Description
Technical field
The present invention relates to a kind of sealing ring, especially refers to a kind of waterproof grommet for bearing in fact.
Background technology
Global warming, southern area city rainy season waterlogging increase, and enter energy for the anti-foreign matter of family car bearing
The lifting of power claims, currently known bearing in use, due to bearing when rotated lubricating grease be extruded into outside, and
Bearing really rotates in the case of unlubricated fat, so the service life of bearing substantially reduces；Since bearing is using
Environment is different, and exterior water, grease, foreign matter penetrate into Bearing inner, bearing grease is gone bad or, into impurity, cause bearing
Service life substantially reduces, in order to overcome bearing in rotation lubricating grease be extruded into outside the problem of and portion water, grease, foreign matter
Bearing inner is penetrated into, patent of the present invention carries out innovative design to bearing seal structure, by pressure conversion, with fluid motion characteristics
Method, the lubricating grease in bearing is squeezed less than outside, while the water in outside, grease, foreign matter are not entered inside bearing yet.
The content of the invention
Present invention aims at provide a kind of waterproof grommet for bearing, with solve bearing in use prevent
The problem of water, dust-proof, water-impervious, anti-overflow fat, especially on the premise of not changing primitive axis and holding dimensional accuracy, can reach water, prevent
Dirt, water-impervious, the effect of anti-overflow fat.
According to technical solution provided by the invention, the waterproof grommet for bearing, including positioned at sealing ring outer rim
The first outer lip and the second outer lip, and the first epipharynx positioned at sealing ring inner edge, the second epipharynx, the 3rd epipharynx, the 4th epipharynx；The
The first groove is formed between one outer lip and the second outer lip；The second groove, the second epipharynx and are formed between first epipharynx and the second epipharynx
The 3rd groove is formed between three epipharynxs；4th epipharynx is directed toward the axial direction of sealing ring.
First outer lip, the second outer lip, the first epipharynx, the second epipharynx and the 3rd epipharynx are pointed generally in the radial direction of sealing ring.
The waterproof grommet, it is characterised in that the bearing seal coil structures are an integral molding structure.
The waterproof grommet of the present invention, the first outer lip of Y-shaped design are subject to external dust, water, grease, the pressure of debris
When, one reaction force of lip is passed to, lip is contacted with bearing outer ring contact surface closer, the more presses the more tight, ensures sealing
Performance；Prevent external water, grease from entering Bearing inner from outer ring；Second outer lip of Y " shapes design is installed on bearing outer ring inner headed face
On Special seal groove in, with seal groove be interference fitted, ensure that firmly installing for sealing ring, while prevent the oil of Bearing inner
Seborrhea goes out；First epipharynx of " hand " shape design be subject to external dust, water, grease, debris pressure when, it is anti-to pass to lip one
Active force, makes lip be contacted with bearing outer ring contact surface closer, the more presses the more tight, ensures sealing performance；Prevent external water, grease
Enter Bearing inner from inner ring；Second epipharynx prevents Bearing inner grease from overflowing bearing, the 3rd epipharynx further pre- waterproof, grease
Debris, dust enter Bearing inner, and the 3rd epipharynx prevents Bearing inner grease from overflowing bearing, control bearing internal grease movement side
To making grease, formation greasing cycle, avoids grease from moving out, prevent grease from overflowing toward Bearing inner movement.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the present invention.
Fig. 2 is outer ring and the sealing ring contact structures partial enlarged view of the present invention.
Fig. 3 is the inner ring and sealing ring contact structures partial enlarged view of the present invention.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in Fig. 1, waterproof grommet of the present invention is molded using the elastomeric material integral production of high resiliency, low friction, including
Positioned at the first outer lip 1 and the second outer lip 2 of sealing ring outer rim, and the first epipharynx 3 positioned at sealing ring inner edge, the second epipharynx 4,
Three epipharynxs 5, the 4th epipharynx 6；The first groove is formed between first outer lip 1 and the second outer lip 2；Shape between first epipharynx 3 and the second epipharynx 4
Into the second groove, the 3rd groove is formed between the second epipharynx 4 and the 3rd epipharynx 5；4th epipharynx 6 is directed toward the axial direction of sealing ring.
First outer lip 1, the second outer lip 2, the first epipharynx 3, the second epipharynx 4 and the 3rd epipharynx 5 are pointed generally in the footpath of sealing ring
To.First outer lip 1 of Y " shapes design be subject to external dust, water, grease, debris pressure when, it is anti-to pass to the first outer lip 1 one
Active force, makes the first outer lip 1 be contacted with bearing outer ring contact surface closer, the more presses the more tight, ensures sealing performance；Prevent outside
Water, grease enter Bearing inner from outer ring；Second outer lip 2 of Y " shapes design is installed on the Special seal on bearing outer ring inner headed face
In groove, it is interference fitted with seal groove, ensure that firmly installing for sealing ring, while prevent the grease of Bearing inner from overflowing；" hand "
First epipharynx 3 of shape design be subject to external dust, water, grease, debris pressure when, pass to that one, 3 side of the first epipharynx is anti-to be made
Firmly, the first epipharynx 3 is contacted with bearing outer ring contact surface closer, the more press the more tight, ensure sealing performance；Prevent external water,
Grease enters Bearing inner from inner ring；Second epipharynx 4 prevents Bearing inner grease from overflowing bearing, and the 3rd epipharynx 5 further prevents
Water, oil impurity, dust enter Bearing inner, and the 4th epipharynx 6 prevents Bearing inner grease from overflowing bearing, controls bearing interior oil
The fat direction of motion, makes grease be moved toward Bearing inner, forms greasing cycle, avoids grease from moving out, prevent grease from overflowing.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
