Description
Technical field
The utility model relates to a kind of water-sealed bearings, it is intended to solve waterproof and dustproof in use process, water-impervious, anti-overflow
The problem of rouge, can reach the effect of water, dust-proof, water-impervious, anti-overflow rouge especially under the premise of not changing primitive axis and holding dimensional accuracy
Fruit.
Background technique
Global warming, southern area city rainy season waterlogging increase, and enter energy for the anti-foreign matter of family car bearing
The promotion 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 where unlubricated rouge, so the service life of bearing substantially reduces；Since bearing is using
Environment is different, and external water, grease, foreign matter penetrate into Bearing inner, keeps bearing grease rotten or, into impurity, leads to bearing
Service life substantially reduces, and lubricating grease is extruded into order to overcome the problems, such as bearing in rotation water, grease, the foreign matter in outside and portion
Bearing inner is penetrated into, the utility model patent carries out innovative design to bearing seal structure, by pressure conversion, with fluid motion
The method of characteristic squeezes the lubricating grease in bearing less than outside, while the water in outside, grease, foreign matter do not enter inside bearing yet.
Summary of the invention
The utility model aim is to provide a kind of water-sealed bearing, it is intended to solve bearing waterproof in use, anti-
The problem of dirt, water-impervious, anti-overflow rouge.
According to technical solution provided by the utility model, a kind of water-sealed bearing, including outer ring, inner ring, steel ball, retainer,
Sealing ring, outer ring open up external seal slot, and inner ring opens up interior seal groove；Sealing ring include be wrapped in the first outer lip of sealing ring outer rim with
Second outer lip, and the first epipharynx positioned at sealing ring inner edge, the second epipharynx, third epipharynx, the 4th epipharynx；First outer lip and second
The first groove is formed between outer lip；The second groove is formed between first epipharynx and the second epipharynx, is formed between the second epipharynx and third epipharynx
Third groove；The axial direction of 4th epipharynx direction sealing ring；First outer lip is contacted with the second outer lip with external seal slot, the first epipharynx,
Second epipharynx and third epipharynx are contacted with interior seal groove.
First outer lip, second the first epipharynx of outer lip, the second epipharynx and third epipharynx are pointed generally in the radial direction of sealing ring.It is described
Waterproof sealing coil structures be an integral molding structure.
The rubber material of a kind of high resiliency, low friction is added between bearing outer ring and inner ring, outside the sealing ring and bearing
Circle and inner ring are sealed using complete Interference contact formula, while in order to which lift-off seal effect, bearing inner race and rubber seal use
Multilayer contact formula inclined-plane Seal Design does not influence the rotation of bearing to ensure that the contact surface of sealing, bearing outer ring with
Rubber seal ensure that water, the grease in outside using arc drainage design, cannot be introduced into Bearing inner.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the outer ring and sealing ring contact structures partial enlarged view of the utility model.
Fig. 3 is the inner ring and sealing ring contact structures partial enlarged view of the utility model.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
From Fig. 1-Fig. 3: the utility model includes outer ring 1, inner ring 2, steel ball 3, retainer 4, sealing ring 5, and outer ring 1 is opened
If external seal slot 6, inner ring 2 opens up interior seal groove 7；Sealing ring 5 include include the first outer lip 8 and second positioned at sealing ring outer rim
Outer lip 9, and the first epipharynx positioned at sealing ring inner edge, the second epipharynx, third epipharynx, the 4th epipharynx；Outside first outer lip 8 and second
The first groove is formed between lip 9；The second groove is formed between first epipharynx and the second epipharynx, and is formed between the second epipharynx and third epipharynx
Three grooves；The axial direction of 4th epipharynx direction sealing ring；First outer lip 8 is contacted with the second outer lip 9 with external seal slot 6, the first epipharynx,
Second epipharynx and third epipharynx are contacted with interior seal groove 7.
First outer lip 8, the second outer lip 9, the first epipharynx, the second epipharynx and third epipharynx are pointed generally in the radial direction of sealing ring.
The waterproof sealing coil structures are an integral molding structure.5 first outer lip 8 of sealing ring opens up the generation of external seal slot 6 with outer ring
The axially contact water for preventing outside, grease enter, and 5 second outer lip 9 of sealing ring opens up external seal slot 6 radially, axially together with outer ring
When contact prevent the water in outside, grease from entering, while preventing sealing ring 5 from producing relative rotation with outer ring 1, while preventing in bearing
Portion's grease overflows, and 5 first inner lip 9 of sealing ring opens up interior seal groove 7 with inner ring 2 and generates the axially contact water for preventing outside, oil
Rouge enters, and 5 second epipharynx of sealing ring and inner ring 2, which open up seal groove 7 and contact, prevents internal grease spilling, 5 third epipharynx of sealing ring
With inner ring 2 open up interior seal groove 7 contacts the water for preventing from penetrating into extremely, grease enters Bearing inner, the 4th epipharynx of sealing ring 5 with it is interior
Circle 2 opens up interior seal groove 7 and does not contact, and controls the bearing internal grease direction of motion, moves grease toward Bearing inner, forms lubrication
Circulation, avoids grease from moving out, prevents grease from overflowing.
Described it is characterized in that: it is one in " 5 " font seal groove, the inner ring 2 that the outer ring 1, which opens up external seal slot 6,
Opening up interior seal groove 7 is a seal groove "Z"-shaped；Sealing ring 5 is in " Y " font, sealing ring 5 and outer ring 2 with the contact of outer ring 1
Contact be in " hand " shape.
