Description

A kind of gearbox breathing circuit filter

Technical field:

The utility model relates to gearbox technical fields, and in particular to a kind of gearbox breathing circuit filter.

Background technique:

The lubricating condition of actuated element is more demanding in gearbox, slightly improper to damage actuated element damage, even Scrap, so there is more lubricating oil in gearbox body, initial lubrication, cooling effect generated higher since oil temperature increases Air pressure realizes the balance and heat dissipation of air pressure so needing to install breathing equipment on gearbox.The breathing equipment of the prior art (as shown in Figure 3), actuated element such as gear can make oil liquid splash in the running, and the oil liquid of splashing can be by oil filling pipe toward oil filler Lid is emerged, and after a period of time, after the sponge in cap has inhaled more oil, forms sealing structure, sponge, which loses, to be breathed The effect of filter；Oil liquid when continuing to use in sponge can be sprayed with the air-flow of exhalation, lead to filler cap Leakage.

Utility model content:

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of gearbox breathing circuit filter, it Oil-gas Separation can be effectively performed in the combination of two pieces of partitions and strainer, solve filler cap Leakage.

The scheme that the utility model solves the technical problem is:

A kind of gearbox breathing circuit filter, including seal be fixed on gearbox cabinet upper side wall on oil filling pipe, Oil filling pipe is communicated with the inner cavity of the cabinet of gearbox, and the top of oil filling pipe is socketed with filler cap, formed on filler cap with The respiration channel that oil filling pipe communicates is installed with sponge in the middle part of respiration channel, is equipped with gas and oil separating plant, institute in the oil filling pipe Stating gas and oil separating plant includes the plastic sheath being socketed in oil filling pipe, and strainer, the plastic sheath are fixed on the inner wall of plastic sheath It is clamped between two pieces of partitions setting up and down, the outer wall sleeve of partition is simultaneously fixed on the upper end inner wall of oil filling pipe, plastic sheath Outer wall be pressed against on the inner wall of oil filling pipe, formed on the partition it is several up and down perforative apertures.

Muti-piece uniformly distributed spoiler up and down is respectively fixed in the inner left wall and right side inner wall of the oil filling pipe, be fixed on plus Spoiler in the inner left wall of oil pipe is arranged in a staggered manner up and down with the spoiler on the right side inner wall for being fixed on oil filling pipe, the resistance Flowing plate is located at the lower section of the partition of downside.

The spoiler right low left high being fixed in the inner left wall of oil filling pipe is obliquely installed, and is fixed in the right side of oil filling pipe Spoiler left low and right high on wall is obliquely installed.

Inwardly protruded ring rubber rib, the upper end outer wall of the oil filling pipe are fixed on the inner wall of the filler cap Upper molding is fluted, and ring rubber rib are buckled in groove.

The protrusion effect of the utility model is:

Compared with prior art, Oil-gas Separation can be effectively performed in the combination of its two pieces of partitions and strainer, solve and add Oil port cover Leakage.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram (lateral dotted line is oil surface level in figure) of the utility model；

Fig. 2 is partial enlarged view of the Fig. 1 about A；

Fig. 3 is the structural schematic diagram of the breathing equipment of the gearbox of the prior art.

Specific embodiment:

Embodiment, is shown in as shown in Figure 1 to Figure 2, a kind of gearbox breathing circuit filter, is fixed on gearbox including sealing Oil filling pipe 1 on the upper side wall of cabinet, oil filling pipe 1 are communicated with the inner cavity of the cabinet of gearbox, and the top of oil filling pipe 1, which is socketed with, to be added Oil port cover 2 forms the respiration channel 201 communicated with oil filling pipe 1 on filler cap 2, and the middle part of respiration channel 201 is installed with sea Silk floss 3, the oil filling pipe 1 is interior to be equipped with gas and oil separating plant, and the gas and oil separating plant includes the plastic sheath being socketed in oil filling pipe 1 4, strainer 5 is fixed on the inner wall of plastic sheath 4, and the plastic sheath 4 is clamped between two pieces of partitions 6 setting up and down, partition 6 Outer wall sleeve is simultaneously fixed on the upper end inner wall of oil filling pipe 3, and the outer wall of plastic sheath 4 is pressed against on the inner wall of oil filling pipe 3, it is described every Several perforative apertures 601 up and down are formed on plate 6.

Further, to be respectively fixed with muti-piece on the inner left wall of the oil filling pipe 1 and right side inner wall uniformly distributed up and down Spoiler 7, the spoiler 7 being fixed in the inner left wall of oil filling pipe 1 and the spoiler being fixed on the right side inner wall of oil filling pipe 1 About 7 are arranged in a staggered manner, and the spoiler 7 is located at the lower section of the partition 6 of downside.

Further, 7 right low left high of spoiler being fixed in the inner left wall of oil filling pipe 1 is obliquely installed, fixed 7 left low and right high of spoiler on the right side inner wall of oil filling pipe 1 is obliquely installed.

Further, inwardly protruded ring rubber rib 8 are fixed on the inner wall of the filler cap 2, it is described Fluted 101 are formed on the upper end outer wall of oil filling pipe 1, ring rubber rib 8 are buckled in groove 101, and ring rubber rib 8 can increase The stability for adding filler cap 2, prevents it from skidding off.

Working principle: when gearbox operation, gear rotation drives the lubricating oil splash in gearbox, the lubricating oil of splashing The aperture 601 of partition 6 through downside enters in strainer 5, and blocking and filtration through strainer 5, the oil liquid of splashing loses dynamic Power flows back into cabinet from the aperture 601 of the partition 6 of downside, and gas can not be continued upstream by the effect of strainer 5, and gas is through sea The external world is flowed out to through respiration channel 201 again after the filtration of silk floss 3, and extraneous gas can also be from respiration channel 201 and sponge Filtering after enter cabinet, to realize respiration；The spoiler 7 being arranged in oil filling pipe 1 can play the oil liquid of splashing To certain barrier effect, the power of oil liquid is reduced, the filter pressure of strainer 5 can be further decreased.

Finally, embodiment of above is merely to illustrate the utility model, and it is not limitation of the utility model, related skill The those of ordinary skill in art field can also make various changes in the case where not departing from the spirit and scope of the utility model Change and modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the patent protection model of the utility model Enclosing should be defined by the claims.
