It is shown in reference picture 1, Fig. 2, breather plug 10 according to an embodiment of the present invention may include hollow cock body 1, iron core 2,
Valve block component 3, upper cover 4 and elastic device 5.
The top and bottom of cock body 1 are opened wide respectively, in other words, inside cock body 1 be through-hole, the through-hole be connected to box house with
Outside cabinet, it is poor to reduce body inside and outside air pressure to can be used for ventilating.
Iron core 2 is interference fitted in cock body 1, can prevent iron core 2 from sliding out of cock body 1.It is formed on the outer peripheral surface 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 sufficiently be liquefied as oil droplet, then flows back to box house along helicla flute 23.
Meanwhile oil vapour is lubricated when revolving along helicla flute 23, the probability of oil gas collision 23 cell wall of helicla flute is increased, is made
Oil gas is easier to be liquefied as oil droplet and fall after rise along helicla flute 23.
Moreover, 2 outer wall of iron core is directly contacted with 1 inner wall of cock body, therefore 23 temperature of helicla flute is lower, is conducive to lubricating oil steaming
Vapour is sufficiently liquefied as oil droplet, and flows back to box house along helicla flute 23, oil leak is prevented, to save lubricating oil.
Valve block component 3 closes the upper end opening of cock body 1, can play the role of waterproof and dustproof, to prevent outside water
The upper end opening of vapour and dust through cock body 1 and enter box house.
Upper cover 4 is fixed on the upper end of cock body 1, and venthole is provided in upper cover 4, and the intracorporal high pressure gas of case passes through the ventilation
Cabinet is discharged in hole.
Elastic device 5 is arranged in upper cover 4 and flexibly compresses valve block component 3.After the assembly is completed, 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 to the upper end of cock body 1
Opening, to play better seal effect.
Breather plug 10 according to an embodiment of the present invention has the function of that oil-leakage-prevention, lubrication oil vapour encounter the lower iron core of temperature
2, liquefaction condensation will occur, so that the helicla flute 23 along iron core 2 flows back to box house, it is possible thereby to reduce mist of oil ejection, keep away
Exempt from 10 oil leak of breather plug, while saving lubricating oil.
The lower end of iron core 2 is higher than the lower end of 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 are a certain distance in lower end and the lower end of cock body 1, for stopping lubricating oil to be directly thrown on iron core 2.
Further, the upper end of iron core 2 is lower than the upper end of cock body 1.That is, the upper end of iron core 2 and the upper end of cock body 1 also have one
Set a distance, the space which forms can be used to lubricating oil made of interim storage fraction is liquefied as oil and gas.In gravity
Under effect, or when stored lubricating oil is saved bit by bit to a certain extent, lubricating oil can flow back in cabinet again along helicla flute 23.
Referring to shown in Fig. 3, iron core 2 may include core 21 and the spiral salient 22 that is arranged on the outer peripheral surface of core 21.
In the embodiment shown in fig. 3, spiral salient 22 is two, the diameter of the lower ends of two spiral salients 22 in core 21
Opposite upwards, the upper end of two spiral salients 22 is diametrically opposed, limits helicla flute 23 between two spiral salients 22.Spiral shell
The inner wall of the outer wall and cock body 1 of rotation protrusion 22 fits closely, and the mist of oil of lubricating oil can only be discharged by helicla flute 23, herein
In the process, mist of oil is liquefied as oil droplet to the cold, flows back in cabinet along helicla flute 23.
In other optional embodiments, spiral salient 22 is also possible to one, three or more.
Annular groove 11 is provided on the outer peripheral surface of cock body 1, annular groove 11 is for connecting upper cover 4.Specifically, annular is recessed
Slot 11 is provided with annular protrusion 41 on the upper surface of cock body 1, upper cover 4, and annular protrusion 41 is fixed in annular groove 11.?
In specific embodiment, the lower end of upper cover 4 can be made to invaginate by way of extruding or riveting, form annular protrusion 41, and will be annular
Protrusion 41 is connected in annular groove 11, so that upper cover 4 and cock body 1 are fixed together, the fixed effect of such fixed form
It is good.
Upper cover 4 has roof 42, and elastic device 5 flexibly compresses valve block component 3 and roof 42, offers on roof 42 logical
Stomata, the venthole can go out the gas pressure leak inside gearbox or retarder, prevent box house air pressure excessive and cause
Cabinet damage.
Valve block component 3 may 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 gasket, to play good sealing effect.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 the elastic force for bearing elastic device 5, to prevent
Gasket seal 31 is crushed and influences sealing effect.
The outer peripheral surface of the lower end of cock body 1 is provided with external screw thread, which is used for and the spiral shell on gearbox or retarder
Pit is threadedly engaged.Breather plug 10 is backed out, lubricating oil can be added into cabinet by the threaded hole, thus avoid additionally being arranged
Filler plug, to further save cost.Hexagonal flange is additionally provided on cock body 1, hexagonal flange is located at externally threaded top.
Hexagonal flange is turned using spanner or sleeve barrel tool, can tighten or unclamp cock body 1, so that breather plug 10 is fixed on cabinet
Above or from cabinet unload down.
The vehicle of embodiment according to a further aspect of the invention, the breather plug 10 including above-described embodiment are logical by the way that this is arranged
Vent plug 10, it is possible to prevente effectively from oil leak maintains to save lubricating oil at the breather plug 10 of gearbox or retarder
Cleaning around cabinet.
