Abstract

The present invention is provided, in two inner rings of double-row conical bearing（1）Inner side is provided with the circular age of a draught animal, with spring retainer（4）Two inner rings of connection（1）, O-ring seal（3）Positioned at two inner rings（1）At the circular age of a draught animal that combination is formed, O-ring seal（3）Outer rim is equipped with inner ring（2）.Can ensure that oil or water between inner ring and the axle of cooperation can not invade Bearing inner, more can effectively prevent the lubricating grease of Bearing inner from leaking, so as to extend the service life of bearing unit.

Description

Seal between bearing inner race small end face
Technical field
The present invention relates to a kind of sealing of automobile hub bearing, especially with regard to a kind of automobile hub bearing inner ring small end face it Between seal.
Background technology
With the continuous development of automobile industry correlation technique, the performance and resistance to muddy water to its hub unit reducing energy consumption Requirement more and more higher, relative, the double inner ring tapered roller bearing units of wheel hub are used as important rotation component, Yin Qicai With the design of double inner rings, gap is carried between its bearing inner race small end face, so the grease between bearing and axle is easily accessible Bearing is simultaneously obscured with the lubricating grease of its inside, affects the service life of bearing, therefore, from Bearing inner via two inner ring small ends Sealing between face to the axletree surface coordinated with bearing inner race is extremely important.
The content of the invention
For deficiency of the prior art, the present invention is intended to provide sealing between a kind of bearing inner race small end face.
In order to solve the above problems, the technical solution of the present invention is：Seal between a kind of bearing inner race small end face, The circular age of a draught animal is provided with the inside of two inner rings of double-row conical bearing, two inner rings are connected with spring retainer, O-ring seal is located at Two inner rings were combined at the circular age of a draught animal to be formed, and O-ring seal outer rim is equipped with sealing collar.
Described sealing collar section is grooved, and two side elevations are dentation, and groove-root diameter is less than O-ring seal external diameter.
The invention has the beneficial effects as follows：Can ensure that oil or water between inner ring and the axle of cooperation can not invade Bearing inner, The lubricating grease of Bearing inner more can be effectively prevented to leak, so as to extend the service life of bearing unit.
Description of the drawings
Fig. 1 is sealed structural representation between the bearing inner race small end face of the embodiment of the present invention；
Stereograms of the Fig. 2 for the sealing collar 2 of the embodiment of the present invention.
In figure：1st, inner ring, 2, sealing collar, 3, O-ring seal, 4, spring retainer.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described further.
The circular age of a draught animal is provided with the inside of two inner rings 1 of double-row conical bearing, two inner rings 1 is connected with spring retainer 4, , at the circular age of a draught animal that two combinations of inner ring 1 are formed, 3 outer rim of O-ring seal is equipped with sealing collar 2, sealing for O-ring seal 3 2 section of collar is grooved, and two side elevations are dentation（See accompanying drawing 2）, groove-root diameter is less than 3 external diameter of O-ring seal, sealing collar 2 Block O-ring seal 3, be pressed in bearing inner race small end face opening at, reach jointly sealing function.

Claims (2)
