Description
Technical field
The invention belongs to Micropressure safety valve technical fields, and in particular to a kind of hub reduction gear breather.
Background technology
Speed reducer is in certain industries, such as the high moisture of the dusty of coal and cement, water conservancy headstock gear and environmentally friendly aerator
In application, its air breather will not only have ventilative decompression function in environment, also there is dust-proof, moistureproof.And slow down at present
The either porous plug or ventilating cover generally used on machine can only all play ventilative decompression function, maintain in decelerating chassis body
Pressure and external atmosphere pressure dynamic balance, but speed reducer cannot be solved when out of service, extraneous minute dusts and moisture pass through
Their gas-permeable channels enter in decelerating chassis body, and lubricating oil in decelerating chassis body is caused to be contaminated and Moisture in Lube Oil ＆ content
It is exceeded, the problem of making the cleannes severe exacerbation of lubricating oil.Uncleanly lubricating oil can be to the mill of fatigue life of gear, oil sealing
Negative effect is played in the corrosion of damage and inner body, particularly bearing life is influenced huge.In the service life of bearing calculates,
The contamination factor of lubricating oil play the role of to bearing life correction factor it is vital, with passing for lubricant pollution coefficient
Subtract, bearing life correction factor drastically declines.Therefore, the function of speed reducer air breather is to the actual life of speed reducer
It influences very big.
Speed reducer is discharged because lubricating grease sends out gas thermogenetic by breather, it is desirable that is in speed reducer internal pressure
Not pressure release during 0.02Mpa, when internal pressure reaches 0.03MPa, breather open pressure release, speed reducer in hydraulic pressure 0.05MPa not
There can be water to enter speed reducer by breather.Current breather pressurize and pressure release range is small to be difficult to control, and dwell pressure and lets out
Phenomena such as pressure pressure precision can not also ensure, water is entered by breather in speed reducer after water under speed reducer can not effectively avoid.
Invention content
The technical problem to be solved by the present invention is to provide a kind of simple in structure, reasonable design, pressurize pressure release control it is accurate and
The preferable hub reduction gear breather of sealing effect.
It is of the invention to adopt the following technical scheme that solve above-mentioned technical problem, a kind of hub reduction gear breather, feature
It is to include housing, spring base, O-ring seal, spring, valve base, annular sealing strip and bonded washer, hull outside lower part is set
There is annular ligament angle, housing is connect by the bonded washer being sheathed on annular ligament angle with hub reduction gear box sealing, shell
Body is internally provided with axial step through-hole, and annular sealing strip, valve base, spring and bullet are equipped with successively on the step of axial step through-hole
The both ends of spring abutment, wherein spring are fixedly connected respectively with valve base and spring base, and valve base is used to compress annular sealing strip with shape
Into the sealing of axial step through-hole, spring base is sealingly fastened in by O-ring seal in axial step through-hole, O-ring seal with
Housing sidewall between annular sealing strip is equipped with the step gas vent tilted down.
Further preferably, be equipped with successively along airintake direction in the axial step through-hole of the annular sealing strip lower part baffle ring and
Filtering layer, guide ring are made of 304 stainless steel tubes.
The present invention efficiently solve hub reduction gear in particular circumstances in use, breather must have sealing and dustproof,
The problem of damp proof and ventilative decompression function；Pollution of the environmental contaminants to hub reduction gear lubricating oil effectively has been cut off, had both been extended
The replacement cycle of hub reduction gear lubricating oil, and the service life of hub reduction gear is improved, it is entirely capable of meeting coal, cement
Conveyer, environmentally friendly aerator, water conservancy headstock gear hub reduction gear are to the particular/special requirement of breather.In addition, the sealing position of housing
Using the ligament angle of reasonable design, not only ensure not damage caulking gum, but also can ensure there are enough sealing surfaces with caulking gum,
Sealing effect is preferable；The gas storage that step gas vent inclined design reaches in breather passage is maximum, and then is preferably formed
Seal cavity reduces the possibility that water enters breather cavity to the greatest extent.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1- spring bases, 2-O type sealing rings, 3- housings, 4- springs, 5- valve bases, 6- bonded washers, 7- filtering layers, 8-
Baffle ring, 9- bands, 10- step gas vents.
Specific embodiment
With reference to attached drawing detailed description of the present invention specific technical solution.A kind of hub reduction gear breather, including housing 3,
Spring base 1, O-ring seal 2, spring 4, valve base 5, annular sealing strip 9 and bonded washer 6,3 outer lower portion of housing are equipped with annular
Ligament angle, housing 3 is connect by the bonded washer 6 being sheathed on annular ligament angle with hub reduction gear box sealing, in housing 3
Portion is equipped with axial step through-hole, and annular sealing strip 9, valve base 5, spring 4 and bullet are equipped with successively on the step of axial step through-hole
Spring abutment 1, the wherein both ends of spring 4 are fixedly connected respectively with valve base 5 and spring base 1, and valve base 5 is used to compress annular sealing strip
9 to form the sealing of axial step through-hole, and spring base 1 is sealingly fastened in by O-ring seal 2 in axial step through-hole, O-shaped close
3 side wall of housing between seal 2 and annular sealing strip 9 is equipped with the step gas vent 10 tilted down, the annular sealing strip 9
It is equipped with baffle ring 8 and filtering layer 7 successively along airintake direction in the axial step through-hole of lower part, guide ring 8 is by 304 stainless steel control
Into.
The present invention operation principle be：The pressurize of hub reduction gear is realized by the closing and unlatching of breather sealing position
And decompression function, when hub reduction gear internal pressure is less than dwell pressure, breather sealing position is closed to reach sealing effect；
When hub reduction gear internal pressure reaches vent pressure, breather work, breather sealing position, which is opened, carries out pressure release, when letting out
When hub reduction gear internal pressure power is less than dwell pressure after pressure, breather sealing position self-closed under the action of the spring.
Have been shown and described above the basic principle of the present invention, main feature and advantage, do not depart from spirit of the invention and
Under the premise of range, the present invention also has various changes and modifications, these changes and improvements both fall within claimed invention
Range.
