Preferably, the observation covers and is disposed with oil baffle.The beneficial effect of generation is can effectively prevent in gear-box
Lubricating oil splash enter condensing unit and Ventilated cap.
Preferably, being disposed with the particulate Si for adsorbing moisture in oil gas in airflow channel inside the Ventilated cap
Glue.The beneficial effect of generation is to adsorb to the moisture in gas, enters gear-box corrosion gear to prevent large quantity of moisture.
Preferably, being disposed with the molecular sieve for adsorbing moisture in oil gas in airflow channel inside the Ventilated cap.
The beneficial effect of generation is to adsorb to the moisture in gas, enters gear-box corrosion gear to prevent large quantity of moisture.
Preferably, the lower disposed in Ventilated cap interior air-flow channel has spongy layer.The beneficial effect of generation is sponge layer
On the other hand the particle of adsorption moisture can be supported not fall into gear-box with adsorption coagulation oil gas.
Preferably, the top in Ventilated cap interior air-flow channel is disposed with strainer.The beneficial effect of generation is that strainer can
Further filtering condensation is carried out to oil gas.
Compared with prior art, beneficial effects of the present invention:
1, solve the problems, such as that gear box venting structure is easy blocking.By increasing condensing unit and oil baffle, make to come from
After the oil gas of gear-box first obtains pretreatment in condensing unit, the content of lubricating oil is substantially reduced in oil gas, greatly reduces
The workload of Ventilated cap solves the problems, such as that Ventilated cap is easy blocking substantially.
2, ventilating structure has good economic effect and easy to maintain.Condensing unit is detachable, so that a kind of ventilative
Cap is matched by the condensing unit with different size can be applied to a variety of gear-boxes, in addition clean to the maintenance of condensing unit
It is very convenient, avoid financial burden caused by frequently replacement Ventilated cap.
