Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of oil baffle formula ventilating mechanism is provided, have simple in structure, keeping off oily effect obviously promotes, anti-leakage of oil is effective, advantages such as it is reliable to ventilate solve traditional breather plug in the layout of the direction that fluid splashes, easily the problem of the speed changer breather plug leakage of oil that forms.
The present invention is achieved by the following technical solutions, the present invention includes: oil baffle, the oily dividing plate of retaining and ventilation assembly, wherein: oil baffle is arranged at by bolt on the housing of speed changer and with housing and forms a semiclosed shape chamber, keep off the below that oily dividing plate is fixedly set in oil baffle, the ventilation assembly is positioned at the housing side of speed changer and links with described semiclosed shape chamber.
Described oil baffle is semi-open structure, comprise base plate and with the vertically disposed baffle plate in the top of base plate, described baffle plate is a C shape structure, comprises three continuous identical shaped arc plates; Fixedly connected with the oily dividing plate of retaining in the bottom of described base plate;
The central authorities of described base plate are provided with vent;
The oily dividing plate of described shelves is the L word shape, and the one end is fixedlyed connected with the bottom vertical of base plate, and the other end parallels with base plate, and wherein: the area of the retaining oil dividing plate that parallels with base plate is greater than the area of described vent.
Described ventilation assembly comprises: rubber one-way valve, prolongation pipe and breather plug, wherein: prolong pipe and be rubber hose, prolongation Guan Yiduan interference fit connects the rubber one-way valve, and the other end connects breather plug.
Compared with prior art, advantage of the present invention is: keep off oily effect and obviously promote, speed changer ventilation leak preventing effect obviously promotes.

Embodiment
Below embodiments of the invention are elaborated, present embodiment is being to implement under the prerequisite with the technical solution of the present invention, provided detailed mode of execution and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: ventilation assembly 1, oil baffle 2, the oily dividing plate 3 of retaining and bolt 4, wherein, oil baffle 2 is fixedly set in by bolt 4 on the housing of speed changer and with housing and forms a semiclosed shape chamber, keep off the below that oily dividing plate 3 is fixedly set in oil baffle 2, ventilation assembly 1 is positioned at the housing side of speed changer and links with described semiclosed shape chamber.
As shown in Figure 2, described ventilation assembly 1 comprises: rubber one-way valve 5, prolongation pipe 6 and breather plug 7, and wherein: prolonging pipe 6 is rubber hose, and prolongation is managed 6 one end interference fit and is connected rubber one-way valve 5, and the other end connects breather plug 7.
As shown in Figure 3, the outside of described rubber one-way valve 5 is provided with rubber thin-walled 8.
Described rubber one-way valve 5 has the unidirectional logical effect that ends, after the speed changer running, when internal pressure increases, the rubber thin-walled 8 of rubber one-way valve 5 both wings is outwards heaved, externally exit and discharge the speed changer internal pressure, this moment, air-flow outwards discharged from the inner rubber one-way valve 5 that passes through of speed changer, and impurity and water etc. can't enter speed changer inside by contrary airflow direction.Behind the internal and external pressure balance of speed changer, the rubber thin-walled 8 of rubber one-way valve 5 both wings inwardly draws in, and rubber one-way valve 5 promptly forms locking, prevents that impurity and water etc. from entering speed changer inside.
As shown in Figure 4, described oil baffle 2 is semi-open structure, comprise base plate 9 and with the vertically disposed baffle plate 10 of a side of base plate 9, described baffle plate 10 is a C shape structure, comprises three continuous identical shaped arc plates 11; Fixedly connected with the oily dividing plate 3 of retaining in the bottom of described base plate 9;
The two ends of described arc plate 11 contact with the housing of speed changer;
The central authorities of described base plate 10 are provided with vent 12;
The oily dividing plate 3 of described shelves is the L word shape, and the one end is fixedlyed connected with the bottom vertical of base plate 9, and the other end parallels with base plate 9, and wherein: the area of the retaining oil dividing plate 3 that parallels with base plate 9 is greater than the area of described vent 12.By keeping off the vent 12 that oily dividing plate 3 blocks base plate 9 belows, make in the speed changer operation process, when gear stirs transmission oil and forms fluid and splash, keep off oily dividing plate 3 and block transmission oil and splash to vent 12, realize the effect of oil removal then.
As shown in Figure 5, substantially horizontal top is divided into transverse tube 13 in the described breather plug 7, at its end by being welded to connect an inclined tube 14, wherein: the internal diameter of transverse tube 13 is greater than the internal diameter of inclined tube 14, this one thick one thin structure helps forming certain positive air pressure to speed changer is inner, prevents that mist of oil from running out of to the speed changer outside by breather plug.
As shown in Figure 6, the oil baffle of this device is fixed on the housing of speed changer and with housing and forms a semiclosed shape chamber of not having oil naturally, on the direction that fluid splashes, form together auxiliary oil-blocking action at retaining oil dividing plate fixing below the oil baffle, when the inner fluid of speed changer splashes to the breather plug position, oil baffle and the oily dividing plate of retaining block transmission oil simultaneously, make transmission oil directly not splash to breather plug, and air can normally pass through breather plug, keeps speed changer internal pressure balance.The ventilation component design has the rubber one-way valve, guarantees that water or other impurity do not enter into speed changer inside under the breather plug trickle condition, guarantees that transmission oil is not subjected to water or other contaminating impurities.
