip and main shaft of rubber seal is easily worn and torn, and causes sealing to be lost
Effect, oil leak even can scrap main shaft when serious.So the sealing service life of this structure is short, and safeguard the work changed
Measure also very big.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of good seal performance, long service life
And the bearing housing axle stretch end sealing structure of Maintenance free.
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, is used for
Through main shaft, described bearing box end cap medial surface is provided with 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 is raised 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 causes Oil Guide channel opening
Expand, by oily water conservancy diversion to bearing housing.
Backflash is provided with the described bearing box end cap through-hole wall relative with main shaft；Described backflow trench bottom is set
There is return port.
The bearing in pump case non-contact type end cap that the utility model is provided, the main shaft disc and bearing of total rotation
Case end cap is, without any contact, so service life is very long, and without any maintenance, to eliminate frequently replacing rubber close
The trouble of envelope.
Brief description of the drawings
Fig. 1 is that bearing in pump case non-contact type end cap of the present utility model installs mplifying structure schematic diagram；
Fig. 2 is bearing in pump case non-contact type end cap scheme of installation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model 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 the center of lid 2, for through main shaft 1, the described medial surface of bearing box end cap 2 to be provided with oil guide groove 5；Described oil guide groove 5
It is open towards bearing.
There is projection the described opening of oil guide groove 5 on the side wall of main shaft 1, and described projection is open towards oil guide groove 5.
The side wall that described oil guide groove 5 is open away from main shaft 1 is Oil Guide inclined-plane 7, and described Oil Guide inclined-plane 7 causes oil guide groove
5 enlarged opens, by oily water conservancy diversion to bearing housing.
Backflash 3 is provided with described bearing box end cap 2 through-hole wall relative with main shaft 1；The described bottom of backflash 3
It is provided with return port 4.
The oil guide groove 5 of projection is machined with the bearing box end cap 2, Oil Guide inclined-plane 7 is also machined with.When main shaft 1 revolves at a high speed
When turning, the lubricating oil in bearing housing throws away in splashing shape under the drive of bearing roller to surrounding, and the lubricating oil for throwing away falls axle
Hold on the inwall inclined-plane 7 of case end cap, a part of lubricating oil flows back to bearing housing along the inwall inclined-plane 7 of bearing box end cap 2；Another part
Under gravity to whereabouts, fall in the oil guide groove 5 of bearing box end cap 2, bearing housing is flowed back to along oil guide groove 5, this is
Seal together, also second sealing, by Oil Guide inclined-plane 7 above and the collective effect of oil guide groove, can basic guarantee
Bearing housing is sealed, but enters into bearing and bearing housing end by still having micro lubricating oil after prolonged operation
In gap 6 between lid, this parts of lubricating oil can be thrown out in the presence of main shaft rotation, be 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, so as to reach mesh of the long-play without leakage
's.Because the main shaft and bearing box end cap of total rotation are that, without any contact, structure is very simple, so service life
It is very long, and without any maintenance, eliminate the trouble for frequently changing rubber seal.
