Description
Technical field
The utility model relates to a kind of bearing units, specifically, it is related to the T-type sealing structure of biserial conical bearing, it is main
To be applied to automobile industry, be used on wheel hub.
Background technique
As the requirement of the continuous development of automobile industry the relevant technologies, performance and resistance to muddy water that energy consumption is reduced to it is got over
Come higher, opposite, wheel hub conical bearing unit is as important rotation component, and the service life of hub bearing is depending on its sealing
Performance, existing bearing sealed ring elastic strength is poor, leads to poor sealing effect, and bearing is vulnerable.
Summary of the invention
Bearing outer bearing enters lubrication oil consumption in raceway and bearing in order to prevent, influences the service life of bearing, mentions
High bearing seal effect, the utility model provide a kind of bearing T shaped sealing structure of biserial cone axis, reach prevention lubricating grease and let out
Leakage.
To achieve the goals above, the technical scheme adopted by the utility model is a kind of bearing T shaped sealing of biserial cone axis
Structure including two inner rings connected through T-type spacer ring, the taper roller being set in two inner ring raceways, passes through sealing device
Two outer rings outside inner ring are connected to, two inner rings of bearing are equipped with the age of a draught animal；
The T-type spacer ring inside groove is set there are two O-ring seal；
The small rib position of inner ring is arranged in the T-type spacer ring；
Bearing two sides outer ring is equipped with plastic clasp, and plastic clasp one end is connected to outer ring stub end, and the other end is fixed on interior
The small rib position of circle；
The plastic clasp of fixed outer ring is contacted with bearing outer ring, and outer ring major part and inner-ring small flange is made to form confined space,
It prevents dust from entering, while guaranteeing that lubricating grease is stored in Bearing inner to bearing during operation；
The snap ring uses plastic material, prevents bearing outer ring end wear, can effectively be subtracted using plastics cavity shell
Light weight, and facilitate processing；
Sealing device between the small head end in outer ring and inner ring stub end is more lip type combined sealing structures；
The sharp corner and age of a draught animal clearance fit of described two inner rings, are easily installed.
Bearing seal can be improved in the T-type spacer ring for including double O-rings, prevents foreign matter from entering.
Beneficial effect by adopting the above technical scheme is: improving the leakproofness of bearing, the plastic clasp and axis of fixed outer ring
Bearing outer-ring contact makes outer ring major part and inner-ring small flange form confined space, prevents dust from entering, while guaranteeing that bearing is operating
Lubricating grease is stored in Bearing inner in the process, and the hardness of plastic material is used to be significantly lower than the hardness of bearing steel, prevents outside bearing
End wear is enclosed, weight can effectively be mitigated using plastics cavity shell, and facilitate processing.The outer ring spacer for including double O-rings can
It to improve bearing seal, prevents foreign matter from entering, by this novel seal form, bearing is made to form the sky being fully sealed
Between, effectively improve bearing life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1, inner ring, 2, taper roller, 3, outer ring, 4, plastic clasp, 5, T-type spacer ring, 6, sealing device.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
A kind of bearing T shaped sealing structure of biserial cone axis, including connected through T-type spacer ring 5 two inner rings 1, be set to two
Taper roller 2 in 1 raceway of inner ring is connected to two outer rings 3 outside inner ring 1, two inner rings 1 of bearing by sealing device 6
Equipped with the age of a draught animal；
5 inside groove of T-type spacer ring is set there are two O-ring seal；
The small rib position of inner ring 1 is arranged in the T-type spacer ring 5；
Bearing two sides outer ring 3 is equipped with plastic clasp 4, and 4 one end of plastic clasp is connected to 3 stub end of outer ring, and the other end is fixed
In the small rib position of inner ring 1；
The plastic clasp 4 of fixed outer ring 3 is contacted with bearing outer ring 3, forms 3 major part of outer ring with the small rib of inner ring 1 closed
Space prevents dust from entering, while guaranteeing that lubricating grease is stored in Bearing inner to bearing during operation；
The snap ring uses plastic material, prevents 3 end wear of bearing outer ring, can effectively be subtracted using plastics cavity shell
Light weight, and facilitate processing；
Sealing device 6 between 1 stub end of the small head end in outer ring 3 and inner ring is more lip type combined sealing structures；
The sharp corner and age of a draught animal clearance fit of described two inner rings 1, are easily installed.
The plastic clasp 4 of fixed outer ring 3 is contacted with bearing outer ring 3, and outer ring major part and inner-ring small flange is made to form confined air
Between, prevent dust from entering, while guaranteeing that lubricating grease is stored in Bearing inner to bearing during operation, and use the hard of plastic material
Degree is significantly lower than the hardness of bearing steel, prevents bearing outer ring end wear, can effectively mitigate weight using plastics cavity shell,
And facilitate processing.Bearing seal can be improved in the T-type spacer ring for including double O-rings, prevents foreign matter from entering, by this novel
Seal form makes bearing form the space being fully sealed, effectively improves bearing life.
By the machining tolerance of T-type spacer ring, works good the end-play of bearing in manufacturer, facilitate client to install, together
When can form unified bearing unit with components such as shells and processed.
