Description
Technical field
The utility model relates to bearing sealed ring technical fields, specially internal diameter stomata water pump bearing sealing ring.
Background technique
The application places of bearing sealed ring are very extensive, are mainly used for industry, automobile, railway, mining machinery and boat
Empty space flight etc., we mainly introduce automobile and engineering machinery bearing sealed ring, mainly there is seal automobile hub bearing, sealing vapour
Railway carriage Bearing with wheel, seal automobile clutch bearing, seal automobile water pump bearing, seal automobile transmission shaft bearing, seal automobile
The occasions such as steering column bearing, seal automobile air throttle needle bearing, Seal mechanical bearing.
The design outer diameter port sealing structure of current original internal diameter stomata water pump bearing sealing ring is all that stomata setting exists
Sealing ring outer lip diametrically, only considered the exhaust gas inside decompression problem under water pump bearing high temperature and high speed, not account for height
Seal request of the water pump bearing under low speed or static state after temperature, high speed, leakproofness is poor, for this purpose, it is proposed that internal diameter stomata water pump
Bearing sealed ring.
Utility model content
The purpose of this utility model is to provide internal diameter stomata water pump bearing sealing rings, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: internal diameter stomata water pump bearing sealing ring, including
Bearing sealed ring ontology, the bearing sealed ring inside are equipped with cyclic annular matrix scaffold, are equipped with and seal on the outside of the bearing sealed ring
Outer lip, and seal outer lip and contacted with bearing outer ring, it is equipped on the inside of the bearing sealed ring in the first sealing epipharynx and the second sealing
Lip, and the first sealing epipharynx and the second sealing epipharynx are contacted with bearing inner race respectively, the lip diameter of the second sealing epipharynx
It is equipped with stomata.
Preferably, the sealing outer lip cross-sectional view shape is trapezoidal.
Preferably, the bearing sealed ring, sealing outer lip, the first sealing epipharynx and the second sealing epipharynx are structure as a whole,
And it is made of the rubber material of high resiliency, low friction.
Preferably, a v-shaped cavity is formed between the first sealing epipharynx and the second sealing epipharynx.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model designs novel bearing seal coil structures, equal using the first sealing epipharynx and the second sealing epipharynx
It is contacted with bearing inner race, the leakproofness so as to effectively guarantee internal sets stomata compared with traditional ring structure
It sets the lip for sealing epipharynx second diametrically, can guarantee there is epipharynx lip to contact with bearing inner race always, guarantee leakproofness.
Detailed description of the invention
Fig. 1 is the utility model schematic cross-sectional view.
In figure: 1- bearing sealed ring；2- ring-type matrix scaffold；3- seals outer lip；4- first seals epipharynx；5- second is sealed
Epipharynx；6- stomata；7-V type chamber.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, internal diameter stomata water pump bearing sealing ring in diagram, including 1 ontology of bearing sealed ring, the bearing are close
It is equipped with cyclic annular matrix scaffold 2 inside seal 1, sealing outer lip 3 is equipped on the outside of the bearing sealed ring 1, and seal outer lip 3 and bearing
Outer ring contacts, and the first sealing epipharynx 4 and the second sealing epipharynx 5, and the first sealing epipharynx 4 are equipped on the inside of the bearing sealed ring 1
It is contacted respectively with bearing inner race with the second sealing epipharynx 5, the lip of the second sealing epipharynx 5 is diametrically equipped with stomata 6.
Seal 3 cross-sectional view shape of outer lip be it is trapezoidal, play the role of and bearing seal cooperate.
Bearing sealed ring 1, sealing outer lip 3, first seal epipharynx 4 and the second sealing epipharynx 5 is structure as a whole, and using high
Elastic, low friction rubber material is made, and then is convenient for the production and processing of sealing ring.
A v-shaped cavity 7 is formed between first sealing epipharynx 4 and the second sealing epipharynx 5, is deposited convenient for the discharge of bearing inner wall gas
Storage.
Specifically, after bearing sealed ring 1 is mounted on bearing, in static state or when slowly running, pass through sealing outer lip 3 and axis
The contact of bearing outer-ring inner wall, the first sealing epipharynx 4 and the second sealing epipharynx 5 are contacted with bearing inner race, can guarantee the sealing of bearing
Property, in internal diameter stomata water pump bearing high-speed rotation, Bearing inner can generate high temperature because of high-speed friction, need inner wall gas
The gas of Bearing inner is discharged in v-shaped cavity 7 by the stomata 6 on the second sealing epipharynx 5 by discharge at this time to be vented decompression,
So that air pressure inside is reached stable, and simultaneously can after high temperature, high speed seal request of the water pump bearing under low speed or static state.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to
Non-exclusive inclusion, so that the process, method, article or equipment including a series of elements is not only wanted including those
