Abstract
The utility model provides a kind of hub bearing end face seal structure, the inner ring on the outside of double-row conical bearing（2）At big end surface chamfer and axis（5）Between y-type seal ring is installed（1）, inner side inner ring（3）At big end surface chamfer and axis（5）Between O-ring seal is installed（4）.With the high leakproofness between enhancing axis and inner ring, muddy water and debris is prevented to enter between axis and bearing inner race and prevent lubricating grease/oil in bearing from leaking.The service life of automobile hub bearing can effectively be extended.
Description
Technical field
A kind of automobile hub bearing end face seal structure is the utility model is related to, more specifically, it relates to which one kind can
Prevent impurity from entering the hub bearing end face seal structure that Bearing inner can prevent lubricating grease/oil leakage again.
Background technology
With the high speed development of automobile industry and its supporting industries concerned, each manufacturer and user are to vehicle or parts
The quality of product also made higher requirement, and not have sealing device between automobile hub bearing inner ring and axis at present, extraneous
The gap that muddy water and debris easily contradict end by double inner ring small end faces of bearing again by the gap of axis and bearing inner race enters axis
Hold internal so as to cause the damage of bearing, inhibition is risen to the lubrication of bearing, so that bearing service life is reduced, bearing point
The solution cleaning frequency is short, improves customer using cost；Sealing performance is bad at the same time, and the lubricating grease or lubricating oil of Bearing inner are easy
Leakage, lubricating grease consumption is big, influences operating environment cleaning, increases the use cost of bearing.
The content of the invention
For deficiency of the prior art, the utility model aims to provide a kind of automobile hub bearing end of good seal performance
Surface seal structure.
To solve the above-mentioned problems, the technical solution of the utility model is：A kind of hub bearing end face seal structure,
It is big that y-type seal ring, the inner ring of inner side are installed between axis at inner ring big end surface chamfer on the outside of double-row conical bearing
O-ring seal is installed at end chamfer between axis.
The beneficial effects of the utility model are：The sealing structure that the utility model is taken has between enhancing axis and inner ring
High leakproofness, prevents muddy water and debris from entering between axis and bearing inner race and prevent lubricating grease/oil in bearing from leaking in which can imitate,
So as to extend the service life of bearing.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment；
In figure：1st, y-type seal ring, 2, outside inner ring, 3, inner side inner ring, 4, o type sealing rings, 5, axis.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Be provided with the outside of double-row conical bearing at 2 big end surface chamfer of inner ring between axis 5 rubber y-type seal ring 1,
RUBBER O type sealing ring 4 is installed between axis 5 at 3 big end surface chamfer of inner side inner ring.Facts have proved with enhancing axis and inner ring it
Between high leakproofness, prevent muddy water and debris from entering between axis and bearing inner race and prevent lubricating grease/oil in bearing from leaking.
