Breather plug 10 according to embodiments of the present invention is described in detail with reference to Fig. 1-Fig. 3.
Shown in reference picture 1, Fig. 2, breather plug 10 according to embodiments of the present invention can include hollow cock body 1, iron core 2,
Valve block component 3, upper lid 4 and elastic device 5.
The top and bottom of cock body 1 are opened wide respectively, and in other words, the inside of cock body 1 is through hole, through hole connection box house with
Outside casing, can be used to ventilate poor to reduce body inside and outside air pressure.
Iron core 2 is interference fitted in cock body 1, can prevent iron core 2 from being slid from cock body 1.It is formed with the outer peripheral face of iron core 2
Helicla flute 23, helicla flute 23 along iron core 2 axial screw extend.Helicla flute 23 can effectively increase the ventilation of lubrication oil vapour
Path, makes steam fully be liquefied as oil droplet, then flow back to box house along helicla flute 23.
Meanwhile, lubrication oil vapour increased the probability that oil gas collides the cell wall of helicla flute 23 when being revolved along helicla flute 23, make
Oil gas is more easy to be liquefied as oil droplet and is fallen after rise along helicla flute 23.
And, the outer wall of iron core 2 and the inwall directly contact of cock body 1, therefore the temperature of helicla flute 23 is relatively low, is conducive to lubricating oil to steam
Vapour is fully liquefied as oil droplet, and flows back to box house along helicla flute 23, prevents oil leak, so as to save lubricating oil.
Valve block component 3 closes the upper end open of cock body 1, can play a part of waterproof and dustproof, so as to prevent extraneous water
Vapour and dust enter box house through the upper end open of cock body 1.
Upper lid 4 is fixed on the upper end of cock body 1, and passage is provided with upper lid 4, and the gases at high pressure in casing pass through the ventilation
Discharge casing in hole.
Elastic device 5 is arranged in lid 4 and flexibly compresses valve block component 3.After the completion of assembling, elastic device 5 is in
Compressive state, such elastic device 5 can give valve block component 3 one lasting pressure, and valve block component 3 is compressed the upper end of cock body 1
Opening, so as to play better seal effect.
Breather plug 10 according to embodiments of the present invention has oil-leakage-prevention function, and lubrication oil vapour runs into the relatively low iron core of temperature
2, will there is liquefaction condensation, so as to flow back to box house along the helicla flute 23 of iron core 2, it is possible thereby to reduce mist of oil ejection, keep away
Exempt from the oil leak of breather plug 10, while having saved lubricating oil.
Lower end of the lower end of iron core 2 higher than cock body 1.In other words, the length of iron core 2 is less than the length of cock body 1, iron core 2
There is a certain distance lower end with the lower end of cock body 1, for stopping that lubricating oil is directly thrown on iron core 2.
Further, upper end of the upper end of iron core 2 less than cock body 1.That is, the upper end of iron core 2 also has one with the upper end of cock body 1
Set a distance, the space that the distance is formed can be used to store the lubricating oil that fraction is liquefied by oil and gas temporarily.In gravity
Under effect, or when stored lubricating oil is saved bit by bit to a certain extent, lubricating oil can be flowed back in casing again along helicla flute 23.
Shown in reference picture 3, iron core 2 can include core body 21 and the spiral salient 22 being arranged on the outer peripheral face of core body 21.
In the embodiment shown in fig. 3, spiral salient 22 is two, and two lower ends of spiral salient 22 are in the footpath of core body 21
Relative upwards, the upper end of two spiral salients 22 is diametrically opposed, and helicla flute 23 is limited between two spiral salients 22.Spiral shell
The outer wall of rotation raised 22 is brought into close contact with the inwall of cock body 1, and the mist of oil of lubricating oil can only be discharged by helicla flute 23, herein
During, mist of oil is liquefied as oil droplet to the cold, is flowed back in casing along helicla flute 23.
In other optional embodiments, spiral salient 22 can also be one, three or more bars.
Annular groove 11 is provided with the outer peripheral face of cock body 1, annular groove 11 is used to connect lid 4.Specifically, annular is recessed
Groove 11 is provided with annular protrusion 41 on the upper surface of cock body 1, upper lid 4, and annular protrusion 41 is fixed in annular groove 11.
In specific embodiment, the lower end of upper lid 4 can be made to cave in by way of extruding or riveting, form annular protrusion 41, and by annular
Raised 41 are connected in annular groove 11, so as to upper lid 4 be fixed together with cock body 1, the fixed effect of this kind of fixed form
It is good.
Upper lid 4 has roof 42, and elastic device 5 flexibly compresses valve block component 3 and roof 42, offered on roof 42 logical
Stomata, the passage can go out the gas pressure leak inside gearbox or decelerator, prevent box house air pressure excessive and cause
Casing is damaged.
Valve block component 3 can include gasket seal 31 and sheet metal 32, and the upper end that gasket seal 31 is sealed in cock body 1 is opened
At mouthful, gasket seal 31 can be rubber or nylon material pad, to play good sealing effectiveness.Sheet metal 32 is fixed on
On the upper surface of gasket seal 31, the intensity of sheet metal 32 is larger, can be used to bear the elastic force of elastic device 5, so as to prevent
Gasket seal 31 is influenceed sealing effectiveness by conquassation.
The outer peripheral face of the bottom of cock body 1 is provided with external screw thread, and the external screw thread is used for and the spiral shell on gearbox or decelerator
Pit screw thread coordinates.Breather plug 10 is backed out, extra setting can be thus avoid by the screwed hole to lubricating oil is added in casing
Filler plug, so as to further save cost.Hexagonal flange is additionally provided with cock body 1, hexagonal flange is located at externally threaded top.
Hexagonal flange is turned using spanner or sleeve barrel tool, cock body 1 just can be tightened or unclamp, so as to breather plug 10 is fixed on into casing
Unload down above or from casing.
The breather plug 10 of the vehicle of embodiment, including above-described embodiment according to a further aspect of the invention, is led to by setting this
Vent plug 10, it is possible to prevente effectively from oil leak at the breather plug 10 of gearbox or decelerator, so as to save lubricating oil, maintains
Cleaning around casing.
